             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
             ----------------------------------------------------



NOTE 1.   MANAGEMENT'S STATEMENT
- --------------------------------

    In the opinion of the management of Sierra Pacific Resources, hereafter
known as the Company, the accompanying unaudited interim condensed consolidated
financial statements contain all adjustments (consisting of only normal
recurring adjustments) necessary to present fairly the condensed consolidated
financial position, condensed consolidated results of operations and condensed
consolidated cash flows for the periods shown. These condensed consolidated
financial statements do not contain the complete detail or footnote disclosure
concerning accounting policies and other matters which are included in full year
financial statements and therefore, they should be read in conjunction with the
audited financial statements included in Nevada Power Company's Annual Report on
Form 10-K for the year ended December 31, 1998.

     The results of operations for the three-month and nine-month period ended
September 30, 1999 are not necessarily indicative of the results to be expected
for the full year.

                          Principles of Consolidation
                          ---------------------------

    The condensed consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiaries, Nevada Power Company (NVP), Sierra
Pacific Power Company (SPPC), Tuscarora Gas Pipeline Company, Sierra Gas Holding
Company (formerly Sierra Energy Company), Sierra Energy Company dba e.three,
Sierra Pacific Energy Company, Lands of Sierra, and Sierra Water Development
Company.  All significant intercompany transactions and balances have been
eliminated in consolidation.

                               Reclassifications
                               -----------------

     Certain items previously reported for years prior to 1999 have been
reclassified to conform with the current year's presentation.  Net income and
shareholders' equity were not affected by these reclassifications.


NOTE 2.   SIERRA PACIFIC RESOURCES AND NEVADA POWER COMPANY MERGER
- ------------------------------------------------------------------

     On July 28, 1999 the merger between the Company and NVP was finalized.  The
merger was accounted for as a reverse purchase under generally accepted
principles, with NVP considered the acquiring entity even though the Company is
the surviving legal entity.  In addition, for accounting purposes the merger was
deemed to have occurred on August 1, 1999.  As a result of this reverse purchase
accounting treatment; (i) the historical financial statements the Company for
periods prior to the date of the merger are no longer the financial statements
of the Company, and therefore, are no longer presented; (ii) the historical
financial statements of the Company for periods prior to the date of the merger
are those of NVP. (iii) based on a merger date of August 1, 1999, the
Consolidated Statements of Income for the three and nine months ended September
30, 1999 include two months (August and September 1999) of operating activity
for the Company and its subsidiaries other than NVP.  The same statements
include the operating results of NVP for the entire periods presented.

     On June 11, 1999, following approvals from the Department of Justice and
the SEC, the Public Utilities Commission of Nevada (PUCN) gave unanimous
approval of a stipulation amoung the merging companies, PUCN staff and the
Utility Consumer Advocate, regarding the merging companies' joint divestiture
plan.  As part of the stipulation, the companies were required to re-file the
divestiture plan and file the final Independent System Administrator (ISA)
proposal with the PUCN and the Federal Energy Regulatory Commission (FERC).  The
last filing was submitted in October 1999.  The PUCN merger order provides that
upon selling the generating units, both companies (Sierra Pacific Power and
Nevada Power, also referred to as the utilities) can determine how they will use
the proceeds of the sales, up to the book value of the plants.  Any after-tax
gains above book value will be used to offset stranded costs, as determined by
the PUCN.  The PUCN order also provided that any remaining gains can be used to
offset goodwill.  After-tax gains may not be sufficient to offset goodwill.
However, if the

                                       5
<PAGE>

Company demonstrates that the divestiture "resulted in a market for generation
services that produced market prices that are lower than what could have been
achieved otherwise, the Company may include in the general rate a request to
recover goodwill." The Company expects that most of the generation facility
sales will be completed by late-2000. Following the issuance of the PUCN order
on the merger, the Nevada Legislature passed SB 438 which amended the
restructuring process in Nevada. Among other provisions, it required the
utilities to provide last resort service at a capped price, and provided that
any shortfall experienced by the utilities in revenues from the capped rates
over experienced costs could be recovered from the net gain from the generation
divestiture. It is the utilities' position that any net gain must first be
applied to any such shortfall; any remaining net gain may then be used to offset
stranded costs and then allocated to goodwill.

     Under terms of the stipulation, the merged company is required to file a
general rate case three years after the start of retail competition in the state
of Nevada that would give the merged company the opportunity to recover costs of
the merger, provided the merged company can demonstrate that merger savings
exceed merger costs.  Merger costs are to be split among the non-competitive,
potentially competitive and unregulated services or businesses.  An opportunity
to recover the non-competitive portion of the merger costs will be addressed in
the rate case that follows the start of competition in Nevada.  The burden is on
the merged company to prove that merger savings exceed merger costs.  The merged
company will also have the opportunity to recover goodwill in the same
proceeding.

     Through September 30, 1999 the Company had incurred a total of $52.3
million in capitalized costs since merger work began.  The capitalized merger
amounts consist of $33.2 million of transaction and transition costs and $19.1
million of employee separation costs.

     Employee separation, relocation, and related costs for the Company were
$14.6 million, of which $5.5 million remains unpaid as of September 30, 1999.
Other costs incurred in connection with employee separations included pension
and postretirement benefits net of curtailment gains of $4.5 million.

     In accordance with the terms of the merger, each outstanding share of the
Company's common stock was converted into the right to receive either $37.55 in
cash or 1.44 shares of newly issued Company common stock. Each outstanding share
of NVP common stock was converted to the right receive either $26.00 in cash or
1.00 share of newly issued Company common stock.  4,037,000 shares of Company
and 11,716,611 shares of NVP common stock were exchanged for $151.6 million and
$304.6 million, respectively.  The remaining shares of each company were
converted to newly issued shares of Company common stock.  Company stockholders
and NVP stockholders received 38,866,054 and 39,548,506 shares of newly issued
Company common stock, resulting in 78,414,560 outstanding shares of the Company
on August 1, 1999.


     The total consideration paid to Company common stockholders was equal to
cash of $151.6 million and 38,866,054 shares of newly issued Company common
stock at a price of $24.18 per share based on the average closing price of NVP
common stock between April 22, 1998 and May 6, 1998.  The eleven day average
price of NVP common stock used in determining the total stock consideration
represents the market price over a reasonable period of time before and after
the transaction was announced on April 29, 1998.  As shown below, $331.2 million
of goodwill was recorded in connection with the merger and is being amortized
over 40 years.  However, the Public Utilities Commission's order approving the
merger allowed the Company to defer merger costs (including goodwill) allocable
to the regulated utilities for a three year period.  At the end of the deferral
period the Company will propose an amortization period for goodwill and other
merger costs.  Accordingly, goodwill amortization associated with the regulated
utility companies is being reclassified to a regulatory asset during the three
year period.   Also, because the Company is deferring merger costs as regulatory
assets the transaction costs included in the calculation of goodwill represent
only costs allocable to the Company's non-regulated subsidiaries.   The
calculation of goodwill follows.

NOTE 3.   RECENT PRONOUNCEMENTS OF THE FASB
- -------------------------------------------

    In June 1998, the Financial Accounting Standards Board issued SFAS 133,
entitled "Accounting for Derivative Instruments and Hedging Activities".  This
statement establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts (collectively referred to as derivatives), and for hedging activities.
It requires an entity to recognize all derivatives as either assets or
liabilities in the statement of financial position, and measure those
instruments at fair value.  In May 1999, members of the Financial Accounting
Standards agreed to delay the effective date of Statement 133 to fiscal years
beginning after June 15, 2000.  The Company is still assessing the impact of
SFAS 133 on its financial condition and results of operations.

NOTE 4.   LONG TERM DEBT
- ------------------------

     On July 12, 1999, $10 million of SPPC 6.86% medium term notes matured.  On
July 16, 1999, $20 million of SPPC's 6.83% medium term notes matured.

    On September 17, 1999, SPPC issued $100million floating rate notes, due
October 13, 2000.  Interest on the Notes is payable quarterly in arrears
commencing on December 15, 1999.  The interest rate on the notes for each
interest period to maturity will be a floating rate, subject to adjustment every
three months, equal to the London InterBank Offered Rate for three-month U.S.
dollar deposits (LIBOR) plus a spread of 0.75%.  These notes will not be
entitled to any sinking fund and will be redeemable without premium at the
option of SPPC, in whole, beginning on March 15, 2000 and on the 15/th/ day of
each month thereafter.

     On October 1, 1999, NVP redeemed $45,000,000  Series Y, 6.93%, in first
mortgage bonds.

     On October 15, 1999, NVP issued $100 million floating rate notes, Due
October 6, 2000.  Interest on the notes is payable quarterly in arrears
commencing on January 15, 2000.  The interest rate on the notes for each
interest period to maturity will be a floating rate, subject to adjustment every
three months, equal to LIBOR for U.S. dollar deposits plus a spread of 0.79%.
These notes will not be entitled to any sinking fund and will be redeemable at
the option of NVP, in whole, beginning on April 15, 2000 and on the 15/th/ day
of each month thereafter. The proceeds of this financing will be used to pay
down commercial paper.

NOTE 5.   SHORT-TERM BORROWINGS
- -------------------------------

     On July 28, 1999, immediately following the consummation of the merger with
NVP, the Company put into place a $500 million unsecured revolving credit
facility.  This facility may be used for working capital and general corporate
purposes, including for commercial paper backup, and replaced the Company's
existing credit facility.  At the same time, SPPC and NVP each put into place
$150 million unsecured revolving credit facilities.  These two facilities may
also be used for working capital and general corporate purposes, including for
commercial paper backup, and replaced all existing credit facilities for those
companies.  In addition, immediately following the merger, the Company and NVP
established new commercial paper programs, SPPC revised its existing commercial
paper program, and the Company issued $456.2 million of commercial paper, at an
average interest rate of 5.48%, to provide temporary funding of the cash portion
of the merger consideration.

NOTE 6.   COMMITMENTS AND CONTINGENCIES
- ---------------------------------------

    The Grand Canyon Trust and Sierra Club filed a lawsuit in the U.S. District
Court, District of Nevada, in February 1998, against the owners of the Mohave
Generation Station (including NVP), alleging violations of the Clean Air Act
regarding emissions of sulfur dioxide and particulates.  An additional
plaintiff, National Parks and Conservation Association, later joined the suit.
The plant owners and plaintiffs have had numerous settlement discussions and
filed a proposed settlement with the court on October 6, 1999.  The consent
decree, if approved by the court, would establish emission limits for sulfur
dioxide and opacity and would require installation of air pollution controls for
sulfur dioxide, nitrogen oxides and particulate matter.  The new emission limits
must be met by January 1, 2006 and April 1, 2006, for the first and second
units, respectively.  However, if the owners sell their entire ownership
interest, with a closing date prior to December 30, 2002, then the new emission
limits become effective 36 months and 39 months from the date of last closing
for the two respective units.  The estimated cost of new controls is $300
million.  As a 14% owner in the Mohave Station, NVP's costs could be $42
million.

    Also, the United States Congress authorized the Environmental Protection
Agency (EPA) to study the potential impact Mohave may have on visibility in the
Grand Canyon area.  A final report of the study results was released in March
1999.  The study acknowledges that sulfur dioxide emissions from Mohave are
transported to the Grand Canyon.  EPA has solicited information to determine
whether visibility impairment in the Grand Canyon can be reasonably attributed
to Mohave.  If EPA determines that significant visibility impairment is
reasonably attributable to the station, EPA could initiate a review for Best
Available Retrofit Technology .  The Plant owners believe that settlement of the
suit discussed above is acceptable to the EPA.  Provisions that are

                                       8
<PAGE>

agreed to in a settlement are expected to be reflected in a State Implementation
Plan for Nevada and resolve any concerns of EPA regarding visibility impairment.

    In May 1997, the NDEP ordered NVP to submit a plan to eliminate the
discharge of Reid Gardner Station wastewater to groundwater.  The Order also
required a hydrological assessment of groundwater impacts in the area.  In June
1999, NDEP determined that wastewater ponds have degraded groundwater quality.
In August 1999, NDEP issued a discharge permit to Reid Gardner Station and an
Order which requires all wastewater ponds to be closed or lined with impermeable
liners over the next 10 years.  This Order also required the Company to submit a
Site Characterization Plan to NDEP on October 25, 1999.  Technical information
from the Plan will be used to develop a corrective action plan and allow the
Company to determine an estimate of remediation costs.

    Also, at the Reid Gardner Station, the NDEP has determined that there is
additional groundwater contamination that resulted from oil spills at the
facility.  NDEP has required NVP to submit a corrective action plan by October
25, 1999.  The extent of contamination has not yet been determined.  However,
remediation costs could be material.

    In 1991, the EPA published an order requiring the Navajo Generating Station
(Navajo) to install scrubbers to remove 90 percent of sulfur dioxide emission
beginning in 1997.  As an 11.3 percent owner of Navajo, the Company was required
to fund $48 million for installation of the scrubbers.  The first of three
scrubber units was placed in commercial operation in November 1997; the second
scrubber in September 1998, and the last scrubber unit was placed in operation
June 1999.  The Company spent approximately $46.7 million on the scrubbers'
construction.  In 1992, the Company received resource planning approval from the
PUCN for its share of the cost of the scrubbers.

     It should be noted that the Company has definitive plans to sell its
generating facilities under unrelated regulatory orders.  The sales price of the
plant facilities will likely be adjusted to reflect costs discussed above.

    NVP recently determined that, while constructing the McCullough-Arden
transmission line, access roads were created within a wilderness study area in
violation of the Bureau of Land Management (BLM) Right of Way Grant.  NVP's
preliminary estimate for restoration costs is $200,000 which was reserved as of
September 30, 1999.  BLM enforcement action is pending and may result in a fine.

     Nevada Electric Investment Company (NEICO), a subsidiary of NVP, owns
property in Wellington, Utah which was the site of a coal washing and load out
facility.  The site now has a reclamation estimate supported by a bond of $4.9
million with the Utah Division of Oil and Gas Mining.  The property was under
contract for sale and the contract required the purchaser to provide $1.3
million in escrow towards reclamation.  However, the sales contract was recently
terminated and NEICO has taken title to the escrow funds.  Because it is NEICO's
intention to sell the property it has not provided a reserve for reclamation as
of the date of this report.

NOTE 7.   EARNINGS PER SHARE
- ----------------------------

    The Company follows SFAS No. 128, "Earnings Per Share".  The difference
between Basic EPS and Diluted EPS is due to common stock equivalent shares
resulting from stock options, employee stock purchase plan, performance shares
and a non-employee director stock plan.  Common stock equivalents were
determined using the treasury stock method.

NOTE 8.   SEGMENT INFORMATION
- -----------------------------

     The Company operates three business segments providing regulated electric,
natural gas and water service.  Electric service is provided to Las Vegas and
surrounding Clark County, northern Nevada and the Lake Tahoe area of California.
Natural gas and water services are provided in the Reno-Sparks area of Nevada.
Other segment information includes segments below the quantitative threshold for
separate disclosure.

     Information as to the operations of the different business segments is set
forth below based on the nature of products and services offered.  The Company
evaluates performance based on several factors, of which the primary financial
measure is business segment operating income.  Intersegment revenues are not
material.

     Based on a merger date of August 1, 1999, the segmented financial
information for the three and nine months ended September 30, 1999 include two
months (August and September 1999) of operating activity for the Company and its
subsidiaries other than NVP.  Segmented information for 1998 includes only the
operating results of NVP.

NOTE 9.   SUBSEQUENT EVENTS
- ---------------------------


     The Company and Enron Corporation announced that they entered into a
purchase and sale agreement for Enron's wholly owned electric utility
subsidiary, Portland General Electric (PGE).  PGE is an electric utility serving
more than 700,000 retail customers in northwest Oregon.  PGE will become a
wholly owned subsidiary of the Company.  Under terms of the agreement, Enron
will sell PGE to the Company for $2.1 billion, comprised of $2.02 billion in
cash and the assumption of Enron's approximately $80 million merger payment
obligation.  The Company will also assume $1.0 billion in PGE debt and preferred
stock.  At closing, the transaction will be financed through a bank loan.
Ultimately, the transaction will be financed with the proceeds from the sale of
the Company's Nevada generation assets (expected on or before the close of the
transaction) and the issuance of debt, equity and internal cash flow.

     The proposed transaction is subject to customary closing conditions,
including, without limitation, the receipt of all necessary governmental
approvals, including the Federal Energy Regulatory Commission, the Securities
and Exchange Commission (SEC), the Oregon Public Utility Commission and the
Nuclear Regulatory Commission.  Also, the Company intends to register with the
SEC as a public utility holding company under the Public Utility Holding Company
Act, which requires the consent of the Public Utilities Commission of Nevada.
The transaction is not subject to shareholder approval by the Company or Enron
Corp.  Approvals are expected to be received by the second half of 2000.

     See the Form 8-K filed on November 12, 1999, for additional details related
to the terms of the proposed transaction and merger agreement.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF
          FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    The information in this Form 10-Q, or in the Form 10-Q of SPPC attached as
an Appendix, includes forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. These forward-looking
statements relate to anticipated financial performance, management's plans and
objectives for future operations, business prospects, outcome of regulatory
proceedings, market conditions and other matters.  Words such as "anticipate",
"believe", "estimate", "expect", "intend", "plan" and "objective", and other
similar expressions identify those statements which are forward-looking. These
statements are based on management's beliefs and assumptions and on information
currently available to management. Actual results could differ materially from
those contemplated by the forward-looking statements.  In addition to any
assumptions and other factors referred to specifically in connection with such
statements, factors that could cause the Company's, NVP's or SPPC's actual
results to differ materially from those contemplated in any forward-looking
statement include, among others, the following: (1) the pace and extent of the
ongoing restructuring of the electric and gas industries in Nevada and
California; (2) the outcome of regulatory and legislative proceedings and
operational changes related to industry restructuring; (3) the amount SPPC and
NVP are allowed to recover from their customers for certain costs which prove to
be uneconomic in the new competitive market; (4) the outcome of ongoing and
future regulatory proceedings; (5) management's ability to integrate the
operations of the Company, SPPC and NVP and to implement and realize anticipated
cost savings from the recent merger with NVP; (6) industrial, commercial and
residential growth in the service territory of SPPC and NVP; (7) fluctuations in
electric, gas and other commodity prices and the ability to manage such
fluctuations successfully; (8) changes in the capital markets and interest rates
affecting the ability to finance capital requirements; (9 the loss of any
significant customers; (10) the ability to lessen the risk of the impact of the
Year 2000 on internal and external computer and software systems; and (11) the
weather and other natural phenomena.  Other factors and assumptions not
identified above may also have been involved in deriving these forward-looking
statements, and the failure of those other assumptions to be realized, as well
as other factors, may also cause actual results to differ materially from those
projected.  The Company assumes no obligation to update forward-looking
statements to reflect actual results, changes in assumptions or changes in other
factors affecting forward-looking statements.

     Residential electric revenues increased for the three and nine months ended
September 30, 1999 due to a 6.0% increase in customers over the prior periods
and rate increases related to deferred energy accounting.  These increases for
three months were partially offset by lower use per customer due to milder
weather in 1999.

     Commercial electric revenues increased for the three and nine months ended
September 30, 1999 due to a 5.0% increase in customers over the prior periods
and rate increases related to deferred energy accounting.

     Industrial electric revenues increased for the three and nine months ended
September 30, 1999 due to a 7.0% increase in customers over the prior periods
and also rate increases related to deferred energy accounting.  Use per customer
also increased for the three and nine month periods due to the addition of
several large customers.

     Other electric revenues decreased for the three and nine months ended
September 30, 1999 due to the sale of emission credits and water rights in 1998.

</TABLE>

     Purchased power costs decreased for the three months ended September 30,
1999 due primarily to a $30.5 million change in the recovery of the capacity
portion of power contracts.  In 1998 the capacity cost was included in purchased
power expense, but in 1999 the cost has been deferred in compliance with an
order from the PUCN and therefore not reflected in purchase expense.  Costs were
also lower due to a $3.1 million adjustment related to Nevada electric utility
restructuring for the second quarter of 1999.  These decreases in cost were
partially offset by

                                       17
<PAGE>

an 18% increase in the volumes purchased due to increased customers and an
increase in the per unit cost of power after adjustment for the charge related
to capacity charges.

     Purchased power costs increased for the nine months ended September 30,
1999 due primarily to a 13% increase in the volumes purchased due to increased
customers and an increase in the per unit cost of power.  This increase in cost
was partially offset by a $38 million adjustment in 1999 related to accounting
for the capacity portion of power contracts previously discussed.

</TABLE>

     Fuel costs decreased for the three months ended September 30, 1999 due to
lower per unit costs for coal and natural gas and a 6% decrease in generation
volume because of lower load than anticipated.  NVP arranged for firm purchases
during the summer months and when the load was less than anticipated, NVP had to
reduce its own generation.

     Fuel costs decreased for the nine months ended September 30, 1999 due to
lower unit prices for coal and natural gas partially offset by a 5% increase in
volumes generated due to increased customers.

     Deferred energy cost recognition has increased for the three and nine
months ended September 30, 1999 to match deferred energy rate increases during
1999.  In 1998, NVP's fuel revenue was insufficient to cover the fuel expense
and the difference was deferred in balancing accounts.  Rate increases were
granted to increase the company's fuel recovery and in 1999 fuel revenue was
sufficient to cover fuel expense and to begin reducing the deferred fuel
balancing accounts.

     Total allowance for funds used during construction (AFUDC) is lower for the
three and nine months ended September 30, 1999 because of construction completed
in May 1999 for the Crystal Transmission Project.  Lower AFUDC for the nine
month period was partially offset by a $1.6 million charge in 1998 for
Industrial Development Bonds held in trust that was deducted from the allowance
for borrowed funds used during construction.

</TABLE>

     Other operating expense was higher for the three months ended September 30,
1999 due to incentive plan payments made totaling $5.1 million. Other operating
expense was higher for the nine months ended September 30, 1999 due to incentive
plan payments of $5.1 million plus an increase in Pension and Benefit expense of
$4.0 million.

     Maintenance costs for the three months ended September 30, 1999 were
comparable with prior year amounts.  Maintenance costs were higher for the nine
months ended September 30, 1999 due to increased maintenance expense at the Reid
Gardner generating facility.

     Depreciation and amortization expense increased for the three months and
the nine months ended September 30, 1999, due to a growing asset base and the
completion of the Crystal Transmission Project. This project was completed in
May 1999 at a cost of $99.0 million.

     Interest charges on long-term debt increased for the three and nine months
ended September 30, 1999 due to interest costs on $130.0 million unsecured notes
issued in March 1999.  Also, in 1998 there was interest income of $1.4 million
from Industrial Development Bonds held in trust.

     Interest charges-other, was lower for the three months ended September 30,
1999, because of interest expense on short-term debt decreased by $1.0 million.
Interest charges-other increased $0.5 million for the nine months ended
September 30, 1999, due to increased expense for short-term notes.


              FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES
              ----------------------------------------------------

    During the first nine months of 1999, the Company earned $81.9 million in
income before preferred dividends and declared $57 million in common stock
dividends.  SPPC and NVP, the Company's principal subsidiaries, declared $4.1
million and $95 thousand in preferred stock dividends, respectively.

     Cash flows during the nine months ended September 30, 1999 increased
compared to the same period in 1998.  Cash flows were greater in 1999 due to
greater cash provided from financing activities.  The increase in cash provided
from financing activities was partially offset by less cash provided from
operating activities and greater cash utilized for investing activities.
Increased cash provided by financing activities resulted from the issuance of
$456.2 million of commercial paper to provide temporary funding of the cash
portion of the merger consideration.  Also, NVP issued long-term debt of $130
million 6.2% Series A senior unsecured notes, due 2004 and SPPC issued $100
million floating rate notes during the nine months ended September 30, 1999.
Cash utilized for Investing activities increased primarily as a result of the
merger cash requirements.  See Note 2 to the condensed consolidated financial
statements included in this quarterly report for more information about the
merger cash requirements. The decrease in cash provided by operating activities
was primarily due to increased operations, maintenance and interest costs.

Construction Expenditures and Financing
- ---------------------------------------

    A description of construction expenditures and financing of SPPC is
contained in its Quarterly Report Form 10-Q for the period ended September 30,
1999, attached as an appendix.

    NVP's construction program and capital requirements for 1999 and 2000 were
originally discussed in the NVP 1998 annual report on Form 10-K.  Of the amount
projected for 1999 ($245 million), $185 million (75.5%) was spent as of
September 30, 1999.  Internally generated funds equaled 39.6% of all
construction expenditures.

    NVP may utilize internally generated cash and the proceeds from unsecured
borrowings and preferred securities to meet capital expenditure requirements
through 1999.

     On July 28, 1999, immediately following the consummation of the merger with
NVP, the Company put into place a $500 million unsecured revolving credit
facility.  This facility may be used for working capital and general corporate
purposes, including for commercial paper backup, and replaced the Company's
existing credit facility.  At the same time, SPPC and NVP each put into place
$150 million unsecured revolving credit facilities.  These two facilities may
also be used for working capital and general corporate purposes, including for
commercial paper backup, and replaced all existing credit facilities for those
companies.  In addition, immediately following the merger, the Company and NVP
established new commercial paper programs, SPPC revised its existing commercial
paper program, and the Company issued $456.2 million of commercial paper to
provide temporary funding of the cash portion of the merger consideration.

     On October 1, 1999, NVP redeemed $45,000,000  Series Y, 6.93%, in long-term
debt.

     On October 15, 1999, NVP issued $100 million floating rate notes, Due
October 6, 2000.  Interest on the notes is payable quarterly in arrears
commencing on January 15, 2000.  The interest rate on the notes for each
interest period to maturity will be a floating rate, subject to adjustment every
three months, equal to the London Interbank Offered Rate for three month U.S.
dollar deposits (LIBOR) plus a spread of 0.79%.  These notes will not be
entitled to any sinking fund and will be redeemable at the option of NVP, in
whole, beginning on April 15, 2000 and on the 15th day of each month thereafter.
The proceeds of this financing will be used to pay down commercial paper.

Regulatory Matters
- ------------------

     Substantially all of the utility operations of both NVP and SPPC are
conducted in Nevada.  As a result both companies are subject to utility
regulation within the State and therefore deal with many of the same regulatory
issues. Therefore, although the following regulatory discussion relates
specifically to NVP, many of the same issues are discussed in the regulatory
section of the current SPPC Form 10-Q, attached as an appendix


                                 Nevada Matters
                                 --------------

Deferred Energy
- ---------------

     In its second quarter 1999 Form 10-Q NVP reported that it discontinued the
use of the deferred energy mechanism to defer the difference between the current
cost of fuel and purchased power and base energy costs, beginning in June 1999.
Subsequently, through the hearing process in its annual deferred energy case
which was filed on July, 1999, NVP learned that, as a matter of law, it could
not terminate deferred accounting without a prior Commission order authorizing
it to do so. Therefore, on September 30, 1999 NVP made a filing to replace its
original annual filing in which it recognized the reinstatement of deferred
energy accounting until the Commission issues an order authorizing termination.
The results of operations and the financial position reflect the use of deferral
accounting including the effects of June 1999 activity.

     On September 30, 1999, NVP filed with the PUCN an update of the deferred
energy accounting case filed in July 1999, which reflected costs for the year
ended May 31, 1999.  The updated filing reflects NVP's fuel and purchased power
costs through August 31, 1999.  Under traditional rate making rules, the
Company's rates could be designed to recover an increase in revenues of  $110.7
million during the first year.  NVP, however, has proposed an alternative that
would reduce its request by approximately 50 percent, to $50.6 million, by
spreading the increase over a three-year period.  The July 1999 filing requested
a $44.3 million increase.

     On January 12, 1999 and February 26, 1999, the PUCN issued orders on NVP's
1997 and 1998 deferred energy filings requiring NVP to establish a new deferral
account for a portion of purchase power expense, delayed recovery thereof to a
future filing, and denied carrying charges thereon.  On April 7, 1999 and May
27, 1999, NVP filed Petitions for Judicial Review of these PUCN orders with the
First District Court in Carson City, Nevada. At September 30, 1999, the amount
in the new deferral account totaled $54.3 million.  NVP's pending deferred
energy filings with the PUCN reflect recovery of the costs recorded in the new
deferred account. NVP can not determine the outcome of this matter at this time.

Affiliate Transaction Rules and Affiliate Applications to Provide Potentially
- -----------------------------------------------------------------------------
Competitive Services
- --------------------

     NVP and SPPC filed a joint motion to set aside or modify the affiliate
transaction rules adopted by the PUCN on January 14, 1999.  The companies
requested the PUCN to modify the rules related to name/logo, sharing services,
sharing officers and directors, and transfer pricing.  To date the PUCN has not
acted on this motion.  On March 30, 1999 NVP and SPPC filed with the District
Court a "Complaint and Petition for Declaratory and Injunctive Relief and for
Judicial Review" relating to the Affiliate Transaction Rules.  The companies
asked that the court find that the rules "violate plaintiff's federal and state
constitutional guarantees, are unlawful and invalid because they were enacted in
violation of the procedural and substantive provisions of the Administrative
Procedures Act, and are unlawful and invalid because they exceed the authority
of the PUCN and are unsupported by the evidence."  The companies asked that the
court order the PUCN "to cease and desist from enforcing the regulations."
There has been no action in the court case.

     The PUCN issued an order consolidating the merging companies' applications
for authorization to provide potentially competitive services, and hearings were
held June 28-30,1999.  On August 31, 1999, the PUCN issued an order denying the
companies' application.  On September 15, 1999, the companies filed a Petition
for Reconsideration of the PUCN's order denying the application.

Electric Restructuring Activities
- ---------------------------------

     In July 1997, the Governor of Nevada signed into law Assembly Bill 366
(AB366) which provides for competition to be implemented in the electric utility
industry in the state no later than December 31, 1999. However, in early
February 1999, the PUCN recommended to the state legislature that the start date
for competition be delayed to allow more time for consideration of issues as a
result of restructuring.  On April 19, 1999, the Nevada Senate passed SB438,
which is an amendment to AB366.  In July 1999 the Governor of Nevada signed
SB438 into law.   The new law contains the following provisions:

 .  Adds metering and billing as potentially competitive services.
 .  Changes start date for competition to March 1, 2000; any decision to further
   delay the start date to be made by the governor, not the PUCN.
 .  Electric distribution utility is the Provider of Last Resort (PLR) until
   alternate methods go into effect.
 .  Sets PLR rates at existing rates, except that Nevada Power may submit one
   more deferred energy case before October 1, 1999;  PLR may reduce rates below
   this level.
 .  Only the PLR may request a reduction in its rates during the period March 1,
   2000 through March 1, 2003.
 .  Allows the use of the net proceeds of generation divestiture to pay for any
   reduction in PLR rates below the cap described above, during the period March
   1, 2000 to March 1, 2003.
 .  Repeals deferred energy for electric operations October 1, 1999.
 .  Permits alternative sellers to submit bids to provide PLR service after July
   1, 2001, subject to a PUCN public interest finding and a PUCN-held auction.
 .  Requires utilities to comply with terms of existing purchase power
   obligations; specifies criteria for recovery of purchase power costs;
   prevents PUCN from direct or indirect action to modify or terminate any
   purchase power obligation.
 .  If utility purchases generation from a divested unit for PLR service the PUCN
   cannot impute a value of the generation unit other than the sales price of
   the unit.
 .  PUCN must consider in determining recoverable costs, the failure of a utility
   to minimize income tax effect of gains and losses of assets and obligations.
 .  PUCN must include in recoverable costs any reasonable costs incurred by the
   utility for severance, early retirement, and related items.
 .  Allows affiliates providing potentially competitive services to use name and
   logo of utility.
 .  SB 438 does not impair rights under existing electric service contracts or
   labor agreements.
 .  Utilities may enter into contracts with customers prior to March 1, 2000;
   specifies that alternative sellers may aggregate two or more customers;
   prohibits PUCN from limiting ability of alternative sellers to aggregate
   customers and for customers to form groups for aggregation.
 .  Allows the PUCN to use "hearing officers" to conduct hearings.

     During the hearing on the proposed past cost rule on June 1, 1999, the PUCN
determined that the impacts of SB 438 on existing and proposed electric
restructuring regulations should be evaluated.  The PUCN issued Procedural
Orders 13 and 14 and held workshops to discuss the impact of SB 438.

     See the Company's and NVP's 1998 Annual Reports on Form 10-K for more
information regarding the issues being considered as a result of restructuring
of the electric industry in Nevada.  The following are highlights of recent
restructuring activity:

     Compliance Plan

     On April 1, 1999, NVP filed with the PUCN the initial compliance filing
required for rate restructuring to reflect competition.  On September 27, 1999,
the PUCN issued an Interim Order on that compliance filing.  The

                                       22
<PAGE>

interim Order contains the PUCN's determinations of Nevada Power's gross annual
revenue requirement, required rate of return and return on equity, depreciation
rates, and the unbundling study used to allocate costs among various functional
categories (e.g., generation, transmission, distribution). NVP believes that SB
438 established the current revenue requirement for the vertically integrated
electric utility as present rate revenues. However, the interim Order denies
NVP's motion to limit the scope of proceedings in light of SB 438. On October
12, 1999, NVP filed with the PUCN a Petition for Reconsideration of the Interim
Order and proposed tariff for distribution service.

Distribution Open Access Tariffs

     On January 7, 1999, the PUCN issued an order adopting a final rule for
distribution tariffs (adopted as a temporary regulation).  On February 1, 1999
SPPC filed proposed language for distribution tariffs and filed testimony in
support of its distribution tariffs filing on March 9, 1999.  On April 9, 1999 a
stipulation resolving most issues and agreeing to further filings on unresolved
issues was filed with the PUCN.

     NVP and SPPC conducted informal workshops with the appropriate parties to
resolve issues related to Rules 9 (Line Extensions) and 15 (Non-Utility
Generation Facilities) of the Distribution Open Access Tariffs. Rule 9 provides
for competition in line extension designs and construction while Rule 15
provides procedures for the connection of non-utility generators. A settlement
was reached resolving Rule 15 and filed with the PUCN on June 18, 1999.  Another
settlement was reached resolving Rule 9 and was filed with the PUCN on July 9th.

Past Costs
- ----------

     Past costs, which are commonly referred to as stranded costs in other
jurisdictions, continue to be addressed in 1999.  AB366 permits the recovery of
generation costs pursuant to specified legal criteria.  The PUCN has conducted
several workshops on past costs in which various topics were discussed,
including the characteristics that define recoverable past costs, criteria for
evaluating the effectiveness of mitigation efforts, options for cost recovery
mechanisms and applicable tax and accounting issues.

     On April 8, 1999, the PUCN issued a revised proposed rule that specifies
the information a utility must include in its request for recovery of past
costs.  The final rule is expected to include the date for the submission of
filings to recover past costs, which will likely be 45 days after the order from
the compliance plan filing is issued.

     On June 1, 1999, the PUCN began and suspended the hearing on the proposed
past cost rule.  Due to the passage of SB 438, the PUCN determined that this
rule and other regulations should be evaluated to investigate the impact of SB
438 has on this and other pending and adopted regulations.  The PUCN has
scheduled a hearing on November 8, 1999, on the proposed past cost rule.  NVP
has not completed an estimate of its past costs, since such a calculation is
dependent on a variety of issues related to restructuring which are not resolved
at this time.  These rules are expected to be completed and any required past
cost filing will be made late in 1999 or early 2000.

Provider of Last Resort
- -----------------------

     The provider of last resort (PLR) will provide electric service to
customers who do not select an electricity provider and to customers who are not
able to obtain service from an alternative seller after the date competition
begins.  On March 16, 1999 the PUCN issued a revised proposed rule for PLR.  A
hearing was held April 26, 1999.  A new procedural final order was issued
regarding those matters.

     The PUCN proposed PLR format requires the PLR functions to be performed by
a regulated affiliate of NVP and not by the electric distribution utility.  The
business activities of the PLR affiliate must be limited to the PLR function.
NVP and SPPC filed joint comments which outlined concerns that the PUCN proposed
PLR format would not be financially viable.  The PUCN issued Procedural Order 11
to request comments on the financial viability of the PUCN proposed PLR format.

                                       23
<PAGE>

     SB 438 specifically provides for the electric distribution utility to
provide PLR services until July 1, 2001.  The PUCN has scheduled a workshop on
November 8, 1999 on a new proposed rule for the PLR.

Independent Scheduling Administrator
- ------------------------------------

     NVP has participated in interim Independent Scheduling Administrator (iISA)
working groups which are developing iISA standards, protocols and procedures.
The PUCN issued a "Notice of Request for Comments and Notice of Workshop" to
hear from entities interested in performing the iISA function, the timeline, the
functions to be performed, the costs and how these entities will adhere to the
PUCN iISA principles.  The PUCN held a workshop on the proposed iISA on July 14,
1999.  Presentations were made by the Mountain West ISA and the California ISO.
The workshop was continued on July 22, 1999.

     On behalf of the Mountain West ISA, NVP and SPPC submitted a filing to
establish the ISA with the Federal Energy Regulatory Commission ("FERC") on July
23, 1999.  See "Regulatory Matters - FERC Matters - Independent Scheduling
Administrator (ISA)".  The PUCN held a workshop to discuss the adequacy of the
ISA proposal.

     On September 13, 1999, NVP and SPPC filed a brief on recovery of ISA
funding.  On September 17, 1999, the PUCN issued a Procedural Order setting the
schedule for a hearing on the ISA filing.  The PUCN identified two issues for
the hearing on October 25, 1999: ISA funding and pre-existing contracts.  The
PUCN also requested parties to file a list of additional issues.  NVP and SPPC
filed a response to the PUCN Procedural Order and testimony for the hearing.

Meter and Data Exchange
- -----------------------

     The PUCN issued a Notice of Tariff Filing and Notice of Hearing on meter
and data exchange standards and protocols on September 23, 1999.  The hearing
was held on October 27, 1999 and an order on the issue is pending.

FERC Matters
- ------------

Transmission Rate Case

     On May 29, 1999, Nevada Power filed a transmission rate case to reflect the
costs of the Crystal project and to incorporate the re-classification of
transmission and distribution facilities approved by the PUCN last summer. The
filing requests an increase of $ 18.6 million in the annual revenue requirement
for network service.  The point-to-point rate would increase from $ 1.26 / kW-
mo. to $ 1.41 / kW-mo.

     On September 16, 1999, as expected, the FERC issued an order setting the
rate case for hearing.   The proposed rates are accepted, subject to refund, and
suspended until March 1, 2000.  The FERC also approved NPC's proposed
Transmission / Distribution split.  On September 30, 1999 a pre-hearing
conference was held to set the procedural schedule.

Independent Scheduling Administrator (ISA)

     On July 23, 1999, NVP and SPPC submitted a filing to establish the Mountain
West ISA (Docket ER97-3719).  The proposal centers on the formation of an
interim ISA called Mountain West ISA, which will ensure the non-discriminatory
treatment of transmission customer in two wholesale electricity markets; one in
northern Nevada and one in southern Nevada.  The formation of the ISA is viewed
as an interim step in the move to broader regional restructuring of the electric
service industry in the western United States.

     Fifteen parties filed to intervene in the ISA filing.  On September 17,
1999, NVP, SPPC and the Mountain West ISA filed answers to the protests filed on
the ISA filing.  The California ISO filed an answer to the Company's and Nevada
Power's response to their protest on September 28, 1999.

Year 2000 Issues
- ----------------

     All significant computer systems of the Company are owned by NVP and SPPC.
A complete description of Year 2000 (Y2K) issues related to SPPC are contained
in its current Form 10-Q, attached as an appendix.  The following discussion
describes Y2K issues of NVP.

     The Company continues to make Y2K readiness a top priority for all of its
departments.  With the oversight of several officers, the Company has completed
its review of all mission critical computers, software programs and electrical
systems to verify that appropriate actions are being taken in order to be Y2K
ready, including the ability to process, calculate, compare and sequence date
data into the next century, and to make all necessary leap year corrections.

     A plan is in place and has been implemented to identify and correct
problems related to the Y2K issue and to test remediated systems, including
verification of the level of Y2K readiness of business partners and suppliers.
The responses of business partners and suppliers are evaluated individually and
responded to as appropriate.   A centralized data base is used to identify and
track the progress of Y2K readiness activities Company-wide.  A centralized
control over incoming correspondence and inquiries relating to Y2K and external
communication efforts is being maintained. The Company's general purchasing
policy requires that all newly purchased products be Y2K ready or designed to
allow the Company to determine whether such products present Y2K issues.

     The Company's Y2K readiness activities were tracked and reported monthly
through June 1999 to the North American Electric Reliability Council (NERC), an
association of all segments of the electric industry - investor-owned, federal,
state/municipal and provincial utilities, rural electric cooperatives,
independent power producers, and power marketers, with the general mission to
promote the reliability of the electricity supply for North America.

     Overall status for the Company as of September 30, 1999 shows
identification and assessment of potential problems at 100% complete and
remediation/testing at 99% complete. The Company filed its monthly report to the
North American Electric Reliability Council (NERC) on June 30, 1999 and provided
its "Y2K Readiness With Limited Exceptions" status letter, based on NERC
guidelines. A monthly exception report is provided to NERC until all remaining
items are completed.  All but one generation unit have been successfully
remediated and tested to date, with one unit generation unit to be remediated
and tested in October of 1999 to conform with the annual scheduled maintenance
outage.  This unit is similar to others in the Company's system which have been
remediated and tested and is not critical to the ability of the Company to
provide reliable service to customers during the Y2K rollover.  No material
difficulties have been identified to date and none are anticipated.

     Even though the Company is confident that its critical systems have been
fully remediated and tested, the Company has initiated a corporate-wide process
of Y2K contingency planning.  Contingency planning has been influenced by the
responses received from business partners and suppliers received in upcoming
months, as well as the Company's determination of a reasonably worst case
scenario.  The contingency plan has been finalized and tested.  The Company is
also working with utility and non-utility suppliers, generation and transmission
operators and regional governmental organizations to develop external
contingency plans, where appropriate. The reasonably worst case scenario
anticipated would be loss of standard means of communication.  This has been
addressed in contingency planning.  Nevada Power Company is confident that the
steps taken to deal with this scenario, which include the use of several
alternative means of communication such as two-way radio and internal microwave
and fiber optic systems, will provide sufficient backup in the unlikely event of
the loss of standard communication.  As a summer peaking utility, the Company's
electrical loads in mid-winter are comparatively low.  Although contingency
planning is by its nature speculative, the Y2K contingency plan will reduce the
risk of material impacts on the Company's operations due to Y2K problems.  If
the Company or its significant business partners or suppliers were to fail to
achieve Y2K readiness with respect to critical systems, there could be a
materially adverse impact on the utility's financial position, results of
operations and cash flows.

     During 1998, the estimated total cumulative cost to the Company of
addressing Y2K readiness was determined to be in the range of $4 to $7 million,
including operating and capital expenditures.  Through

                                       25
<PAGE>

September 1999, approximately $2.9 million in operating expenses and
approximately $1.5 million in capital additions have been incurred. While
additional expenditures and capital additions will be incurred throughout 1999,
the rate of expenditures and capital additions is below original estimates. The
estimated total cumulative cost is reviewed and revised periodically.


ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES
          ABOUT MARKET RISK

     There have been no material changes to the information previously disclosed
regarding quantitative and qualitative market risk in the Company's and NVP's
Annual Reports for on Form 10K for the year ended December 31, 1998.

ITEM 1.   LEGAL PROCEEDINGS

    Although the Company is involved in ongoing litigation on a variety of
matters, it is management's opinion that none individually or collectively are
material to the Company's financial position.

    With respect to NVP, see the discussion of pending litigation set forth in
Note 6 of the Notes to the Consolidated Financial Statements included in this
report.

ITEM 5.   OTHER INFORMATION

Portland General Electric Merger
- --------------------------------

     The Company and Enron Corporation announced that they entered into a
purchase and sale agreement for Enron's wholly owned electric utility
subsidiary, Portland General Electric (PGE).  PGE is an electric utility serving
more than 700,000 retail customers in northwest Oregon.  PGE will become a
wholly owned subsidiary of the Company.  Under terms of the agreement, Enron
will sell PGE to the Company for $2.1 billion, comprised of $2.02 billion in
cash and the assumption of Enron's approximately $80 million merger payment
obligation.  The Company will also assume $1.0 billion in PGE debt and preferred
stock.  At closing, the transaction will be financed through a bank loan.
Ultimately, the transaction will be financed with the proceeds from the sale of
the Company's Nevada generation assets (expected on or before the close of the
transaction) and the issuance of debt, equity and internal cash flow.

     The proposed transaction is subject to customary closing conditions,
including, without limitation, the receipt of all necessary governmental
approvals, including the Federal Energy Regulatory Commission, the Securities
and Exchange Commission (SEC), the Oregon Public Utility Commission and the
Nuclear Regulatory Commission.  Also, the Company intends to register with the
SEC as a public utility holding company under the Public Utility Holding Company
Act, which requires the consent of the Public Utilities Commission of Nevada.
The transaction is not subject to shareholder approval by the Company or Enron
Corp.  Approvals are expected to be received by the second half of 2000.

     See the Form 8-K for additional details related to the terms of the
proposed transaction and merger agreement.

             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
             ----------------------------------------------------


NOTE 1.   MANAGEMENT'S STATEMENT
- --------------------------------

         In the opinion of the management of Sierra Pacific Power Company,
hereafter referred to as the Company, the accompanying unaudited interim
condensed consolidated financial statements contain all adjustments (consisting
of only normal recurring adjustments) necessary to present fairly the condensed
consolidated financial position, condensed consolidated results of operations
and condensed consolidated cash flows for the periods shown. These condensed
consolidated financial statements do not contain the complete detail or footnote
disclosure concerning accounting policies and other matters which are included
in full year financial statements and therefore, they should be read in
conjunction with the Company's audited financial statements included in the
Company's Annual Report on Form 10-K for the year ended December 31, 1998.

         The results of operations for the three and nine month period ended
September 30, 1999 are not necessarily indicative of the results to be expected
for the full year.

                          Principles of Consolidation
                          ---------------------------

         The consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiaries, Sierra Pacific Power Capital I, Pinon
Pine Corp., and Pinon Pine Investment Co. The Company accounts for its ownership
of GPSF-B, a Delaware corporation acquired in February 1999, using the equity
method because the Company intends to own the entity temporarily. All
significant intercompany transactions and balances have been eliminated in
consolidation.

                               Reclassifications
                               -----------------

          Certain items previously reported for years prior to 1999 have been
reclassified to conform to the current year's presentation. Net income and
shareholder's equity were not affected by these reclassifications.


NOTE 2.   RECENT PRONOUNCEMENTS OF THE FASB
- -------------------------------------------

         In June 1998, the Financial Accounting Standards Board issued SFAS 133,
entitled "Accounting for Derivative Instruments and Hedging Activities". This
statement establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts (collectively referred to as derivatives), and for hedging activities.
It requires an entity to recognize all derivatives as either assets or
liabilities in the statement of financial position, and measure those
instruments at fair value. In May 1999, members of the Financial Accounting
Standards Board agreed to delay the effective date of Statement 133 to fiscal
years beginning after June 15, 2000. The Company is still assessing the impact
of SFAS 133 on its financial condition and results of operations.


NOTE 3.   LONG TERM DEBT
- ------------------------

         On July 12, 1999, $10 million of the Company's 6.86% medium term notes
matured. On July 16, 1999, $20 million of the Company's 6.83% medium term notes
matured.

         On September 17, 1999, the Company issued $100,000,000 Floating Rate
Notes, due October 13, 2000. Interest on the Notes is payable quarterly in
arrears commencing on December 15, 1999. The interest rate on the Notes for each
interest period to maturity will be a floating rate, subject to adjustment every
three months, equal to the London InterBank Offered Rate for three-month U.S.
dollar deposits ("LIBOR") plus a spread of 0.75%. These Notes will not be
entitled to any sinking fund and will be redeemable without premium at the
option of the Company, in whole, beginning on March 15, 2000 and on the 15th day
of each month thereafter.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

      The information in this Form 10-Q includes forward-looking statements
      within the meaning of the Private Securities Litigation Reform Act of
      1995. These forward-looking statements relate to anticipated financial
      performance, management's plans and objectives for future operations,
      business prospects, outcome of regulatory proceedings, market conditions
      and other matters. Words such as "anticipate," "believe," "estimate,"
      "expect," "intend," "plan" and "objective," and other similar expressions
      identify those statements which are forward-looking. These statements are
      based on management's beliefs and assumptions and on information currently
      available to management. Actual results could differ materially from those
      contemplated by the forward-looking statements. In addition to any
      assumptions and other factors referred to specifically in connection with
      such statements, factors that could cause the Company's actual results to
      differ materially from those contemplated in any forward-looking statement
      include, among others, the following: (1) the pace and extent of the
      ongoing restructuring of the electric and gas industries in Nevada and
      California; (2) the outcome of regulatory and legislative proceedings and
      operational changes related to industry restructuring; (3) the amount the
      Company is allowed to recover from its customers for certain costs which
      prove to be uneconomic in the new competitive market; (4) the outcome of
      ongoing and future regulatory proceedings; (5) management's ability to
      integrate the operations of the Company and Nevada Power Company and to
      implement and realize anticipated cost savings from the recent merger with
      Nevada Power; (6) industrial, commercial and residential growth in the
      service territory of the Company; (7) fluctuations in electric, gas and
      other commodity prices and the ability to manage such fluctuations
      successfully; (8) changes in the capital markets and interest rates
      affecting the ability to finance capital requirements; (9) the loss of any
      significant customers; (10) the ability to lessen the risk of the impact
      of the Year 2000 on internal and external computer and software systems;
      and (11) the weather and other natural phenomena. Other factors and
      assumptions not identified above may also have been involved in deriving
      these forward-looking statements, and the failure of those other
      assumptions to be realized, as well as other factors, may also cause
      actual results to differ materially from those projected. The Company
      assumes no obligation to update forward-looking statements to reflect
      actual results, changes in assumptions or changes in other factors
      affecting forward-looking statements.

     Residential electric revenues increased for the three and nine months ended
September 30, 1999 due to a 2.7% increase in total customers over the prior
periods. The increase in revenues due to customer growth was almost entirely
offset by lower use per customer due to cooler weather for the three months
ended September 30, 1999.

     Commercial electric revenues increased for the third quarter of this year
compared with the third quarter of 1998 due to a 3.0% increase in total
customers. Commercial revenues increased for the nine months ended September 30,
1999, due to a 3.1% increase in total customers and higher average use per
customer. Higher average use per customer resulted from the addition of larger
customers included in the commercial classification

     Industrial electric revenues decreased slightly for the third quarter
compared to the prior year primarily due to lower use per customer for several
of the Company's gold mining customers. Industrial revenues increased for the
nine months ended September 30, 1999 due to customer growth that was partially
offset by lower use per customer. The reduction in use per customer for both
periods was the result of reduced production at several of the Company's gold
mining customers' facilities as a result of lower gold prices.

     As reported in the Company's 1998 10-K, gold production costs vary greatly
at Nevada mines, along with profitability. Mining reports indicate many of
Nevada's mines have a production cost of less than $300 per ounce, with some
larger mines producing within the $192 to $240 per ounce range. When compared to
world production costs, Nevada is well below the worldwide average of $262 per
ounce. While Nevada's gold mines have the lowest costs in the world, investments
in exploration and development have fallen, and may continue to fall. In
addition, low gold prices may also shorten the expected mine lives of certain
Nevada properties as lower grade ore becomes uneconomic to mine.

     Other electric revenues were higher in the third quarter of 1999 compared
to the prior year primarily due to a $8.7 million increase in wholesale electric
revenues. This increase was partially offset by a higher provision for customer
refunds during 1999. Other electric revenues were higher for the nine months
ended September 30, 1999 due to a $16.5 million increase in wholesale electric
sales. This increase was partially offset by a $4.3 million reclassification
from operating expense to a contra-revenue in order to reflect a refund
resulting from the 1997 earnings sharing decision by the Public Utilities
Commission of Nevada. Also, the increase in 1999 revenues was partially offset
by a higher provision for customer refunds and losses from the Company's Pinon
Pine subsidiaries.

</TABLE>

     Residential gas revenues were higher for the three and nine months ended
September 30, 1999 due to 4.4% and 4.2% increases in customers, respectively.
Revenues were also higher for the third quarter of 1999 because of higher use
per customer.

     Commercial gas revenues for the three and nine months ended September 30,
1999 were comparable with the same periods in 1998. In both current year periods
presented, increased revenues from customer growth was offset by lower use per
customer. The lower use per customer for the nine months ended September 30,
1999 was the result of warmer weather during the first part of the year when gas
is used to heat.

     Industrial gas revenues were lower for the three and nine months ended
September 30, 1998 due to lower use per customer as a result of warmer weather
early in 1999.

     Wholesale gas revenues for the third quarter of 1999 were comparable with
the prior year. Wholesale revenues were higher for the nine months ended
September 30, 1999 due to several large gas sales contracts during the first
quarter of 1999.

     Water revenues were higher for the third quarter of 1999 due mostly to a
5.9% increase in total customers. Water revenues increased for the nine months
ended September 30, 1999 compared to the prior year primarily due to a 4.4%
increase in total customers and higher use per customer as a result of less
precipitation during 1999.

</TABLE>

     Purchased power costs were higher for the three and nine months ended
September 30, 1999 because the Company fulfilled more of its total energy
requirements with less expensive purchased power and reduced its own generation.
Purchased power costs were also higher during 1999 due to increased wholesale
sales. The higher costs were partially offset by lower average unit prices for
purchased power.

     Fuel for generation costs for the three and nine months ended September 30,
1999, were comparable with the prior year despite 14.5% and 9.1% reductions in
electric generation, respectively. Higher gas prices and the absence of
Department of Energy co-funding of fuel costs at the Pinon Pine project
contributed to the higher average cost per MWH

of generated power. As discussed above, the Company was able to replace
electricity from generation with less expensive purchased power.

     The cost of retail gas purchased for resale increased for the three and
nine months ended September 30, 1999 because of considerably higher gas unit
prices. The increase in gas unit prices is attributable to increased demand for
gas in the Pacific Northwest and additional transportation fees.

     Total allowance for funds used during construction (AFUDC) is lower for the
three and nine months ended September 30, 1999 because of construction completed
in June and December 1998 for the Pinon and Alturas projects, respectively.
Also, the 1999 amounts reflect an adjustment to reverse amounts previously
charged to AFUDC of $4.5 million. This adjustment resulted from a refinement of
amounts assigned to specific components of facilities that were completed in
different periods and used differing AFUDC rates.

</TABLE>

     Other operating expense was higher for the third quarter of 1999 due to
higher claims reserves during the current year and adjustments that reduced
costs during 1998 related to stock compensation. Other operating expense was
slightly lower for the nine months ended September 30, 1999 due to a
reclassification of $4.3 million from expense to a contra-revenue in order to
reflect a refund resulting from the 1997 earnings sharing decision by the Public
Utilities Commission of Nevada. The decrease in costs for 1999 was partially
offset by higher claims reserves, rate case adjustments and other miscellaneous
items expensed during the current year.

     Maintenance costs were higher for the three and nine months ended September
30, 1999 due to scheduled maintenance costs at the Valmy Unit 2 generating
facility.

     Depreciation and amortization expense increased for the three months ended
September 30, 1999, due to the completion of the Alturas intertie in December
1998. Depreciation and amortization expense increased for the nine months ended
September 30, 1999, due to the completion of the Alturas intertie in December
1998 and the Pinon post-gasification facilities in June 1998.

     Operating income taxes decreased for the three and nine months ended
September 30, 1999 due to lower operating income before income taxes and a lower
effective tax rate during the current year.

     Interest charges-other were higher for the three and nine months ended
September 30, 1999, because of a Public Utilities Commission of Nevada's
decision to assess partial interest on amounts payable in the 1997 earnings
sharing case and higher average short-term borrowing in 1999.


             FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES
             ----------------------------------------------------

     During the first nine months of 1999, the Company earned $53.2 million in
income before preferred dividends. It declared $4.1 million in dividends to
holders of its preferred stock and declared $57.0 million in common stock
dividends to its parent, Sierra Pacific Resources.

     Cash flows during the nine months ended September 30, 1999 decreased
slightly compared to the same period in 1998. Cash flows were less in 1999 due
to less cash provided from operating activities and more cash used for investing
activities. The decrease in cash flows from operating and investing activities
was partially offset by cash provided from financing activities. The decrease in
cash provided from operating activities was primarily due to cash utilized for
customer refunds and merger related cash requirements. The increase in cash used
for investing activities was due to the Company's acquisition of General
Electric Capital Corporation's interest in Pinon Pine Company L.L.C., GPSF-B.
Net cash provided by financing activities resulted from the issuance of $24
million of California rate reductions bonds in April 1999 and $100 million
floating rate notes issued on September 17, 1999. See "Regulatory Matters" for
more details regarding the California bonds.

Construction Expenditures and Financing
- ---------------------------------------

     The Company's construction program and capital requirements for the period
1999-2003 were originally discussed in the Company's 1998 Annual Report on Form
10-K. Of the amount projected for 1999 ($112.7 million), $78.9 million (70.0%)
was spent as of September 30, 1999. Internally-generated funds provided 57.7% of
all construction expenditures.

     On July 28, 1999, immediately following the consummation of the merger
between the Company's parent, Sierra Pacific Resources "SPR" and Nevada Power
Company, the Company put into place a $150 million unsecured revolving credit
facility with Mellon Bank, N.A., as Administrative Agent, First Union National
Bank and Wells Fargo Bank, N.A., as Syndication Agents, and certain other
participating banks. This facility may be used for working capital and general
corporate purposes, including for commercial paper backup, and replaced all
existing credit facilities of the Company.

     On October 1, 1999 Sierra Pacific Power Company provided Notice of
Redemption to the holders of Preferred Stock, Series A, $2.44 Dividend (4.88%),
Series B, $2.36 Dividend (4.72%) and Series C, $3.90 Dividend (7.80%). The
company paid $23.8 million on November 1, 1999 to effect the redemption. The
amount paid included the preferred stock par value of $23.1 million, a call
premium of $.4 million and accrued dividends of $.3 million.

Pinon Pine Power Project
- ------------------------

     As reported in the Company's 1998 Annual Report on Form 10K, the Company
has been in dispute with the DOE concerning funding of the remaining $14 million
under the cooperative agreement and the allowance of previously incurred natural
gas fuel cost paid by the DOE. On November 2, 1999 the Company reached final
agreement with the DOE regarding the allowability of previously incurred natural
gas costs. The agreement also redefines the cooperative agreement performance
period and the responsibilities of both parties through the remainder of the
agreement. The period of performance is extended until January 1, 2001 or until
the facility is sold or operational control is transferred. The DOE agrees to
share past fuel costs and future natural gas costs used to fuel the gas
combustion turbine during periods when air extraction from the process is
directed to the gasifier island. In the agreement, the Company agreed to
undertake reasonable efforts to make the gasifier operational that include
capital improvements of $3.8 million, half of which will be funded by the DOE,
and a commitment to provide a defined level of operating expenses and other
engineering resources.

     The Company is continuing in its efforts to obtain sustained operation of
the gasifier by identifying and redesigning problem areas.

Merger
- ------

     On July 28, 1999 the merger between SPR and Nevada Power Company was
finalized.

     On June 11, 1999, following approvals from the Department of Justice (April
16, 1999) and the SEC (expiration of comment period on June 8, 1999), the PUCN
gave unanimous approval of a stipulation between the merging companies, PUCN
staff and the Utility Consumer Advocate, regarding the merging companies' joint
divestiture plan. As part of the stipulation, the companies were required to
re-file the divestiture plan and file the final Independent System Administrator
(ISA) proposal with the PUCN and the Federal Energy Regulatory Commission
(FERC). The last filing was submitted in October 1999. The PUCN merger order
provides that upon selling the generating units, both companies can determine
how they will use the proceeds of the sales, up to the book value of the plants.
Any after-tax gains above book value will be used to offset stranded costs, as
determined by the PUCN. The PUCN order also provided that any remaining gains
can be used to offset goodwill. After-tax gains may not be sufficient to offset
goodwill. However, if the combined Company demonstrates that the divestiture
"resulted in a market for generation services that produced market prices that
are lower than what could have been achieved otherwise, the combined Company may
include in the general rate a request to recover goodwill." The Company expects
that most of the generation facility sales will be completed by late-2000.

     Following the issuance of the PUCN order on the merger, the Nevada
Legislature passed SB 438 which amended the restructuring process in Nevada.
Among other provisions, it required the utilities to provide last resort service
at a capped price, and provided that any shortfall experienced by the utilities
in revenues from the capped rates over experienced costs could be recovered from
the net gain from the generation divestiture. It is the utilities' position that
any

                                       14
<PAGE>

net gain must first be applied to any such shortfall; any remaining net gain may
then be used to offset stranded costs and then allocated to goodwill.

         Under terms of the stipulation, the merged company is required to file
a general rate case three years after the start of retail competition in the
state of Nevada that would give the merged company the opportunity to recover
costs of the merger, provided the merged company can demonstrate that merger
savings exceed merger costs. Merger costs are to be split among the non-
competitive, potentially competitive and unregulated services or businesses. An
opportunity to recover the non-competitive portion of the merger costs will be
addressed in the rate case that follows the start of competition in Nevada. The
burden is on the merged company to prove that merger savings exceed merger
costs. The merged company will also have the opportunity to recover goodwill in
the same proceeding.

         Through September 30, 1999 the Company had incurred a total of $28.5
million in capitalized costs since merger work began. The capitalized amounts
consist of $17.3 million of transaction and transition costs and $11.2 million
of employee separation costs.

         ----------------------   ---------------------------------
Senate Bill 438, and its impact on the merged company and generation
divestiture.

Regulatory Matters
- ------------------

                                Nevada Matters
Earnings Sharing

         In February 1997, the PUCN approved a rate plan that provided for a
50/50 sharing between customers and Company shareholders of electric and gas
utility earnings in excess of a 12 percent return on average equity. In lieu of
refunds, the Company has an opportunity, subject to certain conditions, to apply
excess earnings toward buying out of long-term fuel and purchased power
contracts. The earnings sharing agreement applies to each of the three years
ending December 31, 1999, 1998 and 1997.

         On April 21, 1999, the PUCN approved refunds of $8.0 million in
electric and $1.5 in gas, plus interest, for the 1997 earnings sharing case. The
gas refund reflects the PUCN's acceptance of the Company's recommendation to
apply $0.4 million of the refund to offset the variable interest receivable
balance. The PUCN deferred its decision on several issues which could result in
an additional $1.5 million of refunds in the 1997 earnings sharing case. The
Company had originally requested to refund $7.3 million for electric and $1.7
million for gas. All amounts are provided for in the financial statements.

         On April 30, 1999, the Company filed an earnings sharing request, based
on 1998 earnings, of $7.0 million for electric customers and $1.9 million for
gas customers. On August 19, 1999, the PUCN approved a stipulation between the
Company, Staff, and the Utilities Consumer Advocate, which resulted in a $7.4
million and a $2.0 million refund to electric and gas customers, respectively.

Affiliate Transaction Rules and Affiliate Applications to Provide Potentially
Competitive Services

         The Company and Nevada Power Company filed a joint motion to set aside
or modify the affiliate transaction rules adopted by the PUCN on January 14,
1999. The Companies requested the PUCN to modify the rules related to name/logo,
sharing services, sharing officers and directors, and transfer pricing. To date
the PUCN has not acted on this motion. On March 30, 1999 the Company and Nevada
Power filed with the District Court a "Complaint and Petition for Declaratory
and Injunctive Relief and for Judicial Review" relating to the Affiliate
Transaction Rules. The companies asked that the court find that the rules
"violate plaintiff's federal and state constitutional guarantees, are unlawful
and invalid because they were enacted in violation of the procedural and
substantive provisions of the Administrative Procedures Act, and are unlawful
and invalid because they exceed the authority of the PUCN and are unsupported by
the evidence." The Companies asked that the court order the PUCN "to cease and
desist from enforcing the regulations." There has been no action in the court
case.

         The PUCN issued an order consolidating the merging Companies'
applications for authorization to provide potentially competitive services, and
hearings were held June 28-30,1999. On August 31, 1999, the PUCN issued an order
denying the Companies' application. On September 15, 1999, the Companies filed a
Petition for Reconsideration of the PUCN's order denying the application.

                                       15

Electric Restructuring Activities

         In July 1997, the Governor of Nevada signed into law Assembly Bill 366
(AB366) which provides for competition to be implemented in the electric utility
industry in the state no later than December 31, 1999. However, in early
February 1999, the PUCN recommended to the state legislature that the start date
for competition be delayed to allow more time for consideration of issues as a
result of restructuring. On April 19, 1999, the Nevada Senate passed SB438,
which is an amendment to AB366. In July 1999 the Governor of Nevada signed SB438
into law. The new law contains the following provisions:

 .  Adds metering and billing as potentially competitive services.

 .  Changes start date for competition to March 1, 2000; any decision to further
   delay the start date to be made by the governor, not the PUCN.

 .  Electric Distribution utility is the Provider of Last Resort (PLR) until
   alternate methods go into effect.

 .  Sets PLR rates at existing rates, except that Nevada Power may submit one
   more deferred energy case before October 1, 1999; PLR may reduce rates below
   this level.

 .  Only the PLR may request a reduction in its rates during the period March 1,
   2000 through March 1, 2003.

 .  Allows the use of the net proceeds of generation divestiture to pay for any
   reduction in PLR rates below the cap described above, during the period
   March 1, 2000 to March 1, 2003.

 .  Repeals deferred energy for electric operations October 1, 1999.

 .  Permits alternative sellers to submit bids to provide PLR service after
   July 1, 2001, subject to a PUCN public interest finding and a PUCN-held
   auction.

 .  Requires utilities to comply with terms of existing purchase power
   obligations; specifies criteria for recovery of purchase power costs;
   prevents PUCN from direct or indirect action to modify or terminate any
   purchase power obligation.

 .  If utility purchases generation from a divested unit for PLR service the PUCN
   cannot impute a value of the generation unit other than the sales price of
   the unit.

 .  PUCN must consider in determining recoverable costs, the failure of a utility
   to minimize income tax effect of gains and losses of assets and obligations.

 .  PUCN must include in recoverable costs any reasonable costs incurred by the
   utility for severance, early retirement, and related items.

 .  Allows affiliates providing potentially competitive services to use name and
   logo of utility.

 .  SB 438 does not impair rights under existing electric service contracts or
   labor agreements.

 .  Utilities may enter into contracts with customers prior to March 1, 2000;
   specifies that alternative sellers may aggregate two or more customers;
   prohibits PUCN from limiting ability of alternative sellers to aggregate
   customers and for customers to form groups for aggregation.

 .  Allows the PUCN to use "hearing officers" to conduct hearings.

         During the hearing on the proposed past cost rule on June 1, 1999, the
PUCN determined that the impacts of SB 438 on existing and proposed electric
restructuring regulations should be evaluated. The PUCN issued Procedural Orders
13 and 14 and held workshops to discuss the impact of SB 438.

         See the Company's Annual Report Form 10-K for more information
regarding the issues being considered as a result of restructuring of the
electric industry in Nevada. The following are highlights of recent
restructuring activity:

Compliance Plan (Dockets 99-4001/4002)

         On April 1, 1999, the Company filed Phase I, the revenue requirements
and unbundling study portions, of the Restructuring Compliance Filing with the
PUCN. The filing includes the development of electric revenue requirements for
the test period 1998. In the unbundling study, the revenue requirements were
assigned and allocated to a number of service components including generation,
aggregation, transmission, distribution, metering, billing, and customer
services. On April 30, 1999, the Company filed Phase II which included the
proposed bundled rate design. Phase III will be filed 15

                                       16
<PAGE>

days following a PUCN decision on Phases I and II and will include full proposed
tariffs for distribution service and all other noncompetitive services

         On September 23, 1999, the PUCN issued an interim order on the
Company's Phase I Compliance Plan filing. The order contained the PUCN's
decision on revenue requirements, return on equity, depreciation, and the
unbundling study. The PUCN's decision establishes a new (lower) revenue
requirement for the vertically integrated electric utility that is based on a
return on equity rate of 10.25%, changes to generation and distribution
depreciation rates, other rate base and operating expense adjustments. The order
also establishes an electric distribution return on equity rate of 9.85% that
reflects a 40 basis point risk adjustment from the integrated electric utility.
The Company believes that SB 438 established the current revenue requirement for
the vertically integrated electric utility as present rate revenues. However,
the order denied the Company's motion to consider the impacts of SB 438 on the
Compliance Plan filing. The Company filed a Petition for Reconsideration and the
Phase II Compliance Plan filing on October 8, 1999.

Distribution Open Access Tariffs

         On January 7, 1999, the PUCN issued an order adopting a final rule for
distribution tariffs (adopted as a temporary regulation). On February 1, 1999
the Company filed proposed language for distribution tariffs and filed testimony
in support of its distribution tariffs filing on March 9, 1999. On April 9, 1999
a stipulation resolving most issues and agreeing to further filings on
unresolved issues was filed with the PUCN.

         The Company and Nevada Power conducted informal workshops with the
appropriate parties to resolve issues related to Rules 9 (Line Extensions) and
15 (Non-Utility Generation Facilities) of the Distribution Open Access Tariffs.
Rule 9 provides for competition in line extension designs and construction while
Rule 15 provides procedures for the connection of non-utility generators. A
settlement was reached resolving Rule 15 and filed with the PUCN on June 18,
1999. Another settlement was reached resolving Rule 9 and was filed with the
PUCN on July 9th.

Past Costs

         Past costs, which are commonly referred to as stranded costs in other
jurisdictions, continue to be addressed in 1999. AB366 permits the recovery of
generation costs pursuant to specified legal criteria. The PUCN has conducted
several workshops on past costs in which various topics were discussed,
including the characteristics that define recoverable past costs, criteria for
evaluating the effectiveness of mitigation efforts, options for cost recovery
mechanisms and applicable tax and accounting issues.

         On April 8, 1999, the PUCN issued a revised proposed rule that
specifies the information a utility must include in its request for recovery of
past costs. The final rule is expected to include the date for the submission of
filings to recover past costs, which will likely be 45 days after the order from
the compliance plan filing is issued.

         On June 1, 1999, the PUCN began and suspended the hearing on the
proposed past cost rule. Due to the passage of SB 438, the PUCN determined that
this rule and other regulations should be evaluated to investigate the impact of
SB 438 has on this and other pending and adopted regulations. The PUCN has
scheduled a hearing on November 8, 1999, on the proposed past cost rule. The
Company has not completed an estimate of its past costs, since such a
calculation is dependent on a variety of issues related to restructuring which
are not resolved at this time. These rules are expected to be completed and any
required past cost filing will be made late in 1999 or early 2000.


Provider of Last Resort

         The provider of last resort (PLR) will provide electric service to
customers who do not select an electricity provider and to customers who are not
able to obtain service from an alternative seller after the date competition
begins. On March 16, 1999 the PUCN issued a revised proposed rule for PLR. A
hearing was held April 26, 1999. A new procedural final order was issued
regarding those matters.

         The PUCN proposed PLR format requires the PLR functions to be performed
by a regulated affiliate of the Company and not by the electric distribution
utility. The business activities of the PLR affiliate must be limited to the PLR
function. The Company and Nevada Power filed joint comments which outlined
concerns that the PUCN proposed PLR format would not be financially viable. The
PUCN issued Procedural Order 11 to request comments on the financial viability
of the PUCN proposed PLR format.

                                       17
<PAGE>

         SB 438 specifically provides for the electric distribution utility to
provide PLR services until July 1, 2001. The PUCN has scheduled a workshop on
November 8, 1999 on a new proposed rule for the PLR.

Independent Scheduling Administrator

         The Company has participated in interim Independent Scheduling
Administrator (iISA) working groups which are developing iISA standards,
protocols and procedures. The PUCN issued a "Notice of Request for Comments and
Notice of Workshop" to hear from entities interested in performing the iISA
function, the timeline, the functions to be performed, the costs and how these
entities will adhere to the PUCN iISA principles. The PUCN held a workshop on
the proposed iISA on July 14, 1999. Presentations were made by the Mountain West
ISA and the California ISO. The workshop was continued on July 22, 1999.

         On behalf of the Mountain West ISA, the Company and Nevada Power
submitted a filing to establish the ISA with the Federal Energy Regulatory
Commission ("FERC") on July 23, 1999. See "Regulatory Matters - FERC Matters-
Independent Scheduling Administrator (ISA)". The PUCN held a workshop to discuss
the adequacy of the ISA proposal.

         On September 13, 1999, the Company and Nevada Power filed a brief on
recovery of ISA funding. On September 17, 1999, the PUCN issued a Procedural
Order setting the schedule for a hearing on the ISA filing. The PUCN identified
two issues for the hearing on October 25, 1999: ISA funding and pre-existing
contracts. The PUCN also requested parties to file a list of additional issues.
The Company and Nevada Power filed a response to the PUCN Procedural Order and
testimony for the hearing.

Meter and Data Exchange

         The PUCN issued a Notice of Tariff Filing and Notice of Hearing on
meter and data exchange standards and protocols on September 23, 1999. The
hearing was held on October 27, 1999 and an order on the issue is pending.

Gas Restructuring

         To comply with Nevada AB 366 for natural gas deregulation, the PUCN is
developing new natural gas rules. To develop new rules, the PUCN is following
similar processes as in electric restructuring.

Gas Licensing

         On January 7, 1998, the PUCN issued an order adopting a final rule for
licensing which was adopted as a temporary regulation.

         On February 9, 1999, the PUCN issued a proposed rule for gas licensing
fees. On March 23, 1999 the PUCN held a workshop on the proposed rule for
licensing fees for alternative sellers. The hearing, also scheduled for this
day, was postponed. The PUCN re-issued the proposed rule and held hearings in
March and June. The PUCN is expected to adopt the proposed rule at its next
agenda meeting.



                              California Matters

Rate Reduction Bonds

         California's electricity restructuring statute (Assembly Bill 1890,
Chapter 854, California Statutes of 1996, as amended), permits California
investor-owned utilities, including the Company, to finance the recovery of a
reduction in electricity rates for residential and small commercial customers
through the issuance of rate reduction certificates. Transition costs consist of
the costs of generation-related assets and obligations that may become
uneconomic as a result of a competitive generation market, together with certain
other costs associated therewith.

         In order for the Company to recover transition and associated costs,
the California Public Utilities Commission (CPUC) authorized the establishment
of non-bypassable, usage-based, per kilowatt hour charges ("FTA Charges") to be
included in the regular utility bills of residential and small commercial
consumers located in the historical service territory

                                       18
<PAGE>

of the Company in California. The right to receive payments made in respect of
the FTA Charges is referred to as Transition Property.

         On April 9, 1999, the Company sold the Transition Property to SPPC
Funding LLC, a Delaware special purpose limited liability company whose sole
member is the Company, in exchange for the proceeds of the SPPC Funding LLC
Notes, Series 1999-1 (the "Underlying Notes"). SPPC Funding LLC then issued and
sold the Underlying Notes to the California Infrastructure and Economic
Development Bank Special Purpose Trust SPPC-1 (the "Trust") in exchange for the
proceeds of the sale of the Trust's $24.0 million 6.4% Rate Reduction
Certificates, Series 1999-1 (the "Certificates"). The Trust, which had been
established by the California Infrastructure and Economic Development Bank,
issued and sold the Certificates in a private placement pursuant to Rule 144A
under the Securities Act of 1933, as amended. The Certificates are one of a
series of rate reduction certificates that may be issued from time to time by
the Trust and sold to investors upon terms determined at the time of sale.

Revenue Cycle Unbundling

         On February 18, 1999, the CPUC approved the Company's proposed Revenue
Cycle Services Credits (RCSC) application filed February 2, 1998. The RCSC
addresses meter ownership, meter services, meter reading, and billing and
applies to customers who select their own provider of a revenue cycle service.
On April 9, 1999, the Company made a compliance tariff filing which reflects the
approved credits.

Direct Access Tariffs

         On April 5, 1999, the CPUC approved the Company's compliance filing,
effective back to March 18, 1998, which proposed tariff changes to implement
direct access.

Rate Unbundling

         On April 5, 1999, the CPUC approved the Company's proposed unbundled
rates effective back to June 1, 1998.

Distribution Competition

         The CPUC has opened a docket item to solicit comments and proposals on
distributed generation and competition in electric distribution service. It is
too early to determine how this proceeding may affect the Company.

Generation Divestiture

         The Company has filed with the CPUC its request for approval to sell
its generation plants.

                                 FERC Matters

Alturas

         On April 15, 1999 the FERC approved the settlement in the Import Limit
Case which had previously been certified by the Administrative Law Judge in June
1998. The settlement provides for a continuation of the current import limit
allocation until the Alturas intertie is in service. At that time and until
February 28, 2001, Truckee Donner Public Utility District (TDPUD) will receive
30 MW of import capability. After February 28, 2001, allocation of import
capacity will be determined by the FERC based on the results of the Company's
1998 Resource Plan and a subsequent filing with the FERC in 1999.

Regional Transmission Organizations

         On May 13, 1999, the FERC issued a Notice of Proposed Rulemaking on
Regional Transmission Organizations (RTOs). The FERC proposed characteristics of
an RTO and also the requirement for utilities to form or join RTOs.

Merger

                                       19
<PAGE>

         On April 14, 1999, the FERC voted to approve the merger of SPR, the
Company and Nevada Power, as proposed. In approving the merger the FERC required
the companies to divest of their generation facilities (as proposed by the
companies) and required Nevada Power to file an update of its transmission rates
(also proposed by the companies).

         On May 17/th/, TDPUD filed a Petition for Rehearing of the FERC's order
approving the merger. TDPUD claims the FERC violated its own policy by allowing
the merger to be consummated prior to divestiture of generation assets. The
Company and Nevada Power filed an answer to TDPUD's Petition for Rehearing in
May. On July 14, 1999, the FERC denied in all aspects TDPUD's petition.

Transmission Rate Case

         On March 30, 1999, the Company filed with the FERC to increase its open
access transmission rates. The Company requested an increase of $16 million in
the annual revenue requirement for network service. The point-to-point rate
would increase from $2.80 /kW-mo. to $3.21 /kW-mo. This filing incorporates the
Alturas intertie, completed in December 1998, and the reclassification of
transmission and distribution facilities approved by the PUCN last summer.

         On May 28, 1999, as expected, the FERC issued an order setting the rate
case for hearing. The proposed rates are accepted subject to refund and
suspended until November 1, 1999. On June 14, 1999, as required by the May 28
order, the Company filed additional information on the proposed transmission and
distribution (T&D) reclassification. The Company also requested that the FERC
accept the filing and approve the T&D split. On July 29, 1999 the FERC accepted
the Company's proposed T&D reclassification. The hearing will commence on
January 25, 2000.

Generation Tariffs

         On March 31, 1999, the Company filed Docket No. ER99-2332 with the FERC
for approval of generation tariffs that contain the rates, terms and conditions
under which the new owners of the Company's generation would operate after
divestiture. The tariffs permit market-based rates after the offering of
capacity under a cost-based recourse approach.

         Motions to intervene and protest in the Company's generation tariffs
rate case were due on April 20, 1999. Newmont, City of Fallon, and TDPUD filed
motions to intervene and protest. Barrick (a mining company) filed a motion to
intervene with comments. Several other parties also filed interventions. The
PUCN filed motion to intervene and protest one day after the date established by
the FERC. The PUCN requested the FERC to hold the proceedings in abeyance to
allow the PUCN more time to review Sierra's divestiture plan filing.

         The Company filed an Answer to the protests filed on the tariff on
May 5, 1999. In response to the PUCN request, the Company requested that the
FERC rule on the Company's tariff by November 30, 1999 (rather than September
30, 1999) to allow the PUCN more time. The Company also provided clarification
in response to other protests.

         On July 20, 1999, the Company filed a motion to expedite the FERC's
consideration of the tariff. The motion requested that the FERC approve the
tariff by September 30, 1999 since the PUCN issues were resolved.

Independent Scheduling Administrator (ISA)

         On July 23, 1999, the Company and Nevada Power submitted a filing to
establish the Mountain West ISA (Docket ER97-3719). The proposal centers on the
formation of an interim ISA called Mountain West ISA, which will ensure the non-
discriminatory treatment of transmission customer in two wholesale electricity
markets; one in northern Nevada and one in southern Nevada. The formation of the
ISA is viewed as an interim step in the move to broader regional restructuring
of the electric service industry in the western United States.

         Fifteen parties filed to intervene in the ISA filing. On September 17,
1999, the Company, Nevada Power and the Mountain West ISA filed answers to the
protests filed on the ISA filing. The California ISO filed an answer to the
Company's and Nevada Power's response to their protest on September 28, 1999.

Year 2000 Issues
- ----------------

                                       20
<PAGE>

         To the maximum extent permitted by applicable law, the following
information is being designated as a "Year 2000 Readiness Disclosure" pursuant
to the "Year 2000 Information and Readiness Disclosure Act" which was signed
into law on October 19, 1998.

         The Company uses business application software programs and relies on
computing infrastructure that includes embedded systems that have a Year 2000
(Y2K) affect on the Company. In many cases, the Company's software programs and
embedded systems use two-digit years that may recognize a date using `00' as the
year 1900 rather than the year 2000. This could result in the computer or device
shutting down, performing incorrect computations, or performing in an
inconsistent manner.

         In 1996, the Company established its Y2K project to address Y2K issues.
The project's scope includes: (1) business application systems (including, but
not limited to, customer information and billing) and financial systems
(including time reporting, payroll, general ledger, accounts payable and
purchasing, and end-user developed systems); (2) embedded systems (including
equipment that operates or controls operating facilities such as power plants,
electric transmission and distribution, water, gas, telecommunications, and
information technology systems); (3) customer, vendor, and supplier
relationships and (4) testing and contingency planning.

         To implement its Y2K strategies, the Company established a Y2K project
office currently headed by the Chief Financial Officer. This office includes an
oversight committee representing all lines of business, and a "champions team"
representing electric generation, transmission and distribution, gas
distribution, water production and distribution, telecommunications, systems
control, computer infrastructure and building facilities. Also represented are
internal audit, engineering, procurement, legal, and human resources. In
addition, the Company has utilized the expertise of outside consultants to
assist in the project management and the technical aspects of the project.

Business Application Systems

         The initial focus for the Y2K project team was on the business
application systems. In the fall of 1996 the Company purchased software
assessment tools and completed its inventory and code assessment for its
mainframe business systems. The inventory is comprised of over 7 million lines
of COBOL code, and end-user programs.

         The Company developed and strictly adheres to a Y2K methodology that
includes unit, system wide and Y2K date specific testing.

         The Company has successfully completed implementing 100% of its mission
critical business systems.

Embedded Systems

         The Company hired an outside engineering consultant, Network Systems
Engineering Corporation (NSEC), to assist the Company's staff in conducting a
thorough and comprehensive inventory of its embedded systems at the component
level. All systems have been inventoried and assessed. This inventory identified
over 2,500 potentially date sensitive items. The Company and NSEC have contacted
all manufacturers of those components that they have identified as critical to
operations and continues to contact other manufacturers of embedded system
components to determine if their components are Y2K ready. As of June 30, 1999,
100% of the Company's mission critical embedded systems are Y2K ready.

         The Company's Y2K readiness activities are tracked and reported monthly
to the North American Electric Reliability Council (NERC), an association
comprised of all segments of the electric industry. NERC expects utilities to
have completed all Y2K testing and remediation by June 30, 1999. The Company has
met that expectation and has filed a letter with NERC expressing its readiness.

         The Company participated in the North American Electric Reliability
Council's (NERC) September 9, 1999 nation-wide readiness drill for utilities.
The purpose of the drill was to test alternative lines of communications by
simulating loss of data and voice communications, and to train and prepare staff
for the millennium date rollover. The Company experienced a few minor procedural
problems, that have since been corrected.

         In September 1999, the Company completed an independent audit conducted
by Sargent and Lundy (S&L). In summary the S&L final report stated, "During the
course of the audit, S&L discovered no evidence to indicate that mission
critical systems at selected power stations would not perform as expected...."

                                       21
<PAGE>

Vendors and Suppliers

         The Company has contacted, in writing, all vendors and suppliers of
products and services that it considers critical to its operations. These
contacts have included, but were not limited to, suppliers of interstate
transportation capacity for coal supplies, natural gas producers, financial
institutions, and telephone service providers. The Company has met one on one
with several of its critical vendors and suppliers to assess their Y2K
readiness. From these meetings, the Company feels that these vendors and
suppliers have a viable Y2K program and that they will meet their commitments to
the Company. If it becomes necessary, the Company may consider new business and
procurement alternatives for products and services as necessary to the extent
that alternatives are available.

Major Customers

         The Company has met face to face with many of its major customers to
share its progress on Y2K. Also discussed at these meetings is the customer's
Y2K readiness. The Company will continue to keep its major customers informed as
to its progress on Y2K remediation, testing and contingency planning.

Contingency Planning

         The Company's Y2K strategies include contingency planning for both
business and embedded systems. The planning effort includes critical Company
areas such as electric generation, water, gas, telecommunications, building
facilities, information technology, networks, vendors, suppliers, and operations
personnel. Quick action response teams and additional Company personnel are
planned to be available for the century rollover. Additionally, the Company's
Emergency Operations Center (EOC) will be activated for the century rollover.
All Company contingency plans were completed as of September 30, 1999.

         As part of its normal business practice, the Company maintains plans to
follow during emergency circumstances, some of which could arise from Y2K
problems.

Potential Risks

         With respect to its internal operations, those over which the Company
has direct control, the Company believes the most significant potential risks
from Y2K problems are: (1) its ability to use electronic devices to control and
operate its generation, gas, water, telecommunication, transmission and
distribution systems; (2) its ability to render timely bills to its customers;
and (3) the ability to maintain continuous operations of its computer systems.

         The Company depends upon external parties, including customers,
suppliers, business partners, gas and electric system operators, government
agencies, and financial institutions to reliably deliver their products and
services. The Company believes that its most reasonable likely worst case
scenario is the extent to which any of these parties experiences Y2K problems in
their system. Should any of these critical vendors fail, the impact of any such
failure could become a significant challenge to the Company's ability to meet
the demands of its customers. Business continuity interruption could also have a
material adverse financial impact, including but not limited to, lost sales
revenues, increased operating costs, and claims from customers related to
business interruptions. Based upon the information supplied to date by our
critical vendors and suppliers, the Company believes the probability of such
failures is low. The Company is monitoring the progress of these critical
entities and contingency plans are being developed to address the potential
failure of an external party to be Y2K ready.

Financial Implications

         With 100% of mission critical components tested, findings indicate that
the transition through critical Y2K dates is expected to have minimal impact on
the Company's Electric, Gas, and Water operations. These results are reflected
in reduced costs discussed below.

         The Company currently estimates that its total incremental expenditures
for the Y2K effort, since it began identification of Y2K cost, will be
approximately $5.9 million. This estimate has been reduced from amounts
previously reported based on updated assessments of the project costs. Y2K costs
include assessment, remediation, testing, and contingency planning activities.
Of the total project costs, about $4.0 million was incurred through September
30, 1999.

                                       22
<PAGE>

         Approximately $2.5 million of the expenditures relate to business
systems, and $1.5 million relate to the Company's embedded systems. The Company
anticipates that the remaining expenditures will be spent on remediating non-
mission critical systems, and equipment necessitated by the contingency plans.

         The Company's Y2K program is progressing and the Company believes it is
taking all reasonable steps necessary to be able to operate successfully through
and beyond the turn of the century.
