                           FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements, which give our current
expectations of future events. You will recognize these statements because they
do not strictly relate to historical or current facts. Such statements may use
words such as "anticipate," "estimate," "expect," "project," "intend," "think,"
"believe," "will," "should" and other words or terms of similar meaning in
connection with any discussion of our future performance. For example, these
include statements relating to future actions, future performance, expenses and
the impact of the capital markets on our liquidity. From time to time, we also
may provide oral or written forward-looking statements in other material
released to the public.

     Any or all of our forward-looking statements in this prospectus and in any
other public statements we make may turn out to be incorrect. They can be
affected by inaccurate assumptions or by known or unknown risks and
uncertainties. Many factors, which cannot be predicted with certainty, will be
important in determining our future results. Among such factors are:

     - governmental, statutory, regulatory or administrative changes or
       initiatives affecting us, the guarantors, our facilities, the contracts

U.S. FEDERAL INCOME TAX
  CONSEQUENCES................   Your exchange of outstanding bonds for bonds to
                                 be issued in the exchange offer will not result
                                 in any gain or loss to you for U.S. federal
                                 income tax purposes.

USE OF PROCEEDS...............   We will not receive any cash proceeds from the
                                 exchange offer.

EXCHANGE AGENT................   The Chase Manhattan Bank.

CONSEQUENCES OF FAILURE TO
EXCHANGE......................   Outstanding bonds that are not tendered or that
                                 are tendered but not accepted will continue to
                                 be subject to the restrictions on transfer that
                                 are described in the legend on those bonds. In
                                 general, you may offer or sell your outstanding
                                 bonds only if they are registered under, or
                                 offered or sold under an exemption from, the
                                 Securities Act and applicable state securities
                                 laws. We, however, will have no further
                                 obligation to register the outstanding bonds.
                                 If you do not participate in the exchange
                                 offer, the liquidity of your bonds could be
                                 adversely affected.

CONSEQUENCES OF EXCHANGING
YOUR BONDS....................   Based on interpretations of the staff of the
                                 SEC, we believe that you may offer for resale,
                                 resell or otherwise transfer the bonds that we
                                 issue in the exchange offer without complying
                                 with the registration and prospectus delivery
                                 requirements of the Securities Act if you:

                                 -  acquire the bonds issued in the exchange
                                    offer in the ordinary course of your
                                    business;

                                 -  are not participating, do not intend to
                                    participate, and have no arrangement or
                                    undertaking with anyone to participate, in
                                    the distribution of the bonds issued to you
                                    in the exchange offer; and

                                 -  are not an "affiliate" of our company as
                                    defined in Rule 405 of the Securities Act.

                                 If any of these conditions are not satisfied
                                 and you transfer any bonds issued to you in the
                                 exchange offer without delivering a proper
                                 prospectus or without qualifying for a

                                 or indemnify you against any liability you may
                                 incur.

                                 Any broker-dealer that acquires bonds in the
                                 exchange offer for its own account in exchange
                                 for outstanding bonds which it acquired through
                                 market-making or other trading activities, must
                                 acknowledge that it will deliver a prospectus
                                 when it resells or transfers any bonds issued
                                 in the exchange offer. See "Plan of
                                 Distribution" for a description of the

                                   to the excess, if any, of

                                   (a) the present value of all interest and
                                   principal payments scheduled to become due in
                                   respect to the bonds (which is to be
                                   determined on the basis of a discount rate
                                   equal to the sum of a treasury rate plus 25
                                   basis points) over

                                   (b) the outstanding principal amount of the
                                   applicable bonds.

MANDATORY REDEMPTION..........   The bonds will be subject to a mandatory
                                 redemption in whole or in part in the event we
                                 receive casualty insurance proceeds or
                                 condemnation proceeds, as applicable, in
                                 respect of any loss or damage to or
                                 condemnation or other governmental taking of
                                 any of our facilities or any part thereof, in
                                 excess of $10 million; provided that we will
                                 first be permitted to repair or rebuild such
                                 facilities, or parts thereof, where there are
                                 sufficient funds (including such insurance or
                                 condemnation proceeds) to do so, and if we
                                 provide an officer's certificate that certifies
                                 that no material adverse effect on us could
                                 reasonably be expected to result.

                                 In the event that we repair or rebuild our
                                 facilities and the insurance or condemnation
                                 proceeds are greater than the cost of such
                                 repair or rebuilding and if such excess amount
                                 is greater than $5 million, only the remaining
                                 insurance or condemnation proceeds over $5
                                 million will be used for a mandatory redemption
                                 or a repayment of senior secured indebtedness.

                                 In the event of a mandatory redemption, the
                                 redemption price for the bonds will be 100% of
                                 the principal amount of the bonds being
                                 redeemed plus interest accrued through the date
                                 of redemption. Upon the occurrence of any event
                                 requiring a redemption of bonds, we will be
                                 required to redeem the bonds and repay other
                                 senior secured indebtedness on a pro rata basis
                                 in an aggregate amount equal to the loss
                                 proceeds to be applied as described above.

CHANGE OF CONTROL.............   Upon the occurrence of events involving a
                                 change of control, we will be required to offer
                                 to repurchase all or any part of the
                                 outstanding bonds on the immediately following
                                 payment date at a cash price equal to 101% of
                                 the then outstanding principal amount of the
                                 bonds, plus accrued and unpaid interest to the
                                 date of payment. A change of control means:

                                 - the acquisition of ownership, directly or
                                   indirectly, beneficially or of record or

                                   meaning of the Exchange Act and the rules of

                                   ownership interests representing more than
                                   50% of the aggregate ordinary voting power

                                 However, there will be no change of control if
                                 either:

                                 - we receive a confirmation of the ratings of
                                   the bonds in effect immediately prior to the
                                   occurrence of the change of control; or

                                 - the change of control is approved by holders
                                   of bonds holding at least 66 2/3% in

                                   then-outstanding bonds.


DEBT SERVICE RESERVE
ACCOUNT.......................   NRG Northeast established a debt service
                                 reserve account for the benefit of the holders
                                 of the bonds. This account must contain at all
                                 times a sufficient amount to pay the projected
                                 principal and interest on all series of bonds
                                 due on the next scheduled payment date for each
                                 series of bonds. We do not have to fund this
                                 account with cash if we obtain an acceptable
                                 debt service reserve support instrument, which
                                 may be either an unconditional guarantee by NRG
                                 Energy or any of its affiliates other than NRG
                                 Northeast (so long as NRG Energy or such
                                 affiliate maintains a long-term senior
                                 unsecured debt rating of "Baa3" or better by
                                 Moody's and "BBB-" or better by S&P) or a
                                 letter of credit provided by a commercial bank
                                 or other financial institution with a long-term
                                 senior unsecured debt rating of "A2" or better
                                 by Moody's and "A" or better by S&P. The
                                 trustee will disburse funds from this account
                                 only to pay principal and interest on, and fees
                                 in respect of, the bonds in certain
                                 circumstances. Currently the debt service
                                 reserve requirement is being satisfied by a
                                 guarantee given by NRG Energy.

                                 - are senior obligations of NRG Northeast;

                                 - are equal in right of payment to all of NRG
                                   Northeast's existing and future senior

                                   guarantor's indebtedness, which is restricted
                                   to intercompany notes.

COVENANTS OF NRG NORTHEAST....   The terms of the indenture require NRG
                                 Northeast to, among other things:

                                  THE COMPANY


     NRG Northeast Generating LLC is a Delaware limited liability company which,
through its family of subsidiaries, owns electric power generation plants in the
northeastern region of the United States. NRG Northeast is an indirect,
wholly-owned subsidiary of NRG Energy which has made a net investment of
approximately $921 million in NRG Northeast as of June 30, 2000.


     We own a total of ten fossil fuel-fired and six remote gas turbine electric
power generation plants located in Connecticut, Massachusetts and New York,
providing approximately 6,495 MW of capable generating capacity. There are a
variety of ways in which the capacity of electric power generation plants can be
measured. We have chosen to express the capacity of our plants in terms of
capable generating capacity throughout this prospectus. A table summarizing the
characteristics of these facilities is set forth on page 12. We are a major
owner of independent electric power generation in terms of net megawatts of
generating capacity in the northeastern region of the United States.

     Our assets represent a diversified regional base of competitive generating
facilities close to major load centers. Our revenues are derived from base-load
facilities, intermediate load facilities and peaking facilities. The facilities
are diversified in terms of fuel usage and include coal, natural gas and fuel
oil plants.

     Our facilities sell their electrical power to diversified customers and
markets. In the first four calendar years of the term of the bonds, we expect to
sell a significant portion of our power pursuant to transition power sales
contracts with certain of the parties from whom we purchased the facilities. We
expect to sell the remainder of our power during this period primarily by
bidding into the New England Power Pool, which we will refer to as the NEPOOL,
and the New York Power Pool, which we will refer to as the NYPP (including the
area of the NYPP which is located in New York City and certain surrounding areas
which we will refer to as the New York City in-city market), the power pools in
which our facilities are located, and power pools in other areas. In later
years, we will look to maximize our revenues by seeking to optimize the mix of
sales pursuant to contracts and sales directly into these pools.

     The facilities were purchased at prices we believe to be competitive
compared to recent auctions of generation assets in the northeastern region of
the United States. In addition, we believe that:

     - The Dunkirk and Huntley facilities are among the lowest variable cost
       fossil fuel plants that sell into the NYPP; we will operate these assets
       as base-load facilities.

     - The Connecticut facilities are strategically positioned for sales into
       the NEPOOL and have a competitive advantage on transmission charges; we
       will operate these facilities as peaking and intermediate facilities to
       take advantage of market volatility.

     - The Somerset facility provides low variable cost capacity, strategically
       positioned to sell power into the NEPOOL; we intend to operate this
       facility as a peaking and base-load facility, depending on market
       conditions.

     - The Oswego facility provides very low cost capacity and is a source of
       excess emissions allowances that can be utilized at our other facilities;
       we expect to operate this facility as a peaking facility.

     - The Arthur Kill and Astoria facilities are located in the New York City
       in-city market and represent approximately 20% of installed capacity
       inside this transmission constrained area. We expect to benefit from the
       fact that load serving entities in the New York City in-city market must
       currently contract for 80% of their load obligation from in-city
       resources and there is limited potential to construct new in-city
       generation capacity or to gain transmission access to other generation
       capacity. We expect to operate the Arthur Kill facility as an
       intermediate and peaking facility and the Astoria facility as a peaking
       facility.

     We believe certain of the facilities and facility sites provide
opportunities for repowering or expansion of generation capacity. We also
believe that the diversity of our facilities, in terms of operating
characteristics, fuel sources, markets served, as well as their locational
advantages, puts us in a position to realize overall operational and financial
management synergies relating to integration of our fuel supply management and

                                       10

operating activities. Our relationship with NRG Energy allows us to draw on its
years of experience in the power sector by contracting with it and its
affiliates for many of these services.

     NRG Northeast was formed for the purpose of financing, acquiring, owning,
operating and maintaining, through its subsidiaries and affiliates, the
independent electric generating facilities described in the following chart and
any others that we may acquire in the future.


     Our headquarters and principal executive offices are located at 901
Marquette Avenue, Suite 2300, Minneapolis, Minnesota 55402. Our telephone number
is (612) 373-5300.

OUR BUSINESS

     We are a major owner of independent electric power generation in the
northeastern region of the United States. Our regional base of competitive
generating facilities is close to major load centers. We intend to pursue a
strategy of enhancing profitability and competitiveness of these facilities
through their efficient operation. We believe the diversity of our facilities,
in terms of operational characteristics and location in and access to multiple
power pools and fuel sources, is an important part of this strategy.

     In order to operate our facilities and be competitive, we need to address
power marketing, fuel procurement, emissions management and operations and
maintenance issues relating to the facilities. We are utilizing certain
resources of NRG Energy and its affiliates by entering into contracts with NRG
Energy, NRG Power Marketing and subsidiaries of NRG Operating Services, to
provide key administrative, marketing and operational services to us. An example
of these contractual arrangements is shown in a diagram on page 15.

     In particular, NRG Power Marketing, a wholly-owned subsidiary of NRG
Energy, has entered into power sales and agency agreements with each of the
guarantors for terms of approximately 30 years. NRG Power Marketing provides all
power marketing services, fuel procurement services and emissions management
services for the guarantors.

     POWER MARKETING.  NRG Power Marketing provides power marketing services to
the guarantors, including scheduling, pool bidding, contract management and
bilateral sales of excess capacity, energy and ancillary services, with gross
receipts less costs incurred due to the guarantors from such activities flowing
to NRG Northeast. NRG Power Marketing has the exclusive rights to market all
capacity, energy and ancillary services from the guarantors that the guarantors
have not otherwise committed under other contracts.

     FUEL PROCUREMENT.  NRG Power Marketing provides fuel procurement services
for natural gas, coal and oil purchasing; fuel inventory management; and
transportation arrangements. As part of NRG Northeast's fuel procurement
strategy, NRG Power Marketing will pursue short and intermediate fuel contracts
to hedge power sales contracts and other forward sales of power.

     EMISSIONS MANAGEMENT.  NRG Power Marketing provides emissions management
services for tracking, procurement, sales and allocation of emission allowances.
NRG Power Marketing will also assist the guarantors in performing ongoing
analyses comparing costs of installing and operating environmental control
equipment to emissions allowance procurement.

     RISK MANAGEMENT.  NRG Power Marketing will utilize certain risk management
policies and procedures to assist us with our objectives of maximizing net
operating margins while minimizing the risks associated with the cash flows
derived from these assets. Key risk management guidelines adopted by NRG Power
Marketing include: (i) a general prohibition on speculative activities; (ii)
mitigation of operational risk by not allowing more than 50% of available output
not already contracted to be sold forward unless approved by the NRG Power
Marketing board of directors; (iii) approval of counter-parties and their
trading limits by NRG Energy's treasury; and (iv) fuel and emissions allowance
requirements to be matched with future power sales commitments. These risk
management policies and procedures can only be changed by NRG Power Marketing's
board of directors.

     OPERATIONS AND MAINTENANCE.  Each of the guarantors has entered into an
operation and maintenance agreement with a separate subsidiary of NRG Operating
Services (other than the guarantors which own the Connecticut Jet and Middletown
facilities, which share an operator), which is a wholly-owned subsidiary of NRG
Energy. NRG Energy, through NRG Operating Services or other subsidiaries,
currently has contracts for the operations and maintenance of approximately
7,800 MW of power generation at thirty-one facilities worldwide, excluding the
NRG Northeast assets. Each NRG Operating Services subsidiary will be responsible
for operating and maintaining specific facilities.


     SIGNIFICANT CUSTOMERS.  We derived approximately 85.6% of our 1999 revenues
from three customers: NiMo (35.0%), ConEd (33.0%) and Eastern Utility
Association (17.6%). We sell energy and capacity to these customers under
transition agreements expiring in 2003, 2002 and 2009, respectively. For the
first six


                                       13
<PAGE>   20


months of 2000, we derived approximately 87% of our revenues from three
customers: the independent system operator for the NYPP (39%), CL&P (31%) and
NiMo (17%). We sell energy and capacity to CL&P under a standard offer service
wholesale sales agreement expiring in 2003.


OUR OWNERSHIP


     We are indirectly wholly-owned by NRG Energy, a leading participant in the
independent electric power generation industry throughout the world. Established
in 1989, NRG Energy is primarily engaged in the acquisition, development,
ownership and operation of power generation facilities and the sale of energy,
capacity and related products. On June 5, 2000, NRG Energy completed the initial
public offering of approximately 32 million shares of its common stock,
representing approximately 18% of its common equity. Upon completion of the
offering, Northern States Power Company (now Xcel Energy Inc.) owned
approximately 82% of the stock outstanding and 98% of the combined voting power
of NRG Energy's common stock and class A common stock.



     In August 2000, New Century Energies, Inc. merged with and into Northern
States Power. Northern States Power, the corporation surviving the merger, was
renamed Xcel Energy Inc. As a result of the merger, the shares of NRG Energy's
common stock and class A common stock previously owned by Northern States Power
are now owned by Xcel Energy through its wholly-owned subsidiary Xcel Wholesale
Energy Group.



     Xcel Energy is one of the ten largest electricity and natural gas companies
in the United States. Xcel Energy has six public utility subsidiaries that
collectively serve approximately 3,080,000 electric customers and 1,500,000 gas
customers in twelve states, and it has numerous non-utility subsidiaries,
including NRG Energy, which are engaged in energy-related businesses.

                                USE OF PROCEEDS

     We will not receive any proceeds from the exchange offer.

     We entered into a loan agreement, dated as of June 4, 1999, which we will
refer to as the "loan agreement", with several commercial banks and other
financial institutions, which provided for a 364-day term loan facility in an
amount up to $646.6 million, which we will refer to as the "term loan facility,"
and a 364-day revolving credit facility in an amount up to $40 million to
finance certain of our working capital needs, which we will refer to as the "old
working capital facility." We used the term loan facility to partially fund the
acquisition of our facilities (other than the Connecticut facilities). The
remainder of the purchase price for our facilities (other than the Connecticut
facilities) was funded with equity contributions from NRG Energy in the amount
of $353.6 million.

     The purchase price for the Connecticut facilities, which were acquired in
December 1999, was funded in part by equity contributions and in part by loans,
both made by NRG Energy.

     We used the proceeds from the sale of the outstanding bonds:

     - to repay all amounts of principal and interest outstanding under the term
       loan facility,

     - to pay our costs and expenses in connection with the offering of the
       bonds, and

     - to repay to NRG Energy money loaned in connection with the purchase of
       the Connecticut facilities.

     Contemporaneously with the closing of the issuance of the outstanding
bonds, we entered into a new $50 million revolving credit facility. At that
time, the loan agreement was terminated.

---------------

(a) On February 22, 2000, NRG Northeast issued $750 million of senior secured
    bonds. Approximately $646.6 million was used to repay short-term borrowings
    at December 31, 1999.



(b) Member's equity at June 30, 2000 reflects a net distribution of
    approximately $117.7 million. This net distribution consists primarily of
    the $95.8 million repayment of capital to NRG Energy and the payment of
    $21.4 million of proceeds received upon the termination of certain treasury
    locks to NRG Energy. The net distribution also includes the effect of
    removing the minority interest in NRG Northeast and other minor items. In
    addition to the net distribution described above, member's equity also
    included net income of $111.3 million.

                                  RISK FACTORS

     In addition to the information contained elsewhere in this prospectus, you
should carefully consider the following risk factors in evaluating the exchange
offer and an investment in the bonds.

YOU MAY HAVE DIFFICULTY SELLING THE OUTSTANDING BONDS THAT YOU DO NOT EXCHANGE.

     If you do not exchange your outstanding bonds for the bonds offered in this
exchange offer, you will continue to be subject to the restrictions on the
transfer of your bonds. Those transfer restrictions are described in the
indenture governing the bonds and in the legend contained on the outstanding
bonds, and arose because we originally issued the outstanding bonds under
exemptions from, and in transactions not subject to, the registration
requirements of the Securities Act.

     In general, you may offer or sell your outstanding bonds only if they are
registered under the Securities Act and applicable state securities laws, or if
they are offered and sold under an exemption from those requirements. We do not
intend to register the outstanding bonds under the Securities Act.

     If a large number of outstanding bonds are exchanged for bonds issued in
the exchange offer, it may be more difficult for you to sell your unexchanged
bonds. In addition, if you do not exchange your outstanding bonds in the
exchange offer, you will no longer be entitled to have those bonds registered
under the Securities Act.

     See "The Exchange Offer -- Consequences of Failure to Exchange Outstanding
Bonds" for a discussion of the possible consequences of failing to exchange your
bonds.

OUR REVENUES ARE NOT PREDICTABLE BECAUSE OUR POWER GENERATION FACILITIES
OPERATE, WHOLLY OR PARTIALLY, WITHOUT LONG-TERM POWER PURCHASE AGREEMENTS.

     Historically, substantially all revenues from independent power generation
facilities were derived under power purchase agreements having terms in excess
of 15 years, pursuant to which all energy and capacity was generally sold to a
single party at fixed prices. Because of changes in the industry, the number of
facilities with these types of long-term power purchase agreements has decreased
and is continuing to decrease. Our facilities currently operate without these
agreements. Without the benefit of these types of power purchase agreements, we
cannot assure you that we will be able to sell the power generated by our
facilities or that our facilities will be able to operate profitably.

BECAUSE WHOLESALE POWER PRICES ARE SUBJECT TO EXTREME VOLATILITY, THE REVENUES
THAT WE GENERATE ARE SUBJECT TO SIGNIFICANT FLUCTUATIONS.

     Except to the extent provided in the transition power sales contracts we
(through NRG Power Marketing) must sell all or a portion of the energy, capacity
and other products from our facilities into wholesale power markets. The prices
of energy products in those markets are influenced by many factors outside of
our control, including fuel prices, transmission constraints, supply and demand,
weather, economic conditions, and the rules, regulations and actions of the
system operators in those markets. In addition, unlike most other commodities,
energy products cannot be stored and therefore must be produced concurrently
with their use. As a result, the wholesale power markets are subject to
significant price fluctuations over relatively short periods of time and can be
unpredictable.

NRG POWER MARKETING HAS A LIMITED HISTORY OF SELLING AND MARKETING PRODUCTS IN
THE WHOLESALE POWER MARKETS AND MAY NOT BE ABLE TO SUCCESSFULLY MANAGE THE RISKS
ASSOCIATED WITH THIS ASPECT OF OUR BUSINESS.

     We are exposed to market risks through the activities on our behalf of our
power marketer, which involve the establishment of trading positions in the
energy, fuel and emission allowance markets on a short-term basis. Our power
marketer, NRG Power Marketing, sells forward contracts and options and
establishes positions in, and sells on the spot market, our energy, capacity and
other energy products that are not otherwise committed under long-term
contracts. In addition, NRG Power Marketing uses these trading activities to
procure fuel and emission allowances for our facilities on the spot market. NRG
Power Marketing
                                       17
<PAGE>   24


has been managing risks associated with price volatility in this manner for only
a limited period of time. It may not be able to effectively manage this price
volatility, and may not be able to successfully manage the other risks
associated with trading in energy markets, including the risk that counter
parties may not perform.


THE DAY-TO-DAY OPERATION OF POWER GENERATING FACILITIES INVOLVES OPERATIONAL
RISKS.

     Operation of our facilities involves many operating risks common to most
power generating facilities, including:

     - performance below expected levels of output or efficiency;

     - interruptions in fuel supply;

     - disruptions in the transmission of electricity;

     - breakdown or failure of equipment or processes;

     - violation of permit requirements; and

     - operator error or catastrophic events such as fires, earthquakes,
       explosions, floods or other similar occurrences affecting power
       generation facilities.

     In addition, although our facilities had a significant operating history at
the time we acquired them, we have a very limited history of owning and
operating these facilities and certain operational issues may arise as a result
of our lack of familiarity with issues specific to a particular facility or
component thereof or change in operating characteristics resulting from
regulation. A decrease or elimination of revenues generated by our facilities or
an increase in the costs of operating our facilities could decrease or eliminate
funds available to us to make payments on the bonds or our other obligations.

WE ARE EXPOSED TO THE RISK OF FUEL COST INCREASES AND INTERRUPTION IN FUEL
SUPPLY BECAUSE OUR FACILITIES GENERALLY DO NOT HAVE LONG-TERM FUEL SUPPLY
AGREEMENTS.

     Our facilities purchase fuel under short-term contracts or on the spot
market. Even though we attempt to hedge some portion of our known fuel
requirements, we still may face the risk of supply interruptions and fuel price
volatility. The price we can obtain for the sale of energy may not rise at the
same rate, or may not rise at all, to match a rise in fuel costs. This may have
a material adverse effect on our financial performance.

WE OFTEN RELY ON SINGLE SUPPLIERS AND AT TIMES WE RELY ON SINGLE CUSTOMERS AT
OUR FACILITIES, EXPOSING US TO SIGNIFICANT FINANCIAL RISKS IF EITHER SHOULD FAIL
TO PERFORM THEIR OBLIGATIONS.

     We often rely on a single supplier for the provision of fuel, water and
other services required for operation of a facility, and at times, we rely on a
single customer or a few customers to purchase all or a significant portion of a
facility's output. The failure of any one customer or supplier to fulfill its
contractual obligations to a facility could have a material adverse effect on
that facility's financial results. Consequently, the financial performance of
any such facility is dependent on the continued performance by customers and
suppliers of their obligations and, in particular, on the credit quality of the
project's customers and suppliers.

OUR BUSINESS IS SUBJECT TO SUBSTANTIAL GOVERNMENTAL REGULATION AND PERMITTING
REQUIREMENTS AND MAY BE ADVERSELY AFFECTED BY ANY FUTURE INABILITY TO COMPLY
WITH EXISTING REGULATIONS OR REQUIREMENTS OR CHANGES IN APPLICABLE REGULATIONS
OR REQUIREMENTS.

     In General.  Our business is subject to extensive energy, environmental and
other laws and regulations of federal, state and local authorities. We generally
are required to obtain and comply with a wide variety of licenses, permits and
other approvals in order to operate our facilities. We may incur significant
additional costs because of our compliance with these requirements. If we fail
to comply with these requirements, we could be subject to civil or criminal
liability and the imposition of liens or fines. In addition, existing
regulations may be revised or reinterpreted, new laws and regulations may be
adopted or become applicable to us or our facilities, and future changes in laws
and regulation may have a detrimental effect on our business.

                                       18
<PAGE>   25

Furthermore, with the continuing trend toward stricter standards, greater
regulation, more extensive permitting requirements and an increase in the assets
we operate, we expect our future environmental expenditures to be substantial.

     Energy Regulation.  The Public Utility Holding Company Act of 1935
("PUHCA") and the Federal Power Act ("FPA") regulate public utility holding
companies and their subsidiaries and place certain constraints on the conduct of
their business. The Energy Policy Act of 1992 provides relief from regulation
under PUHCA to exempt wholesale generators ("EWGs"). Maintaining the status of
our facilities as EWGs is conditioned on their continuing to meet statutory
criteria, and could be jeopardized, for example, by the making of retail sales
by an EWG in violation of the requirements of the Energy Policy Act. We are not
and will not be subject to regulation as a holding company under PUHCA as long
as the power plants we own are EWGs.

     We are continually in the process of obtaining or renewing federal, state
and local approvals required to operate our facilities. Additional regulatory
approvals may be required in the future due to a change in laws and regulations,
a change in our customers or other reasons. We may not always be able to obtain
all required regulatory approvals, and we may not be able to obtain any
necessary modifications to existing regulatory approvals or maintain all
required regulatory approvals. If there is a delay in obtaining any required
regulatory approvals or if we fail to obtain and comply with any required
regulatory approvals, the operation of our facilities or the sale of electricity
to third parties could be prevented or subject to additional costs.

     Environmental Regulation.  In acquiring our facilities, we assumed, subject
to certain exceptions, all on-site liabilities associated with the environmental
condition of our facilities, regardless of when such liabilities arose and
whether known or unknown, and generally agreed to indemnify the former owners of
those facilities for on-site environmental liabilities. We may not at all times
be in compliance with all applicable environmental laws and regulations. Steps
to bring our facilities into compliance could be prohibitively expensive, and
may cause us to be unable to pay our debts when due. Moreover, environmental
laws and regulations can change.


     For example, on October 14, 1999, Governor Pataki of New York announced
that he was ordering the New York Department of Environmental Conservation to
require further reductions of sulphur dioxide and nitrogen oxides emissions from
New York power plants, beyond that which is required under current federal and
state law. These reductions would be phased in between January 1, 2003 and
January 1, 2007. The New York Department of Environmental Conservation is
currently working on draft regulations to implement Governor Pataki's
initiative. Compliance with these emission reductions requirements, if they
become effective, could have a material adverse impact on the operation of some
of our facilities located in the State of New York.



     On May 17, 2000, Governor Rowland of Connecticut issued an Executive Order
to the Connecticut Department of Environmental Protection ("CDEP") that requires
the CDEP to develop regulations, applicable to power plants and other major
sources of air pollution, to further reduce emissions of nitrogen oxides and
sulphur dioxides by May 2003. The Executive Order requires reductions of sulphur
dioxides by an amount that is 30% to 50% greater than current commitments and
reductions of nitrogen oxides that are 20% to 30% greater than current
commitments. The Executive Order provides that the CDEP should use market based
incentives and a system of creditable emissions allowances or credits to foster
cost effective reductions. In August 2000, the CDEP issued proposed regulations
to implement the Executive Order. Although we are actively participating in the
CDEP's rulemaking process, there is no assurance that our positions will be
adopted. See "Business of NRG Northeast and the Guarantors -- Environmental
Matters."



     The Commonwealth of Massachusetts is also seeking additional emissions
reductions beyond current requirements. The Massachusetts Department of
Environmental Protection has issued proposed regulations that would require
significant emissions reductions from certain coal-fired power plants in the
state, including our Somerset facility. The Massachusetts Department of
Environmental Protection has proposed that such facilities comply with stringent
limits on emissions of nitrogen oxides by December 1, 2003; on emissions of
sulfur dioxides commencing on December 1, 2003, with further reductions required
by December 1, 2005; and on emissions of carbon dioxide by December 1, 2005. In
addition to output-based limits (that is, a standard

                                       19
<PAGE>   26


which limits emissions to a certain rate per net megawatt hour), the proposed
regulations also would limit, by December 1, 2003, the total emissions of
nitrogen oxides and sulfur dioxide at the Somerset facility to no more than 75%
of the average annual emissions of the Somerset facility for the years
1997 - 1999. Finally, the proposed regulations require the Massachusetts
Department of Environmental Protection to evaluate, by December 1, 2002, the
technological and economic feasibility of controlling or eliminating mercury
emissions by the year 2010, and to propose mercury emission standards within 18
months of completion of the feasibility evaluation. Compliance with these
proposed regulations, if such regulations become effective, could have a
material impact on the operation of our Somerset facility. The annual average
carbon dioxide emission rate identified in the proposed regulations cannot be
met by the Somerset facility.



     Finally, the Speaker of the New York City Council and other members of the
Council have introduced legislation that will require an agency designated by
the Mayor to establish an emissions standard for carbon dioxide that is no
greater than the emissions of carbon dioxide from electric generating units
(with a capacity of more than 25 megawatts) located in the City of New York in
1999 divided by the electricity generated in the same year by said units. The
proposed law would require the standard to be reduced, each year, by one percent
for each one hundred megawatts of electric generating capacity installed within
the City of New York during the previous calendar year, until the carbon dioxide
emission standard has been reduced by 30%. The proposed law requires that the
initial carbon dioxide emission standard be established by March 1, 2002.
Although the proposed law, if enacted, could have an impact on the operation of
our Arthur Kill facility and on certain of our Astoria peaking units, we believe
that we are in a better position to comply with this proposed law than many
other generating units located in the New York City market.


     The New York Department of Environmental Conservation recently issued a
Notice of Violation to us and the prior owner of our Huntley and Dunkirk
facilities relating to physical changes made at those facilities prior to our
assumption of ownership. The Notice of Violation alleges that these changes
represent major modifications undertaken without obtaining the required permits.
Although we have a right to indemnification by the previous owner for fines,
penalties, assessments, and related losses resulting from the previous owner's
failure to comply with environmental laws and regulations, if these facilities
did not comply with the applicable permit requirements, we could be required,
among other things, to install specified pollution control technology to further
reduce air emissions from the Dunkirk and Huntley facilities and we could become
subject to fines and penalties associated with the current and prior operation
of the facilities. See "Business -- Legal Proceedings."

     In addition, on November 3, 1999, the United States Department of Justice
filed suit against seven electric utilities for alleged violations of Clean Air
Act requirements related to modifications of existing sources at seventeen
utility generation stations located in the southern and midwestern regions of
the United States. The EPA also issued administrative notices of violation
alleging similar violations at eight other power plants owned by some of the
electric utilities named as defendants in the lawsuit, and also issued an
administrative order to the Tennessee Valley Authority for similar violations at
seven of its power plants. Other than the Notice of Violation issued to the
Huntley and Dunkirk facilities, no lawsuits or administrative actions have been
brought against us or any of our subsidiaries or affiliates or the former owners
of our facilities alleging similar violations. Lawsuits or administrative
actions alleging similar violations at our facilities could be filed in the
future and if successful, could have a material adverse effect on our business.

OUR COMPETITION IS INCREASING.

     The independent power industry is characterized by numerous strong and
capable competitors, some of which may have more extensive operating experience,
more extensive experience in the acquisition and development of power generation
facilities or greater financial resources than we do.

     In addition, regulatory changes have also been proposed to increase access
to transmission grids by utility and non-utility purchasers and sellers of
electricity. Industry deregulation may encourage the disaggregation of
vertically integrated utilities into separate generation, transmission and
distribution businesses. As a result, significant additional competitors could
become active in the generation segment of our industry.

                                       20

WE FACE ONGOING CHANGES IN THE UNITED STATES UTILITY INDUSTRY THAT COULD AFFECT
OUR COMPETITIVENESS.

     The United States electric utility industry is currently experiencing
increasing competitive pressures, primarily in wholesale markets, as a result of
consumer demands, technological advances, greater availability of natural
gas-fired generation that is more efficient than our generation facilities and
other factors. FERC has implemented and continues to propose regulatory changes
to increase access to the nationwide transmission grid by utility and
non-utility purchasers and sellers of electricity. In addition, a number of
states are considering or implementing methods to introduce and promote retail
competition.

     Proposals have been introduced in Congress to repeal PUHCA, and FERC has
publicly indicated support for the PUHCA repeal effort. If the repeal of PUHCA
occurs, either separately or as part of legislation designed to encourage the
broader introduction of wholesale and retail competition, the significant
competitive advantages that independent power producers currently enjoy over
certain regulated utility companies would be eliminated or sharply curtailed,
and the ability of regulated utility companies to compete more directly with
independent power companies would be increased. To the extent competitive
pressures increase and the pricing and sale of electricity assumes more
characteristics of a commodity business, the economics of domestic independent
power generation projects may come under increasing pressure. Deregulation may
not only continue to fuel the current trend toward consolidation among domestic
utilities, but may also encourage the disaggregation of vertically-integrated
utilities into separate generation, transmission and distribution businesses.


     In addition, the independent system operators who oversee most of the
wholesale power markets have in the past imposed, and may in the future continue
to impose, price limitations and other mechanisms to address some of the
volatility in these markets. For example, on May 31, 2000, FERC approved a
request of the independent system operator for the NYPP, which we will refer to
in this prospectus as the NY ISO, to impose price limitations on one ancillary
service, Ten Minute Non-synchronized Reserves, on a prospective basis only,
effective March 28, 2000, the date the NY ISO began capping bids for the
service. FERC rejected the NY ISO's request for authority to adjust the
market-clearing prices for that service on a retroactive basis. On June 30, 2000
the NY ISO sought reconsideration of this order. As a result of the FERC's order
(unless the NY ISO or other party successfully appeals the order) we will retain
approximately $8.0 million of revenues collected in February 2000 and
approximately $8.2 million included in revenues, but not yet collected, for
March 2000. If our positions do not prevail, our revenues from ancillary
services sold in the NYPP could be substantially reduced.


     These types of price limitations and other mechanisms in New York and
elsewhere may adversely impact the profitability of our generation facilities
that sell energy into the wholesale power markets. Given the extreme volatility
and lack of meaningful long-term price history in many of these markets and the
imposition of price limitations by independent system operators, we can offer no
assurance that we will be able to operate profitably in all wholesale power
markets.

WE RELY ON OUR CONTRACTUAL ARRANGEMENTS WITH NRG ENERGY AND ITS AFFILIATES TO
CONDUCT OUR BUSINESS.

     We currently have no employees of our own and, accordingly, are dependent
on contractual arrangements with NRG Energy, NRG Power Marketing and
subsidiaries of NRG Operating Services to conduct our business. We are not
certain that we could easily replace any of these contractual arrangements with
a third party on substantially similar terms if any existing arrangement were to
be terminated. In addition, in the event the other contracting party performed
its obligations in a manner which resulted in a loss to us, our possible
remedies and indemnities under these agreements may not make us completely whole
due to limitations on liability provided by these contractual arrangements. Thus
the risk of poor performance by any of these contracting parties could be borne
by us under certain circumstances.


WE DEPEND ON AND ARE CONTROLLED BY NRG ENERGY AND XCEL ENERGY.



     NRG Energy indirectly owns 100% of the equity interest in NRG Northeast,
and in turn Xcel Energy indirectly owns approximately 82% of the stock
outstanding and 98% of the combined voting power of NRG Energy's common stock
and class A common stock. In circumstances involving a conflict of interest
between

                                       21
<PAGE>   28


NRG Energy, Xcel Energy or their affiliates, on the one hand, and our creditors,
on the other, we cannot guarantee that NRG Energy or Xcel Energy would not
exercise its power to control us in a manner that would benefit NRG Energy, Xcel
Energy and their affiliates to the detriment of the holders of the bonds.
Moreover, we cannot guarantee that NRG Energy or Xcel Energy will not in the
future elect to compete with us, directly or indirectly, including by acquiring
electrical generation assets which sell energy, capacity and/or ancillary
services into the NYPP and/or the NEPOOL.


WE ARE UNCERTAIN ABOUT OUR FUTURE ACCESS TO CAPITAL.


     To date, the capital for the acquisition of our facilities has been
provided by equity contributions from NRG Energy and certain borrowings. We
cannot guarantee that we will be successful in obtaining sufficient additional
capital from NRG Energy or additional borrowings at favorable interest rates to
enable us to fund all of our future capital requirements.


WE MAY INCUR ADDITIONAL DEBT WHICH COULD ADVERSELY AFFECT YOU.

     Subject to the indenture, we may incur additional debt, including
additional series of bonds, to pay for certain capital improvements and
expansions of our facilities, to refinance existing indebtedness and to make
additional distributions to our owners. Certain types of this permitted
indebtedness may rank equally with the bonds and share in the collateral
package.

THE INSURANCE COVERAGE FOR OUR FACILITIES MAY NOT BE ADEQUATE TO COVER POTENTIAL
LIABILITIES AND LOSSES.

     We are required by the indenture to have insurance for our facilities in
amounts and against risks as are customarily maintained by companies engaged in
the same or similar operations operating in the same or similar locations. We
cannot guarantee that such insurance coverage for our facilities will be
available in the future on commercially reasonable terms.

WE ARE THE ONLY ONES REQUIRED TO MAKE PAYMENTS ON THE BONDS AND OUR ABILITY TO
DO SO IS DEPENDENT ON CIRCUMSTANCES BEYOND OUR CONTROL.


     None of our affiliates, members or officers will be required to make
payments on the bonds, including NRG Energy and Xcel Energy (other than the
guarantors, and NRG Energy under any debt service reserve support instrument
issued in respect of our debt service reserve requirements). NRG Northeast is a
holding company and its only significant assets are its equity interests in the
guarantors. Our ability to make payments on the bonds (including prepayment
obligations triggered by specific kinds of change of control events which we
cannot necessarily control) is dependent on the ability of the guarantors to
make current payments on the intercompany notes and/or make equity
distributions.


YOU MAY FIND IT DIFFICULT TO SELL YOUR BONDS BECAUSE THERE IS NO EXISTING
TRADING MARKET FOR THE BONDS.

     You may find it difficult to sell your bonds because an active trading
market for the bonds may not develop. The bonds are being offered to the holders
of the outstanding bonds. The outstanding bonds were issued on February 22,
2000, primarily to a small number of institutional investors and overseas
investors. After the exchange offer, the trading market for the remaining
untendered outstanding bonds could be adversely affected.


     There is no existing trading market for the bonds. We do not intend to
apply for listing or quotation of the bonds on any exchange. Therefore, we do
not know the extent to which investor interest will lead to the development of a
trading market or how liquid that market might be. Although the initial
purchasers of the outstanding bonds have informed us that they currently intend
to make a market in the bonds, they are not required to do so, and they may
cease market-making at any time without notice. As a result, the market price of
the bonds issued in this exchange offer could be adversely affected.


                                       22
<PAGE>   29

FEDERAL AND STATE STATUTES ALLOW COURTS, UNDER SPECIFIC CIRCUMSTANCES, TO VOID
SUBSIDIARY GUARANTEES AND REQUIRE HOLDERS OF BONDS TO RETURN PAYMENTS RECEIVED
FROM GUARANTORS.

     Under the federal bankruptcy law and comparable provisions of state
fraudulent transfer laws, the guarantees by the guarantors of the bonds could be
voided, or claims in respect thereof could be subordinated to all other debts of
a guarantor, if, among other things, the guarantor, at the time it incurred the
indebtedness evidenced by its guarantee:

     - received less than fair consideration or reasonably equivalent value for
       the guarantee;

     - was insolvent or rendered insolvent by reason of such issuance;

     - was engaged in a business or transaction for which its remaining assets
       constituted unreasonably small capital; or

     - intended to incur, or believed that it would incur, debts beyond its
       ability to pay such debts as they mature.

     In addition, any payment by a guarantor pursuant to its guarantee could be
voided and required to be returned to that guarantor, or to a fund for the
benefit of the creditors of such guarantor. The guarantors' liabilities under
their guarantees are contractually limited to the maximum amount they could pay
without the guarantees being deemed to be fraudulent transfers. We cannot
guarantee, however, that this limitation would be effective and, if it were
effective, if the limited amount would be sufficient to pay the bonds in full.

IT MAY BE DIFFICULT TO REALIZE THE VALUE OF THE COLLATERAL PLEDGED TO SECURE THE
BONDS, AND THE PROCEEDS RECEIVED FROM A SALE OF THE COLLATERAL MAY BE
INSUFFICIENT TO REPAY THE BONDS.

     Our obligation to make payments on the bonds is secured only by the
collateral described in this prospectus and, specifically, does not include a
lien on the physical assets comprising our facilities. The collateral agent's
ability to foreclose on the collateral on your behalf may be subject to
perfection and priority issues and to practical problems associated with the
realization of the collateral agent's security interest in the collateral. For
example, the collateral agent may need to obtain the consent of a third party
prior to transferring a contract. We cannot assure you that the collateral agent
will be able to obtain such consent. Further, we cannot assure you that
enforcement of the security interest with respect to the collateral would
provide sufficient funds to repay all amounts due on the bonds.

                               THE EXCHANGE OFFER

PURPOSE OF THE EXCHANGE OFFER


     When we sold the outstanding bonds on February 22, 2000, we entered into a
registration rights agreement with the initial purchasers of those bonds. Under
the registration rights agreement, we agreed to use our reasonable best efforts
to file the registration statement of which this prospectus forms a part
regarding the exchange of the outstanding bonds for bonds which are registered
under the Securities Act and cause this registration statement to be declared
effective by the SEC by November 20, 2000. We also agreed to conduct this
exchange offer for at least 30 days after the date notice of the exchange offer
is mailed to the holders of the outstanding bonds. We will use our best efforts
to keep this registration statement effective until the exchange offer is
completed. The registration rights agreement provides that we will be required
to pay liquidated damages to the holders of the outstanding bonds if:


     - the registration statement is not declared effective by November 20,
       2000; or

     - the exchange offer has not been consummated by January 3, 2001.


     A copy of the registration rights agreement is filed as an exhibit to the
registration statement of which this prospectus forms a part.


TERMS OF THE EXCHANGE OFFER


     This prospectus and the accompanying letter of transmittal together
constitute the exchange offer. Upon the terms and subject to the conditions set
forth in this prospectus and in the letter of transmittal, we will accept for
exchange outstanding bonds which are properly tendered on or before the
expiration date and are not withdrawn as permitted below. The expiration date
for this exchange offer is 5:00 p.m., New York City time, on November 27, 2000,
or such later date and time to which we, in our sole discretion, extend the
exchange offer.


     The form and terms of the bonds being issued in the exchange offer are the
same as the form and terms of the outstanding bonds, except that:

     - the bonds being issued in the exchange offer will have been registered
       under the Securities Act;

     - the bonds issued in the exchange offer will not bear the restrictive
       legends restricting their transfer under the Securities Act; and

     - the bonds being issued in the exchange offer will not contain the
       registration rights and liquidated damages provisions contained in the
       outstanding bonds.


     Bonds tendered in the exchange offer must be in denominations of the
principal amount of $100,000 or any integral multiples of $1,000 in excess of
$100,000.


     We expressly reserve the right, in our sole discretion:

     - to extend the expiration date;

     - to delay accepting any outstanding bonds;

     - if any of the conditions set forth below under "-- Conditions to the
       Exchange Offer" have not been satisfied, to terminate the exchange offer
       and not accept any bonds for exchange; and

     - to amend the exchange offer in any manner.

     We will give oral or written notice of any extension, delay,
non-acceptance, termination or amendment as promptly as practicable by a public
announcement, and in the case of an extension, no later than 9:00 a.m., New York
City time, on the next business day after the previously scheduled expiration
date.

     During an extension, all outstanding bonds previously tendered will remain
subject to the exchange offer and may be accepted for exchange by us. Any
outstanding bonds not accepted for exchange for any reason will

                                       24
<PAGE>   31

be returned without cost to the holder that tendered them as promptly as
practicable after the expiration or termination of the exchange offer.

HOW TO TENDER OUTSTANDING BONDS FOR EXCHANGE

     When the holder of outstanding bonds tenders, and we accept, bonds for
exchange, a binding agreement between us and the tendering holder is created,
subject to the terms and conditions set forth in this prospectus and the
accompanying letter of transmittal. Except as set forth below, a holder of
outstanding bonds who wishes to tender bonds for exchange must, on or prior to
the expiration date:

          (1) transmit a properly completed and duly executed letter of
     transmittal, including all other documents required by such letter of
     transmittal, to The Chase Manhattan Bank (the "exchange agent") at the
     address set forth below under the heading "-- The Exchange Agent"; or

          (2) if bonds are tendered pursuant to the book-entry procedures set
     forth below, the tendering holder must transmit an agent's message to the
     exchange agent at the address set forth below under the heading "-- The
     Exchange Agent."

     In addition, either:

          (1) the exchange agent must receive the certificates for the
     outstanding bonds and the letter of transmittal;

          (2) the exchange agent must receive, prior to the expiration date, a
     timely confirmation of the book-entry transfer of the bonds being tendered
     into the exchange agent's account at the Depository Trust Company ("DTC")
     along with the letter of transmittal or an agent's message; or

          (3) the holder must comply with the guaranteed delivery procedures
     described below.

     The term "agent's message" means a message, transmitted to DTC and received
by the exchange agent and forming a part of a book-entry transfer (a "book-entry
confirmation"), which states that DTC has received an express acknowledgment
that the tendering holder agrees to be bound by the letter of transmittal and
that we may enforce the letter of transmittal against such holder.

     The method of delivery of the outstanding bonds, the letters of transmittal
and all other required documents is at the election and risk of the holders. If
such delivery is by mail, we recommend registered mail, properly insured, with
return receipt requested. In all cases, you should allow sufficient time to
assure timely delivery. No letters of transmittal or bonds should be sent
directly to us.

     Signatures on a letter of transmittal or a notice of withdrawal, as the
case may be, must be guaranteed unless the bonds surrendered for exchange are
tendered:

          (1) by a holder of outstanding bonds who has not completed the box
     entitled "Special Issuance Instructions" or "Special Delivery Instructions"
     on the letter of transmittal; or

          (2) for the account of an eligible institution.

     An "eligible institution" is a firm which is a member of a registered
national securities exchange or a member of the National Association of
Securities Dealers, Inc., or a commercial bank or trust company having an office
or correspondent in the United States.

     If signatures on a letter of transmittal or notice of withdrawal are
required to be guaranteed, the guarantor must be an eligible institution. If
bonds are registered in the name of a person other than the signer of the letter
of transmittal, the bonds surrendered for exchange must be endorsed by, or
accompanied by a written instrument or instruments of transfer or exchange, in
satisfactory form as determined by us in our sole discretion, duly executed by
the registered holder with the holder's signature guaranteed by an eligible
institution.

                                       25
<PAGE>   32

     We will determine all questions as to the validity, form, eligibility
(including time of receipt) and acceptance of bonds tendered for exchange in our
sole discretion. Our determination will be final and binding. We reserve the
absolute right to:

          (1) reject any and all tenders of any bond improperly tendered;

          (2) refuse to accept any bond if, in our judgment or the judgment of
     our counsel, acceptance of the bond may be deemed unlawful; and

          (3) waive any defects or irregularities or conditions of the exchange
     offer as to any particular bond either before or after the expiration date,
     including the right to waive the ineligibility of any holder who seeks to
     tender bonds in the exchange offer.

     Our interpretation of the terms and conditions of the exchange offer as to
any particular bonds either before or after the expiration date, including the
letter of transmittal and the instructions to it, will be final and binding on
all parties. Holders must cure any defects and irregularities in connection with
tenders of bonds for exchange within such reasonable period of time as we will
determine, unless we waive such defects or irregularities. Neither we, the
exchange agent nor any other person will be under any duty to give notification
of any defect or irregularity with respect to any tender of bonds for exchange,
nor will any of us incur any liability for failure to give such notification.

     If a person or persons other than the registered holder or holders of the
outstanding bonds tendered for exchange signs the letter of transmittal, the
tendered bonds must be endorsed or accompanied by appropriate powers of
attorney, in either case signed exactly as the name or names of the registered
holder or holders that appear on the outstanding bonds.

     If trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity sign the letter of transmittal or any bonds or any power of attorney,
such persons should so indicate when signing, and you must submit proper
evidence satisfactory to us of such person's authority to so act unless we waive
this requirement.

     By tendering, each holder will represent to us that, among other things,
the person acquiring bonds in the exchange offer is obtaining them in the
ordinary course of its business, whether or not such person is the holder, and
that neither the holder nor such other person has any arrangement or
understanding with any person to participate in the distribution of the bonds
issued in the exchange offer. If any holder or any such other person is an
"affiliate," as defined under Rule 405 of the Securities Act, of our company, or
is engaged in or intends to engage in or has an arrangement or understanding
with any person to participate in a distribution of such bonds to be acquired in
the exchange offer, such holder or any such other person:

          (1) may not rely on the applicable interpretations of the staff of the
     SEC; and

          (2) must comply with the registration and prospectus delivery
     requirements of the Securities Act in connection with any resale
     transaction.

     Each broker-dealer who acquired its outstanding bonds as a result of
market-making activities or other trading activities and thereafter receives
bonds issued for its own account in the exchange offer, must acknowledge that it
will deliver a prospectus in connection with any resale of such bonds issued in
the exchange offer. The letter of transmittal states that by so acknowledging
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act. See "Plan of
Distribution" for a discussion of the exchange and resale obligations of
broker-dealers in connection with the exchange offer.

ACCEPTANCE OF OUTSTANDING BONDS FOR EXCHANGE; DELIVERY OF BONDS ISSUED IN THE
EXCHANGE OFFER

     Upon satisfaction or waiver of all of the conditions to the exchange offer,
we will accept, promptly after the expiration date, all outstanding bonds
properly tendered and will issue bonds registered under the Securities Act. For
purposes of the exchange offer, we will be deemed to have accepted properly
tendered outstanding bonds for exchange when, as and if we have given oral or
written notice to the exchange agent,

                                       26
<PAGE>   33

with written confirmation of any oral notice to be given promptly thereafter.
See "-- Conditions to the Exchange Offer" for a discussion of the conditions
that must be satisfied before we accept any bonds for exchange.

     For each outstanding bond accepted for exchange, the holder will receive a
bond registered under the Securities Act having a principal amount equal to, and
in the denomination of, that of the surrendered outstanding bond. Accordingly,
registered holders of bonds issued in the exchange offer on the relevant record
date for the first interest payment date following the consummation of the
exchange offer will receive interest accruing from the most recent date to which
interest has been paid or, if no interest has been paid on the outstanding
bonds, from February 22, 2000. Outstanding bonds that we accept for exchange
will cease to accrue interest from and after the date of consummation of the
exchange offer. Under the registration rights agreement, we may be required to
make additional payments in the form of liquidated damages to the holders of the
outstanding bonds under circumstances relating to the timing of the exchange
offer.

     In all cases, we will issue bonds in the exchange offer for outstanding
bonds that are accepted for exchange only after the exchange agent timely
receives:

          (1) certificates for such outstanding bonds or a timely book-entry
     confirmation of such outstanding bonds into the exchange agent's account at
     DTC;

          (2) a properly completed and duly executed letter of transmittal or an
     agent's message; and

          (3) all other required documents.

     If for any reason set forth in the terms and conditions of the exchange
offer we do not accept any tendered outstanding bonds, or if a holder submits
outstanding bonds for a greater principal amount than the holder desires to
exchange, we will return such unaccepted or non-exchanged bonds without cost to
the tendering holder. In the case of bonds tendered by book-entry transfer into
the exchange agent's account at DTC such non-exchanged bonds will be credited to
an account maintained with DTC. We will return the bonds or have them credited
to DTC as promptly as practicable after the expiration or termination of the
exchange offer.

BOOK ENTRY TRANSFERS

     The exchange agent will make a request to establish an account at DTC for
purposes of the exchange offer within two (2) business days after the date of
this prospectus. Any financial institution that is a participant in DTC's system
must make book-entry delivery of outstanding bonds denominated in dollars by
causing DTC to transfer the outstanding bonds into the exchange agent's account
at DTC in accordance with DTC's procedures for transfer. Such participant should
transmit its acceptance to DTC on or prior to the expiration date or comply with
the guaranteed delivery procedures described below. DTC will verify such
acceptance, execute a book-entry transfer of the tendered outstanding bonds into
the exchange agent's account at DTC and then send to the exchange agent
confirmation of such book-entry transfer. The confirmation of such book-entry
transfer will include an agent's message confirming that DTC has received an
express acknowledgment from such participant that such participant has received
and agrees to be bound by the letter of transmittal and that we may enforce the
letter of transmittal against such participant. Delivery of bonds issued in the
exchange offer may be effected through book-entry transfer at DTC as applicable.
However, the letter of transmittal or facsimile thereof or an agent's message,
with any required signature guarantees and any other required documents, must:

          (1) be transmitted to and received by the exchange agent at the
     address set forth below under "-- Exchange Agent" on or prior to the
     expiration date; or

          (2) comply with the guaranteed delivery procedures described below.

GUARANTEED DELIVERY PROCEDURES

     If a holder of outstanding bonds desires to tender such bonds and the
holder's bonds are not immediately available, or time will not permit such
holder's bonds or other required documents to reach the exchange agent

                                       27
<PAGE>   34

before the expiration date, or the procedure for book-entry transfer cannot be
completed on a timely basis, a tender may be effected if:

          (1) the holder tenders the bonds through an eligible institution;

          (2) prior to the expiration date, the exchange agent receives from
     such eligible institution a properly completed and duly executed notice of
     guaranteed delivery, substantially in the form we have provided, by
     telegram, telex, facsimile transmission, mail or hand delivery, setting
     forth the name and address of the holder of the bonds being tendered and
     the amount of the bonds being tendered. The notice of guaranteed delivery
     will state that the tender is being made and guarantee that within three
     (3) New York Stock Exchange trading days after the date of execution of the
     notice of guaranteed delivery, the certificates for all physically tendered
     bonds, in proper form for transfer, or a book-entry confirmation, as the
     case may be, together with a properly completed and duly executed letter of
     transmittal or agent's message with any required signature guarantees and
     any other documents required by the letter of transmittal will be deposited
     by the eligible institution with the exchange agent; and

          (3) the exchange agent receives the certificates for all physically
     tendered outstanding bonds, in proper form for transfer, or a book-entry
     confirmation, as the case may be, together with a properly completed and
     duly executed letter of transmittal or agent's message with any required
     signature guarantees and any other documents required by the letter of
     transmittal, within three (3) New York Stock Exchange trading days after
     the date of execution of the notice of guaranteed delivery.

WITHDRAWAL RIGHTS

     You may withdraw tenders of your outstanding bonds at any time prior to
5:00 p.m., New York City time, on the expiration date.

     For a withdrawal to be effective, you must send a written notice of
withdrawal to the exchange agent at one of the addresses set forth below under
"-- Exchange Agent." Any such notice of withdrawal must:

          (1) specify the name of the person having tendered the outstanding
     bonds to be withdrawn;

          (2) identify the outstanding bonds to be withdrawn, including the
     principal amount of such outstanding bonds; and

          (3) where certificates for outstanding bonds are transmitted, specify
     the name in which outstanding bonds are registered, if different from that
     of the withdrawing holder.

     If certificates for outstanding bonds have been delivered or otherwise
identified to the exchange agent, then, prior to the release of such
certificates the withdrawing holder must also submit the serial numbers of the
particular certificates to be withdrawn and signed notice of withdrawal with
signatures guaranteed by an eligible institution unless such holder is an
eligible institution. If bonds have been tendered pursuant to the procedure for
book-entry transfer described above, any notice of withdrawal must specify the
name and number of the account at DTC to be credited with the withdrawn bonds
and otherwise comply with the procedures of such facility. We will determine all
questions as to the validity, form and eligibility (including time of receipt)
of such notices and our determination will be final and binding on all parties.
Any tendered bonds so withdrawn will be deemed not to have been validly tendered
for exchange for purposes of the exchange offer. Any bonds which have been
tendered for exchange but which are not exchanged for any reason will be
returned to the holder thereof without cost to such holder. In the case of bonds
tendered by book-entry transfer into the exchange agent's account at DTC, the
bonds withdrawn will be credited to an account maintained with DTC for the
outstanding bonds. The bonds will be returned or credited to DTC account as soon
as practicable after withdrawal, rejection of tender or termination of the
exchange offer. Properly withdrawn bonds may be re-tendered by following one of

CONDITIONS TO THE EXCHANGE OFFER

     We are not required to accept for exchange, or to issue bonds in the
exchange offer for any outstanding bonds. We may terminate or amend the exchange
offer, if at any time before the acceptance of such outstanding bonds for
exchange:

          (1) any federal law, statute, rule or regulation will have been
     adopted or enacted which, in our judgment, would reasonably be expected to
     impair our ability to proceed with the exchange offer;

          (2) any stop order will be threatened or in effect with respect to the
     registration statement of which this prospectus constitutes a part or the
     qualification of the indenture under the Trust Indenture Act of 1939, as
     amended;

          (3) there will occur a change in the current interpretation by staff
     of the SEC which permits the bonds issued in the exchange offer in exchange
     for the outstanding bonds to be offered for resale, resold and otherwise
     transferred by such holders, other than broker-dealers and any such holder
     which is an "affiliate" of our company within the meaning of Rule 405 under
     the Securities Act, without compliance with the registration and prospectus
     delivery provisions of the Securities Act, provided that such bonds
     acquired in the exchange offer are acquired in the ordinary course of such
     holder's business and such holder has no arrangement or understanding with
     any person to participate in the distribution of such bonds issued in the
     exchange offer;

          (4) there has occurred any general suspension of or general limitation
     on prices for, or trading in, securities on any national exchange or in the
     over-the-counter market;

          (5) any governmental agency creates limits that adversely affect our
     ability to complete the exchange offer;

          (6) there will occur any declaration of war, armed hostilities or
     other similar international calamity directly or indirectly involving the
     United States, or the worsening of any such condition that existed at the
     time that we commence the exchange offer;

          (7) there will have occurred a change (or a development involving a
     prospective change) in our and our subsidiaries' businesses, properties,
     assets, liabilities, financial condition, operations, results of operations
     taken as a whole, that is or may be adverse to us; or

          (8) we will have become aware of facts that, in our reasonable
     judgment, have or may have adverse significance with respect to the value
     of the outstanding bonds or the bonds to be issued in the exchange offer.

     The preceding conditions are for our sole benefit and we may assert them
regardless of the circumstances giving rise to any such condition. We may waive
the preceding conditions in whole or in part at any time and from time to time
in our sole discretion. If we do so, the exchange offer will remain open for at
least three (3) business days following any waiver of the preceding conditions.
Our failure at any time to exercise the foregoing rights will not be deemed a
waiver of any such right and each such right will be deemed an ongoing right
which we may assert at any time and from time to time.

     The Chase Manhattan Bank has been appointed as our exchange agent for the
exchange offer. All executed letters of transmittal should be directed to our

     Delivery of the letter of transmittal to an address other than as set forth
above or transmission of such letter of transmittal via facsimile other than as
set forth above does not constitute a valid delivery of such letter of
transmittal.

FEES AND EXPENSES

     We will not make any payment to brokers, dealers, or others soliciting
acceptance of the exchange offer except for reimbursement of mailing expenses.

     The estimated cash expenses to be incurred in connection with the exchange
offer will be paid by us and are estimated in the aggregate to be approximately
$500,000.

TRANSFER TAXES

     Holders who tender their outstanding bonds for exchange will not be
obligated to pay any transfer taxes in connection with the exchange. If,
however, bonds issued in the exchange offer are to be delivered to, or are to be
issued in the name of, any person other than the holder of the bonds tendered,
or if a transfer tax is imposed for any reason other than the exchange of
outstanding bonds in connection with the exchange offer, then the holder must
pay any such transfer taxes, whether imposed on the registered holder or on any
other person. If satisfactory evidence of payment of, or exemption from, such
taxes is not submitted with the letter of transmittal, the amount of such
transfer taxes will be billed directly to the tendering holder.

CONSEQUENCES OF FAILURE TO EXCHANGE OUTSTANDING BONDS

     Holders who desire to tender their outstanding bonds in exchange for bonds
registered under the Securities Act should allow sufficient time to ensure
timely delivery. Neither the exchange agent nor our company is under any duty to
give notification of defects or irregularities with respect to the tenders of
bonds for exchange.


     Outstanding bonds that are not tendered or are tendered but not accepted
will, following the consummation of the exchange offer, continue to be subject
to the provisions in the indenture regarding the transfer and exchange of the
outstanding bonds and the existing restrictions on transfer set forth in the
legend on the outstanding bonds and in the offering circular dated February 15,
2000, relating to the outstanding bonds. Except in limited circumstances with
respect to specific types of holders of outstanding bonds, we will have no


                                       30
<PAGE>   37

further obligation to provide for the registration under the Securities Act of
such outstanding bonds. In general, outstanding bonds, unless registered under
the Securities Act, may not be offered or sold except pursuant to an exemption
from, or in a transaction not subject to, the Securities Act and applicable
state securities laws. We do not currently anticipate that we will take any
action to register the outstanding bonds under the Securities Act or under any
state securities laws.

     Upon completion of the exchange offer, holders of the outstanding bonds
will not be entitled to any further registration rights under the registration
rights agreement, except under limited circumstances.

     Holders of the bonds issued in the exchange offer and any outstanding bonds
which remain outstanding after consummation of the exchange offer will vote
together as a single class for purposes of determining whether holders of the
requisite percentage of the class have taken certain actions or exercised
certain rights under the indenture.

CONSEQUENCES OF EXCHANGING OUTSTANDING BONDS

     Based on interpretations of the staff of the SEC, as set forth in no-action
letters to third parties, we believe that the bonds issued in the exchange offer
may be offered for resale, resold or otherwise transferred by holders of those
bonds, other than by any holder which is an "affiliate" of our company within
the meaning of Rule 405 under the Securities Act. The bonds may be offered for
resale, resold or otherwise transferred without compliance with the registration
and prospectus delivery provisions of the Securities Act, if:

          (1) the bonds issued in the exchange offer are acquired in the
     ordinary course of such holder's business; and

          (2) the holder, other than broker-dealers, has no arrangement or
     understanding with any person to participate in the distribution of the
     bonds issued in the exchange offer.

     However, the SEC has not considered the exchange offer in the context of a
no-action letter and we cannot guarantee that the staff of the SEC would make a
similar determination with respect to the exchange offer as in such other
circumstances.

     Each holder, other than a broker-dealer, must furnish a written
representation, at our request, that:

          (1) it is not an affiliate of ours;

          (2) it is not engaged in, and does not intend to engage in, a
     distribution of the bonds issued in the exchange offer and has no
     arrangement or understanding to participate in a distribution of bonds
     issued in the exchange offer;

          (3) it is acquiring the bonds issued in the exchange offer in the
     ordinary course of its business; and

          (4) it is not acting on behalf of a person who could not make
     representations (1)-(3).


     Each broker-dealer that receives bonds issued in the exchange offer for its
own account in exchange for outstanding bonds:



     - must acknowledge that such outstanding bonds were acquired by such
       broker-dealer as a result of market-making or other trading activities,
       and



     - acknowledged that it must comply with the registration and prospectus
       delivery requirements of the Securities Act in connection with any resale
       transaction, including the delivery of a prospectus that contains
       information with respect to any selling holder required by the Securities
       Act in connection with any resale of the bonds issued in the exchange
       offer.


                                       31
<PAGE>   38


     Furthermore, any broker-dealer that acquired any of its outstanding bonds
     directly from our company:



        - may not rely on the applicable interpretation of the staff of the
          SEC's position contained in Exxon Capital Holdings Corp., SEC
          No-Action Letter (April 13, 1989), Morgan, Stanley & Co., Inc., SEC
          No-Action Letter (June 5, 1991) and Shearman & Sterling, SEC No-Action
          Letter (July 2, 1983) and



        - must also be named as a selling holder of bonds in connection with the
          registration and prospectus delivery requirements of the Securities
          Act relating to any resale transaction.


See "Plan of Distribution" for a discussion of the exchange and resale
obligations of broker-dealers in connection with the exchange offer.

     In addition, to comply with state securities laws of certain jurisdictions,
the bonds issued in the exchange offer may not be offered or sold in any state
unless they have been registered or qualified for sale in such state or an
exemption from registration or qualification is available and complied with by
the holders selling the bonds. We have agreed in the registration rights
agreement that, prior to any public offering of transfer restricted securities,
we will register or qualify the transfer restricted securities for offer or sale
under the securities laws of any jurisdiction requested by a holder. Unless a
holder requests, we currently do not intend to register or qualify the sale of
the bonds issued in the exchange offer in any state where an exemption from
registration or qualification is required and not available. "Transfer
restricted securities" means each bond until:

          (1) the date on which such bond has been exchanged by a person other
     than a broker-dealer for a bond in the exchange offer;

          (2) following the exchange by a broker-dealer in the exchange offer of
     a bond for a bond issued in the exchange offer, the date on which the bond
     issued in the exchange offer is sold to a purchaser who receives from such
     broker-dealer on or prior to the date of such sale a copy of this
     prospectus;

          (3) the date on which such bond has been effectively registered under
     the Securities Act and disposed of in accordance with a shelf registration
     statement that we file in accordance with the registration rights
     agreement; or

          (4) the date on which such bond is distributed to the public in a
     transaction under Rule 144 of the Securities Act.

<PAGE>   39

                                USE OF PROCEEDS

     We will not receive any proceeds from the exchange offer.

     We entered into a loan agreement, dated as of June 4, 1999, which we will
refer to as the "loan agreement", with several commercial banks and other
financial institutions, which provided for a 364-day term loan facility in an
amount up to $646.6 million, which we will refer to as the "term loan facility,"
and a 364-day revolving credit facility in an amount up to $40 million to
finance certain of our working capital needs, which we will refer to as the "old
working capital facility." We used the term loan facility to partially fund the
acquisition of our facilities (other than the Connecticut facilities). The
remainder of the purchase price for our facilities (other than the Connecticut
facilities) was funded with equity contributions from NRG Energy in the amount
of $353.6 million.

     The purchase price for the Connecticut facilities, which were acquired in
December 1999, was funded in part by equity contributions and in part by loans,
both made by NRG Energy.

     We used the proceeds from the sale of the outstanding bonds:

     - to repay all amounts of principal and interest outstanding under the term
       loan facility,

     - to pay our costs and expenses in connection with the offering of the
       bonds, and

     - to repay to NRG Energy money loaned in connection with the purchase of
       the Connecticut facilities.

     Contemporaneously with the closing of the issuance of the outstanding
bonds, we entered into a new $50 million revolving credit facility. At that
time, the loan agreement was terminated.

(a) On February 22, 2000, NRG Northeast issued $750 million of senior secured
    bonds. Approximately $646.6 million was used to repay short-term borrowings
    at December 31, 1999.



(b) Member's equity at June 30, 2000, reflects a net distribution of
    approximately $117.7 million. This net distribution consists primarily of
    the $95.8 million repayment of capital to NRG Energy and the payment of
    $21.4 million of proceeds received upon the termination of certain treasury
    locks to NRG Energy. The net distribution also includes the effect of
    removing the minority interest in NRG Northeast and other minor items. In
    addition to the net distribution described above, member's equity also
    included net income of $111.3 million.

                       SELECTED HISTORICAL FINANCIAL DATA


     The following table sets forth selected historical financial data for NRG
Northeast and the guarantors. NRG Northeast had no assets or operations prior to
its acquisition of its facilities. The Somerset facility was acquired by the
Somerset guarantor in April 1999 and ownership of the Somerset guarantor was
transferred to NRG Northeast in July 1999. The Arthur Kill, Astoria, Dunkirk and
Huntley facilities were each acquired in June 1999 and the Oswego facility was
acquired in October 1999. The Connecticut guarantors acquired their facilities
in December 1999. The ownership of the Connecticut guarantors was transferred to
NRG Northeast on the date of the issuance of the outstanding bonds. The selected
historical financial data as of and for the period ended December 31, 1999 has
been derived from the audited historical financial statements of NRG Northeast
included elsewhere in this prospectus. The selected historical financial data as
of and for the six months ended June 30, 2000 and for the period April 27, 1999
(Inception) to June 30, 1999 has been derived from the unaudited interim
historical financial statements of NRG Northeast included elsewhere in this
prospectus. The information set forth below should be read in conjunction with
the section of this prospectus captioned "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and our historical financial

---------------
(1) EBITDA is the sum of income (loss) before income taxes, interest expense
    (net of capitalized interest) and depreciation and amortization expense.
    EBITDA is a measure of financial performance not defined under generally
    accepted accounting principles, which you should not consider in isolation
    or as a substitute for net income, cash flows from operations or other
    income or cash flow data prepared in accordance with generally accepted
    accounting principles or as a measure of a company's profitability or
    liquidity. In addition, EBITDA may not be comparable to similarly titled
    measures presented by other companies and could be misleading because all
    companies and analysts do not calculate it in the same fashion.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

     The following discussion contains forward-looking statements. These
statements are based on our current plans and expectations and involve risks and
uncertainties that could cause actual future activities and results of
operations to be materially different from those set forth in the
forward-looking statements. Important factors that could cause actual results to
differ include risks set forth in "Risk Factors."

     NRG Northeast is a Delaware limited liability company formed on March 11,
1999 which, through its family of subsidiaries, owns electric generation plants
in the northeastern region of the United States. NRG Northeast is an indirect,
wholly-owned subsidiary of NRG Energy which was formed for the purpose of
financing, acquiring, owning, operating and maintaining, through its
subsidiaries and affiliates, the facilities described in this prospectus.

     The Somerset facility was acquired in April 1999 and each of the Arthur
Kill, Astoria, Dunkirk and Huntley facilities were acquired in June 1999. The
Oswego facility was acquired in October 1999. The Connecticut guarantors, which
acquired the Connecticut facilities in December, 1999, were transferred to NRG
Northeast on the date of the issuance of the outstanding bonds. These facilities
were acquired for an aggregate purchase price of approximately $1,519 million.
These purchase prices were funded by the term loan facility and certain equity
contributions and loans from NRG Energy. See "Business of NRG Northeast and the
Guarantors -- Our Generating Facilities."

     Prior to our acquisition of the facilities from ConEd, CL&P, NiMo, RG&E and
MEC, the facilities were operated by their former owners on a fully-integrated
basis with other assets and operations of those former owners. Therefore, no
historical financial information is available that would be meaningful or
indicative of the future results that may be achieved through the operation of
the facilities in light of the manner and regulatory and market environments in
which they are being operated by NRG Northeast. As a result, this Management's
Discussion and Analysis of Financial Condition and Results of Operations
reflects NRG Northeast's operations since formation but does not include a
discussion of, or comparison to, prior periods.

     Our facilities sell their electrical power to diversified customers and
markets. In the first four calendar years of the term of the bonds, we expect to
sell a significant portion of our power pursuant to transition power sales
contracts with certain of the parties from whom we purchased the facilities. We
expect to sell the remainder of our power during this period primarily by
bidding into the New England Power Pool, and the New York Power Pool which is
located in New York City and certain surrounding areas, the power pools in which
our facilities are located, and power pools in other areas.

                                       36
<PAGE>   43

  GENERAL AND ADMINISTRATIVE EXPENSES

     General and administrative expenses were $7.8 million and included costs
for outside legal and other contract services, payments to NRG Energy for
corporate services, expenses related to office administration, as well as costs
for certain employee benefits incurred under operating service agreements.

  INTEREST EXPENSE


     Interest expense was $26.4 million, which included $22.7 million of
interest on loans and $3.7 million of amortization of deferred financing costs.
The interest on loans relates to the loan agreement, which includes the term
loan facility and the old working capital facility. The weighted average
interest rate on these facilities for the period was 6.86% and principal amounts
owed under the facilities as of December 31, 1999, were $682.3 million.


LIQUIDITY AND CAPITAL RESOURCES


     In order to maintain the long-term high availability of our facilities, we
will incorporate standard overhaul cycles for major equipment. Funding is
budgeted to maintain existing equipment, to determine areas of replacement or
repair in order to sustain availability and to identify major expenses in
advance. We believe that our budgeted amounts will be sufficient to implement
the independent engineer's recommendations we received in connection with the
issuance of the outstanding bonds for this period of time and the independent
engineer has confirmed our budget as sufficient for this period. We have
budgeted in excess of $40 million for capital expenditures between 2000 and 2004
for environmental compliance, which includes the possible installation of NO(x)
control technology at the Somerset facility, intake screens at the Dunkirk
facility, the resolution of consent orders for remediation at the Arthur Kill
and Astoria facilities and the resolution of a consent order for water intake at
the Arthur Kill facility. The budget does not include capital expenditures that
may be required with respect to air pollution control initiatives recently
undertaken by New York City, New York State, Connecticut and Massachusetts or
with more expensive cooling water intake technology that may be required at our
Arthur Kill facility. See "Business of NRG Northeast and the
Guarantees -- Environmental Matters."


     The use of the proceeds from the sale of the outstanding bonds was applied
as follows: (i) to repay all amounts of principal and interest outstanding under
the term loan facility, (ii) to pay our costs and expenses in connection with
the offering of the outstanding bonds, and (iii) to repay to NRG Energy money
loaned in connection with the purchase of the Connecticut facilities in December
1999. In addition, on the date of the issuance of the outstanding bonds, we
replaced our old working capital facility with a new $50 million working capital
facility. The indenture also permits certain additional borrowings as described
under "Description of Principal Financing Documents -- Indenture." We expect
that funds from our operations, borrowings under our new working capital
facility and other borrowings will be sufficient for our cash needs.

     Pursuant to the indenture, we are required to establish a debt service
reserve account for the benefit of the holders of the bonds. This account must
contain at all times a sufficient amount to pay the projected principal and
interest payments on the bonds for the next six months. We have the option of
funding the debt service reserve account through cash or providing a debt
service reserve support instrument. NRG Energy has initially provided a debt
service reserve support instrument in the form of a guarantee to satisfy our
debt service reserve requirements with respect to the bonds.

SEASONALITY OF POWER GENERATION BUSINESS

     Power sales are highly seasonal and are affected by unusual weather
conditions. While long-term prices of electricity are affected by the market
factors discussed above, such as current and future supply of electricity
generation capacity, the price of fuel to existing and potential new entrant
power stations and the transmission capacity between different regions,
short-term prices in the NYPP and the NEPOOL may also be affected by weather
conditions. Peak demand for electricity occurs during the summer months, caused
by increased use of air-conditioning equipment. Cooler than normal summer
temperatures may lead to reduced use of air-conditioners. This reduces
short-term electricity demand, and, consequently, may lead to a reduction in
wholesale electricity prices. To the extent that the output of the facilities
during these periods is not under contract, their revenue would be adversely
affected.

RECENT DEVELOPMENTS

     On January 19, 2000, NRG Energy announced the execution of an agreement to
acquire 1,875 MW of fossil-fueled electric generating capacity and other assets
from Conectiv, an electric utility based in Wilmington, Delaware. While we had
stated that it was possible that NRG Energy may elect to contribute or transfer
the Conectiv facilities to us, since the issue of the outstanding bonds NRG
Energy has decided it will not make such contribution or transfer.


     On May 31, 2000, FERC approved a request of the NY ISO, to impose price
limitations on one ancillary service, Ten Minute Non-synchronized Reserves, on a
prospective basis only, effective March 28, 2000, the date the NY ISO began
capping bids for that service. FERC rejected the NY ISO's request for authority
to adjust the market-clearing prices for that service on a retroactive basis. As
a result of the FERC order (unless the NY ISO or another party successfully
appeals the order), we will retain the approximately $8.0 million of revenues
collected in February 2000 and approximately $8.2 million included in revenues,
but not yet collected, for March 2000. The NY ISO has sought reconsideration of
the FERC order on June 30, 2000.



     On June 5, 2000, NRG Energy consummated the initial public offering of its
common stock. Upon completion of the offering, Northern States Power Company
owned approximately 82% of the stock outstanding and 98% of the combined voting
power of NRG Energy's common stock and class A common stock. As a result of the
merger of New Century Energies, Inc. into Northern States Power in August 2000,
the corporation surviving the merger, Xcel Energy Inc., indirectly owns the
shares of NRG Energy's common stock and class A common stock previously held by
Northern States Power.


USE OF DERIVATIVES AND MARKET RISK

     We may from time to time use derivative financial instruments to manage
exposure to fluctuations in interest rates. The use of these instruments may
expose us to market and credit risks. We have executed ISDA Master Agreements
with Citibank, N.A. and with The Chase Manhattan Bank pursuant to which we may
from time to time enter into interest rate swap and cap agreements and other
hedging transactions to moderate exposure to interest-rate changes and to lower
our overall cost of borrowing, and for other purposes. As of December 31, 1999,
we had in place six interest rate hedges with three separate counterparties, in
order to hedge our exposure to interest-rate changes in respect of the offering
of the outstanding bonds. These "treasury locks" had a notional amount of $600
million and had a market value of approximately $19.2 million at December 31,
1999. These hedges expired on February 29, 2000. We paid NRG Energy the proceeds
received by us from these contracts, which totaled $21.4 million.

     Management believes that over exposure to credit risk due to
non-performance by the counterparties to its hedging contracts is insignificant
based on the investment grade rating of the counterparties.

NEW ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standard Board (FASB) issued
Statement of Financial Accounting Standard (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities." This statement requires that all
derivatives be recognized at fair value in the balance sheet, and that changes
in fair value be recognized either currently in earnings or deferred as a
component of other comprehensive income, depending on the intended use of the
derivative, its resulting designation and its effectiveness. We plan to adopt
this standard in 2001, as required. The potential impact of implementing this
statement has not yet been determined.

     In June 2000, the FASB issued SFAS No. 138, "Accounting for Certain
Derivative Instruments and Certain Hedging Activities, an Amendment of FASB
Statement No. 133." This statement amends SFAS 133 in four areas, normal
purchases and sales contracts, definition of interest rate risk, hedging
recognized foreign currency denominated assets and liabilities and hedging
foreign currency risk and intercompany derivatives. We plan to adopt the
standard, as required. The potential impact of implementing this standard has
not been determined.

     NRG Energy owns all or a portion of 63 generation projects that have total
generating capacity of 24,533 MW. Its net ownership interest in those projects
is 14,476 MW. Upon the closing of NRG Energy's pending acquisition from Conectiv
of interests in six power generation facilities, which NRG Energy expects to
occur in early 2001, it will have interests in projects having a total
generating capacity of 29,595 MW and its net ownership interest in those
projects will be 16,351 MW. NRG Energy has experienced significant growth in the
last year, expanding from 3,300 MW of net ownership interests in power
generation facilities (including those under construction) as of December 31,
1998 to 10,990 MW of net ownership interests as of December 31, 1999 and to
14,476 MW as of September 30, 2000.


     NRG Energy has historically endeavored to make capital for additional
investments available by allowing other companies to purchase a portion of NRG
Energy's interests in companies wholly-owned by NRG Energy. While such a
sell-down of NRG Energy's interest in NRG Northeast is not currently
contemplated by NRG Energy, any potential holders of the bonds should consider
that such a sell-down is a possibility.

                  BUSINESS OF NRG NORTHEAST AND THE GUARANTORS

INDUSTRY OVERVIEW

     Until recently, the demand for power in the United States has been met by
utilities which would construct large-scale electric generating plants under
cost-of-service based regulation. Under this regulatory regime, in exchange for
their status as the designated provider of electricity in a given area, the
traditional electric utility agreed to submit its decisions regarding operation
of its business (e.g., construction of plants, closure of plants, etc.) to
public service commission scrutiny, and in exchange it received a moderate
guaranteed rate of return on the costs incurred in providing electric service.

     Beginning in 1978, legislative changes designed to increase competition in
the electric industry spurred independent power producers to enter the power
market, beginning with an entrepreneurial group of cogenerators and small power
producers which was later joined by larger, better capitalized companies, such
as subsidiaries of fuel supply companies, electric utilities, engineering
companies, equipment manufacturers and affiliates of other industrial companies.
While these independent power producers were not subject to public service
commission review and scrutiny with respect to decisions they made and costs
they incurred, they were also not guaranteed any specified rate of return with
respect to their investments.

     Many of the newly constructed or acquired independent power assets operate
without long-term power purchase agreements in place, selling their output into
the market or through shorter term bilateral contracts. Our facilities have
committed a portion of our energy and capacity pursuant to the transition power
sales contracts and we plan to sell our uncommitted energy, capacity and
ancillary services either directly into the market, through future power sales
contracts or pursuant to arrangements with power marketing entities. While the
absence of a long-term power purchase agreement introduces certain relatively
new risks and uncertainties to independent power producers, and requires careful
advance analysis of the local power markets, we believe this arrangement is
becoming increasingly accepted in the domestic independent power market.

     The United States electric industry, including companies engaged in
providing generation, transmission, distribution and ancillary services, has
undergone significant change over the last several years, leading to significant
deregulation and increased competition. The FERC, pursuant to Order No. 888 and
Order No. 889, and as further refined and supplemented by Orders 888-A, -B and
-C (collectively, the "Open Access Rules"), requires the owners and operators of
electric transmission facilities to make those facilities available for
transmission on a non-discriminatory basis to all wholesale generators, sellers
and buyers of electricity ("wholesale wheeling").

     The FERC has proposed further regulatory changes to improve access to the
nationwide transmission grid by utility and non-utility purchasers and sellers
of electricity and to promote wholesale market efficiency. In December 1999, the
FERC issued order No. 2000, which set forth minimum requirements for the
establishment and operation of Regional Transmission Organizations ("RTOs").
Order No. 2000 also set forth a voluntary procedure by which RTOs would be
established. In addition to wholesale wheeling, throughout the United States
there has been an increasing number of proposals at the state level to allow
retail customers to choose their electricity suppliers, with incumbent utilities
required to deliver such electricity over their transmission and distribution
systems ("retail wheeling"). Numerous electric utilities nationwide are in the
process of divesting all or a portion of their generation business or are
expected to commence such a process in the foreseeable future, as legislative
and regulatory developments drive the industry to disaggregate.

REGULATION

  FEDERAL LAW

     Federal Power Act.  The Federal Power Act gives the FERC exclusive
rate-making jurisdiction over wholesale sales of electricity and the
transmission of electricity in interstate commerce. Pursuant to the Federal
Power Act, all public utilities subject to the FERC's jurisdiction are required
to file rate schedules with the FERC prior to commencement of wholesale sales or
transmission of electricity. Because the

                                       41
<PAGE>   48

guarantors will be selling power in the wholesale market, they are deemed to be
public utilities for purposes of the Federal Power Act. Arthur Kill Power,
Astoria Power, Dunkirk Power, Huntley Power, and Somerset Power applied for and
were granted market-based rate authority for the wholesale sales of power by the
FERC in Spring and early Summer 1999. Oswego Power filed for market-based rates
on July 19, 1999 and was granted market-based rate authority on September 15,
1999. On September 1, 1999, Connecticut Jet Power, Devon Power, Middletown
Power, Montville Power and Norwalk Power filed for market-based rates. The FERC
granted market-based rate authority to these guarantors on November 10, 1999. In
its orders, the FERC also granted waivers of certain of the accounting,
record-keeping and reporting requirements that are imposed on public utilities
with cost-based rate schedules.

     In addition, the FERC's orders, as is customary with market-based rate
schedules, reserved the right to suspend, upon complaint, market-based rate
authority on a prospective basis if it is subsequently determined that we or any
of our affiliates exercised market power. If the FERC were to suspend
market-based rate authority, it would most likely be necessary to file, and
obtain FERC acceptance of, cost-based rate schedules. In addition, the loss of
market-based rate authority would subject the guarantors to the accounting,
record-keeping and reporting requirements that are imposed on public utilities
with cost-based rate schedules.

     Public Utility Holding Company Act.  PUHCA provides that any corporation,
partnership or other entity or organized group that owns, controls or holds
power to vote 10% or more of the outstanding voting securities of a "public
utility company" or a company that is a "holding company" of a public utility
company is subject to registration and regulation under PUHCA as a registered
holding company, unless an exemption is established or an order is issued by the
SEC declaring it not to be a holding company. Registered holding companies under
PUHCA are required to limit their utility operation to a single integrated
utility system and to divest any other operations not functionally related to
the operation of the utility system. In addition, a public utility company that
is a subsidiary of a registered holding company under PUHCA is subject to
financial and organizational regulation, including approval by the SEC of
certain of its financing transactions. However, under the Energy Policy Act, a
company engaged exclusively in the business of owning and/or operating a
facility used for the generation of electric energy exclusively for sale at
wholesale may be exempted from PUHCA regulation by operation of its status as an
exempt wholesale generator ("EWG") as defined under Section 32 of PUHCA. Each of
the guarantors qualifies to be an EWG and has filed with the FERC to confirm
that status.

     If there occurs a "material change" in facts which might affect any of the
guarantors' continued eligibility for EWG status, within 60 days of such
material change, the relevant guarantor must (i) file a written explanation of
why the material change does not affect its EWG status, (ii) file a new
application for EWG status or (iii) notify the FERC that it no longer wishes to
maintain EWG status. If any of the guarantors were to lose its EWG status, we,
along with our affiliates, would be subject to regulation under PUHCA as a
public utility company. Absent a substantial restructuring of our business, it
would be difficult for us to comply with PUHCA without a material adverse effect
on our business.

  STATE LAW

     New York.  Pursuant to the New York Public Service Law (the "NYPSL"), the
New York Public Service Commission ("NYPSC") regulates all "public utility
companies" or "utility companies" operating in New York. A "public utility
company" or "utility company" under the NYPSL includes, among other things, any
entity engaged in the production, transmission or distribution of electricity to
the public for light, heat or power purposes. The Huntley, Dunkirk, Oswego,
Arthur Kill and Astoria facilities (the "New York facilities"), each considered
an EWG, will not provide electricity directly to the public and each plans to
sell only at wholesale to power marketers, energy service companies or the NYPP.
Although the NYPSL is silent with respect to the utility status of electric
corporations selling at wholesale within New York, precedent of the NYPSC has
applied "lightened regulation" to New York EWGs, which provides for minimal
financial and organizational regulation. Each of the New York facilities has
been accorded lightened regulatory treatment by the NYPSC. The New York
facilities' rates, however, remain subject to the jurisdiction of the FERC.

                                       42
<PAGE>   49

     Massachusetts.  Pursuant to Chapter 164 of the Massachusetts General Laws,
a "wholesale generation company" includes any company engaged in the business of
producing, manufacturing or generating electricity for sale at wholesale only.
The Somerset facility, as an EWG, will not provide electricity directly to the
public and plans to sell only at wholesale to power marketers and energy service
companies and thus would be considered a wholesale generation company. Such
companies are subject to very limited regulation by the Massachusetts Department
of Telecommunications and Energy ("MDTE"), and the Somerset facility will not
likely be subject to regulation as a Massachusetts public utility or electric
company. If, however, the Somerset facility were deemed to be an electric
company by the MDTE, the MDTE could retroactively apply certain provisions of
the statutes to the Somerset facility. The Somerset facility would also be
subject to other laws and regulations (other than rate regulation) applicable to
Massachusetts electric companies. The Somerset facility's rates, however, would
remain subject to the jurisdiction of the FERC.

     Connecticut.  Pursuant to Title 16, Chapter 283 of the Connecticut General
Statutes, a "foreign electric company" is a corporation organized under the laws
of a state other than Connecticut authorized by that state to generate electric
energy. A foreign electric company is allowed to acquire and operate electric
utility facilities, which include generating stations, in Connecticut. However,
any foreign electric company which owns or operates any utility facility in the
state is deemed to be an "electric company" and a "public service company" for
all purposes of Title 16.

     Pursuant to Title 16, Chapter 277 of the Connecticut General Statutes, a
"public service company" includes electric companies, but does not include EWGs.
An "electric company" includes every corporation engaged in generating
electricity to be transmitted or distributed within the state, but does not
include an EWG. The Connecticut Department of Public Utility Control ("DPUC")
has authority to adopt rules with respect to rates and charges, services,
accounting practices, safety and the conduct of operations generally of public
service companies, as it deems reasonable and necessary. The DPUC also must
approve the merger or consolidation of any public service company, and the
issuance of common stock, notes, bonds, evidence of indebtedness, or securities
by any public service company. A waiver of the requirement for preapproval of
debt and securities issuances is available if the foreign state of incorporation
regulates such issuances.

     Since they are EWGs, Middletown Power, Montville Power, Norwalk Power,
Devon Power, and Connecticut Jet Power will not likely be regulated as public
service companies or electric companies by the DPUC. If, however, the
Connecticut facilities were deemed to be public service companies or electric
companies by the DPUC, the DPUC could retroactively apply certain provisions of
the statutes to the Connecticut facilities. The Connecticut facilities would
also be subject to other laws and regulations (other than rate regulation)
applicable to Connecticut public service or electric companies. The rates for
each of the Connecticut facilities, however, would remain subject to the
jurisdiction of the FERC.

     Certain Regulatory Approvals.  In order to put in place the ownership
structure described in this prospectus, we sought and received approval from the
FERC with respect to the transfers to NRG Northeast on the date of the issuance
of the outstanding bonds of: (i) the 0.5% membership interests in the New York
and Massachusetts guarantors previously held by each of the members of NRG
Northeast and (ii) the interest of NRG Connecticut, another subsidiary of NRG
Energy, in the Connecticut guarantors. On January 10, 2000, we filed with the
FERC requesting these approvals. We received these approvals on February 10,
2000 and they have subsequently become final. In addition, in order to enable
the New York guarantors to provide their guarantees in respect of the bonds, we
sought and received the approval of the NYPSC. We filed with the NYPSC
requesting this approval on January 11, 2000. We received this approval on
February 9, 2000, and it has subsequently become final.

COMPETITION

     FEDERAL.  The Energy Policy Act laid the ground work for a competitive
wholesale market for electricity. Among other things, the Energy Policy Act
expanded the FERC's authority to order wholesale wheeling, thus allowing
qualifying facilities under Public Utility Regulatory Policies Act, power
marketers and EWGs to compete more effectively in the wholesale market.

                                       43
<PAGE>   50

     In May 1996, the FERC issued the first of the Open Access Rules, which
requires utilities to offer eligible wholesale transmission customers
non-discriminatory open access on utility transmission lines on a comparable
basis to the utilities' own use of the lines. In addition, the Open Access Rules
direct the regional power pools (including the NYPP and the NEPOOL) that control
the major electric transmission networks to file uniform, non-discriminatory
open access tariffs. The Open Access Rules have been the subject of rehearing at
the FERC and are now undergoing judicial review.

     Over the past few years, Congress and the administration of President
Clinton have considered various pieces of legislation to restructure the
electric industry that would require, among other things, customer choice and/or
repeal of PUHCA. The debate is likely to continue, and perhaps intensify. The
effect of enacting such legislation cannot be predicted with any degree of
certainty.

     STATE.  The Energy Policy Act did not preempt state authority to regulate
retail electric service. Historically, in most states, competition for retail
customers is limited by statutes or regulations granting existing electric
utilities exclusive retail franchises and service territories. Since the passage
of the Energy Policy Act, the advisability of retail competition has been the
subject of intense debate in federal and state legislative and regulatory
forums. Many states have taken steps to facilitate retail competition as a means
of stimulating competitive generation rates. Retail competition commenced in New
York and Massachusetts in 1998. Full retail competition commenced in Connecticut
on July 1, 2000.

POWER MARKETS

     THE NEW YORK POWER POOL.  The NYPP includes 34,000 MW of installed capacity
and serves almost all of New York State's electric power requirements. The
current members of the NYPP include the six New York investor-owned utilities,
the Long Island Power Authority and the New York Power Authority, various local
and municipal utilities, as well as a growing number of independent power
producers and power marketers. The NYPP has been restructured as a competitive,
non-discriminatory market through, among other things, the establishment of the
NY ISO and the creation of bid-based markets for energy, capacity and ancillary
services. The NY ISO commenced operations in November 1999. Most of New York
State's investor-owned utilities have completed or are in the process of
divesting their fossil generation assets as part of the restructuring of the
state's electricity markets. These divested plants will compete to varying
degrees with new merchant plants in the wholesale markets. The market-clearing
price for the NYPP's day-ahead and real-time energy markets will be calculated
by the NY ISO by determining the market-clearing price for transactions with
zonal adjustments to account for transmission constraints. All purchasers of
energy from the market will also pay a transaction charge set by the NY ISO to
settle system energy balancing and certain ancillary service costs.

     THE NEW YORK CITY IN-CITY MARKET.  In connection with the divestiture by
ConEd of certain of its electric generating resources in the New York City
in-city market, certain market power mitigation measures will be applied to
generators located in that area. The intent of these market power mitigation
measures is to alleviate concerns that the divested generation resources might
be able to exercise localized market power due to the current configuration of
New York City in-city market loads, generation, and transmission facilities and
related local reliability rules and transmission constraints. The market
mitigation measures are intended to be implemented by the NY ISO and tracked
through its market monitoring process.


     On May 31, 2000, FERC approved a request of the NY ISO to impose price
limitations on one ancillary service, Ten Minute Non-synchronized Reserves, on a
prospective basis only, effective March 28, 2000, the date the NY ISO began
capping bids for that service. FERC rejected the NY ISO's request for authority
to adjust the market-clearing prices for that service on a retroactive basis. As
a result of the FERC order (unless the NY ISO or another party successfully
appeals the order), we will retain the approximately $8.0 million of revenues
collected in February 2000 and approximately $8.2 million included in revenues,
but not yet collected, for March 2000. The NY ISO has sought reconsideration of
the FERC order.


     THE NEW ENGLAND POWER POOL.  The NEPOOL was originally formed to capture
the benefits of economic dispatch and joint planning between a large number of
utilities. The NEPOOL is populated with a large number of small utilities. The
region is a high variable cost power market, with oil/gas units operating in the
                                       44
<PAGE>   51

margin. The NEPOOL has a large number of nuclear units, the continuing
operational status of which is, at present, unclear; this factor adds pressure
to the capacity needs in the NEPOOL service area. In addition, the region has
transmission constraints that limit imports from neighboring regions. As such,
the NEPOOL will require significant new capacity additions over the next few
years: approximately 7,000 MW of new capacity is projected to be needed by 2005,
driven by (i) current deficiencies and increased shortfalls due to load growth;
and (ii) economic retirements of older and inefficient units. The deficit could
grow much larger if there are further shutdowns of nuclear plants or aging
fossil capacity.

     There are over 30,000 MW of new merchant plant proposals in the NEPOOL.
However, only about 2,500 MW of new merchant plants is actually under
construction. Virtually all proposals for new merchant plants in the NEPOOL are
for gas-fired combined cycle facilities, and are designed to meet incremental
generation requirements, and displace older, less efficient units. Some of this
capacity will require the addition of new gas pipeline capacity into New
England. In addition, approximately 12,500 MW of capacity in the NEPOOL has been
divested or is in the process of being divested. These divested generation
assets will compete with the new merchant plants in the wholesale market.

     On May 1, 1999, ISO New England began administering the NEPOOL's
electricity marketplace through which energy, automatic generation control, and
several capacity services are supplied. ISO New England is a "day-ahead-hourly"
marketplace. This means that wholesale electricity suppliers and generators bid
their resources into the market the day before and submit separate bids for each
resource for each hour of the day. ISO New England tabulates the bids and stacks
them in dollar terms from lowest to highest matching the expected hourly demand
forecast for that hour and each hour in the next day. The ISO New England
operations staff then determines the least cost dispatch sequence for the next
day which reflects the actual bids. Generators will then be dispatched to match
the actual load occurring on the system. Unlike in the NYPP, there is no
hour-ahead market in the NEPOOL. Actual energy balancing differences from the
day-ahead schedule are accounted for through an uplift charge.

OUR GENERATING FACILITIES

     We own a total of ten fossil fuel-fired and six remote gas turbine electric
power generation facilities, as described below. The purchase price set forth
below for certain of the facilities is based on an allocation made by us where
more than one facility was purchased pursuant to the same purchase and sale
agreement.

     ARTHUR KILL FACILITY.  The Arthur Kill facility was acquired from ConEd in
June 1999 for a purchase price of $395.5 million. The Arthur Kill facility,
located in Staten Island, New York, is a natural gas/oil-fired
intermediate/peaking plant consisting of 3 units and having capable capacity of
842 MW (including a black start gas turbine). We expect the Arthur Kill facility
to benefit from its location in the New York City in-city market due to
requirements that load-serving entities must contract with resources located in
the New York City in-city market for 80% of their needs, and there is limited
ability to build new capacity in this area or to gain access to this area by
means of transmission.

     ASTORIA FACILITY.  The Astoria facility was acquired from ConEd in June
1999 for a purchase price of $109.5 million. The Astoria facility, located in
Queens, New York, is a gas/liquid fuel-fired peaking plant consisting of 11
units and having capable capacity of 614 MW. We expect the Astoria facility to
benefit from its location in the New York City in-city market due to
requirements that load-serving entities must contract with resources located in
the New York City in-city market for 80% of their needs, and there is limited
ability to build new capacity in this area or to gain access to this area by
means of transmission.

     CONNECTICUT JET FACILITIES.  Six unmanned ICU facilities were acquired from
CL&P in December 1999 for a purchase price of $22.3 million. These ICU
facilities, located at local switchyards in Branford, Torrington Terminal,
Franklin Drive and Cos Cob, are oil-fired peaking units consisting of 6 units
and having an aggregate capable capacity of 110 MW.

     DEVON FACILITY.  The Devon facility was acquired from CL&P in December 1999
for a purchase price of $113.3 million. The Devon facility, located in Milford,
Connecticut, is a natural gas/oil-fired intermediate/peaking load facility
consisting of 7 units and having capable capacity of 358 MW.

                                       45
<PAGE>   52

     DUNKIRK FACILITY.  The Dunkirk facility was acquired from NiMo in June 1999
for a purchase price of $193.3 million. The Dunkirk facility, located in
Dunkirk, New York (near Buffalo), is a coal-fired base-load facility consisting
of 4 units and having capable capacity of 582 MW. The Dunkirk facility is among
the lowest variable cost fossil fuel plants that sell into the NYPP. We plan to
operate it as a base-load facility.

     HUNTLEY FACILITY.  The Huntley facility was acquired from NiMo in June 1999
for a purchase price of $161.7 million. The Huntley facility, located five miles
northeast of Buffalo, New York, is a coal-fired base-load facility consisting of
6 units and having capable capacity of 566 MW. The Huntley facility is among the
lowest cost fossil fuel plants that sell into the NYPP. We plan to operate it as
a base-load facility.

     MIDDLETOWN FACILITY.  The Middletown facility was acquired from CL&P in
December 1999 for a purchase price of $225.8 million. The Middletown facility,
located in Middletown, Connecticut, is a natural gas/oil-fired
intermediate/peaking plant consisting of 4 units and having capable capacity of
770 MW.

     MONTVILLE FACILITY.  The Montville facility was acquired from CL&P in
December 1999 for a purchase price of $82.8 million. The Montville facility,
located in Uncasville, Connecticut, is a natural gas/oil-fired
intermediate/peaking load plant consisting of 4 units and having a capable
capacity of 498 MW.

     NORWALK FACILITY.  The Norwalk facility was acquired from CL&P in December
1999 for a purchase price of $75.0 million. The Norwalk facility, located in
Norwalk, Connecticut, is an oil-fired intermediate/peaking load plant consisting
of 3 units and having capable capacity of 342 MW.

     OSWEGO FACILITY.  The Oswego facility was acquired from NiMo and RG&E in
October 1999 for a purchase price of $84.9 million. The Oswego facility, located
in Oswego, New York, is a natural gas/oil-fired peaking plant consisting of 2
units and having capable capacity of 1,660 MW. The Oswego facility has very low
cost capacity and is a source of excess emissions allowances that can be
utilized at our other facilities. We expect to operate this facility as a
peaking facility.

     SOMERSET FACILITY.  The Somerset facility was acquired from MEC in April
1999 for a purchase price of $55.2 million. The Somerset facility, located in
Somerset, Massachusetts, is an oil/coal-fired base-load/peaking facility
consisting of 3 units and having capable capacity of 153 MW. One unit
representing approximately 24 MW of capacity is currently leased to VELCO. The
Somerset facility provides low variable cost capacity, strategically positioned
to sell power into the NEPOOL. We intend to operate this facility as a peaking
and base-load facility, depending on market conditions.

     We believe the Connecticut facilities are strategically positioned for
sales into the NEPOOL and have a competitive advantage on transmission charges;
we will operate these facilities as peaking and intermediate facilities to take
advantage of market volatility. In addition, we believe certain of the
facilities and facility sites represent opportunities for repowering and/or
expansion of generation capacity. We believe it may be possible at the Huntley
and Arthur Kill facilities to generate revenues through steam sales. In
addition, we believe there are opportunities to improve on the existing fuel
supply arrangements at the facilities.

NRG NORTHEAST OPERATIONS

     We are a major owner of independent electric power generation in the
northeastern region of the United States. Our regional base of competitive
generating facilities is close to major load centers. We intend to pursue a
strategy of enhancing profitability and competitiveness of these facilities
through their efficient operation. We believe the diversity of our facilities,
in terms of operational characteristics, location in and access to multiple
power pools and fuel sources, is an important part of this strategy.

     In order to operate our facilities and be competitive in the northeast
market, we need to address power marketing, fuel procurement, emissions
management and operations and maintenance issues relating to the facilities. We
are utilizing certain resources of NRG Energy and its affiliates by entering
into contracts with NRG Energy, NRG Power Marketing and subsidiaries of NRG
Operating Services, to provide key financial, operational and administrative
services to us.

     In particular, NRG Power Marketing, a wholly-owned subsidiary of NRG
Energy, has entered into power sales and agency agreements with each of the
guarantors for terms of approximately 30 years. NRG Power
                                       46
<PAGE>   53

Marketing provides all power marketing services, fuel procurement services, and
emissions management services for the guarantors.

     POWER MARKETING.  NRG Power Marketing provides power marketing services to
the guarantors, including scheduling, pool bidding, contract management and
bilateral sales of excess capacity, energy and ancillary services, with gross
receipts less costs incurred due to the guarantors from such activities flowing
to NRG Northeast. NRG Power Marketing has the exclusive rights to market all
capacity, energy and ancillary services produced by the guarantors that the
guarantors have not otherwise committed under other contracts.

     NRG Power Marketing will have an agency role in scheduling to the
appropriate independent system operator or power pool, and will also have a
principal role for bilateral sales and wheeling of energy to other power pools.
NRG Northeast and the guarantors will continue to evaluate the tradeoffs between
long-term contractual opportunities and shorter term merchant sales. See
"Summary of Certain Principal Project Documents."

     NRG Power Marketing is directed to use NRG Northeast assets to maximize net
operating margins. With baseload units and facilities, NRG Power Marketing will
seek a constant reduction of fixed and variable costs in combination with
improved capacity factors. With intermediate/peaking units and facilities, NRG
Power Marketing will maximize revenues during peak pricing periods and minimize
expenses during low pricing periods.

     The New York facilities sell capacity, energy and voltage support into the
NYPP centralized power market. The Somerset facility and the Connecticut
facilities sell capacity, energy and voltage support into the NEPOOL's
centralized power market. Our facilities may also enter into bilateral contracts
for the sale of capacity and energy to power marketers and load serving entities
within the NYPP, the NEPOOL and surrounding markets, as applicable. Our
facilities currently sell capacity, energy and ancillary services pursuant to
certain transition power sales contracts which range in term from one to ten
years.

     FUEL PROCUREMENT.  NRG Power Marketing provides fuel procurement services
to the guarantors for natural gas, coal and oil procurement; local gas
distribution and transportation company balancing; pipeline capacity purchasing
and balancing; position reporting; fuel inventory management; and barge and rail
management. As part of NRG Northeast's fuel procurement strategy, NRG Power
Marketing will pursue short and intermediate fuel contracts to hedge power sales
contracts and other forward sales of power. It will also actively manage the
fuel inventory and attempt to reduce barge, rail, inventory, fuel handling and
gas distribution charges.

     EMISSIONS MANAGEMENT.  NRG Power Marketing provides emissions management
services for tracking, procurement, sales and allocation of emissions
allowances. Emissions management will be closely integrated with plant
generation planning. NRG Power Marketing will also assist in performing ongoing
analyses comparing costs of installing and operating environmental control
equipment to emissions allowance procurement.

     RISK MANAGEMENT.  NRG Power Marketing will utilize certain risk management
policies and procedures to assist us with our objective of maximizing net
operating margins while minimizing the risks associated with the cash flows
derived from these assets. Key risk management guidelines adopted by NRG Power
Marketing include: (i) a general prohibition on speculative activities; (ii)
mitigation of operational risk by not allowing more than 50% of available output
not already contracted to be sold forward unless approved by the NRG Power
Marketing board of directors; (iii) approval of counter-parties and their
trading limits by NRG Energy's treasury; and (iv) fuel and emissions allowance
requirements to be matched with future power sale commitments. These risk
management policies and procedures can only be changed by the board of directors
of NRG Power Marketing.

     OPERATIONS AND MAINTENANCE.  Each of the guarantors has entered into an
operation and maintenance agreement with a facility-specific subsidiary (other
than the guarantors which own the Connecticut Jet and Middletown facilities,
which share an operator) of NRG Operating Services, which is a direct,
wholly-owned subsidiary of NRG Energy. The agreements are effective for five
years, with options to extend beyond five years. Under the agreements, the NRG
Operating Services company operator will be reimbursed for usual and
                                       47
<PAGE>   54

customary costs related to providing the services, including plant labor and
other operating costs. NRG Energy, through NRG Operating Services or other
subsidiaries, currently has contracts for the operations and maintenance of
approximately 7,800 MW of power generation at thirty-one facilities worldwide,
excluding the NRG Northeast assets.

     Each NRG Operating Services subsidiary will perform all administrative,
operations and maintenance work at its respective facility, including:

     - coordinating the fuel delivery, unloading and inventory;

     - developing a spare parts and inventory program;

     - meeting external performance standards for transmission of electricity;

     - providing operating and maintenance consulting to the guarantors as the
       guarantors may deem necessary and desirable;

     - performing and recording periodic operational tests of the facility
       equipment scheduled by NRG Power Marketing in accordance with the NEPOOL
       or the NYPP requirements, the manufacturer's specifications, legal
       requirements, environmental guidelines and other established guidelines;

     - cooperating with and assisting the guarantors in performing the
       guarantors' obligations under agreements related to each facility;

     - assisting its respective guarantor in preparing the budgets, including
       providing operating budgets, rolling five year forecasts and providing
       notice to the respective guarantor that the operating expenses exceed or
       are expected to exceed the approved operating budget; and

     - disposing of all waste material in accordance with legal requirements and
       the guarantor's waste disposal arrangements, if any.

     There are incentive fees and penalties based on performance in each
operation and maintenance agreement that attempt to align the operator's
incentives with NRG Northeast's incentives for additional net operating margin.
To ensure knowledge transfer, each operator has retained most of the plant
operators previously employed by the sellers of our facilities.

ENVIRONMENTAL MATTERS

     GENERAL.  NRG Northeast and its guarantors, like most industrial
enterprises, are subject to regulation with respect to the environmental impact
of their operations, including air and water quality control, limitations on
land use, disposal of wastes, aesthetics and other matters.


     Environmental laws generally require air emissions and water discharges to
meet specified limits. They also impose potential joint and several liability,
without regard to fault, on the generators of various hazardous substances to
manage these materials properly and to clean up property affected by the
production and discharge of such substances. We have budgeted in excess of $40
million for capital expenditures between 2000 and 2004 for environmental
compliance, which includes the possible installation of NO(x) control technology
at the Somerset facility, intake screens at the Dunkirk facility, the resolution
of consent orders for remediation at the Arthur Kill and Astoria facilities, the
resolution of a consent order for water intake at the Arthur Kill facility, and
completing remediation-related requirements under the Connecticut Transfer Act.
The budget does not include capital expenditures that may be required with
respect to air pollution control initiatives recently undertaken by New York
City, New York State, Connecticut and Massachusetts or with more expensive
cooling water intake technology that may be required at our Arthur Kill
facility. See "Management's Discussion and Analysis of Financial Condition and
Results of Operation -- Liquidity and Capital Resources."


     As a result of alleged historical noncompliance with environmental laws and
regulations, ConEd, the former owner of the Arthur Kill facility and the Astoria
facility, executed a series of consent orders with the

                                       48
<PAGE>   55

NYDEC commencing in 1993. The consent orders imposed a number of obligations on
ConEd, including, but not limited to,

     - the evaluation of the impact of water intake screens on aquatic species;

     - the investigation and remediation of spills and releases of petroleum and
       transformer fluids;

     - the evaluation of wastewater discharge points to determine if all such
       locations have been permitted;

     - the inspection and evaluation of above ground petroleum storage tanks,
       including the secondary containment for such tanks, and implementation of
       corrective actions, if necessary;

     - the performance of tightness testing of underground pipelines associated
       with the above ground storage tanks; and

     - compliance with air pollution requirements related to visible emissions.


     The ConEd consent orders include provisions establishing stipulated
penalties for violations of the orders. In connection with the acquisition of
the Arthur Kill facility and the Astoria facility, Arthur Kill Power and Astoria
Power assumed ConEd's remaining obligations under the consent orders to the
extent the orders apply to those facilities. Arthur Kill Power and Astoria Power
are currently negotiating a consent order with the NYDEC to memorialize the
obligations we are assuming in connection with the ConEd consent orders. In July
2000, in a draft of this Consent Order, the NYDEC alleged that we did not submit
revised Title V air permit applications on a timely basis after ConEd withdrew
its Title V applications for the Arthur Kill and Astoria facilities. We believe
that these allegations are incorrect and are contesting the imposition of any
penalties for such alleged violations.


  AIR POLLUTION CONTROL.

     Sulfur Dioxide.  The Clean Air Act provides for SO(2) emission reductions
to be achieved through a total cap on SO(2) emissions from affected units, and
an allocation of SO(2) "allowances" (each allowance authorizes the emission of
one ton of SO(2)). Units needing to cover emissions above their allocations can
buy allowances from sources that have excess allowances. Although we have
projected that the SO(2) allowances purchased and currently allocated to our
facilities will be in excess of predicted SO(2) emissions through the year 2009,
whether we will have an excess or deficit of SO(2) allowances for any given year
will depend, in part, on the capacity utilization of each of the facilities. If
necessary, we intend to comply with existing laws limiting SO(2) emissions by
purchasing additional allowances; however, depending on the extent of any
allowance deficits and the price and the availability of allowances for
purchase, we will consider changing to low sulfur coal, lower sulfur oil or the
installation of scrubbers. As discussed below, recent regulatory initiatives in
New York, Connecticut and Massachusetts may have an impact on our strategies
regarding SO(2) emissions reductions.


     Nitrogen Oxides.  Air quality in the northeastern region of the United
States is affected by air pollution transported within and into the region by
prevailing winds. In September 1994, 11 Northeastern states and the District of
Columbia signed a memorandum of understanding (the "MOU") establishing a
regional plan for reducing NO(x) emissions from utility and large industrial
boilers. NO(x) contributes to the formation of ozone. The 12 jurisdictions
signing this MOU fall within the Ozone Transport Region (the "OTR"), created
under the Clean Air Act in recognition of the regional ozone problem facing the
northeastern United States. In addition to the MOU, the EPA has issued a
regulation requiring 22 states in the eastern half of the United States to make
significant NO(x) emission reductions by May 1, 2003, and to subsequently cap
those emissions (the "SIP Call"). The NO(x) emissions reductions required by the
SIP Call are comparable to the reductions required by the MOU. By order of the
United States Court of Appeals for the District of Columbia Circuit, the
compliance date for the SIP Call has been extended until May 31, 2004.


     NO(x) regulations for New York, Massachusetts and Connecticut to implement
the MOU have been promulgated through the year 2002. New York, Massachusetts and
Connecticut have also promulgated regulations to implement the SIP Call and the
MOU for the years 2003 and beyond. Consistent with the MOU and the SIP Call,
emissions reductions are to be achieved through a cap on ozone season NO(x)
emissions from the largest sources of NO(x), including our facilities. Under
formulas established in the
                                       49
<PAGE>   56

regulations, each source will be allocated a number of "allowances," with each
allowance representing one ton of NO(x) that the source is allowed to emit. The
allowances can be bought and sold through a regional trading program similar to
the trading of SO(2) allowances established by the EPA pursuant to the Clean Air
Act. The extent of investment in control technologies, operational changes, and
allowance purchases required to comply with these regulations will be directly
related to the number of allowances our facilities receive and to the operation
of the facilities.

     Based on the regulations and the projected operation of the facilities, we
have projected that the NO(x) allowances to be allocated to the facilities will
be less than the projected NO(x) emissions from the facilities by the year 2003
and for subsequent years. Whether we will have an excess or deficit of NO(x)
allowances for any given year will depend, in part, on the capacity utilization
of each of the facilities. We are evaluating the installation of pollution
control equipment at the Somerset facility to implement the "Consumers First"
Agreement between MEC and the Attorney General for the Commonwealth of
Massachusetts that requires the Somerset facility to reduce NO(x) emissions at
Unit 6 to 0.15 lb./mmBtu by the year 2003. As part of this evaluation we are
considering the purchase of allowances and/or credits to meet the goals of the
Agreement. To the extent necessary, we intend to implement a strategic plan for
the purchase of NO(x) allowances and/or reduction of NO(x) emissions through the
installation of pollution control equipment. As discussed below, recent
regulatory initiatives of New York, Connecticut and Massachusetts may impact our
strategies regarding NO(x) emissions reductions.

     Public Policy Relating to Air Emissions.  On May 25, 2000, the New York
Department of Environmental Conservation issued a Notice of Violation to us and
the prior owner of our Huntley and Dunkirk facilities relating to physical
changes made at those facilities prior to our assumption of ownership. The
Notice of Violation alleges that these changes represent major modifications
undertaken without obtaining the required permits. Although we have a right to
indemnification by the previous owner for fines, penalties, assessments, and
related losses resulting from the previous owner's failure to comply with
environmental laws and regulations, if these facilities did not comply with the
applicable permit requirements, we could be required, among other things, to
install specified pollution control technology to further reduce air emissions
from the Dunkirk and Huntley facilities and we could become subject to fines and
penalties associated with the current and prior operation of the facilities.


     On October 14, 1999, Governor Pataki of New York announced that he is
ordering the NYDEC to require further reductions of SO(2) emissions and NO(x)
emissions from New York power plants, beyond that which is required under
current federal and state law. Under Governor Pataki's directive, NO(x)
emissions during the "non-ozone" season would be required to be reduced by 40%
from the Ozone Transport Commission's baseline levels. This additional reduction
requirement would be phased in between January 1, 2003 and January 1, 2007. In
addition, Governor Pataki announced that he is ordering a reduction of SO(2)
emissions by 50% beyond the requirements of the federal Acid Rain Program. These
reductions would also be phased in between January 1, 2003 and January 1, 2007.
The New York Department of Environmental Conservation is currently working on
draft regulations to implement Governor Pataki's initiative. Compliance with
these emissions reductions requirements, if they become effective, could have a
material impact on the operation of our facilities located in the State of New
York.



     On May 17, 2000, Governor Rowland of Connecticut issued an Executive Order
to the Connecticut Department of Environmental Protection ("CDEP") that requires
the CDEP to develop regulations, applicable to power plants and other major
sources of air pollution, to further reduce emissions of nitrogen oxides and
sulfur dioxide by May 2003. The Executive Order requires reductions of sulfur
dioxide by an amount that is 30% to 50% greater than current commitments and
reductions of nitrogen oxides that are 20% to 30% greater than current
commitments. In August 2000, the CDEP issued proposed regulations to implement
the Executive Order. With respect to sulfur dioxides, the CDEP proposes to phase
in new sulfur dioxide limitations beginning after December 31, 2001. The
regulation will ultimately require that after December 31, 2002, an operator of
a fossil fuel power plant will be required to either combust fossil fuel with a
fuel sulfur limit of equal to or less than 0.3% sulfur, by weight (dry basis),
or meet an average emissions rate of equal to or less than 0.3 lbs/mmBtu
calculated over an individual calendar month. The proposed regulation does allow
the operator to comply with the rule by meeting a higher limit if the operator
uses discrete emission

                                       50
<PAGE>   57


reduction credits or federal SO(2) allowances to offset the increased emissions.
The proposed regulation also requires operators of fossil fuel power plants, for
each calendar year commencing January 1, 2002, to retire federal SO(2)
allowances (by transferring such allowances to a general account established by
the CDEP) equal to the amount of sulfur dioxide, in tons, emitted by the
operator in the State of Connecticut. The allowances that can be used to satisfy
this requirement must have been issued to sources in Connecticut, or if
necessary, to sources in "affected states" (Rhode Island, Massachusetts, New
York, or sources within 50 miles from the location of the Connecticut source
relying on the allowance). With respect to nitrogen oxides, the CDEP has
proposed that sources subject to the Connecticut NO(x) Budget Program be
required to meet a 0.15 lbs/mmBtu emission standard for each October 1 through
April 30 period, commencing October 1, 2003. The CDEP has proposed to provide
flexibility by allowing subject sources to use NO(x) allowances or NO(x)
discrete emission reduction credits to offset any emissions in excess of the
proposed standard. We have been actively engaged in commenting on the CDEP's
regulations and are continuing to discuss the regulations with the CDEP. If,
however, the CDEP promulgates its proposed regulations as described above, these
regulations could have a material impact on our Connecticut facilities.



     The Commonwealth of Massachusetts is also seeking additional emissions
reductions beyond current requirements. The Massachusetts Department of
Environmental Protection has issued proposed regulations that would require
significant emissions reductions from certain coal-fired power plants in the
state, including our Somerset facility. The Massachusetts Department of
Environmental Protection has proposed that such facilities comply with stringent
limits on emissions of nitrogen oxides by December 1, 2003; on emissions of
sulfur dioxides commencing on December 1, 2003, with further reductions required
by December 1, 2005; and on emissions of carbon dioxide by December 1, 2005. In
addition to output-based limits (that is, a standard which limits emissions to a
certain rate per net megawatt hour), the proposed regulations also would limit,
by December 1, 2003, the total emissions of nitrogen oxides and sulfur dioxide
at the Somerset facility to no more than 75% of the average annual emissions of
the Somerset facility for the years 1997-1999. Finally, the proposed regulations
require the Massachusetts Department of Environmental Protection to evaluate, by
December 1, 2002, the technological and economic feasibility of controlling or
eliminating mercury emissions by the year 2010, and to propose mercury emission
standards within 18 months of completion of the feasibility evaluation.
Compliance with these proposed regulations, if such regulations become
effective, could have a material impact on the operation of our Somerset
facility. The annual average carbon dioxide emission rate identified in the
proposed regulations cannot be met by the Somerset facility.



     The Speaker of the New York City Council and other members of the Council
have introduced legislation that will require an agency designated by the Mayor
to establish an emissions standard for carbon dioxide that is no greater than
the emissions of carbon dioxide from electric generating units (with a capacity
of more than 25 megawatts) located in the City of New York in 1999 divided by
the electricity generated in the same year by said units. The proposed law would
require the standard to be reduced, each year, by one percent for each one
hundred megawatts of electric generating capacity installed within the City of
New York during the previous calendar year, until the carbon dioxide emission
standard has been reduced by 30%. The proposed law requires that the initial
carbon dioxide emission standard be established by March 1, 2002. Although the
proposed law, if enacted, could have an impact on the operation of our Arthur
Kill facility and on certain of our Astoria peaking units, we believe that,
relatively speaking, we are in a better position to comply with this proposed
law than many other generating units located in the New York City market.


     Particulate Matter.  A new ambient air quality standard was also adopted by
EPA in July 1997 to address emissions of fine particulate matter. It is widely
understood that attainment of the fine particulate matter standard may require
reductions in NO(x) and SO(2) emissions, although under the time schedule
announced by the EPA when the new standard was adopted, non-attainment areas
were not to have been designated until 2002 and control measures to meet the
standard were not to have been identified until 2005. However, in a May 14, 1999
decision, the D.C. Circuit remanded the standard to the EPA for further
justification. Accordingly, the impact, if any, of future revision to the fine
particulate matter ambient air quality standard on our facilities is uncertain
at this time.

     As a result of alleged violations of opacity, or visible emissions,
standards at the Huntley, Dunkirk and Oswego facilities, NiMo, the former owner
and operator of these facilities, was in the process of negotiating a
                                       51
<PAGE>   58


consent order with the NYDEC to resolve such violations at the time we acquired
these facilities. Under the terms of the asset purchase agreements, NiMo will be
responsible for any and all exceedances which occurred prior to the closing of
the transactions contemplated in the asset purchase agreements. We have agreed,
in connection with our acquisition of these facilities, to enter into separate
consent orders for each of these facilities, to address on-going and potential
future violations of opacity standards. We believe that the majority of the
opacity exceedances at the Dunkirk and Oswego facilities are non-preventable
events occurring as a result of startups and shutdowns at those facilities that
should not be subject to penalties under the New York regulations.


     Hazardous Air Pollutants.  The EPA is also evaluating whether to regulate
mercury emissions from coal-fired utility boilers. Because we do not know what
the EPA may require with respect to this issue, we are not able to evaluate the
impact of potential mercury regulations on the facilities that burn coal.
However, in 1999 the Dunkirk and Huntley facilities conducted coal sampling and
analysis as required by the EPA. Further, the Dunkirk facility was selected by
the EPA as a site where stack emissions sampling and analysis was to be
conducted. The stack sampling was completed in October, 1999. As noted above,
the Massachusetts Department of Environmental Protection has issued a proposed
regulation pursuant to which it will evaluate, by December 1, 2002, the
feasibility of regulating mercury emissions and will propose mercury emission
limits within 18 months of completing its feasibility report.

     Greenhouse Gases.  Since the adoption of the United Nations Framework on
Climate Change in 1992, there has been worldwide attention with respect to
greenhouse gas ("GHG") emissions. In December 1997, the Clinton Administration
participated in the Kyoto, Japan negotiations, where the basis of a Climate
Change treaty was formulated. Under the treaty, known as the Kyoto Protocol, the
United States would have an overall reduction target of 7% in GHG emissions from
1990 levels by 2008-2012. In 1997, the United States Senate passed a resolution
indicating that it would not ratify a GHG emissions reduction treaty that did
not involve commitments from developing nations to limit GHG emissions or one
that would damage the U.S. economy. To date, the Senate has not ratified the
Kyoto Protocol. We believe that as a result of curtailing emissions by operating
at reduced capacity factors, the anticipated repowering of existing generating
units and/or the replacement of such units with more energy efficient plants, we
will be in a good position to comply with GHG emission reduction requirements
should the U.S. Senate ratify the Kyoto Protocol.


     As noted above, the Massachusetts Department of Environmental Protection
has issued a proposed regulation that will require the Somerset Facility to meet
output-based carbon dioxide emission rate limits by December 1, 2005. According
to the Massachusetts Department of Environmental Protection, these limits are
intended to achieve a reduction of carbon dioxide emissions of 7% below 1990
emissions levels. However, we do not expect the annual average proposed carbon
dioxide rate limitation of 1600 lbs. per net MWh to survive through the draft
regulation stage. Also as noted above, the New York City Council has introduced
legislation to require the establishment of an "output-based" carbon dioxide
emission standard, commencing in 2002, that would decline over time as newer,
more efficient electric generating units are constructed in New York City.


  WATER POLLUTION CONTROL


     The major issue facing the facilities with respect to its wastewater
discharges is the potential for more stringent regulation of cooling water
intake structures. We have submitted a Final Action Plan to the NYDEC with
respect to the Arthur Kill cooling water intake structures. However, the NYDEC
Division of Fish, Wildlife & Marine Resources, in July 2000, disapproved our
Final Action Plan as not being in compliance with the Best Technology Available
standard required by New York regulations. The NYDEC's letter suggests that we
may need to install technology to reduce impingement and entrainment of aquatic
species by 99% or more. We have suggested a less costly alternative to respond
to the NYDEC's concerns, and are in discussions with the NYDEC about this
alternative. At the Somerset facility, we expect to be required to undertake
entrainment and possibly impingement studies in connection with the renewal of
our National Pollutant Discharge Elimination System permit, although the scope
of such studies has not been determined by the EPA. We also anticipate making
capital improvements to the cooling water intake structure at the Montville,
Dunkirk, Oswego, and Huntley facilities (depending on future operations at the
latter two

                                       52
<PAGE>   59

facilities). We have budgeted approximately $8 million (not including the
Huntley facility or any additional capital costs for cooling water intake
technology beyond that proposed in our Final Action Plan for the Arthur Kill
facility) in connection with water intake issues for the facilities.

     With respect to cooling water intake structures, the EPA is currently
required under a consent decree to propose draft regulations on or before July
1999 and promulgate final regulations by August 2001. The EPA has indicated that
it intends to seek an extension of these deadlines. These regulations will
address, among other things, regulatory approaches for determining what
constitutes adverse environmental impact and what constitutes the best
technology available for minimizing adverse environmental impact. It is not
possible to determine at this time how the EPA will resolve these issues. The
EPA's regulations in general and these determinations in particular may have a
material effect on the adequacy of our capital budgets relating to cooling water
intake structures.

  REMEDIATION

     Under various federal, state and local environmental laws and regulations,
a current or previous owner or operator of any facility, including an electric
generating facility, may be required to investigate and remediate past releases
or threatened releases of hazardous or toxic substances or petroleum products
located at the facility, and may be held liable to a governmental entity or to
third parties for property damage, personal injury and investigation and
remediation costs incurred by a party in connection with any releases or
threatened releases. These laws, including the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended by the Superfund
Amendments and Reauthorization Act of 1986, impose liability without regard to
whether the owner knew of or caused the presence of the hazardous substances,
and courts have interpreted liability under such laws to be strict and joint and
several. The cost of investigation, remediation or removal of substances may be
substantial. In connection with our ownership and operation of our facilities,
we may be liable for such costs.

     In connection with the divestiture of our facilities, the former owners of
the facilities undertook "Phase I" and "Phase II" environmental investigations
to evaluate the potential existence of contamination at the facilities and
whether remediation of such facilities would be required. A Phase I
environmental investigation typically involves a review of documents maintained
by the facility with respect to conditions at the facility; interviews with
facility personnel; review of governmental agency files; research into
historical operations at a facility; and a visual inspection of the facility. A
Phase II environmental investigation involves the collection and analysis of
samples from environmental media at a facility, with particular attention paid
to those areas of concern identified during the Phase I investigation.

     We believe that some remediation will be required at the Astoria and Arthur
Kill facilities. The Astoria facility is contaminated with liquid phase
petroleum products at the soil/groundwater interface. Sampling in the
groundwater at the Arthur Kill facility revealed elevated levels of certain
metals in the groundwater and surface water in certain areas of this facility.
We have assumed an obligation to address contamination at these two facilities
pursuant to a consent order previously executed by and between the NYDEC and the
former owner of these facilities, ConEd. We have budgeted $3.5 million for the
remediation work at the Astoria facility and $1.5 million for the Arthur Kill
facility. Finally, with respect to the Somerset facility, we have completed our
remedial work for the three areas of concern located on the Somerset facility
property in accordance with Massachusetts Department of Environmental Protection
regulations. We expect that we will be required to remove a limited amount of
contaminated materials from the property acquired in connection with our
purchase of the Somerset facility.


     In accordance with the requirements of the Connecticut Transfer Act, we
will be required to investigate and, if necessary, remediate existing
contamination found at the Devon, Norwalk, Montville, and Middletown facilities.
The Phase I and Phase II environmental assessments for these Connecticut
facilities revealed several contamination issues associated with fuel oil
storage tanks, ash ponds and ash disposal areas. However, we believe the only
significant concern with respect to these facilities relates to the on-site
placement of ash produced during the period when these facilities were
coal-fired. Testing of the ash has revealed relatively high concentrations of
arsenic, and samples of soils and groundwater in the vicinity of the ash
disposal areas have


                                       53
<PAGE>   60

indicated exceedances of Connecticut regulatory standards for arsenic and
certain other metals. We intend to undertake additional sampling and analysis to
demonstrate that, given the limited access to the areas of the stations impacted
by the ash, affirmative remedial actions (other than property use restrictions
designed to limit access to the facilities by trespassers) will not be required.
We have currently budgeted approximately $1.5 million to (1) complete
remediation and closure activities associated with the Connecticut Transfer Act
and (2) complete closure of former RCRA facilities at the Connecticut
facilities. If we are required to undertake certain affirmative remedial
actions, such as providing cover over areas impacted by the ash to prevent
exposure to the ash, the costs for completing the Connecticut Transfer Act
process could be significantly higher.

LABOR RELATIONS


     None of the operating employees at our facilities is an employee of NRG
Northeast or any guarantor. These operating employees are employed directly by
the respective subsidiary of NRG Operating Services that has contracted with the
guarantor to operate the facility. Many of the operating employees of the
respective operator subsidiaries were employed by the previous owner of that
facility. All of the facilities (other than the Middletown facility) are staffed
by a combination of union and non-union employees. The Middletown facility is
staffed completely by non-union employees. With respect to union employees, all
such employees are covered by current labor agreements with the relevant union,
which agreements have varying expiration dates. To date there are no unresolved
arbitrations filed by employees at any of our facilities.


INSURANCE

     We maintain insurance coverages that, in the opinion of an insurance
consultant, are sufficiently comprehensive in scope and consistent with, or
exceed, those normally carried by companies engaged in the same or similar
businesses and owning similar properties and operating in the same or similar
locations. The insurance program includes all-risk property insurance that
provides replacement value cover for all real and personal property, losses from
boiler and machinery breakdowns, and business interruption for large generating
assets. All of these policies are subject to certain sublimits. We also carry
general liability insurance covering liabilities to third parties for bodily
injury or property damages resulting from operations, automobile liability
insurance and excess liability insurance. Further, we have the benefit of title
insurance and workers' compensation insurance. Limits and deductibles in respect
of these insurance policies are comparable to those carried by other electric
generating enterprises with similar capital structures and owning and operating
facilities of like size and type as our facilities.

LEGAL PROCEEDINGS

     On or about July 12, 1999, Fortistar Capital Inc., a Delaware corporation,
filed a complaint in District Court (Fourth Judicial District, Hennepin County)
in Minnesota against NRG Energy, asserting claims for injunctive relief and for
damages as a result of NRG Energy's alleged breach of a confidentiality letter
agreement with Fortistar relating to the Oswego facility.

     NRG Energy disputed Fortistar's allegations and has asserted numerous
counterclaims. NRG Energy has counterclaimed against Fortistar for breach of
contract, fraud and negligent misrepresentations and omissions, tortious
interference with contract, prospective business opportunities and prospective
contractual relationships, unfair competition and breach of the covenant of good
faith and fair dealing. NRG Energy seeks, among other things, dismissal of
Fortistar's complaint with prejudice and rescission of the letter agreement.

     A temporary injunction hearing was held on September 27, 1999. The
acquisition of the Oswego facility was closed on October 22, 1999, following
notification to the court of Oswego Power's and NiMo's intention to close on
that date. On January 14, 2000, the court denied Fortistar's request for a
temporary injunction. In April, 2000, NRG Energy filed a summary judgment motion
to dispose of the litigation. A hearing on this motion has not yet been
scheduled. NRG Energy intends to continue to vigorously defend the suit and
believes Fortistar's complaint to be without merit. No trial date has been set.

                                       54
<PAGE>   61

     NRG Energy has provided an indemnity to the trustee and the holders of the
bonds with respect to the Fortistar Litigation. See "Description of Principal
Financing Documents -- Indemnification Agreement."

     On May 25, 2000, the New York Department of Environmental Conservation
issued a Notice of Violation to us and the prior owner of our Huntley and
Dunkirk facilities relating to physical changes made at those facilities prior
to our assumption of ownership. The Notice of Violation alleges that these
changes represent major modifications undertaken without obtaining the required
permits. Although we have a right to indemnification by the previous owner for
fines, penalties, assessments, and related losses resulting from the previous
owner's failure to comply with environmental laws and regulations, if these
facilities did not comply with the applicable permit requirements, we could be
required, among other things, to install specified pollution control technology
to further reduce air emissions from the Dunkirk and Huntley facilities and we
could become subject to fines and penalties associated with the current and
prior operation of the facilities.


     On May 31, 2000, FERC approved a request of the NY ISO, to impose price
limitations on one ancillary service, Ten Minute Non-synchronized Reserves, on a
prospective basis only, effective March 28, 2000, the date the NY ISO began
capping bids for that service. FERC rejected the NY ISO's request for authority
to adjust the market-clearing prices for that service on a retroactive basis. As
a result of the FERC order (unless the NY ISO or another party successfully
appeals the order), we will retain the approximately $8.0 million of revenues
collected in February 2000 and approximately $8.2 million included in revenues,
but not yet collected, for March 2000. The NY ISO has sought reconsideration of
the FERC order.

     Our members are NRG Eastern LLC and Northeast Generation Holding LLC, each
of which holds a 50% interest in us. We hold 100% of the ownership interest in
each of the guarantors. On the date of the issuance of the outstanding bonds,
our affiliate, NRG Connecticut, transferred its 100% ownership interest in the
Connecticut guarantors to us and we assumed certain debt to NRG Energy incurred
by NRG Connecticut in connection with the acquisition of the Connecticut
facilities. This debt to NRG Energy relating to the Connecticut facilities was
fully repaid from the proceeds of the issuance of the outstanding bonds. NRG
Energy, our indirect parent, owns a 100% interest in each of our members. Xcel
Energy (formerly Northern States Power Company) indirectly owns 82% of the stock
outstanding and 98% of the combined voting power of NRG Energy's common stock
and class A common stock. See "NRG Northeast, NRG Energy and Xcel Energy."


POWER SALES AND AGENCY AGREEMENTS

     Each guarantor has entered into a power sales and agency agreement with NRG
Power Marketing, a wholly-owned subsidiary of NRG Energy, pursuant to which NRG
Power Marketing will provide services in the areas of managing, marketing and
selling the guarantors' energy and capacity; managing and procuring the
guarantors' fuel requirements; and managing the guarantors' emissions
allowances. See "Summary of Certain Principal Agreements."

                    SUMMARY OF CERTAIN PRINCIPAL AGREEMENTS

     The following is a summary of certain principal agreements related to our
facilities and our business and that of the guarantors, and it is not a full
statement of the terms of such agreements. Accordingly, the following summaries
of such agreements are qualified by reference to each agreement and are subject
to the terms of the full text of each agreement. Unless otherwise stated, any
reference in this prospectus to any agreement will mean such agreement and all
schedules, exhibits and attachments thereto as amended, supplemented or
otherwise modified and in effect as of the date hereof. Copies of all of these
agreements have been filed as exhibits to the registration statement of which
this prospectus forms a part. See "Where You Can Find More Information."

POWER SALES AND AGENCY AGREEMENTS

     SCOPE.  NRG Power Marketing has entered into power sales and agency
agreements with each of the guarantors for terms of approximately 30 years from
various execution dates. NRG Power Marketing will have the exclusive right and
obligation to effect the direction of the power output from the facilities. In
addition, pursuant to these agreements, NRG Power Marketing will (i) have the
exclusive right to manage, market and sell all power not otherwise sold or
committed by the guarantors, (ii) procure and provide to the guarantors all fuel
requirements required to operate their respective facilities and (iii) provide
emissions management services to the guarantors for the tracking, procurement,
sales and allocation of emissions allowances, and will also assist in performing
analyses comparing the costs of installing and operating environmental control
equipment to emissions allowance procurement. The guarantors must make all
commercially reasonable efforts in accordance with good utility practice to make
such power available to NRG Power Marketing at each agreed delivery point. In
the event the guarantor delivers less than the expected amount of power to the
delivery point, the guarantor will refund NRG Power Marketing for the amount of
any overpayment plus interest from the date of such overpayment until the amount
is paid in full. Also, NRG Power Marketing will assist the facilities in
performing all of the guarantors' obligations under the transition power sales
contracts.

     PAYMENT.  NRG Power Marketing will pay to each guarantor the "Net Power
Revenue" from its sales of power pursuant to the agreement. Net Power Revenue is
defined as the gross receipts for sales of power by NRG Power Marketing less (i)
payments by NRG Power Marketing to the guarantor pursuant to any of the
transition power sales contracts; (ii) transmission and other delivery costs;
(iii) any taxes paid by NRG Power Marketing in connection with the sale of
power; and (iv) any other costs incurred in connection with the sale of power,
including an arms-length, commercially reasonable allocation of overhead and
administrative costs. The guarantor will pay to NRG Power Marketing the costs of
fuel provided to the guarantor by NRG Power Marketing. In addition, NRG Power
Marketing will pay to the guarantor any amounts received for the sale of
emissions allowances provided by the guarantor to NRG Power Marketing and the
guarantor will pay to NRG Power Marketing any amounts due for the purchase of
emissions allowances from NRG Power Marketing.

     If either party fails to make a payment when due, such overdue payment will
accrue interest at a rate of 2% from the due date until the date of payment. In
addition, if NRG Power Marketing is in default on a payment for power for 30
days after notice of such default, the guarantor may (i) suspend NRG Power
Marketing's responsibility for bidding and scheduling such guarantor's power
into the power pool; (ii) sell power into the power pool or to another power
marketer; (iii) terminate the agreement; or (iv) exercise any other remedy it
has available in law or equity with respect to such default.

     INDEMNIFICATION AND LIMITATION OF LIABILITY.  Title and risk of loss
related to the power procured by NRG Power Marketing will transfer to NRG Power
Marketing at a mutually agreed-upon delivery point. Each party will indemnify
the other for harm suffered arising from any act or incident occurring during
the period when control and title to the power is vested in the indemnifying
party, as designated by the delivery point.

     TERM.  The agreements terminate on December 31, 2030.

     ASSIGNMENT.  The agreements may not be assigned without the prior written
consent of the other party; provided, however, either party may, without the
consent of the other party (i) transfer, sell, pledge, encumber

                                       59
<PAGE>   66

or assign the agreement or the accounts, revenues or proceeds hereof in
connection with any financing or other financial arrangements by or for the
benefit of the guarantor or NRG Northeast, (ii) transfer to a creditworthy
affiliate whose ability to perform its obligations is not materially different
from the transferring or assigning party, (iii) transfer to a person acquiring
all, or substantially all, the assets of a party, or (iv) in the case of the
guarantors, transfer to a person acquiring the entire facility; provided,
however, that in each case, except an assignment pursuant to clause (i) above,
the assignee must provide written consent to the terms and conditions of the
agreement and such assignee's creditworthiness and technical ability to perform
its obligations must not be materially different then that of the assignor.

     ASSIGNMENT TO ISSUER.  On the date of the issuance of the outstanding
bonds, each guarantor, with the consent of NRG Power Marketing, assigned its
rights to receive revenues under its respective power sales and agency agreement
(including rights in respect of the transition power sales contract attributable
to its facility) to NRG Northeast, such revenues to be used by NRG Northeast in
accordance with the funds administration agreement entered into by NRG Northeast
and the guarantors. This assignment may be terminated by any guarantor with
respect to its revenues upon 30 days written notice to NRG Power Marketing.

OPERATION AND MAINTENANCE AGREEMENTS

     SCOPE.  Each of the guarantors has entered into an operation and
maintenance agreement with a facility-specific subsidiary operator of NRG
Operating Services (other than the guarantors which own the Connecticut Jet and
Middletown facilities, which share an operator).

     Each operator will perform all administrative, operation and maintenance
work at its respective facility, including:

     - coordinating the fuel delivery, unloading and inventory;

     - developing a spare parts and inventory program;

     - meeting external performance standards for transmission of electricity;

     - providing operating and maintenance consulting to the guarantors as the
       guarantors may deem necessary and desirable;

     - performing and recording periodic operational tests of the facility
       equipment scheduled by NRG Power Marketing in accordance with the NEPOOL
       or the NYPP requirements, the manufacturer's specifications, legal
       requirements, environmental guidelines and other established guidelines;

     - cooperating with and assisting the guarantors in performing the
       guarantors' obligations under agreements related to each facility;

     - assisting its respective guarantor in preparing the budgets, including
       providing operating budgets, rolling five year forecasts and providing
       notice to the respective guarantor that the operating expenses exceed or
       are expected to exceed the approved operating budget; and

     - disposing of all waste material in accordance with legal requirements and
       the guarantor's waste disposal arrangements, if any.

     PAYMENT.  The base fee to be paid to each operator varies by facility
ranging from $300,000 to $750,000 per calendar year. The fee is not subject to
escalation during the term of the agreement. There are also incentive fees and
penalties based on performance under the approved operating budget, the heat
rate and safety. There are caps on both the incentive fees and penalties which
vary by facility. Each operator will be reimbursed for usual and customary
demobilization costs and severance costs, if any, if a guarantor elects not to
renew. Each guarantor will also fund an operating account for current and
reasonably-projected short-term operating costs.

     INDEMNIFICATION AND LIMITATION OF LIABILITY.  To the extent not otherwise
covered by facility insurance, each party will indemnify and hold harmless the
other party for any damages incurred as a result of a breach of the agreement by
the indemnifying party, unless, however, such damage is incurred as a result of
the gross

                                       60
<PAGE>   67

negligence or misconduct of the indemnified party. The liability of either party
to the other for any and all losses incurred in connection with the agreement,
will in no case exceed five times the base annual operator fee.

     TERM.  Each agreement is effective for a term of five years beginning the
execution date of the agreement. The agreements are automatically renewed for
successive five year terms if the parties do not provide termination notice 180
days prior to the end of each term. A guarantor may terminate its respective
agreement at any time if it gives 6 month's notice and pays the present value of
the operator's fees for the remaining term discounted at prime plus 6%, plus the
customary demobilization costs.

     ASSIGNMENT.  The agreement may not be assigned without the prior written
consent of the other party unless such assignment (i) is in connection with a
financing by or for the benefit of the guarantor or NRG Northeast; (ii) is to a
creditworthy affiliate; (iii) to a person acquiring all, or substantially all,
the assets of a party; or (iv) in the case of the guarantor, to a person
acquiring the facility; provided, however, that in each case, except an
assignment pursuant to clause (i) above, the assignee must provide written
consent to the terms and conditions of the agreement and such assignee's
creditworthiness and technical ability to perform its obligations must not be
materially different than that of the assignor.

     PENDING RENEGOTIATION.  We intend to replace the existing operation and
maintenance agreements following renegotiation of their terms with NRG Operating
Services on behalf of the operators. Issues currently under discussion include
the amount of the annual fee payable to each operator, the current provisions in
the agreements for liquidated damages payable by the operators in the event
certain operating targets are not met, the appropriate targets to be set and the
basis for calculation of these targets. We expect that replacement of these
agreements will result in higher operating costs for the guarantors but will not
have a material adverse effect on NRG Northeast and the guarantors, taken as a
whole.

CORPORATE SERVICES AGREEMENTS

     SCOPE.  NRG Energy has entered into separate but identical agreements with
each guarantor pursuant to which NRG Energy will provide services in support of
the operations of the respective facilities. NRG Energy has agreed to provide,
on an as requested basis, any work, direction of work, technical or commercial
information, data, consulting, staff augmentation or any other corporate
business function performed for or on behalf of the guarantor or the operator,
as the case may be, by NRG Energy in functional areas such as, but not limited
to: human resources, accounting, finance, treasury, tax, office administration,
information technology, engineering, construction management, environmental,
legal and safety. The standard of performance for the services is with
reasonable diligence and dispatch in a prudent, cost effective and efficient
manner, in accordance with all applicable laws. NRG Energy may provide the
personnel to perform such services, in its sole discretion, or elect to have
these services performed by a third party, but NRG Energy will be ultimately
responsible for the services.

     PAYMENT.  NRG Energy will be paid for the personnel time and other costs
associated with performing the services, including transportation or relocation
costs of personnel; miscellaneous expenses; reproduction costs; cost of any
permits, fees, licenses or royalties; and premiums and brokerage fees on all
bonds and insurance policies required.

     WARRANTY AND LIMITATION OF LIABILITY.  NRG Energy warrants that the
services performed under the corporate services agreements will be in accordance
with accepted professional standards and practices. The sole and exclusive
remedy for breach of this warranty will be for NRG Energy to re-perform the
portion of the defective service. All costs of any re-performance will be
reimbursed by the guarantor to NRG Energy but NRG Energy will receive no
additional profit thereon. NRG Energy's legal liability under the agreement will
not exceed the value of its services performed during the calendar year prior to
the cause giving rise to or creating any such liability.

     TERM.  The term of the agreements commenced on the date of the execution of
the agreement and continues until terminated in writing by the guarantor. If
either party fails to perform its obligations or

                                       61
<PAGE>   68

becomes subject to bankruptcy, an event of default will occur and the
non-defaulting party may elect to suspend or terminate the agreement upon notice
to the other party.

     ASSIGNMENT.  Neither party may assign its rights or obligations under the
agreement without the consent of the other party. However, NRG Energy, in its
sole discretion, may cause an affiliate or third-party provider to perform any
of the services required by NRG Energy.

TRANSITION POWER SALES CONTRACTS

     For the first four years of the term of the bonds, we expect to sell a
significant portion of our power pursuant to transition power sales contracts
entered into between each guarantor or NRG Power Marketing, and the former
owners of the facilities. The transition power sales contracts for each of the
guarantors is described in more detail below.

     ARTHUR KILL AND ASTORIA TRANSITION CAPACITY AGREEMENTS.  Arthur Kill Power
and Astoria Power have entered into agreements with ConEd that obligate them, as
sellers, to maintain the electric generating capability and availability of
their respective facilities at specified levels for the terms of these
agreements, and whereby during certain periods, Arthur Kill Power and Astoria
Power have agreed to sell to ConEd at a fixed price up to 100% of the capacity
of each of the Arthur Kill and Astoria facilities, as long as the capacity is
counted in the installed capacity requirement for New York. The capacity must
satisfy all criteria, standards and requirements applicable to providers of
installed capacity established by the New York State Reliability Counsel
("NYSRC"), the Northwest Power Coordinating Council ("NPCC"), the North American
Electric Reliability Council ("NERC"), the NYPP or the NY ISO. Should the
capacity of the facility drop below the minimum level required, the guarantor
owning the facility will pay to ConEd a deficiency charge. The sellers may use
electric capacity other than that generated by their own plants to satisfy
ConEd's demands.

     The guarantors will bill ConEd for the electricity capacity sold and ConEd
will bill the guarantors for any capacity deficiency payments on a monthly
basis. Any amount unpaid after it is due will accrue interest. Any dispute on
the amount payable will first be settled by good faith negotiation among the
parties

     The agreements expire on the earlier of (i) December 31, 2002 or (ii) the
date on which Arthur Kill Power or Astoria Power receives written notice from
the NY ISO indicating that none of the electric capacity of the specified
facility is required for meeting the installed capacity requirements in New York
City.

     DUNKIRK AND HUNTLEY SWAPTION ARRANGEMENT.  For the first four years of the
term of the bonds, we estimate that a significant portion of the total revenues
from the Dunkirk and Huntley facilities will be derived from four-year
transition power sales contracts for capacity and energy. Under these
agreements, NRG Power Marketing, acting on behalf of Dunkirk Power and Huntley
Power, has agreed to sell to NiMo 100% of the capacity of the Dunkirk and
Huntley facilities, and an option to purchase up to 39% of the annual energy
output from the Dunkirk facility and 45% of the annual energy output from
certain units of the Huntley facility. We currently anticipate that energy not
sold to NiMo during the transition period will be sold to the NY ISO. Each of
the following agreements was executed on June 11, 1999 and extends for a term of
four years from the closing date of the asset purchase.

     MASTER SWAP AGREEMENT.  To hedge its transition to market rates, NiMo has
required NRG Power Marketing to enter into the ISDA Master Agreement (together
with the Schedule, the Confirmation and the Guarantee Agreement, the "Swap
Agreement"). Under the Swap Agreement, NiMo will pay to NRG Power Marketing a
fixed monthly price for the Dunkirk (units 1, 2, 3 and 4) and Huntley (units 67
and 68 only) facilities' capacity and ancillary services and NRG Power Marketing
will pay to NiMo the market rates for the related capacity and ancillary
services. The swap is only a financial contract and it incorporates the terms of
the ISDA Master Agreement.

     NiMo will have the right from time to time to exercise a call option for an
additional swap pursuant to which, within a certain limit consistent with
outages and availability requirements, NiMo will nominate certain amounts of
energy from the Dunkirk and Huntley facilities and will pay to NRG Power
Marketing an amount for such energy determined in accordance with the heat rate
curve representing the nominated unit.

                                       62
<PAGE>   69

NRG Power Marketing will pay to NiMo the market rates for such energy at the
time that the energy was nominated. However, NRG Power Marketing may refuse the
call option for either of the facilities if a facility is unexpectedly forced
off-line or derated sufficiently to be unable to fulfill the portion of the
specified quantity of power in the option. Any such refusal of the call option
will be limited to the Decline Quantity Cap, which is calculated based upon the
capacity of the relevant facility for the prior six months. NiMo will be
entitled to make up for any refused call option in the future by delivering
reasonable notice to NRG Power Marketing.

     TRANSITION POWER PURCHASE AGREEMENT (HUNTLEY 65 OR 66 -- SECONDARY
CALL).  Huntley Power has entered into an agreement with NiMo that gives NiMo
the option to purchase from the Huntley facility certain quantities of
electricity generated by the Huntley units 65 and 66, during the summer and
winter months, up to a specified maximum limit for the term of this agreement.
If Huntley Power is selling the electrical output generated by units 65 and 66
to a third party, Huntley Power may refuse to deliver such output to NiMo.
Furthermore, if unit 65 or 66 is generating for NiMo, Huntley Power has the
right to "recall" the unit(s) in order to facilitate a sale to a third party. If
Huntley Power fails to meet NiMo's quantity request for electricity output, it
will compensate NiMo. NiMo will pay Huntley Power according to the amount of
electricity output delivered to NiMo, on a monthly basis. Control and title pass
at the point of delivery of the energy and each party agrees to indemnify the
other against any claims arising out of any act or incident occurring during the
period when control and title of the electricity is vested in the indemnifying
party. Neither party may assign the agreement without the written consent of the
other party, except assignments in connection with any financing, to certain
qualified affiliates and in connection with any transfer of substantially all
the assets of such party.

     TRANSITION POWER PURCHASE AGREEMENT (HUNTLEY POWER LLC -- CALL).  Huntley
Power has entered into an agreement with NiMo that gives NiMo the option to
purchase from Huntley Power certain quantities of electricity generated by
Huntley units 67 or 68 (during peak and off-peak summer hours), within a
specified range of MW per hour, not to exceed 189 MW for any one hour during the
peak hours, for the term of the agreement. If Huntley Power fails to meet NiMo's
quantity request for electricity, Huntley Power will compensate NiMo for
quantities not provided. NiMo will pay Huntley Power according to the amount of
power delivered to NiMo, on a monthly basis. Control and title passes at the
point of delivery of the energy and each party will indemnify the other party
from any claims arising out of any act or incident occurring during the period
when control and title of the electricity is vested in the indemnifying party.
Neither party may assign the agreement without the written consent of the other
party, except assignments in connection with any financing, to certain qualified
affiliates and in connection with any transfer of substantially all the assets
of such party.

     OSWEGO TRANSITION POWER AGREEMENT.  Oswego Power has entered into a
four-year transition power sales contract with NiMo in order to hedge its
transition to market rates. Under the agreement, NiMo will pay to Oswego Power a
fixed monthly price plus start up fees for the right, but not the obligation, to
claim, at a specified delivery point or points, the installed capacity of unit 5
of the Oswego facility, for the right to exercise, at a specified price, an
option for 40% of the installed capacity of unit 6, and for the right to
exercise, at a specified price, an option for an additional 350 MW of installed
capacity from both units. The total amount of energy which Oswego Power must
supply under the call option is limited to a nominal amount of energy per year.
Oswego Power may refuse such option if the facility is unexpectedly unavailable
or derated sufficiently to be unable to fulfill the option, as long as Oswego
Power uses "good utility practice" to maintain the power stations. Oswego Power
may also choose to supply the energy required from another source as long as
adjustment is made for any difference in value between the agreed upon delivery
point and the actual point of delivery. In the event that Oswego Power is unable
to provide from its own sources installed capacity of unit 5 in the amount
claimed by NiMo, Oswego Power must procure the capacity from the market and
provide it to NiMo at no additional cost or else suffer a penalty. Each party
has agreed to indemnify the other party for any claims occurring while the other
party has control of the power. No party may assign the agreement without the
prior written consent of the other party except to an affiliate or in connection
with a merger or consolidation. The term of the agreement is for four years from
the closing date of the asset sale.

     SOMERSET WHOLESALE STANDARD OFFER SERVICE AGREEMENT.  NRG Power Marketing,
acting on behalf of Somerset Power, has entered into a Wholesale Standard Offer
Service Agreement, dated October 13, 1998
                                       63
<PAGE>   70

and amended as of January 15, 1999 (the "WSO Agreement"), with Blackstone Valley
Electric Company, Eastern Edison Company, and Newport Electric Corporation
(collectively the "EUA Companies"), which obligates NRG Power Marketing to
provide each of the EUA Companies with firm all-requirements electric service,
including capacity, energy, reserves, losses and related services necessary to
serve approximately 30% of the EUA Companies' aggregate load attributable to
retail customers taking standard offer service which we estimate to be
approximately 275 MW at peak requirement. The difference between the EUA
Companies' service requirements and the Somerset facility's operational capacity
will be made up by a combination of power supplied by facilities owned by our
other guarantors and purchased power. NRG Power Marketing assumes all expenses,
liabilities and losses, regulatory or economical, related to such service. NRG
Power Marketing may supply the power to the EUA Companies at any point on the
NEPOOL transmission facilities system or on the EUA Companies' system.

     The price for each unit of electricity is a combination of a fixed price
plus a fuel adjustment factor. The EUA Companies will calculate the estimated
power supplied each month and pay to NRG Power Marketing the price for such
electricity before the end of the next month. Any amounts unpaid by the due date
will accrue interest. The EUA Companies may make retroactive adjustments to the
bills for up to one year after the date of the original billing. NRG Power
Marketing must meet certain creditworthiness criteria for the term of the
agreement, or must provide a guaranty from an entity which meets the
creditworthiness criteria. The term extends from April 26, 1999, the closing
date of the asset purchase agreement until December 31, 2009. The agreement may
also be terminated in the case of an event of default or if the facility's
electric service requirement is less than 1 MW/hr for two consecutive months.

     No party may assign the agreement without the prior written consent of the
other party except to an affiliate or in connection with a merger or
consolidation. Each party has agreed to indemnify the other party for all
damages or liabilities arising out of the wrongful acts or omissions by the
employees or agents of the indemnifying party unless caused by an act of
negligence or willful misconduct by the indemnified party.

     CONNECTICUT FACILITIES STANDARD OFFER SERVICE WHOLESALE SALES
AGREEMENT.  NRG Power Marketing has entered into a standard offer service
wholesale sales agreement with CL&P pursuant to which NRG Power Marketing will
supply CL&P at fixed prices a specified share of a portion of CL&P's aggregate
retail load. The quantity of power to be supplied is equal to 35% of CL&P's
standard offer service load during calendar year 2000, 40% during calendar years
2001 and 2002 and 45% during calendar year 2003. We estimate that 45% of CL&P's
standard offer service load in 2003 will be approximately 2,000 MW at peak
requirement.

     NRG Power Marketing is responsible for delivering the contracted power to a
mutually agreed upon delivery point, at which point title to and liability for
the electricity passes to CL&P. NRG Power Marketing is also responsible for
forecasting for the purposes of meeting its supply obligation and for all ISO
and NEPOOL charges and expenses in connection with the delivery of power. CL&P
is responsible for arranging all delivery services for electricity from the
delivery point to retail customers.

     The agreement also requires NRG Power Marketing to either (i) be a member
of the NEPOOL or (ii) have a contract with a member of the NEPOOL for the
duration of the term of the agreement which commences on January 1, 2000 and
expires on December 31, 2003.

     No party may assign the agreement without the prior written consent of the
other party except to an affiliate or in connection with a merger or
consolidation. Each party has agreed to indemnify the other party for all
damages or liabilities arising out of the wrongful acts or omissions by the
employees or agents of the indemnifying party unless caused by an act of
negligence or willful misconduct by the indemnified party.

FUNDS ADMINISTRATION AGREEMENT

     On the date of the issuance of the outstanding bonds, NRG Northeast and the
guarantors entered into a funds administration agreement, pursuant to which each
guarantor will assign its right to receive revenues under the power sales and
agency agreement to which it is a party to NRG Northeast and NRG Northeast

                                       64
<PAGE>   71

will agree to perform accounting, tax and treasury functions for each guarantor.
NRG Northeast agrees that it will use these funds to pay expenses of each
guarantor, including the following:

     - operating expenses;

     - payments in connection with permitted indebtedness;

     - capital expenditures; and

     - other payments as directed by each guarantor.

     Any funds remaining after making the foregoing payments will be disbursed
by NRG Northeast, as directed in writing by each guarantor, or held by NRG
Northeast until it receives written direction from each guarantor.

     At the present time each guarantor has directed that any such remaining
funds be retained by NRG Northeast for its own account.

     Any guarantor may terminate this funds administration agreement with
respect to itself upon 30 days' written notice to NRG Northeast.

INTERCONNECTION AGREEMENTS

     Each of the guarantors has entered into a long-term interconnection
agreement with the utility from which it acquired its facility. Pursuant to such
interconnection agreements, the selling utility's transmission system will
remain interconnected with the guarantor's facility, which interconnection
facility will be operated by the utility at the guarantor's expense. The selling
utility typically has discretion to determine whether, when and in what manner
replacements or upgrades to the interconnection facility will be installed.
These interconnection agreements typically require that each guarantor's
facility conform to the selling utility's operational requirements. If
relocation, rearrangement or abandonment of the interconnection facility is
necessitated by practical, economical or governmental reasons, either party will
promptly inform the other party and the applicable guarantor will bear the costs
of relocation or modification of the interconnection facility.

     The selling utility typically owns and maintains, at the guarantor's
expense, a metering system to calculate the amount of electricity transferred.
Each guarantor is typically required to provide reactive capability to regulate
and maintain system voltage at the delivery point. Each guarantor is also
responsible for the proper coordination of any applied under/over frequency
generator tripping and for maintenance of the operating voltage within a certain
range.

     Each party is required to fully indemnify the other party as to its own
actions. Should any interconnection agreement be at variance with any laws,
regulations or ordinances, the relevant party is required to notify the other
party and the parties will negotiate in good faith to comply with the law.

     These interconnection agreements are typically long-term agreements having
terms ranging from 20 years up to the time of retirement of the facility, unless
terminated earlier in accordance with the terms of the applicable agreement.

SITE AGREEMENTS

     Each of the guarantors has entered into a site agreement with the utility
from which it acquired its facility, which clarifies the ownership of different
assets at the facilities and the continuing responsibilities and obligations
that each party has to the other with respect to access to, use of, and services
to be provided for and with respect to the property, assets and facilities of
the other.

     SITE ACCESS.  Under the site agreements, each guarantor typically grants
the selling utility access to parts of the electric generating assets acquired
by the guarantor, while the selling utility grants to the guarantor access to
parts of the transmission and distribution assets retained by the selling
utility. In order to conduct its business, each party is granted permanent
easements for access to and maintenance of its own facilities,

                                       65
<PAGE>   72

systems and equipment, located on or in the property or the facilities of the
other. Each party is also required to grant reasonable access to all of its
properties and facilities as may be necessary to enable the other party to
maintain its respective facilities, systems, equipment, and property or, with
respect to the easement granted to the selling utility, to perform any required
environmental remediation on the guarantor's site.

     MAINTENANCE.  Each party will cooperate in providing routine maintenance to
all the facilities. Generally, for essential structures, the party owning such
structures is obligated to maintain them pursuant to good utility practice and
prepare and deliver a written report on the condition of such structure to the
other party. The selling utility has the right to operate certain of the
guarantor's systems and equipment that are essential to its transmission and
distribution system should the guarantor or its successor fail, upon notice and
an opportunity to cure, to operate such vital systems and equipment. Each party
may also construct new facilities, or modify or alter any facility, system or
equipment that is subject to the site agreement.

     INFORMATION AND COOPERATION.  The site agreements generally require a
guarantor to provide the information needed for operation, maintenance and
planning of the selling utility's transmission or distribution system. In
addition, each guarantor is often required to cooperate with the selling utility
in any investigation of any disturbance to or mis-operation of the transmission
or distribution system. Each party is required to promptly provide the other
with any notice of safety issues that may have an immediate adverse effect on
the other party's facilities, system or equipment.

     ANCILLARY SERVICES AND INSURANCE.  Each party is obligated to provide the
other with certain local services, and with such current, potential, metering
and contact outputs as are required for the operation of protection and control
systems. Each party is also obligated to provide to the other party all data
with respect to remote terminal units. Each party will maintain sufficient
insurance and provide regular notice of coverage to the other party. Each party
will be named as additional insured on the general liability insurance policies
of the other party.

     TERM.  The site agreements typically have very long terms, generally from
40 years up to the time of retirement of the facility.

PURCHASE AND SALE AGREEMENTS

     NRG Energy entered into purchase and sale agreements with NiMo, ConEd,
CL&P, MEC and RG&E for the purchase of the guarantor facilities. The rights and
obligations of NRG Energy under the agreements have been assigned to, and
assumed by, each of the guarantors in respect of its facility pursuant to
certain assignment and assumption agreements.

     Generally all the representations, covenants and warranties contained in
these agreements expired and were terminated upon the closing of the asset
sales. However, certain of the indemnification obligations (which have been
assumed by each guarantor in respect of its facility), including indemnification
of certain claims (including environmental claims) brought by third parties,
survive the applicable date of the issuance of the outstanding bonds for up to
18 months.

                            DESCRIPTION OF THE BONDS

     The terms of the bonds we are issuing in this exchange offer and the
outstanding bonds are identical in all material respects, except:

     - the bonds issued in the exchange offer will have been registered under
       the Securities Act;

     - the bonds issued in the exchange offer will not contain transfer
       restrictions and registration rights that relate to the outstanding
       bonds; and

     - the bonds issued in the exchange offer will not contain provisions
       relating to the payment of liquidated damages to be made to the holders
       of the outstanding bonds under circumstances related to the timing of the
       exchange offer.

     Any outstanding bonds that remain outstanding after the exchange offer,
together with bonds issued in the exchange offer, will be treated as a single
class of securities under the indenture for voting purposes. When we refer to
the term "bond" or "bonds", we are referring to both outstanding bonds and the
bonds to be issued in the exchange offer. When we refer to "holders" of the
bonds, we are referring to those persons who are the registered holders of bonds
on the books of the registrar appointed under the indenture.

     The following is a description of certain provisions of the bonds offered
in this prospectus. The following information does not purport to be a complete
description of the bonds and is subject to, and qualified in its entirety by,
reference to the bonds and the indenture. Unless otherwise specified, the
following description applies to all of the bonds. For purposes of this section,
references to the "NRG Northeast", "us", "we" or "our" do not include the
guarantors.

GENERAL

     The outstanding bonds were issued and the bonds will be issued pursuant to
an indenture, as supplemented by the first supplemental indenture, dated as of
February 22, 2000, by and among NRG Northeast, the guarantors and The Chase
Manhattan Bank, as trustee, in the United States in a private transaction, and
outside the United States in an offering pursuant to Regulation S under the
Securities Act, none of which is subject to the registration requirements of the
Securities Act. The terms of the bonds include those stated in the indenture and
those made part of the indenture by reference to the Trust Indenture Act. The
bonds are senior secured obligations and rank senior in right of payment to all
of our existing and future indebtedness that is designated as subordinate or
junior in right of payment to the bonds.

THE GUARANTEES

     The bonds are jointly and severally guaranteed by all of our existing and
certain future subsidiaries. The obligations of the guarantors under their
guarantees are limited as necessary to minimize the risk that such guarantees
would constitute a fraudulent conveyance under applicable law. See "Risk
Factors -- Federal and state statutes allow courts, under specific
circumstances, to void subsidiary guarantees and require holders of bonds to
return payments received from guarantors."


     The guarantees of the bonds: (i) are senior obligations of the relevant
guarantor; and (ii) are equal in right of payment to all of the relevant
guarantor's indebtedness, which is restricted to intercompany notes.


     As of the date of this prospectus, all of our subsidiaries are guarantors
subject to the restrictive covenants of the indenture and the obligations under
the security agreement. However, under certain circumstances we will be
permitted to designate certain of our subsidiaries as "unrestricted
subsidiaries" which will not be subject to the restrictive covenants in the
indenture or the obligations under the security agreement. See "Description of
Principal Financing Documents -- Indenture -- Covenants of NRG
Northeast -- Certain Obligations Respecting Subsidiaries."

NATURE OF RECOURSE

     Recourse for payment or performance of any of our obligations in respect of
the bonds will be limited solely to us and the guarantors (other than to the
extent NRG Energy provides a debt service reserve support instrument). Neither
any of our affiliates (other than the guarantors or NRG Energy to the extent it
provides a debt service reserve support instrument) nor any of our officers,
directors and stockholders or the officers, directors and stockholders of any of
our affiliates will be liable for the payment of the principal of, premium, if
any, or interest on the bonds, and holders of the bonds will have no claim
against or recourse to (whether by operation of law or otherwise) such entities
or persons or their affiliates.

RANKING

     The bonds constitute our senior secured obligations and rank senior in
right of payment to all of our existing and future indebtedness that is
designated as subordinate or junior in right of payment to the bonds. The bonds
are fully and unconditionally guaranteed by each guarantor and secured by our
membership interests in the guarantors, our rights under intercompany notes with
the guarantors, the power sales and agency agreements, the operation and
maintenance agreements, the corporate services agreements and the transition
power sales contracts, the debt service reserve account and the revenues from
the power sales contracts entered into by NRG Power Marketing. The obligations
of each guarantor under the guarantees constitute senior unsecured debt of the
relevant guarantor. As a result, the bonds and guarantees rank equally with all
the senior debt of NRG Northeast and that of the guarantors, and rank senior to
all other indebtedness of NRG Northeast and the guarantors.

RATINGS

     Moody's has assigned the bonds a long-term senior secured debt rating of
"Baa3" and S&P has assigned the bonds a long-term senior secured debt rating of
"BBB-". These expectations reflect only the views of Moody's and S&P,
respectively, at the time the rating is issued, and any explanation of the
significance of these ratings may be obtained only from the respective rating
agency. There is no assurance that these ratings will remain in effect for any
given period of time or that these ratings will not be lowered, suspended or
withdrawn entirely by Moody's or S&P if, in their judgment, circumstances so
warrant. Any lowering, suspension or withdrawal of these ratings may have an
adverse effect on the market price or marketability of the bonds.

REDEMPTION AND REPURCHASE

  MANDATORY REDEMPTION

     The bonds will be subject to mandatory redemption in whole or in part in
the event we receive casualty insurance proceeds or condemnation proceeds, as
applicable, in respect of any loss or damage to or
                                       70
<PAGE>   77

condemnation or other governmental taking of any facility or any part thereof,
in excess of $10 million. Under the collateral agency and intercreditor
agreement, we and the guarantors are permitted to repair or rebuild such
facilities, or parts thereof if there are sufficient funds (including insurance
or condemnation proceeds) to do so, and if we provide an officer's certificate
that certifies that no material adverse effect on us, could reasonably be
expected to result. If we or any guarantor repair or rebuild any facility and
the insurance or condemnation proceeds are greater than the cost of such repair
or rebuilding and if such excess amount is greater than $5 million, then only
the remaining insurance or condemnation proceeds over $5 million will be applied
to a mandatory redemption or a repayment of senior secured indebtedness. In the
event of a mandatory redemption, the redemption price for the bonds will be 100%
of the principal amount of the bonds being redeemed plus interest accrued to but
excluding the date of redemption. Upon the occurrence of any event requiring a
redemption of bonds, we will be required to redeem the bonds and repay other
senior secured indebtedness on a pro rata basis in an aggregate amount equal to
the loss proceeds to be applied as described above.

  OPTIONAL REDEMPTION

     Any series of the bonds will be subject to optional redemption, in whole or
in part on a pro rata basis for the series, at any time, at a redemption price
equal to the principal of, the bond, plus accrued and unpaid interest on the
principal of the bond to but excluding the redemption date, plus a make-whole
premium.

     The "make-whole premium" will be an amount equal to the excess, if any, of
(i) the present value of all interest and principal payments scheduled to become
due after the date of the optional redemption by NRG Northeast in respect of the
bonds being redeemed (the present value to be determined on the basis of a
discount rate equal to the sum of (a) a treasury rate and (b) 25 basis points)
over (ii) the outstanding principal amount of the bonds. "Treasury rate" means
the yield to maturity at the time of computation of United States Treasury
securities with a final maturity (as compiled and published in the most recent
Federal Reserve Statistical Release H.15(519) which has become publicly
available at least two Business Days in New York prior to the redemption date
(or, if such Statistical Release is no longer published, any publicly available
source or similar market data)) most nearly equal to the remaining average life
on the redemption date of the bonds being redeemed, provided, however, that if
the period from the redemption date to the maturity date of the series of bonds
being redeemed is less than one year, the weekly average yield on actually
traded United States Treasury securities adjusted to a constant maturity of one
year will be used.

  SELECTION AND NOTICE

     If less than all of the bonds are to be redeemed at any time, selection of
bonds for redemption will be made by the trustee on a pro rata basis. Notices of
redemption will be mailed by first class mail at least 30 days but not more than
60 days before the redemption date (unless a shorter period will be satisfactory
to the trustee) to each holder of the bonds at its registered address. If any
bond is to be redeemed in part only, the notice of redemption that relates to
that bond will state the portion of the principal amount of the bond to be
redeemed. A new bond in principal amount equal to the unredeemed portion of the
bond will be issued in the name of the holder of the bond upon cancellation of
the original bond. Bonds called for redemption become due on the date fixed for
redemption. On and after the redemption date, interest ceases to accrue on bonds
or portions of them called for redemption.

CHANGE OF CONTROL

     Upon the occurrence of certain events involving a change of control, NRG
Northeast will be required to offer to repurchase all or any part of the
outstanding bonds at a cash price equal to 101% of the then outstanding
principal amount of the bonds, plus accrued and unpaid interest to but excluding
the date of payment. NRG Northeast must send a notice to holders of the bonds
within 30 days of a change of control and must repurchase any bonds validly
tendered pursuant to the offer within 30 to 60 days from the mailing of the
notice.

                                       71
<PAGE>   78

     A change of control means (a) the acquisition of ownership, directly or
indirectly, beneficially or of record or otherwise, by any person or group
(within the meaning of the Exchange Act and the rules of the SEC thereunder as
in effect on the date hereof) other than NRG Energy or wholly-owned
subsidiaries, of ownership interests representing more than 50% of the aggregate
ordinary voting power represented by our membership interests; or (b) the
acquisition of direct or indirect control of us by any person or group other
than NRG Energy or its wholly-owned subsidiaries otherwise than as described in
clause (a). However, there will be no change of control if either: (i) we
receive a confirmation of the ratings of the bonds in effect immediately prior
to the occurrence of such events; or (ii) that change of control is approved by
holders of the bonds holding at least 66 2/3% in the aggregate principal amount
of the then-outstanding bonds.

BOOK-ENTRY, DELIVERY AND FORM

     The certificates representing the bonds will be issued in fully registered
form. Except as described below, the bonds will initially be represented by one
or more global bonds in fully registered form without interest coupons. The
global bonds will be deposited with, or on behalf of, The Depository Trust
Company ("DTC") and registered in the name of Cede & Co., as nominee of DTC, or
will remain in the custody of the trustee pursuant to the FAST Balance
Certificate Agreement between DTC and the trustee.

  CERTAIN BOOK-ENTRY PROCEDURES FOR THE GLOBAL BONDS

     The descriptions of the operations and procedures of DTC set forth below
are provided solely as a matter of convenience. These operations and procedures
are solely within the control of the respective settlement systems and are
subject to change by them from time to time. Neither we nor any of the initial
purchasers takes any responsibility for these operations or procedures, and
investors are urged to contact the relevant system or its participants directly
to discuss these matters.

     DTC has advised us that it is (i) a limited-purpose trust company organized
under the laws of the State of New York, (ii) a "banking organization" within
the meaning of the New York Banking Law, (iii) a member of the Federal Reserve
System, (iv) a "clearing corporation" within the meaning of the Uniform
Commercial Code, as amended, and (v) a "clearing agency" registered pursuant to
Section 17A of the Exchange Act. DTC was created to hold securities for its
participants and facilitates the clearance and settlement of securities
transactions between participants through electronic book-entry changes to the
accounts of its participants, thereby eliminating the need for physical transfer
and delivery of certificates. DTC's participants include securities brokers and
dealers (including the initial purchasers), banks and trust companies, clearing
corporations and certain other organizations. Indirect access to DTC's system is
also available to indirect participants such as banks, brokers, dealers and
trust companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly. Investors who are not participants
may beneficially own securities held by or on behalf of DTC only through
participants or indirect participants.

     We expect that pursuant to procedures established by DTC:

     - Upon issuance of the global bonds, DTC will credit the respective
       principal amounts of the bonds represented by the global bonds to the
       accounts of persons who have accounts with DTC.Ownership of beneficial
       interest in the global bonds will be limited to persons who have accounts
       with DTC, who are referred to as participants, or persons who hold
       interests through participants.

     - Ownership of the beneficial interests in the bonds will be shown on, and
       the transfer of ownership thereof will be effected only through, records
       maintained by DTC (with respect to the interests of participants) and the
       records of participants and the indirect participants (with respect to
       the interests of persons other than participants).

     The laws of some jurisdictions may require that certain purchasers of
securities take physical delivery of such securities in definitive form.
Accordingly, the ability to transfer interests in the bonds represented by a
global bond to these persons may be limited. In addition, because DTC can act
only on behalf of its participants, who in turn act on behalf of persons who
hold interests through participants, the ability of a

                                       72
<PAGE>   79

person having an interest in bonds represented by a global bond to pledge or
transfer such interest to persons or entities that do not participate in DTC's
system, or to otherwise take actions in respect of such interest, may be
affected by the lack of a physical definitive security in respect of such
interest.

     So long as DTC or its nominee is the registered owner of the global bonds,
DTC or the nominee, as the case may be, will be considered the sole owner or
holder of the bonds represented by the global bonds for all purposes under the
indenture and the bonds. Except as provided below, owners of beneficial
interests in a global bond will not be entitled to have bonds represented by the
global bonds registered in their names, will not receive or be entitled to
receive physical delivery of certificated bonds in definitive form, and will not
be considered the owners or holders of any bonds under the indenture for any
purpose, including with respect to the giving of any direction, instruction or
approval to the trustee thereunder. Accordingly, each holder of the bonds owning
a beneficial interest in the global bonds must rely on the procedures of DTC
and, if such holder of the bonds is not a participant or an indirect
participant, on the procedures of the participant through which such holder of
the bonds owns its interest, to exercise any rights of a holder of the bonds
under the indenture or such global bond. We understand that under existing
industry practice, in the event that we request any action of holders of bonds,
or a holder of the bonds that is an owner of a beneficial interest in a global
bond desires to take any action that DTC, as the holder of such global bond, is
entitled to take, DTC would authorize the participants to take such action and
the participants would authorize holders of the bonds owning through such
participants to take such action or would otherwise act upon the instruction of
such holders of the bonds. Neither we nor the trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of bonds by DTC, or for maintaining, supervising or
reviewing any records of DTC relating to such bonds.

     Payments with respect to the principal of, and premium, if any, if and
interest on, any bonds represented by the global bonds registered in the name of
DTC or its nominee on the applicable record date will be payable by the trustee
to DTC or its nominee in its capacity as the registered holder of the global
bonds. Under the terms of the indenture, we and the trustee may treat the
persons in whose names the bonds, including the global bonds, are registered as
the owners thereof for the purpose of receiving payment thereon and for any and
all other purposes whatsoever. Accordingly, neither we nor the trustee has or
will have any responsibility or liability for the payment of such amounts to
owners of beneficial interests in a global bond (including principal, premium,
if any, and interest). Payments by the participants and the indirect
participants to the owners of beneficial interests in a global bond will be
governed by standing instructions and customary industry practice and will be
the responsibility of the participants or the indirect participants and DTC.

     Transfers between participants in DTC will be effected in accordance with
DTC's procedures, and will be settled in same-day funds.

  CERTIFICATED BONDS

     If (i) we notify the trustee in writing that DTC is no longer willing or
able to act as a depositary or DTC ceases to be registered as a clearing agency
under the Exchange Act and a successor depositary is not appointed within 90
days of such notice or cessation, (ii) we, at our option, notify the trustee in
writing that we elect to cause the issuance of bonds in definitive form under
the indenture or (iii) upon the occurrence of certain other events as provided
in the indenture, then, upon surrender by DTC of the global bonds, certificated
bonds will be issued to each person that DTC identifies as the beneficial owner
of the bonds represented by the global bonds. Upon any such issuance, the
trustee is required to register the certificated bonds in the name of the person
or persons (or the nominee of any thereof) and cause the same to be delivered
thereto.

     Neither we nor the trustee will be liable for any delay by DTC or any
participant or indirect participant in identifying the beneficial owners of the
related bonds and each such person may conclusively rely on, and will be
protected in relying on, instructions from DTC for all purposes (including with
respect to the registration and delivery, and the respective principal amounts,
of the bonds to be issued).

                  DESCRIPTION OF PRINCIPAL FINANCING DOCUMENTS

     The following summaries of certain provisions of the financing documents do
not purport to be complete and are subject to, and are qualified in their
entirety by reference to, all of the provisions thereof, including definitions
therein of certain terms. Copies of the financing documents have been filed as
exhibits to the registration statement of which this prospectus forms a part.
See "Where You Can Find More Information." Capitalized terms used herein and not
otherwise defined in this prospectus have the meanings ascribed to such terms in
the respective financing documents. For purposes of this section, references to
the "NRG Northeast", "us", "we" and "our" do not include the guarantors.

LOAN FACILITIES

     On June 4, 1999, we executed a loan agreement under which the lenders party
thereto agreed to loan, with the guarantee of certain of our guarantors, (i) an
aggregate principal amount of up to $646,564,000 under a term loan facility to
finance the acquisition of certain of our facilities, and (ii) $40,000,000 for
our working capital needs under our old working capital facility. As of December
31, 1999, the term loan facility had been fully drawn. All amounts outstanding
under the term loan facility were repaid in full with the proceeds of the sale
of the outstanding bonds. Contemporaneously with the closing of the issuance of
the outstanding bonds on February 22, 2000, we entered into a new working
capital facility. At that time, the loan agreement was terminated.

NEW WORKING CAPITAL FACILITY

     On the date of the issuance of the outstanding bonds we entered into a
364-day $50 million floating rate working capital revolving facility provided by
a syndicate of financial institutions led by Citibank, N.A. and The Chase
Manhattan Bank. The proceeds of this facility will be used to finance the
ordinary course working capital needs (other than debt service) of us and the
guarantors. The lenders under this facility were granted a security interest in
the same collateral that secures the bonds (other than the debt service reserve
account which is maintained by the trustee solely for the benefit of the holders
of the bonds and the bonds issued under the indenture in the future) and ranks
equally with the holders of the bonds and the guarantors guaranteed repayment of
this facility. The covenants and events of default in the working capital
facility are substantially similar to those set forth in the indenture.

INDENTURE

     The bonds will be issued pursuant to an indenture, as supplemented by the
first supplemental indenture, by and among NRG Northeast, the guarantors and The
Chase Manhattan Bank, as trustee. The terms of the bonds include those stated in
the indenture and those made part of the indenture by reference to the Trust
Indenture Act. The bonds are senior secured obligations and rank senior in right
of payment to all of our existing and future indebtedness that is designated as
subordinate or junior in right of payment to the bonds.

     COVENANTS OF NRG NORTHEAST

     Following is a description of certain covenants with which we are obligated
to comply under the indenture so long as any bonds remain outstanding.

     Information Requirements

     We will furnish or cause to be furnished to the trustee and the rating
agencies:


     - within 105 days after the end of each fiscal year of NRG Northeast, (i)
       the audited consolidated balance sheet and related statements of
       operations, members' equity and cash flows of NRG Northeast and our
       subsidiaries as of the end of and for such year, and (ii) the audited
       consolidated balance sheet and related statements of operations, members'
       equity and cash flows of NRG Northeast and the guarantors (excluding the
       financial condition and results of operation of the unrestricted
       subsidiaries) as of the end of and for such year setting forth in each
       case in comparative form the figures for the


                                       74
<PAGE>   81

       previous fiscal year, all reported on by PricewaterhouseCoopers LLP or
       other independent public accountants of recognized national standing
       (without a "going concern" or like qualification or exception and without
       any qualification or exception as to the scope of such audit) to the
       effect that such consolidated financial statements present fairly in all
       material respects our financial condition and results of operations and
       the financial condition and results of operations of our subsidiaries on
       a consolidated basis in accordance with GAAP consistently applied;

     - within 60 days after the end of each of the first three quarters of each
       fiscal year, (i) the unaudited consolidated balance sheet and related
       statements of operations, members' equity and cash flows of NRG Northeast
       and our subsidiaries as of the end of and for such fiscal quarter and the
       then elapsed portion of the fiscal year and (ii) the unaudited
       consolidated balance sheet and related statements of operation, members'
       equity and cash flows of NRG Northeast and the guarantors (excluding the
       financial condition and results of operations of the unrestricted
       subsidiaries), setting forth in each case in comparative form the figures
       for (or, in the case of the balance sheet, as of the end of) the
       corresponding period or periods of the previous fiscal year, all
       certified by an authorized representative of ours as presenting fairly in
       all material respects our financial condition and results of operations
       and the financial condition and results of operations of our subsidiaries
       on a consolidated basis in accordance with GAAP consistently applied,
       subject to normal year-end audit adjustments and the absence of
       footnotes;

     - concurrently with any delivery of financial statements under the
       immediately preceding two "bullet points", an officer's certificate (i)
       certifying as to whether, to the best knowledge of the signer thereof,
       certain defaults have occurred and, if such a default has occurred,
       specifying the details thereof and any action taken or proposed to be
       taken with respect thereto, (ii) stating whether any change in GAAP or in
       the application thereof has occurred since the date of the most recent
       prior audited financial statements delivered pursuant to the first
       "bullet point" above or delivered to holders of the bonds on or prior to
       the date of the issuance of the outstanding bonds, as applicable, and, if
       any such change has occurred, specifying the effect of such change on the
       financial statements accompanying such certificate;

     - concurrently with any delivery of financial statements under the first
       "bullet-point" above, a certificate of the accounting firm that reported
       on such financial statements stating whether they obtained knowledge
       during the course of their examination of such financial statements of
       defaults involving the making of restricted payments;

     - promptly after the same become publicly available, copies of all periodic
       and other reports, proxy statements and other materials filed by us or
       any of the guarantors with the SEC, or any governmental authority
       succeeding to any or all of the functions of said commission, or with any
       national securities exchange, or distributed by us to our members
       generally, as the case may be;

     - promptly after receiving notice of the same, copies of any information
       with respect to any material litigation or material governmental or
       environmental proceedings against us or the guarantors; and

     - promptly following any request, such other information regarding our
       operations, business affairs and financial condition or the operations,
       business affairs and financial condition of us or any of the guarantors,
       or compliance with the terms of the indenture and the other transaction
       documents, as the trustee or majority holders of the bonds may reasonably
       request.

     Maintenance of Existence

     We will, and will cause each of the guarantors to, do or cause to be done
(i) all things necessary to preserve, renew and keep in full force and effect
our legal existence as a limited liability company, provided that we may change
our status as a limited liability company if each of the rating agencies
confirms its then current rating of the bonds and we otherwise comply with the
financing documents and (ii) all things reasonably necessary to preserve, renew
and keep in full force and effect the rights, licenses, permits, privileges and
franchises material to the conduct of our business as then conducted. The
foregoing will neither prohibit

                                       75
<PAGE>   82

any merger, consolidation, liquidation or dissolution permitted under the
indenture, nor prohibit NRG Northeast or any guarantor from changing its status
as a limited liability company if the rating agencies confirm their current
ratings of the bonds and NRG Northeast or such guarantor otherwise complies with
all obligations under the financing documents.

     Maintenance of Tax Status

     We will not, and will cause each of the guarantors not to, voluntarily take
any action to cause us or any guarantors to be subject to taxation as a separate
entity for federal income tax purposes.

     Compliance with Laws and Contractual Obligations

     We will, and will cause each of our subsidiaries to, comply with all laws,
rules, regulations and orders of any governmental authority (including
environmental laws and ERISA matters), and all contractual obligations
applicable to us or our property, except where the failure to do so,
individually or in the aggregate, could not reasonably be expected to result in
a material adverse effect on us and the guarantors taken as a whole.

     Maintenance of Property

     We will, and will cause each of the guarantors to, keep and maintain all
property material to the conduct of our business in good working order and
condition, ordinary wear and tear excepted. Neither we nor any guarantor will be
prevented from disposing of any asset (subject to certain prohibitions on
selling assets and on making fundamental changes described under "Limitation on
Fundamental Changes" and "Limitation on Sale of Assets" below) or from
discontinuing the operation or maintenance of any of such material properties if
such discontinuance is, as determined by us in good faith, desirable in the
conduct of our business or the business of any guarantor and would not
reasonably be expected to have a material adverse effect on us and the
guarantors taken as a whole.

     Insurance

     We will, and will cause each of the guarantors to, maintain, with
financially sound and reputable insurance companies, insurance with respect to
each facility in such amounts and against such risks as are customarily
maintained by companies engaged in the same or similar businesses operating in
the same or similar locations. We will maintain and will cause each of the
guarantors to maintain insurance for risks customarily insured against by other
enterprises with similar capital structures and owning and operating facilities
of like size and type as that of the facilities in accordance with prudent
industry practice.

     Flow of Funds

     We will provide funds to each of the guarantors at such times and in such
amounts so as to enable each of the guarantors to pay all operating expenses
incurred by each such guarantor on or before the date such operating expenses
become due and payable. If, on the last business day of each calendar month, the
funds available to us exceed the amount equal to the aggregate amount of our
operating expenses and the operating expenses of the guarantors then due and
payable plus our operating expenses and those of the guarantors reasonably
anticipated to become due and payable during the following calendar month, then,
on or before the third business day of such following calendar month, we will
deposit into the debt service reserve account an amount equal to the lesser of
(i) the debt service reserve shortfall, if any, determined as at the last
business day of a calendar month and (ii) the amount of such excess.

     Creation of the Debt Service Reserve Account

     We established at the trustee's corporate trust office a special,
irrevocable collateral account called the debt service reserve account which
will be maintained at all times until the termination of the indenture. All
amounts from time to time held in this account will be held (i) in the name of
the trustee for the benefit of the holders and (ii) under the exclusive dominion
and control of the trustee. Except as expressly provided in the
                                       76
<PAGE>   83

indenture, neither we nor any guarantor will have any right to withdraw funds
from this account. All amounts on deposit in the debt service reserve account
and all investments held therein will constitute a part of the collateral and
will not constitute payment of any bond until applied as provided in the
indenture. We irrevocably authorized the trustee to withdraw funds from the debt
service reserve account in accordance with the indenture.

     The debt service reserve account must contain a sufficient amount at all
times to pay the principal and interest on all series of bonds due on the next
scheduled payment date for each series of bonds. We do not have to fund this
account with cash if we obtain an acceptable debt service reserve support
instrument which may be either a guarantee by an acceptable bank, NRG Energy or
its affiliate other than NRG Northeast (so long as NRG Energy or such affiliate
maintains a long-term senior unsecured debt rating of "Baa3" or better by
Moody's and "BBB-" or better by S&P) or a letter of credit provided by a
commercial bank or other financial institution with a long-term senior unsecured
debt rating of "A2" or better by Moody's and "A" or better by S&P.

     We may direct withdrawal from the debt service reserve account (i) to the
extent that no other funds are available to pay principal or interest on the
bonds of any series that are due on the date of such withdrawal and (ii) if on
any scheduled payment date the trustee will have received from us funds that are
insufficient to pay the aggregate amount of the principal and interest then due.

     If on any scheduled payment date the trustee will have received funds that
are insufficient to pay the aggregate amount of such principal and interest in
full, then, the trustee will transfer from the debt service reserve account, to
the extent funds are available therein, to the accounts of the holders an amount
equal to such insufficiency.

     If on any date on which the trustee is required to make withdrawals from
the debt service reserve account, the funds on deposit are insufficient to make
such withdrawals, the trustee will draw on a demand payment under any debt
service reserve support instrument then in its possession in an amount equal,
when added to all amounts paid under each other debt service reserve support
instrument on such date, to such insufficiency.

     Limitation on Incurrence of Indebtedness

     We will not (i) create, incur, assume or permit to exist any indebtedness,
except permitted indebtedness; (ii) permit any guarantor to create, incur,
assume or permit to exist any indebtedness, except its guarantee of the bonds or
its guarantee of other permitted indebtedness (other than subordinated
indebtedness), and intercompany loans; or (iii) permit any unrestricted
subsidiary to create, incur, assume or permit to exist any indebtedness, except
for non-recourse obligations.

     "permitted indebtedness" will be any of the following items of
indebtedness:

     - the outstanding bonds and the bonds;

     - other indebtedness, provided, that after giving effect to the incurrence
       of such indebtedness on a pro forma basis and the application of the net
       proceeds thereof (A) there is no current default or event of default
       unless the proceeds of such indebtedness are applied to cure, and such
       application does cure, such default or event of default; and (B) we
       provide an officer's certificate that certifies that (x) the minimum
       annual projected debt service coverage ratio for each calendar year
       commencing with the year in which such indebtedness is incurred through
       the final maturity of the bonds is no less than 2.00 to 1; and (y) the
       debt service coverage ratio for our preceding four consecutive fiscal
       quarters (taken as a whole) was not less than 2.00 to 1 (or such shorter
       period covering the quarters ended subsequent to the issuance of the
       bonds); and (C) each of the rating agencies confirms its then current
       rating on the bonds;

     - indebtedness for working capital purposes not to exceed in the aggregate
       the sum of $50,000,000, plus, upon the acquisition of any subsequent
       guarantor or any additional facility by a guarantor or NRG Northeast, 4%
       of the indebtedness incurred by us in connection with such acquisition;

                                       77
<PAGE>   84

     - indebtedness related to permitted liens (as described under "Limitation
       on Liens" below);

     - indebtedness to any of the guarantors;

     - indebtedness represented by hedging agreements permitted by the indenture
       which are not for speculative purposes;

     - indebtedness in the form of performance or payment guarantees entered
       into by us in the ordinary course of business in connection with (i) fuel
       procurement by NRG Power Marketing directly related to the facilities,
       (ii) sales or purchases of emissions credits by NRG Power Marketing
       directly related to the facilities and (iii) sales of electrical
       generating energy, capacity and ancillary services by NRG Power Marketing
       directly related to the facilities, in each case, so long as such
       activities are not for speculative purposes;

     - indebtedness in respect of letters of credit, surety bonds or performance
       bonds issued in the ordinary course of business;

     - trade accounts payable or other similar indebtedness arising, and accrued
       expenses incurred, in the ordinary course of business (but not in any
       case for borrowed money);

     - other senior indebtedness not to exceed $15,000,000; and

     - subordinated indebtedness.

     "debt service coverage ratio" will mean for any period, on a consolidated
basis of NRG Northeast and the guarantors, without the inclusion of unrestricted
subsidiaries and without duplication, the ratio of (x) all revenues minus all
operating, maintenance, general and administrative expenses (other than
nonrecurring expenses in connection with the issuance of permitted
indebtedness), minus all capital expenditures (unless funded with permitted
indebtedness) to (y) the aggregate of principal, interest and fees payable on
the bonds and all other permitted indebtedness (other than subordinated
indebtedness, fees in connection with the issuance of permitted indebtedness and
principal payments under the working capital facility, provided that such
amounts remain available to be drawn under the working capital facility or are
refinanced under a replacement working capital facility) plus net payments under
any interest rate agreements less payments to be received under any letter of
credit for such period.

     "intercompany loan" will mean loans to NRG Northeast or any guarantor by
NRG Northeast or any guarantor.

     "non-recourse obligations" will mean indebtedness or other obligations or
liabilities (i) as to which neither we nor any of the guarantors (a) provides
credit support of any kind (including any undertaking, agreement or instrument
that would constitute indebtedness), (b) is directly or indirectly liable (as a
guarantor or otherwise) other than pursuant to a pledge by NRG Northeast of an
equity interest in the obligor of the indebtedness or (c) constitutes the lender
and (ii) no default with respect to which (including any rights any person may
have to take enforcement action against an unrestricted subsidiary) would permit
(upon notice, lapse of time or both) any holder of the bonds or any of our
indebtedness or any indebtedness of any guarantor to declare a default on such
indebtedness or cause the payment thereof to be accelerated or payable prior to
its stated maturity.

     Limitation on Restricted Payments

     We will not make, or agree to pay or make, directly or indirectly, any
restricted payment, unless, at the time of and after giving effect to such
restricted payment (i) no default or event of default will have occurred and be
continuing or would occur as a consequence of such restricted payment; (ii) the
debt service reserve account is funded up to the debt service reserve
requirement; (iii) the debt service coverage ratio for the preceding four
consecutive quarters (or such shorter period covering the quarters ended
subsequent to the issuance of the bonds, taken as a consecutive period) was not
less than 1.50 to 1.0 in the case of any such period ending prior to December
31, 2003 or 1.70 to 1.0 for any such period ending thereafter; (iv) the
projected debt service coverage ratio for the next succeeding eight calendar
quarters (taken as two periods of

                                       78
<PAGE>   85

four quarters and determined as of the beginning of the quarter during which the
determination is made) is not less than 1.50 to 1.0 in the case of any such four
quarter period ending prior to December 31, 2003 or 1.70 to 1.0 for any such
four quarter period ending thereafter; and (v) we certify that making the
restricted payment would not reasonably be expected to have a material adverse
effect on us and the guarantors taken as a whole. Restricted payments by any
guarantor that is not a wholly-owned subsidiary of ours made otherwise than to
us will be subject to the restrictions set forth in clauses (i), (ii), (iii),
(iv) and (v) of the preceding sentence. Restricted payments to us by any of our
wholly-owned subsidiaries will not be subject to conditions.

     "restricted payments" are (i) membership distributions by or distributions
in respect of any equity interest in us or any guarantor (in cash, property,
securities or obligations) on, or (ii) any other payments or distributions on
account of payments of interest, or the setting apart of money for a sinking or
other analogous fund for, or the purchase, redemption, retirement or other
acquisition of, (a) subordinated indebtedness or (b) any portion of any
membership interest or equity interest in us or such guarantor or of any
warrants, options or other rights to acquire any such membership interest or
equity interest (or to make any payments to any person, such as "phantom stock"
payments, where the amount thereof is calculated with reference to fair market
or equity value of NRG Northeast or any guarantors). However, distributions or
other payments by one of the guarantors to us will not constitute restricted
payments.

     Notwithstanding the foregoing, we will not be restricted from making (i)
payments to NRG Energy of any proceeds from treasury locks entered into by us on
or prior to the date of the issuance of the outstanding bonds or (ii) the
repayment on that date of loans made by NRG Energy in connection with the
acquisition of the Connecticut facilities and assumed by us.

     Limitation on Liens

     We will not, nor will we permit any of the guarantors to, create, incur,
assume or permit to exist any lien on any property or asset now owned or
hereafter acquired, or assign or sell any income or revenues (including accounts
receivable) or rights in respect of any thereof, other than permitted liens.

     "permitted liens" will be any of the following liens:

     - liens in favor of us or any guarantor;

     - liens imposed by law for taxes, assessments or governmental charges that
       are not yet delinquent and remain payable without penalty or that are
       being contested in compliance in good faith by appropriate proceeding;

     - carriers', warehousemen's, mechanics', materialmen's, repairmen's and
       other like liens imposed by law, arising in the ordinary course of
       business and securing obligations that are not overdue by more than 45
       days or are being contested in good faith by appropriate proceedings;

     - pledges and deposits made in the ordinary course of business in
       compliance with workers' compensation, unemployment insurance and other
       social security laws or regulations or other statutory obligations of NRG
       Northeast or any guarantor;

     - cash deposits or rights of set-off to secure the performance of bids,
       lenders, trade contracts, leases, statutory obligations, surety and
       appeal bonds, performance bonds, government contracts and other
       obligations of a like nature (other than for payment obligations of
       borrowed money), in each case in the ordinary course of business;

     - judgment liens in respect of judgments that do not give rise to an event
       of default under the indenture;

     - certain encumbrances and other easements, zoning restrictions,
       rights-of-way and similar charges or encumbrances on real property
       imposed by law or arising in the ordinary course of business that do not
       secure any monetary obligations and do not materially detract from the
       value of the affected property or interfere with our ordinary conduct of
       business or the ordinary conduct of business of any of the guarantors;

                                       79
<PAGE>   86

     - liens securing hedging agreements which hedging agreements relate to
       indebtedness that is secured by liens otherwise permitted under the
       indenture;

     - liens that are incidental to our business or the business of the
       guarantors, are not for borrowing money and are not material, taken as a
       whole to our business and the business of the guarantors;

     - liens created or granted pursuant to the security documents; and

     - liens with respect to other permitted indebtedness (other than
       subordinated indebtedness), so long as the bonds are secured on an equal
       and ratable basis with the obligation so secured until such obligation is
       no longer secured.

     Certain Obligations Respecting Subsidiaries.

     In the event that we form or acquire any new subsidiary that constitutes a
subsidiary under the indenture, we must designate such new subsidiary as a
"guarantor" or an "unrestricted subsidiary" and we will or will cause each new
subsidiary designated as a guarantor:

     - to become an "obligor" under the security agreement;

     - to take such action (including delivering such membership interests or
       other ownership interests, executing and delivering such Uniform
       Commercial Code financing statements) as will be necessary to create and
       perfect valid and enforceable first priority liens on substantially all
       of the personal property of such guarantor on which a lien is required to
       be created pursuant to the security agreement as collateral security for
       the obligations of such guarantor under the indenture; and

     - to take such action, from time to time as will be necessary to ensure
       that any such guarantor remain at all times a "guarantor" under the
       indenture except as otherwise permitted under the indenture.

     An "unrestricted subsidiary" is (i) any of our subsidiaries that is
designated by our board of directors as an unrestricted subsidiary pursuant to a
board resolution; but only to the extent that such subsidiary: (a) has no
indebtedness or other liabilities or obligations other than non-recourse
obligations; (b) is not party to any agreement, contract, arrangement or
understanding with us or any of our guarantors unless the terms of any such
agreement, contract, arrangement or understanding are no less favorable to us or
such guarantor than those that might be obtained at the time from persons who
are not our affiliates; and (c) is a person with respect to which neither we nor
any of the guarantors has any direct or indirect obligation (x) to subscribe for
additional equity interests or (y) to maintain or preserve such person's
financial condition or to cause such person to achieve any specified levels of
operating results.

     If, at any time, any unrestricted subsidiary would fail to meet the
foregoing requirements as an unrestricted subsidiary, it will thereafter cease
to be an unrestricted subsidiary and such subsidiary will be deemed to be a
guarantor and any indebtedness of such subsidiary will be deemed to be incurred
by a guarantor as of such date (and, if such indebtedness is not permitted to be
incurred as of such date the indenture, we will be in default). Our board of
directors may at any time designate any unrestricted subsidiary to be a
guarantor. Such a designation will be an incurrence of indebtedness by a
guarantor of any outstanding indebtedness of such unrestricted subsidiary and
such designation will only be permitted if (i) such indebtedness is permitted
under the indenture, and (ii) no default or event of default would occur or be
in existence following such designation.

     We will, and will cause each of our subsidiaries to, take such action from
time to time as will be necessary to ensure that our ownership in the voting
equity interests of each of the guarantors will at all times exceed 50% of all
such voting equity interests. In the event that any additional membership
interests are issued by any subsidiary of ours (other than an unrestricted
subsidiary), we agree to deliver to the collateral agent pursuant to the
security agreement the certificates evidencing such equity interests,
accompanied by undated stock powers executed in blank and to take such other
action as the trustee will request to perfect the security interest created
therein pursuant to the security agreement.

     Limitation on Fundamental Changes

     Except as permitted under the provision described "Limitation on Asset
Sales", we will not, nor will we permit any of the guarantors to, merge into or
consolidate with any other person or permit any other person to merge into or
consolidate with us, or sell, transfer, lease or otherwise dispose of all or any
substantial part of our assets, or all or substantially all of the membership or
other equity interests of any of our subsidiaries, or liquidate or dissolve,
except that, if, as a result thereof no default will have occurred and be
continuing:

     - any subsidiary may merge into us in a transaction in which we are the
       surviving corporation;

     - any guarantor may merge into any guarantor in a transaction in which the
       surviving entity is a guarantor and our economic interest in each merging
       guarantor's assets will not have been diminished as a result of such
       merger;

     - any guarantor may sell, transfer, lease or otherwise dispose of its
       assets to us or to another guarantor (provided that our economic interest
       in such assets is not diminished as a result thereof); and

     - any guarantor may liquidate or dissolve if the assets of that guarantor
       are transferred to another guarantor (provided that our economic interest
       in such assets is not diminished as a result thereof) and if we determine
       in good faith that such liquidation or dissolution is in our best
       interests and is not materially disadvantageous to the holders of the
       bonds.

     Limitation on Sale of Assets

     We will not, and will not permit the guarantors to, sell or otherwise
dispose of any assets other than:

     - transfers of assets among us and the guarantors;

     - sales and dispositions in the ordinary course of business not in excess
       of $20,000,000 in aggregate for us and the guarantors in any fiscal year;

     - any sales or dispositions of surplus, obsolete or worn-out equipment;

     - any sales or dispositions required for compliance with applicable law or
       necessary governmental approvals;

     - sales or dispositions of non-controlling ownership interests in
       guarantors in accordance with the indenture so long as the guarantee with
       regard to such guarantor stays in effect;

     - sales or dispositions of ownership interests in unrestricted
       subsidiaries;

     - any sales or dispositions of assets permitted under the indenture as a
       permitted fundamental change (see "Limitation on Fundamental Change"
       above); and

     - any other sale or other disposition so long as after giving effect to
       such events, the rating agencies will have confirmed their respective
       ratings of the bonds in effect immediately prior to such sale or other
       disposition.

     Limitation on Business Activities

     We will not, nor will we permit any of the guarantors to, engage to any
material extent in any business other than, (i) in our case, the ownership of
the guarantors and the unrestricted subsidiaries and the ownership and operation
of non-nuclear electric generating facilities and (ii) in the case of the
guarantors (including subsequent guarantors), the ownership and operation of
their respective facilities and the ownership and operation of other non-nuclear
electric generating facilities.

     Limitation on Transactions with Affiliates

     Subject to certain exceptions, we will not, nor will we permit any of our
subsidiaries (other than unrestricted subsidiaries) to, sell, lease or otherwise
transfer any property or assets to, or purchase, lease or

                                       81
<PAGE>   88

otherwise acquire any property or assets from, or otherwise engage in any other
transactions with, any of our affiliates, except:

     - transactions in the ordinary course of business at prices and on terms
       and conditions not less favorable to us or our subsidiary than could be
       obtained on an arm's-length basis from unrelated third parties;

     - transactions between or among us and the guarantors not involving any
       other affiliate;

     - any restricted payment permitted under the indenture; and

     - transactions that are contemplated by any transaction document or any
       extensions, renewals or replacements thereof that will not have a
       material adverse effect on us and the guarantors, taken as a whole.

     Limitation on Investments

     We will not, nor will we permit any guarantor to, make or permit to remain
outstanding any investments except:

     - investments outstanding on the date of the issuance of the outstanding
       bonds;

     - operating deposit accounts with banks;

     - cash or permitted investments;

     - investments by us or the guarantors in us or the guarantors (including
       investments by us in intercompany loans);

     - investments in another person, if as a result of such investment (A) such
       other person becomes a guarantor or (B) such other person is merged or
       consolidated with or into, or transfers or conveys all or substantially
       all of its assets to us or a guarantor;

     - investments representing capital stock or obligations issued to, us or
       any guarantor in settlement of claims against any other person by reason
       of a composition or readjustment of debt or a reorganization of any
       debtor of ours or any guarantor;

     - investments in the bonds;

     - investments acquired by NRG Northeast or any of the guarantors in
       connection with any asset sale permitted under the indenture to the
       extent such investments are non-cash proceeds;

     - any investment to the extent that the consideration therefor is capital
       stock (other than redeemable capital stock) of NRG Northeast;

     - investments consisting of security deposits with utilities and other
       persons made in the ordinary course of business;

     - hedging agreements entered into in the ordinary course of business and
       not for speculative purposes;

     - amounts which we or the guarantors would otherwise be permitted to make
       under the indenture if such amount were a restricted payment; and

     - additional investments up to but not exceeding $10,000,000 in the
       aggregate.

     For purposes of the immediately preceding "bullet-point" above, the
aggregate amount of an investment at any time will be deemed to be equal to (A)
the aggregate amount of cash, together with the aggregate fair market value of
property, including any securities, loaned, advanced, contributed, transferred
or otherwise invested that gives rise to such investment minus (B) the aggregate
amount of dividends, distributions or other payments received in cash in respect
of such investment; the amount of an investment will not in any event be reduced
by reason of any write-off of such investment nor increased by any increase in
the amount of earnings retained in the person in which such investment is made
that have not been dividend, distributed or otherwise paid out.

     Limitation on Restrictive Agreements

     We will not, and will not permit any of the guarantors to, directly or
indirectly, enter into, incur or permit to exist any agreement or other
arrangement that prohibits, restricts or imposes any condition upon (a) our
ability or the ability of any guarantor to create, incur or permit to exist any
lien upon any of our or its property or assets that is either (i) created under
the transaction documents or (ii) in our favor, or (b) the ability of any
guarantor to pay dividends or other distributions with respect to any shares of
its capital stock or to make or repay loans or advances to us or any other
guarantor or to guarantee our indebtedness or any the indebtedness of any other
guarantor except such prohibition, restriction or condition existing under or by
reason of: (1) applicable law, (2) the indenture or any financing document, (3)
with respect to real property, customary non-assignment provisions of any
contract or any lease governing a leasehold interest of any guarantor, (4) any

agree or consent to, nor allow any of the guarantors to agree or consent to, any
termination, modification, supplement, replacement or waiver of any transaction
document unless such termination, modification, supplement, replacement or
waiver could not, individually or collectively with all other such terminations,
modifications, supplements, replacements and waivers, reasonably be expected to
have a material adverse effect on us and the guarantors, taken as a whole.

                                       83
<PAGE>   90

     Other Covenants

     The indenture also contains certain other covenants, including our
obligations to, and to cause each of the guarantors to: (i) pay all taxes and
claims; (ii) maintain books and records; and (iii) maintain the EWG status of
each of the guarantors.

  GUARANTOR COVENANTS

     Following is a description of certain covenants made by each of the
guarantors in favor of the trustee and the holders of the bonds with which the
guarantors will be obligated to comply under the indenture so long as the bonds
remain outstanding.

     Existence; Conduct of Business

     Each guarantor will do or cause to be done all things necessary to
preserve, renew and keep in full force and effect such guarantor's legal
existence as a limited liability company and all things reasonably necessary to
preserve, renew and keep in full force and effect such guarantor's rights,
licenses, permits, privileges and franchises material to the conduct of such
guarantor's business as then conducted. The foregoing will neither prohibit any
merger, consolidation, liquidation or dissolution permitted under the indenture,
nor prohibit any guarantor from changing its status as a limited liability
company if the rating agencies confirm their current ratings of the bonds and
such guarantor otherwise complies with all obligations under the financing
documents.

     Compliance with Laws and Contractual Obligations

     Each guarantor will comply with all laws (including environmental laws and
ERISA matters) and all contractual obligations, in each case, as applicable to
such guarantor or its property, except where the failure to do so, individually
or in the aggregate, would not reasonably be expected to result in a material
adverse effect on us and the guarantors, taken as a whole.

     Maintenance of Properties

     Each guarantor will keep and maintain all property material to the conduct
of such guarantor's business in good working order and condition, ordinary wear
and tear excepted. The guarantor will not be prevented from disposing of any
asset (subject to compliance with the indenture) or from discontinuing the
operation or maintenance of any of such material properties if the guarantor
reasonably determines in good faith that such discontinuance is desirable in the
conduct of its business and would not reasonably be expected to have a material
adverse effect.

     Insurance

     Each guarantor will maintain, with financially sound and reputable
insurance companies, insurance with respect to each facility in such amounts and
against such risks as are customarily maintained by companies engaged in the
same or similar businesses operating in the same or similar locations in
accordance with prudent industry practices. Each guarantor agrees that it will
maintain insurance for risks customarily insured against by other enterprises
with similar capital structures and owning and operating facilities of like size
and type as that of the facilities in accordance with prudent industry practice.

     Limitation on Indebtedness

     Each guarantor will not create, incur, assume or permit to exist any
indebtedness, except intercompany loans, the guarantees of the bonds or
guarantees of other permitted indebtedness (other than subordinated
indebtedness).

                                       84
<PAGE>   91

     Limitation on Liens

     Each guarantor will not create, incur, assume or permit to exist any lien
on any property or asset now owned or hereafter acquired by such guarantor, or
assign or sell any income or revenues (including accounts receivable) or rights
in respect of any thereof, except permitted liens.

     Prohibition on Fundamental Changes

     Except for the asset sales otherwise permitted by the indenture, each
guarantor will not merge into or consolidate with any other person, or permit
any other person to merge into or consolidate with such guarantor, or sell,
transfer, lease or otherwise dispose of all or any substantial part of its
assets, or liquidate or dissolve, except that (i) each guarantor may merge into
a subsidiary in a transaction in which such guarantor is the surviving
corporation, (ii) any guarantor may merge into any other guarantor in a
transaction in which the surviving entity is a guarantor, (iii) each guarantor
may sell, transfer, lease or otherwise dispose of such guarantor's assets to us
or a guarantor and (iv) any guarantor may liquidate or dissolve if we determine
in good faith that such liquidation or dissolution is in the best interests of
the guarantor and is not materially disadvantageous to the holders of the bonds,
provided that no default will have occurred and be continuing as a result of any
of the events described in clauses (i), (ii) or (iii) above.

     Limitation on Business Activities

     Each guarantor will not engage, to any material extent, in any business
other than the ownership and operation of non-nuclear electric generating
facilities. In the event an entity becomes a guarantor after the date of the
issuance of the outstanding bonds, such guarantor agrees that it will not engage
to any material extent in any business other than the ownership and, operation
of non-nuclear electric generating facilities.

     Limitation on Payments

     Each guarantor will not make, or agree to pay or make, directly or
indirectly, any restricted payment, unless such payment is only (a) to us at any
time or (b) to any future minority owners of the guarantors only if at the time
of such restricted payment we would be permitted to make the payment to such
other minority owner as if such minority owner held a minority interest in us
instead of such guarantor.

     Limitation on Transactions with Affiliates

     Subject to certain exceptions, each guarantor will not sell, lease or
otherwise transfer any property or assets to, or purchase, lease or otherwise
acquire any property or assets from, or otherwise engage in any other
transactions with, any of such guarantor's affiliates, except (a) transactions
in the ordinary course of business at prices and on terms and conditions not
less favorable to the guarantor than could be obtained on an arm's-length basis
from unrelated third parties, (b) transactions between or among such guarantor
and NRG Northeast or other guarantors not involving any other affiliate, (c) any
restricted payment permitted by the indenture and (d) transactions that are
contemplated by any transaction document or any extensions, renewals or
replacements thereof that will not have a material adverse effect on NRG
Northeast and the guarantors, taken as a whole.

     Limitation on Investments

     Each guarantor will not make or permit to remain outstanding any
investments except:

     - investments outstanding on the date of the issuance of the outstanding
       bonds and identified in the indenture;

     - operating deposit accounts with banks;

     - cash or permitted investments;

     - investments by such guarantor in ourselves or other guarantors;

                                       85
<PAGE>   92

     - investments in another person, if as a result of such investment (A) such
       other person becomes a guarantor or (B) such other person is merged or
       consolidated with or into, or transfers or conveys all or substantially
       all of its assets to NRG Northeast or a guarantor;

     - investments representing capital stock or obligations issued to us or any
       guarantor in settlement of claims against any other person by reason of a
       composition or readjustment of debt or a reorganization of any debtor of
       ours or any guarantor;

     - investments in the bonds;

     - investments acquired by any guarantor or in connection with any asset
       sale permitted under the indenture to the extent such investments are
       non-cash proceeds;

     - any investment to the extent that consideration therefor is capital stock
       (other than redeemable capital stock) of NRG Northeast;

     - investments consisting of security deposits with utilities and other like
       persons made in the ordinary course of business;

     - hedging agreements entered into in the ordinary course of business and
       not for speculative purposes;

     - amounts constituting restricted payments which the guarantors would
       otherwise be permitted to make to minority owners under the indenture;
       and

     - additional investments up to but not exceeding $10,000,000 in the
       aggregate with respect to such guarantor, the other guarantors and NRG
       Northeast.

     For purposes of the immediately preceding "bullet point" above, the
aggregate amount of an investment at any time will be deemed to be equal to (A)
the aggregate amount of cash, together with the aggregate fair market value of
property, including any securities, loaned, advanced, contributed, transferred
or otherwise invested that gives rise to such investment minus (B) the aggregate
amount of dividends, distributions or other payments received in cash in respect
of such investment, the amount of an investment will not in any event be reduced
by reason of any write-off of such investment not increased by any increase in
the amount of earnings retained in the person in which such investment is made
that have not been divided, distributed or otherwise paid out.

     Limitation on the Operation of Facilities

     Each guarantor will operate, or cause to be operated, its respective
facility in accordance with prudent industry practices.

     Prohibition on Sale of Assets

     Each guarantor will not to sell or otherwise dispose of any assets other
than

     - transfers of assets between us and another guarantor;

     - sales and dispositions in the ordinary course of business not in excess
       of $20,000,000 in the aggregate for such guarantor, any other guarantor
       and NRG Northeast in any fiscal year;

     - any sales or dispositions of surplus, obsolete or worn-out equipment;

     - any sales or dispositions required for compliance with applicable law or
       necessary governmental approvals;

     - any sales or dispositions of assets permitted under the indenture as a
       permitted fundamental change; and

     - any other sale or other disposition so long as after giving effect to
       such events, the rating agencies will have confirmed their respective
       ratings of the bonds in effect immediately prior to such sale or other
       disposition.

     Limitations on the Modification of Certain Documents

     Without the prior consent of the majority holders of the bonds, the
guarantors will not agree or consent to any termination, modification,
supplement, replacement or waiver of any transaction document unless such
termination, modification, supplement, replacement or waiver could not,
individually or collectively with all other such terminations, modifications,
supplements, replacements and waivers, reasonably be expected to have a material
adverse effect on NRG Northeast and the guarantors, taken as a whole.

     law or otherwise);

          (x) the liens created by the collateral documents will at any time not

     trustee, free and clear of all other liens (other than liens permitted
     under the indenture or under the respective collateral documents), or,
     except for expiration in accordance with its terms, any of the collateral
     documents will for whatever reason be terminated or cease to be in full
     force and effect, or the enforceability thereof will be contested by us, or

          (xi) either (a) the indenture or any other financing document is

     to terminate, within 5 days of such termination, (b) termination by any
     guarantor, within 5 days of such termination, or (c) termination by any
     operator, within 30 days of such termination.

  ENFORCEMENT

     If any event of default occurs and is continuing, the trustee may, and upon
written direction of holders of the bonds holding not less than 33 1/3% (in the
case of any event of default specified in clause (i) under "-- Events of
Default" above) or 50% (in the case of an event of default specified in clauses
(ii), (iii), (vi), (viii), (ix), (x), (xi), (xii) or (xiii) under "-- Events of
Default" above) of the aggregate principal amount of the bonds will, (a)
declare, by written notice, the entire outstanding principal amount of the bonds
and accrued interest thereon to be due and payable immediately. However, in the
case of an event of default arising from certain events of bankruptcy or
insolvency with respect to us or any of the guarantors, all outstanding
principal and accrued interest with respect to the bonds will become due and
payable without further action or notice; and (b) proceed to enforce all
remedies available to the trustee under the indenture and the other documents to
which the trustee is a party, including the collateral agency and intercreditor
agreement, or available under applicable law. Holders of the bonds may not
enforce the indenture or the bonds except as provided in the indenture. Subject
to certain limitations, holders of the bonds holding a majority in principal
amount at maturity of the then outstanding bonds may direct the trustee in its
exercise of any trust or power. The trustee may withhold from holders of the
bonds notice of any continuing default or event of default (except a default or
an event of default relating to the payment of principal or interest) if it
determines that withholding notice is in their interest.

                                       88
<PAGE>   95

     No holder of the bonds will have any right to institute any proceeding for
a remedy under the indenture unless:

     - such holder of the bonds has previously given to the trustee written
       notice of a continuing event of default;

     - the holders of the bonds holding not less than 25% in aggregate principal
       amount of the then outstanding bonds have made written request to the
       trustee to institute such proceeding;

     - the holders of the bonds, have offered to the trustee adequate security
       and indemnity against costs and liabilities associated with such
       proceeding;

     - the trustee has failed to institute such proceeding within 60 days after
       the receipt of such notice; and

     - no direction inconsistent with such written request has been given to the
       trustee during such 60 day period by the holders of the bonds of a
       majority in aggregate principal amount of the outstanding bonds of such
       series.

     The right of any holder of the bonds, which is absolute and unconditional,
to receive payment of the principal of, premium, if any, and interest on its
bonds on or after the due date therein expressed, or to institute suit for the
enforcement of such payment on or after such due date, or the obligation of
ours, which is also absolute and unconditional, to pay the principal of,
premium, if any, and interest on each of such bonds to such holder of the bonds
thereof at the time and place set forth in the bonds, will not be impaired or
affected without the consent of such holder of the bonds.

     Priority of Payments during an Event of Default

     Any money collected by the trustee with respect to a series of bonds
pursuant to the indenture will be applied in the following order, at the date or
dates fixed by the trustee and, in case of the distribution of such money on
account of principal (or premium, if any) or interest, upon presentation of the
bonds of such series and the notation thereon of the payment if only partially
paid and upon surrender thereof if fully paid:

          FIRST: To the payment of all amounts due the trustee as compensation
     (including expenses and indemnities) under the indenture, and the balance.

          SECOND: To the payment of the amounts then due and unpaid upon the
     bonds of that series for principal (and premium, if any) and interest, in
     respect of which or for the benefit of which such money has been collected,
     ratably among bonds within each series and among the series, without
     preference or priority of any kind, according to the amounts due and
     payable on such bonds for principal (and premium, if any) and interest,
     respectively.

     Legal Defeasance and Covenant Defeasance

     Legal and covenant defeasance will be permitted upon terms and conditions
customary for transactions of this nature.

     Satisfaction and Discharge

     We may terminate the indenture by delivering all outstanding bonds to the
trustee for cancellation and by paying all other sums payable under the
indenture.

     Amendment, Supplement and Waiver

     Except as provided in the next two succeeding paragraphs, with the consent
of the holders of at least a majority in aggregate principal amount of the bonds
of all series then outstanding, considered as one class, we may, and the
trustee, will, enter into supplemental indentures for the purpose of changing
provisions of the indenture. However, if there are bonds of more than one series
outstanding and if a proposed supplemental indenture will directly affect the
rights of the holders of one or more, but less than all, of such series, then
the

                                       89
<PAGE>   96

consent of only the holders of not less than a majority in aggregate principal
amount of the outstanding bonds of all series so directly affected, considered
as one class, will be required.

     Without the consent of each holder of the bonds affected, no supplemental
indenture will (with respect to any bonds held by a non-consenting holder of the
bonds):

     - reduce the principal amount of bonds whose holders must consent to a
       supplement or waiver;

     - change the principal of or change the fixed maturity of any bond or alter
       certain provisions with respect to the redemption of the bonds;

     - change the rate of or change the time for payment of interest on any
       bond;

     - waive a default or an event of default in the payment of principal of,
       premium, if any, or interest on the bonds;

     - permit the creation of any lien prior to or, except as permitted by the
       indenture, pari passu with the lien of the collateral documents with
       respect to any collateral or deprive any holder of the security afforded
       by the lien of the collateral documents;

     - waive a redemption payment with respect to any bond; or

     - make any change in the foregoing amendment and waiver provisions.

     Notwithstanding the foregoing, without the consent of the holders, we may
enter into one or more supplemental indentures in form satisfactory to the
trustee or enter into any consent with respect to the collateral documents for
the purposes of:

     - establishing the form and terms of bonds of any series permitted under
       the indenture;

     - evidencing the succession of another entity to us and the assumption by
       any such successor to our covenants in the indenture;

     - evidencing the succession of a new trustee pursuant to the indenture;

     - adding further covenants, restrictions, conditions or provisions as the
       board of directors will consider to be for the protection of the holders,
       and to make the occurrence, or the occurrence and continuance of a
       default in any such additional covenants, restrictions, conditions or
       provisions an event of default permitting the enforcement of all or any
       of the several remedies provided in the indenture;

     - conveying, transferring and assigning to the trustee properties or assets
       to secure the bonds, and to correct or amplify the description of any
       property at any time subject to the indenture or the collateral documents
       or to assure, convey and confirm unto the trustee any property subject or
       required to be subject to the indenture or the collateral documents;

     - modifying, eliminating or adding to the provisions of the indenture to
       such extent as will be necessary to qualify, requalify or continue the
       qualification of the indenture (including any supplemental indenture)
       under the Trust Indenture Act, or under any similar United States federal
       statute hereafter enacted, and to add to the indenture such other
       provisions as may be expressly permitted by the Trust Indenture Act,
       excluding, however, the provisions referred to in Section 316(a)(2) of
       the Trust Indenture Act as in effect at the date as of which this
       instrument was executed or any corresponding provision in any similar
       United States federal statute hereafter enacted;

     - permitting or facilitating the issuance of bonds in uncertificated form;

     - changing or eliminating any provision of the indenture or the collateral
       documents. However, if such change or elimination will adversely affect
       the interests of the holders of the bonds of any series, such change or
       elimination will not become effective with respect to such series;

     - curing any ambiguity, correcting or supplementing any provision in the
       indenture or the collateral documents that may be defective or
       inconsistent with any other provision, or making any other

                                       90
<PAGE>   97

provisions with respect to matters or questions arising under the indenture or
the collateral documents. Such action must not adversely affect the interest of
the holders of any series in any material respect; or

     - providing for the issuance of exchange securities, as contemplated by the
       registration rights agreement, and to make such other changes to the
       indenture or the collateral documents as our board of directors
       determines are necessary or appropriate in connection therewith. Such
       action must not adversely affect the interests of the bondholder of any
       series in any material respect.

     Concerning the Trustee

     Holders of the bonds holding a majority in principal amount of the then
outstanding bonds will have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to the trustee,
subject to certain exceptions. The indenture provides that if an event of
default occurs (which is not cured), the trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the conduct
of his own affairs. Subject to such provisions, the trustee will be under no
obligation to exercise any of its rights or powers under the indenture at the
request of any holder of the bonds, unless such holder of the bonds will have
offered to the trustee security and indemnity satisfactory to it against any
loss, liability or expense.

     Transfer and Exchange

     A holder of the bonds may transfer or bonds in accordance with the
indenture. The registrar and the trustee may require a holder of the bonds,
among other things, to furnish appropriate endorsements and transfer documents
and the registrar may require a holder of the bonds to pay any taxes and fees
required by law or permitted by the indenture.

     The registered holder of the bonds will be treated as the owner of it for
all purposes.

SECURITY AGREEMENTS

     Pursuant to the security agreements, secured parties will have a security
interest in certain collateral, including:

     - our membership or other ownership interests in the guarantors;

     - our rights under all the intercompany notes between NRG Northeast and the
       guarantors entered into on the date of the issuance of the outstanding
       bonds;

     - the balance from time to time in the collateral account;

     - the power sales and agency agreements, the operation and maintenance
       agreements, the corporate services agreements and the transition power
       sales contracts; and

     - the revenues from certain power sales contracts entered into by NRG Power
       Marketing associated with the facilities owned by NRG Northeast or the
       guarantors.

COLLATERAL AGENCY AND INTERCREDITOR AGREEMENT

     Pursuant to the collateral agency and intercreditor agreement, NRG
Northeast, the guarantors, the trustee, the agents under the new working capital
facility, and any trustee or agents under any other senior secured debt document
agree to appoint The Chase Manhattan Bank as the collateral agent.

  AUTHORITY OF COLLATERAL AGENT

     The collateral agent will have the authority to administer the
intercreditor collateral in accordance with the security documents, and upon the
occurrence and continuance of an event where 67% of the combined exposure will
have been declared to be, or will automatically have become, due and payable
under the financing documents, as determined by the collateral agent based upon
written notices provided to the collateral agent by the secured parties (a
"trigger event"), will exercise, upon written instruction of persons
                                       91
<PAGE>   98

that at such time hold at least 33 1/3% of the combined exposure (the "required
creditors"), such rights and remedies with respect to the intercreditor
collateral as are granted to it under the security documents and applicable law.

     "combined exposure" means, as of any date of calculation, the sum
(calculated without duplication) of the following to the extent the same is held
by or represented by a secured party (i) the aggregate principal amount of all
bonds outstanding as of the calculation date, (ii) the aggregate principal
amount of all loans (if any) outstanding as of such calculation date under the
working capital facility, (iii) the aggregate amount of all undrawn financing
commitments as of such calculation date under the working capital facility
which, as of such calculation date, the lenders party to the working capital
agreement have no right to terminate, (iv) the aggregate principal amount of all
other senior secured debt (if any) outstanding as of such calculation date and
(v) the aggregate amount of all undrawn financing commitments under any senior
secured debt documents as of such calculation date which, as of such calculation
date, the creditors party to such other senior secured debt documents have no
right to terminate.

     "intercreditor collateral" means any collateral in which there is a
security interest purported to be granted to a secured party other than the debt
service reserve account.

  ACTIONS BY SECURED PARTIES

     No secured party will have any right to (i) sell, exchange, release or
otherwise deal with any property pledged, assigned or mortgaged to secure the
financing liabilities, (ii) exercise or refrain from exercising any rights to
direct the collateral agent to take any action in respect of the intercreditor
collateral or (iii) take any other action with respect to the intercreditor
collateral (A) independently of the collateral agent or (B) other than to direct
the collateral agent to take action in accordance with the collateral agency and
intercreditor agreement.

  PRIORITY OF PAYMENTS

     Following the occurrence of a trigger event or upon the exercise of
remedies by the secured parties after an event of default, the proceeds of any
collection, sale or other realization of any part of the intercreditor
collateral will be applied by the collateral agent in the following order of
priority:

     - First, to the payment of all reasonable costs and expenses relating to
       the sale of the intercreditor collateral plus costs of the collateral
       agent in enforcing the indemnity payment due to the collateral agent;

     - Second, to the payment of accrued and unpaid interest on the bonds, the
       working capital facility and any other senior secured debt, pro rata;

     - Third, to the payment of principal, make-whole premiums, if any, and
       breakage costs, if any, pro rata;

     - Fourth, to the payment of other secured obligations owed to the trustee,
       the working capital agents and each senior secured debt agent, pro rata;
       and

     - Finally, to the payment of the relevant obligor, or its successor or
       assignees, or as a court of competent jurisdiction may direct, of any
       surplus remaining.

  EVENT OF LOSS

     If an event of loss will occur and the determination is made that the
affected property cannot be rebuilt, repaired or restored or NRG Northeast
elects not to rebuild, repair or restore, and loss proceeds exceed $10 million,
then all of the loss proceeds in excess of $10 million will be distributed pro
rata among the secured parties. If an event of loss occurs and NRG Northeast
rebuilds, repairs or restores the affected property and the loss proceeds exceed
the actual cost of such rebuilding, repair or restoration by more than $5
million, then any excess loss proceeds over $5 million will be distributed pro
rata among the secured parties. The pro rata share of loss proceeds owing to the
trustee for the benefit of the holders of the bonds will be applied to the pro
rata redemption of the bonds in accordance with the indenture.
                                       92
<PAGE>   99

  NOTICE

     Each secured party will give each other secured party and the collateral
agent written notice of the occurrence of an event of default under such secured
party's financing documents of which it has written notice and of the occurrence
of an acceleration of the maturity of such secured party's financing
liabilities.

INDEMNIFICATION AGREEMENT

     Pursuant to an indemnification agreement dated as of December 23, 1999, NRG
Energy gave an indemnification in respect of the Fortistar Litigation to the
lender representatives and the financing parties described in such
indemnification agreement. The indemnification agreement provides that NRG
Energy agrees to absolutely and unconditionally indemnify and hold harmless NRG
Northeast, the guarantors, the lender representatives and each financing party
and each related party of any of the foregoing persons (collectively,
"indemnified parties") from all claims of any nature against any indemnified
party arising out of or relating to the Fortistar Litigation.

     NRG Energy has agreed that the trustee and the holders of the bonds also
constitute indemnified parties as such term is used in the indemnification
agreement.

REGISTRATION RIGHTS AGREEMENT


     As part of the sale of the outstanding bonds and under a registration
rights agreement, dated as of February 15, 2000, NRG Northeast and the
guarantors agreed with the initial purchasers, for the benefit of the holders of
the outstanding bonds, to use their reasonable best efforts to file with the SEC
and cause to become effective, at our cost, a registration statement with
respect to a registered offer to exchange the outstanding bonds for bonds which
are in all material respects substantially identical to the outstanding bonds.
Once the registration statement that this prospectus is part of is declared
effective, we will offer the bonds in return for surrender of the outstanding
bonds. This offer will remain open for no less than 30 days after the date a
notice of the exchange offer is mailed to the holders of the outstanding bonds.
For each outstanding bond surrendered to us under the exchange offer, the holder
of outstanding bonds will receive bonds aggregating an equal principal amount.
Interest on each bond will accrue from the last scheduled payment date on which
interest was paid on the outstanding bond so surrendered or, if no interest has
been paid, since February 22, 2000.


     If:

     - because of any change in law or applicable interpretations by the staff
       of the SEC we are not permitted to exchange the outstanding bonds for the
       bonds, or

     - any outstanding bonds validly tendered pursuant to the registered
       exchange offer are not exchanged for bonds upon consummation of the
       exchange offer, or

     - any initial purchaser so requests with respect to outstanding bonds not
       eligible to be exchanged for bonds in the registered exchange offer and
       held by it following the consummation of the registered exchange offer,
       or

     - any applicable law or interpretations do not permit any holder of the
       outstanding bonds other than the initial purchasers to participate in the
       registered exchange offer, or

     - any holder of the outstanding bonds that participates in the registered
       exchange offer does not receive freely transferable exchange securities
       in exchange for tendered securities, or

     - we so elect,

then we will, at our cost, use our reasonable best efforts (subject to customary
representations and agreements of the holders of the bonds) to have a shelf
registration statement covering resale of the outstanding bonds declared
effective and kept effective until February 22, 2002, subject to specified
exceptions.

                                       93
<PAGE>   100

     We will, in the event of such a shelf registration, provide to each holder
of the bonds copies of the prospectus, notify each holder of the bonds when a
registration statement for the outstanding bonds has become effective and take
certain other actions as are appropriate to permit resale of the outstanding
bonds.

     In the event that any such exchange offer is not commenced or such
registration statement is not declared effective by November 20, 2000, the
exchange offer is not consummated by January 3, 2001 or any such registration
statement ceases to be effective or useable during the specified time period,
the respective annual interest rates on the outstanding bonds will increase by
50 basis points until the date on which such registration statement will have
become effective and is useable or such exchange offer is consummated.

     Each holder of the bonds who wishes to exchange the outstanding bonds for
bonds in the exchange offer will be required to represent that any bonds to be
received by it will be acquired in the ordinary course of business and that at
the time of the commencement of the exchange offer it will have no arrangement
with any person to participate in the distribution (within the meaning of the
Securities Act) of the bonds.

<PAGE>   101

                              PLAN OF DISTRIBUTION


     Each broker-dealer that receives bonds for its own account in the exchange
offer must acknowledge that it will deliver a prospectus in connection with any
resale of the bonds. This prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of bonds
received in exchange for outstanding bonds where such outstanding bonds were
acquired as a result of market-making activities or other trading activities. We
have agreed that, for a period of 90 days after the expiration date of the
exchange offer, we will make this prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any resale. In
addition, until January 23, 2000, all dealers effecting transactions in the
bonds may be required to deliver a prospectus.


     Neither NRG Northeast nor any of the guarantors will receive any proceeds
from any sale of bonds by broker-dealers. Bonds received by broker-dealers for
their own account in the exchange offer may be sold from time to time in one or
more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the bonds or a combination of these methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or at negotiated prices. Any resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any broker-dealer or
the purchasers of any of the bonds. Any broker-dealer that resells bonds that
were received by it for its own account in the exchange offer and any broker or
dealer that participates in a distribution of such bond

          (1) may be deemed to be an "underwriter" within the meaning of the
     Securities Act and

          (2) must acknowledge that it must comply with the registration and
     prospectus delivery requirements of the Securities Act in connection with
     the resale transaction, including the delivery of a prospectus that
     contains information with respect to any selling holder required by the
     Securities Act in connection with any resale transaction.

Furthermore, any broker dealer that acquired any of its outstanding bonds
directly from our company:

     - may not rely on the applicable interpretation of the staff of the SEC's
       position contained in Exxon Capital Holdings Corp., SEC No-Action Letter
       (April 13, 1989), Morgan Stanley & Co., Inc., SEC No-Action Letter (June
       5, 1991) and Shearman & Sterling, SEC No-Action Letter (July 2, 1983) and


     - must also be named a selling holder of bonds in connection with the
       registration and prospectus delivery requirements of the Securities Act
       relating to any resale transaction.


Profit on any resale of the bonds issued in the exchange offer and any
commission or concessions received by any of these persons may be deemed to be
underwriting compensation under the Securities Act. The letter of transmittal
states that, by acknowledging that it will deliver and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.


     For a period of 90 days after the expiration date of the exchange offer NRG
Northeast will promptly send additional copies of this prospectus and any
amendment or supplement to this prospectus to any broker-dealer that requests
these documents in the letter of transmittal. NRG Northeast has agreed to pay
all expenses incident to the exchange offer (including the expenses of one
counsel for the holders of the bonds) other than commissions or concessions of
any broker-dealers and will indemnify the holders of the bonds (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act. We note, however, that, in the opinion of the SEC,
indemnification against liabilities arising under the federal securities laws is
against public policy and may be unenforceable.

                 CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

     The following is a general discussion of certain U.S. federal income tax
considerations relating to the exchange of the outstanding bonds for the bonds
issued in this exchange offer. This discussion is based on laws, regulations,
rulings and decisions now in effect, all of which are subject to change,
possibly with retroactive effect. NRG Northeast has not obtained, nor does it
intend to obtain, a ruling from the IRS as to any U.S. federal income tax
consequences discussed below and there can be no assurances that the IRS will
not take contrary positions. This discussion does not address all aspects of
U.S. federal income tax that may be relevant to particular holders of
outstanding bonds or bonds issued in this exchange offer. This discussion deals
only with holders of bonds who hold the bonds as capital assets and exchange
outstanding bonds for bonds pursuant to this exchange offer. This discussion
does not address the tax consequences arising under the laws of any foreign,
state or local jurisdiction. Prospective investors are urged to consult their
tax advisors regarding the U.S. federal tax consequences of acquiring, holding
and disposing of the bonds, as well as any tax consequences that may arise under
the laws of any foreign, state, local or other taxing jurisdiction.

THE EXCHANGE OFFER

     An exchange of the outstanding bonds for the bonds pursuant to the exchange
offer will not be treated as an "exchange" for U.S. federal income tax purposes
because the terms of the bonds issued in the exchange offer are substantially
identical to the terms of the outstanding bonds. Consequently, a holder of the
outstanding bonds will not recognize taxable gain or loss as a result of
exchanging bonds pursuant to the exchange offer. The holding period of the bonds
issued in the exchange offer will be the same as the holding period of the
outstanding bonds and the tax basis of the bonds will be the same as the basis
in the outstanding bonds immediately before the exchange.

                                 LEGAL MATTERS

     Certain legal matters with respect to the bonds will be passed upon for us
by Skadden, Arps, Slate, Meagher & Flom LLP, New York, New York.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors
and Members of
NRG Northeast Generating LLC:

     In our opinion, the accompanying consolidated balance sheet and the related
consolidated statement of operations, of member's equity and of cash flows
present fairly, in all material respects, the financial position of NRG
Northeast Generating LLC and its subsidiaries at December 31, 1999, and the
results of their operations and their cash flows for the period from April 27,
1999 (Inception) through December 31, 1999 in conformity with accounting
principles generally accepted in the United States. These financial statements
are the responsibility of the Company's management; our responsibility is to
express an opinion on these financial statements based on our audit. We
conducted our audit of these statements in accordance with auditing standards
generally accepted in the United States, which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audit provides a reasonable basis for the opinion expressed
above.

equity for the period from April 27, 1999 to December 31, 1999.

NOTE 1 -- BUSINESS DEVELOPMENTS

     In April 1999, the Somerset facility was acquired for approximately $55
million from Montaup Electric Company ("MEC"). The Somerset facility, located in
Somerset, Massachusetts, includes two coal-fired generating facilities and two
aeroderivative combustion turbine peaking units having a capacity of 160 MW,
excluding 69 MW on deactivated reserve.

     In June 1999, the Huntley and Dunkirk facilities were acquired from Niagara
Mohawk Power Corporation ("NiMo") for approximately $355 million. The two
coal-fired facilities are located near Buffalo, New York, and have a combined
capacity of 1,360 MW.

     In June 1999, the Arthur Kill and the Astoria facilities were acquired for
approximately $505 million from the Consolidated Edison Company of New York,
Inc. ("ConEd"). These facilities, which are located in Staten Island and Queens,
New York, have a combined capacity of 1,456 MW.

     In October 1999, the 1,700 MW capacity oil and gas-fired Oswego facility
was acquired for approximately $85 million from NiMo and Rochester Gas and
Electric Corporation. The facility is located in Oswego, New York.

     In December 1999, affiliates of the Company acquired four fossil fuel
electric generating stations and six remote gas turbines having an aggregate
capacity of 2,235 MW from Connecticut Light & Power Company ("CL&P") for
approximately $460 million, plus adjustments for working capital. These

NOTE 1 -- BUSINESS DEVELOPMENTS -- (CONTINUED)
     On January 19, 2000, NRG announced the execution of an agreement to acquire
1,875 MW of fossil-fueled electric generating capacity and other assets from
Conectiv, an electric utility based in Wilmington, Delaware. NRG has committed
to pay approximately $800 million for these assets, which are currently owned by
Conectiv's subsidiaries, Atlantic City Electric Company and Delmarva Power &
Light Company ("Delmarva"). Under a five-year power purchase agreement, NRG will
sell 500 MW of energy per year to Delmarva.

     While the Company had stated that it was possible that NRG may elect to
contribute or transfer the Conectiv facilities to the Company, NRG has decided
it will not make such contribution or transfer (unaudited).

     During 1999, the Company purchased the above mentioned facilities for an
aggregate purchase price of $1.5 billion. The acquisitions were accounted for as
purchases of assets in the following manner:

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Principles of Consolidation

     The consolidated financial statements include the accounts of the Company

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
  Use of Estimates in Financial Statements

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect reported amounts of assets and liabilities
at the date of the financial statements and reported amounts of revenue and
expenses during the reporting period. Actual results may differ from those
estimates.

  Cash and Cash Equivalents

     The Company considers cash and cash equivalents to include cash and
short-term investments with original maturities of three months or less.

  Inventory

     Inventory consists of spare parts, coal, fuel oil and kerosene and is
stated at the lower of weighted average cost or market (Note 5).

  Prepaid Expenses

     Prepaid expenses include insurance, taxes and other prepayments.

  Derivative Financial Instruments

     Hedge accounting is applied only if the derivative reduces the risk of the
underlying hedged item and is designated at inception as a hedge, with respect
to the hedged item. If a derivative ceased to meet the criteria for deferral,
any gains or losses would be currently recognized in income. The Company does
not hold or issue derivative financial instruments for trading purposes.

  Property, Plant and Equipment

     Property, plant and equipment are stated at cost. Depreciation is computed
on a straight-line basis over the following estimated useful lives:

</TABLE>


     Deferred financing costs consist of legal and other costs incurred by the
Company to obtain short-term financing. These costs are being amortized over the
terms of the related short-term debt.

  Revenue Recognition

     Revenue and related costs are recorded as electricity is generated or
services are provided.

  Power Marketing Activities

     The Company's subsidiaries have entered into contracts with a marketing
affiliate for the sale of energy, capacity and ancillary services produced by
these subsidiaries, which enables the affiliate to engage in forward sales and
hedging transactions to manage the subsidiaries' electricity price exposure. Net
gains or losses on hedges by the marketing affiliate, which are physically
settled, are recognized in the same manner as the hedged item. The Company
receives the net transaction price on all contracts that are physically settled
by its marketing affiliate (Note 6).

  Income Taxes

     The net income or loss of the Company for income tax purposes, along with
any associated tax credits, is included in the tax returns of NRG. Accordingly,
no provision has been made for federal or state income taxes in the accompanying
financial statements.

     As of December 31, 1999, the accompanying financial statements report a
balance of $1,460,483 for net property, plant and equipment. The tax basis of
this property is estimated to be $1,377,804. The primary difference is due to
accelerated tax depreciation.

  New Accounting Pronouncements

     In June 1998, the Financial Accounting Standard Board issued Statement of
Financial Accounting Standard (SFAS) No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement requires that all
derivatives be recognized at fair value in the balance sheet, and that changes
in fair value be recognized either currently in earnings or deferred as a
component of Other Comprehensive Income, depending on the intended use of the
derivative, its resulting designation and its effectiveness. The Company plans
to adopt this standard in 2001, as required. The potential impact of
implementing this statement has not yet been determined.

     In June 2000, the FASB issued SFAS No. 138, "Accounting for Certain
Derivative Instruments and Certain Hedging Activities, an Amendment of FASB
Statement No. 133." This Statement exceeds SFAS 133 in four areas, normal
purchase and sales contracts, definition of interest rate risk, hedging
recognized foreign currency denominated assets and liabilities and hedging
foreign currency risk and

  Interim Results (Unaudited)


     Information as of and for the six months ended June 30, 2000 is unaudited.
The information as of and furnished in the unaudited June 30, 2000 Balance
Sheet, Statement of Income and Cash Flows include all material adjustments,
consisting only of normal recurring accruals, which are, in the opinion of
management, necessary for a fair presentation of such financial statements. The
data disclosed in these notes to the financial statements for this period is
also unaudited.


NOTE 3 -- SHORT TERM BORROWINGS

     At December 31, 1999, the Company had $682.3 million in short-term
borrowings under its credit facility, which had a weighted average interest rate
of 6.86% for the period. The credit facility consists of a $646.6 million term
loan facility and a $35.7 million working capital revolving facility.


     On February 22, 2000 the Company entered into a 364 day $50 million
floating rate working capital revolving facility. The proceeds of this facility
will be used to finance the Company's working capital needs. As of June 30,
2000, the Company has available $50 million under this facility (unaudited).


NOTE 4 -- LONG TERM DEBT

     On February 22, 2000, the Company issued $750 million of senior secured
bonds to refinance short-term project borrowings and for certain other purposes.
The bond offering included three tranches: $320 million with an interest rate of
8.065 percent due in 2004; $130 million with an interest rate of 8.842 percent
due in 2015; and $300 million with an interest rate of 9.292 percent due in
2024. The Company used $646.6 million of the proceeds to repay short-term
borrowings outstanding at December 31, 1999; accordingly $646.6 million of
short-term debt has been reclassified as long-term debt based on the
refinancing.

NOTE 6 -- RELATED PARTY TRANSACTIONS

     The Company's subsidiaries have entered into power sales and agency
agreements with NRG Power Marketing Inc., a wholly-owned subsidiary of NRG. The
agreements are effective until December 31, 2030. Under the agreements, NRG
Power Marketing Inc. will (i) have the exclusive right to manage, market and
sell all power not otherwise sold or committed to or by such subsidiaries, (ii)
procure and provide to such

subsidiaries all fuel required to operate their respective facilities and (iii)
market, sell and purchase all emission credits owned, earned or acquired by such
subsidiaries. In addition, NRG Power Marketing Inc. will have the exclusive
right and obligation to effect the direction of the power output from the
facilities.

     Under the agreements, NRG Power Marketing Inc. pays to the subsidiaries
gross receipts generated through sales, less costs incurred by NRG Power
Marketing Inc. relative to its providing services (e.g. transmission and
delivery costs, fuel cost, taxes, employee labor, contract services, etc.).


     During 1999 and for the six months ended June 30, 2000, the Company
recorded gross receipts less costs incurred from NRG Power Marketing Inc.
totaling $174.8 million and $291.6 million (unaudited), respectively.


     The Company's subsidiaries have entered into operation and maintenance
agreements with subsidiaries of NRG Operating Services, Inc., a wholly-owned
subsidiary of NRG ("NRG Operating Services"). The agreements are effective for
five years, with options to extend beyond five years. Under the agreements, the
NRG Operating Services company operator operates and maintains its respective
facility, including (i) coordinating fuel delivery, unloading and inventory,
(ii) managing facility spare parts, (iii) meeting external performance standards
for transmission of electricity, (iv) providing operating and maintenance
consulting and (v) cooperating with and assisting the Company in performing the
Company's obligations under agreements related to its facilities.

     Under the agreements, the operator will be reimbursed for usual and
customary costs related to providing the services including plant labor and
other operating costs. A demobilization payment will be made if the subsidiary
elects not to renew the agreement. There are also incentive fees and penalties
based on performance under the approved operating budget, the heat rate and
safety.


     During 1999 and for the six months ended June 30, 2000, the Company
incurred operating and maintenance costs billed from NRG Operating Services
totaling $42.7 million and $78.0 million (unaudited), respectively.


     The Company's subsidiaries have entered into agreements with NRG for
corporate support and services. The agreements are perpetual in term, unless
terminated in writing by a subsidiary. Under the agreements, NRG will provide
services, as requested, in areas such as human resources, accounting, finance,
treasury, tax, office administration, information technology, engineering,
construction management, environmental, legal and safety. Under the agreements,
NRG is paid for personnel time as well as out-of-pocket costs.


     During 1999 and for the six months ended June 30, 2000, the Company paid
NRG approximately $1.0 million and $1.5 million (unaudited) for corporate
support and services, respectively.


     Under the terms and conditions of the Company's recently completed bond
offering of $750 million, the Company is obligated to establish a debt service
reserve account for the benefit of the bond holders. This account must contain a
sufficient amount of cash to pay the projected principal and interest on the
bonds due in the next six months. The Company and NRG have entered into an
agreement that provides for an unconditional guarantee of the payment of at
least six-months of projected principal and interest on the bonds. This
guarantee precludes the Company from having to fund the debt service reserve
account with cash. NRG provides this service to the Company and its other
subsidiaries without cost.

NOTE 7 -- BENEFIT PLANS

     The Company does not have any employees. The employees at each of the
operating facilities are employed by NRG Operating Services. The Company has

operate each facility (Note 6). Many of the operating employees were formerly
employed by the previous owner of that facility.

PENSION BENEFITS -- 1999 ACQUISITIONS

     During 1999, subsidiaries of the Company acquired several generating assets
and assumed benefit obligations for a number of employees associated with those
acquisitions. The benefit obligations included noncontributory defined benefit
pension formulas, matched 401(k) savings plans and contributory post-retirement
welfare plans. Approximately 56 percent of the benefit employees are represented
by eight local labor unions under collective bargaining agreements, which expire
between 2000 and 2003.

     NRG Operating Services sponsors one noncontributory defined benefit pension
plan that covers most of the employees associated with the 1999 acquisitions.
Generally, the benefits are based on a combination of years of service, the
final average pay and Social Security benefits. The benefit plan data is shown
below, as the Company will be required to fund the plan under its agreement with
NRG Operating Services.

     The weighted average discount rate used in determining the actuarial
present value of the projected benefit obligation was 7.5% for December 31,
1999. The rate of increase in future compensation levels used in determining the
actuarial present value of the projected obligation was 4.5% for nonunion
employees and 3.50% for union employees. The assumed long-term rate of return on
assets used for cost determination was 8.5% for 1999.

POSTRETIREMENT HEALTH CARE

     Under its agreement with NRG Operating Services, the Company assumed
postretirement health care benefits for some of the employees associated with
the 1999 acquisitions. The plan enables the Company and the retirees to share
the costs of retiree health care. The cost sharing varies by acquisition group
and collective bargaining agreements. There are no existing Company retirees
under these plans as of December 31, 1999. Complete valuation data is not
available for some of these groups. The estimated net periodic postretirement
benefit cost for 1999 is $0.85 million. The estimated accumulated postretirement
benefit obligation is $12 million at December 31, 1999.

401(k) PLANS

     Under its agreement with NRG Operating Services, the Company established
several contributory defined contribution employee savings plans as a result of
its 1999 acquisition activity. These plans comply with Section 401(k) of the
Internal Revenue Code of 1986, as amended, and cover substantially all of the
NRG Operating Service's employees who are not covered by NSP's 401(k) Plan. The
Company matches specified amounts of employee contributions to the plan.
Employer contributions made to the Company's plans were approximately $0.31
million in 1999.

NOTE 8 -- SALES TO SIGNIFICANT CUSTOMERS


     During 1999, sales to three customers accounted for 35.0%, 33.0% and 17.6%
of total revenues in 1999. During 1999, the Company entered into transition
agreements with these customers providing for the sale of energy, capacity and
other ancillary services generated from certain electric generating facilities
recently acquired from these customers and others. These agreements generally
range from four to ten years in duration. For the six months ended June 30,
2000, sales to three customers accounted for 39%, 31% and 17% of total revenues
(unaudited).


NOTE 9 -- DERIVATIVE FINANCIAL INSTRUMENTS

     During the third quarter of 1999, the Company entered into $600 million of
"treasury locks," at various interest rates, which expired in February 2000. The
current market value of these hedges totaled approximately $19.2 million at
December 31, 1999. These treasury locks were an interest rate hedge for the
Company's bond offering that was completed on February 22, 2000. Upon
termination of the treasury locks the Company realized a gain of $21.4 million
which was deferred and is being amortized into income over the term of the
related bonds (unaudited). The proceeds of this bond offering were used to pay
down borrowings under the Company's existing short-term credit facility (Note 3
and Note 4).

     Management believes that the Company's exposure to credit risk due to

NOTE 10 -- CONTINGENT REVENUES

     During 1999, the first year of electricity deregulation in the state of New
York, the Company had claims related to certain revenues earned during the
period April 27, 1999 to December 31, 1999. The Company is actively pursuing
resolution and/or collection of these amounts, which totaled approximately $8.9
million as of December 31, 1999. These amounts have not been recorded in the
financial statements and will not be recognized as income until disputes are
resolved and collection is assured. The contingent revenues relate to
interpretation of certain transition power sales agreements and to sales to the
New York Power Pool ("NYPP") and New England Power Pool ("NEPOOL"), conflicting
meter readings, pricing of firm sales and other power pool reporting issues.

  Retroactive Market Cap (Unaudited)

     On March 30, 2000, the Company received notification from the New York
Independent System Operator (NYISO) of their petition to the Federal Energy
Regulatory Commission (FERC) to place a $2.52 per megawatt hour market cap on
ancillary service revenues. The NYISO also requested authority to impose this
cap on a retroactive basis to March 1, 2000.


     On May 31, 2000, FERC approved the NYISO's request to impose price
limitations on one ancillary service, Ten Minute Non-Synchronized Reserve
(TMNSR) on a prospective basis only, effective March 28, 2000. The FERC rejected
the NYISO's request for authority to adjust the market-clearing prices for TMNSR
on a retroactive basis. As a result of the FERC's order (unless the NYISO or
other party successfully appeals the order) the Company will retain the
approximately $8.0 million of revenues collected in February 2000 and
approximately $8.2 million included in revenues, but not yet collected for March
2000. On June 30, 2000, the NYISO appealed the FERC's decision.


NOTE 11 -- COMMITMENTS AND CONTINGENCIES

  Environmental

     On October 14, 1999, Governor Pataki of New York announced that he is
ordering the New York Department of Environmental Conservation ("NYDEC") to
require further reductions of sulfur dioxide ("SO(2)") emissions and nitrogen
oxide ("NO(x)") emissions from New York power plants, beyond that which is
required under current Federal and state law. The additional reduction
requirement would be phased in between January 1, 2003 and January 1, 2007.
Compliance with these emissions reductions requirements, if they become
effective, could have a material impact on the operation of the Company's
subsidiaries that own certain New York facilities.

     In a letter dated October 12, 1999, the Office of the Attorney General from
the State of New York alleged that, based on a preliminary analysis, it believes
major modifications were made to the Huntley and Dunkirk facilities during
NiMo's ownership of those facilities without obtaining appropriate air permits.
The Company has no reason to believe that NiMo did not comply with the
preconstruction permit requirements for the facilities, and, accordingly, cannot
predict the outcome of this investigation or its financial exposure related to
the claim.

     As a result of alleged historical noncompliance with environmental laws and
regulations, ConEd, the former owner of the Arthur Kill and Astoria facilities,
executed a series of consent orders with the NYDEC

NOTE 11 -- COMMITMENTS AND CONTINGENCIES -- (CONTINUED)
commencing in 1993. The consent orders imposed a number of obligations on ConEd,
including, but not limited to:

     - the evaluation of the impact of water intake screens on aquatic species;

     - the investigation and remediation of spills and releases of petroleum and
       transformer fluids;

     - the evaluation of wastewater discharge points to determine if all such
       locations have been permitted;

     - the inspection and evaluation of above ground petroleum storage tanks and
       performance of testing associated with underground pipelines associated
       with the storage tanks; and

     - compliance with air pollution requirements related to visible emissions.

     The ConEd consent orders include provisions establishing stipulated
penalties for violations of the orders. In connection with the acquisition of
the Arthur Kill and Astoria facilities, Arthur Kill Power and Astoria Gas
Turbine Power assumed certain remaining obligations under the consent orders to
the extent the orders apply to those facilities. These subsidiaries are
currently negotiating a consent order with the NYDEC to memorialize the
commitment they are assuming relative to the ConEd consent orders.

     As a result of alleged violations of opacity, or visible emission,
standards at the Huntley, Dunkirk and Oswego facilities, NiMo, the former owner
and operator of these facilities, was in the process of negotiating a consent
order with NYDEC to resolve such violations at the time we acquired such
facilities. Under the terms of the asset purchase agreements, NiMo will be
responsible for any and all exceedences which occurred prior to the closing of
the transactions contemplated in the asset purchase agreements. The Company's
subsidiaries which own these facilities have agreed, in connection with their
acquisition of these facilities, to enter into separate consent orders for each
facility to address on-going and potential future violations of opacity
standards. The Company believes that almost all of the opacity exceedences at
the Dunkirk and Oswego facilities are non-preventable events occurring as a
result of startups and shutdowns at those facilities that should not be subject
to penalties under the New York regulations. These subsidiaries are currently in
discussions with the NYDEC regarding this issue. Opacity exceedences at the
Huntley Facility are also under discussion with NYDEC.

     Environmental site agreements have been prepared for all of the recently
acquired assets. The remediation activities at the Arthur Kill, Astoria Gas
Turbine and Somerset facilities are still in the study phase. As such, the
remediation cost estimates are based on approaches that have not been approved
yet by the regulatory agencies involved. Data for additional investigations
performed at the Astoria Gas Turbine station and the approach being taken at the
Somerset Station may result in less costly remediation efforts than originally
estimated.

     For the Connecticut facilities, the Company is planning to conduct
additional studies to better quantify remedial need. Such studies include the
preparation of risk assessments to justify remedial actions proposed by the
Company to the Connecticut Department of Environmental Protection and the United
States Environmental Protection Agency.

     The Company has recorded approximately $5.8 million for expected
environmental costs related to site remediation issues at the Arthur Kill,
Astoria and Somerset facilities. These amounts are based on the environmental
assessments for these sites.

     The Company has budgeted approximately $44 million for capital expenditure
between 2000 and 2004 for environmental compliance, which includes the above
remedial investigations, the installation of NO(x) control technology at the
Somerset facility, intake screens at the Dunkirk facility, the resolution of
consent orders for

  Contractual Commitments

     Upon the closing of the acquisition of the generating facilities now owned
by Arthur Kill Power and Astoria Gas Power, Arthur Kill Power and Astoria Gas
Turbine Power entered into agreements with ConEd, the previous owner of the
generating facilities. The agreements obligate Arthur Kill Power and Astoria Gas
Turbine Power to maintain specified levels of generating capability and
availability. ConEd will be billed for the electricity capacity sold to it and
ConEd will bill the respective subsidiary for any capacity deficiency should
capacity be unavailable when called on by ConEd.

     For the next four years, the Company estimates that a significant portion
of the total revenues from the Dunkirk and Huntley facilities will be derived
from four-year transition contracts for capacity and energy. All forward
capacity is sold to NiMo during the transition period, with the remainder of
energy sold to the New York ISO. Each of the following agreements was executed
on June 11, 1999 and extends for a term of four years.

     NRG Power Marketing has entered into an agreement with NiMo to hedge NiMo's
transition to market rates. Under the agreement, NiMo will pay a fixed monthly
price for the capacity and ancillary services provided by NRG Power Marketing.
NRG Power Marketing will pay to NiMo the market price for the related capacity
and ancillary services delivered.

     NRG Power Marketing has entered into a swap agreement with NiMo to hedge
NiMo's transition to market rates. In accordance with the agreement, NiMo will
pay to NRG Power Marketing a fixed monthly price for the capacity and ancillary
services provided to NiMo related to Dunkirk units 1, 2, 3 and 4 and Huntley
units 67 and 68. NRG Power Marketing will pay to NiMo the market price for such
services.

     NiMo may also exercise a call option for an additional swap under which
NiMo will nominate certain amounts of energy for the Dunkirk and Huntley
facilities and will pay to NRG Power Marketing an amount for such energy
determined in accordance with the nominated unit's heat rate curve. NRG Power
Marketing will pay to NiMo the market rates for such energy at the time the
energy was nominated.

     Huntley Power has entered into two agreements with NiMo that gives NiMo the
option to purchase certain quantities of energy generated by Huntley units 65
and 66, during the summer and winter months and Huntley units 67 and 68 during
peak and off peak summer hours.

     Oswego Power has entered into a 4-year transition power sales contract with
NiMo in order to hedge NiMo's transition to market rates. Under the agreement,
NiMo will pay to Oswego Power a fixed monthly price plus start up fees for the
right to claim, at a specified delivery point(s), the installed capacity of unit
5 and for the right to exercise an option for an additional 350 MW of installed
capacity.

     NRG Power Marketing has entered into a wholesale standard offer service
agreement with Blackstone Valley Electric Company, Eastern Edison Company and
Newport Electric Corporation (collectively the EUA Company's). Under the
agreement, NRG Power Marketing is obligated to provide each of the EUA Company's
with firm all-requirements electric service, including capacity, energy,
reserves, line losses and related services necessary to serve a specified share
of the aggregate load attributable to retail customers taking standard offer
service. The price the EUA Company's pay to NRG Power Marketing for each unit of
electricity is a fixed price plus a fuel adjustment factor.

     NRG Power Marketing has entered into a standard offer service wholesale
sales agreement with CL&P pursuant to which NRG Power Marketing will supply CL&P
at fixed prices a specified share of a portion of

CL&P's aggregate retail load. The quantity of power to be supplied is equal to
35% of CL&P's standard offer service load during calendar year 2000, 40% during
calendar years 2001 and 2002 and 45% during calendar year 2003.

     NRG Power Marketing is responsible for delivering the contracted power to a
mutually agreed upon delivery point, at which point title to and liability for
the electricity passes to CL&P. NRG Power Marketing is also responsible for
forecasting for the purposes of meeting its supply obligation and for all the
Independent System Operator (ISO) and the NEPOOL charges and expenses in
connection with the delivery of power. CL&P is responsible for arranging all
delivery services for electricity from the delivery point to retail customers.

     The agreement also requires NRG Power Marketing to either (i) be a member
of the NEPOOL or (ii) have a contract with a member of the NEPOOL for the
duration of the term of the agreement which commences on January 1, 2000 and
expires on December 31, 2003.

  Litigation:

     On or about July 12, 1999, Fortistar Capital Inc., a Delaware corporation
("Fortistar"), filed a Complaint in District Court (Fourth Judicial District,
Hennepin County) in Minnesota against NRG, asserting claims for injunctive
relief and for damages as a result of NRG's alleged breach of a letter agreement
with Fortistar relating to the Oswego Facility. NRG disputes Fortistar's
allegations and has asserted numerous counterclaims.


     A temporary injunction hearing was held on September 27, 1999. The
acquisition of the Oswego facility was closed on October 22, 1999, following
notification to the court of Oswego Power's intention to close on that date. On
January 14, 2000, the court denied Fortistar's request for a temporary
injunction. NRG intends to continue to vigorously defend the suit and believes
Fortistar's claims to be without merit. No trial date has been set.



     On May 25, 2000 the New York Department of Environmental Conservation
issued a Notice of Violation to the Company and the prior owner of the Huntley
and Dunkirk facilities relating to physical changes made at those facilities
prior to the Company's assumption of ownership. The Notice of Violation alleges
that these changes represent major modifications undertaken without obtaining
the regulated permits. Although the Company has a right to indemnification by
the previous owner for fines, penalties, assessments, and related losses
resulting from the previous owner's failure to comply with the applicable permit
requirements, the Company could be required, among other things, to install
specified pollution control technology to further reduce air emissions from the
Dunkirk and Huntley facilities and the Company could become subject to fines and
penalties associated with the current and prior operation of the facilities
(unaudited).

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Use of Estimates in Financial Statements

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect reported amounts of assets and liabilities
at the date of the financial statements and reported amounts of revenue and
expenses during the reporting period. Actual results may differ from those
estimates.

     In recording transactions and balances resulting from business operations,
the Company uses estimates based on the best information available. Estimates
are used for such items as plant depreciable lives, uncollectible accounts and
actuarially determined benefit costs, among others. As better information
becomes available (or actual amounts are determinable), the recorded estimates
are revised. Consequently, operating results can be affected by revisions to
prior accounting estimates.

  Cash and Cash Equivalents

     The Company considers cash and cash equivalents to include cash and
short-term investments with original maturities of three months or less.

  Inventory

     Inventory consists of spare parts and fuel oil and is stated at the lower
of weighted average cost or market (Note 4).

  Prepaid Expenses

     Prepaid expenses include insurance, taxes and other prepayments.

  Property, Plant and Equipment

     Property, plant and equipment are stated at cost. Depreciation is computed
on a straight-line basis over the following estimated useful lives:

  Revenue Recognition

     Revenue and related costs are recorded as electricity is generated or
services are provided.

  Power Marketing Activities

     The Company has entered into a contract with a marketing affiliate for the
sale of energy, capacity and ancillary services produced, which enables the
affiliate to engage in forward sales and hedging transactions to manage the
Company's electricity price exposure. Net gains or losses on hedges by the
marketing affiliate,

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
which are physically settled, are recognized in the same manner as the hedged
item. The Company receives the net transaction price on all contracts that are
physically settled by its marketing affiliate.

  Income Taxes

     The net income or loss of the Company for income tax purposes, along with
any associated tax credits, is included in the tax returns of NRG. Accordingly,
no provision has been made for federal or state income taxes in the accompanying
financial statements.

     As of December 31, 1999, the accompanying financial statements report a
balance of $212,553 for net property, plant and equipment. The tax basis of this
property is estimated to be $204,684. The primary difference is due to
accelerated tax depreciation.

  New Accounting Pronouncements

     In June 1998, the Financial Accounting Standard Board (FASB) issued
Statement of Financial Accounting Standard (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities." This statement requires that all
derivatives be recognized at fair value in the balance sheet, and that changes
in fair value be recognized either currently in earnings or deferred as a
component of Other Comprehensive Income, depending on the intended use of the
derivative, its resulting designation and its effectiveness. The Company plans
to adopt this standard in 2001, as required. The potential impact of
implementing this statement has not yet been determined.

     In June 2000, the FASB issued SFAS No. 138, "Accounting for Certain
Derivative Instruments and Certain Hedging Activities, an Amendment of FASB
Statement No. 133." This Statement amends SFAS 133 in four areas, normal
purchases and sales contracts, definition of interest rate risk, hedging
recognized foreign currency denominated assets and liabilities and hedging
foreign currency risk and intercompany derivatives. The Company plans to adopt
the standard, as required. The potential impact of implementing this standard
has not been determined.


  Interim Results (Unaudited)



     Information as of and for the six months ended June 30, 2000 is unaudited.
The information as of and furnished in the unaudited June 30, 2000 Balance
Sheet, Statement of Income and Cash Flows include all material adjustments,
consisting only of normal recurring accruals, which are, in the opinion of
management necessary for a fair presentation of such financial statements. The
data disclosed in these notes to the financial statements for this period is
also unaudited.


NOTE 3 -- LONG TERM DEBT

     On February 22, 2000, NRG Northeast issued $750 million of senior secured
bonds to refinance short-term project borrowings and for certain other purposes.
The bond offering included three tranches: $320 million with an interest rate of
8.065 percent due in 2004; $130 million with an interest rate of 8.842 percent
due in 2015; and $300 million with an interest rate of 9.292 percent due in
2024. NRG Northeast used $646.6 million of the proceeds to repay short-term
borrowings outstanding at December 31, 1999; accordingly $646.6 million of
short-term debt has been reclassified as long-term debt based on the
refinancing. Each of the subsidiaries of NRG Northeast, of which the Company is
one, jointly and severally guarantee the bonds. The bonds are secured by a
security interest in NRG Northeast's membership or other ownership interest in
its subsidiaries that guarantee the bonds; NRG Northeast's rights under all
intercompany notes between it and its subsidiaries, the power sales and agency
agreements, the operations and maintenance agreements, the corporate services
agreements, the transition power sales contracts entered into by NRG Northeast
and its subsidiaries and the funds administration agreement; the debt service
reserve account; and the revenues from certain power sales contracts entered
into by NRG Power Marketing

NOTE 5 -- RELATED PARTY TRANSACTIONS

     On December 15, 1999 the Company entered into a power sales and agency
agreement with NRG Power Marketing Inc., a wholly-owned subsidiary of NRG. The

     During 1999 and for the six months ended June 30, 2000, the Company
recorded gross receipts less costs incurred from NRG Power Marketing Inc.
totaling $2.5 million and $15.3 million, respectively.


     On December 15, 1999 the Company entered into an operation and maintenance
agreement with a subsidiary of NRG Operating Services, Inc., a wholly-owned
subsidiary of NRG ("NRG Operating Services"). The agreement is effective for

million for corporate support and services, respectively.


NOTE 6 -- BENEFIT PLANS

     The Company does not have any employees. The employees at the operating
facility are employed by NRG Operating Services. NRG Northeast has contracted
with NRG Operating Services to operate the facility (Note 5). Many of the
operating employees were formerly employed by the previous owner of the
facility.

PENSION BENEFITS -- 1999 ACQUISITIONS

     During 1999, subsidiaries of NRG Northeast acquired several generating
assets and assumed benefit obligations for a number of employees associated with
their acquisitions of generating assets. The benefit obligations included
noncontributory defined benefit pension formulas, matched 401(k) savings plans
and contributory post-retirement welfare plans. Approximately 56 percent of the
benefit employees are represented by eight local labor unions under collective
bargaining agreements, which expire between 2000 and 2003.

     NRG Operating Services sponsors one noncontributory defined benefit pension
plan that covers most of the employees associated with the 1999 acquisitions.
Generally, the benefits are based on a combination of years of service, the
final average pay and Social Security benefits. The benefit plan data is shown
below, as NRG Northeast and its respective subsidiaries, including the Company,
will be required to fund the plan under its agreement with NRG Operating
Services.

     The weighted average discount rate used in determining the actuarial
present value of the projected benefit obligation was 7.5% for December 31,
1999. The rate of increase in future compensation levels used in determining the
actuarial present value of the projected obligation was 4.5% for nonunion
employees and 3.5% for union employees. The assumed long-term rate of return on
assets used for cost determination was 8.5% for 1999.

POSTRETIREMENT HEALTH CARE

     Under its agreement with NRG Operating Services, NRG Northeast assumed
postretirement health care benefits for some of the employees associated with
the 1999 acquisitions. The plan enables NRG Northeast and the retirees to share
the costs of retiree health care. The cost sharing varies by acquisition group
and collective bargaining agreements. There are no existing NRG Northeast
retirees under these plans as of December 31, 1999. Complete valuation data is
not available for some of these groups. The estimated net periodic
postretirement benefit cost for 1999 is $0.85 million. The estimated accumulated
postretirement benefit obligation is $12 million at December 31, 1999.

NOTE 6 -- BENEFIT PLANS -- (CONTINUED)
401(k) PLANS

     Under its agreement with NRG Operating Services, NRG Northeast established
several contributory defined contribution employee savings plans as a result of
its 1999 acquisition activity. These plans comply with Section 401(k) of the
Internal Revenue Code of 1986, as amended, and cover substantially all of the
NRG Operating Service's employees who are not covered by Northern States Power's
(NRG's parent) 401(k) Plan. NRG Northeast matches specified amounts of employee
contributions to the plan. Employer contributions made to NRG Northeast's plans
were approximately $0.31 million in 1999.

NOTE 7 -- SALES TO SIGNIFICANT CUSTOMERS


     During 1999, sales to one customer (the previous owner of the generating
facilities) accounted for all of the Company's revenues in 1999. During 1999,
the Company entered into an agreement with the previous owner of the Company's
recently acquired electric generating facility for the sale of energy, capacity
and other ancillary services. This agreement accounted for all of the Company's
revenues during 1999 (Note 8). For the six months ended June 30, 2000 sales to
one customer accounted for 90% of the Company's revenues.


NOTE 8 -- COMMITMENTS AND CONTINGENCIES

  Environmental

     On May 17, 2000, Governor Rowland of Connecticut issued an Executive Order
to the Connecticut Department of Environmental Protection ("CDEP") that requires
the CDEP to develop regulations, applicable to power plants and other major
sources of air pollution, to further reduce emissions of nitrogen oxides and
sulphur dioxides by May 2003. The Executive Order requires reductions of sulphur
dioxides by an amount that is 30% to 50% greater than current commitments. The
Executive Order provides that the CDEP should use market based incentives and a
system of creditable emissions allowances or credits to foster cost effective
reductions. Such legislation could require the Company's facilities located in
Connecticut to rely on more expensive fuels or install additional air pollution
control equipment. If such legislation were to become law and the schedule to
implement it were overly aggressive, the Connecticut facilities could be placed
at a significant competitive disadvantage.

  Contractual Commitments

     NRG Power Marketing has entered into a standard offer service wholesale
sales agreement with CL&P pursuant to which NRG Power Marketing will supply CL&P
at fixed prices a specified share of a portion of CL&P's aggregate retail load.
The quantity of power to be supplied is 35 percent of CL&P's standard offer
service load during calendar year 2000, 40 percent during calendar years 2001
and 2002 and 45 percent during calendar year 2003.

     NRG Power Marketing is responsible for delivering the contracted power to a
mutually agreed upon delivery point at which point title to and liability for
the electricity passes to CL&P. NRG Power Marketing is also responsible for
forecasting for the purpose of meeting its supply obligation and for all
Independent System Operator and NEPOOL charges and expenses in connection with
the delivery of power. CL&P is responsible for arranging all delivery services
for electricity from the delivery point to retail customers.

     The agreement also requires NRG Power Marketing to either (i) be a member
of NEPOOL or (ii) have a contract with a member of the NEPOOL for the duration
of the term of the agreement which commences January 1, 2000 and expires on
December 31, 2003.

respects, the financial position of Huntley Power LLC at December 31, 1999, and
the results of their operations and their cash flows for the period from June
11, 1999 (Inception) through December 31, 1999 in conformity with accounting
principles generally accepted in the United States. These financial statements
are the responsibility of the Company's management; our responsibility is to
express an opinion on these financial statements based on our audit. We
conducted our audit of these statements in accordance with auditing standards
generally accepted in the United States, which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements

management, and evaluating the overall financial statement presentation. We
believe that our audit provides a reasonable basis for the opinion expressed
above.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Use of Estimates in Financial Statements

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect reported amounts of assets and liabilities
at the date of the financial statements and reported amounts of revenue and
expenses during the reporting period. Actual results may differ from those
estimates.

     In recording transactions and balances resulting from business operations,
the Company uses estimates based on the best information available. Estimates
are used for such items as plant depreciable lives, uncollectible accounts and
actuarially determined benefit costs, among others. As better information
becomes available (or actual amounts are determinable), the recorded estimates
are revised. Consequently, operating results can be affected by revisions to
prior accounting estimates.

  Cash and Cash Equivalents

     The Company considers cash and cash equivalents to include cash and
short-term investments with original maturities of three months or less.

  Inventory

     Inventory consists of spare parts, coal and fuel oil and is stated at the
lower of weighted average cost or market (Note 5).

  Prepaid Expenses

     Prepaid expenses include insurance, taxes and other prepayments.

  Property, Plant and Equipment

     Property, plant and equipment are stated at cost. Depreciation is computed
on a straight-line basis over the following estimated useful lives:

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
  Revenue Recognition

     Revenue and related costs are recorded as electricity is generated or
services are provided.

  Power Marketing Activities

     The Company has entered into a contract with a marketing affiliate for the
sale of energy, capacity and ancillary services produced, which enables the
affiliate to engage in forward sales and hedging transactions to manage the
Company's electricity price exposure. Net gains or losses on hedges by the
marketing affiliate, which are physically settled, are recognized in the same
manner as the hedged item. The Company receives the net transaction price on all
contracts that are physically settled by its marketing affiliate.

  Income Taxes

     The net income or loss of the Company for income tax purposes, along with
any associated tax credits, is included in the tax returns of NRG. Accordingly,
no provision has been made for federal or state income taxes in the accompanying
financial statements.

     As of December 31, 1999, the accompanying financial statements report a
balance of $153,533 for net property, plant and equipment. The tax basis of this
property is estimated to be $151,434. The primary difference is due to
accelerated tax depreciation.

  New Accounting Pronouncements

     In June 1998, the Financial Accounting Standard Board (FASB) issued
Statement of Financial Accounting Standard (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities." This statement requires that all
derivatives be recognized at fair value in the balance sheet, and that changes
in fair value be recognized either currently in earnings or deferred as a
component of Other Comprehensive Income, depending on the intended use of the
derivative, its resulting designation and its effectiveness. The Company plans
to adopt this standard in 2001, as required. The potential impact of
implementing this statement has not yet been determined.

     In June 2000, the FASB issued SFAS No. 138, "Accounting for Certain
Derivative Instruments and Certain Hedging Activities, an Amendment of FASB
Statement No. 133." This Statement amends SFAS 133 in four areas, normal
purchases and sales contracts, definition of interest rate risk, hedging
recognized foreign currency denominated assets and liabilities and hedging
foreign currency risk and intercompany derivatives. The Company plans to adopt
the standard, as required. The potential impact of implementing this standard
has not been determined.

NOTE 3 -- SHORT TERM BORROWINGS

     At December 31, 1999, NRG Northeast had $682.3 million in short-term
borrowings under its 364-day credit facility, which had a weighted average
interest rate of 6.86% for the period. Interest on the credit facility is
payable at a variable rate of LIBOR plus 0.125%. The credit facility consists of
a $646.6 million term loan

facility and a $35.7 million working capital revolving facility. On June 11,
1999, the Company borrowed from NRG Northeast approximately $97.1 million of the
$646.6 million term loan facility proceeds pursuant to an intercompany loan
agreement to finance a portion of its purchase of its electric generating
facilities. The terms of the intercompany loan agreement are identical to NRG
Northeast's 364-day credit facility. During 1999, approximately $4.4 million of
interest expense related to the credit facility was recognized as part of the
Company's results of operations.

NOTE 4 -- LONG TERM DEBT

     On February 22, 2000, NRG Northeast issued $750 million of senior secured
bonds to refinance short-term project borrowings and for certain other purposes.
The bond offering included three tranches: $320 million with an interest rate of
8.065 percent due in 2004; $130 million with an interest rate of 8.842 percent
due in 2015; and $300 million with an interest rate of 9.292 percent due in
2024. NRG Northeast used $646.6 million of the proceeds to repay short-term
borrowings outstanding at December 31, 1999; accordingly $646.6 million of
short-term debt has been reclassified as long-term debt based on the
refinancing. Each of the subsidiaries of NRG Northeast, of which the Company is
one, jointly and severally guarantee the bonds. The bonds are secured by a
security interest in NRG Northeast's membership or other ownership interest in
its subsidiaries that guarantee the bonds; NRG Northeast's rights under all
intercompany notes between it and its subsidiaries, the power sales and agency
agreements, the operations and maintenance agreements, the corporate services
agreements, the transition power sales contracts entered into by NRG Northeast
and its subsidiaries and the funds administration agreements; the debt service
reserve account; and the revenues from certain power sales contracts entered
into by NRG Power Marketing associated with existing or future facilities owned
by NRG Northeast or its subsidiaries. A portion of the interest expense related
to these bonds will be recognized as part of the Company's results of
operations.

NOTE 7 -- BENEFIT PLANS

     The Company does not have any employees. The employees at the operating
facility are employed by NRG Operating Services. NRG Northeast has contracted
with NRG Operating Services to operate the facility (Note 6). Many of the
operating employees were formerly employed by the previous owner of the
facility.

PENSION BENEFITS -- 1999 ACQUISITIONS

     During 1999, subsidiaries of NRG Northeast acquired several generating
assets and assumed benefit obligations for a number of employees associated with
their acquisitions of generating assets. The benefit obligations included
noncontributory defined benefit pension formulas, matched 401(k) savings plans
and contributory post-retirement welfare plans. Approximately 56 percent of the
benefit employees are represented by eight local labor unions under collective
bargaining agreements, which expire between 2000 and 2003.

     NRG Operating Services sponsors one noncontributory defined benefit pension
plan that covers most of the employees associated with the 1999 acquisitions.
Generally, the benefits are based on a combination of years of service, the
final average pay and Social Security benefits. The benefit plan data is shown
below, as NRG Northeast and its respective subsidiaries, including the Company,
will be required to fund the plan under its agreement with NRG Operating
Services.

POSTRETIREMENT HEALTH CARE

     Under its agreement with NRG Operating Services, NRG Northeast assumed
postretirement health care benefits for some of the employees associated with
the 1999 acquisitions. The plan enables NRG Northeast and the retirees to share
the costs of retiree health care. The cost sharing varies by acquisition group
and collective bargaining agreements. There are no existing NRG Northeast
retirees under these plans as of December 31, 1999. Complete valuation data is
not available for some of these groups. The estimated net periodic
postretirement benefit cost for 1999 is $0.85 million. The estimated accumulated
postretirement benefit obligation is $12 million at December 31, 1999.

401(k) PLANS


     Under its agreement with NRG Operating Services, NRG Northeast established
several contributory defined contribution employee savings plans as a result of
its 1999 acquisition activity. These plans comply with Section 401(k) of the
Internal Revenue Code of 1986, as amended, and cover substantially all of the
NRG Operating Service's employees who are not covered by Northern States Power's
(NRG's parent) 401(k) Plan. NRG Northeast matches specified amounts of employee
contributions to the plan. Employer contributions made to NRG Northeast's plans
were approximately $0.31 million in 1999.


NOTE 8 -- SALES TO SIGNIFICANT CUSTOMERS


     During 1999, sales to one customer (the previous owner of the generating
facilities) accounted for 67.1 percent of the Company's revenues in 1999. During
1999, the Company entered into a transition agreement with the previous owner of
the Company's recently acquired electric generating facilities for the sale of
energy, capacity and other ancillary services. This transition agreement
accounted for a majority of the Company's revenues during 1999 (Note 9). For the
six months ended June 30, 2000, sales to two customers accounted for 48% and 45%
of the Company's revenues.


NOTE 9 -- COMMITMENTS AND CONTINGENCIES

  Regulatory Issue


     On May 31, 2000, the Federal Energy Regulatory Commission ("FERC") approved
a request of the New York Independent System Operator ("NYISO"), to impose price
limitations on one ancillary service, Ten Minute Non-Synchronized Reserve
("TMNSR"), on a prospective basis effective March 28, 2000. The FERC rejected
the NYISO's request for authority to adjust the market-clearing prices for TMNSR
on a retroactive basis. As a result of the FERC's order (unless the NYISO or
other party successfully appeals the order) NRG Northeast will retain the
approximately $8.0 million of revenues collected in February 2000 and
approximately $8.2 million included in revenues, but not yet collected for March
2000. On June 30, 2000 the NYISO appealed the FERC's decision rejecting its
request to adjust the market clearing prices on a retroactive basis. NRG
Northeast will attempt to revise its business plan to adjust its business
operations to mitigate the future impact of the Order.


  Environmental

     On October 14, 1999, Governor Pataki of New York announced that he is
ordering the New York Department of Environmental Conservation ("NYDEC") to
require further reductions of sulfur dioxide ("SO(2)") emissions and nitrogen
oxide ("NO(x)") emissions from New York power plants, beyond that which is
required under current Federal and state law. These reductions would be phased
in between January 1, 2003 and January 1, 2007. Compliance with these emissions
reductions requirements, if they become effective, could have a material adverse
impact on the operation of the Company's facilities located in the state of New

York. Due to the uncertainties involved in the adoption of these new emission
reduction requirements, the Company is unable to determine what impact these new
requirements may have on the Company's results of operations.

     In a letter dated October 12, 1999, the Office of the Attorney General from
the State of New York alleged that, based on a preliminary analysis, it believes
major modifications were made to the Huntley and Dunkirk facilities during
NiMo's ownership of those facilities without obtaining appropriate air permits.
The Company has no reason to believe that NiMo did not comply with the
preconstruction permit requirements for the facilities, and, accordingly, cannot
predict the outcome of this investigation or its financial exposure related to
the claim.

     As a result of alleged violations of opacity, or visible emission standards
at the Huntley, Dunkirk and Oswego facilities, NiMo, the former owner and
operator of these facilities, was in the process of negotiating a consent order
with NYDEC to resolve such violations at the time we acquired such facilities.
Under the terms of the asset purchase agreements, NiMo will be responsible for
any and all exceedences which occurred prior to the closing of the transactions
contemplated in the asset purchase agreements. The Company's subsidiaries which
own these facilities have agreed, in connection with their acquisition of these
facilities, to enter into separate consent orders for each facility to address
on-going and potential future violations of opacity standards. The Company
believes that almost all of the opacity exceedences at the Dunkirk and Oswego
facilities are non-preventable events occurring as a result of startups and
shutdowns at those facilities that should not be subject to penalties under the
New York regulations. These subsidiaries are currently in discussions with the
NYDEC regarding this issue. Opacity exceedences at the Huntley Facility are also
under discussion with NYDEC.

  Contractual Commitments

     For the next four years, the Company estimates that a significant portion
of the total revenues from the Dunkirk and Huntley facilities will be derived
from four-year transition contracts for capacity and energy. All forward
capacity is sold to NiMo during the transition period, with the remainder of
energy sold to the New York ISO. Each of the following agreements was executed
on June 11, 1999 and extends for a term of four years.

     NRG Power Marketing has entered into an agreement with NiMo to hedge NiMo's

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Use of Estimates in Financial Statements

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect reported amounts of assets and liabilities
at the date of the financial statements and reported amounts of revenue and
expenses during the reporting period. Actual results may differ from those
estimates.

     In recording transactions and balances resulting from business operations,
the Company uses estimates based on the best information available. Estimates
are used for such items as plant depreciable lives, uncollectible accounts and
actuarially determined benefit costs, among others. As better information
becomes available (or actual amounts are determinable), the recorded estimates
are revised. Consequently, operating results can be affected by revisions to
prior accounting estimates.

  Cash and Cash Equivalents

     The Company considers cash and cash equivalents to include cash and
short-term investments with original maturities of three months or less.

  Inventory

     Inventory consists of spare parts, coal and fuel oil and is stated at the
lower of weighted average cost or market (Note 5).

  Prepaid Expenses

     Prepaid expenses include insurance, taxes and other prepayments.

  Property, Plant and Equipment

     Property, plant and equipment are stated at cost. Depreciation is computed
on a straight-line basis over the following estimated useful lives:

  Deferred Financing

     Deferred financing costs consist of legal and other costs incurred to
obtain debt financing. These costs are being amortized over the terms of the
related debt.

  Revenue Recognition

     Revenue and related costs are recorded as electricity is generated or
services are provided.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
  Power Marketing Activities

     The Company has entered into a contract with a marketing affiliate for the
sale of energy, capacity and ancillary services produced, which enables the
affiliate to engage in forward sales and hedging transactions to manage the
Company's electricity price exposure. Net gains or losses on hedges by the
marketing affiliate, which are physically settled, are recognized in the same
manner as the hedged item. The Company receives the net transaction price on all
contracts that are physically settled by its marketing affiliate.

  Income Taxes

     The net income or loss of the Company for income tax purposes, along with
any associated tax credits, is included in the tax returns of NRG. Accordingly,
no provision has been made for federal or state income taxes in the accompanying
financial statements.

     As of December 31, 1999, the accompanying financial statements report a
balance of $183,365 for net property, plant and equipment. The tax basis of this
property is estimated to be $180,530. The primary difference is due to
accelerated tax depreciation.

  New Accounting Pronouncements

     In June 1998, the Financial Accounting Standard Board (FASB) issued
Statement of Financial Accounting Standard (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities." This statement requires that all
derivatives be recognized at fair value in the balance sheet, and that changes
in fair value be recognized either currently in earnings or deferred as a
component of Other Comprehensive Income, depending on the intended use of the
derivative, its resulting designation and its effectiveness. The Company plans
to adopt this standard in 2001, as required. The potential impact of
implementing this statement has not yet been determined.

     In June 2000, the FASB issued SFAS No. 138, "Accounting for Certain
Derivative Instruments and Certain Hedging Activities, an Amendment of FASB
Statement No. 133." This Statement amends SFAS 133 in four areas, normal
purchases and sales contracts, definition of interest rate risk, hedging
recognized foreign currency denominated assets and liabilities and hedging
foreign currency risk and intercompany derivatives. The Company plans to adopt
the standard, as required. The potential impact of implementing this standard
has not been determined.


  Interim Results (Unaudited)



     Information as of and for the six months ended June 30, 2000 is unaudited.
The information as of and furnished in the unaudited June 30, 2000 Balance
Sheet, Statement of Income and Cash Flows include all material adjustments,
consisting only of normal recurring accruals, which are, in the opinion of
management necessary for a fair presentation of such financial statements. The
data disclosed to these notes to the financial statements for this period is
also unaudited.


NOTE 3 -- SHORT TERM BORROWINGS

     At December 31, 1999, NRG Northeast had $682.3 million in short-term
borrowings under its 364-day credit facility, which had a weighted average
interest rate of 6.86% for the period. Interest on the credit facility is
payable at a variable rate of LIBOR plus 0.125%. The credit facility consists of
a $646.6 million term loan facility and a $35.7 million working capital
revolving facility. On June 11, 1999, the Company borrowed from NRG Northeast
approximately $124.1 million of the $646.6 million term loan facility proceeds
pursuant to an intercompany loan agreement to finance a portion of its purchase
of its electric generating facilities. The terms

NOTE 3 -- SHORT TERM BORROWINGS -- (CONTINUED)
of the intercompany loan are identical to NRG Northeast's 364-day credit
facility. During 1999, approximately $5.6 million of interest expense related to
the credit facility was recognized as part of the Company's results of
operations.

NOTE 4 -- LONG TERM DEBT

     On February 22, 2000, NRG Northeast issued $750 million of senior secured
bonds to refinance short-term project borrowings and for certain other purposes.
The bond offering included three tranches: $320 million with an interest rate of
8.065 percent due in 2004; $130 million with an interest rate of 8.842 percent
due in 2015; and $300 million with an interest rate of 9.292 percent due in
2024. NRG Northeast used $646.6 million of the proceeds to repay short-term
borrowings outstanding at December 31, 1999; accordingly $646.6 million of
short-term debt has been reclassified as long-term debt based on the
refinancing. Each of the subsidiaries of NRG Northeast, of which the Company is
one, jointly and severally guarantee the bonds. The bonds are secured by a
security interest in NRG Northeast's membership or other ownership interest in
its subsidiaries that guarantee the bonds; NRG Northeast's rights under all
intercompany notes between it and its subsidiaries, the power sales and agency
agreements, the operations and maintenance agreements, the corporate services
agreements, the transition power sales contracts entered into by NRG Northeast
and its subsidiaries and the funds administration agreement; the debt service
reserve account; and the revenues from certain power sales contracts entered
into by NRG Power Marketing associated with existing or future facilities owned
by NRG Northeast or its subsidiaries. A portion of the interest expense related
to these bonds will be recognized as part of the Company's results of
operations.

NOTE 7 -- BENEFIT PLANS

     The Company does not have any employees. The employees at the operating
facility are employed by NRG Operating Services. NRG Northeast has contracted
with NRG Operating Services to operate the facility (Note 6). Many of the
operating employees were formerly employed by the previous owner of the
facility.

PENSION BENEFITS -- 1999 ACQUISITIONS

     During 1999, subsidiaries of NRG Northeast acquired several generating
assets and assumed benefit obligations for a number of employees associated with
their acquisitions of generating assets. The benefit obligations included
noncontributory defined benefit pension formulas, matched 401(k) savings plans
and contributory post-retirement welfare plans. Approximately 56 percent of the
benefit employees are represented by eight local labor unions under collective
bargaining agreements, which expire between 2000 and 2003.

     NRG Operating Services sponsors one noncontributory defined benefit pension
plan that covers most of the employees associated with the 1999 acquisitions.
Generally, the benefits are based on a combination of years of service, the
final average pay and Social Security benefits. The benefit plan data is shown
below, as NRG Northeast and its respective subsidiaries, including the Company,
will be required to fund the plan under its agreement with NRG Operating
Services.

     The weighted average discount rate used in determining the actuarial
present value of the projected benefit obligation was 7.5% for December 31,
1999. The rate of increase in future compensation levels used in determining the
actuarial present value of the projected obligation was 4.5% for nonunion
employees and 3.50% for union employees. The assumed long-term rate of return on
assets used for cost determination was 8.5% for 1999. During 1999, the Company
recorded approximately $516,000 of pension expense.

NOTE 7 -- BENEFIT PLANS -- (CONTINUED)
POSTRETIREMENT HEALTH CARE

     Under its agreement with NRG Operating Services, NRG Northeast assumed
postretirement health care benefits for some of the employees associated with
the 1999 acquisitions. The plan enables NRG Northeast and the retirees to share
the costs of retiree health care. The cost sharing varies by acquisition group
and collective bargaining agreements. There are no existing NRG Northeast
retirees under these plans as of December 31, 1999. Complete valuation data is
not available for some of these groups. The estimated net periodic
postretirement benefit cost for 1999 is $0.85 million. The estimated accumulated
postretirement benefit obligation is $12 million at December 31, 1999.

401(k) PLANS

     Under its agreement with NRG Operating Services, NRG Northeast established
several contributory defined contribution employee savings plans as a result of
its 1999 acquisition activity. These plans comply with Section 401(k) of the
Internal Revenue Code of 1986, as amended, and cover substantially all of the
NRG Operating Service's employees who are not covered by Northern States Power's
(NRG's parent) 401(k) Plan. NRG Northeast matches specified amounts of employee
contributions to the plan. Employer contributions made to NRG Northeast's plans
were approximately $0.31 million in 1999.

NOTE 8 -- SALES TO SIGNIFICANT CUSTOMERS


     During 1999, sales to one customer (the previous owner of the generating
facilities) accounted for 86.0 percent of the Company's revenues in 1999. During
1999, the Company entered into a transition agreement with the previous owner of
the Company's recently acquired electric generating facilities for the sale of
energy, capacity and other ancillary services. This transition agreement
accounted for a majority of the Company's revenues during 1999 (Note 10). For
the six months ended June 30, 2000 sales to two customers accounted for 68% and
32% of the Company's revenues.


NOTE 9 -- CONTINGENT REVENUES

     During 1999, the first year of electricity deregulation in the state of New
York, NRG Northeast had claims related to certain revenues earned during the
period April 27, 1999 to December 31, 1999. NRG Northeast is actively pursuing
resolution and/or collection of these amounts. These amounts have not been
recorded in the financial statements and will not be recognized as income until
disputes are resolved and collection is assured. The contingent revenues relate
to interpretation of certain transition power sales agreements and to sales to
the New York Power Pool ("NYPP") and New England Power Pool ("NEPOOL"),
conflicting meter readings, pricing of firm sales and other power pool reporting
issues. Approximately $3.5 million of these contingent revenues relate to the
Company.

NOTE 10 -- COMMITMENTS AND CONTINGENCIES

  Regulatory Issue


     On May 31, 2000, the Federal Energy Regulatory Commission ("FERC") approved
a request of the New York Independent System Operator ("NYISO"), to impose price
limitations on one ancillary service, Ten Minute Non-Synchronized Reserve
("TMNSR"), on a prospective basis effective March 28, 2000. The FERC rejected
the NYISO's request for authority to adjust the market-clearing prices for TMNSR
on a retroactive basis. As a result of the FERC's order (unless the NYISO or
other party successfully appeals the order) NRG Northeast will retain the
approximately $8.0 million of revenue collected in February 2000 and
approximately $8.2 million included in revenues, but not yet collected for March
2000. On June 30, 2000 the NYISO appealed the FERC's decision rejecting its
request to adjust the market clearing prices on a

retroactive basis. NRG Northeast will attempt to revise its business plan to
adjust its business operations to mitigate the future impact of the Order.

  Environmental

     On October 14, 1999, Governor Pataki of New York announced that he is
ordering the New York Department of Environmental Conservation ("NYDEC") to
require further reductions of sulfur dioxide ("SO(2)") emissions and nitrogen
oxide ("NO(x)") emissions from New York power plants, beyond that which is
required under current federal and state law. The additional reduction
requirement would be phased in between January 1, 2003 and January 1, 2007.
Compliance with these emissions reductions requirements, if they become
effective, could have a material adverse impact on the operation of the
Company's facilities located in the state of New York. Due to the uncertainties
involved in the adoption of these new emission reduction requirements, the
Company is unable to determine what impact these new requirements may have on
the Company's results of operations.

     In a letter dated October 12, 1999, the Office of the Attorney General from
the State of New York alleged that, based on a preliminary analysis, it believes
major modifications were made to the Huntley and Dunkirk facilities during
NiMo's ownership of those facilities without obtaining appropriate air permits.
The Company has no reason to believe that NiMo did not comply with the
preconstruction permit requirements for the facilities, and, accordingly, cannot
predict the outcome of this investigation or its financial exposure related to
the claim.

     As a result of alleged violations of opacity, or visible emission,
standards at the Huntley, Dunkirk and Oswego facilities, NiMo, the former owner
and operator of these facilities, was in the process of negotiating a consent
order with NYDEC to resolve such violations at the time we acquired such
facilities. Under the terms of the asset purchase agreements, NiMo will be
responsible for any and all exceedences which occurred prior to the closing of
the transactions contemplated in the asset purchase agreements. The Company's
subsidiaries which own these facilities have agreed, in connection with their
acquisition of these facilities, to enter into separate consent orders for each
facility to address on-going and potential future violations of opacity
standards. The Company believes that almost all of the opacity exceedences at
the Dunkirk and Oswego facilities are non-preventable events occurring as a
result of startups and shutdowns at those facilities that should not be subject
to penalties under the New York regulations. These subsidiaries are currently in
discussions with the NYDEC regarding this issue. Opacity exceedences at the
Huntley Facility are also under discussion with NYDEC.

  Contractual Commitments

     For the next four years, the Company estimates that a significant portion
of the total revenues from the Dunkirk and Huntley facilities will be derived
from four-year transition contracts for capacity and energy. All forward
capacity is sold to NiMo during the transition period, with the remainder of
energy sold to the New York ISO. Each of the following agreements was executed
on June 11, 1999 and extends for a term of four years.

     NRG Power Marketing has entered into an agreement with NiMo to hedge NiMo's
transition to market rates. Under the agreement, NiMo will pay a fixed monthly
price for the capacity and ancillary services provided by NRG Power Marketing.
NRG Power Marketing will pay to NiMo the market price for the related capacity
and ancillary services delivered.

     NRG Power Marketing has entered into a swap agreement with NiMo to hedge
NiMo's transition to market rates. In accordance with the agreement, NiMo will
pay to NRG Power Marketing a fixed monthly

price for the capacity and ancillary services provided to NiMo related to
Dunkirk units 1, 2, 3 and 4 and Huntley units 67 and 68. NRG Power Marketing
will pay to NiMo the market price for such services.

     NiMo may also exercise a call option for an additional swap under which
NiMo will nominate certain amounts of energy for the Dunkirk and Huntley
facilities and will pay to NRG Power Marketing an amount for such energy
determined in accordance with the nominated unit's heat rate curve. NRG Power
Marketing will pay to NiMo the market rates for such energy at the time the
energy was nominated.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Use of Estimates in Financial Statements

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect reported amounts of assets and liabilities
at the date of the financial statements and reported amounts of revenue and
expenses during the reporting period. Actual results may differ from those
estimates.

     In recording transactions and balances resulting from business operations,
the Company uses estimates based on the best information available. Estimates
are used for such items as plant depreciable lives, uncollectible accounts and
actuarially determined benefit costs, among others. As better information
becomes available (or actual amounts are determinable), the recorded estimates
are revised. Consequently, operating results can be affected by revisions to
prior accounting estimates.

  Cash and Cash Equivalents

     The Company considers cash and cash equivalents to include cash and
short-term investments with original maturities of three months or less.

  Inventory

     Inventory consists of spare parts and is stated at the lower of weighted
average cost or market (Note 5).

  Prepaid Expenses

     Prepaid expenses include insurance, taxes and other prepayments.


  Interim Results (Unaudited)

  Deferred Financing

     Deferred financing costs consist of legal and other costs incurred to
obtain debt financing. These costs are being amortized over the terms of the
related debt.

  Revenue Recognition

     Revenue and related costs are recorded as electricity is generated or
services are provided.

  Power Marketing Activities

     The Company has entered into a contract with a marketing affiliate for the
sale of energy, capacity and ancillary services produced, which enables the
affiliate to engage in forward sales and hedging transactions to manage the
Company's electricity price exposure. Net gains or losses on hedges by the
marketing affiliate, which are physically settled, are recognized in the same
manner as the hedged item. The Company receives the net transaction price on all
contracts that are physically settled by its marketing affiliate.

  Income Taxes

     The net income or loss of the Company for income tax purposes, along with
any associated tax credits, is included in the tax returns of NRG. Accordingly,
no provision has been made for federal or state income taxes in the accompanying
financial statements.

     As of December 31, 1999, the accompanying financial statements report a
balance of $401,000 for net property, plant and equipment. The tax basis of this
property is estimated to be $394,802. The primary difference is due to
accelerated tax depreciation.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
  New Accounting Pronouncements

     In June 1998, the Financial Accounting Standard Board (FASB) issued
Statement of Financial Accounting Standard (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities." This statement requires that all
derivatives be recognized at fair value in the balance sheet, and that changes
in fair value be recognized either currently in earnings or deferred as a
component of Other Comprehensive Income, depending on the intended use of the
derivative, its resulting designation and its effectiveness. The Company plans
to adopt this standard in 2001, as required. The potential impact of
implementing this statement has not yet been determined.

     In June 2000, the FASB issued SFAS No. 138, "Accounting for Certain
Derivative Instruments and Certain Hedging Activities, an Amendment of FASB
Statement No. 133." This Statement amends SFAS 133 in four areas, normal
purchases and sales contracts, definition of interest rate risk, hedging
recognized foreign currency denominated assets and liabilities and hedging
foreign currency risk and intercompany derivatives. The Company plans to adopt
the standard, as required. The potential impact of implementing this standard
has not been determined.

NOTE 3 -- SHORT TERM BORROWINGS

     At December 31, 1999, NRG Northeast had $682.3 million in short-term
borrowings under its credit facility, which had a weighted average interest rate
of 6.86% for the period. The credit facility consists of a $646.6 million term
loan facility and a $35.7 million working capital revolving facility. The
Company borrowed from NRG Northeast approximately $249.5 million of the $646.6
million term loan facility proceeds pursuant to an intercompany loan agreement
to finance a portion of its purchase of its electric generating facilities.
During 1999, approximately $10.7 million of interest expense related to the
credit facility was recognized as part of the Company's results of operations.

NOTE 4 -- LONG TERM DEBT

     On February 22, 2000, NRG Northeast issued $750 million of senior secured
bonds to refinance short-term project borrowings and for certain other purposes.
The bond offering included three tranches: $320 million with an interest rate of
8.065 percent due in 2004; $130 million with an interest rate of 8.842 percent
due in 2015; and $300 million with an interest rate of 9.292 percent due in
2024. NRG Northeast used $646.6 million of the proceeds to repay short-term
borrowings outstanding at December 31, 1999; accordingly $646.6 million of
short-term debt has been reclassified as long-term debt based on the
refinancing. Each of the subsidiaries of NRG Northeast, of which the Company is
one, jointly and severally guarantee the bonds. The bonds are secured by a
security interest in NRG Northeast's membership or other ownership interest in
its subsidiaries that guarantee the bonds; NRG Northeast's rights under all
intercompany notes between it and its subsidiaries, the power sales and agency
agreements, the operations and maintenance agreements, the corporate services
agreements, the transition power sales contracts entered into by NRG Northeast
and its subsidiaries and the funds administration agreement; the debt service
reserve account; and the revenues from certain power sales contracts entered
into by NRG Power Marketing associated with existing or future facilities owned
by NRG Northeast or its subsidiaries. A portion of the interest expense related
to these bonds will be recognized as part of the Company's results of
operations.

NOTE 7 -- BENEFIT PLANS

     The Company does not have any employees. The employees at the operating
facility are employed by NRG Operating Services. NRG Northeast has contracted
with NRG Operating Services to operate the facility (Note 6). Many of the
operating employees were formerly employed by the previous owner of the
facility.

PENSION BENEFITS -- 1999 ACQUISITIONS

     During 1999, subsidiaries of NRG Northeast acquired several generating
assets and assumed benefit obligations for a number of employees associated with
those acquisitions. The benefit obligations included noncontributory defined
benefit pension formulas, matched 401(k) savings plans and contributory post-
retirement welfare plans. Approximately 56 percent of the benefit employees are
represented by eight local labor unions under collective bargaining agreements,
which expire between 2000 and 2003.

     NRG Operating Services sponsors one noncontributory defined benefit pension
plan that covers most of the employees associated with the 1999 acquisitions.
Generally, the benefits are based on a combination of years of service, the
final average pay and Social Security benefits. The benefit plan data is shown
below, as NRG Northeast and its respective subsidiaries, will be required to
fund the plan under its agreement with NRG Operating Services.

     The weighted average discount rate used in determining the actuarial
present value of the projected benefit obligation was 7.5% for December 31,
1999. The rate of increase in future compensation levels used in determining the
actuarial present value of the projected obligation was 4.5% for nonunion
employees and 3.50% for union employees. The assumed long-term rate of return on
assets used for cost determination was 8.5% for 1999. During 1999, the Company
recorded approximately $350,000 of pension expense.

POSTRETIREMENT HEALTH CARE

     Under its agreement with NRG Operating Services, NRG Northeast assumed
postretirement health care benefits for some of the employees associated with
the 1999 acquisitions. The plan enables NRG Northeast and the retirees to share
the costs of retiree health care. The cost sharing varies by acquisition group
and collective bargaining agreements. There are no existing NRG Northeast
retirees under these plans as of December 31, 1999. Complete valuation data is
not available for some of these groups. The estimated net periodic
postretirement benefit cost for 1999 is $0.85 million. The estimated accumulated
postretirement benefit obligation is $12 million at December 31, 1999.

401(k) PLANS

     Under its agreement with NRG Operating Services, NRG Northeast established
several contributory defined contribution employee savings plans as a result of
its 1999 acquisition activity. These plans comply with Section 401(k) of the
Internal Revenue Code of 1986, as amended, and cover substantially all of the
NRG Operating Service's employees who are not covered by NSP's 401(k) Plan. NRG
Northeast matches specified amounts of employee contributions to the plan.
Employer contributions made to NRG Northeast's plans were approximately $0.31
million in 1999.

NOTE 8 -- SALES TO SIGNIFICANT CUSTOMERS


     During 1999, sales to two customers accounted for 80.9 (the previous owner
of the generating facilities) and 18.7 percent of the Company's revenues during
1999. During 1999, the Company entered into a transition agreement with the
previous owner of the Company's recently acquired electric generating facility
for the sale of energy, capacity and other ancillary services. The transition
agreement accounted for the majority of the Company's revenues during 1999. For
the six months ended June 30, 2000 sales to two customers accounted for 72% and
28% of the Company's revenues.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 9 -- COMMITMENTS AND CONTINGENCIES

  Regulatory issue


     On May 31, 2000, the Federal Energy Regulatory Commission ("FERC") approved
a request of the New York Independent System Operator ("NYISO"), to impose price
limitations on one ancillary service, Ten Minute Non-Synchronized Reserve
("TMNSR"), on a prospective basis effective March 28, 2000. The FERC rejected
the NYISO's request for authority to adjust the market-clearing prices for TMNSR
on a retroactive basis. As a result of the FERC's order (unless the NYISO or
other party successfully appeals the order) NRG Northeast will retain the
approximately $8.0 million of revenues collected in February 2000 and
approximately $8.2 million included in revenues, but not yet collected for March
2000. On June 30, 2000 the NYISO appealed the FERC's decision rejecting its
request to adjust the market clearing prices on a retroactive basis. NRG
Northeast will attempt to revise its business plan to adjust its business
operations to mitigate the future impact of the Order.


  Contractual Commitments

     Upon the closing of the acquisition of the generating facilities now owned
by the Company, the Company entered into an agreement with ConEd, the previous
owner of the generating facilities. The agreement obligates the Company to
maintain specified levels of generating capability and availability. During
certain periods, ConEd will purchase specified amounts of capacity, as long as
the capacity is counted in the installed capacity requirement for New York City.
The Company may use electric capacity other than that generated by its own
plants to satisfy ConEd's demands.

  Environmental

     On October 14, 1999, Governor Pataki of New York announced that he is
ordering the New York Department of Environmental Conservation ("NYDEC") to
require further reductions of sulfur dioxide ("SO(2)") emissions and nitrogen
oxide ("NO(x)") emissions from New York power plants, beyond that which is
required under current Federal and state law. These reductions would be phased
in between January 1, 2003 and January 1, 2007. Compliance with these emissions
reductions requirements, if they become effective, could have a material adverse
impact on the operation of the Company's facilities located in the state of New
York. Due to the uncertainties involved in the adoption of these new emission
reduction requirements, the Company is unable to determine what impact these new
requirements may have on the Company's results of operations.

     In connection with the acquisition of the Company's facilities from ConEd,
the Company assumed ConEd's remaining obligations under certain consent orders
issued to ConEd by the New York Department of Environmental Conservation.

     In connection with these environmental obligations, the Company has
recorded approximately $1.5 million for expected environmental costs related to
site remediation issues at the facility. This amount was recorded based on an
environmental assessment performed by the previous owner of the facilities which
determined that there existed elevated levels of certain metals in the ground
water and surface water in certain areas of the facility.

  ITEM 22. UNDERTAKINGS

     The undersigned registrants hereby undertake:

          (1) To file during any period in which offers or sales are being made,
     a post-effective amendment to this registration statement:

             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;

             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities would not exceed that which was registered)
        and any deviation from the low or high end of the estimated maximum
        offering range may be reflected in the form of prospectus filed with the
        Commission pursuant to Rule 424(b) if, in the aggregate, the changes in
        volume and price represent no more than 20 percent change in the maximum
        aggregate offering price set forth in the "Calculation of Registration
        Fee" table in the effective registration statement;

             (iii) To include any material information with respect to the plan
        of distribution previously disclosed in the registration statement or
        any material change to such information in the registration statement.

          (2) That, for the purpose of determining any liabilities under the
     Securities Act of 1933, each post-effective amendment will be deemed to be
     a new registration statement relating to the securities offered

                                      II-7
<PAGE>   198

     therein, and the offering of such securities at that time will be deemed to
     be the initial bona fide offering thereof.

          (3) To remove from the registration by means of a post-effective
     amendment any of the securities being registered which remain unsold at the
     termination of the offering.

     The undersigned registrants hereby undertake that:

          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Company pursuant to Rule 424(b)(1) or (4)
     or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.

          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

     The undersigned registrants hereby undertake to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this Form, within one business day of the receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

     The undersigned registrants hereby undertake to supply by means of
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 20 above, or otherwise,
the registrants have been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrants will, unless in
the opinion of counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
