New Century  Energies,  Inc. and Northern  States Power Company hereby amend and
restate in its entirety their  Application-Declaration  in File No. 70-9539,  as
previously amended, and file additional exhibits thereto.



Item 1.  Description of Proposed Transaction

A.   Introduction

     This  Application-Declaration  seeks  approvals  relating  to the  proposed
combination (the "Merger") of New Century Energies, Inc., a Delaware corporation
("NCE"),  and Northern States Power Company,  a Minnesota  corporation  ("NSP").
Upon receipt of all necessary  approvals,  NCE will be merged with and into NSP,
which will be renamed Xcel Energy Inc. ("Xcel"). Also as part of the Merger, NSP
intends to  transfer  all of its  existing  electric  and  natural  gas  utility
facilities  and  operations  currently  conducted  directly by NSP at the parent
company level to a newly formed,  wholly-owned subsidiary (referred to herein as
"New NSP").  Following the  consummation of the Merger,  Xcel will register with
the Securities and Exchange  Commission (the  "Commission") as a holding company
under the Public Utility Holding Company Act of 1935, as amended (the "1935 Act"
or the "Act")./1

     The  combination  of NSP and NCE, two  well-run,  mid-sized,  mid-continent
energy companies,  will result in a financially strong and competitive  regional
energy  company.  A key  motivating  factor for the proposed  transaction is the
shared vision by the senior  managements of both NSP and NCE (the  "Applicants")
concerning  the  changes  that are  occurring  in the utility  industry  and the
actions needed to respond effectively to those changes.  The Merger will produce
substantial  benefits to the public,  consumers  and investors and will meet all
applicable standards of the Act. Among other things, the Applicants believe that
the Merger offers  significant  strategic and financial benefits to each company
and to their respective shareholders,  as well as to their employees,  customers
and the  communities in which they do business.  These benefits  include,  among
others:

          (i)       increased  scope,  providing  an  infrastructure  capable of
                    supporting more efficient  utility  operations,  non-utility
                    business activities and corporate services;

          (ii)      increased  stability and  competitiveness of rates resulting
                    from fuel diversification and operating  efficiencies,  thus
                    improving  Applicants' ability to meet the challenges of the
                    increasingly   competitive   environment   in  the   utility
                    industry;

          (iii      integration  of corporate and  administrative  functions and
                    programs,  including centralized management and coordination
                    and operation of utility systems;

----------
1    Prior to completion  of the Merger,  NSP and NCE expect to file one or more
     additional  applications-declarations under the Act with respect to ongoing
     activities (including financing activities) and other matters pertaining to
     Xcel after the Merger.
----------


          (iv)      savings from the  coordinated  dispatch and operation of the
                    combined generating assets of the Applicants;

          (v)       enhanced financial  stability and strength through increased
                    market   capitalization   and  a  stronger   balance  sheet,
                    improving  access to  capital  markets,  and  capability  to
                    support the growth  objectives  established  for non-utility
                    businesses,  including NSP's largest non-utility subsidiary,
                    NRG Energy;

          (vi)      increased   geographic  diversity  of  service  territories,
                    reducing exposure to local changes in economic,  competitive
                    and climatic conditions, enabling Xcel to withstand risk and
                    volatility  better than  either NSP or NCE on a  stand-alone
                    basis;

          (vii)     greater   purchasing  power  for  items  such  as  fuel  and
                    transportation services, and streamlining of inventories;

          (viii)    expanded   management   resources   and  ability  to  select
                    leadership from a larger and more diverse management pool;

          (ix)      continued  ability  to play a  strong  role in the  economic
                    development  efforts of the communities  that the Applicants
                    now serve; and

          (x)       a strong  global  presence,  with  operations  in the United
                    Kingdom, Central Europe, Australia and South America.

In  summary,  Applicants  believe the Merger will  significantly  improve  their
competitive  positions  and  create an  enhanced  platform  for  growth  for all
segments of their businesses.  Applicants estimate that efficiencies  created by
the Merger will  generate  cost  savings of  approximately  $1.1 billion (net of
costs to achieve) in the first ten years  following  the  Merger.  The  expected
Merger benefits are discussed in further detail in Item 3.C.2. below.

     The  shareholders of NCE and NSP approved the Merger on June 28, 1999, with
more than 83% of the votes cast by the shareholders of each  corporation  voting
in favor of the  Merger.  Various  aspects of the  Merger  and the  transactions
relating thereto have been submitted for review and approved by: (i) the Arizona
Corporation Commission (the "Arizona  Commission"),  (ii) the Kansas Corporation
Commission  (the "Kansas  Commission"),  (iii) the  Minnesota  Public  Utilities
Commission (the "Minnesota  Commission"),  (iv) the New Mexico Public Regulation
Commission  (the "New Mexico  Commission"),  (v) the North Dakota Public Service
Commission (the "North Dakota Commission"), (vi) the Public Utilities Commission
of the State of Colorado (the "Colorado  Commission"),  (vii) the Public Utility
Commission of Texas (the "Texas Commission"),  (viii) the Wyoming Public Service
Commission  (the  "Wyoming  Commission"),  (ix) the  Federal  Energy  Regulatory
Commission (the "FERC") and (x) the Nuclear  Regulatory  Commission (the "NRC").
Completion  of the  Merger  is also  subject  to the  waiting  period  under the
Hart-Scott-Rodino  Antitrust  Improvements  Act of 1976,  as  amended  (the "HSR
Act"), which expired on March 1, 2000.  Approval will also be necessary from the
Federal  Communications  Commission  (the  "FCC")  in  connection  with  various
licenses.  In addition,  NSP possesses various franchises,  permits and licenses
granted by local and state  authorities  that NSP may need to  assign,  renew or
replace as a result of the Merger. The status of these approvals,  including the
approvals by FERC/2 and each state commission,  is explained in detail in Item 4
below.  Apart from the approval of the  Commission  under the Act, the foregoing
approvals are the only governmental  approvals required for the Merger. In order
to  permit  timely  consummation  of  the  Merger  and  the  realization  of the
substantial  benefits it is expected to produce, the Applicants request that the
Commission's  review of this  Application-Declaration  commence  and  proceed as
expeditiously as practicable.

B.   Overview of the Transaction

     NCE and NSP have entered into an Agreement and Plan of Merger, dated as
of March 24,  1999 (the  "Merger  Agreement"),  which  provides  for a strategic
business combination involving NCE and NSP in a "merger-of-equals"  transaction.
Pursuant to the Merger Agreement,  NCE will merge with and into NSP. NSP, as the
surviving  corporation,  will  change  its  name to Xcel.  Also,  as part of the
Merger,  NSP is expected to transfer its existing  utility  operations  that are
being  conducted  directly by NSP at the parent  company level to New NSP, which
will be a wholly-owned subsidiary of Xcel./3 Upon completion of the Merger, Xcel
will have the following public-utility subsidiary companies: Southwestern Public
Service Company, a New Mexico corporation  ("SPS"/)4;  Public Service Company of
Colorado,  a  Colorado  corporation  ("PSCo");  Cheyenne  Light,  Fuel and Power
Company, a Wyoming  corporation  ("Cheyenne");  Northern States Power Company, a
Minnesota  corporation  ("New  NSP");  and  Northern  States  Power  Company,  a
Wisconsin  corporation  ("NSP-W").  Black  Mountain Gas Company  ("BMG"),  which
currently  operates  in  Arizona  as a  division  of NSP,  is also to  become  a
public-utility  subsidiary of Xcel./5 New Century  Services, Inc.,  the existing
service  company  for the NCE system,  will be the service  company for the Xcel
system under  Section 13 of the Act,  although it is expected to be renamed Xcel
Energy  Services  Inc.  In  addition,  Xcel  will  continue  to own all of NSP's
existing  non-utility  subsidiaries  and  will  acquire  all of the  outstanding
capital stock of the  non-utility  subsidiaries of NCE. See Exhibit E-12 for the
resulting corporate structure of Xcel./6

-----------
2    Northern States Power Company, 90 FERC P. 61,020 (2000) (herein,  the "FERC
     Merger Order").

3    The Merger Agreement  provides that NSP shall not be obligated to undertake
     the above  restructuring if it would cause a NSP Material Adverse Effect as
     defined in that  document,  and, if a NSP  Material  Adverse  Effect  would
     result,  the parties  must  negotiate in good faith an  alternative  to the
     restructuring.

4    As noted below, SPS is required to restructure to comply with restructuring
     legislation  enacted in Texas and New Mexico.  However, it is expected that
     such restructuring will take place subsequent to the Commission's action on
     this  application.  Any  necessary  authorizations  of  the  Commission  to
     implement the SPS  restructuring  will be requested at the appropriate time
     in a separate application.

5    Presently  pending before the Commission is NSP's  application for approval
     to transfer the assets and  operations  of BMG to a subsidiary of NSP (File
     No.  70-09337).  NSP's intent is to accomplish  the transfer of such assets
     promptly  upon  receipt of the  necessary  regulatory  approvals.  If these
     approvals are obtained  prior to  consummation  of the Merger,  BMG will be
     Xcel's sixth public-utility subsidiary company.

6    In the event that a different  corporate  structure is adopted,  Applicants
     will file a revised version of EXHIBIT E-12 by amendment. Moreover, to give
     the  Xcel  system  maximum   flexibility  to  reorganize  its   non-utility
     operations  in  the  future  and to  eliminate  unnecessary  burden  on the
     Commission,  Applicants  intend  through a separate  application  to make a
     request for blanket authority to reorganize Xcel's non-utility subsidiaries
     and to establish new intermediate  holding  companies,  similar to what the
     Commission has authorized for other registered systems. See Columbia Energy
     Group, Holding Co. Act Release No. 27099 (Nov. 5, 1999).

     A copy of the Merger Agreement is incorporated by reference as Exhibit B-1.

C.   Description of the Parties to the Merger

     1.   NCE and its Subsidiaries

     NCE is a registered  public utility holding company formed in 1997 pursuant
to Commission  order. New Century  Energies,  Inc.,  Holding Co. Act Release No.
26748  (Aug.  1,  1997)   (herein,   the  "1997  NCE  Order").   NCE  has  three
public-utility  subsidiaries,  PSCo,  SPS and  Cheyenne,  which are  referred to
herein collectively as the "NCE Operating  Companies." PSCo serves approximately
1.2 million electric  customers and  approximately  1.0 million gas customers in
the state of Colorado.  SPS serves  approximately  385,000 electric customers in
portions of the states of Texas,  New  Mexico,  Oklahoma  and  Kansas.  Cheyenne
serves  approximately  35,000 electric customers and 28,000 gas customers in and
around Cheyenne,  Wyoming. Maps of the electric and gas service areas of the NCE
Operating Companies are filed as Exhibits E-4.1 and E-4.2.

     PSCo's transmission facilities are located in Colorado. PSCo is a member of
the Western Systems  Coordinating  Council  ("WSCC"),  an interstate  network of
transmission  facilities  that are owned by public  entities and  investor-owned
utilities. WSCC is the regional reliability coordinating organization for member
electric  power  systems  in the  entire  western  electric  grid (the  "Western
Interconnect")  of the  United  States.  PSCo is also a  member  of the  Western
Systems Power Pool ("WSPP"),  an economic power pool that operates an electronic
bulletin board and acts as a  clearinghouse  for bulk power  transactions  among
over 90 member  utilities  and  marketers.  The WSPP  arrangement  provides  for
short-term energy and capacity exchanges at market-based prices for most members
and electronic bulletin board posting of available power and energy.

     PSCo's  transmission  system is directly  interconnected  with Western Area
Power Administration  ("WAPA") in the WSCC. PSCo is also directly interconnected
with Basin Electric Power Cooperative,  PacifiCorp, Platte River Power Authority
and Tri-State Generation and Transmission  Cooperative.  Nearby PSCo are the two
high voltage direct current ("HVDC")  interconnections  between the WSCC and the
eastern electrical grid (the "Eastern Interconnect"): 100 MW at Stegal (owned by
Tri-State) and 200 MW at Sidney (owned by WAPA). For 1999,  PSCo's peak load was
4,951 MW at a time when its net capability was 5,259 MW,  including  1,856 MW of
long-term purchase  contracts.  PSCo's 2000 projected peak load is 5,114 MW, and
its net capability, including 2,019 MW of long-term purchase contracts, is 5,704
MW.

     Cheyenne's transmission facilities are located in Wyoming. These facilities
are very limited, consisting of two 115 kV transmission line segments that total
25.5 miles in length.  The  primary  purpose of these  transmission  lines is to
interconnect Cheyenne's distribution system with the WAPA transmission system to
enable Cheyenne to purchase its power  requirements  from other parties to serve
its  retail  load.  At  present,  PacifiCorp  is  Cheyenne's  full  requirements
supplier.  Unlike PSCo and SPC,  Cheyenne does not have any wholesale load. Like
PSCo, Cheyenne is a member of the WSCC.

     SPS's  transmission  system  is  located  in parts of  Texas,  New  Mexico,
Oklahoma and Kansas.  SPS is a member of the Southwest  Power Pool ("SPP"),  the
regional  reliability  council for member electric power systems in an area that
encompasses  portions of the South, the Southwest,  and the Great Plains. SPS is
also a member of WSPP.

     SPS's transmission system is interconnected with two SPP-member  utilities,
Public Service Company of Oklahoma (an operating  company within the Central and
South West system) and West Plains Energy-Kansas (a division of UtiliCorp United
Inc.),  which enables it to purchase or sell energy from power  producers in the
Eastern Interconnect.  It is also interconnected with the WSCC via a 200 MW HVDC
tie near Clovis,  New Mexico (Public Service Company of New Mexico) and a 200 MW
HVDC tie at Artesia,  New Mexico (El Paso Electric  Company and Texas-New Mexico
Power  Company),  which  allows  SPS to  purchase  and sell  energy  from  power
producers in the Western Interconnect. For 1999, SPS's peak load was 3,946 MW at
a time  when its net  capability  was 4,647 MW,  including  396 MW of  long-term
purchase  contracts.  SPS's  2000  projected  peak load is 4,332 MW, and its net
capability, including 670 MW of long-term purchase contracts, is 5,024 MW.

     In connection  with their 1997 merger,  PSCo and SPS stated their intent to
construct a new tie line to interconnect  their combined electric systems within
five years after the  consummation  of that merger.  Following a joint  planning
process that involved input from over fifty participants,  the final project was
selected in August 1998. In early January 1999, after further  evaluation,  PSCo
and SPS announced plans for the phased approach for the  implementation  of this
project and the construction of additional  transmission facilities to alleviate
transmission  constraints,   increase  reliability  and  provide  energy  supply
alternatives in SPS's present service  territory in anticipation of competition.
This expansion is expected to be completed in a phased approach and will require
various  regulatory  approvals.  The first phase will involve  construction of a
230-mile,   345  kV  line  from   Amarillo,   Texas  to  Holcomb,   Kansas  (the
"Amarillo-Holcomb line") and is expected to be completed in the third quarter of
2001./7 The second phase will consist of construction of a 100-mile, 345 kV line
from  Holcomb,  Kansas  to  Lamar,  Colorado  and a  HVDC  facility  that  would
interconnect  the PSCo  and SPS  systems,  as well as the WSCC and SPP  regional
transmission  grids.  This second phase is now scheduled for  completion in 2004
and  will  establish  the  fifth  HVDC   interconnection   between  the  Western
Interconnect  and  Eastern  Interconnect./8  While not  directly  related to the
interconnection  of the PSCo and SPS  systems,  the third phase of this  project
will  involve  construction  of an  approximately  275-mile,  345 kV  line  from
Amarillo,  Texas to Oklahoma City, Oklahoma.  The completion of this line is not
expected before 2004.  Further  information on the utility assets and operations
of the NCE Operating Companies is included in Annex A.

----------
7    The phased  approach for the  tie-line  will enable PSCo to comply with the
     procedural requirements of the Colorado Commission.  In a recent order, the
     Colorado  Commission  has made  clear that PSCo must seek its  approval  to
     construct  the  portion of the  tie-line  to be located  in  Colorado  in a
     certificate  of  public   convenience   and  necessity   proceeding.   PSCo
     anticipates  filing  the  necessary  CPCN  application  with  the  Colorado
     Commission by September 29, 2000.  Applicants have included as Exhibit K to
     this  Application  a  memorandum  detailing  the  steps  that NCE has taken
     towards  fulfilling  its  interconnection  obligations  under  the 1997 NCE
     Order, and the steps that NCE expects to take, including those necessary to
     meet Colorado  regulatory  requirements,  to achieve an in service date for
     the second phase of the tie-line,  thereby completing the tie-line project,
     by year-end 2004. In the 1997 NCE Order, the Commission noted that: "In the
     event that New Century Energies at any time determines not to construct the
     tie,  or the tie is not  substantially  completed  within five years of the
     date of consummation of the [PSCo/SPS]  merger,  New Century  Energies will
     file a  post-effective  amendment  concerning  the measures it will take to
     ensure that the  requirements  of section  2(a)(29)(A)  are satisfied." The
     Applicants  believe that  completion of first phase (the  Amarillo  Holcomb
     line) will result in substantial completion of the tie line.  Nevertheless,
     NCE  intends  to file a  post-effective  amendment  in File No.  70-8787 to
     update the record regarding the NCE System's plans to complete the tie-line
     project.

8    In April  1999,  SPS  submitted  an  application  to the Kansas  Commission
     requesting  a  siting  permit  in  Kansas  for  construction  of  both  the
     Amarillo-Holcomb line and the Holcomb-Lamar line. Kansas is the state where
     the longest portion of the two lines will be constructed. SPS has completed
     the detailed routing and environmental  assessment of the proposed location
     of the  lines.  Public  conferences  have  been held in  Colorado,  Kansas,
     Oklahoma  and Texas to  present  information  to  affected  landowners  and
     receive their input.  Hearings on the Kansas  application were held in June
     1999  and,  on July  16,  1999,  the  Hearing  Examiner  in the  proceeding
     recommended  to the Kansas  Commission  that the  location of the lines was
     reasonable.  The Hearing  Examiner  recommended  approval of the  requested
     Siting  Permit,  KCC Docket  No.  99-SWPE-764-MIS.  The  Kansas  Commission
     recently  affirmed  the  Hearing  Examiner's  order.  In the  Matter of the
     Application of  Southwestern  Public  Service  Company for a Siting Permit,
     Docket No. 99-SWPE-764-MIS (KCC July 19, 1999).

2.   NSP and its Subsidiaries

     NSP,  which was  incorporated  in 1909, is a  public-utility  company and a
holding  company  exempt from  registration  pursuant to Commission  order under
Section  3(a)(2) of the Act.  Northern  States  Power  Company,  Holding Co. Act
Release No. 22334 (Dec. 23, 1981). NSP owns all of the outstanding  common stock
of NSP-W, a Wisconsin  corporation,  which is a public-utility company under the
Act.  Maps of the electric  and gas service  areas of NSP and NSP-W are filed as
Exhibits E-3.1 and E-3.2.

     NSP is engaged  primarily in the generation,  transmission and distribution
of electricity throughout a 30,000 square mile service area in Minnesota,  North
Dakota and South Dakota.  NSP also purchases,  distributes and sells natural gas
to retail  customers and  transports  customer-owned  gas in  approximately  118
communities in Minnesota,  North Dakota,  South Dakota and Arizona.  Of the more
than 2.5 million  people served by NSP, the majority are in the  Minneapolis-St.
Paul metropolitan area. In 1999, more than 73% of the electric retail revenue of
NSP was derived from sales in the  Minneapolis-St.  Paul metropolitan  area, and
more than 67% of its retail gas revenue  was derived  from sales in the St. Paul
metropolitan  area.  NSP  provides  both  electric  and gas  utility  service in
Minnesota,  North  Dakota  and South  Dakota  but only gas  utility  service  in
Arizona. NSP provides retail electric utility service to approximately 1,240,000
customers and gas utility service to approximately 400,000 customers.

     NSP-W is engaged  in the  generation,  transmission,  and  distribution  of
electricity  to   approximately   210,400   retail   customers  in  an  area  of
approximately  18,900 square miles in northwestern  Wisconsin,  to approximately
9,100 electric retail customers in an area of approximately  300 square miles in
the  western  portion of the Upper  Peninsula  of Michigan  and to 10  wholesale
customers in the same  general  area.  NSP-W  purchases,  distributes  and sells
natural gas to retail customers or transports  customer-owned natural gas in the
same service territory to approximately  78,000 customers in Wisconsin and 5,000
customers in Michigan.  For the year ended  December  31, 1999,  NSP-W  provided
approximately 15% of NSP's consolidated revenues.

     The  electric  transmission  system of NSP and NSP-W (the "NSP  System") is
located  throughout  the  service  territories  that  NSP  and  NSP-W  serve  in
Minnesota, North Dakota, South Dakota, Michigan and Wisconsin. NSP and NSP-W are
directly connected with each other through numerous transmission lines that they
own,  including one 345 kV transmission  line, two 115 kV transmission lines and
two 69 kV transmission lines.

     NSP and NSP-W are members of the  Mid-Continent  Area Power Pool  ("MAPP"),
the regional  reliability council for numerous electric providers in portions of
the Midwest.  The NSP System is  interconnected  with 19 other utility  systems,
including  utilities  in MAPP (Basin  Electric  Power  Cooperative,  Great River
Energy,  Otter Tail Power Co., WAPA,  Southern Minnesota Municipal Power Agency,
Interstate Energy Co., IES Utilities,  MidAmerican  Energy Co.,  Minnesota Power
Co., Dairyland Power Cooperative and Manitoba Hydro-Electric Board at the United
States/Canada  border)  and  utilities  in  Mid-America  Interconnected  Network
("MAIN") (Ameren, Wisconsin Public Service Corporation, Wisconsin Electric Power
Company and  Wisconsin  Power and Light).  NSP also  participates  in two 345 kV
lines  that  give it  limited  purpose  contractual  interconnections  with  six
additional utilities. The "East 345 Line" runs between Minneapolis-St.  Paul and
St. Louis and includes as  participants  operating  companies of Alliant Energy,
Inc. (IES Utilities Inc. and Interstate Energy Company), Ameren (Union Electric)
as well as MidAmerican  Energy Company and NSP. The "West 345 Line" runs between
Minneapolis-St.  Paul and Kansas City and includes as  participants  Kansas City
Power and Light,  Interstate Energy Company,  MidAmerican Energy Company,  Omaha
Public Power District and St. Joseph Light and Power.

     The combined net generating capability (considering purchases and sales) of
NSP and NSP-W is projected to be 8,411 MW in 2000, against a net demand of 7,171
MW./11  Given  MAPP's  minimum  reliability  reserve  margin  requirement  of 15
percent,  NSP has 164 MW of  uncommitted  capacity in 2000. In 1998 and in 1999,
NSP was a net  purchaser  of  power,  and it  anticipates  being  a  significant
purchaser  in  future  years.  In  the  past,  NSP  relied  increasingly  on the
short-term  energy market to meet increased  customer demand for energy. On June
28,  1999,  NSP  filed a  request  for  proposals  ("RFP")  with  the  Minnesota
Commission.  In this request, NSP identified a need for a long-term capacity and
energy to meet the increased  requirements  of customers  beginning in 2003. The
RFP  identifies  the need to have from 200 to 1200  additional  MW of generation
resources  in service for 2003 or  earlier.  The range is intended to provide an
opportunity to look at a wide variety of potential  future  conditions.  The RFP
permits both acceleration or delay of the in-service date.  Further  information
on the utility assets and operations of NSP and NSP-W is included in Annex B.

----------
11   The electric  production and transmission costs of NSP and NSP-W are shared
     by them. The cost-sharing  arrangement between the companies is referred to
     as the Interchange Agreement. It is a FERC-regulated agreement and has been
     accepted by the  Wisconsin  Commission  and the  Minnesota  Commission  for
     determination of costs recoverable by NSP-W and NSP in rate cases.

----------

     Retail sales rates,  services and other aspects of NSP's retail  operations
are subject to the  jurisdiction of the Minnesota  Commission,  the North Dakota
Commission,  the South Dakota Commission and the Arizona Commission within their
respective states. The Minnesota  Commission also possesses regulatory authority
over  aspects  of NSP's  financial  activities,  including  security  issuances,
property  transfers when the asset value is in excess of $100,000,  mergers with
other utilities,  and transactions between NSP and affiliates.  In addition, the
Minnesota Commission reviews and approves NSP's electric resource and gas supply
capacity plans for meeting  customers' future energy needs.  NSP-W is subject to
regulation  of  similar  scope  by the  Wisconsin  Commission  and the  Michigan
Commission,  except  that the  Michigan  Commission  does not  regulate  NSP-W's
issuances of securities.  In addition, a state commission generally must certify
the  need  for new  generating  plants  and  transmission  lines  of  designated
capacities  to be located  within such state before they may be sited and built.
Wholesale   rates  for  electric  energy  sold  in  interstate   commerce,   the
classification  of accounts,  the interstate  transmission of electric power and
energy,  interconnection  agreements,  issuances of securities  not regulated by
state  commissions,  acquisitions  and sales of certain  utility  properties and
certain other  activities of NSP and NSP-W  (including  the licensing of certain
hydro-electric  facilities)  are  subject  to  the  jurisdiction  of  FERC.  The
operation  and  construction  of NSP's  Prairie  Island and  Monticello  nuclear
facilities are subject to regulation by the NRC. In addition,  NSP and NSP-W are
subject to FERC  jurisdiction  under the NGA with regards to  transportation  or
sale of natural gas for resale.

     NSP  is  also  engaged,  directly  and  through  subsidiary  companies,  in
non-utility businesses. NSP directly provides: (i) an appliance services program
for its residential  customers;  (ii)  construction of natural gas  distribution
systems for third parties (primarily end-users and municipal gas systems); (iii)
sale  of  steam  to  industrial  customers  in  NSP's  service  territory;  (iv)
installation  and  maintenance of street lighting for  municipalities  and other
customers;  (v) propane services; (vi) fuel oil services; and (vii) installation
and maintenance of distributed generation on customer's facilities. In addition,
NSP  owns  directly  the  interests  of  the  following  non-utility  subsidiary
companies: Viking Gas Transmission Company ("Viking"), an interstate natural gas
pipeline subject to FERC jurisdiction under the NGA; NRG Energy, Inc. ("NRG"), a
holding company for many of NSP's non-utility businesses,  including significant
investments in independent power projects and foreign operations; Energy Masters

propane  services;  Nuclear  Management  Company  ("NMC"),  a limited  liability
company that will provide services to the nuclear operations of its members; and
NSP Nuclear Corporation,  a subsidiary formed to hold NSP's interest in NMC. NSP
owns 100% of all of the  foregoing  businesses,  except that NSP owns 25% of the
membership  interests  in NMC and, as a result of the issuance of equity by NRG,
currently has an 82% interest in NRG. A further  description of the  non-utility
subsidiaries of NSP is set forth on Annex D hereto.

     NSP-W owns  directly  all of the  outstanding  common  stock of  Clearwater
Investments,  Inc. ("Clearwater"),  an investor in housing projects that qualify
for low-income  housing tax credits,  and NSP Lands, Inc. ("NSP Lands"),  a real

Improvement  Company  ("C&F"),  a company  that  builds  and  operates  dams and
reservoirs for hydro-electric  plants. A further  description of the non-utility
subsidiaries of NSP-W is also set forth on Annex D hereto.

     NSP Common  Stock is listed on the NYSE and the Chicago  and Pacific  Stock
Exchanges.  As of the close of business on June 30, 2000, there were 157,286,793
shares of NSP Common  Stock and  1,050,000  shares of NSP  cumulative  preferred

12   In this table,  Electric  Utility  revenues are the revenues derived by NSP
     and NSP-W from each company's  operations as an "electric  utility company"
     as defined in Section  2(a)(3) under the Act, and Gas Utility  revenues are
     the revenues  derived by NSP and NSP-W from each company's  operations as a
     "gas utility  company"  under Section  2(a)(4) of the Act. These amounts do
     not conform to NSP's consolidated financial statements, as the consolidated
     financial  statements reflect  eliminations of intercompany  revenues among
     NSP and its consolidated subsidiaries, and NSP reports, in its consolidated
     financial  statements:  (i)  the  revenues  of its  wholly-owned  regulated
     natural gas interstate  pipeline  (Viking) as part of Gas Utility revenues,
     (ii) the revenues of its other consolidated  subsidiaries as part of "Other
     Income  (Deductions),"  and  (iii) the  results  of the  operations  of its

canceled and shall cease to exist,  and no  consideration  shall be delivered in
exchange therefor.  As noted previously,  NSP will change its name to Xcel at or
prior to the Merger.  Based upon the  capitalization of NCE and NSP on March 24,
1999 (the date the Merger  Agreement was signed) and the Conversion  Ratio,  NCE
shareholders  would own 54 percent and NSP shareholders  would own 46 percent of
the common equity of Xcel if the Merger had been consummated as of such date.

----------
14   Each NCE Right  entitles  the  registered  holder to purchase  from NCE one
     one-hundredth of a share of Series A Junior Participating  Preferred Stock.
     The NCE Rights were distributed as a dividend on each outstanding  share of
     NCE  Common  Stock as part of  NCE's  shareholder  rights  plan  which  was
     approved by the Commission in New Century Energies, Holding Co. Act Release
     No. 26751 (Aug. 1, 1997).

----------

     Except as set forth  below,  if any  holder of NCE  Common  Stock  would be
entitled  to  receive a number of shares of NSP  Common  Stock  that  includes a
fraction,  then in lieu of a fractional  share,  such holder will be entitled to
receive a cash payment  determined by multiplying the fractional  share interest
by the average of the last reported  sales price,  regular way, per share of NSP
Common Stock on the NYSE  Composite  Tape for the ten business days prior to and
including  the last  business  day on which NSP  Common  Stock was traded on the
NYSE,  without any interest thereon.  Fractional shares of NCE Common Stock held
in accounts under the dividend  reinvestment plans and employee benefit plans of
NCE will be  converted  into the  applicable  number  of shares  (or  fractional
shares) of NSP Common Stock under corresponding plans of NSP, in accordance with
the Conversion Ratio.

     The  Merger is subject  to  customary  closing  conditions,  including  the
receipt of the requisite  shareholder approvals of NCE and NSP and all necessary
governmental approvals, including the approval of the Commission.

     The  Merger is  designed  to qualify  as a  tax-free  reorganization  under
Section  368(a) of the Internal  Revenue Code of 1986,  as amended.  NSP and NCE
believe the Merger will be treated as a "pooling of  interests"  for  accounting
purposes  and, as a condition  under the Merger  Agreement to the closing of the
Merger, each of NSP and NCE must receive a letter of its independent accountants
stating in  substance  that it is  appropriate  to  account  for the Merger as a
pooling of interests under Opinion 16 of the Accounting Principles Board.

     The Merger Agreement  contains certain covenants relating to the conduct of
business by the parties pending the consummation of the Merger.  Generally,  the
parties must carry on their  businesses in the ordinary  course  consistent with
past practice,  may not increase common stock dividends  beyond specified levels
and may not issue capital stock except as specified.  The Merger  Agreement also
contains  restrictions  on, among other  things,  charter and bylaw  amendments,
capital expenditures,  acquisitions,  dispositions,  incurrence of indebtedness,
certain increases in employee compensation and benefits, and affiliate Mergers.

     The Merger Agreement  provides that, after the effectiveness of the Merger,
Xcel's  principal  corporate  office will be located in Minneapolis,  Minnesota.
Xcel will also  maintain  significant  operating  offices in  Denver,  Colorado;
Amarillo,  Texas;  and  Eau  Claire,   Wisconsin.   Xcel's  board  of  directors
(classified  into three  classes)  will  consist  of an even  number of up to 14
persons,  half  of whom  will be  designated  by NSP  and  half of whom  will be
designated by NCE. Mr. James J. Howard,  the current  Chairman,  Chief Executive
Officer and President of NSP, will be entitled to serve as Chairman of the Board
of Xcel until the first  anniversary of the  effectiveness  of the Merger of NCE
and NSP.  Mr. Wayne H.  Brunetti,  the  Chairman,  Chief  Executive  Officer and
President  of NCE,  will be entitled to serve as President  and Chief  Executive
Officer of Xcel upon the effectiveness of the Merger, and thereafter will assume
the position of Chairman when Mr.  Howard ceases to be Chairman.  The balance of
the Xcel  executive  management is expected to consist of current  executives of
NCE  and NSP as  follows:  Paul  Bonavia  (currently  NCE  General  Counsel  and
President  -  International  Business),  Head  of  Energy  Markets;  Dick  Kelly
(currently NCE Executive Vice President and Chief  Financial  Officer),  Head of
Corporate  Development  and  Strategy/Unregulated   Subsidiaries;  Gary  Johnson
(currently  NSP Senior Vice  President and General  Counsel),  General  Counsel;
Cyndi  Lesher  (currently  NSP  President  -  Gas  Utility  Operations),   Chief
Administrative  Officer; James McIntyre (currently NSP Senior Vice President and
Chief Financial Officer),  Chief Financial Officer;  Toni Petillo (currently NCE
President - Retail Services), Head of Retail Operations; Larry Taylor (currently
NSP President - Delivery  Services),  Head of Energy  Delivery;  and David Wilks
(currently SPS President and Head of the Delivery Business Unit), Head of Energy
Supply.

E.   Operations of the Combined Company

     As explained more fully in Item  3.C.1(b),  the gas operations of Xcel will
constitute a single,  integrated gas-utility system, and the electric operations
(with the exception of Cheyenne,  which the Commission has already found to be a
permissible  additional  system)  will  similarly  form  a  single,   integrated
electric-utility  system.  There will be significant  savings and synergies as a
result of these integrated  operations.  As noted previously and as described in
Item 3.C.2 below,  the  benefits  are  estimated to exceed $1.1 billion over the
next ten years.

Item 2.  Fees, Commissions and Expenses

     The fees,  commissions  and  expenses to be paid or  incurred,  directly or
indirectly,  in  connection  with the  Merger,  including  the  solicitation  of
proxies,  registration  of securities of Xcel under the  Securities Act of 1933,
and other related matters, are estimated as follows:

Commission filing fee for the Joint Registration Statement
on Form S-4........................................................$1,145,707.50

A.   Merger Analysis -- Overview

     1.   Introduction

     The Commission must find that Section 10 of the Act is satisfied to approve
the Merger.  The Section 10 analysis is presented in detail below. The highlight
of the  analysis is whether the Merger will tend toward the  economical  and the
efficient development of an integrated public utility system. Applicants believe
that it will.

     The future of the electric utility industry will be much different from its
past.  The utility market model,  with  generation  functionally  unbundled from
transmission and distribution, is supplanting the vertically integrated monopoly
model.  Applicants  recognize these changes and believe that the Merger forms an
integrated  public  utility  system  positioned  for  competition in the utility
industry  of the future.  FERC's  Order No. 888 and its recent  Order No.  2000,
described  below,  will  further the  development  of the market model by making
transmission access available on a regional basis at non-pancaked rates, thereby
promoting the growth of larger and more  competitive  regional  wholesale  power
markets.  More buyers and sellers participate in broader bulk power markets, and
this increased  competition will tend to produce lower prices for the benefit of
consumers.  As these markets expand,  opportunities  also expand for integration
between what were previously viewed as distant utilities.  For example,  the NSP
companies and SPS are presently located to the north and south, respectively, of
the  Midwest  Independent  System  Operator,   Inc.  ("MISO"),  a  FERC-approved
independent system operator.  Pursuant to FERC directives as part of the Merger,
they will join MISO,  increasing its regional market size and competition within
bulk  power  markets.  Moreover,  PSCo  and  SPS  continue  to work  toward  the
completion  of a  physical  interconnection  to link  their  systems,  and PSCo,
consistent  with FERC policy,  is working with its neighbors to establish an ISO
in the Rocky Mountain/High Plains region, which would neighbor MISO.

     The 1935 Act was intended,  among other  things,  to prevent the evils that
arise "when the growth and extension of holding  companies  bears no relation to
the economy of management and operation or the integration  and  coordination of
related  operating  properties . . ."/15  In  contrast,  the Xcel  system  is an
example of growth that promotes  economies and coordination of related operating
properties  within a single  region in a manner  consistent  not only  under the
policies  of the Act,  but also with the  policies  of both FERC and with  state
regulatory  initiatives.  For these reasons,  the Merger should be authorized by
this Commission.

----------
15   Section 1(b)(4).

----------

     Section by Section Analysis

     2.   Section 9(a)(2)

     Section 9(a)(2) makes it unlawful, without approval of the Commission under
Section 10, "for any person...to acquire,  directly or indirectly,  any security
of any public-utility  company, if such person is an affiliate...of such company
and of any other  public-utility  or holding company,  or will by virtue of such
acquisition become such an affiliate." Under the definition set forth in Section
2(a)(11),  an "affiliate" of a specified company means "any person that directly
or indirectly owns, controls,  or holds with power to vote, 5 per centum or more
of the  outstanding  voting  securities  of such  specified  company,"  and "any
company 5 per centum or more of whose  outstanding  voting securities are owned,
controlled,  or held  with  power  to  vote,  directly  or  indirectly,  by such
specified company." As a result of the proposed Merger, Xcel will acquire all of
the  outstanding  voting  securities  of the NCE  Operating  Companies.  Also in
connection with the Merger, Xcel will acquire all of the outstanding  securities
of New NSP. The Merger therefore  requires prior  Commission  approval under the
standards of Section 10./16 In this regard, the relevant standards are set forth
in Sections 10(b), 10(c) and 10(f) of the Act.

----------
16   Similarly,  to the  extent  that  NCE  could  be  deemed  to  sell  utility
     securities or assets, it would require approval under Section 12.

----------

     As set  forth  more  fully  below,  the  Merger  complies  with  all of the
applicable  provisions  of Section 10 of the Act and should be  approved  by the
Commission. Thus:

     o    the consideration to be paid in the Merger is fair and reasonable;

     o    the  Merger  will not create  detrimental  interlocking  relations  or
          concentration of control;

     o    the Merger will not result in an unduly complicated  capital structure
          for the Xcel system;

     o    the Merger is in the public  interest  and the  interests of investors
          and consumers;

     o    the  Merger  is  consistent  with  Section  8 and not  detrimental  to
          carrying out the provisions of Section 11 of the Act;

     o    the Merger tends toward the  economical  and efficient  development of
          both integrated electric and gas systems; and

     o    the Merger will comply with all applicable state laws.

Furthermore,  the Merger also  provides an  opportunity  for the  Commission  to
follow  certain of the  interpretive  recommendations  made by the  Division  of
Investment  Management  (the "Staff") in its report issued in June 1995 entitled
"The  Regulation of Public Utility Holding  Companies"  (the "1995 Report"),  in
particular  the  Staff's   overall   recommendation   that  the  Commission  act
administratively  to  modernize  and simplify  holding  company  regulation  and
minimize  regulatory  overlap,  while  protecting the interests of consumers and
investors.

B.   Section 10(b)

     Section  10(b)  provides  that,  if the  requirements  of Section 10(f) are
satisfied, the Commission shall approve an acquisition under Section 9(a) unless
the Commission finds that:

          (1) such acquisition will tend towards  interlocking  relations or the
     concentration of control of  public-utility  companies,  of a kind or to an
     extent  detrimental to the public interest or the interests of investors or
     consumers;

          (2) in case of the  acquisition of securities or utility  assets,  the
     consideration,  including all fees, commissions, and other remuneration, to
     whomsoever  paid, to be given,  directly or indirectly,  in connection with
     such  acquisition is not reasonable or does not bear a fair relation to the
     sums  invested  in or the  earning  capacity  of the  utility  assets to be
     acquired or the utility assets underlying the securities to be acquired; or

          (3) such acquisition will unduly  complicate the capital  structure of
     the  holding-company  system of the applicant or will be detrimental to the
     public  interest or the  interests  of investors or consumers or the proper
     functioning of such holding-company system.

     1.   Section 10(b)(1)

     The standards of Section 10(b)(1) are satisfied because the proposed Merger
will not "tend towards interlocking relations or the concentration of control of
public utility  companies,  of a kind or to an extent  detrimental to the public
interest or the interests of investors or consumers." By its nature,  any merger
results in new links between previously unrelated companies.  The Commission has
recognized that such interlocking  relationships are permissible in the interest
of efficiencies and economies.  Northeast Utilities, Holding Co. Act Release No.
25221 (Dec. 21, 1990), as modified,  Holding Co. Act Release No. 25273 (Mar. 15,
1991),  aff'd sub nom.  City of Holyoke v. SEC,  972 F.2d 358 (D.C.  Cir.  1992)
("interlocking  relationships  are  necessary  to  integrate  [the  two  merging
entities]").  The links that will be  established  as a result of the Merger are
not the types of interlocking  relationships targeted by Section 10(b)(1), which
was primarily aimed at preventing business  combinations  unrelated to operating
synergies.  The Merger Agreement  provides for the Board of Directors of Xcel to
consist of up to 14 members,  one-half designated by NSP and one-half designated
by  NCE./17  In  addition,  a  variety  of  contractual  arrangements  among the
companies in the Xcel system will be established, including the following:

----------
17   The Applicants acknowledge the requirements of Section 17(c) of the Act and
     Rule 70 thereunder with respect to limitations  upon directors and officers
     of registered  holding  companies and subsidiary  companies  thereof having
     affiliations with commercial  banking  institutions and investment  bankers
     and  undertake  that,  upon  completion  of the  Merger,  they  will  be in
     compliance with the applicable provisions thereof.

----------

     o    New NSP and NSP-W will each enter into the Utility  Service  Agreement
          with  New  Century  Services.  Likewise,  NSP's  direct  and  indirect
          non-utility  subsidiaries  will  enter  into the  Non-Utility  Service
          Agreement  with New Century  Services.  Through the  consolidation  of
          functions  into New Century  Services,  the Xcel  system will  achieve
          substantial economies and efficiencies. By entering into these service
          agreements,  NSP and its direct and indirect subsidiaries will receive
          services from New Century Services and effectively avail themselves of
          these  economies and  efficiencies,  just as the NCE system  companies
          presently do.

     o    New NSP and NSP-W may  enter  into  service  agreements  with  Utility
          Engineering,  Inc.  ("UE")  to  obtain  engineering  and  construction
          services.  UE was  authorized to provide the NCE  Operating  Companies
          such services in the 1997 NCE Order. These arrangements  should enable
          New NSP and NSP-W to  achieve  further  efficiencies,  just as the NCE
          Operating Companies have.

     o    New  NSP,  NSP-W,  PSCo  and SPS  will  enter  into a Joint  Operating
          Agreement  (the  "Joint  Operating  Agreement"),  which  provides  for
          coordinated  operation  and  dispatch  of  their  electric  generation
          plants, joint planning and coordinated  production-related  activities
          including  inter-system  sales of electric  capacity and energy.  This
          agreement,  which has been approved by FERC conditioned only on Merger
          closing, is discussed further below.

     o    New  NSP,  NSP-W,  PSCo,  SPS and  Cheyenne  will  enter  into a joint
          open-access  transmission tariff (the "Xcel Tariff") pursuant to which
          they will offer  transmission  services over their individual  systems
          and over the combined  Xcel system.  This tariff has been  approved by
          FERC conditioned only on Merger closing.

These  arrangements,  which work to integrate  NSP and NCE into the Xcel system,
will be in the public  interest  and the interest of  investors  and  consumers.
Forging such  relationships  is beneficial to the protected  interests under the
Act  and,  thus,  is not  prohibited  by  Section  10(b)(1).  Moreover,  because
substantial benefits will accrue to the public, investors and consumers from the
combination of NCE and NSP, whatever  interlocking  relationships may arise from
the combination are not detrimental.

     In applying Section 10(b)(1) to utility  acquisitions,  the Commission must
further  determine  whether the acquisition  will create "the type of structures
and  combinations at which the Act was  specifically  directed."  Vermont Yankee
Nuclear  Power  Corp.,  Holding Co. Act Release No.  15958 (Feb.  6, 1968).  The
NSP-NCE  strategic  alliance  will not create a "huge,  complex  and  irrational
system" but, rather,  will afford the opportunity to achieve  economies of scale
and  efficiencies  for the benefit of  investors  and  consumers.  See  American
Electric Power Company,  Inc., Holding Co. Act Release No. 20633 (July 21, 1978)
("AEP"). As explained in the Joint Proxy Statement and Prospectus of NSP and NCE
(the "Joint Proxy  Statement") (a copy of which is included as Exhibit C-2), the
primary  objective of the Merger is to position the companies to  participate in
the growing and  increasingly  competitive  energy  markets.  Specifically,  the
Merger will combine the  strengths of the two  companies,  thus enabling them to
offer customers a broader array of energy products and services more efficiently
and  cost-effectively  than could either company  acting alone,  and at the same
time create a larger and more diverse  asset and customer  base,  with  enhanced
opportunities for operating efficiencies and risk diversification.  Xcel will be
a mid-size  registered  holding company,  and its operations will not exceed the
economies of scale of current electric generation and transmission technology or
provide  undue  market  power or  control to Xcel in the region in which it will
provide service.

     While  the  combination  of NCE and NSP will  result  in a  larger  utility
system,  it  certainly  will not be one that  exceeds the  economies of scale of
current electric  generation and transmission  technology,  on the one hand, and
gas  transportation  technology on the other. If approved,  the Xcel system will
serve approximately 3.0 million electric customers and 1.5 million gas customers
in twelve  states.  As of December  31,  1999 and June 30,  2000,  the  combined
consolidated  assets of the Applicants totaled  approximately  $18.0 billion and
$20.2 billion, respectively,  and, for the twelve months ended December 31, 1999
and June 30,  2000,  combined  operating  revenues  totaled  approximately  $6.9
billion and $7.8 billion,  respectively.  As of December 31, 1999,  the combined
owned summer  generating  capacity of the regulated  utility  operations of NSP,
NSP-W, PSCo and SPS totaled approximately 15,170 MW.

     The following  table shows the Xcel  system's  relative size as compared to
other   registered   systems  in  terms  of  assets,   operating   revenues  and
customers/18:

              Total Assets         Operating Revenues        Electric Customers
  System      ($ Millions)            ($ Millions)              (Thousands)
  ------      ------------            ------------              -----------
Southern         $38,396                $11,585                     3,871
AEP               21,488                  6,315                     3,017
Entergy           22,985                  8,773                     2,522
CSW               14,162                  5,537                     1,763
GPU               21,718                  4,757                     2,063
Xcel              20,228                  7,792                     3,000


     Based on publicly available similar information/19 as of December 31, 1998,
NCE ranked as the 25th largest system in terms of electric  operating  revenues,
the 30th largest  system in terms of total assets and the 22nd largest system in
terms of U.S.  electric  customers.  NSP meanwhile  ranked as the 27th, 31st and
21st such largest  systems.  The Xcel  combined  system would have ranked as the
10th largest system in terms of electric  operating  revenues,  the 13th largest
system  in terms of total  assets  and the 8th  largest  system in terms of U.S.
electric  customers,  and would account for less than 3.5% of the total share of
all investor owned utilities.  Thus, the data clearly shows that there will be a
number of larger  utility  systems,  including  several  combinations  that have
recently been approved by the Commission.

     Moreover,  the Commission has approved a number of  acquisitions  involving
larger and  similarly-sized  operating  utilities.  See, e.g., American Electric
Power Company,  Inc.,  Holding Co. Act Release No. 27186 (June 14, 2000) (herein
the  "AEP/CSW  Order")  (acquisition  of  Central  and South  West  Corporation;
combined  assets at  anticipated  time of  closing  in  excess of $35  billion);
Entergy  Corporation,  Holding  Co.  Act  Release  No.  25952  (Dec.  17,  1993)
(acquisition of Gulf States Utilities; combined assets at time of acquisition in
excess of $22 billion);  TUC Holding Company,  Holding Co. Act Release No. 26749
(Aug. 1, 1997) (combination of Texas Utilities Company and ENSERCH  Corporation;
combined  assets at time of acquisition of $24.0  billion);  Houston  Industries
Incorporated,  Holding Co. Act Release No. 26744 (July 24, 1997) (combination of
Houston Industries  Incorporated and NorAm Energy Corp., combined assets at time
of acquisition of $16.0 billion);  Northeast  Utilities,  supra  (acquisition of
Public Service Company of New Hampshire;  combined assets at time of acquisition
of  approximately $9 billion);  Centerior Energy Corp.,  Holding Co. Act Release
No. 24073 (April 29, 1986) (combination of Cleveland  Electric  Illuminating and
Toledo Edison;  combined  assets at time of acquisition  of  approximately  $9.1
billion);  AEP,  supra  (acquisition  of Columbus  and Southern  Ohio  Electric;
combined assets at time of acquisition of close to $9 billion).  Furthermore, at
a time of  consolidation  in the industry,  the combined  assets of Xcel will be
less than the combined assets of certain existing  registered holding companies:
AEP ($19.4  billion at December 31, 1998),  Southern  Company  ($36.2 billion at
December 31, 1998), Entergy Corporation ($22.8 billion at December 31, 1998) and
GPU, Inc. ($16.3 billion at December 31, 1998).

     The  Commission  has  rejected a mechanical  size  analysis  under  Section
10(b)(1) in favor of assessing the size of the resulting  system with  reference
to the economic  efficiencies  that can be achieved  through the integration and
coordination of utility operations. See, e.g., AEP, supra. The Commission in AEP
noted that,  although the framers of the Act were concerned  about "the evils of
bigness,  they were also aware that the  combination of isolated local utilities
into an integrated  system afforded  opportunities  for economies of scale,  the
elimination of duplicate  facilities and  activities,  the sharing of production
capacity and reserves and generally  more  efficient  operations...[and]  [t]hey
wished to preserve these  opportunities." Id. By virtue of the Merger, Xcel will
be in a position  to realize  precisely  these  types of  benefits.  Among other
things,  the Merger is  expected  to yield  labor cost  savings,  corporate  and
administrative and purchasing  savings,  cost of fuel and purchased gas savings.
These expected  economies and efficiencies from the combined utility  operations
are described in greater detail in Item 3.C.2., below.

     Finally, Section 10(b)(1) also requires the Commission to consider possible
anticompetitive  effects of a proposed  combination.  As the Commission noted in
Northeast  Utilities,  the "antitrust  ramifications  of an acquisition  must be
considered in light of the fact that public  utilities are regulated  monopolies
and that federal and state administrative agencies regulate the rates charged to
customers."  NCE and NSP have  filed  Notification  and  Report  Forms  with the
Department of Justice and the Federal Trade  Commission  pursuant to the HSR Act
describing the effects of the Merger on competition in the relevant market,  and
the applicable waiting period under the HSR Act expired on March 1, 2000.

     The  competitive  impact of the Merger was also  extensively  considered by
FERC in  unconditionally  approving the Merger. In proceedings under Section 203
of the Federal Power Act involving utility mergers, FERC, under well-established
policy,  must  evaluate  the  competitive  effects of a proposed  merger  before
deciding whether to approve the merger as "consistent with the public interest,"
the  applicable  standard of  review./20  Accordingly,  as part of their  merger
application to FERC,  Applicants  submitted the testimony of Dr.  Heironymus and
Dr.  Gilbert  submitted  in support of the FERC  application  (filed as Exhibits
D-1.1 and D-1.2 hereto),  Dr. Heironymus  analyzed the horizontal effects of the
Merger  (i.e.,  those  that  result  from  combining  the  companies  generating
resources)  and Dr.  Gilbert  analyzed the vertical  effects  (i.e.,  those that
result  from   consolidating   the   companies'   gas  delivery  and  generation
facilities).  Based on  those  analyses,  Applicants  believe  that  there is no
adverse impact on competition resulting from the consolidation of the pre-merger
market shares of  Applicants.  While  Applicants  have  acknowledged  that their
post-merger  integration plans will affect their post-merger market shares, they
explained  to FERC that these  occur as a result of  joining an RTO and  through
exercise  of rights  under FERC Order No. 888 and that they do not  reflect  any
overall anti-competitive effects of the Merger./21

----------
20   16 U.S.C.  ss.824b(a).  The  factors  that FERC  focuses on in making  this
     public  interest  determination  are set out in its Inquiry  Concerning the
     Commission's  Merger Policy Under the Federal Power Act: Policy  Statement,
     Order No. 592, 61 Fed. Reg. 68,595 (1996),  reconsideration  denied,  Order
     No. 592-A, 62 Fed. Reg. 33,341 (1997).

21   While  Applicants  have committed to certain  market  mitigation in the NSP
     destination market, this was done to allay any potential concerns about the
     impact of the Merger on competition.

----------

     The  FERC  Merger  Order  effectively  validated   Applicants'   conclusion
regarding the lack of competitive impacts.  After considering various intervenor
comments and protests,  and performing its own extensive analysis of competitive
effects,  FERC  concluded that the Merger was unlikely to have an adverse effect
on competition  (both  horizontal and vertical  analysis) and that there were no
issues  regarding  the Merger  that  warranted  a hearing.  FERC thus  summarily
approved the Merger.

     The  analysis  on which FERC based this  conclusion  relied  heavily on the
commitment of NSP and SPS to join MISO. "We find the  Applicants'  commitment to
join  the  MISO  alleviates  any  concern   regarding  the  merger's  impact  on
competition  and is  sufficient  to support  our  approval  of the  merger.  Our
approval of the merger is based on  Applicants'  participation  in the MISO."/22
FERC also  concluded  that it  believed  that the Merger did not raise  vertical
competitive  issues./23 The  Commission  has found,  and the courts have agreed,
that it may appropriately rely upon FERC with respect to such findings. See City
of Holyoke v. SEC, supra at 363-64, quoting Wisconsin's  Environmental Decade v.
SEC, 882 F.2d 523, 527 (D.C. Cir. 1989). For these reasons,  the Merger will not
"tend toward  interlocking  relations or the concentration of control" of public
utility companies, of a kind or to the extent detrimental to the public interest
or the  interests  of  investors  or  customers  within  the  meaning of Section
10(b)(1).

     2.  Section 10(b)(2)

     Section 10(b)(2)  precludes approval of an acquisition if the consideration
to be paid in connection with the combination,  including all fees,  commissions
and other  remuneration,  is "not reasonable or does not bear a fair relation to
the sums invested in or the earning capacity  of...the utility assets underlying
the securities to be acquired." The Commission has found  "persuasive  evidence"
that the standards of Section  10(b)(2) are satisfied where, as here, the agreed
consideration  for an  acquisition  is the result of  arm's-length  negotiations
between the  managements  of the  companies  involved,  supported by opinions of
financial  advisors.  See  Southern  Company,  Holding Co. Act Release No. 24579
(Feb. 12, 1988).

     First, the Merger is a pure stock-for-stock exchange that is to qualify for
treatment as a pooling of  interests./24  The Merger will  therefore  involve no
"acquisition adjustment" or other write-up of the assets of NCE or NSP.

----------
24   Twelve  specific  conditions  must be met to  qualify  for  treatment  as a
     pooling of interests. The Merger should meet those criteria as follows: (1)
     Both NSP and NCE were  autonomous  and were not a subsidiary or division of
     another  corporation  within two years before the plan of  combination  was
     initiated;  (2) at the  date of the  merger  initiation  and at the date of
     consummation  NSP and NCE are  independent  of each other;  (3) NSP and NCE
     will undertake a course of action which will attempt to complete the Merger
     within one year in  accordance  with a specific  plan,  or  completed  in a
     single transaction.  Litigation or proceedings of a governmental  authority
     that delay the  completion of a plan are excepted  from the one-year  rule,
     provided they are beyond the control of the combining companies; (4) at the
     consummation  date of the plan, NSP will offer and issue its majority class
     of stock  (voting  rights) for no less than 90% of the voting  common stock
     interests  of NCE.  The 90% or more of the voting  common  stock  interests
     being  acquired is determined at the date the plan is  consummated;  (5) no
     changes in the equity  interests  of the voting  common stock of NSP or NCE
     were  to  be  made  in  contemplation  of a  pooling  of  interests  ("this
     restriction  is for a period  beginning  two years prior to the  initiation
     date of the plan of  combination  and for the period between the initiation
     date and the consummation  date); (6) NSP and NCE will not reacquire any of
     its  voting  common  stock  in  substance  or form  to  effect  a  business
     combination  ("any  reacquisition  must be a normal  amount as evidenced by
     both companies'  patterns of reacquisition  prior to the merger";  (7) each
     NSP and NCE common  stockholder will receive a voting common stock interest
     exactly in proportion to his or her voting common stock  interest  prior to
     the combination;  (8) the NSP and NCE common  shareholders will receive the
     rights they are entitled to and will not be deprived or  restricted  in any
     way from exercising those rights;  (9) the entire merger agreement will not
     be effected on the date of consummation; (10) subsequent to consummation of
     the  merger,  NSP will not agree to  reacquire  or retire  any of the stock
     which was  issued to effect  the  Merger;  (11) NSP will not enter into any
     agreements to the benefit of the former shareholders of NSP or NCE, such as
     loan  guarantees;  and (12) NSP will  not plan to  dispose  of  substantial
     amounts  of  assets  of NSP or NCE  within  two  years  of the  date of the
     combination  other than  routine  transactions  in the  ordinary  course of
     business or to eliminate excess capacity.

----------

     Second,  as  explained  on pages  41 and 47 of the  Joint  Proxy  Statement
(EXHIBIT C-2 hereto),  the historical  price data, high and low, for NSP and NCE
Common Stock provide support for the  consideration of 1.55 shares of NSP Common
Stock for each share of NCE Common Stock.

     Third,  the  Conversion  Ratio is the  product of  extensive  and  vigorous
arm's-length  negotiations between NCE and NSP. These negotiations were preceded
by extensive due diligence,  analysis and evaluation of the assets,  liabilities
and business  prospects  of each of the  respective  companies.  This process is
described  in  "Background  of the  Merger" at pages 30 to 35 of the Joint Proxy
Statement.  As recognized by the  Commission in Ohio Power Co.,  Holding Co. Act
Release  No.  16753  (June 8,  1970),  prices  arrived at  through  arm's-length
negotiations  are  particularly  persuasive  evidence  that Section  10(b)(2) is
satisfied.

     Fourth,  nationally-recognized  investment  bankers  for NCE  and NSP  have
reviewed extensive information concerning the companies, analyzed the Conversion
Ratio  employing  a variety  of  valuation  methodologies  and  opined  that the
Conversion  Ratio is fair to the respective  holders of NCE Common Stock and NSP
Common Stock as of the date of the Merger Agreement and as of the date the Joint
Proxy  Statement  was  mailed to  stockholders  of NSP and NCE.  The  investment
bankers'  analyses and opinions are described in detail on pages 40 to 53 of the
Joint Proxy  Statement.  The  assistance of  independent  consultants in setting
considerations  has been  recognized  by the  Commission  as  evidence  that the
requirements of Section 10(b)(2) have been met. Southern Company, supra.

     Finally,  the Merger was submitted to, and approved by, the affected public
shareholders,  i.e., the common shareholders of NCE and the common and preferred
shareholders  of  NSP.  Holders  of  approximately  93% of  NCE's  common  stock
represented at the meeting approved the Merger, and holders of approximately 83%
of NSP's common and  preferred  stock  represented  at the meeting  approved the
Merger.

     A  further  consideration  under  Section  10(b)(2)  is the  overall  fees,
commissions and expenses to be incurred in connection  with the Merger.  NCE and
NSP believe  that these items are  reasonable  and fair in light of the size and
complexity of the Merger relative to other utility mergers and acquisitions, and
the  anticipated  benefits of the Merger to the public,  investors and consumers
are consistent with recent precedent and meet the standards of Section 10(b)(2).

     As set  forth  in  Item 2 of  this  Application-Declaration,  NSP  and  NCE
together  expect to incur a combined  total of  approximately  $43.7  million in
fees,  commissions  and expenses in  connection  with the Merger,  including the
financial advisory fees to SG Barr Devlin and The Blackstone Group. By contrast,
the total  transaction fees and regulatory  processing fees in the AEP/CSW Order
were approximately $73 million.  The Cincinnati Gas and Electric Company and PSI
Resources   incurred   $47.12   million  in  fees  in   connection   with  their
reorganization  as subsidiaries of CINergy;  Northeast  Utilities alone incurred
$46.5 million in fees and expenses in connection  with its acquisition of Public
Service of New  Hampshire;  and Entergy  alone  incurred  $38 million in fees in
connection  with its  acquisition of Gulf States  Utilities -- which amounts all
were approved as reasonable by the Commission.  CINergy, Holding Co. Act Release
No. 26146 (Oct.  21,  1994);  Northeast  Utilities,  Holding Co. Act Release No.
25548 (June 3, 1992); and Entergy Corp., Holding Co. Act Release No. 25952 (Dec.
17, 1993).

     The Applicants  believe that the estimated fees and expenses in this matter
bear a fair relation to the value of their respective companies and the benefits
to be achieved by the Merger,  and further  that the fees and  expenses are fair
and  reasonable  in  light  of the  complexity  of  the  Merger.  See  Northeast
Utilities, supra (noting that fees and expenses must constitute normal costs and
represent a minor part of the overall  acquisition).  Based on a $20.1875  price
per share of NSP Common Stock, which was the closing price per share as reported
on the NYSE-Composite  Transaction of NSP Common Stock June 30, 2000, the Merger
would be valued at  approximately  $3.7 billion.  The total  estimated  fees and
expenses  of $52  million  represent  approximately  1.4%  of the  value  of the
consideration  to be paid, and are consistent  with (or lower than)  percentages
previously approved by the Commission. See, e.g., Entergy Corp., supra (fees and
expenses  represented  approximately 1.7% of the value of the consideration paid
to the shareholders of Gulf States Utilities);  Northeast Utilities, supra (fees
and  expenses  represented  approximately  2% of the  value of the  assets to be
acquired);  AEP/CSW Order (fees and expenses  represented  approximately 1.1% of
the value of the consideration paid by AEP).

     3.  Section 10(b)(3)

     Section  10(b)(3)  requires the Commission to determine  whether the Merger
will "unduly  complicate the capital structure" or be "detrimental to the public
interest or the interest of investors or consumers or the proper functioning" of
the Xcel system.

     The  capital  structure  of Xcel will be  substantially  similar to capital
structures  approved  by the  Commission  in other  orders.  See,  e.g.,  Ameren
Corporation,  Holding Co. Act Release No. 26809 (Dec.  30, 1997);  CINergy Corp;
Holding Co. Act Release No. 26934 (Nov. 2, 1998);  and  Centerior  Energy Corp.,
Holding Co. Act Release No. 24073 (April 29,  1986).  Xcel's  capital  structure
will also be similar to the capital  structures of existing  registered  holding
company  systems.  See, e.g.,  Ameren,  supra;  the 1997 NCE Order,  supra;  and
American Electric Power,  Holding Co. Act Release No. 21433 (Feb. 13, 1980). The
shareholders  of NCE will receive Xcel (i.e.,  NSP) Common Stock.  Xcel will own
100% of the common stock of NSP-W,  New NSP, BMG,  SPS,  PSCo and Cheyenne,  and
there will be no minority common stock interest in any of those companies.  Each
outstanding share of NSP preferred stock will remain outstanding  without change
as  preferred  stock of Xcel.  The  Commission  has  found  previously  that the
existence  of preferred  stock under facts  similar to those of the present case
does not violate the standards of the Act.  Illinois Power Company,  Holding Co.
Act Release No. 16574 (Jan. 2, 1970)  (finding that  "adequate  safeguards  were
afforded  by the  dividend  and  liquidation  preferences  and other  protective
provisions that are applicable to such stock).  See also, New Century  Energies,
Inc.,  Holding Co. Act  Release No.  26751(Aug.  1, 1997) and The  Columbia  Gas
System,  Inc.,  Holding  Co.  Act  Release  No.  26361  (Aug.  25,  1995)  (each
authorizing preferred stock in a registered holding company).

     The existing  debt  securities of NSP,  NSP-W,  SPS, PSCo and Cheyenne will
likewise remain outstanding without change,  except that, with the merger of NCE
into NSP, the debt of NCE will become the debt of Xcel, and the existing debt of
NSP will be transferred to New NSP. The only voting securities of Xcel that will
be publicly held after the Merger will be NSP's existing Preferred Stock (which,
as noted above,  will become Preferred Stock of Xcel) and Xcel Common Stock. The
outstanding  NSP  (i.e.,  Xcel)  preferred  stock will  consist of 1.05  million
shares,  consisting of 6 series.  Each share of such preferred stock is entitled
to one  vote  per  share  on all  matters  presented  to  stockholders  with the
exception of $3.60 series  consisting  of 275,000  shares,  which is entitled to
three votes per share./25

----------
25   This  Application  only  requests  authorization  to retain such  preferred
     stock.  Any  proposed  issuance  of  additional  preferred  stock  will  be
     addressed in a separate application.

----------

     Xcel will  have the  ability  to  issue,  subject  to the  approval  of the
Commission,  preferred  stock,  the terms of which may be set by Xcel's Board of
Directors.  See, e.g.,  Columbia Gas System,  Inc.,  Holding Co. Act Release No.
26361 (Aug. 25, 1995) (approving restated charter, including preferred the terms
of  which,  including  voting  rights,  can  be  established  by  the  board  of
directors).  The only  outstanding  class of voting  securities of Xcel's direct
non-utility  subsidiaries will be common stock and, in each case, all issued and
outstanding  shares of such  common  stock will be held by Xcel  (other  than as
noted above for C&F, which is 75.86% owned;  NMC,  which is 25% owned;  and NRG,
which is 82% owned.)

     Set forth below are  summaries of the capital  structures of NSP and NCE as
of December 31, 1999, and the pro forma  consolidated  capital structure of Xcel
(assuming the Merger occurred on June 30, 2000):

Xcel's pro forma  consolidated  common equity to total  capitalization  ratio of
38.8% as of  December  31,  1999,  and 36.0% as of June 30,  2000,  exceeds  the
"traditionally  acceptable 30% level."/26 Northeast  Utilities,  Holding Co. Act
Release No. 25221 (Dec.  21, 1990).  Accordingly,  the proposed  Merger will not
unduly complicate the capital structure of the resulting holding company.

----------
26   Under section  7(d)(1) of the Act, the Commission  generally has required a
     registered  holding company system and its  public-utility  subsidiaries to
     maintain a 65/30  debt/common  equity ratio,  the balance  generally  being
     preferred equity. Such debt/equity  capitalization requirement was included
     in rule 52, as  originally  adopted,  as  applied to  securities  issued by
     public-utility subsidiaries, but was eliminated in 1992.

----------

     Section  10(b)(3)  also requires the  Commission  to determine  whether the
proposed  combination will be detrimental to the public interest,  the interests
of investors or consumers or the proper functioning of the combined Xcel system.
The  combination  of  NSP  and  NCE  is  entirely  consistent  with  the  proper
functioning  of a registered  holding  company  system.  NSP's and NCE's utility
operations will be fully  integrated.  Further,  the combination  will result in
substantial,  otherwise  unavailable,  savings and benefits to the public and to
consumers and investors of both  companies,  and the  integration of NSP and NCE
will improve the efficiency of their respective systems.  The integration of NSP
and NCE is described  below in Item  3.C.1.(b)  and the benefits and savings are
described in Item 3.C.2.

     Finally, as indicated previously, consummation of the Merger is conditional
upon  receipt  of  numerous  state  and  federal  regulatory  approvals.   These
regulatory  approvals  will assure that the  interests of retail  customers  and
wholesale  customers are adequately  protected.  FERC's recent approval  further
assures that there will be no significant  effect to competition  resulting from
the  Merger.  Moreover,  as  noted  by the  Commission  in  approving  Entergy's
acquisition  of Gulf States  Utilities,  "concerns  with  respect to  investors'
interests have been largely addressed by developments in the federal  securities
laws and the  securities  market  themselves."  Entergy  Corp.,  Holding Co. Act
Release No. 25952 (Dec. 17, 1993).  Xcel, New NSP, NSP-W, PSCo, SPS and NRG will
be reporting companies subject to the continuous disclosure  requirements of the
1934 Act following the completion of the Merger.  The various reports previously
filed by NSP and NCE under the 1934 Act contain  readily  available  information
concerning the Merger. For these reasons, the Applicants believe that the Merger
will be in the public  interest and the interest of investors  and consumers and
will not be  detrimental  to the proper  functioning  of the  resulting  holding
company system.

C.   Section 10(c)

     Section 10(c) of the Act provides that,  notwithstanding  the provisions of
Section 10(b), the Commission shall not approve:

     (1) an  acquisition  of  securities  or  utility  assets,  or of any  other
     interest,  which is  unlawful  under  the  provisions  of  Section  8 or is
     detrimental to the carrying out of the provisions of Section 11; or

     (2) the  acquisition of securities or utility assets of a public utility or
     holding  company unless the  Commission  finds that such  acquisition  will
     serve the  public  interest  by  tending  towards  the  economical  and the
     efficient development of an integrated public utility system.

     1.  Section 10(c)(1)

          (a)  The Merger will be lawful under Section 8

     Section  10(c)(1) first requires that the Merger be lawful under Section 8.
That section was intended to prevent holding  companies,  by the use of separate
subsidiaries,  from circumventing  state restrictions on common ownership of gas
and electric  operations.  The Merger will not result in any new  situations  of
common  ownership  of  so-called  "combination"  systems  within a given  state.
Post-Merger, New NSP, as successor to NSP, will continue to provide electric and
gas utility  services in Minnesota,  North Dakota and South  Dakota.  NSP-W will
provide  electric and gas utility  services in Wisconsin and Michigan;  BMG will
provide gas and propane  service in Arizona;  PSCo will provide gas and electric
utility service in Colorado;  and Cheyenne will provide gas and electric utility
service in Wyoming. Since Minnesota,  Michigan,  Wisconsin,  Wyoming,  Colorado,
South  Dakota  and North  Dakota  law all permit  combination  gas and  electric
utilities  serving  the same  area,  the Merger  does not raise any issue  under
Section 8 or, accordingly, the first clause of Section 10(c)(1).

          (b)  The Merger will not be detrimental to carrying out the provisions
               of Section 11

     Section  10(c)(1) also requires that the Merger not be  "detrimental to the
carrying out of the  provisions  of Section 11."  Section  11(b)(1)  directs the
Commission  generally  to  limit  a  registered  holding  company  "to a  single
integrated  public-utility  system." In the 1997 NCE Order, the Commission found
that the combined  Colorado,  New Mexico,  Texas,  Oklahoma and Kansas  electric
operations  constituted  a  single,  integrated  electric  utility  system  (the
"Primary  System"),/27 and that the Wyoming  electric  operations (the "Cheyenne
Electric System") and the combined Wyoming and Colorado gas operations (the "Gas
System")  were each a permissible  additional  system under the A-B-C clauses of
Section  11(b)(1).  At issue is whether the  further  addition of NSP and NSP-W,
each of which is a combination electric and gas utility, will result in a system
that is "detrimental to the carrying out of the provisions of Section 11."

     In the  early  years  of its  administration  of the  Act,  the  Commission
construed  Section  11(b)(1) to preclude  significant  geographic  expansion  by
holding company systems.  However,  as the Commission has acknowledged,  the Act
"creates a system of pervasive and continuing  economic  regulation that must in
some measure at least be fashioned  from time to time to keep pace with changing
economic and regulatory  climates."/28 In recent  decisions,  the Commission has
cited U.S.  Supreme Court and Circuit Court of Appeals cases that recognize that
an agency is not required to  "establish  rules of conduct to last  forever,"/29
but  must  "adapt   [its]  rules  and   policies  to  the  demands  of  changing
circumstances"/30 and to "treat experience not as a jailer but as a teacher."/31
Consequently,   the  Commission  has  attempted  to  "respond  flexibly  to  the
legislative,  regulatory and  technological  changes that are  transforming  the
structure and shape of the utility  industry" as recommended in the Staff's 1995
Report.  Indeed, with specific reference to the integration  requirements of the
Act, the 1995 Report explains:

     The  statute  recognizes  . . . that  the  application  of the  integration
     standards  must be able to adjust in  response  to changes in "the state of
     the art." As  discussed  previously,  the  Division  believes  the SEC must
     respond  realistically to the changes in the utility industry and interpret
     more flexibly each piece of the integration equation./32

     Moreover,  the ultimate determination has always been whether, on the facts
of a given matter,  the proposed  transaction  "will lead to a recurrence of the
evils the Act was  intended  to  address."/33  See also  AEP/CSW  Order,  Sempra
Energy,  Holding  Company  Act Release No.  26971 (Feb.  1, 1999),  in which the
Commission  acknowledged  that "we have taken notice of  developments  that have
occurred in the gas industry, and have interpreted the Act and analyzed proposed
transactions in light of these changed and changing circumstances."/34

----------
27   The Commission's  decision was predicated on the completion of the tie line
     between the SPS and PSCo  systems or on the parties'  otherwise  satisfying
     the requirements of section  10(c)(1).  The status of the tie line has been
     discussed above.

     As explained more fully below, the combination of the Primary System of NCE
and the electric  operations of NSP and NSP-W (the "NSP  Electric  System") will
result in a single,  integrated  electric  utility  system  (the "Xcel  Electric
System").  Integration will result primarily from the Joint Operating Agreement,
which will provide the framework for the  coordinated  operation and dispatch of
the  resources of the  operating  companies of Xcel, a 100 MW firm  transmission
path from  2002  through  2004  between  SPS and the NSP  companies  which  will
facilitate  transactions  among  the Xcel  Operating  Companies  and by the Xcel
Operating  Companies  on a joint  basis  with  third  parties/35  and the common
utilization  by NSP,  NSP-W,  PSCo and SPS of New Century  Services for numerous
procurement, operational,  administrative and general services. Integration also
will be facilitated by NSP,  NSP-W and SPS joining  MISO./36 The  combination of
the NCE Gas  System  and the NSP gas  operations  also will  result in a single,
integrated  gas  utility  system  (the  "Xcel Gas  System").  Consequently,  the
Commission  should  find  that  the Xcel  Electric  System  will be the  primary
integrated  public-utility system for purposes of Section 11(b)(1), and the Xcel
Gas System and the Cheyenne  Electric System are  permissible  systems under the
A-B-C clauses of that section./37

----------
35   PSCo will be  interconnected  with the combined SPS and NSP company systems
     upon the completion of its announced tie-line with SPS.

36   In the FERC Merger  Order,  the FERC stated "Upon  joining  MISO  following
     consummation of the merger, Xcel Energy's northern zone,  consisting of New
     NSP Utility and NSP-W, will be physically  interconnected with its southern
     zone, consisting of SPS, through the transmission system of MISO."

37   The Applicants  further believe that the Commission could find (i) that the
     Xcel Gas System is the primary  integrated  system and that the NCE Primary
     System,  the Cheyenne  Electric System and the NSP Electric  Operations are
     retainable  additional  systems,  or (ii)  that the  Xcel Gas and  Electric
     Systems  together  constitute a single  integrated  public  utility  system
     within  the  meaning  of  Section  11(b)(1)  of the Act,  and the  Cheyenne
     Electric System is a retainable  additional  system. The Applicants reserve
     the right to  supplement  this  Application-Declaration  to  develop  these
     arguments  fully in the event that the  Commission  or the Staff reject the
     argument  that the Xcel  Electric  System  will be the  primary  integrated
     public-utility  system for purposes of Section  11(b)(1),  and the Xcel Gas
     System and the Cheyenne  Electric System are permissible  systems under the
     A-B-C clauses of that section.

----------

          (i)  Integration of Electric Operations

     The threshold question is whether the Primary System of NCE can be combined
with the electric  operations of NSP to form a single  integrated public utility
system. The term, as applied to electric utility companies, means:

     a system  consisting  of one or more  units  of  generating  plants  and/or
     transmission lines and/or  distributing  facilities,  whose utility assets,
     whether owned by one or more electric  utility  companies,  are  physically
     interconnected  or  capable of  physical  interconnection  and which  under
     normal conditions may be economically  operated as a single  interconnected
     and  coordinated  system  confined  in its  operations  to a single area or
     region, in one or more States,  not so large as to impair  (considering the
     state  of the art and  the  area or  region  affected)  the  advantages  of
     localized  management,   efficient  operation,  and  the  effectiveness  of
     regulation.

Section  2(a)(29)(A).  As  the  definition  suggests,  and  the  Commission  has
observed,  Section 11 is not  intended  to impose  "rigid  concepts"  but rather
creates a "flexible"  standard designed "to accommodate  changes in the electric
utility  industry."  UNITIL Corp.,  Holding Co. Act Release No. 25524 (April 24,
1992); see also Yankee Atomic  Electric.  Co., Holding Co. Act Release No. 13048
(Nov. 25, 1955) ("We think it is clear from the language of Section 2(a)(29)(A),
which defines an integrated public utility system,  that Congress did not intend
to imposed [sic] rigid concepts with respect thereto.") (citations omitted). See
also Madison Gas and Electric  Company v. SEC, 168 F.3d.  1337 (D.C.  Cir. 1999)
("section  10(c)(1) does not require that new acquisitions  comply to the letter
with section 11")./38 Section  2(a)(29)(A)  expressly  directs the Commission to
consider the "state of the art" in analyzing  the  integration  requirement.  As
indicated  above,  the  Commission  is not  constrained  by its  past  decisions
interpreting the integration  standards based on what was then the "state of the
art." See AEP, supra (noting that the state of the art -- technological advances
in  generation  and  transmission,  unavailable  thirty years prior -- served to
distinguish a prior case and justified "large systems spanning several states").

     The concept of an integrated  public utility system has evolved in light of
the dramatic changes in the law,  technology and structure of the industry since
the passage of the 1935 Act over 60 years ago.  Since the  enactment of the Act,
the "state of the art" has changed enormously, so as to include within the scope
of integrated  operations a broader range of utility  contractual  relationships
and  activities.  A review of these  changes  seems  appropriate  in view of the
Commission's  stated goal of  interpreting  the Act to reflect  and  accommodate
changes in the industry.

     Historically,  electric  utilities  have  been  single  corporate  entities
engaged in three vertically-integrated businesses: (i) generation of electricity
(i.e.,  the ownership  and operation of power plants that produce  electricity);
(ii) transmission of electricity  (i.e., the ownership and operation of the high
voltage  facilities  that  transport  electric  energy in bulk from one point to
another,  generally  from a  utility's  generating  units  to  its  distribution
facilities);  and (iii) distribution of electricity (the ownership and operation
of  the  lower  voltage   facilities  that  deliver  electric  energy  from  the
transmission  system to most end  users).  Until  recently,  electric  utilities
operated as  regulated  monopolies  "predicated  on the  concept  that a central
source  of  power   supplied  by   efficient,   low-cost   utility   generation,
transmission,  and  distribution  was a  natural  monopoly."/39 These  utilities
generally built generating  facilities in the proximity of their customers,  and
transmission was treated essentially "as an incidental service."/40

     wherein FERC described the electric industry in 1935, the year of enactment
     of both the Act and the Federal Power Act,  which was a companion  piece of
     legislation to the Act, as follows:

          The Federal Power Act was enacted in an age of mostly self-sufficient,
          vertically   integrated  electric  utilities,   in  which  generation,
          transmission,  and  distribution  facilities  were  owned  by a single
          entity  and  sold as part of a  bundled  service  (delivered  electric
          energy) to wholesale and retail  customers.  Most  electric  utilities
          built their own power plants and  transmission  systems,  entered into
          interconnection   and  coordination   arrangements   with  neighboring
          utilities,  and entered into  long-term  contracts  to make  wholesale
          requirements  sales (bundled sales of generation and  transmission) to
          municipal,  cooperative,  and other  investor-owned  utilities  (IOUs)
          connected to each utility's  transmission  system. Each system covered
          limited  service  areas.  This  structure  of separate  systems  arose
          naturally due primarily to the cost and  technological  limitations on
          the distance over which electricity could be transmitted.

          Mega-NOPR at 33,059.

----------

     In the decades following the enactment of the Act, the transmission  sector
of the electric utility industry significantly expanded. The total miles of high
voltage (230 kV and above)  transmission  lines tripled in the 1950s and tripled
again  in  the  1960s./41  Utilities  had  originally  constructed  transmission
facilities  to  transmit  power  from  their  own  plants  to  their  customers.
Subsequent to the enactment of the 1935 Act,  utilities  increasingly  developed
interconnections   with  their  neighboring  utilities  to  obtain  and  provide
assistance in emergency  situations,  to improve reliability,  and to reduce the
costs of power  supply  through  long-term  capacity  transactions  and  economy
transactions  with their  neighbors./42  Technological  advances in transmission
have also occurred,  making it possible to transmit electric power  economically
over long distances at higher voltages. In today's world, "improved transmission
and monitoring  technologies  have increased the feasible  geographic bounds for
supply  choice;  a  geographic  radius  of  1,000  miles  or more  is  currently
considered reasonable for choosing among supply options."/43

----------
41   There were 2,974 miles of high voltage transmission in 1940, 8,174 miles in
     1950,  22,379 miles in 1960,  and 65,370 miles in 1970.  Peter  Fox-Penner,
     Electric  Utility  Restructuring,  A Guide to the Competitive Era (1997) at
     130.

42   See William J. Baumol & J. Gregory Sidak, Transmission Pricing and Stranded
     Costs in the Electric Power Industry (1995) at 13.

43   Technological  advances  have  occurred  with  respect  to  the  "size"  of
     transmission  lines  (345 kV to 765 kV lines)  which have  allowed  for the
     transfer  of large  amounts of power over  great  distances.  Technological
     advances  have also  occurred  with  respect to the "type" of  transmission
     lines. High-voltage direct current ("HVDC") technology provides the ability
     to  transmit  bulk power over  longer  distances  with less energy loss and
     normally with a smaller  investment  than with  alternating  current ("AC")
     transmission   lines.  This  technology   provides  an  economical  way  to
     interconnect  separated AC power grids and enables power transfers to occur
     between  these  systems,  thus  improving  economies and  reliability.  The
     application  of  phase  shifting  transformers,  series  compensation,  and
     flexible  alternating current  transmission system ("FACTS") technology has
     also  provided the ability to improve and control the transfer of power and
     energy across expansive  transmission  networks.  New flexible  alternating
     FACTS technology can increase the capacity of existing  transmission  lines
     by approximately 20 to 40 percent. Electricity: Innovation and Competition,
     Hearing  Before  the  Subcomm.  of Energy and Power of the House  Comm.  on
     Commerce, 105th Cong. 38 (1997) (statement of Robert B. Schainker, Manager,
     Substations,  Transmissions  and  Substation  Business Area Power  Delivery
     Group,  Electric  Power  Research  Institute).   Such  technology  "help[s]
     electric  utilities  operate  their  bulk  power  networks  closer to their
     inherent  thermal  limits,   while  maintaining  and/or  improving  network
     security and reliability." Id. Advances in telecommunications  and computer
     technology have improved the ability to economically dispatch power systems
     and   control   power   flow   across   such   systems.   Improvements   in
     telecommunication   technology   and  the  growth  in   coverage   area  of
     telecommunications systems have allowed for the quick and reliable transfer
     of data necessary to control and dispatch from a single location generation
     that  can be  scattered  over  large  geographic  areas.  The  improvements
     provided  by fast and  reliable  telecommunication  networks  allow for the
     control  and  economic  dispatch  of power  systems  that extend over large
     geographic areas, providing system operators an almost real time ability to
     monitor  and  control  the  power  system.   Significant   improvements  in
     transmission and resource planning have also occurred since 1935. There are
     several software packages available today that enable the system planner to
     model  the  operation  of most  of the  equipment  used on a power  system.
     Studies  can  be  performed   that  not  only   evaluate   power   transfer
     capabilities,  but also allow the system planner to add different  types of
     equipment  to  determine   their  impact  on  increasing   power   transfer
     capabilities.  Development  of such software has enabled the system planner
     to determine  what  equipment  functions  best as well as where and when it
     should be installed.  Further technological advances can be expected in the
     future as "power engineers" explore the potential for computers to optimize
     the efficiency and reliability of the North American power network.  Leslie
     Lamarre, The Digital Revolution, EPRI Journal, (Jan./Feb. 1998).

     Interconnections  have  proven so  beneficial  that  every  utility  in the
continental United States is interconnected with one of three Interconnects: the
Eastern  Interconnect,  which encompasses utilities in the eastern United States
and Canada from the Atlantic Ocean to the High Plains; the Western Interconnect,
which encompasses  utilities from the High  Plains/Rocky  Mountain region to the
Pacific Ocean; and ERCOT, which encompasses most of the State of Texas. FERC has
described the present state of the  transmission  sector of the electric utility
industry as follows:

     The  transmission  facilities  of any one utility in a region are part of a
     larger,  integrated  transmission  system.  From  an  electric  engineering
     perspective,  each of the three  interconnections in the United States (the
     Eastern, Western and ERCOT) operates as a single "machine."

     The  generation  sector  of the  electric  utility  industry  is also  very
different  than it was in 1935.  Concern over the  nation's  energy  future,  in
conjunction  with  other  factors,  led to  the  first  significant  legislative
development at the federal level affecting the electric  utility  industry since
the  enactment  of the Act and the FPA:  the  enactment  of the  Public  Utility
Regulatory Policies Act of 1978 ("PURPA").  PURPA requires utilities to purchase
the output of qualifying facilities ("QFs") at avoided cost rates established by
state  commissions./45  An effect of PURPA was to begin to  separate  generation
from the transmission and distribution  functions of utility  operations,  or to
put it another way, to broaden the scope of  integrated  electric  operations to
include  purchases  from third parties as well as a utility's own  production of
electricity.  Consistent with the intent of PURPA, in some states significant QF
resources were added in lieu of utility generation./46

----------
44   FERC has noted that "the  entire  Eastern  interconnection  is, as the name
     indicates, interconnected." North American Electric Reliability Council, 87
     FERC P. 61,161 (1999).

45   PURPA Section 210. 16 U.S.C. ss. 824a-3.

46   PSCo,  which has installed  capacity of more than 3,000 MW,  purchases over
     600 MW of capacity  and  associated  energy from QFs  pursuant to long-term
     agreements.

----------

     Following  the enactment of PURPA and the  development  of the QF industry,
independent  power  producers  ("IPPs")  emerged as another  type of  generation
supplier.  IPPs operate without a franchised service territory or an established
customer base and seek to sell the output of their generating  facilities in the
wholesale market, typically to a single utility. With many traditional utilities
wary of  investing  in new  generation  for a variety of  reasons,  IPPs in some
instances found a ready market.  IPPs were further spurred by the great latitude
that FERC afforded them in rate setting.  In fact, FERC initially  developed its
market-based rate standards in the context of IPPs./47 However,  the development
of IPPs was formerly inhibited by their lack of access to essential transmission
facilities to reach a broader  customer base, as well as ownership  restrictions
effectively  created by the  integration  requirements  of the Act.  Recognizing
these obstacles and desiring to promote  greater  development of wholesale power
markets  generally,  Congress passed the Energy Policy Act of 1992 ("EPACT")./48
EPACT amended the FPA to permit any entity selling power at wholesale to request
FERC to order a transmission-owning utility to provide transmission services./49
EPACT also created a new  exemption  under Section 32 of the 1935 Act for exempt
wholesale  generators  ("EWGs").  The EWG exemption  ensures that the 1935 Act's
integration  requirements will not thwart the development of IPPs  participating
in the wholesale market, an implicit  acknowledgment that the economic operation
of a utility system depends on contractual  relationships  as well as facilities
ownership.

     Since EPACT, the competitive electric supply wholesale market has developed
rapidly.  This progress has been facilitated by FERC's willingness to permit the
sale of  electric  capacity  and energy at  market-based  rates.  This change in
regulatory  policy  applies not only to IPPs,  but to power  marketers  (many of
which are  affiliated  with  utilities)  - a  relatively  new class of wholesale
market participant that purchases and sells power produced by third parties, not
from their own  resources.  This new policy also applies to utilities  directly,
who have increasingly  focused on their own wholesale  marketing efforts.  It is
now the rare utility that does not have either market-based rate authority or an
active wholesale power marketing affiliate./50

     Notwithstanding  these initiatives,  FERC concluded that due to the lack of
third-party transmission access, and preferential access that utilities accorded
to their own marketing efforts,  unequal transmission access continued to impede
the  development  of fully  competitive  bulk power  markets that FERC sought to
promote./51  On that basis,  within three years of the enactment of EPACT,  FERC
commenced the so-called "Mega-NOPR" proceeding,  Promoting Wholesale Competition
Through  Open  Access   Non-discriminatory   Transmission   Services  by  Public
Utilities;  Recovery  of Stranded  Costs by Public  Utilities  and  Transmitting
Utilities./52 This notice of proposed rulemaking culminated approximately a year
later with FERC's issuance of Order No. 888./53

     (1990).

49   PURPA also  included a  provision  that  allowed  the  Commission  to order
     wheeling   for   power   generated   by  a  third   party   under   certain
     narrowly-defined  circumstances.  However,  FERC quickly  interpreted  this
     already  limited  authority very  conservatively.  See  Southeastern  Power
     Administration  v.  Kentucky  Utilities  Co., 20 F.E.R.C.  P. 61,204 (1983)
     (holding that the Commission could not order wheeling if the wheeling order
     would result in a disturbance of existing market patterns, and holding that
     Section  211 of the FPA,  as added by PURPA,  was not  designed to remedy a
     utility's  anticompetitive  conduct). EPACT amended sections 211 and 212 of
     the FPA to  expand  the  Commission's  authority  to  order  wheeling  upon
     application. 16 U.S.C. Sections 824j, 824k.

50   The NSP companies, PSCo and SPS all have been granted market rate authority
     and participate  actively in wholesale  markets.  The NCE system also has a
     wholesale power marketer, e prime.

51   One commentator has described this unequal transmission access as follows:

          For more than 100 years,  electric  companies  operated  as  separate,
          regulated   monopolies   producing,   transmitting   and  distribution
          electricity  to their own customers or native load. The utilities were
          virtual  islands unto themselves with no competition and minimal risk.
          To help ensure a reliable  supply of electricity  when generators were
          down for  maintenance or during period of peak demand for  electricity
          and  other  shortages,  neighboring  utilities  installed  connections
          between their individual  transmission systems or control areas. Power
          could now flow  from one  neighboring  utility  to  another.  As these
          connections  expanded,  they  eventually  formed a  complex  "grid" of
          transmission   systems  or  control  areas  capable  of   transmitting
          electricity across must longer distances. Utilities also faced another
          challenge, wholesale competition.  Suddenly your neighboring utilities
          could buy electricity at potentially  lower prices from another,  more
          distant  supplier.  That meant lost business and lost income from your
          company. One way to reduce this threat was to set the price for access
          to your  company's  transmission  system so high  that it  discouraged
          other utilities from wheeling power across your territory.  The result
          was that  distant  power  suppliers  often found it  difficult  if not
          physically  impossible to wheel their  electricity to your  neighbors.
          You could also thwart  competition  by withholding  information  about
          transmission  pricing and availability,  or the hours when your system
          had sufficient capacity to handle the additional flow of electricity.

----------

     Order No. 888  requires  all  transmission  owners to (1) offer  comparable
open-access  transmission  service for wholesale  transactions under a tariff of
general  applicability on file at FERC/54 and (2) take transmission  service for
their own  wholesale  sales under their  open-access  tariff.  Order No. 888 was
intended to facilitate  third-party  utilization of the transmission grid as the
vehicle for developing a competitive  wholesale  bulk power market.  Under Order
No. 888, a utility  must wheel power for third  parties upon their  request,  on
either a firm or a non-firm basis./55 If the transmitting  utility does not have
sufficient  transmission  capacity to  transmit on a firm basis,  it must either
offer to expand its  transmission  system to  accommodate  the  request,  or, if
appropriate,  to redispatch  generation to relieve  constraints and thereby make
transmission   capacity  available.   In  the  interim,  a  utility  must  offer
transmission on a non-firm basis to the requesting entity./56

----------
54   FERC has explained what it means by comparability:

          an  open  access   tariff  that  is  not  unduly   discriminatory   or
          anticompetitive  should  offer  third  parties  access  on the same or
          comparable   basis,  and  under  the  same  or  comparable  terms  and
          conditions, as the transmission provider's uses of its system.

55   "Wheeling"  is the provision of  transportation  by a hub operator from one
     system to another system.

56   Moreover,  FERC in Order  No.  888  required  tight  power  pools (or their
     individual  members) both to file open-access  transmission  tariffs and to
     file revised  pooling  agreements by December 31, 1996. With respect to the
     latter  requirement,  FERC  required  that the  reformulated  power pooling
     agreements   establish,   among  other  things,  open,   non-discriminatory
     membership  provisions,  that would allow any bulk power market participant
     to join a power pool,  irrespective  of its type,  affiliations  with other
     entities,  or geographic  location.  In Order No. 888, FERC expressly noted
     that the  reformation  of tight power  pools could be achieved  through the
     establishment  of an ISO to supplant  the tight power pool.  As a result of
     this encouragement and FERC's  requirements,  the three primary tight power
     pools - Pennsylvania-New  Jersey-Maryland Interconnection ("PJM"), New York
     Power  Pool  ("NYPP"),  and  New  England  Power  Pool  ("NEPOOL")  -  have
     restructured into ISOs, and have significantly modified their operations.

----------

     Prior to Order No. 888,  electric  utilities  typically needed to construct
direct  interconnections to facilitate capacity and energy transfers.  Now, as a
matter of right under Order No. 888, two utilities can contractually arrange for
interconnection:  by  contract,  they can  acquire  either a firm or a  non-firm
transmission  path that would  allow  power  transfers  between  their  separate
systems.

     Moreover,  Order No. 888's  companion  order,  Order No.  889,/57  requires
public  utilities to functionally  separate their  transmission  and reliability
functions from their wholesale power marketing  functions.  In this  connection,
Order No. 889 required  public  utilities to develop and maintain an Open Access
Same-Time  Information  System  ("OASIS")  to give  transmission  users the same
access to transmission  information  that the wholesale  merchant  function of a
utility  enjoys.  The  fundamental  purpose  of  an  OASIS  is  to  ensure  that
transmission  customers  have  access  to  transmission   information,   through
electronic  means,  that will  enable  them to obtain  open-access  transmission
service  on a  basis  comparable  to a  transmitting  utility's  own  use of its
system./58  Generally stated, a utility's wholesale merchant function is limited
to receiving from a utility's  transmission  and reliability  function only such
transmission  information  that is posted on an OASIS,  and is thereby  publicly
available on a simultaneous basis to third-party  transmission customers.  Thus,
while  FERC  in  Order  Nos.  888  and 889  did  not  require  actual  corporate
divestiture or legal separation of generation and transmission  functions within
utilities, on an operational basis there has been a de facto separation of these
functions in response to these orders.

58   The   information  to  be  posted  on  an  OASIS  includes  the  following:
     transmission capability that is available on both a firm and nonfirm (i.e.,
     interruptible)   basis;    descriptive   information   regarding   specific
     transmission  requests and transactions  including the point of receipt and
     delivery on the transmitting  utility's  system,  the term of service,  the
     level (i.e., number of MWs) and quality (i.e., firm or nonfirm) of service,
     and  whether the  service is  provided  for the  benefit of a  transmitting
     utility's  associated  wholesale  merchant  function  or to  an  affiliate;
     whether any  transmission  services have been offered at a discounted rate;
     and notices regarding  transmission  curtailments or interruptions.  See 18
     C.F.R. ss.37.6.

----------

     The comparable transmission service and functional unbundling that FERC has
required  in Order  Nos.  888 and 889  initially  may appear to  contradict  the
integrated  operation  of electric  systems  required  under  Section 11.  Taken
together,  the two orders require utilities to deprive themselves of any benefit
associated with the  consolidation  of ownership of transmission  and generation
facilities.  Instead, under the concepts supporting Order Nos. 888 and 889, such
benefits  are created by the  competitive  marketplace  that  results  from open
access.  As FERC  stated  in  Order  No.  888,  "[i]ncreasingly,  customers  are
demanding the benefits of competition in the growing electric commodity market."
FERC estimated quantitative benefits of its rule of $3.8-$5.4 billion a year, in
addition to expected  non-quantifiable  benefits  such as better use of existing
assets and institutions,  new market mechanisms,  technical  innovation and less
rate distortion.  According to FERC, the continuing  competitive  changes in the
industry and the prospect of these benefits to customers made it imperative that
FERC ensure  nondiscriminatory  transmission  access  through Order Nos. 888 and
889./59 Thus, FERC has recognized that the economic operation of utility systems
can be  achieved,  and  indeed is perhaps  best  achieved,  through  contractual
relationships in a competitive marketplace,  and not simply through ownership of
facilities.

     EPACT, Order Nos. 888 and 889, and other FERC policies and initiatives have
had a tremendous  impact on the  development of competitive  bulk power markets.
Utilities have increased their own in-house wholesale  marketing efforts and the
number of  entities  with whom they trade.  To  illustrate  by  example,  PSCo's
non-requirements  wholesales sales (including short-term firm and economy sales)
have  increased  from  306,920 MWh in 1993 to 7,873,800  MWh in 1998.  Moreover,
whereas PSCo's past wholesale  marketing efforts were largely limited to economy
energy  sales made by its  dispatchers  in the former  Inland  Power  Pool,  New
Century  Services  now has a marketing  group that makes sales on behalf of PSCo
throughout the entire western region.  Similarly,  NSP's revenues from sales for
resale have increased by 70% from 1996 to 1999. While trades were typically made
within  MAPP and MAIN in the  past,  NSP has  found  it  economical  to trade in
markets such as Ohio and Florida.

     Moreover,  power  marketers are an increasingly  important  presence in the
industry.  The top ten power  marketers sold in excess of 1 billion MWh in 1999.
These entities typically  arbitrage  remaining price  differentials by buying in
one  market and  selling in  another.  The effect is to  minimize  margins to be
gained in these  interregional  sales and  therefore  to drive  electric  supply
market  prices  closer to a  regional-wide  marginal (or  incremental)  cost. As
prices  move to  marginal  cost,  rate  differentials  arising  from  historical
embedded  cost  will  begin  to  disappear./60  IPPs  also are  becoming  a more
significant sector of the electric utility industry.  Nationwide, plans to build
new plants have exploded.  In the Northeast  Power  Coordinating  Council region
alone,  an  additional  30,000  MWs has been  announced,  almost  all of it from
IPPs./61  Similar plant  additions  have been  announced by IPPs and EWGs in the
mid-continent  area as well. These significant plant additions lessen the impact
of historical embedded utility-specific price differentials by changing the cost
structure of the industry as a whole.

59   Order No. 888.

60   One  commentator  has  recently  described  the  ramifications  of the more
     competitive wholesale markets resulting from the enactment of EPACT and the
     issuance of Order Nos. 888 and 889 as follows:

          What resulted is a highly competitive and sophisticated  24-hour power
          market . . .

               Next we examine  what  happens in  "real-time"  . . . .  Economic
               power  schedulers,  working  in the  front  office,  monitor  the
               utility's entire real-time system,  making sure that the planners
               have  accurately  matched the power supply assets with the hourly
               demand or native load.  Economic power  schedulers also make sure
               that the planners have utilized the least  expensive power supply
               assets. Schedulers may also make adjustments to the power plan in
               order  to  maximize  the  goals  of  reducing  costs,   providing
               customers  with the lowest  possible  wholesale  prices.  To make
               these  adjustments,  economic power  schedulers rely on available
               power supply assets and the hourly or "spot"  market.  Unexpected
               changes in the  weather,  mechanical  problems at the  generating
               station and congestion on the transmission grid are only a few of
               the  factors  that can result in  deviations  from the  planner's
               schedule. Let's assume the scheduler needs an additional 10 MW of
               power for two hours,  one hour from now. He or she,  depending on
               the level of  sophistication  of the company,  may consult a data
               screen that  displays  the  real-time  spot-market  price and the
               incremental  cost of  generation  or the  cost of  producing  the
               additional or next 10 MW of electricity.

               If the  incremental  cost of  generation  is less than the market
               price,  the  power  scheduler  may ask the  generating  plant  to
               increase  production  or start a  peaking  unit.  If the price of
               power from  pre-existing  contracts  is less than the spot market
               price or  generation,  the  scheduler may draw upon the amount of
               electricity  stipulated in the  contract.  But if the spot market
               price is less than the incremental cost of generation or contract
               power,  the  scheduler  may  notify  the  traders  in the  "front
               office."  They  immediately  go to the spot  market and begin the
               buying process.

               The economic  power  scheduler  may also find that the utility is
               "long" on power or has excess  capacity  for several  hours.  The
               traders  may now begin the selling  process.  Trading in the spot
               market has the same requirements as day-ahead, weekly and monthly
               trading except that it happens at a much faster pace. Spot market
               trading  averages  less than 20 minutes  for  securing a buyer or
               seller scheduling transmission or obtaining an NERC tag, applying
               competitive  intelligence  and price and credit risk  management,
               confirming   the  trade  and  notifying   billing,   finance  and
               accounting in the "back office."

61   Order No. 2000 at p. 30,996.

----------

     FERC's  commitment to expand wholesale  markets was reinforced in its Order
No. 2000,  FERC's final rule on regional  transmission  organizations  ("RTOs").
RTOs are  intended to create  regional  planning and  operation of  transmission
systems  to allow  greater  efficiency  in the  market  as well as to  eliminate
pancaked rates,  making the transmission  grid more like the interstate  freeway
system and thereby enabling power to flow cheaply over longer  distances.  Order
No. 2000 sets out FERC's expectation that all transmission owners will join RTOs
on a  voluntary  basis.  To that  end,  FERC  announced  a  timetable  for every
jurisdictional  utility to either join in an RTO filing, or,  alternatively,  to
submit a filing  describing  its efforts to join in an RTO,  the reasons for not
participating  in an RTO proposal and any  obstacles to  participation,  and its
plans for further  work toward  participation.  This  timetable  is  aggressive,
requiring that utilities not already  participating in a FERC-approved  RTO make
such initial filing by October 15, 2000.

     Order 2000 states that an RTO must  provide the  following  functions  at a
minimum: (i) tariff administration and design; (ii) congestion management; (iii)
parallel  path flow  management;  (iv)  supplier  of last  resort for  ancillary
services;   (v)  OASIS  site  administration  and  the  determination  of  total
transmission   capability  and  available  transmission  capacity;  (vi)  market
monitoring;  (vii)  system  planning  and  expansion;  and (viii)  interregional
coordination./62  These  minimum  characteristics  and functions are intended to
have  the  effect  of  turning  the  nation's   transmission   facilities   into
independently owned and operated "common carriers" that offer comparable service
to all would-be users.

     FERC  expects  that  RTOs  will  promote  economic  efficiency  as  well as
operational efficiency. A significant barrier to equalizing the trading price of
a more distant utility with a nearby utility is the cost of transmission,  which
is hampered by the "pancaking" of rates under the current  transmission  pricing
scheme.  Simply stated,  if a transaction  requires movement of power across the
transmission system of multiple, non-affiliated public utilities:

          [the]  transmission  customer pays separate,  additive  access charges
          every time its contract  path  crosses the boundary of a  transmission
          owner. By raising the cost of transmission, pancaking reduces the size
          of geographic power markets. This, in turn, can result in concentrated
          electricity  markets.   Balkanization  of  electricity  markets  hurts
          electricity  consumers,  in  general,  by  forcing  them to pay higher
          prices  than they  would in a larger,  more  competitive,  bulk  power
          market./63

As such,  wholesale  generators or customers seeking to buy competitively priced
generation in more distant markets must pay  transmission  costs that may exceed
the benefits of the transaction.

     Among other  benefits,  an RTO price  structure  eliminates rate pancaking,
allowing  power on the most distant edges of an ISO to be  transmitted at market
price with no  additional  cost for  transmission  than would exist for a nearby
transaction  or even the  generation-to-end-user  within a utility's own service
area. FERC has explained this benefit:

          The Commission has long recognized that transmission pricing reform is
          most  effectively  accomplished on a regional basis. An RTO would have
          the geographic scope needed to eliminate  pancaked  transmission rates
          within its region.  This would broaden the generation market and could
          result in more potential  suppliers and less  concentrated  generation
          markets,  thereby fostering more competitive  markets and lower prices
          to consumers./64

Because  RTOs will offer  service to customers  on a  system-wide  basis under a
single FERC-approved tariff,  customers will have available "'one stop shopping'
for regional  transmission service . . . resulting in simpler and more efficient
procedures for transmission users to transmit power over greater distances."/65

----------
62   FERC added the  interregional  coordination  function  in Order No. 2000 in
     order to assure that "seams" issues between RTOs (or between RTOs and areas
     where there is not yet an RTO) are adequately addressed.  As FERC stated in
     Order  No.  2000,   "[c]oordination   of  activities  among  regions  is  a
     significant  element in maintaining a reliable bulk transmission system and
     for the development of competitive markets." Order No. 2000 at p. 31,167.

----------

     Due to these and other  developments at the federal level, the landscape of
the  electric  industry  is  changing  rapidly.  Wholesale  power  markets  have
developed from a balkanized,  utility-specific,  cost-based  structure to a more
competitive  market-based  structure./66 The effect of these developments on SEC
merger  policy is both  direct  and  profound.  The  emergence  of RTOs,  at the
direction of FERC, will further  facilitate  wholesale  competition,  moving the
industry  further  from the  vertically-integrated  utility  model  under  which
utilities  relied  substantially  on their own  resources  to serve their loads.
Because  NSP and NCE can,  pursuant  to Order No. 888 and now Order 2000  obtain
transmission  rights that allow them to procure energy from more distant markets
at prices equivalent to or better than nearby markets in which they do business,
direct  physical  interconnection  is no longer  necessary  for the utilities to
transact  with,  or act in unison  with,  one  another  to  achieve  operational
efficiency. For example, in situations where two non-contiguous utilities in the
same  RTO  wish  to  transact  with  each  other,  they  can  arrange  necessary
transmission  services using a contract path or the RTO's  non-pancaked  tariff.
Moreover,  using either a contract path or a regional tariff, two non-contiguous
utilities  in the same RTO may reach  common  suppliers or hubs to both sell and
purchase electricity collectively. The net effect of these regulatory and market
changes is to require a re-evaluation  of the meaning of integration in light of
the  present   structure  of  the  electric   utility  industry  and  regulatory
environment,  which have changed  dramatically  since the passage of the Act./67
The Commission  already has recognized many of these changes in its decisions in
UNITIL  Corp.,  Holding Co. Act Release No. 25524 (April 24, 1992) and Conectiv,
Inc., Holding Co. Act Release No. 26832 (February 25, 1998).

----------
66   Indeed,  FERC  in  Order  No.  888  invoked  the  widely-differing  cost of
     utility-generated  electricity  across the major  regions of the country as
     evidence of the need for reform. Order No. 888 at 31,651-52.

67   See also Order No. 2000 at p. 31,174 ("A main reason that an RTO can expand
     the  marketplace  for  generation  to a  large  region  is  that an RTO can
     implement non-pancaked rates for each transaction. A wider area served by a
     single rate means more generation is economically available to any customer
     which means greater competition for energy.")

----------

     Regulatory  changes at the state level have paralleled those at the federal
level and have been  equally  dramatic.  Concurrent  with or  subsequent  to the
implementation of PURPA,  states began developing  integrated  resource planning
requirements   that  mandate  that  utilities  focus  on  both  supply-side  and
demand-side  resources and that require local utilities  competitively bid their
resource requirements to obtain the lowest cost resources possible.  Under these
resource  procurement  requirements,  utilities  must purchase  power from third
parties  (rather than provide for their own generation) if to do so would result
in lower costs to consumers.  Typically,  special evaluation procedures apply to
assure the fairness of the bidding  process where a utility  desires to pursue a
self-build  option  or where an  affiliate  desires  to submit a  proposal.  The
bidding  process has also become the manner in which QF suppliers are chosen for
avoided cost sales. For example,  the Colorado Commission has adopted integrated
resource  planning  rules that  require  that  utilities  in Colorado  conduct a
competitive  resource procurement process for all additions of capacity to their
systems, except in very narrow circumstances,  e.g., capacity and/or energy from
the  generation  facilities of other  utilities or from  non-utility  generators
pursuant  to  agreements  for  less  than one  year  term or for  less  than ten
megawatts of capacity.  In the event that a Colorado  utility wishes to pursue a
self-build  option of  greater  than 10 MW,  it must  submit a  proposal  in the
competitive process. SPS and NSP are likewise subject to competitive procurement
procedures./68  Thus, the state  regulators  have  recognized  that the economic
operation of a utility system must include the benefits of  integration  through
the  marketplace and not just the effects of a  vertically-integrated  ownership
structure.

     Moreover,  virtually every state,  either at the  legislative  level or the
state regulatory  commission  level, has implemented or is actively  considering
retail competition.  One consequence of such actions has been the divestiture by
utilities of large amounts of generating  assets to relieve stranded costs or in
response to a state  mandate.  Since  August  1997,  approximately  50,000 MW of
generating  capacity  have  been  sold  (or are  under  contract  to be sold) by
utilities,  and an additional  30,000 MW is currently  for sale. In total,  this
represents more than 10 percent of U.S. generating  capacity./69 The combination
of state  restructuring  efforts and federal  unbundling  of  transmission  from
generation  makes it clear  that  utilities  will not be  encouraged  to achieve
saving from mergers through the combination of generating facilities. The lowest
cost supply of power will be achieved in the market, and consumers will directly
access that market.

----------
68   As stated  previously under Item 1.C.2.,  NSP recently  submitted a request
     for bids for up to 1,200 MW of capacity.

69   Order No. 2000 at 30,997.

----------

     The two states in which SPS  principally  operates,  Texas and New  Mexico,
vividly illustrate the trend towards retail electric competition. Both Texas and
New Mexico in 1999 enacted restructuring legislation requiring that historically
integrated   utilities,   including  SPS,   unbundle  their   transmission   and
distribution  operations  from their energy  supply  operations  (including  the
generation function) through corporate reorganizations or divestitures of assets
to facilitate retail competition in those states.

     To elaborate,  New Mexico SB-428,  which was enacted in 1999,  will require
the corporate  separation of SPS's generation and competitive  energy operations
from its regulated transmission and distribution operations in New Mexico. Texas
SB-7,  which also was enacted in 1999, will require the corporate  separation of
SPS's generation, retail marketing, and transmission and distribution operations
in Texas.  Moreover,  SB-7 requires Texas utilities to sell at auction, at least
sixty days before customer choice is to begin in Texas, entitlements to at least
fifteen percent of their jurisdictional  installed capacity,  and further limits
the amount of installed  generating capacity that a generating company in Texas,
including those formed through the corporate  separation of existing  integrated
utilities,  may own. Texas SB-7  establishes a 20 percent limit on the amount of
capacity that any entity can own or control in a power region.

     Both  New  Mexico  SB-428  and  Texas  SB-7  require  utilities  to  submit
compliance or "transition" plans for state commission  approval.  In New Mexico,
SPS must file its transition plan by June 1, 2000, seeking New Mexico Commission
approval by December 1, 2000.  In Texas,  SPS on January 10, 2000 filed its plan
to  separate  its  retail,   generation,   and   transmission  and  distribution
businesses. By December 1, 2000, SPS must file its market power mitigation plan.
Moreover,  in its order  setting the Merger for  hearing,  the Texas  Commission
requested that SPS file supplemental direct testimony  addressing the structural
and operational changes that SPS would make to comply with SB-7.

     In  addition  to  addressing  various  merger-related  issues,  SPS reached
agreement  in its  merger  proceeding  in Texas  with  respect to several of the
restructuring  requirements  of Texas SB-7. In order to address  vertical market
power issues,  SPS agreed to join the SPP transmission  tariff immediately after
Texas approval of the merger, as an interim measure until FERC's formal approval
for SPS to join the MISO.  In addition,  in order to address  horizontal  market
power issues, SPS agreed to provide economic dispatch and reliability pooling on
a comparable and non-discriminatory basis at FERC-regulated  cost-based rates to
loads in SPS's service area. Such service will be offered beginning June 1, 2001
and  will  continue  until  the  later  of  the  date  on  which  FERC  approves
market-based  rates for ancillary  services  supplied in the SPS service area or
when the PUCT certifies that SPS operates in a competitive power region. Also to
address  horizontal  market  power,  SPS and its  affiliates  agreed  to  divest
approximately  2,864  megawatts of generation  capacity in the SPS service area.
This amounts to about 64 percent of the 4,472 megawatts of capacity owned by SPS
and its  affiliates  at 13 plants in Texas and New Mexico.  The  agreement  also
provides that SPS may sell 3,191 megawatts or 71 percent of its capacity, if the
Texas  Commission  deems the larger amount  necessary for SPS to be certified as
operating in a qualified  power  region.  The  agreements  to sell  capacity are
subject to the pooling of interests requirements and sufficient participation of
bidders in the divestiture  sale to permit  reasonable  competition and multiple
purchasers.

     To  summarize,  the ongoing  corporate  restructuring  of the U.S.  utility
industry reflects the effects of emerging FERC policy on transmission (including
Order Nos. 888 and 889 requiring  open-access  transmission on comparable  terms
and  the  functional  unbundling  of the  transmission  and  wholesale  merchant
functions),  the formation of ISOs and Order No. 2000. It is also the product of
many recent state laws mandating  competitive  resource  procurement  and retail
electric  competition,  and the  functional  separation  (and  in  some  states,
divestiture)  of  generation  from  transmission  and  distribution  operations.
Layered on these  changes  are both rapid  developments  in  technology  and the
emergence and growth of the power marketing and energy trading businesses,  both
of which facilitate efficient and competitive low-cost electric markets. Perhaps
most notable  among all of these  changes is the recent  evolution of ISOs/RTOs.
These  entities  facilitate  trading  regions  with no economic  constraints  on
transmission access and with the ability to manage and plan for new transmission
on  a  regional  basis  to  help  alleviate  transmission  constraints,  thereby
providing  entities  with both the  requisite  physical  and  economic  means to
integrate   their   systems.   The  cumulative   effect  of  these   regulatory,
technological  and economic changes has  dramatically  altered the "state of the
art" that  Congress  directed the  Commission  to consider more than sixty years
ago.

                                    * * * * *

     It is  against  this  backdrop  of rapid  change  in the  electric  utility
industry and the regulatory  framework that  Applicants have developed a plan to
integrate the NCE and NSP systems. There are two primary components to this plan
in addition to the common  utilization by the NCE and NSP systems of New Century
Services  for  numerous  procurement,  operational,  administrative  and general
services.  First,  Applicants  have  completed the process of arranging a 100 MW
south to north firm transmission path from 2002 through 2004 between SPS and the
NSP.  This  contract  path  will  integrate  the  Xcel  operating  companies  by
permitting cost savings from power  transfers  between NSP and SPS initially and
later between NSP and PSCo. Second, the Xcel operating companies will be parties
to the Joint Operating  Agreement,  which FERC has already  approved in the FERC
Merger  Order.  The  Joint  Operating  Agreement  provides  the  basis  for  the
coordination of the Xcel operating companies generating resources,  and sets out
the  contractual  framework for them to transact with each other and to transact
with third parties on a joint basis.  This  integration plan will be facilitated
by NSP, NSP-W and SPS joining the same ISO,  namely MISO. The contract path, the
Joint Operating  Agreement and MISO are explained  below,  followed by a showing
how the Xcel  Electric  System will be an  integrated  electric  utility  system
within the meaning of Section 2(a)(29)(A).

     The Contract Path

     For at least three years following  consummation of the Merger, NCE and NSP
will  interconnect  their  systems  through  three  firm  transmission   service
agreements,  which  provide  a firm 100 MW  unidirectional  path from SPS to NSP
(through  the SPS,  SPP and Ameren  transmission  systems),  to flow 100 MW from
points of receipt located at SPS's generating stations to a point of delivery at
the interconnection between Ameren and NSP transmission systems (the "Northbound
Path").  Applicants  commit  either to extend their right to use the  Northbound
Path prior to its expiration or to file a  post-effective  amendment  explaining
how the Xcel operating  companies  will continue to satisfy the  interconnection
requirement  if  their  rights  with  respect  to the  Northbound  Path  are not
extended.

     The  Northbound  Path will enable the operating  companies to move 100MW of
power from SPS  generation to the NSP's service  territory 365 days a year.  The
Northbound Path is a firm transmission arrangement that Applicants have arranged
under the open-access  transmission  tariffs of the Southwest Power Pool ("SPP")
and Ameren.

     Specifically,  power  under this path will  leave the SPS  system  from its
generation facilities and flow to the border between the SPS transmission system
and the  transmission  system of Public Service Company of Oklahoma  ("PSO") (an
operating company of Central and South West Corporation ("CSW")).  These PSO/CSW
facilities are subject to the regional transmission tariff of the SPP. To comply
with  the  requirements  of the SPS  open-access  transmission  tariff,  the SPS
wholesale  merchant  function has arranged for service from the SPS transmission
function under the SPS open-access transmission tariff for the delivery of power
to the interface of the SPS and PSO/CSW  transmission  system, which consists of
the Elk City and Oklaunion  substations.  (See the orange lines on Exhibit 3.4).
SPS owns  the 345 kV line to  Oklaunion  and  owns the 230 kV line to the  Texas
border  with an  interest  in the right to use the  capacity of such 230 kV line
from the Texas/Oklahoma border to Elk City./70

----------
70   SPS,  like many  transmission  owners  such as Public  Service  Company  of
     Oklahoma,  owns the both the  assets  and the  rights  to use  transmission
     capacity beyond it service area boundary.  Thus the SPS transmission system
     is  appropriately  viewed as extending  to both the Elk City and  Oklaunion
     substations.

----------

     On February 22, 2000,  SPS entered a  transmission  agreement with the SPP,
acting as tariff administrator for PSO/CSW, to provide transmission service over
facilities  of PSO/CSW to the Ameren  border.  The  contract is for a three year
period.  Although the SPP does not require a specific  facility  route,  primary
paths  are on a 138 kV line  from  Elk  City  to the  Cimarron  substation  near
Oklahoma  City and on a 345 kV line from  Oklaunion  to the Mustang  substation,
also near Oklahoma City. The Northbound Path continues on a 345 kV system to the
Ameren border near the Bolivar Burns substation around Springfield, Missouri, at
the southwest corner of the Ameren system (see the green lines on Exhibit 3.4).

     On January 25, 2000,  NSP  reserved  100 MW of firm  capacity to move power
from any point on the Ameren  system (in this case,  the SPP border with Ameren)
to the Montgomrey  substation in eastern  Missouri (see the blue line on Exhibit
3.5).  This path is needed to move power  across  the  Ameren  system to the NSP
transmission  system,  which extends from the  Minneapolis/St.  Paul area to the
Montgomrey substation.  This contract is also for a period of three years and is
coterminous  with the SPP  contract.  NSP will  utilize  its  rights  under  the
Minneapolis/St.  Paul,  Iowa,  St. Louis 345 kV  Interconnection  Agreement (the
"East Line Agreement") to move power from the Montgomrey, Missouri substation to
the NSP service area. The East Line is jointly owned by NSP, Ameren, Alliant and
Mid American.  Each party owns a physical  portion of the line and has the right
to use the entire line.  Specifically,  under the East Line Agreement,  NSP owns
100% of the portion of the line from the Twin Cities to the Adams  substation at
the Minnesota/Iowa  border and has a 27% interest in the right to use the line's
transmission  capacity from  designated  points all along the line from the Twin
Cities to St. Louis. In this case, the point at which NSP has elected to receive
power  pursuant  to its right to use the entire  East Line is at the  Montgomrey
substation,  from which  point it will  deliver  the power to any point in NSP's
service area, typically to Minneapolis/St.  Paul, Minnesota area/71 (see the red
line on Exhibit 3.5).

     The  combinations of these  agreements  provide a single contract path (via
two  distinct  contracts)  by  which  SPS can  move  100 MW of  power  from  its
transmission  system  to  NSP's  transmission  system.  The  Northbound  Path is
approximately  500  miles  (from  the  Elk  City  substation  to the  Montgomrey
substation)./72  The Xcel  operating  companies  have all rights  needed to move
power from the border of the SPS system (either at Elk City or Oklaunion) to the
border of the NSP system at the Montgomrey substation in Missouri.

----------
71   Like the SPS and PSO/CSW  transmission  systems,  NSP's transmission system
     extends beyond its service area border.

72   The distance from the Oklaunion substation to the Montgomrey  substation is
     approximately 550 miles.

----------

     The Northbound Path will provide NSP, which is a net purchaser of energy in
both summer and winters seasons, the opportunity to import power from SPS to NSP
during those  seasons (as well as  throughout  the year during  periods when the
incremental  cost of SPS  generation is lower than NSP's)  pursuant to the Joint
Operating  Agreement.  The Northbound Path  interconnects and integrates the NCE
and NSP systems in the same manner as the contract path found  acceptable by the
Commission in the AEP/CSW  Order.  At 100 MW, the Northbound  Path  represents a
slightly greater proportion of Xcel's total utility generating capacity than the
amount reserved between AEP and CSW.

     Certain PSO upgrades will be required with respect to the Northbound  Path.
The upgrades will be made by PSO pursuant to the transmission service agreements
that have been executed by SPS under the SPP Open Access Transmission Tariff.

     The Applicants initially proposed that the Northbound Path be a 200 MW firm
path,  as  compared  to 100 MW firm path,  as 200 MW could be  physically  moved
between the two systems on a firm basis and would result in additional  savings.
However,  preliminary  analysis  of this  scenario  indicated  that  the loss in
available  capacity in the NSP destination  market was likely significant enough
to cause a potential  screen failure under FERC's  guidelines  related to market
power,  which could have  resulted in NSP being  required to divest a portion of
its generation assets.  Because NSP is currently acquiring additional generation
resources,  divestiture  would be inconsistent  with its growing need for energy
and capacity to serve its  customers.  Thus,  the  Applicants  chose to have the
Northbound  Path be a 100 MW firm path from SPS to NSP, which does not result in
the  same  concern./73 The 100 MW  Northbound  Path  will  serve to  reduce  the
operating costs by allowing for firm power  transfers from SPS to NSP,  creating
projected savings of $24 million over the next ten years.

     The Joint Operating Agreement

     The Joint  Operating  Agreement will integrate the generating  resources of
NSP, NSP-W, PSCo and SPS (individually, an "Operating Company" and collectively,
the "Operating  Companies").  More specifically,  the Joint Operating  Agreement
sets out the framework for the coordinated planning, operations, and maintenance
of generation  resources (both owned and purchased),  and coordinated  wholesale
marketing  activities  of the Operating  Companies./74  It also provides for the
allocation of associated costs and benefits.

----------
73   Also, the  Northbound  Path (like  virtually  every firm contract path) has
     some market concentrating effects as a result of the loop-flows, as well as
     market  de-concentrating  effects.  For this reason,  Applicants  initially
     supported  the  Northbound  Path as a  separate  option  from MISO in their
     filing  for FERC  approval  of the  Merger.  If FERC had not  approved  the
     Northbound Path without a hearing, the Applicants would have requested FERC
     and the SEC to approve the Merger without the Northbound Path. The issue is
     now moot as the FERC unconditionally approved the Merger without a hearing.

74   Cheyenne  is not a part to the  Joint  Operating  Agreement  as it does not
     operate any generation assets or make any wholesale sales.  Thus,  Cheyenne
     has no owned generation resources subject to integration as a result of the
     Merger.

----------

     An Operating  Committee will have overall  responsibility for administering
the Joint Operating  Agreement.  The Operating  Committee will be comprised of a
representative  of each of the  Operating  Companies  and New Century  Services,
which will act as the agent for the Operating Companies.

     In accordance with the terms of the Joint Operating Agreement,  New Century
Services will undertake a number of activities involving the coordination of the
generating resources of the Operating Companies, including the following:

          (a)  evaluating  and making  recommendations  concerning  additions of
               generating  facilities  or  capacity  to be  owned  by,  or under
               long-term   contract,   to  an  Operating  Company   ("Generation
               Resources")  in  order  to  meet  the  load  requirements  of the
               Operating Companies;

          (b)  coordinating  the planning and design of Generating  Resources to
               be installed or acquired by the Operating Companies;

          (c)  coordinating the operation and maintenance of Operating Companies
               Generating Resources;

          (d)  coordinating  the economic  dispatch of Generating  Resources for
               the Operating Companies;

          (e)  conducting system purchases and sales and off-system marketing on
               behalf of the Operating Companies;

          (f)  developing all bills and billing  information among the Operating
               Companies under the Joint Operating Agreement;

          (g)  acquiring  and  coordinating  the provision of  transmission  and
               ancillary services from affiliated and non-affiliate transmission
               providers  for use  with  respect  to  transactions  by or  among
               Operating Companies;

          (h)  operating  and maintain a central  generating  control  center to
               achieve these purposes,  and such additional  generation  control
               centers as the Operating Companies may require; and

          (i)  reassigning transmission services obtained for wholesale merchant
               purposes on behalf of any Operating Company.

     Section 7.2 of the Joint Operating  Agreement  provides for the coordinated
operation of each of the Operating  Companies'  resources.  While preserving the
pre-Merger dispatch  priorities  applicable to each company's resources to allay
any possible state regulatory concern regarding  cost-shifts among the Operating
Companies,  this  section  further  provides  that "the  Control  Areas  will be
dispatched  on a  coordinated  basis in real time to minimize  total  generation
costs  for  the  Operating  Companies,  subject  to  the  availability  of  Firm
Transmission   Entitlements  or  other  transmission  arrangements  linking  the
Operating Companies' Control Areas or other transmission services."

     The Joint Operating Agreement also contains service schedules providing for
actual power  transactions  among the  Operating  Companies or by the  Operating
Companies  acting  jointly  with  non-affiliated  third  parties.  Specifically,
Service Schedule A provides for the sale of capacity and associated energy sales
by one Operating Company to another. Service Schedule B provides for energy-only
sales by one  Operating  Company to  another.  Service  Schedule C provides  for
system sales and purchases,  and off-system  marketing  (i.e., not involving the
generating  resources of the  Operating  Companies)  with  non-affiliated  third
parties.  Service  Schedule D provides for the  allocation of costs and revenues
associated  with any firm  transmission  paths that the Operating  Companies may
obtain to link their systems.

     Applicants  note  that NSP and NSP-W  currently  coordinate  the  planning,
construction,  operations and maintenance of their electric supply facilities on
an integrated basis and operate as a single coordinate  electric system pursuant
to an  Interconnection  and  Interchange  Agreement dated September 17, 1984, as
subsequently  modified and supplemented  (the "NSP Interchange  Agreement).  For
this reason,  NSP and NSP-W are treated as a single Operating  Company under the
Joint  Operating  Agreement  for virtually  all  purposes.  The Joint  Operating
Agreement  is  intended  to be in  addition  to,  and  not in lieu  of,  the NSP
Interchange  Agreement.  Yet,  in  the  event  of an  inconsistency,  the  Joint
Operating Agreement will control.

     Applicants  submitted the Joint  Operating  Agreement to FERC  concurrently
with their  application  to merge.  FERC in the FERC Merger  Order  accepted the
Joint Operating Agreement for filing without  modification,  only conditional on
the  consummation  of the Merger.  FERC has  jurisdiction  over the actual power
transactions  set out in the Joint  Operating  Agreement.  The costs for various
non-power  transaction  activities  (e.g.,  for joint  planning)  will likely be
incurred at the service  company  level and  allocated  in  accordance  with the
SEC-jurisdictional service agreements.

     MISO

     MISO is a voluntary  non-profit  corporation  and, as FERC has  recognized,
MISO is unique in that it "began through a consensual process and was not driven
by  a  pre-existing   institution."/75   MISO's  participants   include  various
transmission-owning  electric utilities  ("Transmission  Owners") located in the
Midwest. The initial Transmission Owners currently are Ameren Corporation (which
includes  Central  Illinois Public Service Company and Union Electric  Company),
Central Illinois Light Company,  Cinergy Corporation (which includes PSI Energy,
Inc.,  Cincinnati  Gas &  Electric  Company  and  Union  Light,  Heat and  Power
Company),   Commonwealth   Edison   Company,   Hoosier   Energy  Rural  Electric
Cooperative,  Illinova Corp., LG&E Energy Corp.  (which includes  Louisville Gas
and Electric Company and Kentucky  Utilities  Company),  Southern Illinois Power
Cooperative,  Southern  Indiana  Gas & Electric  Company,  Wabash  Valley  Power
Association and Wisconsin  Electric Power Company.  MISO is expected to commence
operations in mid-2001.

     As presently  constituted  (excluding the NSP companies and SPS), MISO will
have a service territory that includes portions of Illinois,  Indiana, Kentucky,
Michigan,  Missouri,  Ohio and Wisconsin and two regional  reliability  councils
(East Central Area Reliability  Coordination Agreement ("ECAR") and Mid-American
Interconnected Network ("MAIN")). MISO will control 45,000 miles of transmission
facilities which represent  approximately  $6.5 billion in capital  investments,
and approximately 70,000 MW of generation assets will be located within the MISO
region.  With the addition of the NSP  companies  and SPS,  MISO's  transmission
facilities will expand  significantly  to include  portions of Minnesota,  North
Dakota,  South Dakota,  Texas, New Mexico,  Oklahoma and Kansas,  and generation
assets in the MISO region will exceed 80,000 MW. Also, Alliant  Corporation,  on
behalf  of  Wisconsin  Power & Light  Company,  Interstate  Power  Company,  IES
Utilities,  Inc. and South Beloit,  Water, Gas and Electric Company,  is seeking
FERC approval to become a participant in MISO.

     On September 16, 1998, FERC conditionally approved the formation of MISO by
authorizing  the transfer of  jurisdictional  facilities  from the  Transmission
Owners to MISO, and accepting the MISO Tariff and MISO Agreement for filing./76

     with FERC by January 15, 2001  explaining how MISO has the  characteristics
     and  performs the  functions of RTOs as set out in the final RTO rule.  See
     Order No. 2000 at 31,223.

----------

     MISO will develop all necessary  operating  procedures  and have  authority
over approving transmission requests,  implementing  curtailment of transmission
or requiring  redispatch of  generation  with  transmission.  MISO's duties will
include  calculating  available  transmission  capability and maintaining  OASIS
information.  MISO will monitor  real-time data to determine whether any control
areas are experiencing generation capacity deficiencies.  MISO also will control
transmission  maintenance.  Integration of generation will be facilitated at the
MISO level through various  methods/77 and through  coordinating the maintenance
(outage  schedules) of generating  units to assure that they minimize the impact
on  transmission  capability.  Thus,  entities  participating  in the MISO  will
interconnect  and integrate their systems in a joint effort to promote  regional
deployment of certain operating functions, security and redispatch functions and
scheduling  functions so as to enhance  efficiencies  across this broad regional
market.

     In joining  MISO,  New NSP,  NSP-W and SPS will  transfer  control of their
respective  transmission  systems to MISO and become  subject to the MISO Tariff
and Bylaws.  Thus, like the tight power pool  arrangements that formed the basis
for  findings of  integration  by the  Commission  in UNITIL and  Conectiv,  the
transmission  facilities of these  entities will be under common  management and
control along with those of other MISO members.  Transmission  will be centrally
coordinated  so as to  maximize  transmission  capacity.  Further,  transmission
constraints will be alleviated through regional redispatch of generation so that
the system can  operate at maximum  efficiency.  Transmission  upgrades  will be
planned  on a  regional  basis to assure the most  economic  means of  relieving
constraints  over the  long-run  are  achieved.  The  greater  the  transmission
capacity,  the  greater  the ability  the NSP  companies  and the NCE  Operating
Companies will have to obtain low cost sources of generation throughout the MISO
region and to arrange for power transfers from one another.  Finally, removal of
rate pancaking  throughout the MISO regional tariff, which provides for a single
regional rate, will remove economic barriers in reaching more distant sources of
generation supply. Thus, the efficiency of centralized  transmission  management
and pricing will directly  create greater  purchasing  efficiencies in obtaining
power for Xcel's customers./78

----------
77   MISO will have some control over the generation of the Transmission Owners.
     As stated by the Transmission  Owners of MISO in their application to FERC,
     MISO will  possess  authority  over  generation  to the extent  "generation
     affects   transmission."  In  particular,   MISO  will  solve  transmission
     congestion  through  curtailments,  generation  redispatch  and  (as a last
     resort) load shedding.  MISO will use redispatch to prevent the curtailment
     of  scheduled  firm  and  network  transmission  service  and the  costs of
     redispatch will be shared among all load including bundled native load on a
     pro rata basis  rather than  directly  assigned  to  specific  transmission
     customers.  MISO  members  that own  generation  will be  required to offer
     redispatch service pursuant to cost-based rates on file with FERC, and MISO
     will select the  least-cost  option for  redispatch.  When requests for new
     firm service cannot be  accommodated  under current  operating  conditions,
     MISO will facilitate  transmission  capacity  reassignment (by posting bids
     electronically on a real-time basis) and transmission capacity expansion by
     generation  redispatch (by  identifying  generators  that could relieve the
     constraint  by  increasing  or  decreasing  their  output).  When a  system
     emergency arises, however, MISO will take whatever actions are necessary to
     maintain   the   reliability   of  the   Transmission   System,   including
     curtailments. MISO Order at 62,162.

78   As noted  previously,  this result was  recognized by FERC in its Order No.
     2000 at p. 31,174, where FERC stated: "A main reason that an RTO can expand
     the  marketplace  for  generation  to a  large  region  is  that an RTO can
     implement non-pancaked rates for each transaction. A wider area served by a
     single rate means more generation is economically available to any customer
     which means greater competition for energy."

----------

     The impact of  joining  MISO on  Applicants'  combined  operations  is best
demonstrated by way of an example.  Currently, NSP buys power from the market to
meet its customers'  energy needs. A key limiting factor in all purchases is the
need to arrange for and the associated  cost of  transmission.  It is common for
NSP to arrange a purchase  from the Cinergy hub,  which is a liquid  market that
permits  critical  hedging against  volatile price swings.  However,  because of
transmission  cost   differentials,   NSP  typically  finds  nearby  power  more
economical  by the time  delivery is  expected.  NSP then sells its  position in
Cinergy and buys from  neighboring  markets at a higher energy price but a lower
overall price (energy plus pancaked transmission).  Under MISO, NSP will be able
to keep and to take  delivery  from  Cinergy,  as there  will be no  incremental
transmission cost to make transmission  uneconomical.  With SPS in the same RTO,
the  purchase  could be made  jointly and  dispatched  to the entity  whose load
requirements  indicate  a  need  for  the  energy.  Again,  there  would  be  no
transmission price  differential,  and the power could flow freely to either NSP
or SPS. In this way, both operating companies achieve economies  associated with
access to low-cost  power as well as  efficiencies  in the  economic use of this
power supply. Without common MISO membership,  pancaked transmission rates would
create  differences  in the  ultimate  purchase  decision  that  would make such
coordinated  arrangements  more  difficult and less  efficient.  Moreover,  MISO
membership will permit the necessary  transmission  arrangements to be made with
MISO as the sole transmission provider.

     Accordingly,  when the NSP companies and SPS become  members of MISO,  they
will be able to transmit power between their two systems at nonpancaked  rates -
specifically, at an incremental cost which is the same per unit cost involved in
shipping power within their respective systems./79 Since all market participants
in MISO can similarly  move power at no additional  cost of transport,  the MISO
Tariff makes choice of power supply across a broad region economically  feasible
for the Applicants.  As this occurs,  Applicants' integration of generation will
be efficiently  accomplished in the  marketplace,  through the ability to access
potentially  100,000  MW of  generating  capacity  rather  than  merely  seeking
opportunities to exchange power with one another. When the NSP companies and SPS
believe  such  opportunities  exist,  they will  successfully  lower their total
energy costs to customers through their joint participation in energy markets.

-----------
79   There are gaps in the  contiguous  borders of MISO;  however,  any  charges
     incurred for flows across those borders would produce a relative small cost
     differential  when compared with a traditional rate pancake across multiple
     service  territories;  as a  consequence,  the  transactions  will still be
     economically  feasible.  In fact, there is currently an intervening utility
     between SPS and MISO. As explained  below, SPS intends to obtain a contract
     path  across  the   intervening   utility   service  area  so  that  it  is
     interconnected  directly with MISO,  although the need for this path may be
     obviated in the event that the presently  contemplated  combination of MISO
     and SPP reaches fruition.

----------

     As noted  above,  Applicants  anticipate  that  MISO  will  have  attracted
additional members by the time it becomes fully  operational,  which will permit
SPS to be directly  interconnected with MISO through intervening utilities.  For
example,  if the Southwest  Power Pool (i.e.,  SPP) becomes part of MISO,  there
would  be  a  contiguous   MISO   transmission   region  between  SPS  and  NSP.
Alternatively,  if MAPP  members  join MISO  consistent  with recent  agreements
between the two, there may be a direct link to Sunflower  Electric  Cooperative,
Inc. through the  Holcomb-Potter  segment of the tie-line if Sunflower and other
directly connected members elect to participate in MISO.  However,  in the event
that SPS does not become directly  interconnected  with another MISO member, SPS
intends to obtain a firm, 200 MW bi-directional transmission path from the point
at which its system  interconnects  with  Public  Service  Company  of  Oklahoma
("PSO") to the point at which PSO interconnects  with Ameren and MISO. This path
is referred to herein as the "MISO Interconnection." SPS has contracted for this
path from the SPP under its open-access transmission tariff.

     Absent anticipated changes that result in a direct interconnection  between
SPS  and  another  MISO  member,  Applicants  will  implement  their  plans  and
agreements  already  executed  for the MISO  Interconnection.  In the event that
Applicants  need to  establish  the MISO  Interconnection,  they will attempt to
enter  into  arrangements  with PSO or the SPP to  facilitate  third-party  use.
Specifically, they will attempt to make arrangements so that the interconnection
path will be treated as part of SPS's system,  and  therefore  subject to MISO's
tariff.  Transmission  customers  would then be able to arrange service over the
path through MISO.

                                    * * * * *

     The foregoing discussion was intended to provide background and overview of
how NSP and NCE will be integrated through a contract path and through the Joint
Operating  Agreement and how that  integration  will be facilitated  through the
common  membership  of the NSP  companies  and  SPS in  MISO.  Each of the  four
integration standards of Section 2(a)(29)(A) is discussed specifically below.

                         (a)     Interconnection

     The first requirement for an integrated electric utility system is that the
electric  generation  and/or   transmission   and/or   distribution   facilities
comprising  the system be  "physically  interconnected  or  capable of  physical
interconnection."   Historically,   the   Commission  has  focused  on  physical
interconnection  through  facilities  that the  parties  owned or, by  contract,
controlled./80 As early as 1978,  however,  the Commission  indicated that joint
participation   in  a  power   pool   could  be  the  basis  for  a  finding  of
integration./81  To date,  the  Commission  has  found  interconnection  through
memberships  in "tight" power pools and ISOs./82  These  findings are consistent
with the  recommendation  of the 1995  Study that the  Commission  "adopt a more
flexible  interpretation of the geographic and physical  integration  standards,
with more emphasis on whether an  acquisition  will be economical and subject to
effective regulation."

     as to what should be the future structure of the electric utility industry.
     We will not  undertake  to resolve  these  issues since they are beyond our
     mandate  in this case and  because  they are  within  the  province  of the
     Congress and the Department of Energy.").

82   See,  e.g.,  UNITIL Corp.,  supra  (interconnection  through  NEPOOL),  and
     Conectiv,  Inc.,  Holding  Co.  Act  Release  No.  26382  (Feb.  25,  1998)
     (interconnection  through PJM, Inc.).  See also Yankee Atomic Elec. Co., 36
     S.E.C. 552, 565 (1955); Connecticut Yankee Atomic Power Co., 41 S.E.C. 705,

     in a commonly-owned  nuclear power company and finding the  interconnection
     requirement  met  because  the  New  England   transmission   grid  already
     interconnected the companies).

----------

     The 1995 Report further recommended that the Commission should increasingly
rely on an acquisition's  demonstrated  economies and efficiencies,  rather than
upon physical  interconnection,  to meet the  integration  standard.  The Report
noted  that  the  1935  Act  provides  the  necessary  flexibility  and that the
application of the  integration  standards must be able to adjust in response to
changes in the state of the art. The Report concluded that it would be a logical
extension of prior  orders for the  Commission  to find that  wheeling and other
forms of sharing  power (such as  reliability  councils  and  proposed  regional
transmission  groups) also qualify as  interconnection.  This  recommendation is
particularly  significant in view of the recent RTO Order,  which will cause the
development  of regional  transmission  grids that will bring even more  distant
utilities closer together.

     As explained  above,  the NSP Electric System and the Primary System of NCE
will be  "physically  interconnected  or  capable of  physical  interconnection"
through membership in MISO and by means of the Northbound Path.

     The   Northbound   Path,   in  and  of  itself,   satisfies   the  physical
interconnection  requirement of Section 2(a)(29)(A).  The Commission in the past
"has reasonably  construed this requirement to be satisfied in cases...  'on the
basis of  contractual  rights  to use a  third-party's  transmission  lines...'"
Madison Gas and Electric Company v SEC, supra at 1340. See also Centerior, supra
(The physical  interconnection  requirements of [Section 2(a)(29)(A)] are met if
the two  service  areas  are  connected  by power  transmission  lines  that the
companies  have  the  right to use  whenever  needed.").  Dicta  in a series  of
Commission  decisions  states  that  contract  rights  cannot  be  relied  on to
integrate two "distant" systems. See, e.g., WPL Holdings,  Inc., Holding Co. Act
Release No.  26856 (April 14,  1998),  citing  UNITIL  Corp.,  supra;  Northeast
Utilities,  Holding Co. Act Release No. 25273 (March 15, 1991); Centerior Energy
Corp.,  supra. In the Applicants' view, it would be incorrect to interpret these
statements  to mean  that a firm  contract  path  might  not meet the  "physical
interconnection" requirement because of its length. In both UNITIL and Northeast
Utilities,  the  Commission  explained that the reason a contract path might not
"integrate"  two  distant  utilities  was due to the  "single  area  or  region"
requirement of Section 2(a) (29)(A). UNITIL, supra at n.30; Northeast Utilities,
supra at n.75. The Commission did not hold in any of these cases that the length
of a firm  contract  path was relevant in  determining  whether the  "physically
interconnected  or capable of physical  interconnection"  requirement of Section
2(a)(29)(A) was met. Such a holding would be contrary to the literal language of
Section  2(a)(29)(A),  and would ignore both the  technological  and  commercial
developments  in the industry that have occurred since the enactment of the Act.
The  Commission  recently  confirmed the  Applicants'  view on this issue in the
AEP/CSW Order, in which the Commission  stated: "We did not hold in any of these
prior  cases that the  length of a contract  path was  relevant  in  determining
whether the interconnection  requirement of Section 2(a)(29)(A) was met. Such an
approach  would be  inappropriate  in view of the  express  language  of Section
2(a)(29)(A) as well as technological and commercial  developments that have made
feasible the transmission of power over longer distances."

     NSP and NCE also will be "physically  interconnected or capable of physical
interconnection"  through their common membership in MISO.  Commission precedent
supports a finding of  interconnection  through an ISO such as MISO./83 In 1992,
the Commission  approved the merger of UNITIL Corporation with Fitchburg Gas and
Electric  Light  Company,  based on their  common  membership  in  NEPOOL,/84  a
regional  power pool that was the basis for a FERC  approved ISO and  associated
power exchange./85 UNITIL and Fitchburg were not connected through  transmission
lines that they owned. Rather, as the Commission noted in its order:

----------
83   Such findings would also appear  consistent  with  Applicants'  position in
     their FERC  application  and the  following  statement  in the FERC  Merger
     Order:  "Upon  joining  MISO  following  consummation  of the merger,  Xcel
     Energy's  northern zone,  consisting of New NSP Utility and NSP-W,  will be
     physically  interconnected  with  its  southern  zone,  consisting  of SPS,
     through the transmission system of MISO."

84   New England Power Pool, 79 FERC P. 61,374 (1997);  New England  Power Pool,
     83 FERC P. 61,045 (1998).

85   MISO differs from how NEPOOL was initially structured as a tight power pool
     in that NEPOOL  provided for centralized  dispatch,  within a single routed
     area, of the generating assets of the NEPOOL members. However, as explained
     below,  this  difference  is not  relevant  to  whether  two  entities  are
     "physically interconnected or capable of physical interconnection."

----------

          Access to and use of the regional transmission network, which is owned
          by the  larger  New  England  utilities,  is  provided  by the  NEPOOL
          Agreement and by transmission  rate schedules and contracts filed with
          the Federal Energy Regulatory Commission.

          In this matter,  the Companies are indirectly  interconnected  through
          NEPOOL-designated    transmission   facilities   ("PTF")   and   other
          nonaffiliate  transmission facilities pursuant to the NEPOOL Agreement
          and  other  separate  agreements  with  nonaffiliate  companies.   The
          Commission  has  previously  found a system to be "capable of physical
          interconnection"   on  the  basis  of  contractual  rights  to  use  a
          third-party's transmission lines.

          This  matter  differs  from  prior  orders  in that  there  will be no
          particular  line through  which  transfers of power will be made among
          the Companies. Instead, power will be delivered through a nonaffiliate
          system  and a  transmission  charge  will be paid to the  owner of the
          facilities.  On the facts of this matter,  the Commission is satisfied
          that the Companies' contractual  arrangements for transmission service
          establish  that the UNITIL  electric  system will satisfy the physical
          interconnection requirement of the Act.

     With respect to the "other separate agreements with nonaffiliate companies"
described  above, the Commission by footnote  explained that Fitchburg  obtained
primary  transmission service from New England Power Company ("NEPCO") under the
NEPOOL  Agreement and through  NEPCO's FERC Tariff Number 3, which  provided for
non-firm service.  The Commission went on to note that Fitchburg was eligible to
use NEPCO's FERC Tariff No. 4/86 should  Fitchburg and UNITIL Power conduct more
power  sales or swaps.  In 1998,  based on  UNITIL,  the  Commission  found that
Delmarva  Power & Light  Company and  Atlantic  Energy,  Inc.  met the  physical
interconnection   requirements  of  Section  2(a)(29)(A)  through  their  common
membership in PJM Interconnection,  LLC ("PJM"), which was a regional power pool
and the first FERC-approved, operational ISO./87 Conectiv, Inc., Holding Co. Act
Release No. 26832 (February 25, 1998).

     The facts of this case similarly establish physical  interconnection  under
the UNITIL  precedent  and its  progeny.  Access by NSP and SPS to the  regional
transmission  network of MISO will be  provided by the MISO  Agreement  and MISO
Tariff,  which have been filed with FERC. Also, like UNITIL Power and Fitchburg,
NSP and SPS will have "other separate agreements with nonaffiliate  companies" -
namely;  the firm Northbound Path for 100 MW, and the nonfirm  arrangements that
Applicants may arrange as described below under  "Coordination."  In particular,
MAPP has an  open-access  transmission  tariff,  Schedule F, that may provide an
alternative path for transactions  between SPS and the NSP companies.  Moreover,
in the  present  case  and like  UNITIL,  "power  will be  delivered  through  a
nonaffiliate system" (i.e., MISO) and "a transmission charge will be paid to the
owner of the facilities". As noted above, MISO will have functional control over
the  transmission  systems of NSP, NSP-W,  SPS and other members of the MISO. As
was the case in UNITIL, the NSP companies and SPS will be able to readily obtain
transmission  services at non-pancaked  rates to exchange energy with each other
or to access the market  collectively  as either a buyer or a seller.  For these
reasons,  Applicants  believe that the Xcel Electric  System will be "physically
interconnected or capable of physical interconnection."

     As shown by Exhibit E-13, the powers and  responsibilities of MISO over the
transmission  assets of members  of MISO will be  virtually  identical  to those
today of  NEPOOL  and PJM  over  the  transmission  assets  of their  respective
members. Applicants note that MISO differs from NEPOOL in UNITIL and from PJM in
Conectiv in that NEPOOL and PJM were both "tight" power pools at the time of the
Commission's  decisions,  in that the generation assets of all members of NEPOOL
and PJM were centrally  dispatched and  controlled.  Applicants  acknowledge the
relevance of generation control for purposes of evaluating whether the system is
operated as "a single  interconnected  and  coordinated  system"  under  Section
2(a)(29)(A),  but do not  believe it is  relevant  as to  whether  the system is
"physically interconnected or capable of physical interconnection."/88

     55.

87   Pennsylvania  - New Jersey -  Maryland  Interconnection,  81 FERC P. 61,257
     (1998).

88   The relationship between physical interconnection and coordinated system is
     examined in The North American Co., 11 S.E.C.  194, at 241-42  (1942).  The
     only physical  interconnection between four small service areas and a North
     American  subsidiary,  Illinois  Iowa Power  Co.,  was  through  facilities
     operated by Central  Illinois Public Service Co., a nonaffiliated  company.
     The small  properties  were held to be physically  interconnected  with the
     subsidiary but not part of a coordinated  system because most or all of the
     power for sale in these service areas was purchased  from Central  Illinois
     and there was no  central  control:  "Thus,  even  though we find  physical
     interconnection  exists or may be effected,  evidence is necessary  that in
     fact the isolated territories are or can be so operated in conjunction with
     the  remainder  of the system that  central  control is  available  for the
     renting of  power."  Moreover,  as  previously  noted,  NEPOOL and PJM have
     restructured into ISOs. Indeed,  both organizations have established or are
     in the process of establishing associated power exchanges.

----------

                         (b)     Coordination

     Historically,  the  Commission  has  interpreted  the  requirement  that an
integrated electric system be economically operated under normal conditions as a
single  interconnected  and  coordinated  system,  "to  refer  to  the  physical
operation  of  utility  assets as a system in which,  among  other  things,  the
generation and/or flow of current within the system may be centrally  controlled
and allocated as need or economy directs." See, e.g.,  Conectiv,  supra,  citing
The North American  Company,  Holding Co. Act Release No. 3466 (April 14, 1942),
aff'd, 133 F.2d 148 (2d Cir. 1943), aff'd on constitutional issues, 327 U.S. 686
(1946). The Commission has noted that, through this standard, Congress "intended
that  the  utility  properties  be so  connected  and  operated  that  there  is
coordination  among all parts,  and that those parts bear an integral  operating
relationship to one another." Id., (citations  omitted).  Applicants submit that
the  coordination  requirement is satisfied,  as evidenced by the AEP/CSW Order,
through  such  measures  as  coordinated  generation   operations;   coordinated
transmission  operations,  coordinated  marketing  efforts,  both as a buyer and
seller of electricity;  the integration of  administrative  and general services
and programs;  and gas/electric  convergence  type measures,  which will lead to
lower costs for gas as a fuel for the generation of electricity.

     This is not a  matter  of  first  impression.  Nearly  a  decade  ago,  the
Commission found, and the courts agreed, that the coordination requirement could
be  satisfied  even if power  never  flowed  between  two  parts of the  system.
Environmental Action, Inc. v. SEC, 895 F.2d 1255 (9th Cir. 1990).  Environmental
Action  involved  the  acquisition  by a holding  company of an  interest  in an
electric generating plant ("GenCo"). The intervenors argued that the acquisition
did not satisfy the standards of the 1935 Act because,  among other things,  the
system's  existing  electric utility company  ("UtilCo") had represented that it
might  purchase up to twenty  percent of GenCo's  capacity  if, and only if, the
price of such power was  competitive  in the market.  The Court of Appeals noted
that the GenCo  might not  purchase  any of  GenCo's  output  but,  nonetheless,
concluded that the Commission had correctly found that UtilCo and GenCo could be
operated as part of a coordinated system,  within the meaning of the Act. Id. at
1264-65,  citing Electric Energy, Inc., Holding Co. Act Release No., 13871 (Nov.
28, 1958) (the companies  sponsoring the construction of a generating plant only
pledged to buy any surplus  energy  remaining  after the plant had  supplied the
needs of the major purchaser, a nonaffiliated government agency). More recently,
the Commission found similar types of coordinated operational and administrative
functions  to  constitute  "de facto"  integration.  Sierra  Pacific  Resources,
Holding  Co. Act  Release  No.  27054  (1999).  Moreover,  the  coordination  of
administrative  functions and joint marketing activities were crucial factors in
the Commission's  determination that the coordination  requirement was satisfied
in Sempra and NIPSCO.

     Moreover, in applying the integration standard, the Commission looks beyond
simply the  coordination of the generation and  transmission  within a system to
the coordination of other activities. See, e.g., General Public Utilities Corp.,
Holding Co. Act Release No. 13116 (Mar. 2, 1956)  (integration  is  accomplished
through  power  dispatching  by a central  load  dispatcher  as well as  through
coordination  of  maintenance  and  construction  requirements);   Middle  South
Utilities,  Inc., Holding Co. Act Release No. 11782 (Mar. 20, 1953), petition to
reopen  denied,  Holding Co. Act Release No. 12978 (Sept.  13, 1955),  rev'd sub
nom.  Louisiana  Public  Service  Comm'n v. SEC,  235 F.2d 167 (5th Cir.  1956),
rev'd, 353 U.S. 368 (1957),  reh'g denied,  354 U.S. 928 (1957)  (integration is
accomplished  through an  operating  committee  which  coordinates  not only the
scheduling of generation and system  dispatch,  but also makes and keeps records
and necessary reports,  coordinates  construction  programs and provides for all
other  interrelated  operations  involved in the  coordination of generation and
transmission);  North American Company,  Holding Co. Act Release No. 10320 (Dec.
28, 1950) (economic  integration is  demonstrated by the exchange of power,  the
coordination  of future power demand,  the sharing of extensive  experience with
regard to  engineering  and other  operating  problems,  and the  furnishing  of
financial aid to the company being acquired). See also NIPSCO, supra (functional
merger of Bay States and NIPSCO gas supply  department  through NIPSCO Services,
"a service  company  subsidiary of NIPSCO that provides  financial,  accounting,
tax,  purchasing,  natural gas portfolio  management,  and other  administrative
services to associate companies.")

     Applicants will satisfy the coordination requirement in several ways.

     First,  in light of the  developments  that have  occurred in the  electric
utility  industry and the  regulatory  framework  that applies to it, which have
been detailed above,  the coordination of utilities can occur through the market
and contractual  arrangements.  The Joint  Operating  Agreement will provide the
contractual  operating  framework for the Xcel Operating Companies to coordinate
and transact with each other.

     Under the  agreement,  the generating  systems of the Xcel Electric  System
will  be  operated  as  a  single   interconnected   and   coordinated   system.
Specifically,  New Century Services, as agent for the Operating Companies,  will
coordinate  the planning,  operation  and  maintenance  of  generating  capacity
resources and the dispatch of electricity  throughout the combined system of NSP
and NCE. This will be accomplished  through a central  generation control center
that,  through a common software system,  will direct the dispatch of the entire
Xcel  Electric  System.  Under  this  arrangement,  the system  dispatcher  will
dispatch the generation  units of the Xcel Operating  Companies and those plants
under long-term contract to which the companies effectively dispatch generation,
as  needed  to meet  native  load and will  arrange  for  economy  energy  sales
(provided for in Schedule B of the Joint Operating  Agreement) between Operating
Companies  where such sales will  lower the  operating  costs of the  purchasing
Operating Company.  Although such dispatch will be facilitated by the completion
of the  tie-line  between  PSCo and SPS,  it will be  possible  to perform  such
dispatch and exchange  power under the Joint  Operating  Agreement even prior to
the completion of the tie-line. New Century Services will be able to obtain both
firm  (mostly  short-term)  and non-firm  transmission  between the PSCo and SPS
systems needed to engage in transactions  under the Joint  Operating  Agreement,
once it becomes  effective.  For example,  in the past,  PSCo and SPS  exchanged
power over a transmission tie owned by Public Service Company of New Mexico. The
current  transmission  and exchange of power between PSCo and SPS is facilitated
by their  participation  in the Western  Systems Power Pool ("WSPP"),  which, as
noted previously, is an economic power pool that operates an electronic bulletin
board and acts as a clearinghouse  for bulk power  transactions  among more than
ninety member utilities and marketers./89

     To allay any  concerns  that  state  commissions  and FERC may  have,  such
intra-system  sales will not be made if the purchasing  Operating  Company has a
better purchase opportunity, or the selling Operating Company has a better sales
opportunity.  Schedule A of the Joint Operating  Agreement likewise provides for
short-term   capacity  and  associated   energy  sales  between  Xcel  Operating
Companies,  subject to the same limitations.  The Joint Operating Agreement also
provides for joint generation  planning and the common procurement of resources,
although  again the  agreement  addresses  potential  state  concerns  by making
explicit  that  any  resource   additions  will  comply  with  applicable  state
procurement requirements. Additionally, the Joint Operating Agreement also vests
the agent,  New Century  Services,  with the  responsibility  of arranging joint
sales and purchases of electricity,  as described below, and makes provision for
the  allocation  of  associated  costs  and  revenues./90  The  Joint  Operating
Agreement,  with its protections,  also will benefit  customers as more and more
power is purchased  from the market.  Currently,  both NSP and PSCo are capacity
short and will have opportunities to coordinate contracting of purchases to meet
the energy needs of their  customers.  The Joint Operating  Agreement will allow
joint procurement to take advantage of weather and economic diversity as well as
scheduling of plant outages.

----------
89   While  the  completion  of the  tie-line  between  PSCo and SPS will  fully
     integrate  their two systems,  Applicants  note that PSCo and SPS have been
     operating on a  coordinated  basis since the  completion of their merger in
     1997  that  resulted  in the  formation  of NCE.  As stated in the Form U-1
     relating to the  combination  of SPS and PSCo (File No.  70-8787),  SPS and
     PSCo estimated net savings from their  combination  over a ten-year  period
     commencing  in 1997 in excess of $500  million  exclusive  of savings  that
     would  result from the  tie-line.  These  savings  were to be derived  from
     combined corporate  programs,  joint procurement of fuel and non-fuel items
     and labor cost savings.  NCE is on target to achieve these savings.  Today,
     through New Century  Services and a joint electric trading  operation,  SPS
     and PSCo are  being  run on a  combined  basis,  with the only  significant
     exception  being  that  their  generating  assets  are  not  being  jointly
     dispatched  on  an  economic  basis.  Currently,  PSCo  and  SPS  load  and
     generation  data is located in Denver where  traders can evaluate  purchase
     and sale decisions to optimize  generation  assets.

90   This philosophy is consistent with the treatment of affiliate  transactions
     involving   non-power  goods  and  services,   which  are  subject  to  the
     Commissions'  jurisdiction  under  Section 13 of the Act. See,  e.g.,  Rule
     88(a)  (service  companies  required  to be so  organized  as to be able to
     provide services,  construction,  or goods "at a reasonable saving over the
     cost of  comparable  services or  construction  performed  or goods sold by
     independent persons").

----------

     Second,  the  Xcel  Operating   Companies  will  coordinate  through  joint
marketing  efforts,  both  as  a  buyer  and  seller.  System  dispatchers  will
continually  monitor  the  generation  needs  and  capacity  of the  NSP and NCE
systems.  This will include the NSP companies,  SPS and PSCo. The Xcel Operating
Companies  already have the ability to reach common suppliers,  purchasers,  and
trading  hubs in various  combinations.  The rapidly  evolving  wholesale  power
markets  surrounding the energy industry will allow NSP and NCE to operate their
generation assets as a single system by buying and selling power to decrease the
overall  production  costs of the two systems.  The diversity of weather,  time,
fuel supply and  localized  economic  conditions  will create  opportunities  to
allocate resources more efficiently.  This can be accomplished  without the need
to actually move power from the NSP system or NCE system to the other  company's
system.  Power can be delivered to and from the systems by third  parties  using
their  transmission  systems.  The 100 MW Northbound  Path will  facilitate  the
ability of the entities to  coordinate  their systems by assuring the ability to
move power even when there are transmission constraints.

     The  Northbound  Path is not the only  means  for NSP and NCE to  engage in
these efforts:  the NSP companies,  SPS and PSCo presently trade in other common
markets,  which can be accessed post-merger.  For example, the NSP companies and
NCE  Operating  Companies  both hold  capacity  contracts  with  Basin  Electric
Cooperative.  In 1998,  NCE  purchased  200MW of capacity from the Laramie River
Station.  PSCo recently  added an additional 136 MW. NSP contracted for 65 MW of
seasonal  capacity  from Basin as well as entering  into an ongoing  energy only
agreement which allows NSP to purchase system energy from Basin. Because Laramie
River  Station  is  located  at the  intersection  of the  Eastern  and  Western
Interconnections,  it is  equipped  to sell  power  in both  directions.  In the
future,  joint purchases could be made and dispatched to the operating companies
that would  provide  the greater  benefit.  Weather  diversity  would make these
purchases  more  economically  efficient  as changes  in daily and  hourly  load
forecasts can be accommodated by joint purchasing and coordinated  dispatch.  In
addition to Basin,  both PSCo and NSP have made significant  purchases from WAPA
in the past. In 1997, NSP purchased 252,332 MWh from WAPA. During this same time
period,  the NCE  Operating  Companies  purchased  559,121 MWh from WAPA.  Given
WAPA's location on the border of the Eastern and Western Interconnects,  it will
serve as a market for coordinated trading activities.  This ability to diversify
supply  over a  broader  region  with  diverse  weather  and  time  zones is how
companies  can  best  achieve  the  benefits  of  economic   integration   in  a
market-based  commodity  like  electricity.  The NSP companies and NCE Operating
Companies also anticipate  making use of the burgeoning  power markets and their
associated volatility to maximize efficiency and coordination on their systems.

     Again, the Joint Operating Agreement provides the framework for these types
of  activities.  Pursuant  to  Schedule  C  (System  Sales  and  Purchases,  and
Off-System   Marketing),   New   Century   Services   as  the  Agent  will  have
responsibility  to engage in wholesale sales and purchases on behalf of the Xcel
Operating   Companies  on  an  individual  company  and  collective  basis.  The
coordination of these activities under the Joint Operating Agreement is expected
to result in savings for the Xcel Operating Companies and their customers./91

----------
91   The Joint Operating  Agreement (Schedule D) also vests New Century Services
     as the Agent under the Joint  Operating  Agreement  with the  authority  to
     acquire  the  necessary   transmission  services  for  wholesale  marketing
     activities with non-affiliates and the system transactions described above.

----------

     These  marketing  efforts  will  be  further   facilitated  by  the  common
participation  of the NSP  companies and SPS in MISO.  For example,  NSP and NCE
will be able to use the  diversity  between  their  systems  to buy and  sell in
common MISO markets such as Ameren to optimize their use of this market, acting,
in effect, like their own trading hub.

     Third,  as explained  further below,  the Xcel Operating  Companies will be
able to achieve  efficiencies in the management of their natural gas portfolios.
Because  PSCo,  SPS,  and NSP use  natural gas to  generate  electricity,  these
efficiencies  are  expected  to  translate  to lower  cost for gas as a fuel for
electric production, which will benefit electric customers.

     Fourth, the combined system in this matter will be coordinated in a variety
of ways beyond simply the coordination of the generation and transmission within
the system.  Among other things,  numerous operational matters and virtually all
administrative and general services will be performed for the Xcel System by New
Century Services.  In addition,  the accounting functions of the combined system
will be prepared and consolidated  through the use of a single system. Xcel will
have a single accounting  organization which will be managed by a single team in
one or more locations.  The  coordination and integration of the combined system
is expected to be further  achieved  through the coordination and integration of
information  system  networks;  customer  service;   procurement  organizations;
organizational  structures for power generation,  energy delivery (which include
transmission)  and  customer  relations;  and  support  services.  Many  of  the
foregoing  functions  will be  performed  by various  business  units within New
Century  Services.  For  example,  the Xcel  Energy  Markets  unit will have the
responsibility  under the Joint  Operating  Agreement  of  conducting  the joint
marketing and trading for all generating  resources of PSCo, SPS, NSP and NSP-W.
The  Enterprise  Business unit of New Century  Services,  with the assistance of
Xcel's  chief  financial  officer,   will  centralize  asset  management  policy
decisions,  provide an integrated approach to financial decisions and develop an
appropriate  allocation of resources between new capital  investment and routine
operation.   The  Xcel  Energy   Delivery  unit  will  include  a   transmission
organization,  a distribution  organization,  customer service  organization,  a
planning and budgeting  services  group,  and a customer and community  services
organization.  The  Corporate  Development  unit of New  Century  Services  will
provide  direction  to the  Xcel  System  in  areas  such as  integration,  best
practices and business re-engineering.

     Also,  as has already been  discussed,  the  operation of the  transmission
systems of the NSP companies and SPS as a single  interconnected and coordinated
system will be enhanced  through joint  membership  and  participation  in MISO.
Among other  things,  MISO will  develop  operating  procedures  and  schedules,
approve transmission  requests and direct the operation of the transmission grid
for all MISO participants. MISO also will coordinate maintenance and planning of
the transmission  facilities as well as certain generation  functions within the
MISO system.  This degree of coordination and integration of transmission assets
is  comparable to that  presented to, and accepted by, the  Commission in UNITIL
and Conectiv,  supra. Moreover, the availability of transmission under MISO will
provide the means to  coordinate  operations  and engage in the joint  marketing
efforts that are described above./92

----------
92   Section  2(a)(29)(A) might appear to require that the holding company,  and
     not a  third-party  such as MISO,  must  coordinate  the  operations of the
     integrated system.  However,  such an interpretation of Section 2(a)(29)(A)
     would be  incorrect  as shown by  UNITIL in which  the  Commission  stated:
     "While the definition reflects an assumption that the holding company would
     coordinate  the  operations of the  integrated  system,  the Commission has
     recognized  that  "Congress  did not intend to impose  rigid  concepts  but
     instead expressly included flexible  considerations" to accommodate changes
     in the electric  utility  industry.  Thus,  the  Commission  has considered
     advances  in  technology  and the  particular  operating  circumstances  in
     applying  the  integration  standards.   Most  recently,  in  its  decision
     approving the  acquisition of PSNH by Northeast  Utilities,  the Commission
     noted that "the operation of the generating and transmitting  facilities of
     PSNH and the Northeast  operating  companies is  coordinated  and centrally
     dispatched under the NEPOOL Agreement."  Accordingly,  we conclude that the
     combined  electric  utility  assets  in  this  matter  may be  economically
     operated as a single  interconnected  and  coordinated  system  through the
     Companies' participation in NEPOOL."

----------

     As indicated by the language under Section 2(a)(29)(A) that the coordinated
system be "economically  operated," the Commission  further analyzes whether the
coordinated  operation of the system results in economies and efficiencies.  The
question  whether a combined system will be economically  operated under Section
10(c)(2) and Section  2(a)(29)(A) was recently addressed by the Court of Appeals
in Madison Gas and Electric  Company v. SEC, 168 F.3d 1337 (D.C.  Cir. 1999). In
that case,  the court  determined  that in  analyzing  whether a system  will be
economically  coordinated,  the focus must be on whether the  acquisition  "as a
whole" will "tend toward  efficiency  and economy." Id. at 1341. The Merger will
clearly  meet this  standard.  As explained  in Item 3.C.2.  below,  NSP and NCE
estimate  that the net savings  from the Merger will exceed $1.1 billion over 10
years.

     In the recent AEP/CSW Order, the Commission found that the combined AEP and
CSW electric  systems (the "New AEP System") met the requirement of economic and
coordinated operation under Section 2(a)(29)(A). In response to an argument from
an intervenor that the New AEP System would be coordinated  solely through a 250
Mw contract path,  the  Commission  noted that the contract path was only one of
several  ways that the proposed  combined  system  would be  coordinated  and by
footnote explained:

     ". . . the Umbrella  Agreements will permit control and coordination of the
     New AEP System.  Our finding of economic and coordinated  operation is also
     supported by other proposed measures:  potential  intrasystem  transfers of
     capacity  and  energy;  joint  trading and  marketing;  and  corporate  and
     administrative coordination."

AEP/CSW  Order at fn. 86. Each of these  factors  exists in the present case. In
addition to the 100 Mw Northbound Path, the Joint Operating Agreement,  like the
Umbrella Agreement in the AEP/CSW Order, will permit control and coordination of
the Xcel  Electric  System.  There will be  potential  transfers of capacity and
energy and joint trading and marketing among PSCo, SPS, NSP and NSP-W.  Finally,
numerous corporate,  administrative and operational matters will be performed on
behalf of the Xcel system by NCE Services.

     In  short,  all  aspects  of the  combined  system  will be  centrally  and
efficiently planned and operated.  As with other merger applications approved by
the  Commission,  the  combined  system  will be capable  of being  economically
operated as a single  interconnected  and coordinated  system as demonstrated by
the variety of means through which its operations  will be  coordinated  and the
efficiencies and economies expected to be realized by the proposed transaction.

                         (c)     Single Area or Region

     As required by Section  2(a)(29)(A),  the  operations  of the Xcel Electric
System  will be  confined  to a "single  area or region in one or more  States."
While the terms "area" and "region" are not defined in the 1935 Act, the "single
area or region"  requirement  does not  mandate  that a system's  operations  be
confined to a small  geographic  area or a single  state./93 The  Commission has
specifically  found that the  combining  systems need not be contiguous in order
for the  requirement  to be met./94  Rather,  the  Commission has found that the
single  area or region test  should be applied  flexibly  when doing so does not
undercut the policies of the 1935 Act against  "'scatteration' -- [that is,] the
ownership of widely dispersed utility properties which do not lend themselves to
efficient  operation and effective state  regulation."  NIPSCO,  supra (applying
single area or region  requirement with respect to gas utility system);  accord,
Sempra, supra./95

----------
93   In considering  size, the  Commission has  consistently  found that utility
     systems  spanning  multiple  states  satisfy  the  single  area  or  region
     requirement  of the 1935  Act.  For  example,  the  Entergy  system  covers
     portions of four states  (Entergy,  supra),  the Southern  system  provides
     electric  service to  customers in portions of four states  (Southern  Co.,
     Holding Co. Act  Release No.  24579 (Feb.  12,  1988)),  and the  principal
     integrated  system of NCE covers  portions of five states  (with all of its
     electric  operations  serving  customers  in six  states)  (1997 NCE Order,
     supra).  As early as 1945,  the  Commission  found that the  operations  of
     American Electric Power in seven states were confined to a single region or
     area. American Gas and Electric Co., Holding Co. Act Release No. 6333 (Dec.
     26, 1945).

94   See, e.g., Conectiv, supra; cf. 1997 NCE Order, supra (integration test was
     met  where  entities  planned  to  build a 300  mile  transmission  line to
     interconnect the systems which operated in noncontiguous territories).

95   In Gaz  Metropolitain,  Inc., the  Commission  agreed that a single area or
     region could include areas across  international  borders.  Holding Co. Act
     Release No. 26170 (Nov. 23, 1994).

----------

     Moreover,  the Staff has  recommended  that the  Commission  "interpret the
'single  area  or  region'  requirement  flexibly,   recognizing   technological
advances,  consistent  with the purposes and provisions of the Act" and that the
Commission  place "more emphasis on whether an acquisition  will be economical."
1995  Report at 66, 69. The Staff has  recognized  that  "recent  institutional,
legal and technological  changes . . . have reduced the relative importance of .
 . . geographical  limitations by permitting  greater  control,  coordination and
efficiencies" and "have expanded the means for achieving the interconnection and
economic  operation and  coordination of utilities with  non-contiguous  service
territories."  1995  Report at 69. It has also  recognized  that the  concept of
"geographic  integration"  has been affected by  "technological  advances on the
ability to transmit  electric energy  economically  over longer  distances,  and
other  developments  in the industry,  such as brokers and  marketers." Id. Such
advances and developments are breaking down traditional  boundaries and concepts
of regions.  The  Commission  has confirmed its support for the Staff's  Report,
citing, in particular,  the Staff's recommendation that the Commission "continue
to interpret the 'single area or region'  requirement  of [the 1935 Act] to take
into account technological advances." NIPSCO, supra; accord, Sempra, supra.

     The Applicants  believe that the Xcel Electric  system will satisfy "single
area or  region"  requirement.  The Xcel  Operating  Companies  all  have  their
electric  operations  in the  Mid-Continent  area of the United States in states
that  adjoin - Michigan,  Wisconsin,  Minnesota,  North  Dakota,  South  Dakota,
Wyoming,  Colorado, New Mexico, Texas, Oklahoma and Kansas. Three of the primary
Xcel Operating Companies (SPS, NSP and New NSP) will be part of MISO, which will
be tasked with operating the regional grid, and the other primary system,  PSCo,
will be directly interconnected upon completion of NCE's commitments in the 1997
NCE  Order.  An RTO,  such as MISO,  effectively  defines a region  from both an
operational and economic standpoint. To reiterate, FERC is promoting RTOs due to
operational and economic inefficiencies that presently exist. Generally, from an
operational  perspective,  RTOs will  place  transmission  services  in a larger
regional  market,  which  is  necessary  to  achieve  short-term  and  long-term
reliability,   including  the  authority  to  direct  transmission   maintenance
schedules  and to  redispatch  generation  to ensure the integrity and operation
efficiency of the electric grid.  The RTO will also ensure proper  evaluation of
ATC, proper  transmission  congestion  management and proper  management of loop
flows.  By virtue of common  membership in MISO, the electric  operations of the
NSP companies and SPS will be part of the same region.

     Likewise,   RTOs  create  an  economic  region  due  to  the  pancaking  of
transmission rates and the burden to transmission customers of having to arrange
service from multiple  providers that would otherwise  exist. The result is that
RTOs will likely  become the primary  trading  region for RTO members.  FERC has
recognized the key of RTOs in establishing a trading region among utilities:

     The Commission has long recognized that transmission pricing reform is most
     effectively  accomplished  on a  regional  basis.  An RTO  would  have  the
     geographic scope needed to eliminate pancaked transmission rates within its
     region. This would broaden the generation  market...thereby  fostering more
     competitive markets and lower prices./96

     MISO is organized to be extremely  effective in achieving  this  objective.
Quite simply,  joint  membership in MISO makes all of its members,  at the most,
one-wheel  away./97  That is, the  elimination  of pancaked  transmission  rates
throughout  the  MISO  region  will  create  a broad  wholesale  market  readily
accessible to all members.

----------
96   RTO NOPR,  FERC Stats & Regs at 33,716.  See also Order No. 2000 at 31,174,
     where FERC  stated:  "A main reason that an RTO can expand the  marketplace
     for generation to a large region is that an RTO can implement  non-pancaked
     rates for each transaction. A wider area served by a single rate means more
     generation is  economically  available to any customer  which means greater
     competition for energy."

97   In fact,  under the MISO  bylaws it may be  possible  for NSP and SPS to be
     part of a single zone in which case there would be no  incremental  cost of
     transmission  (or no wheel) for  exchanges of power between them.

----------

     Thus,  through a common RTO, the NSP  companies and SPS will be in the same
operational and economic  region.  These regions created by RTOs are larger than
those in the electrical regions of the past for a variety of reasons.  First, as
previously   discussed   the   technological   advances  and  additions  to  the
transmission  network that have occurred  since 1935 now permit trading to occur
over 1000 mile distances.  Second,  as explained in detail  previously,  a large
region is necessary to address the  inefficiencies  and inequities  that FERC is
seeking to remedy through RTOs.

     Moreover,  although  PSCo  will  not be in the  same RTO as SPS and the NSP
companies,  it  nonetheless  should  be  considered  to be in the same  economic
region,  in light of the historic pattern of trading with Basin  Cooperative and
WAPA as described above. Upon the completion of Phase II of the tie line, trades
into MAPP by PSCo will be further  facilitated,  and, more importantly,  because
the interconnection  will place PSCo on the border of MISO, PSCo will be able to
directly access the MISO region, including NSP, at non-pancaked rates.

     The conclusion  that the Xcel Electric System will constitute a single area
or region is further  supported by the logic of the  Commission's  definition of
"region"  used for purposes of its size  analysis  under  Section  10(b)(1).  In
Entergy,  supra,  the  Commission  adopted  the  applicants'  definition  of the
relevant region for purposes of Section 10(b)(1) to include themselves and those
electric  utilities directly  interconnected  with either or both, which, at the
time, were their most accessible  markets.  This region  consisting of utilities
within  "one-wheel" of the merging  utilities made sense in light of the barrier
that rate  pancaking  presented  in trying to access more  distant  markets.  In
today's  increasingly  competitive world, NSP and NCE do not operate as isolated
companies, and their geographic region should be analyzed in terms of their most
accessible  market,  which will be MISO.  With the elimination of rate pancaking
and with central control of their transmission assets in MISO, the Xcel Electric
system  will  primarily  compete  within and access the MISO  market and will be
within  "one  wheel"  of each  other  under  the MISO  Tariff.  At the time PSCo
interconnects  its system with SPS, it will be one-wheel  away from both SPS and
NSP thereby satisfying the test set forth in Entergy.

     The  Commission's  recent  decision in Sempra Energy is also relevant for a
commodity business such as the evolving electricity  industry. In that decision,
the SEC  approved  Sempra's  acquisition  of a 90 percent  interest  in Frontier
Energy  LLC of North  Carolina  and  considered  the  combined  system  to be an
integrated  system  under the  Act./98 In that  decision  the SEC  affirmed  the
existence of a national natural gas commodity market.  The SEC pointed out that,
when the Act was drafted in the 1930s, the common source  requirement  meant the
same source at the city gate.  Now,  however,  with the changing gas market,  it
means  obtaining  gas from the same  supply  basins.  Thus,  even though the two
systems in Sempra were 3,000 miles apart, the SEC said that its decision did not
undercut  the Act  because  the  acquisition  did not  raise the  concerns  that
prompted its enactment.

----------
98   Sempra Energy, Holding Co. Act Release No. 26890 (June 26, 1998).

----------

     The logic of this  decision is  directly  applicable  to  electric  mergers
because  the  electric  industry  is in  rapid  transition  to  becoming  both a
commodity  market  and  an  extended  retail  consumer  services  industry.   As
demonstrated  above, there are numerous instances where NCE and NSP purchase and
sell  commodity  energy in the same market.  These  instances will increase with
continued growth in wholesale electric power market competition.  In Sempra, the
SEC concluded that because Sempra and the North Carolina distribution company it
was acquiring  purchased some natural gas from the same supply basin,  they were
integrated  utilities for Section 11 purposes under the Act. Extending the logic
of Sempra to the evolving electricity markets, the systems of NSP and NCE are in
a "single area or region"  because  they  purchase and sell energy into the same
regional and national commodity markets.

     Moreover,  the  combination  of the NSP  companies  and  the NCE  Operating
Companies does not contravene the policy of the Act against "scatteration" - the
ownership of widely dispersed utility  properties that do not lend themselves to
efficient  operation.  As stated in Sempra,  supra, "The Act is directed against
the growth and extension of holding companies [that] bear no relation to economy
of  management  and operation or the  integration  and  coordination  of related
operating  properties".  In the AEP/CSW  Order,  the  Commission  found that the
combined  operations  of the AEP and CSW  systems  would be confined to a single
area or region  due to the  presence  of the  following  four  factors:  (i) the
combined  system  would  be  interconnected  and  susceptible  of  economic  and
coordinated  operations,  (ii) no adverse finding on anticompetitive grounds was
necessary  under Section  10(b)(1),  (iii) the size of the combined system would
not impair efficient operation,  localized  arrangement or effective regulation,
and (iv) the merger would result in economies  and  efficiencies  under  Section
10(c)(2).  These same factors are present in this case. As  demonstrated  above,
the Primary  System of NCE and the electric  operations of NSP and NSP-W will be
economically  operated as a single  interconnected and coordinated system and no
adverse finding is required on  anticompetitive  grounds under Section 10(b)(1).
As demonstrated  below,  the size of the combined system will not have a adverse
effect upon localized  management,  efficient operation or effective  regulation
and the Merger will result in economies and efficiencies under Section 10(c)(2).

     Finally,  Applicants  retained  the Pacific  Economics  Group to  determine
whether the service  territories of NSP and NCE constitute a single region under
traditional economic theories.  The report of the Pacific Economies Group, filed
as EXHIBIT K-1,  demonstrates  that the companies  operate in a single,  unified
economic region.  Pacific  Economics Group used a gravity model to demonstrate a
high  degree of  economic  interaction  in the  region  including  NSP and NCE's
service  territories.   Finally,   Pacific  Economics  further  found  that  the
geographic  Elzinga-Hogarty  market analysis  underscores  this result,  clearly
identifying that the companies  operate within a distinct  economic region.  For
all of these reasons,  the Applicants believe that the Xcel Electric System will
be confined to a single area or region, within the meaning of the Act./99

----------
99   As explained  below,  the Xcel Gas System,  which spans the same geographic
     expanse,  is itself an integrated public utility system which by definition
     is confined "to a single area or region."

----------

                         (d)     Size

     The final clause of Section 2(a)(29)(A)  requires the Commission to look to
the size of the combined system  (considering  the state of the art and the area
or  region  affected)  and  its  effect  upon  localized  management,  efficient
operation and the  effectiveness  of regulation.  In the instant  matter,  these
standards are easily met. The size of the Xcel  Electric  System will not impair
the advantages of localized management, efficient operation or the effectiveness
of  regulation.  Instead,  the Merger will actually  increase the  efficiency of
operations.

     Localized  Management -- The Commission has found that an acquisition  does
not  impair  the  advantages  of  localized  management  where  the new  holding
company's "management [would be] drawn from the present management"  (Centerior,
supra), or where the acquired  company's  management would remain  substantially
intact (AEP,  supra).  The  Commission  has noted that the distance of corporate
headquarters  from local  management was a "less important factor in determining
what is in the public interest" given the "present-day ease of communication and
transportation."  AEP, supra. The Commission also evaluates localized management
in terms of whether a merged  system will be  "responsive  to local needs." AEP,
supra.

     The management of Xcel will be drawn primarily from the existing management
of NSP and NCE and  their  subsidiaries.  NSP  will  continue  to  maintain  its
corporate headquarters in Minneapolis and will maintain the management structure
of its combined subsidiary companies (including the electric operating and other
subsidiary   companies  of  NCE)  essentially   intact.   The  electric  utility
subsidiaries  will continue to operate  through the regional  offices with local
service  personnel and line crews available to respond to customers needs.  Xcel
will  preserve  the  well-established  delegations  of authority -- currently in
place at NSP and NCE -- which permit the local, district and regional management
teams to budget for, operate and maintain the electric  distribution  system, to
procure  materials and supplies and to schedule work forces in order to continue
to provide the high quality of service  which the  customers of NSP and NCE have
enjoyed in the past. In short,  the management  structures of NSP and NCE, which
are responsive to local needs, will be left essentially intact after the Merger.
Accordingly, the advantages of localized management will not be impaired.

     Efficient  Operation  -- As  discussed  above in the  analysis  of  Section
10(b)(1),  the size of Xcel will not impede  efficient  operation;  rather,  the
Merger will result in  significant  economies and  efficiencies  as described in
Item 3.C.2 below.  Operations  (as described in Item 1.E.) are more  efficiently
performed on a  centralized  basis  because of economies of scale,  standardized
operating and  maintenance  practices  and closer  coordination  of  system-wide
matters.

     Effective  Regulation  -- The Merger will not impair the  effectiveness  of
regulation at either the state or federal level. The utility subsidiaries of NCE
will  continue to be regulated  by the state  commissions  of  Colorado,  Texas,
Wyoming,  Oklahoma,  New Mexico and Kansas with respect to retail rates, service
and related matters.  The electric utility  subsidiaries of NSP will continue to
be regulated by the state commissions of Minnesota,  North Dakota, South Dakota,
Michigan  and  Wisconsin  with  respect to retail  rates,  service  and  related
matters./100 On the federal level,  Xcel will be fully regulated as a registered
holding company.  The electric utility  subsidiaries of Xcel will continue to be
regulated  by FERC  with  respect  to  interstate  electric  sales  for  resale,
transmission  services  and  other  matters,  by the  NRC  with  respect  to the
operation  of  nuclear  facilities,  and by the  FCC  with  respect  to  certain
communications  licenses.  The  jurisdiction  of  other  federal  regulators  is
similarly not affected.

     Moreover,  the  Merger  Agreement  requires  approvals  from  most  of  the
regulatory  authorities having jurisdiction over the Xcel Operating Companies as
a condition to the  consummation  of the Merger.  Applicants are working closely
with such regulators  (both state and federal) to obtain the required  approvals
(as  described  below  in Item  4).  Presumably,  if the  Merger  results  in an
impairment  of  regulatory  authority,  the state  commissions  will not approve
it./101

----------
100  The  NSP  and  NCE   management   structures  are  designed  to  facilitate
     communications  with state  regulators.  Each company has established State
     offices  which  have  responsibility  for  regulatory,  environmental,  and
     corporate  communications and have other external relations purposes. These
     state  offices  provide a single  point of  contact  with each of the state
     regulatory  and  environmental  offices  and  have the  responsibility  for
     handling all regulatory  contacts,  including making regulatory filings and
     answering customer inquiries to the regulatory commissions.  It is expected
     that these offices will be left essentially intact after the Merger.

101  In fact, a key aspect of the merger  applications is to explain why no such
     impairment of regulatory authority occurs.

----------

     Also, the FERC Merger Order addressed the potential impact of the Merger on
regulation. The FERC stated:

     As explained in the Policy Statement, the Commission's primary concern with
     the effect on regulation of a proposed merger involves  possible changes in
     the Commission's  jurisdiction when a registered holding company is formed,
     thus invoking the  jurisdiction  of the Securities and Exchange  Commission
     (SEC).  We are also concerned with the effect on state  regulation  where a
     state does not have the  authority to act on a merger.  . . With respect to
     state regulation,  Applicants note that the transaction will be reviewed by
     the state public utility commissions of Minnesota,  North Dakota,  Arizona,
     New Mexico,  Colorado,  Wyoming and Texas and will not impair regulation in
     any of these  state  jurisdictions.  In  addition,  Applicants  state  that
     although the public  utility  commissions of Kansas,  Wisconsin,  Michigan,
     Oklahoma,  and South  Dakota do not have  direct  authority  to approve the
     merger  transaction,  each state commission has authority to protect retail
     customers  from the effects of the merger.  Applicants  maintain that their
     operating  companies will continue to be subject to state  regulation after
     the transaction in each of these jurisdictions.  Intervenors, including the
     public utility commissions of the states of Wisconsin,  South Dakota, North
     Dakota, and Minnesota, raise no issues of adverse impact on regulation.

     Accordingly,  in light of the facts and  commitments  stated above,  we are
     satisfied  that the  proposed  merger  will not have an  adverse  effect on
     regulation./102

     Summary

     The cumulative effect of the regulatory, technological and economic changes
discussed above have significantly changed what is now the "state of the art" in
the  electric   industry.   The   Commission   must  respond  to  these  changes
realistically  in a manner that furthers the national and local energy  policies
that have developed.

     A rigid reading of the integration  requirement was undoubtedly appropriate
at a time when  ownership or control of the  intervening  lines was the only way
that a utility could move power from its generation  assets to its  distribution
systems.  The need  for  this  type of firm  physical  interconnection  has been
reduced, if not eliminated,  as the distribution  systems now routinely contract
for  power  with  nonaffiliates  and move the  purchased  commodity  power  over
independently   operated  or  owned  transmission  lines  --  or  eliminate  the
requirement  for  physical  movement of power from the  generator to the utility
system  through  use of  market  swaps,  power  displacement  or  other  similar
techniques.  Indeed,  a narrow reading of the  integration  standard could force
merging   parties   to   a   "Hobson's   choice,"   by   requiring   unnecessary
interconnections  that could cause a merger to fail to satisfy FERC's  standards
for approval.

     In the 1995 Report,  the Division  recommended that the Commission focus on
whether the resulting system will be subject to effective regulation.  The Study
emphasized that "open access under FERC Order No. 636,  wholesale wheeling under
the  Energy  Policy  Act [and FERC  Order  No.  888] and the  development  of an
increasingly  competitive  and  interconnected  market for wholesale  power have
expanded the means for achieving the  interconnection and the economic operation
and  coordination of utilities with  non-contiguous  service  territories."  The
Study further expressed concern that the Act "not serve as an artificial barrier
where other energy  regulators have determined that an acquisition  will benefit
utility  consumers."  Accordingly,  the Study concluded that "[w]hen considering
any proposed  acquisition,  the SEC should consider whether the resulting system
will impair the effectiveness of regulation.  Where the affected state and local
regulators concur, the SEC should interpret the integration standard flexibly to
permit  non-traditional  systems if the standards of the Act are otherwise met."
(Emphasis added.) Under this approach, if the affected States approve a proposed
transaction (a condition precedent to the instant Merger), the "effectiveness of
regulation" standard would be met.

     In  summary,  the  Applicants  believe  that the Merger  will  result in an
integrated  electric system under the current "state of the art" in the electric
industry. The NCE and NSP systems will be physically interconnected through both
the 100 Mw Northbound Path and common  membership in MISO.  Either is sufficient
to  meet  the  physically  interconnected  standard.  The  two  systems  will be
economically   operated  as  a  single  interconnected  and  coordinated  system
primarily through the Joint Operating  Agreement and New Century  Services.  The
two  systems  will be in the same area or region.  Finally,  the Merger will not
impair localized management,  efficient operation or effective  regulation.  The
Merger also will benefit  investors,  consumers and the public interest and will
not give rise to the evils against which the Act is addressed.  Accordingly, for
the reasons set forth above,  the Commission  should find that the Xcel Electric
System comprises a single, integrated electric-utility system within the meaning
of the Act.

          (ii)    Retention of Combined Gas System

     Because the Commission has interpreted the term "integrated  public-utility
system" to mean a system  that is either gas or  electric,  but not both,  it is
necessary to qualify the combined gas  operations  of NSP and NCE (the "Xcel Gas
System") under the "A-B-C" clauses of Section 11(b)(1).  Under those provisions,
a registered holding company can own "one or more" additional integrated systems
if certain conditions are met.  Specifically,  the Commission must find that (A)
the additional  system "cannot be operated as an independent  system without the
loss of substantial  economies  which can be secured by the retention of control
by such holding company of such system," (B) the additional system is located in
one state or adjoining  states,  and (C) the  combination  of systems  under the
control  of a single  holding  company  is not so large . . . as to  impair  the
advantages of localized management, efficient operation, or the effectiveness of
regulation."

     As shown below,  the Xcel Gas System will  constitute a single,  integrated
public utility system. Section 2(a)(29)(B) defines an "integrated public utility
system" as applied to gas utility companies as:

     a system  consisting  of one or more gas  utility  companies  which  are so
     located and related that substantial  economies may be effectuated by being
     operated as a single  coordinated  system  confined in its  operation  to a
     single  area or region,  in one or more  States,  not so large as to impair
     (considering  the  state of the art and the area or  region  affected)  the
     advantages  of  localized   management,   efficient   operation,   and  the
     effectiveness of regulation:  Provided, that gas utility companies deriving
     natural gas from a common  source of supply may be deemed to be included in
     a single area or region.

The combined gas operations of NSP and NCE satisfy this definition.

     First, both the Commission's precedent and current technological  realities
indicate that the Xcel Gas System will operate as a coordinated  system confined
in its operation to a single area or region  because it will derive  natural gas
from common  sources of supply,  and utilize common  transportation  and storage
facilities.  The gas utility  operations of NSP and NCE will operate in a single
area or region,  as those  operations  are in the adjoining  states of Michigan,
Wisconsin, Minnesota, North Dakota, South Dakota, Wyoming, Colorado and Arizona.
The Commission has not traditionally required that the pipeline facilities of an
integrated  gas  system be  physically  interconnected.  See,  Penzoil  Company,
Holding Co. Act Release No.  15963 (Feb.  7, 1968)  (finding an  integrated  gas
utility  system where some gas utility  properties  were not connected  with the
rest of the system,  but with the  facilities  of an  unaffiliated  transmission
company  from which the system  purchased  all  natural  gas  supplied  to those
properties, but not each other). See also, American Natural Gas Company, Holding
Co. Act Release No. 15620 n.5 (Dec.  12, 1966) ("It is clear the  integrated  or
coordinated operations of a gas system under the Act may exist in the absence of
such  interconnection").  Instead,  the  Commission has looked to such issues as
from whom the distribution  companies  within the system receive much,  although
not all, of their gas supply. See, e.g., Philadelphia Company and Standard Power
and Light Company, Holding Co. Act Release No. 8242 (June 1, 1948) ("most of the
gas used by these companies in their  operations is obtained from common sources
of supply"); Consolidated Natural Gas Company, Holding Co. Act Release No. 25040
(Feb. 14, 1990) (finding  integrated  system where each company  derived natural
gas from two transmission companies, although one such company also received gas
from other sources);  Sempra Energy,  Holding Co. Act Release No. 26971 (Feb. 1,
1999)  (finding  an  integrated  system  where  each  utility  would  derive  "a
significant  amount"  of gas  from two  basins  and  noting  that gas can now be
obtained by more flexible and efficient  means, due to the development of market
centers,  hubs and pooling points). The Commission also has considered obtaining
gas from a common  pipeline,  North  American  Company,  Public  Holding Co. Act
Release No. 11530 (finding  Panhandle  Eastern pipeline to be a common source of
supply):  NIPSCO  Industries,  Holding Co. Act Release No. 26975 (Feb. 10, 1999)
(finding an integrated  system where the applicants  had contracted  capacity on
only one common  long-haul  pipeline  and ten of sixteen  individual  interstate
pipelines on which the applicants' systems had contract capacity  intersected at
and  formed  industry-recognized  trading  hubs),  as  well  as  from  different
pipelines  when the gas  originates  from the same gas  field in  determining  a
common source of supply.  See,  Central Power  Company and  Northwestern  Public
Service  Company,  Holding Co. Act Release No. 2471 (Jan. 6, 1941), in which the
Commission  declared an integrated  system to exist where two entities  purchase
from  different  pipeline  companies  since "both  pipelines run out of the Otis
field,  side  by  side,  and are  interconnected  at  various  points  in  their
transmission  system;  and  that  they are  within  two  miles of each  other at
Kearney." See also,  MCN  Corporation,  Holding Co. Act Release No. 26576 (Sept.
17, 1996)  (finding an  integrated  system where one gas utility  would  receive
70-90% of its gas supply from the same basin from which two affiliates  received
46% and 55% of their  supply).  Since the time of most of these  decisions,  the
state of the art in the industry has developed to allow  efficient  operation of
systems whose gas supplies derive from many sources.

     The NSP and NCE gas operations  today purchase gas from multiple basins and
transport gas on multiple  pipelines in order to enhance supply  competition and
provide  increased  reliability.  However,  NSP  and  NCE  purchase  significant
quantities  of natural gas from common  supply  basins as shown below.  As shown
below,  approximately  75% of the  324.7 Bcf of  natural  gas  purchased  by the
combined  NSP/NCE gas  operations  during 1998 were from common  supply  sources
(i.e., the MidContinent,  Permian and Rocky Mountain basins),  with NCE deriving
more than 92% of its gas supplies and NSP deriving  approximately 36% of its gas
supplies from such common sources. The majority of these supplies were delivered
off of the  Northern  Natural Gas Company  ("NNG") and Colorado  Interstate  Gas
Company  ("CIG")  pipeline  systems to NSP and NCE,  respectively.  The pipeline
systems  of NNG and CIG  are  directly  connected  in two  locations  in the Mid
Continent supply basin (i.e., the Hugoton and Anadarko supply basins).  Together
NCE and NSP hold over 1.5 Bcf of daily  capacity and receive peak day deliveries
in excess of 1.7 Bcf from the NNG and CIG pipeline systems. NSP and NCE purchase
gas from the following major supply basins:


 NATURAL GAS         NCE                            NSP
 FIELD/BASIN        (Bcf)          NCE %           (Bcf)           NSP %

Alberta               -             -              41.9             43.2
Other                 -             -              20.4             21.0
                    -----         -----            ----            -----
Total               227.6         100.0            97.0            100.0

     In  addition  to the  above,  NCE  and  NSP  own  or  have  contracted  for
significant  underground gas storage and own local gas peak shaving  capacity at
numerous locations  throughout Colorado,  Minnesota,  Texas and other Midwestern
states.  The vast majority of this storage and peak shaving capacity is directly
linked or accessible  to the NNG and CIG pipeline  systems.  As a result,  these
operationally  flexible assets have the ability to further  integrate the common
sources of supply for NCE and NSP. Access to the various storage  facilities and
pipelines  forms a grid  upon  which the  companies  can  source  supply to take
advantage of relative shifts in market  conditions  among the various  producing
basins.

     The concept of a "common  source of supply" is  susceptible  to a different
understanding today than in 1935, when the "single area or region" was generally
defined in terms of the pipeline  delivery points (i.e.,  the city gate),  where
system LDCs  purchased  their gas.  Sempra  Energy,  Holding Co. Act Release No.
26971 (Feb. 1, 1999). In Sempra,  the Commission  recognized  "that the relevant
inquiry today is whether the system LDCs purchase substantial  quantities of gas
produced in the same supply basins,  and whether that gas is  'deliverable' - in
other words,  whether there is sufficient  transportation  capacity available in
the  marketplace to assure  delivery on an economical  and reliable  basis." See
also NIPSCO  Industries,  Inc.,  Holding Co. Act Release No. 26975 (February 10,
1999) (NIPSCO  Industries'  acquisition of Bay State Gas Company,  in which case
the Commission  held that  "[a]lthough  the  intervening  territory  between the
NIPSCO Operating  Companies is significant,  we do not believe that the distance
contravenes  the policy of the Act  against  scatteration  -- the  ownership  of
widely  dispersed  utility  properties which do not lend themselves to efficient
operation and effective state regulation").

     In NIPSCO Industries'  acquisition of Bay State Gas Company, the Commission
recognized  that the "state of the art" in the gas industry  continues to evolve
and  change,  primarily  as a  result  of  decontrol  of  wellhead  prices,  the
continuing development of an integrated national gas transportation network, the
emergence of marketers and brokers,  and the  "unbundling"  of the commodity and
transportation functions of the interstate pipelines in response to various FERC
initiatives, in particular Order 636,/103 which has dramatically altered the way
in which local gas distribution  companies  purchase and ship their required gas
supplies. NIPSCO, supra.

----------
103  See 1995 Report, pp. 29-31.

----------

     The Commission has also  considered and recognized  that another  important
development  affecting  the "state of the art" in the natural gas  industry  has
been the creation of a national network of trading hubs and market centers.  The
development of trading hubs and market  centers was a natural  outgrowth of FERC
Order  436 and 636,  which,  as  indicated,  required  interstate  pipelines  to
separate,  or "unbundle," the commodity and transportation and storage functions
of the interstate pipelines.

     In this regard,  it is  significant  to note that,  6 of the 12  individual
interstate pipelines (long-haul and regional) on which the NCE and NSP companies
have contracted capacity intersect at and form industry recognized trading hubs.
These include:

     Trading hubs (including all of those listed above) essentially  function as
physical transfer points between intersecting  pipelines,  where shippers (i.e.,
buyers and  sellers)  and  traders  can sell,  exchange or trade gas or pipeline
capacity or redirect deliveries to a different pipeline.  Further, various types
of unbundled services are typically  available at trading hubs, such as parking,
loaning, and wheeling of gas and, in some instances, title transfer./104 Because
of the role played today by market hubs and market centers,  coordination of the
operations of two  non-contiguous  gas companies is no longer  dependent  solely
upon having contractual  capacity on the same interstate  pipelines,  so long as
the two companies both have access to one or more common trading hubs.

----------
104  "Parking"  is  essentially  a  short-term  interruptible  storage  service.
     "Loaning"  is a service by which a party with gas will  provide  the gas to
     another  party  with a  specific  date for the return of such gas at either
     that  location  or another  location  under  mutually  agreeable  terms and
     conditions (in effect, the inverse of parking). "Wheeling" is the provision
     of  transportation  by a hub  operator  from one system to another  system.
     Finally,  "title transfer"  services allow parties to exchange title to gas
     that is already within a pipeline system for gas at different points on the
     same pipeline system or for gas that is on another pipeline system, without
     the requirement of physical  movement.  Title transfer in itself allows the
     shippers to minimize transportation costs.

----------

     Importantly, trading hubs now allow gas distribution companies operating in
a much larger area or region of the country to realize  operating  economies and
efficiencies from coordinated operations that were once thought to be achievable
only by  contiguous  or nearly  contiguous  gas  companies  supplied by the same
interstate pipelines.  In fact, as discussed below, the opportunities to achieve
operating  economies  may be even  greater  where the two  companies  seeking to
combine  have  significantly  different  load  profiles  (e.g.,   non-coincident
seasonal  peaks, a substantially  different  customer mix, etc.) or where, as in
this case,  the two  companies  are  located in two  different  major gas market
centers,  experience  non-coincident peak demands,  and are served (to a degree)
from common supply basins.

     Because  NSP  and  NCE  share  access  through  their  respective  pipeline
transporters to several  industry-recognized  market and supply-area  hubs, they
will have the ability to physically  coordinate  and manage their  portfolios of
gas supply, transportation, storage and peak shaving. Each of the hubs or market
centers is served by a significant  number of competing  pipeline  transporters,
further  expanding the potential supply options available to the merged company.
In addition, as customers of hub services,  NSP and NCE are among an even larger
number of other customers of such services such as natural gas marketers,  local
distribution companies, and other wholesale customers.

     For example, the ANR and NNG pipelines, which transport gas to NSP, and the
KN and Williams  pipelines,  which  transport  gas to NCE, all  intersect at the
MidContinent   Market  Center  hub  located  at  Greensburg,   Kansas.   At  the
MidContinent  Market Center hub, NSP can arrange and consummate  direct physical
purchases and trades of gas and/or transportation  capacity with NCE or with any
other shipper having access to the  MidContinent  Market Center hub. NSP and NCE
also have access to the Waha Permian Basin hub near Odessa, Texas via contracted
capacity  on the NNG and El Paso  pipelines.  The Waha  Permian  Basin  hub is a
recognized  center for western  natural gas index price  futures  trading in the
U.S.  Through four  interstate  and six  intrastate  pipeline  interconnections,
market participants such as NSP and NCE can physically support, if necessary and
if  permitted  by  state  regulatory   bodies,   the  utilization  of  financial
derivatives as a means of managing price volatility.

     Moreover,  through its contracted capacity on the CIG and KN pipelines, NCE
would  have  access to the  storage  capacity  held by NSP on NNG and ANR.  Such
access will enhance Xcel's ability to manage price volatility.  These facilities
would also provide NSP and NCE with an important gas balancing capability, which
will allow them to manage  fluctuating  weather-related  load  profiles  of each
other's system.

     Finally,  NSP and NCE would have direct access to the Chicago market center
hub, which is expected to become an increasingly important source of gas for all
eastern U.S. markets.

     In the current natural gas industry,  limitations on the  deliverability of
gas in most areas of the country have  disappeared.  Under Section  2(a)(29)(B),
these "state of the art"  changes in the  industry are directly  relevant to the
issue of the  appropriate  size of the "area or region" in which an "integrated"
gas system may operate.

          (iii)  Coordinated Operations of Combined Gas Properties

     NSP and NCE currently  manage similar  physical  properties and contractual
assets (gas supply,  pipeline  transportation,  and storage contracts of varying
types and duration).  Each company maintains a professional  staff that performs
essential portfolio management functions.

     After the Merger,  the gas supply  departments  of NSP and  NCE,/105  which
provide  both  gas  supply  planning  and  gas  acquisition  services,  will  be
consolidated  and  become  part  of NCE  Services.  NCE  Services  will  provide
financial,   accounting,  tax,  purchasing,  and  other  services  to  associate
companies,  including,  gas supply planning and gas acquisition  services to the
gas utility operations of the Xcel system.

     The  gas  supply  planning  function  will  perform  portfolio  design  and
strategy./106  The gas  acquisition  function  will  implement  this strategy on
behalf  of the  Xcel gas  operating  companies  through  scheduling  and  supply
procurement,/107  storage   optimization,/108  price  risk  management,/109  and
contract  adminstration./110  As explained  below,  NCE and NSP have  identified
specific  components of their gas  management  strategies  which,  through joint
management  and  coordination,  will enable the  combined  companies  to enhance
opportunities for savings in the marketplace.

----------
105  The gas supply department of NSP currently  consists of 9 individuals.  NCE
     gas supply department consists of eight individuals.

106  Portfolio  design includes the development of demand forecasts and modeling
     of the appropriate  combination of portfolio  components (e.g., the optimum
     levels of "firm"  transportation  and long-term gas  purchases,  short-term
     transportation and supply, and sportmarket  transactions) to meet projected
     demand and the  negotiation of all  transportation  and storage  contracts.
     Portfolio  strategy  involves the development of strategies to optimize the
     daily and seasonal  utilization of portfolio assets through the correlation
     of supply area and market area pricing activity with the load  requirements
     and pressures of each individual company.

107  Procurement  involves  daily and  short-term  (less than three  months) gas
     purchases  in supply  basis,  market  centers,  pooling  points,  and other
     markets, based on the plan developed by the portfolio strategy group.

108  Storage,  optimization involves maximizing the "value" of storage contracts
     and storage that is owned through  coordination and management of injection
     and withdrawal volumes and rates.

109  Price  risk  management  implements  strategies,  using both  physical  and
     financial contracts, within guidelines approved by the board of directors.

110  Contract  administration  is responsible  for contract  administration  and
     accounting  functions,  scheduling/nomination  of gas shipments,  and state
     regulatory reporting and support functions.

----------

     The two gas  supply  planning  departments  will be  unified  under  common
management  and,  through use of common software  (known as  SENDOUT(TM)),  will
provide a consistent  approach for planning  and  designing  supply  portfolios,
including upstream resources of transportation and storage.  The gas acquisition
function will also be under common  management  and it is planned that the group
will  utilize  a  common  software  program  for the gas  acquisition  functions
described above.

     The gas  departments  of NSP  (except  for BMG) and NCE will also be linked
upon consolidating their Gas Supervisory Control and Data Acquisition  ("SCADA")
systems. This system electronically  communicates gas flow and gas pressure, and
gas equipment set point data thereby  monitoring the adequacy and reliability of
gas supplies being delivered at the individual-town  border stations serving NSP
or NCE retail  distribution  systems.  Consolidated SCADA operations (which will
take some time to implement to assure gas reliability) will promote efficiencies
and coordination among the NCE and NSP gas systems.

     Through the coordination and use of supply/demand information,  NSP and NCE
will be able to maximize  revenues and minimize  costs in such areas as pipeline
capacity and storage utilization following the Merger.  Several illustrations of
how the merger of the gas departments  will result in coordination of gas supply
to the NCE and NSP systems were discussed above and include:

     -    Using the data gathered and analyzed by the common  management and the
          planned  software  tools,  NCE  Services  will be able to make  supply
          acquisition  decisions that lower overall gas costs. With knowledge of
          available storage capacity at any moment,  and weather  conditions and
          other factors affecting  anticipated demand, NCE Services will be able
          to make coordinated decisions for both systems, buying or selling firm
          capacity or, as explained  above,  diverting gas from the company with
          excess supply to the company in need of such supply.

     -    At the  MidContinent  Market  Center hub, NCE Services can arrange and
          consummate  direct  physical   purchases  and  trades  of  gas  and/or
          transportation  capacity  with  NCE or NSP or with any  other  shipper
          having  access  to the  MidContinent  Market  Center  hub  as two  key
          pipelines  serving  the  companies  (Northern  Natural  and KN Energy)
          intersect there.

     -    New NSP will  increase  the  maximum  daily  production  at one of its
          peak-shaving  facilities  by  approximately  40%. NSP has already made
          significant   investment  on  this  project  in  anticipation  of  the
          completion  of the Merger.  When system  demand  conditions on the NCE
          system  require,  NSP would  increase the output of this  facility and
          serve NSP loads with peak shaving gas, and deliver NSP pipeline gas to
          the NCE system.  This arrangement  would reduce  consolidated  reserve
          margin needs while preserving  reliability.  In addition, on days when
          the peak shaving capacity is needed by NSP customers, New NSP would be
          able to increase  the output of the  facility to serve the firm supply
          needs of NSP gas customers. (This is quite similar to the coordination
          provided by the 100 MW contract  path between SPS and NSP as that path
          will allow energy produced by SPS to be transferred to NSP just as the
          peak-shaving  expansion  creates  a  similar  transfer  of New NSP gas
          supply to NCE on days when it is most needed by NCE).

     Other  aspects  of  coordinated   operations  will  be  common  performance
measurements and strategies to meet performance targets that will be implemented
by the Xcel gas distribution companies.  This coordinated management through NCE
Services,  with operational  implementation  through localized management,  will
assure the gas distribution companies are well maintained and managed throughout
the NSP/NCE system.

     As indicated in Item 3.C.2 below,  combination and  coordination of the NCE
and NSP gas  operations  will result in significant  economies and savings.  The
estimated  dollar value of synergies from the combination of the two gas systems
is expected to exceed $100 million over the 10-year  period from  2001-2010,  of
which $77.4 is  expected to be derived  from  natural  gas supply  savings.  The
natural gas supply savings are based in large part on the coordinated activities
discussed above,  including gas transport and storage capacity  reductions,  gas
reserve margin reductions,  field transportation reductions and capacity release
savings.

     Finally, as discussed below in detail in Item  3.c.1.(b).(iii).(c).  in the
context of Section 11(b)(1)(c) of the Act, the system will not be so large as to
impair  the  advantages  of  localized   management  or  the   effectiveness  of
regulation.  Localized  management  will be  preserved.  It is expected that the
centralized  functions of the Xcel gas system will be managed from one location,
and the local  functions  will  continue  to be handled  from  several  regional
offices.  Management  will,  accordingly,  remain  close to the gas  operations,
thereby  preserving the advantages of local  management.  And, from a regulatory
standpoint,  there will be no impairment of regulatory  effectiveness.  The same
state regulators currently overseeing these gas operations will continue to have
jurisdiction  after the  proposed  transaction  is  completed.  Those same state
regulators  are  already  regulating  multi-jurisdictional  gas  or  combination
gas/electric utilities.

     For all of these  reasons,  we believe  that the Xcel gas  operations  will
satisfy the integration requirements of Section 2(a)(29)(B).

                    (a)  Loss of economies

     Historically,  the  Commission  had  considered  the  question of whether a
registered  electric  system  could  retain a separate gas system under a strict
standard that required showing a loss of substantial  economies before retention
would be permitted.  New England Electric System,  41 S.E.C. 888 (1964).  In its
affirmation  of that  decision,  the U.S.  Supreme Court declared that a loss of
substantial economies could be demonstrated by the inability of the separate gas
system to survive on a stand-alone  basis.  SEC v. New England  Electric System,
384 U.S.  176, 181 (1966).  This rigid  interpretation  of the  requirements  of
Section  11(b)(1) has been explicitly eased by the Commission in its most recent
decisions  under  Sections  9(a) and 10 of the Act both with  respect  to exempt
holding companies (TUC Holding Company,  Holding Co. Act Release No. 26749 (Aug.
1, 1997) and Houston Industries Incorporated,  Holding Co. Act Release No. 26744
(July 24,  1997)) and newly  formed  registered  companies  (e.g.,  SCANA Corp.,
Holding Co. Act Release No. 27133 (Feb. 9, 2000); 1997 NCE Order).

     In these recent decisions,  the Commission acknowledged that as a result of
the  transformation of utilities'  status as franchised  monopolies with captive
ratepayers  to  competitors  and  also as a  result  of the  convergence  of the
electric and gas industries that was then underway (and which continues  today),
the  historical  standards  of review had  become  outdated  and that  separated
electric  and gas  companies  might be weaker  competitors  than  they  would be
together  in the same  market.  SCANA  Corp.,  supra.;  1997 NCE Order;  Houston
Industries  Incorporated,  Holding Co. Act Release  No.  26744 (July 24,  1997).
Thus, newer  transactions such as the Merger should be evaluated on the basis of
new Commission precedent and policy in light of changing industry standards.

     Applicants  believe that the  Commission  should allow the retention of the
NSP-NCE  gas  operations  as a matter  of  policy  and as a matter  of law.  The
Commission  already has  acknowledged  that the electric and gas  industries are
converging and that combination companies may be more effective competitors in a
given market.  This trend towards,  and the need for,  convergence of the former
separate  electric  utility  function and gas utility  function  into one energy
service  company was  recently  recognized  by the  Commission  in  Consolidated
Natural  Gas  Company,  Holding  Co. Act  Release  No.  26512  (April 30,  1996)
(hereinafter,  the "CNG Order"),  where the Commission  stated: "It appears that
the restructuring of the electric industry now underway will dramatically affect
all United States energy markets as a result of the growing  interdependence  of
natural gas transmission and electric generation,  and the interchangeability of
different forms of energy,  particularly gas and  electricity."  See also UNITIL
Corp.,  Holding Co. Act Release No. 26527 (May 31, 1996);  SEI  Holdings,  Inc.,
Holding Co. Act Release No.  26581 (Sept.  26,  1996);  and Dominion  Resources,
Inc.,  Holding  Co. Act  Release  No.  27113  (Dec.  15,  1999).  In the instant
situation,  the lost  economies  that would follow from denying the retention of
the  NSP-NCE  gas   operations  are   substantial,   both   quantitatively   and
qualitatively.

     Divestiture  of the NSP and NCE gas  properties  either into one company or
into separate companies would result in the loss to consumers of the cost-saving
benefits of the economies offered by the "energy  services"  approach of NSP and
NCE to the utility  business.  While the losses cannot now be fully  quantified,
they are  substantial.  At the center of the energy services  company concept is
the idea that providing gas and electric services and products is only the start
of the utility's job. In addition,  the utility must provide enhanced service to
the  consumer  by  providing  an entire  package  of both  energy  products  and
services. In this area, NSP's and NCE's efforts are part of a trend by utilities
to organize  themselves as energy service companies;  that is, as providers of a
total  package  of energy  services  rather  than  merely  suppliers  of gas and
electric  products.  The goal of an energy  service  company  is to  retain  its
current  customers  and  obtain new  customers  in an  increasingly  competitive
environment by meeting  customers' needs better than the competition.  An energy
service  company can provide the  customer  with a low cost energy  (i.e.,  gas,
electricity or conservation) option without inefficient subsidies.

     As the Commission  recognized in SCANA, WPL Holdings,  TUC Holdings and the
1997 NCE Order,  there are  significant  economies  and  competitive  advantages
inherent  in a combined  gas and  electric  utility as  contrasted  to a utility
offering only electricity or gas. Besides the loss of these inherent  economies,
other  substantial  economies  would be lost by the  separation  of the electric
systems from the gas  systems.  These lost  economies  would  include  decreased
efficiencies from separate meter reading,  meter testing and billing operations,
as well as decreased  efficiencies in customer  service  operations,  savings in
facilities maintenance and emergency work coordination, and other administrative
operations. As a result, the stand alone gas company (or separate gas companies)
would have greater operating costs per unit sold and would, therefore, realize a
lesser   amount  of  any   increased   revenue  on  its  bottom  line.  A  final
consideration,  also raised by the Commission in the 1997 NCE Order, is that the
gas and electric  properties of NCE and NSP have long been under common control,
and  approval of the Merger will not alter the status quo with  respect to these
operations.

     While the  Applicants  believe that the  foregoing is  sufficient to permit
retention under the standard established in SCANA,  supra.,  Applicants also can
demonstrate loss of economies under a more traditional  analysis.  Historically,
the  Commission  has given  consideration  to four  ratios,  which  measure  the
projected  loss of  economies as a percentage  of: (1) total  utility  operating
revenues; (2) total utility expense or "operating revenue deductions"; (3) gross
utility income;  and (4) net utility operating  income.  Although the Commission
has declined to draw a bright-line numerical test under Section 11(b)(1)(A),  it
has  indicated  that  cost  increases  resulting  in a 6.78%  loss of  operating
revenues,  a 9.72% increase in operating  revenue  deductions,  a 25.44% loss of
gross gas income and a 42.46%  loss of net income  would  afford an  "impressive
basis for finding a loss of  substantial  economies."  Engineers  Public Service
Co., Holding Co. Act Release No. 1632 (Sept. 16, 1942).

     Direct Loss of Economies.  NSP and NCE have each prepared  separate studies
of their respective gas utility  operations that analyze the lost economies that
their gas utility  operations  would suffer upon  divestiture  when  compared to
their  retention  pursuant to the  Merger.  These  studies are  attached to this
Application as Exhibit J-1 and Exhibit J-2/111 (the "Gas Studies"). As set forth
in the Gas  Studies,  if the gas  operations  of NSP and NCE were  operated on a
stand-alone basis, lost economies from the need to replicate services,  the loss
of economies of scale, the costs of  reorganization,  and other factors would be
immediate and substantial.  In the absence of rate relief,  those lost economies
would substantially  injure the shareholders of NSP and NCE upon the divestiture
of those gas  operations.  As the  studies  further  show,  if rate  relief were
granted  with respect to the lost  economies,  then  consumers  would bear those
substantial  costs  over  what they  would  have to pay if the  properties  were
retained as contemplated by the Merger.

----------
111  As described  below,  the Applicants have also jointly prepared an analysis
     of the effects of combining  their gas properties into one company prior to
     divestiture, which is filed as Exhibit J-3.

----------

     As set forth in the Gas Studies, divestiture of the gas operations of PSCo,
Cheyenne,  NSP  and  NSP-W  into  stand-alone  companies  would  result  in lost
economies of $25,807,000  for NSP,  $7,629,000 for NSP-W,  $55,862,000 for PSCo,
and  $1,417,000  for  Cheyenne.  The table  below  shows the 1998 gas  operating
revenues, gas operating revenue deductions,  gas gross income and gas net income
of NSP, NSP-W, PSCo and Cheyenne.


================================================================================
                        Gas             000s             Gas            Gas
                     Operating      Gas Operating       Gross           Net
        Company      Revenues    Revenue Deductions    Income         Income

NSP                  $360,567         $330,578         $29,989        $23,432
NSP-W                 $78,800          $73,510          $5,290         $3,691
PSCo                 $682,289         $585,557         $96,732        $73,321
Cheyenne              $20,995          $18,574          $2,421         $1,857
================================================================================


     On a percentage  basis, the lost economies amount to 76.19% of 1998 gas net
income  for PSCo,  76.35%  for  Cheyenne,  110.14% of gas net income for NSP and
206.69%  of gas net  income for NSP-W -- far in excess of the loss of net income
in UNITIL, where the Commission allowed the retention of gas utility operations,
and  the 30%  loss in New  England  Electric  System  that  the  Commission  has
described as the highest loss of net income in any past  divestiture  order./112
As a percentage of 1998 gas operating  revenues,  these lost economies described
in the Gas Studies amount to 8.19% for PSCo,  6.75% for Cheyenne,  7.16% for NSP
and 9.68% for  NSP-W--losses  substantially  higher  than the losses in any past
divestiture  order./113 As a percentage  of 1998  expenses or operating  revenue
deductions,  the lost  economies  described  in the Gas Studies  would amount to
9.54% for PSCo, 7.63% for Cheyenne,  7.81% for NSP, and 10.38% for NSP-W, higher
than the  losses in any past  divestiture  order and,  in  Entergy  Corporation,
Holding Co. Act Release No.  25952 (Dec.  17,  1993),  another case in which the
Commission  authorized the retention of gas operations.  As a percentage of 1998
gross income,  the lost economies  described in the Gas Studies amount to 57.75%
for PSCo,  58.53% for  Cheyenne,  86.05% for NSP and 144.22%  for NSP-W,  far in
excess of the highest loss of gross income in any divestiture order.

----------
112  See UNITIL Corp., supra ("The Commission has required  divestment where the
     anticipated  loss of income of the  stand-alone  company was  approximately
     30%..." or "29.9% of net income before  taxes"),  citing SEC v. New England
     Electric System, 390 U.S. 207, 214 n.11 (1968).

113  The highest loss of operating revenues in any case ordering  divestiture is
     commonly said to be 6.58%. See, e.g.,  UNITIL Corp.,  supra ("[o]f cases in
     which the Commission has required divestment, the highest estimated loss of
     operating revenues of a stand-alone company was 6.58%...").

----------

     In order to recover  these  estimated  lost  economies,  PSCo would need to
increase rate revenue by $57,738,000  or 8.53%,  Cheyenne would need to increase
revenue  by  $1,615,000  or  7.69%,  NSP  would  need to  increase  revenues  by
$26,723,000 or 7.41% and NSP-W would need to increase rate revenue by $7,812,000
or 9.91%.  These  increases in rate  revenues  would have a direct and immediate
negative impact on the rates charged to customers for gas services. In addition,
the  customers  of NCE and NSP gas  businesses  who are also  customers of their
respective  electric  utility  businesses  will  experience  a doubling of their
postage  costs to pay  separate  bills.  The total  estimated  increase  in such
postage  costs is $3.96 per customer  per year or  $6,026,733  in the  aggregate
($1,523,000 for NSP gas customers, $326,000 for NSP-W gas customers,  $4,065,000
for PSCo gas customers, and $113,000 for Cheyenne gas customers.)

     It is the intention of the Applicants that their separate gas properties be
integrated  and  operated  as a  single  economic  system  in  conjunction  with
Applicants' electric system in order to better provide competitive comprehensive
energy  services to Applicant's  customers.  Because today the properties of NSP
and NCE are operated as separate entities and Section  11(b)(1)(A),  (B) and (C)
appear to require  an  analysis  of "[e]ach  such  additional  system,"  the Gas
Studies  described  above looked at  divestiture  of four  separate gas systems,
preserving  their  present  status of being  separate  from one  another,  which
produced annual lost economies that are estimated to be $90.7 million per annum.

     The  Applicants  have also  prepared a study that  evaluates  the  economic
impact of a  divestiture  of the natural gas assets of NSP and NCE into a single
stand-alone   gas  holding  company   ("BigGasCo"),   Exhibit  J-3.  While  this
alternative  form of  divestiture  would allow some of the savings of the Merger
(primarily in natural gas supply procurement and  transportation  management) to
be realized,  the combination of the gas operations  under Xcel would facilitate
and enhance the  efficiency of the gas  operations to a much greater degree than
divestiture to a stand-alone  BigGasCo gas utility operation.  In addition,  the
increased  costs to the  remaining  Xcel  electric  utility  operations  are not
mitigated in any way,  thus reducing the  predicted  merger  savings to the Xcel
electric  utility  operations from the merger.  The lost savings to combined NSP
and NCE electric ratepayers would be $110,447,000 or 2.89%.

     As set forth in EXHIBIT J-3,  combining the Applicants' gas properties into
one  company  prior to  divestiture  would  still  result in lost  economies  of
$55,115,000,  assuming no rate  adjustments  to recover the lost  economies  and
associated  income taxes. On a percentage  basis,  this is equivalent to 4.8% of
total operating  revenue,  5.47% of total operating revenue  deductions,  41% of
gross income,  and 53.88% of 1998 net income.  These lost  economies are greater
(in three of the four measures)  than those found adequate to support  retention
in New England Electric System,  41 S.E.C. 888 (1964),  rev'd SEC v. New England
Electric System, 346 F.2d 399 (1st Cir. 1966), rev'd and remanded,  384 U.S. 176
(1965),  on remand,  376 F.2d 107 (1st Cir.  1967),  rev'd,  390 U.S. 2-7 (1968)
("NEES") (approving  retention on measures of 4.8% of operating revenues,  6% of
operating  revenue  deductions  (excluding  federal income tax),  23.3% of gross
income (before federal income taxes) and 29.9% of net income (before taxes). The
fact that the lost economies are below the levels in NEES for one measure is not
significant  because  the  Commission  has  established  that  retention  may be
warranted  when the "cost  increases that would result from severance of the gas
properties  would  in  most  instances  be  consistent  with  [the  established]
thresholds."  Dominion Resources,  Inc., Holding Co. Act Release No. 27133 (Dec.
15, 1999) (emphasis added) (citing NEES with approval).

     In the case of divestiture,  BigGasCo's  customers would pay $58,156,000 or
5.1% more in rates to offset these  losses.  In  comparison,  if the Merger were
implemented as proposed,  gas  ratepayers  would save  $20,736,000 or 1.82%.  In
addition,  both NSP's and NCE's gas  customers  would incur  increased  personal
costs, such as postage on a separate envelope and additional check costs to mail
payments to two utilities.  Finally, the earnings  contribution  relating to NSP
and NCE's combined gas businesses would be decreased by approximately  54%. Such
a  decline  would  make  ownership  of shares in this  stand-alone  gas  company
unattractive.

     In summary,  divestiture  of BigGasCo  would  result in a loss or necessary
rate increase of  $168,000,000  annually ($58 million in annual gas revenue plus
$110  million  in annual  revenue  increases  for the  remaining  Xcel  electric
companies).  These negative  consequences  do not tend toward the economical and
efficient development of an integrated public utility system.

     The lost  economies  occurring  from both  divestiture of NCE and NSP's gas
utilities  as  separate  businesses  and as a combined  stand-alone  company are
substantial in an industry in which there are already many  companies  competing
with  Applicants  for  the  provision  of   comprehensive   energy  services  in
Applicants'  service  territories and, where there is not yet competition,  lost
economies may well result in increased retail rates.  Competition between energy
suppliers  can  only  benefit  consumers.   Increasingly,  the  competitors  are
themselves  suppliers of  comprehensive  energy services just like NCE, NSP, TUC
Holding Company and Reliant Energy Inc.

     Accordingly,  it is  Applicants'  view that the  standards  of Clause A are
satisfied  in  light  of the  increased  expenses  and  the  potential  loss  of
competitive  advantages  that could result from  separation from the gas system.
Against this background,  Applicants believe that the Commission should find the
standards of Clause A satisfied  with respect to the gas systems of NCE, NSP and
NSP-W.

                    (b)  Same state or adjoining states

     The proposed  Merger does not raise any issue under Section  11(b)(1)(B) of
the Act.  The  Commission  has  paraphrased  Clause B as  follows:  "All of such
additional  systems are located in a state in which the single integrated public
utility system  operates,  or in states  adjoining such a state, or in a foreign
country contiguous  thereto." Engineers Public Service Company,  Holding Co. Act
Release No. 2897 (July 23,  1941),  rev'd on other  grounds,  138 F.2d 936 (D.C.
Cir. 1943), vacated as moot, 332 U.S. 788 (1947). The Xcel Gas System is located
in the same  states as the Xcel  Electric  System,  plus  Arizona,  and  Arizona
adjoins Colorado, a state in which the Xcel Electric System operates.  Thus, the
requirement  that each  additional  system is located in one state or  adjoining
states is satisfied.

                    (c)  Size

     Further,  retention  of the combined  gas  operations  of NCE and NSP as an
additional  integrated  system raises no issue under Section  11(b)(1)(c) of the
Act.  The  combination  of the  systems  under the  control of a single  holding
company will not be "not so large . . . as to impair the advantages of localized
management,  efficient  operation,  or the  effectiveness of regulation." As the
Commission has recognized elsewhere, the determinative consideration is not size
alone or size in an absolute sense, either big or small, but size in relation to
its effect, if any, on localized  management,  efficient operation and effective
regulation. From these perspectives,  it is clear that the continued combination
of the gas operations under Xcel is not too large.

     Even after the combination,  the gas utility  operations of New NSP, NSP-W,
BMG,  PSCo and Cheyenne,  with some 1.5 million gas customers  combined in seven
states,  will be smaller than Reliant Energy (the parent of  Minnegasco)  which,
through  subsidiaries,  has  2,700,000  gas  customers,  630,000 of which are in
Minnesota. This company is among NSP's and NCE's primary natural gas competitors
in the region. Based on data through December 31, 1998, and giving effect to the
Merger,  the combined gas assets will represent only 8.6% of the total assets of
Xcel,  whereas the electric assets will represent 51.6%;  operating revenues for
the gas operations will be 16.5% of total Xcel's revenues as compared with 74.1%
for the electric operations; and customers of the gas operations will constitute
33.3% of all Xcel's customers,  while electric  operations will represent 67.6%.
With respect to localized management,  this issue is discussed for the Merger as
a whole under Item 3.C.1.(b)(i)(a)  below. Applied solely to the gas operations,
the current NSP,  NSP-W,  BMG, PSCo and Cheyenne gas systems  enhance  localized
management  within the larger  corporate  structure  and will  continue to do so
after the Merger is completed.

     After the Merger, certain centralized gas functions of Xcel will be managed
by New Century  Services from a centralized  location,  and the local  functions
will  continue to be handled  from  regional  offices.  No reduction in customer
service  or  support  crews  is  expected.   Management  will  therefore  remain
geographically close to the gas operations, thereby preserving the advantages of
localized  management.  From the  standpoint  of regulatory  effectiveness,  NSP
already operates a combined gas and electric utility in Minnesota,  North Dakota
and South Dakota, as does NSP-W in Wisconsin and Michigan,  PSCo in Colorado and
Cheyenne in Wyoming.  In  addition,  several  other gas  utilities in the region
serve  customers in several states.  Thus, the regulatory  agencies in the seven
states are currently regulating  multi-jurisdictional  gas utilities and will be
able to  effectively  regulate  the gas  utility  operations  of Xcel  after the
Merger. In addition, the historical joint gas and electric utility operations of
NSP have never raised regulatory concerns in Minnesota and North Dakota, and NSP
has requested the Minnesota,  North Dakota and Arizona regulatory authorities to
make  findings  that the  retention  of the existing gas system of NSP would not
impair their ability to regulate these systems  effectively./114 With respect to
efficient  operation,  as described  below, as part of the Xcel system,  the gas
operations of New NSP, NSP-W, PSCo and Cheyenne are expected to reduce purchased
gas costs by $77.4  million from 2001 to 2010,  which will be flowed  through to
customers via lower rates in accordance with state commission approved purchased
gas  adjustment  clauses.   Far  from  impairing  the  advantages  of  efficient
operation,  the combination of the gas operations under Xcel will facilitate and
enhance the efficiency of gas operations.

----------
114  In approving  the merger of PSCo and SPS into NCE, the Colorado  Commission
     similarly  supported the retention by PSCo of its gas  operations,  and the
     Wyoming Commission similarly supported the retention by Cheyenne of its gas
     operations.

----------

     As in the 1997 NCE Order and WPL Holdings,  the proposed combination of NCE
and NSP offers  Applicants a means to compete more  effectively  in the emerging
energy services business. Further, as discussed above, the Merger will give rise
to none of the abuses,  such as  ownership of  scattered  utilities  properties,
inefficient operations, lack of local management or evasion of state regulation,
that section 11(b)(1) and the Act generally were intended to prohibit.

     While Applicants believe that the Xcel Gas Operations  constitute a single,
integrated public utility system under that is retainable under Section 11(b)(1)
of the Act,  Applicants  assert,  in the alternative,  that the Commission could
find that Xcel will have two integrated gas systems, the first consisting of its
Arizona gas  operations  (the "BMG  System")  and the second,  the  combined gas
operations  of NSP and NCE other than BMG.  The  rationale  for the  NSP-NCE gas
operations  being an  integrated  system  entitled to  retention  under  Section
11(b)(1) is explained  above.  The rationale for the retention of the BMG System
is explained below.

     As explained previously, NSP currently has pending before the Commission an
Application  in File No.  70-9337  for  approval  to  transfer  the  assets  and
operations  of BMG to a  subsidiary  of NSP.  As  explained  in  detail  in that
application  and as a background  in this  filing,  NSP acquired BMG on July 24,
1998  pursuant  to a merger  in which  BMG was  merged  into NSP with NSP as the
surviving  corporaion./115  The shareholders of the common stock of BMG approved
the merger of BMG with and into NSP at a special  meeting of BMG's  shareholders
on May 21,  1998.  The BMG Merger was  approved by the Arizona  Commission,  the
Minnesota Commission and the North Dakota Commission.  In addition, NSP obtained
approval from the Arizona  Commission,  the Minnesota  Commission  and the North
Dakota  Commission  to drop the BMG assets into a new  wholly-owned  entity that
will  be  a  first-tier  subsidiary  of  Xcel.  The  waiting  period  under  the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act")
has expired.

----------
115  Pursuant to an Agreement and Plan of Merger,  dated as of December 29, 1997
     (the "BMG Merger  Agreement"),  on July 24, 1998,  BMG merged into NSP with
     NSP as the  surviving  corporation.  A copy  of  the  Merger  Agreement  is
     incorporated  by  reference  as  Exhibit  B-4.  Pursuant  to the BMG Merger
     Agreement, each issued and outstanding share of common stock, no par value,
     of BMG ("BMG Common Stock) (except  shares owned by BMG as treasury  stock)
     was canceled and converted  into the right to receive a fraction of a share
     of common stock,  $2.50 par value, of NSP ("NSP Common Stock") equal to the
     quotient  (hereinafter,  the  "Exchange  Ratio")  derived by  dividing  (A)
     $17,750,000  by (B) the product of (i) the volume  weighted  average of the
     closing  prices for NSP Common Stock on the New York Stock Exchange for the
     twenty full trading days ending on the third full trading day prior to July
     24, 1998,  the date the Merger  became  effective  (the  "Average NSP Share
     Price")  and (ii) the  number of  shares of BMG  Common  Stock  issued  and
     outstanding  immediately prior to July 24, 1998. Pursuant to the BMG Merger
     Agreement an  additional  number of shares of NSP Common Stock equal to the
     quotient derived by dividing  $1,500,000 by the Average NSP Share Price was
     placed in escrow to satisfy any indemnification claims of NSP under the BMG
     Merger  Agreement.  Such  additional  shares,  net of  any  indemnification
     claims, were distributed pro rata to the former holders of BMG Common Stock
     on or about July 24,  1999,  the first  anniversary  of the  closing of the
     Merger.

----------

     BMG was  incorporated  under  the laws of  Arizona  in  1965.  Prior to its
acquisition  by NSP, BMG was an Arizona  public  service  corporation  providing
natural  gas  distribution  to an area of  approximately  100  square  miles  in
Maricopa County,  Arizona,  and providing propane gas distribution to an area of
approximately  20  square  miles  in  Coconino  County,  Arizona,   pursuant  to
certificates of convenience and necessity issued by the Arizona  Commission.  As
of  the  year  ended  December  31,  1999,  BMG  provided  utility  services  to
approximately   7,800   customers.   Most  of  its  customers  are  residential.
Non-residential  customers  include  two school  districts,  three  resorts  and
multiple  light  commercial  customers.  BMG's  operations  are not  subject  to
regulation  under the  jurisidiction  of the  FERC.  The  rates  charged  by BMG
(operating  as a  division  of  NSP)  to  customers  are  regulated  by  Arizona
Commission.  BMG's total  operating  revenues  for the years ended  December 31,
1997,  1998 and 1999 were  approximately  $6.2  million,  $6.3  million and $6.4
million,  respectively.  For the same peiods, BMG's net income was approximately
$1.3 million, $365,000 and $855,000,  respectively. BMG's assets was of December
31, 1997,  1998 and 1999 were  approximately  $10.3  million,  $15.5 million and
$16.6  million,  respectively.  More  detailed  information  concerning  BMG  is
contained in the Proxy  Statement of BMG dated April 23, 1998,  incorporated  by
reference as Exhibit C-4.

     For the  reasons  set  forth  in  detail  in its  Application  in File  No.
70-09337,  NSP believes that its gas utility  system,  including the BMG System,
constitutes an integrated  gas utility  system under Section  2(a)(29)(B) of the
Act. Yet, given its small size and proximity to the primary Xcel Electric System
and the other  additional  systems,  the BMG System also readily  satisfies  the
standards for retention  under the "A-B-C"  clauses of Seciton  11(b)(1).  Under
those provisions,  a registered holding company can own "one or more" additional
integrated systems if certain conditions are met.  Specifically,  the Commission
must find that the  additional  system  "cannot be  operated  as an  independent
system  without the loss of  substantial  economies  which can be secured by the
retention of control by such holding company of such system," (B) the additional
system is located in one state or adjoining  states,  and (C) the combination of
systems under the control of a single holding  company is not so large ... as to
impair the  advantages  of localized  management,  efficient  operation,  or the
effectiveness of regulation." Each of those conditions is satisfied with respect
to the BMG System.

     The  Commission  has  recently  addressed  the  retention  by a  registered
electric  system of "very small" gas operations.  At issue in Allegheny  Energy,
Inc.,  Holding Co. Act Release No. 27121 (Dec.  23, 1999),  was the retention of
gas assets with $23.7 million in gas revenues,  significantly  larger than those
of the BMG System in this matter.  Concerning the  requirements of Clause A, the
Commission stated:

          the Act does not prohibit  ownership of  combination  gas and electric
          systems,  but rather  specifies  the showings  that must be made by an
          applicant to justify ownership of such properties.  The Commission has
          addressed,  in many cases,  the question of  retainability by electric
          registered  holding  company  systems  of  additional  integrated  gas
          systems and has reached its findings  under clause A on a case-by-case
          basis, in light of the particular facts.

               The  principal  issue under clause A is whether  there would be a
          loss of substantial  economies if the additional system were divested.
          Although  Monongahela  Power did not provide the  Commission  a formal
          analysis of the gas system as a separate system,  the record permits a
          finding  that  there  would  be a loss  of  substantial  economies  if
          Monongahela  Power were required to divest the gas properties.  By any
          measure,  the gas system is very small. As noted above, the WVP system
          serves 24,000  customers.  The Commission  finds the  requirements  of
          clause A are satisfied with respect to Monongahela  Power's  ownership
          of  the  gas  properties  of  West  Virginia  Power  as an  additional
          integrated system.

The gas  operations  in this matter are smaller in every  respect  than those at
issue in Allegheny.  In addition,  association with a larger system is necessary
to  ensure  the  realization  of the  benefits  and  economies  that lead to the
acquisition  by NSP of BMG in the first  instance.  These include  corporate and
administrative efficiencies, management and operational efficiencies, purchasing
economies and enhanced technology and computer services.

     The BMG System  also  satisfies  the  requirements  of Clauses (B) and (C).
Specifically,  Arizona is  adjacent  to New Mexico and  continguous  to Colorado
where the primary Xcel Electric System  operates.  For the reasons  explained in
detail  elsewhere  in this  Application  and in  NSP's  Application  in File No.
90-09337, the combination of systems under the ownership of Xcel will not be "so
large as to impair the advantages of localized management,  efficient operation,
or the effectiveness of regulation."

(iv) Retention of Other Businesses

     In the 1997 NCE Order,  the  Commission  approved  the  retention by NCE of
certain  non-utility  businesses  of PSCo and SPS,  as well as their  direct and
indirect subsidiary companies.  Annex C sets forth those non-utility businesses.
In addition Annex C lists and describes those non-utility  businesses  commenced
by NCE following that merger. All such businesses have been established pursuant
to a Commission  order or an  applicable  exception.  As noted  previously,  the
non-utility  businesses of NSP were listed and described on Annex D. At issue in
this transaction,  is whether Xcel may retain the non-utility  businesses of NSP
and the new non-utility businesses of NCE.

     The non-utility  interests of NSP are fully retainable.  As a result of the
Merger,  the  non-utility  businesses  and interests of NSP and NCE described in
Item 1.C. above will become  businesses and interests of Xcel.  Corporate charts
showing the subsidiaries, including non-utility subsidiaries of NSP and NCE, are
filed as  Exhibits  E-10 and E-11.  A  corporate  chart  showing  the  projected
arrangement of these subsidiaries under Xcel is filed as Exhibit E-12./116

     Standard for  retention:  Section  11(b)(1)  permits a  registered  holding
company to retain  "such  other  businesses  as are  reasonably  incidental,  or
economically  necessary or  appropriate,  to the  operations of [an]  integrated
public  utility  system."  The  Commission  has  historically  interpreted  this
provision  to require an  operating  or  "functional"  relationship  between the
non-utility  activity and the system's  core  non-utility  business.  See,  e.g.
Michigan  Consolidated  Gas Co.,  Holding Co. Act  Release  No.  16763 (June 22,
1970),  aff'd,  444 F.2d 913 (D.C.  Cir.  1971);  United Light and Railways Co.,
Holding Co. Act Release No. 12317 (Jan. 22, 1954); CSW Credit, Inc., Holding Co.
Act Release No. 25995 (March 2, 1994);  and Jersey  Central Power and Light Co.,
Holding Co. Act Release No. 24348 (March 18,  1987).  The  Commission  retreated
from this historical  position and "has sought to respond to developments in the
industry by expanding its concept of a functional  relationship."/117 This shift
culminated  in the  adoption  of Rule 58. The  Commission  added  "that  various
considerations,   including  developments  in  the  industry,  the  Commission's
familiarity with the particular  non-utility activities at issue, the absence of
significant risks inherent in the particular venture,  the specific  protections
provided for  consumers  and the absence of  objections  by the  relevant  state
regulators, made it unnecessary to adhere rigidly to the types of administrative
measures" used in the past. Id.  Furthermore,  in the 1995 Report, the SEC Staff
recommended that the Commission replace the use of bright-line  limitations with
a more flexible  standard that would take into account the risks inherent in the
particular  venture and the specific  protections provided for consumers./118 In
regards to NCE's  non-utility  subsidiaries,  the Applicants are only requesting
that Xcel inherit NCE's  existing  authority,  except as noted  otherwise in the
body of this Application.  The description  provided in Annex C merely describes
the existing businesses that are retainable  pursuant to statute,  rule or order
and is not a request for expansion or  modification  of that  authority.  Xcel's
acquisition of NCE's  non-utility  subsidiaries  should be approved  because the
indirect  ownership  of  these  businesses  by  Xcel  in no  way  affects  their
functional relationship with Xcel's electric business following the Merger. Xcel
may retain NSP's non-utility  subsidiaries because, as detailed in Annex D, they
meet the statutory requirements of ownership.

----------
116  As noted before, as part of the merger integration process,  Applicants are
     currently trying to determine the optimal corporate structure for Xcel. The
     structure  reflected in EXHIBIT E-12 is thus  tentative.  In the event that
     Applicants  decide to revise the proposed  structure,  they will file it by
     amendment.

117  Exemption of Acquisition by Registered  Public-utility Holding Companies of
     Securities of Non-utility  Companies Engaged in Certain  Energy-related and
     Gas-related  Activities,  Holding Co. Act Release No. 26667 (Feb. 14, 1997)
     ("Rule 58 Release").

118  1995 Report at 81-87, 91-92.

----------

     In the past, the  Commission  has approved the  acquisition or retention of
non-utility  businesses in a merger between two  companies,  one of which was an
independent public utility company not subject to the 1935 Act and the other was
an exempt holding company.  See 1997 NCE Order,  supra. As noted above,  Annex C
sets forth the  non-utility  business of PSCo and SPS  approved  for  retention.
Applicants  submit that the  statutory  requirements  for ownership of NCE's new
non-utility  businesses  and NSP's  non-utility  businesses  are  satisfied,  as
detailed in Annexes C and D hereto.

     In approving  NCE's  retention of other  businesses,  the  Commission  also
excluded such businesses  from the limitation upon investment in  energy-related
companies under Rule 58, noting that the  restrictions  of Section  11(b)(1) are
applicable to registered  holding companies and not to exempt holding companies.
Rule  58  provides  in  section   (a)(1)(ii)  that  investments  in  non-utility
activities  that are exempt under Rule 58 cannot exceed 15% of the  consolidated
capitalization of the registered  holding company.  In its statement  supporting
the adoption of the Rule, the Commission stated:

     The  Commission  believes that all amounts that have actually been invested
     in energy-related  companies pursuant to commission order prior to the date
     of  effectiveness  of the Rule should be excluded from the  calculation  of
     aggregate  investment  under Rule 58. The  Commission  also  believes it is
     appropriate to exclude from the calculation  all investments  made prior to
     that date pursuant to available exemptions.

Holding Co. Act Release No. 26667 at 50-51. Because NSP was not yet a registered
holding  company,  none of the  investments in non-utility  activities  that are
described in Annex D hereto were pursuant to Commission  order.  However,  since
the non-utility  investments of NSP, as an exempt holding  company,  were exempt
under the Act,  investments  made by it prior to the  effective  date of Rule 58
which will continue as part of Xcel after consummation of the merger, should not
count  in the  calculation  of the  15%  maximum.  See  1997  NCE  Order,  supra
(Commission order granting exclusion of non-utility  energy-related  investments
of SPS,  an  independent  utility,  and PSCo an  exempt  holding  company,  from
calculations of the 15% maximum investment allowed under Rule 58).

     Besides the non-utility  businesses of NSP subsidiaries  that are described
in Annex B, NSP is directly engaged at the parent company level in the following
non-utility  businesses:  (i) an appliance  services program for its residential
customers,  (ii)  construction  of natural  gas  distribution  systems for third
parties (primarily end-users and municipal gas systems),  (iii) sale of steam to
industrial   customers  in  NSP's  service  territory,   (iv)  installation  and
maintenance  of street  lighting for  municipalities  and other  customers,  (v)
propane sales, (vi) fuel oil sales, and (vii) distributed  generation  services.
New NSP intends to continue to engage in these businesses.

     The following  chart shows the reasons based on Commission  orders or rules
that retention of such businesses should be permitted:

     Similarly,  PSCo,  prior to the merger with SPS into NCE, also was directly
engaged in various non-utility businesses,  namely: (i) thermal energy; (ii) the
commercialization  of  electro-technologies;  (iii)  electric  and  gas  vehicle
products  and  services;  and (iv) the sale and  servicing  of electric  and gas
appliances.  The  Commission in the 1997 NCE Order  authorized  the retention of
these businesses.  From its experience in marketing these services, NCE is aware
that there are  certain  advantages  of having a utility be able to offer  these
types of services  directly to  customers,  as opposed to through an  affiliate.
Based on this experience, Applicants request the following authorization:  where
either PSCo or the NSP companies are directly engaged in a line of business, the
retention of which the  Commission  either in the 1997 NCE Order or in its order
in this proceeding has  authorized,  the other Xcel Operating  Companies  should
likewise be authorized to engage in that business, subject to any limitations or
requirements imposed by state law or state commission order or rule.

     In addition, the Commission in the 1997 NCE Order authorized SPS, PSCo, and
other  associate  companies  of NCE to  lease  office  or  other  space to other
associate  companies (with such leases to be in accordance with Rules 87, 90 and
91) or to third  parties.  Applicants  request that the  Commission  extend this
authority  to apply to the  Xcel  system  and NSP and its  direct  and  indirect
subsidiaries.

     2.  Section 10 (c)(2)

     Because the Merger is expected to result in  substantial  cost  savings and
synergies,  it will tend toward the economical  and efficient  development of an
integrated  public  utility  system,  thereby  serving the public  interest,  as
required by Section 10(c)(2) of the Act.

     The Merger will produce  economies and efficiencies more than sufficient to
satisfy  the  standards  of Section  10(c)(2) of the Act.  Although  some of the
anticipated  economies and  efficiencies  will be fully  realizable  only in the
longer term, they are properly  considered in determining  whether the standards
of Section  10(c)(2)  have been met. See AEP,  supra.  Some  potential  benefits
cannot  be  precisely  estimated,  nevertheless  they  too  are  entitled  to be
considered.  "[S]pecific  dollar forecasts of future savings are not necessarily
required;  a  demonstrated  potential for economies will suffice even when these
are not precisely quantifiable." Centerior, supra.

     NSP and NCE have  estimated the nominal  dollar value of synergies from the
Merger to be approximately  $1.1 billion (net costs to achieve) over the 10-year
period  from  2001-2010.  The  Merger  is  expected  to yield  several  types of
presently quantifiable benefits and savings, which are identified by area below:
(1) corporate and operations support; (2) corporate and administration programs;
(3) nonfuel purchasing economies; and (4) production savings,  including savings
for fuel  procurement,  production  dispatch  and natural gas supply.  The total
amount of savings currently estimated in each of these categories,  on a nominal
dollar basis is summarized in the table below:

                       Merger Synergies in Nominal Dollars

     These  expected  savings will meet or exceed the  anticipated  savings in a
number of recent acquisitions  approved by the Commission./119 See, e.g., NIPSCO
Industries,  Inc.,  Holding Co. Act Release No. 26975 (Feb. 10, 1999)  (expected
savings of $57.45  million  over ten  years);  Sempra  Energy,  Holding  Co. Act
Release No.  26890 (June 26,  1998)  (expected  savings of $1.2 billion over ten
years);  BL Holding  Corp.,  Holding Co. Act Release  No.  26875 (May 15,  1998)
(expected  savings of $1.1 billion over ten years);  LG&E Energy Corp.,  Holding
Co. Act Release No. 26866 (April 20, 1998)  (expected  savings of $687.3 million
over ten years);  WPL  Holdings,  Holding Co. Act Release No.  26856  (April 14,
1998) (expected savings of $680 million over ten years);  Conectiv,  Holding Co.
Act Release No. 26856 (Feb. 25, 1998) (expected savings of $500 million over ten
years);  Ameren  Corporation,  supra (expected  savings of $686 million over ten
years); 1997 NCE Order, supra (expected savings of $770 million over ten years);
TUC Holding  Company,  supra (expected  savings of $505 million over ten years);
Northeast Utilities, supra (expected savings of $837 million over eleven years);
Entergy Corporation, Holding Co. Act Release No. 25952 (Dec. 17, 1993) (expected
savings of $1.67 billion over ten years);  Northeast Utilities,  Holding Co. Act
Release No. 25221 (Dec. 21, 1990) (expected  savings of $837 million over eleven
years);  Kansas Power and Light Co.,  Holding Co. Act Release No. 25465 (Feb. 5,
1992) (expected savings of $140 million over five years); IE Industries, Holding
Co. Act Release No. 25325 (June 3, 1991)  (expected  savings of $91 million over
ten years);  Midwest  Resources,  Holding Co. Act Release No. 25159  (Sept.  26,
1990) (expected savings of $25 million over five years);  CINergy Corp., Holding
Co. Act Release No. 26146 (Oct.  21, 1994)  (expected  savings of  approximately
$1.5 billion over ten years).  These savings categories are described in greater
detail below.

----------
119  Further,  the Applicants  anticipate an additional $24 million in operating
     efficiencies due to the integration plans as described below.

----------

     Corporate and Operations Support: NCE and NSP estimate that a net reduction
in labor costs of approximately $691 million over ten years can be achieved as a
result  of the  Merger  through  elimination  of  approximately  780  full  time
equivalent  duplicative  positions  (including 105 contract  workers) in certain
corporate, administrative and technical support functions.

     Corporate and Administrative  Programs: NSP and NCE estimate a reduction in
nonlabor  corporate  and  administrative   programs  and  expenses  through  the
consolidation  of  overlapping  or  duplicative  programs  and  expenses of $344
million over ten years.  Specific  areas in which  savings are expected to occur
include  information  systems,  professional  services,  demand-side  management
administration,   benefits  administration,   insurance,   regulatory  expenses,
advertising and shareholder services.

     Nonfuel  Purchasing  Economies:  NSP and NCE  estimate  savings  of  $203.7
million  through the combined  procurement  of material and supplies,  inventory
reduction from standardization,  and limited sharing of parts and components and
from  economies of scale from the  aggregation  of related work  activities  and
increased purchasing power over service providers.

     Production   Savings:   NSP  and  NCE   estimate   production   savings  of
approximately  $96 million over a ten-year  period.  Two main components make up
total  production  savings:  efficiencies  in  procurement  of  fossil  fuel and
efficiencies in procurement and management of natural gas supply. The Applicants
estimate fossil fuel savings of $18.5 million, stemming from an increase in coal
procurement and coal transportation volumes and greater leverage during contract
negotiations.  NSP and NCE estimate  natural gas supply savings of approximately
$77.4  million,  based on gas transport  and storage  capacity  reductions,  gas
reserve margin reductions,  field transportation reductions and capacity release
savings through the contemplated gas supply coordinated dispatch agreement.

     The foregoing amounts do not include an additional $24 million in operating
efficiencies that the Applicants expect to achieve over ten years as a result of
the integration of the NSP and NCE electric  generation  systems through the 100
MW firm  path  from  SPS to NSP.  Through  the use of this  contract  path,  the
Applicants estimate  approximately $31 million in production cost savings and an
additional $10 million in benefits  resulting from increased  opportunity sales.
The firm path would also provide a secure source of additional  low-cost  supply
to NSP during NSP's peak  periods,  protecting  NSP from some  predicted  energy
price volatility. These expected benefits are offset by anticipated transmission
costs,  resulting  in an expected  net benefit of $24 million  over the ten-year
period. As noted before, in their application to FERC,  Applicants  reserved the
right to forego this firm path in the event that FERC believed that  competitive
concerns related to the path raised material issues of fact that would require a
hearing.  For this reason, these additional $24 million of savings have not been
included in the $1.1 billion of savings  presented  in the chart above.  Because
the FERC Merger Order did not require that  Applicants  forego this path,  these
additional savings should also be achievable.

     Additional Expected Benefits:  In addition to the benefits described above,
there are other  benefits  which,  while  presently  difficult to quantify,  are
nonetheless substantial. These other benefits include maintenance of competitive
rates,  expanded  management  resources,  more  diverse  service  territory  and
continued community involvement.

     Maintenance of Competitive  Rates: A combined  NSP/NCE will be able to meet
the  challenges  of the  increasingly  competitive  environment  in the  utility
industry more effectively than either NCE or NSP standing alone. The Merger will
create the  opportunity for strategic,  financial and  operational  benefits for
customers in the form of lower rates over the long term and for  shareholders in
the form of greater financial  strength and financial  flexibility.  NCE and NSP
have  proposed in filings with the various  state  regulatory  commissions  that
regulate  their  retail  sales of  electricity  various  mechanisms  to share in
contemplated  benefits,  including a three- to five-year  rate freeze.  The rate
freezes are subject to certain exceptions  regarding matters beyond the NSP's or
NCE's  control.  Further,  ratepayers  will  receive  100%  of  the  benefit  of
reductions in Xcel's fuel costs,  except that customers of PSCo will receive 50%
of such benefit.

     Expanded Management  Resources:  A combined NCE and NSP entity will be able
to draw on a larger and more diverse mid- and  senior-level  management  pool to
lead the new company forward in an increasingly  competitive environment for the
delivery  of energy,  and should be better  able to attract  and retain the most
qualified  employees.  The  employees  of Xcel  should  also  benefit  from  new
opportunities in the expanded organization.

     More Diverse Service Territory: The combined service territories of NSP and
NCE will be larger and more  diverse than either of the service  territories  of
NSP or NCE as independent entities.  This increased  geographical diversity will
mitigate the risk of changes in economic,  competitive or climatic conditions in
any given sector of the combined service territory.

     Community  Involvement:  Xcel will  continue  to play a strong  role in the
economic  development  efforts of the  communities  NSP and NCE now  serve.  The
philanthropic and volunteer programs  currently  maintained by the two companies
will be continued.

D.   Section 10(f)

     Section 10(f) provides that:

     The Commission shall not approve any acquisition as to which an application
     is made under this  section  unless it appears to the  satisfaction  of the
     Commission that such State laws as may apply in respect of such acquisition
     have been complied with,  except where the Commission finds that compliance
     with such  State  laws  would be  detrimental  to the  carrying  out of the
     provisions of section 11.

     As described below under Item 4.  "Regulatory  Approvals," and as evidenced
by the filings before the Minnesota Commission, the North Dakota Commission, the
Colorado  Commission,  the Arizona  Commission,  the New Mexico Commission,  the
Texas Commission,  and the Wyoming Commission, NSP and NCE intend to comply with
all applicable state laws related to the proposed Merger.

E.   Intra-system Transactions

     The  Xcel  system   companies   will  engage  in  a  variety  of  affiliate
transactions for the provision of goods, services, and construction.  Certain of
these transactions are elaborated upon below. In some instances,  the Applicants
simply request  extension of the  authorizations  granted in the 1997 NCE Order,
with  respect to the NCE system,  to the Xcel  system.  The  provision of goods,
services  and  construction  by Xcel  system  companies  to  other  Xcel  system
companies will be carried out in accordance with the requirements and provisions
of Rules 87, 90 and 91 unless otherwise authorized by the Commission by order or
by rule./120

----------
120  As stated previously, the electric production and transmission costs of NSP
     and NSP-W are shared by them in accordance with the Interchange  Agreement,
     which is a  FERC-regulated  agreement  that has also been  accepted  by the
     Wisconsin  Commission  and the Minnesota  Commission for  determination  of
     costs recoverable in rates by NSP-W and NSP in rate cases.

----------

1.   New Century Services, Inc. (to be renamed Xcel Energy Services Inc.)

     Rule 88(b) provides that "[a] finding by the  Commission  that a subsidiary
company of a registered holding company. . .is so organized and conducted, or to
be so conducted,  as to meet the  requirements  of Section 13(b) of the Act with
respect to  reasonable  assurance of efficient  and  economical  performance  of
services  or  construction  or  sale  of  goods  for the  benefit  of  associate
companies, at cost fairly and equitably allocated among them (or as permitted by
[Rule]  90),  will be  made  only  pursuant  to a  declaration  filed  with  the
Commission on Form U-13-1,  as specified in the  instructions  for that form, by
such  company or the persons  proposing  to organize  it."  Notwithstanding  the
foregoing  language,  the  Commission in the 1997 NCE Order made findings  under
Section 13(b) based on information  set forth in an  Application-Declaration  on
Form  U-1,  without  requiring  the  formal  filing  of a Form  U-13-1.  In this
Application-Declaration, Applicants are submitting substantially the application
information  as would have been  submitted in a Form U-13-1.  Moreover,  in this
application,  Applicants  are not  requesting  authorization  to establish a new
service  company,  but rather are requesting  that the  Commission  authorize an
existing,  Commission-approved  service company, New Century Services, to extend
its  activities  to NSP and its direct and indirect  subsidiaries  following the
consummation of the Merger and the formation of the Xcel system.

     Accordingly,  it is  submitted  that it is  appropriate  to find  that  New
Century  Services  will be so organized and shall be so conducted as to meet the
requirements  of  Section  13(b),  and  that  the  filing  of a Form  U-13-1  is
unnecessary,  or,  alternatively,  that this  Application-Declaration  should be
deemed to constitute a filing on Form U-13-1 for purposes of Rule 88.

     New Century  Services will be the service  company  subsidiary for the Xcel
system.  Specifically,  New Century  Services will provide Xcel, New NSP, NSP-W,
BMG, PSCo, SPS, and Cheyenne, pursuant to the Utility Service Agreement, and the
non-utility  subsidiaries  of the NSP/NCE  system  pursuant  to the  Non-Utility
Service Agreement, with one or more of the following: administrative, management
and support services, including services relating to support of electric and gas
plant operations  (i.e.,  energy supply management of the bulk power and natural
gas supply,  procurement of fuels, dispatch of generating units, coordination of
electric and natural gas  distribution  systems,  maintenance,  construction and
engineering work);  customer bills, and related matters;  materials  management;
facilities;  real estate; rights of way; human resources;  finance;  accounting;
internal auditing;  information systems; corporate planning and research; public
affairs;  corporate communications;  legal; environmental matters; and executive
services.  In accordance with the Service  Agreement,  services  provided by New
Century  Services  will  be  directly  assigned,  distributed  or  allocated  by
activity, project, program, work order or other appropriate basis. To accomplish
this,  employees of New Century Services will record their labor and expenses to
bill the appropriate  subsidiary company.  Costs of New Century Services will be
accumulated  in  accounts  of the  service  company  and be  directly  assigned,
distributed,  or allocated to the appropriate  client company in accordance with
the guidelines set forth in the Utility  Service  Agreement and the  Non-Utility
Service Agreement and the procedures in the "Procedures Manual" included but not
incorporated  with  ExhibitS  B-2 and  B-3.  As part of the  merger  integration
process,  Applicants  evaluated the existing forms of service  agreement and the
allocation  methodologies  currently  being  used  by New  Century  Services  to
determine whether they should be revised to reflect the introduction of New NSP,
NSP-W,  or any of NSP's present  subsidiaries  as recipients of services.  While
Applicants  did not alter the forms of service  agreements,  some revisions were
made to the  allocation  methodologies  and  are  reflected  in the  "Procedures
Manual"  referenced  above.  There will be an internal audit group which,  among
other things,  will audit the  assignment of service  company  charges to client
companies. It is anticipated that New Century Services will be staffed primarily
by existing  personnel and by transferring  personnel from the current  employee
rosters of NSP and its subsidiaries.  New Century Services's accounting and cost
allocation  methods  and  procedures  are  structured  so as to comply  with the
Commission's  standards  for service  companies in  registered  holding  company
systems and were approved by the Commission in the 1997 NCE Order.

     It  is  expected  that  New  Century  Services  will  conduct   substantial
operations  in  Minneapolis  and St.  Paul,  Minnesota;  Eau Claire,  Wisconsin;
Denver,  Colorado;  and Amarillo,  Texas,  where the headquarters of NSP, NSP-W,
PSCo and SPS are located.  Merger  transition  teams are  presently  considering
where specific operations of the combined company will be headquartered.

     As  compensation  for services,  both the Utility and  Non-Utility  Service
Agreements provide that "each Client Company shall pay to Service Company [i.e.,
New Century Services] the cost to Service Company of rendering such services for
or on its  behalf."  Where more than one company is involved in or has  received
benefits from a service  performed,  the Service Agreement will provide that the
"methods of assigning, distributing, or allocating Service Company costs to each
Client  Company,  as well as to  other  associate  companies,  are set  forth in
Appendix A. . . . Such methods of  assignment,  distribution  or  allocation  of
costs may be modified or changed by Service  Company without the necessity of an
amendment to this Service Agreement provided that in such instance, all services
rendered  hereunder  shall be at  actual  cost  thereof,  fairly  and  equitably
assigned,  distributed or allocated,  all in accordance with the requirements of
the [Public  Utility  Holding  Company]  Act and any orders  thereunder."  Thus,
charges for all services provided by New Century Services to affiliated  utility
companies will be as determined under Rules 90 and 91 of the Act.

     The Non-Utility  Service Agreement contains  provisions similar to those of
the Service  Agreement,  except as set forth in detail below in this Item 3.E.3.
The Non-Utility  Service Agreement also will permit charges for certain services
to be at fair market value to the extent  authorized  by the 1997 NCE Order,  or
hereafter by the Commission.  Thus,  except for the prior exemptions in the 1997
NCE Order and the requested exceptions discussed below, services provided by New
Century Services to non-utility  affiliates  pursuant to the Non-Utility Service
Agreement  will also be charged as determined  under Rules 90 and 91 of the Act.
For further information  regarding the accounting and cost assignment procedures
of New Century Services, reference is made to EXHIBITS B-2 and B-3 hereto./121

----------
121  NSP's agreement with a subsidiary,  NMC,  states that services  provided to
     NMC or received  from NMC be at the higher of cost or market,  or lower the
     cost or market, respectively.  However, that agreement also deems market to
     equal cost and thus is consistent with SEC requirements.

----------

     Moreover,  the Utility and Non-Utility  Service  Agreements provide that no
change in the  organization of New Century  Services,  the type and character of
the  companies  to be  serviced,  the methods of  allocating  costs to associate
companies,  or in the scope or character of the services to be rendered  subject
to Section 13 of the Act, or any rule, regulation or order thereunder,  shall be
made unless and until New Century Services shall first have given the Commission
written  notice  of the  proposed  change  not  less  than 60 days  prior to the
proposed  effectiveness  of any such  change.  If,  upon the receipt of any such
notice,  the  Commission  shall  notify New Century  Services  within the 60-day
period that a question  exists as to whether the proposed  change is  consistent
with the  provisions  of Section 13 of the Act,  or of any rule,  regulation  or
order thereunder, then the proposed change shall not become effective unless and
until New Century  Services  shall have filed with the Commission an appropriate
declaration  regarding  such  proposed  change  and the  Commission  shall  have
permitted such declaration to become effective.

     Applicants  believe that the Utility Service  Agreement and the Non-Utility
Service  Agreement are structured so as to comply with Section 13 of the Act and
the Commission's rules and regulations thereunder.

2.   Services, Goods, and Assets Involving the Utility Operating Companies

     PSCo, SPS, Cheyenne,  New NSP, NSP-W and BMG may provide to one another and
other  associate  companies  services  incidental to their  utility  businesses,
including but not limited to, power plant maintenance overhauls, power plant and
storm outage  emergency  repairs,  and services of  personnel  with  specialized
expertise  related  to  the  operation  of the  utility  (i.e.,  services  by an
industrial  lighting  specialist or waste disposal  specialist).  These services
will be provided in accordance with Rules 87, 90 and 91. Moreover, in accordance
with  Rules  87, 90 and 91,  certain  goods  may be  provided  through a leasing
arrangement  or  otherwise  by one  utility  operating  company  to one or  more
associate  companies,  and certain  assets may be used by one utility  operating
company for the benefit of one or more other associate companies.

     In addition to the foregoing,  NSP and NSP-W are currently  providing goods
and services to, or receiving goods and services from,  affiliates in accordance
with  agreements  approved  by the  Minnesota  Commission  and/or the  Wisconsin
Commission.  Each of these  contracts  (including  the  parties) is described in
Annex  E. To the  extent  necessary,  Applicants  request  that  the  Commission
grandfather these pre-existing arrangements to enable the provision of goods and
services to continue  post-Merger.  As indicated in Annex E, Applicants  believe
that the pricing of such transactions is in compliance with, or exempt from, the
Commission's  rules.  However,  in the  event  that  the  Commission  disagrees,
Applicants also request that with respect to such  arrangements,  the Commission
grant an  exemption  for the  pricing of such  transactions  to the extent  such
pricing varies from the Commission's at-cost standard under Section 13(b) of the
Act./122

     To elaborate  on the  requested  exemption  from the  Commission's  at-cost
standard, Minnesota law specifies as follows:

          no  contract  or  arrangement,  including  any  general or  continuing
          arrangement, providing for the furnishing of management,  supervisory,
          construction,  engineering,  accounting,  legal,  financial or similar
          services and no contract or arrangement for the purchase,  sale, lease
          or exchange of any property,  right or thing, or for the furnishing of
          any  service,  property,  right  or  thing,  other  than  those  above
          enumerated,  made or  entered  into after  January 1, 1975,  between a
          public  utility and any  affiliated  interest...is  valid or effective
          unless and until the contract or arrangement  has received the written
          approval of the [Minnesota Public Utilities] commission./123

An  "affiliated  interest"  includes  every  subsidiary  of  a  public  utility.
Furthermore  Minnesota  law  provides  that "the  [Minnesota  Public  Utilities]
Commission shall approve the contract or  arrangement...only if it shall clearly
appear  and  be  established  upon  investigation  that  it  is  reasonable  and
consistent with the public  interest...," with the utility bearing the burden of
proving that it is in the public interest./124

     Under a policy  statement issued in Docket No.  E,G-999/CI-90-1008  (1994),
the Minnesota  Commission had adopted extensive  guidelines on the allocation of
costs for transactions with nonregulated affiliates. The Policy Statement docket
initially arose from an  investigation of nonregulated  utility  appliance sales
and service programs. However, the Minnesota Commission later expanded the scope
of the docket, and the Policy Statement also applies to all utility arrangements
with regulated and nonregulated  affiliates./125 The Policy  Statement  provides
that costs  should be assigned  between the utility and  non-regulated  function
using the following four step hierarchy:

----------
122  Applicants  believe that the one contract  specified in Appendix E that has
     been approved by the Wisconsin  Commission  fully comports with the at-cost
     standard.  Therefore,  Applicants  do not request the same  exemption  with
     respect to that contract.

123  ss.216B.48, subdivision 3 (Supp. 1993).

124  Id.

125  In MPUC Docket No. G002/M-94-831,  the MPUC again expanded the scope of the
     Policy  Statement,  indicating  it would be applied to assign costs between
     NSP utility operations and regulated affiliates (such as Viking).

----------

     1.   Tariffed  rates shall be used to value tariffed  services  provided to
          the non-regulated activity.

     2.   Costs shall be directly  assigned to either regulated or non-regulated
          activities whenever possible.

     3.   Costs which  cannot be directly  assigned are common costs which shall
          be grouped into cost categories. Each cost category shall be allocated
          based on direct analysis of the origin of costs wherever possible.  If
          direct analysis is not possible, common costs shall be allocated based
          upon an indirect  cost-causative  linkage to another cost  category or
          group of cost categories for which direct  assignment or allocation is
          available.

     4.   When neither  direct nor indirect  measures of cost  causation  can be
          found,  the cost  category  shall be  allocated  based  upon a general
          allocator  computed by the ratio of all expenses  directly assigned or
          attributed to regulated and  non-regulated  activities,  excluding the
          cost of fuel, gas, purchased power and the cost of goods sold.

Under  this  hierarchy,  costs  are  generally  allocated  to  non-regulated  or
regulated  affiliates on a "fully allocated cost" basis, in order to prevent any
subsidy of non-utility  operations by the regulated  utility  operations and its
customers.  Accordingly,  Applicants believe that most of the NSP contracts that
have been  reviewed and approved by the  Minnesota  Commission  comport with the
Commission's at-cost standard. However, to the extent that there is any variance
between at-cost pricing under the Minnesota  Commission's  policies and Rules 90
and 91 of  the  Commission's  rules,  Applicants  request  that  the  Commission
grandfather the existing arrangements and exempt those contractual  arrangements
from the at-cost  standard of Section  13(b) of the Act so that they may stay in
effect for New NSP as the successor of NSP.

     Applicants believe that the requested  exemptions from the at-cost standard
of  Section  13(b),   allowing  for  these   contracts  to  be  continued  on  a
grandfathered  basis,  are  in the  public  interest.  For  each  contract,  the
Minnesota  Commission has determined  that the contract is reasonable and in the
public interest.  The Commission's principal concern under Section 13 of the Act
is to  protect  utility  companies  in a holding  company  system  from  abusive
cross-subsidization   transactions  between  associate   companies.   Since  the
Minnesota  Commission has found that the applicable contracts listed in Appendix
E are reasonable and in the public interest,  cross-subsidization  issues do not
arise under these agreements, and each should be permitted to continue.

     In  requesting  exemption  from the  at-cost  standard  of  Section  13(b),
Applicants  emphasize  that the  exemptions  are only  intended to allow for the
continuation of existing  contractual  arrangements on a grandfathered basis. In
the event that New NSP or NSP-W wish to enter  into new  affiliate  arrangements
that would necessitate an exemption from the Commission's at-cost standard, they
will first make an appropriate application to the Commission.

     In addition to the contracts listed in Annex E, New NSP will obtain nuclear
plant  operations  services  from Nuclear  Management  Company,  LLC ("NMC"),  a
Wisconsin  limited liability  company.  NMC was formed in February 1999 by three
unaffiliated  companies,  namely,  NSP,  WEC  Nuclear  Corp.,  a  subsidiary  of
Wisconsin Energy Corporation,  and WPS Nuclear Corporation,  a subsidiary of WPS
Resources, which own (or whose affiliates own) nuclear power plant units located
in  Wisconsin  and  Minnesota  (the  "NMC  Plant  Owners")  for the  purpose  of
consolidating into one service  organization the specialized nuclear power plant
personnel  and  resources  of such  companies.  NSP owns a 25%  interest  in NMC
through an  affiliate,  NSP  Nuclear  Corporation,  that was formed to hold this
interest.  NMC is providing to, and  receiving  from,  NMC Plant Owners  various
services pursuant to two agreements. First, the NMC Services Agreement lists ten
categories of support services,  such as fuel procurement and maintenance,  from
which NMC may provide the NMC Plant  Owners  support  services on a  centralized
basis.  Each NMC  Plant  Owner  has the  right  not to take  services  under the
Services  Agreement  and NMC may  offer  additional  services  to the NMC  Plant
Owners. Second, as an NMC Plant Owner, NSP, in accordance with an Employee Lease
Agreement, is providing NMC services and specialized personnel to facilitate its
provision of services  back to it and the other NMC Plant  Owners.  All services
under these  agreements are provided to the recipient of the services at cost in
accordance with Rules 90 and 91. NSP has received Minnesota  Commission approval
of the Services Agreement and Employee Lease  Agreement./126 Also by order dated
October 26, 1999 (Holding Co. Act Release No. 27096), the Commission  authorized
Alliant Energy Corporation to acquire a 25% membership  interest in NMC, and IES
Utilities,  Inc.,  a  subsidiary  of Alliant  Energy,  to enter into the Service
Agreement and the Employee Lease  Agreement.  Applicants seek permission for New
NSP (as  successor of NSP) to engage in business with NMC under the NMC Services
Agreement  and the NMC  Employee  Lease  Agreement  as  grandfathered  affiliate
agreements approved by the Minnesota Commission,  or alternatively,  pursuant to
the relief granted to Alliant Energy in the Commission's Release No. 27096.

     Additionally,  NSP recently  received  Minnesota  Commission  approval of a
Nuclear  Power  Plant  Operating   Services   Agreement   ("Operating   Services
Agreement")./127  When all  necessary  regulatory  approvals  for all NMC  Plant
Owners  are  received,  NMC  will  provide  operations,   maintenance,   capital
improvement and  decommissioning  services to the NMC Plant Owners including New
NSP under this agreement.  NMC will provide these services at cost in accordance
with Rules 90 and 91. By order dated May 10, 2000  (Holding  Co. Act Release No.
27175),  Alliant Energy has also  requested  approval of the Nuclear Power Plant
Operating  Services  Agreement.  Applicants  request  permission  for New NSP to
engage  in  business  with NMC  under  the  Operating  Services  Agreement  as a
grandfathered  affiliate  agreement  approved by the  Minnesota  Commission  or,
alternatively,  pursuant  to  the  relief  granted  to  Alliant  Energy  in  the
Commission's Release No. 27175.

127  Docket E-002\AI-99-1652 (February 4, 2000).

----------

     Finally,  in  the  1997  NCE  Order,  the  Commission   authorized  Utility
Engineering  Corporation  ("UE") to perform  engineering,  development,  design,
construction,  and other related services to operating  companies within the NCE
system on an at-cost  basis.  The  Commission  contemplated  that UE may provide
those services to individual  operating  companies  pursuant to agreements  with
such companies,  or may contract with New Century Services,  which could in turn
provide the services to associate companies  including the operating  companies.
Applicants  request that this authority be extended to enable UE to provide such
services on an at-cost basis to the operating companies within the Xcel system.

3.   Non-Utility Sale of Goods and Services to EWGs, FUCOs, and QFs

     The Commission has authorized the nonutility subsidiaries of NCE (including
New Century Services),  whether then existing or thereafter  created, to provide
goods and services to any "Client  Company"  under an exemption from the at-cost
standard of Section 13(b) where:

        (i)    the Client Company is a FUCO or foreign EWG which derives no part
               of its  income,  directly  or  indirectly,  from the  generation,
               transmission,  or distribution of electric energy for sale within
               the United States;

        (ii)   the  Client  Company  is  an  EWG  which  sells   electricity  at
               market-based rates which have been approved by the Federal Energy
               Regulatory  Commission  ("FERC"),  provided that the purchaser is
               not a utility operating company within the NCE system (a "Utility
               Subsidiary");

        (iii)  the  Client  Company  is a QF within  the  meaning  of the Public
               Utility  Regulatory  Policies  Act of 1978  ("PURPA")  that sells
               electricity  exclusively (a) at rates  negotiated at arms' length
               to one or more industrial or commercial customers purchasing that
               electricity  for their own use and not for resale,  and/or (b) to
               an electric  utility  company other than a Utility  Subsidiary at
               the  purchaser's  "avoided cost" as determined in accordance with
               the regulations under PURPA; or

        (iv)   the Client Company is a domestic EWG or QF that sells electricity
               at rates based upon its cost of  service,  as approved by FERC or
               any state public utility commission having jurisdiction, provided
               that the purchaser is not a Utility Subsidiary.

     See New Century  Energies,  Inc.,  Holding Company Act Release No. 35-27000
(issued in File No. 70-9397 on April 7, 1999)  (reaffirming a similar  exemption
granted  in the 1997  Order)  (the "1999  Order").  Applicants  request  similar
authorization  for the nonutility  subsidiaries of Xcel (whether now existing or
hereafter  created) to provide goods and services to Client Companies within the
Xcel  system  meeting the above  criteria  under an  exemption  from the at-cost
standard of Section 13(b).

     In File No. 70-9397 NCE had also requested that ETCs, Rule 58 subsidiaries,
and  nonutility  subsidiaries  that do not derive any part of their  income from
sales of goods,  services or other  property to a Utility  Subsidiary  be deemed
Client  Companies  for  purposes  of this  exemption.  In the  1999  Order,  the
Commission reserved jurisdiction over that request.  Applicants request that the
Commission  either (i) expand the exemption to apply to such companies as Client
Companies  within  the  Xcel  system  following  the  merger;  or  (ii)  reserve
jurisdiction  over that request in this  proceeding  pending  completion  of the
record.

     In addition to the general  exemption from the at-cost  standard  described
above, Applicants also, to the extent necessary, request a waiver of the at-cost
standard with respect to services that UE and Quixx Power Services, Inc. ("QPS")
may provide to a QF located at the  Phillips  Petroleum  Refinery  Complex  near
Borger,  Texas,  that will sell power to SPS pursuant to a power sale  agreement
(the  "QF  PPA").  This QF is held  by a  limited  partnership  in  which  Quixx
Corporation ("Quixx"),  an indirect subsidiary of NCE and therefore an affiliate
of SPS,  has a 50%  interest.  UE has  provided  and may in the  future  provide
engineering  and  construction  services for the facility.  QPS, a subsidiary of
Quixx,  is providing  operations and  maintenance  services to the facility at a
negotiated market-based rate pursuant to an operating agreement.  The Commission
approved an exemption  from the at-cost  standard for these services in the 1997
NCE Order. The basis for the exemption was that SPS, utilizing a bidding process
supervised by an  independent  bid examiner  pursuant to guidelines of the Texas
Commission, selected the QF PPA as the most economic manner to satisfy projected
power needs.  Applicants request that the Commission,  as necessary,  extend the
existing exemption to the at-cost standard of section 13(b) to enable UE and QPS
to provide  services for the QF at negotiated  terms and  conditions  (including
prices) post-Merger.

F.   Capitalization of New NSP

     The Applicants request authority to organize a new utility subsidiary,  New
NSP, under the laws of Minnesota and to take the following actions in connection
with the organization and  capitalization of New NSP: New NSP proposes to assume
the debt of NSP existing at the time of the Merger  (approximately $2.0 billion)
and issue  shares of its capital  stock to Xcel.  The equity  component  will be
derived by  subtracting  the total debt being  assumed by New NSP from the total
assets being  transferred  to New NSP.  The result of the  foregoing is that the
overall equity/debt ratio New NSP will be approximately 50%, which is similar to
that of NSP  prior  to  consummation  of the  Merger.  Applicants  also  request
authority  for  Xcel to  acquire  the  capital  stock  of New NSP and for NSP to
transfer its debt to New NSP.

Item 4.  Regulatory Approvals

     Set forth below is a summary of the regulatory  approvals  that  Applicants
have  obtained  or  expect  to obtain in  connection  with the  Merger.  It is a
condition  to the  consummation  of the Merger that final orders  approving  the
Merger  be  obtained  from the  Commission  under  the Act and from the  various
federal and state  commissions  described  below on terms and  conditions  which
would not have,  or would not be reasonably  likely to have, a material  adverse
effect on the business,  assets, financial condition or results of operations of
NCE and its subsidiaries  taken as a whole, or on NSP and its subsidiaries taken
as a whole.

A.   Antitrust

     The HSR Act and the  rules  and  regulations  thereunder  prohibit  certain
transactions (including the Merger) until certain information has been submitted
to the Antitrust Division of the Department of Justice ("DOJ") and Federal Trade
Commission  ("FTC") and the specified HSR Act waiting period  requirements  have
been satisfied. The HSR Act waiting period expired on March 1, 2000.

     The  expiration or earlier  termination  of the HSR Act waiting period does
not  preclude  the DOJ or the FTC  from  challenging  the  Merger  on  antitrust
grounds.  Applicants  believe that the Merger will not violate Federal antitrust
laws. If the Merger is not consummated within twelve months after the expiration
or earlier  termination of the initial HSR Act waiting period,  NSP and NCE will
be required to submit new  information to the DOJ and the FTC, and a new HSR Act
waiting period would begin and have to expire or be terminated before the Merger
could be consummated.

B.   Federal Power Act

     Section 203 of the Federal Power Act provides that no public  utility shall
sell or  otherwise  dispose of its  jurisdictional  facilities  or  directly  or
indirectly  merge or consolidate  such facilities with those of any other person
or acquire any  security  of any other  public  utility,  without  first  having
obtained  authorization  from FERC.  Under Section 203 of the Federal Power Act,
FERC will approve a merger if it finds that merger  "consistent  with the public
interest."  In reviewing a merger,  FERC  generally  evaluates:  (i) whether the
merger will adversely affect competition, (ii) whether the merger will adversely
affect  rates,  and (iii)  whether the merger will impair the  effectiveness  of
regulation. On July 30, 1999, NSP and NCE filed a combined application with FERC
requesting  FERC to approve the Merger  under  Section 203 of the Federal  Power
Act. In connection  with this  Application,  NSP and NCE also filed a joint Open
Access  Transmission  Tariff to be effective  upon  completion of the Merger and
Joint Operating  Agreement and proposed  Statement of Policy and Code of Conduct
applicable  to  certain  wholesale  merchant  function  operations  and  various
subsidiaries  under  Section 205 of the Federal  Power Act, to become  effective
upon consummation of the Merger. As explained  previously,  on January 12, 2000,
FERC  issued its order  approving  the Merger  under  Section 203 of the Federal
Power Act.  As part of its order,  the FERC also  accepted  the Joint  Operating
Agreement for filing without modification,  the proposed Statement of Policy and
Code of Conduct  without  modification  and the Joint Open  Access  Transmission
Tariff for filing,  subject to a pending  separate  proceeding  regarding  SPS's
rates. In addition, Applicants separately filed under 18 C.F.R. Part 37 proposed
revised  Standards  of Conduct for NSP,  PSCo,  Cheyenne and SPS to be effective
during the pendency of and after the proposed Merger.  NSP also needed to obtain
FERC's  authorization  under  Part  I of  the  Federal  Power  Act  to  transfer
hydro-electric   licenses   held  by  it  to  New  NSP,  and  to  obtain  FERC's
authorization  under  Section  205 of the  Federal  Power Act to amend  existing
wholesale  contracts  to  have  New NSP  assume  NSP's  responsibilities.  These
authorizations have been obtained,  subject to a notice filing to be made within
30 days after closing of the Merger.

C.   Atomic Energy Act

     NSP holds NRC  operating  licenses in  connection  with its  ownership  and
operation of the Prairie Island and Monticello  nuclear  generating  facilities.
The operating  licenses  authorize NSP to own and operate the  facilities.  PSCo
holds NRC  licenses  in  connection  with its  ownership  of the Fort St.  Vrain
Nuclear  Electric  Generating  Station.  The  Fort  St.  Vrain  facility  ceased
operations on August 29, 1989 and is in the process of being  decommissioned  in
accordance  with the terms of orders  issued by the NRC.  The Atomic  Energy Act
provides that a license or any rights  thereunder  may not be  transferred or in
any manner disposed of, directly or indirectly,  to any person through  transfer
of control  unless the NRC finds that such  transfer is in  accordance  with the
Atomic  Energy Act and consents to the  transfer.  Pursuant to the Atomic Energy
Act,  NSP has applied for  approval  from the NRC to reflect the fact that after
the  Merger,  New NSP will own and operate  the  Prairie  Island and  Monticello
facilities and will become the operating company  subsidiary of such facilities.
NRC approval of NSP's application occurred on May 12, 2000.

D.   State Public Utility Regulation

     NSP is currently  subject to the jurisdiction of the Minnesota  Commission,
the  North  Dakota  Commission,  the South  Dakota  Commission  and the  Arizona
Commission. NSP-W is subject to the jurisdiction of the Wisconsin Commission and
the  Michigan  Commission.  BMG is subject to the  jurisdiction  of the  Arizona
Commission.  PSCo is subject to the  jurisdiction  of the  Colorado  Commission.
Cheyenne  is subject  to the  jurisdiction  of the  Wyoming  Commission.  SPS is
subject to the jurisdiction of the New Mexico Commission,  the Texas Commission,
the  Kansas  Commission  and the  Oklahoma  Commission.  NSP and NCE have  filed
applications  for  approval  of the  Merger,  including  (where  necessary)  the
issuance  of  securities,  with  the  Minnesota  Commission,  the  North  Dakota
Commission,  the Arizona  Commission,  the Colorado  Commission,  the New Mexico
Commission and the Wyoming Commission. Approval of the Merger is not required in
Texas. However, unless the Texas Commission determines that the Merger is in the
public  interest,  the Texas  Commission  may take its findings  into account in
future  rate  making  proceedings.  Thus,  NSP and NCE also filed with the Texas
Commission  for a  determination  that the  Merger  is in the  public  interest.
Approval of the Merger is not  required in South  Dakota,  Wisconsin,  Michigan,
Kansas or  Oklahoma.  However,  certain  notice or similar  filings were made in
Kansas and Oklahoma.

     All necessary  approvals  associated with the Merger were obtained from the
Arizona  Commission  on March 1, 2000,  the Colorado  Commission on February 16,
2000, the Kansas  Commission on September 20, 1999, the North Dakota  Commission
on April 12, 2000,  the Oklahoma  Commission  on December 21, 1999,  the Wyoming
Commission  on March 13, 2000,  the Minnesota  Commission on June 12, 2000,  the
Texas Commission on May 30, 2000, and the New Mexico  Commission on May 4, 2000.
Copies of the orders  evidencing  these  approvals are filed on Exhibits  D-4.2,
D-5.2,  D-10,  D-3.2,  D-11,  D-7.2,  D-2.2,  D-8.2 and D-6.2 hereto. No further
approval  of these  commissions  or any other  state  commission  is expected or
required  in  connection  with the Merger.  As  indicated  above,  no filings or
approvals  pertaining  to the Merger were  necessary or were sought in Michigan,
South Dakota or Wisconsin.

     Set forth below is a summary of each of the state orders:

     In an order,  a copy of which is  attached  to the  Application  as Exhibit
D-2.2 ("Minnesota  Order"),  the Minnesota  Commission  approved the Merger, and
also approved certain settlement  agreements among NSP, the Minnesota Department
of Commerce,  the Minnesota Office of Attorney General and other  intervenors in
the state  proceeding.  Among other things,  the Minnesota  Order and settlement
agreements imposed certain conditions  regarding (1) a prospective electric rate
reduction to reflect  certain  non-fuel  Merger  savings;  (2)  pass-through  of
electric fuel,  purchased  power and purchased  natural gas savings;  (3) a rate
increase moratorium,  subject to certain conditions;  (4) quality of service and
reliability  standards;  (5)  access  to  records  and  reporting  requirements,
including  reports  on  generation  cost  unbundling,  the  viability  of retail
aggregation services, and strategies for mitigation of carbon dioxide emissions;
(6) certain commitments regarding state regulatory review of rate recoverability
of costs  allocated  to New NSP  Utility;  and (7)  commitments  to file  tariff
provisions to facilitate  distributed generation and customer "sale back" supply
services.  The Minnesota  Order includes a finding that retention by Xcel of the
natural gas distribution operations of NSP would serve the public interest.

     In an order,  a copy of which is  attached  to the  Application  as Exhibit
D-3.2 ("North Dakota Order"),  the North Dakota  Commission  approved the Merger
and a settlement  agreement between NSP and North Dakota Commission staff. Among
other things,  the North Dakota Order and settlement  agreement  imposed certain
conditions regarding (1) a prospective electric rate reduction; (2) filing of an
electric  performance  based regulation plan,  including  quality of service and
reliability  measures;  (3)  pass-through of electric fuel,  purchased power and
purchased  natural  gas  savings;  and (4)  access to  records  and  commitments
regarding state regulatory  review of rate  recoverability of costs allocated to
New NSP Utility.  The North Dakota  Order  includes a finding that  retention by
Xcel of the natural gas  distribution  operations  of NSP would serve the public
interest.

     In an order,  a copy of which is  attached  to the  Application  as Exhibit
D-4.2 ("Arizona Order"), the Arizona Commission approved the Merger. Among other
things,  the Arizona Order imposed  certain  conditions  regarding (1) access to
records and  commitments  regarding state  regulatory  review of non-fuel Merger
savings in a future BMG rate proceeding; and (2) certain reporting requirements.
The Arizona Order  includes a finding that  retention by Xcel of the natural gas
distribution operations of BMG would serve the public interest.

     In an order,  a copy of which is  attached  to the  Application  as Exhibit
D-5.2, the Colorado  Commission approved a stipulation and agreement among PSCo,
the staff of the Colorado  Commission,  the Colorado Office of Consumer Counsel,
and various other parties recommending approval of the merger subject to various
conditions.  Among other  things,  PSCo has  committed in this  stipulation  and
agreement to reduce retail rates, to file a combined  electric and gas rate case
in early 2002 with the expectation that new rates will go into effect on January
1, 2003, and to continue its existing  electric  earnings sharing  mechanism and
quality of service plans.  The Colorado  Commission  also approved a stipulation
and agreement among PSCo, the Colorado Office of Consumer  Counsel,  and various
other parties  addressing issues related to low income  customers.  Based on its
approval of these two  stipulations  and  agreements,  the  Colorado  Commission
approved the Merger.

     In an order,  a copy of which is  attached  to the  Application  as Exhibit
D-10, the Kansas Commission  approved an agreement among SPS, NSP, and the Staff
of the Kansas  Commission  setting  forth  various  commitments  relating to the
Merger, including an annual rate credit.

     In an order,  a copy of which is  attached  to the  Application  as Exhibit
D-6.2,  the New  Mexico  Commission  approved  the  Merger  subject  to  various
commitments  by SPS.  Among other  things,  SPS committed to credit or otherwise
reflect in rates merger savings by a guaranteed  amount to its New Mexico retail
customers  for a 54-month  transition  period and to hold its New Mexico  retail
customers  harmless from any and all negative  impacts of the Merger,  including
financial impacts.

     In an order,  a copy of which is  attached  to the  Application  as Exhibit
D-11,  the Oklahoma  Commission  approved a  stipulation  which  incorporated  a
regulatory plan relating to the Merger.

     In an order,  a copy of which is  attached  to the  Application  as Exhibit
D-8.2,  the Texas  Commission  found the Merger to be consistent with the public
interest subject to the conditions set out in a stipulation entered into by SPS,
the staff of the Texas Commission,  and certain other parties.  In summary,  the
stipulation  provides for the  implementation  of full retail customer choice by
SPS in its Texas retail service  territory  consistent with the  requirements of
Texas SB-7. As previously  discussed (see discussion in Item 3.C.1(b)(i)),  such
implementation  will require the future  divestiture of approximately  64-71% of
the generation  capacity owned by SPS and its affiliates in the SPS service area
region. Additionally,  the stipulation approved by the Texas Commission provides
for SPS to guarantee merger savings credits through December 31, 2005, to retain
its current  fuel  recovery  mechanism  to pass  through  fuel savings to retail
customers,  and to comply  with  various new  service  quality  and  reliability
standards.

     In an order,  a copy of which is  attached  to the  Application  as Exhibit
D-7.2,  the Wyoming  Commission  approved of the Merger based on the commitments
agreed to by Cheyenne in a stipulation  and agreement with the Wyoming  Consumer
Advocate  Staff.  Among other  things,  Cheyenne in this  stipulation  agreed to
various  measures to maintain its present  level of autonomous  and  independent
operations  after the merger and to an electric  and a gas base rate  moratorium
through January 1, 2004.

E.   Other

     The NSP and NCE Systems  possess  municipal  franchises  and  environmental
permits and licenses  that they may need to assign or replace as a result of the
Merger.  NSP  and  NCE  do  not  anticipate  any  difficulties   obtaining  such
assignments, renewals and replacements. In addition, British regulatory approval
may  also be  required  in  light  of  NCE's  ownership  interest  in  Yorkshire
Electricity and NSP's indirect investments in the United Kingdom.

     Except as set  forth  above,  no other  state or local  regulatory  body or
agency  and no other  Federal  commission  or agency has  jurisdiction  over the
transactions proposed herein.

     Finally,  pursuant to Rule 24 under the Act, the Applicants  represent that
the transactions proposed in this filing shall be carried out in accordance with
the  terms  and   conditions   of,   and  for  the   purposes   stated  in,  the
declaration-application no later than December 31, 2004.

Item 5.  Procedure

     The Commission is respectfully requested to publish, not later than January
31, 2000, the requisite  notice under Rule 23 with respect to the filing of this
Application-Declaration,  such notice to specify a date not later than  February
28,  2000,  by which  comments  must  have been  entered  and a date on or after
February  29,  2000,  as the date when an order of the  Commission  granting and
permitting this  Application-Declaration  to become  effective may be entered by
the Commission.

     It  is  submitted  that  a  recommended  decision  by a  hearing  or  other
responsible officer of the Commission is not needed for approval of the proposed
Merger.  The  SEC  Staff  may  assist  in the  preparation  of the  Commission's
decision.  There  should  be no  waiting  period  between  the  issuance  of the
Commission's order and the date on which it is to become effective.

Item 7.  Information as to Environmental Effects

     The Merger  neither  involves  "major federal  actions" nor  "significantly
[affects]  the  quality  of the human  environment"  as those  terms are used in
Section (2)(C) of the National  Environmental  Policy Act, 42 U.S.C.  Sec. 4332.
The only  federal  actions  related  to the Merger  pertain to the  Commission's
declaration  of the  effectiveness  of the  Joint  Registration  Statement,  the
approvals and actions  described  under Item 4 and  Commission  approval of this
Application-Declaration.  Consummation  of the Merger will not result in changes
in the  operations  of NSP,  NSP-W or NCE that  would  have  any  impact  on the
environment.  No federal agency is preparing an  environmental  impact statement
with respect to this matter.

          Annual revenues from the leases are approximately $2.7 million./29/ UE
          will attempt to renegotiate the terms of each of these leases so that,
          within five years after the date of consummation  of the merger,  each
          lease (and any other substation lease into which UE enters)  qualifies
          for  treatment as a capital lease under  general  accepted  accounting
          principles. If any lease cannot be so amended, UE proposes to transfer
          to SPS, and SPS proposes to acquire, at a price equal to then net book
          value,  the substation  that is the subject of the lease. In the event

                           NSP NON-UTILITY BUSINESSES

     The vast majority of NSP's non-utility  business are EWGs, FUCOs or QFs and
therefore would be exempt from the Act. A registered holding company may acquire
and hold an  interest  in an EWG and a FUCO  without  the  need to apply  for or
receive  approval  from  the  Commission.  ss.ss.32  and  33 of  the  Act.  (The
Commission  retains  jurisdiction  over certain related  transactions with prior
entities.) The  Commission has also  authorized the formation and financing of a
number of non-utility  subsidiaries of registered  holding companies in order to
invest in and hold  securities of QFs, FUCOs,  and EWGs.  See, e.g.,  Interstate
Energy  Corporation,   Holding  Co.  Act  Release  No.  27069  (Aug.  26,  1999)
(authorizing  intermediate  subsidiaries for holding EWGs,  FUCOs,  subsidiaries
whose  securities  are acquired under Rule 58, and ETCs);  Entergy  Corporation,
Holding Co. Act  Release No.  27039  (June 22,  1999)  (authorizing  development
activities,  providing management services to associate EWGs, QFs and FUCOs, and
providing  consulting and O&M services);  The Southern Company,  Holding Co. Act
Release No. 26212 (Dec. 30, 1994);  Entergy  Corp.,  Holding Co. Act Release No.
26322 (June 30, 1995);  Northeast  Utilities,  Holding Co. Act Release No. 25977
(Jan.   24,  1994)   (authorizing   Charter  Oak  Energy  and  COE   Development
Corporation):  Central and South West Corp.,  Holding Co. Act Release No.  26156
(Nov. 3, 1994) (authorizing CSW to form, acquire,  finance and own securities of
FUCOs);  Central and South West  Corporation,  Holding Co. Act Release No. 26155
(Nov. 2, 1994)  (authorizing  investment in joint venture which will  construct,
own and operate QFs and EWGs).

     A registered holding company may acquire "energy-related companies" meeting
the Rule 58 safe harbor conditions without the need for Commission approval.  17
C.F.R. ss. 250.58 (1999); Exemption of Acquisition by Registered  Public-Utility
Holding  Companies of Non-Utility  Companies  Engaged in Certain  Energy-Related
Activities, Holding Co. Act Release No. 26667 (Feb. 14, 1997). Under Rule 58, an
energy-related  company is a company that  derives or will derive  substantially
all of its revenues (exclusive of revenues from temporary  investments) from one
of the twelve  businesses  described in the Rule and from such other  activities
and  investments  as the  Commission may approve under Section 10. Rule 58 lists
the ownership of QFs as an  energy-related  activity under Rule  58(b)(1)(viii).
Almost all of NSP's and  certain of NCE's  non-utility  businesses  that are not
EWGs or FUCOs would be  energy-related  companies under the Commission's Rule 58
or prior Commission precedent.

     The non-utility subsidiary companies are further described below in tabular
form,  followed by a textual  description of the larger  non-utility  subsidiary
businesses.

     connection with, affordable multi-family housing properties").

                                    Annex D-2
             SUPPLEMENTAL DESCRIPTION OF NSP NON-UTILITY BUSINESSES

     NSP and  NSP-W  engage  directly  and  indirectly  in  various  non-utility
activities.  NSP  directly  provides:  (i) an  appliance  services  program  for
residential  customers;   (ii)  construction  and  maintenance  of  natural  gas
distribution  systems for third parties  (primarily  end-users and municipal gas
systems);  (iii)  sale  of  steam  to  industrial  customers  in  NSP's  service
territory;   (iv)   installation   and   maintenance  of  street   lighting  for
municipalities;  (v)  propane  services;  (vi)  fuel  oil  services;  and  (vii)
installation and maintenance of distributed generation on customer's facilities.

     In addition,  NSP owns directly the interests of the following  non-utility
subsidiary companies:  Viking Gas Transmission Company ("Viking"), an interstate
natural gas  pipeline  subject to FERC  jurisdiction  under the NGA; NRG Energy,
Inc.  ("NRG"),  a  holding  company  for many of NSP's  non-utility  businesses,
including  significant  investments  in  independent  power projects and foreign
operations;  Energy Masters  International,  Inc.  ("EMI"),  an energy  services
company;  Seren  Innovations,  Inc.  ("Seren"),  a company that provides  cable,
telephone and high-speed internet access system; Ultra Power Technologies,  Inc.
("Ultra  Power"),  a company  currently in the process of winding up its affairs
and  formerly in the  business of  marketing  power  cable  testing  technology;
Eloigne Company ("Eloigne"), an investor in projects that qualify for low-income
housing tax credits;  NSP Financing I, a special purpose  business trust;  First
Midwest Auto Park, Inc.  ("FMAP"),  the owner of a parking garage;  United Power
and Land Company  ("UP&L"),  a real estate  investment  company;  Reddy Kilowatt
Corporation  ("Reddy  Kilowatt"),  the owner of  certain  intellectual  property
rights;  Natrogas,  Inc. ("Natrogas"),  a provider of propane services;  Nuclear
Management  Company  ("NMC"),  a limited  liability  company  that will  provide
services to the nuclear operations of its members;  and NSP Nuclear Corporation,
a subsidiary  formed to hold NSP's  interest in the NMC. NSP owns 100% of all of
the foregoing  businesses,  except that NSP owns 25% of the membership interests
in NMC and as a result of the  issuance  of equity by NRG  currently  has an 84%
ownership interest in NRG.

     NSP-W owns  directly  all of the  outstanding  common  stock of  Clearwater
Investments,  Inc. ("Clearwater"),  an investor in housing projects that qualify
for low-income  housing tax credits,  and NSP Lands, Inc. ("NSP Lands"),  a real
estate  investment  company.  NSP-W also owns  75.86% of Chippewa  and  Flambeau
Improvement  Company  ("C&F"),  a company  that  builds  and  operates  dams and
reservoirs for hydro-electric plants.

     All of these non-utility activities are substantially similar to activities
approved by the Commission in the past. Set forth below is a description of each
of these  activities  along with  authority  cited in the footnotes that support
retention of these  non-utility  activities.  At December 31, 1999 and March 31,
2000,  NSP's aggregate  investment in its non-utility  subsidiaries  constituted
less than 44 percent of its common stock equity.

A.   Direct Activities of NSP

     1.  Appliance  Warranty  and Repair  Services:  NSP  provides an  appliance
warranty and repair program for residential  customers  (known as "NSP Advantage
Service").  The service is similar to that offered by many other electric and/or
gas  utilities  in the  region.  Appliances  covered  include  heating  and  air
conditioning  systems,  water heaters,  refrigerators,  dishwashers  and clothes
washers./125/

     2.  Construction  of Gas Pipelines:  NSP directly  constructs and maintains
natural gas  distribution  systems for third  parties,  primarily  end-users and
municipal gas systems,  that either want installation of new natural gas systems
or want to expand  the  capacity  or number of sources  from which they  receive
natural gas./126/

     3. Production and  Distribution of Steam:  NSP supplies steam to commercial
and industrial customers, which is obtained from NSP's generating stations./127/

     4. Installation and Maintenance of Street Lighting for  Municipalities  and
Other  Customers:  NSP installs and maintains  street  lighting for more than 50
municipalities  throughout its service territory in Minnesota,  North Dakota and
South  Dakota./128/  This  service  consists  of  replacing  the light bulbs and
maintaining the light fixtures.

     5. Propane Services: NSP owns and operates approximately 13 million gallons
of propane storage  capacity  (above ground tanks)  installed for the purpose of
meeting the peak day and winter  season  natural gas supply  needs of its retail
gas  customers./129/  Other  natural gas  utilities in the NSP region  similarly
operate  propane-air storage and injection  facilities.  (In controlled volumes,
propane  can be mixed with air to  vaporize  the liquid  propane,  and the vapor
mixture is injected  into the natural gas  distribution  system as a replacement
for pipeline natural gas.) When propane storage capacity or supplies will not be
needed to meet retail  customer supply needs,  NSP leases limited  quantities of
the storage  capacity  for a fee or may sell  unused  propane  supplies./130/  A
representative  level of the propane  storage or sale revenues is reflected when
setting NSP's regulated natural gas rates.

---------------
125  Rule  58(b)(1)(iv);  see also Mississippi Power and Light Company,  Release
     No.  35-25140  (August 30,  1990) (a  subsidiary  of a  registered  holding
     company allowed to create a "Space Conditioning Program" to market and sell
     "manufacturer's  warranties  or  other  maintenance  agreements  for  space
     conditioning  equipment  such as water  heaters  and heat pumps and related
     weatherization, ductwork and wiring improvements").
126  Construction  of gas  pipelines  for third parties was approved in National
     Fuel Gas  Company,  Release  No.  35-24381  (May 1,  1987),  in  which  the
     Commission  authorized  Utility  Constructors,  Inc.,  a  subsidiary  of  a
     registered   holding  company,   to  provide  "pipeline   construction  and
     replacement...and  related and auxiliary  services" to subsidiaries  and to
     non-associate companies; Rule 58(b)(1)(vii).
127  Rule  58(b)(1)(vi);  see also CINergy  Corp.  et al,  Release No.  35-26474
     (February 20, 1996)  (Commission  authorized the  establishment  of two new
     subsidiaries  to engage in district  heating and cooling  businesses.  Such
     businesses  will deliver  chilled and/or heated water and possibly steam to
     customers  for  heating  and cooling  purposes  and supply  such  customers
     related  services);  The  Southern  Company  et al,  Release  No.  35-26468
     (February 2, 1996) (Commission granted SEI Holdings,  Inc. ("Holdings"),  a
     new holding company that will hold  investments in EWGs,  FUCOs,  companies
     that invest in EWGs and FUCOs, and companies that provide functions related
     to the operation of EWGs and FUCOs, authority to acquire an interest in, or
     the  securities  of,  one or more  companies  that  derive  or will  derive
     substantially  all of its  revenues  from the  production,  conversion  and
     distribution of steam);  General Public Utility Corp., 32 SEC 807,  840-841
     (1951)  (Commission  authorized  retention of steam heating systems.  Steam
     from such  systems was used to generate  electricity  and sold to customers
     for heating purposes.); In re The North American Company, 11 SEC 194 (April
     14, 1942)  (Commission  authorized  retention of steam  heating  operations
     which  provided  steam heat to customers and was used in the  generation of
     electricity);  WPL Holdings, Inc., Holding Co. Act Release No. 26856 (April
     14,  1998)  (delivery  of steam to more than 200  residential  and business
     customers.
128  Rule 58(b)(1)(vii).
129  Scana Corporation, Holding Co. Act Release No. 27133 (Feb. 9, 2000).
130  As described  in Annex E, NSP entered  into short term propane  storage and
     sale  agreements  with  its  affiliate   Natrogas  in  February  2000.  The
     agreements expire in 2000. The agreements are pending Minnesota  Commission
     approval in Docket No. G002/AI-00-258. The Minnesota Department of Commerce
     has recommended approval of the agreements.

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

     In addition,  Black Mountain Gas Company (BMG) provides propane services at
retail in Page, Arizona through its Page Division.  BMG's retail propane service
rates are regulated by the Arizona Commission.

     6. Fuel Oil  Services:  NSP owns and  operates  fuel oil  storage  capacity
(above ground tanks) at its Inver Hills electric  generating plant in Minnesota.
The fuel oil storage was installed during the oil shortages in the 1970s for the
purpose of storing fuel  inventory so the Inver Hills plant could be operated to
meet the peak day electric service needs of NSP's retail and wholesale  electric
customers.  In 1998,  the Inver Hills plant was  converted to use natural gas as
its  primary  fuel,  with fuel oil as a  back-up  fuel.  When  fuel oil  storage
capacity or supplies  will not be needed to meet  electric  customer  generation
needs,  NSP leases limited  quantities of the storage  capacity for a fee or may
sell unused fuel oil supplies.

     7. Distributed  Generation  Services:  NSP has just recently begun to offer
installation  and  maintenance  services on the  customer  side of the meter for
distributed  generation services.  The service is quite similar to the appliance
sale and repair service except that it is focused on providing  customers  these
maintenance services on distributed  generation equipment purchased and operated
by the customer./131/

B.   Subsidiaries of NSP

     1.  Viking owns and  operates a 500 mile  interstate  natural gas  pipeline
serving  portions of  Minnesota,  Wisconsin  and North Dakota with a capacity of
approximately  550,000 Mcf per day.  Viking is a  regulated  natural gas company
under the Natural Gas Act of 1938,  as amended (the  "Natural Gas Act").  Viking
currently  operates  exclusively as a transporter of natural gas for third-party
shippers under FERC rate and tariff jurisdiction.  The Viking pipeline currently
transports  natural  gas for the gas  utility  operations  of NSP and  NSP-W and
provides  gas  transportation   services  for  numerous  other   customers./132/
Approximately 75% of NSP's and NSP-W's gas customers are located within 40 miles
of the Viking pipeline. However,  approximately 83% of Viking's firm capacity is
held by non-affiliates.

     2. FMAP,  UP&L and NSP Lands are engaged in various forms of land ownership
associated with NSP's and NSP-W's utility  operations.  FMAP owns and operates a
parking garage.  NSP leases from FMAP 92 parking spaces as well as 14,000 square
feet of unimproved  storage  space on the first and second floor.  The garage is
located  next to NSP's  corporate  headquarters,  and is  primarily  used by NSP
employees.   It  provides  secure,  close  parking  for  NSP  employees.  It  is
anticipated  that, in the event that additional  facilities at NSP  headquarters
are  necessary,  the parking  garage will be razed and the site will be used for
such  expansion.  UP&L's land  holdings  include the  Renaissance  Square office
facility directly adjacent to NSP's corporate  headquarters,  which NSP uses for
utility  business.  NSP has long-term  agreements to lease  virtually all of the
Renaissance Square facility./133/

---------------
131  Rule 58(b)(1)(iv).
132  New Century  Energies,  Inc.,  Holding Co. Act Release No.  26748 (Aug.  1,
     1997) (allowing  retention of interstate  pipeline that provided service to
     PSCo, Cheyenne and others); CNG Transmission Corp., Holding Co. Act Release
     No. 25239 (Jan.  9, 1991);  Central and  SouthWest  Corp.,  Holding Co. Act
     Release No. 14555 (Dec. 28, 1961).
133  In previous orders, the Commission has approved the purchase of real estate
     which is  incidentally  related to the  operations of a registered  holding
     company.  See American  Electric  Power Service Co.,  Release No.  35-19981
     (April 12,  1977)  (Commission  allowed a subsidiary  of American  Electric
     Power to purchase  employees' homes in conjunction with their transfer to a
     new  position  in  a  different  geographical  area.)  Furthermore,  FMAP's
     ownership  of a parking  garage and NSP's lease of the  Renaissance  Square
     facility can be  distinguished  from  ownership  of a  commercial  building
     brought  into  question  in In re The North  American  Company,  11 SEC 194
     (April 14, 1942). In North American,  a registered  holding company owned a
     twenty-five floor office building in downtown New York.  However,  only two
     whole  floors  and  part of  three  other  floors  were  occupied  by North
     American,  and the building was not within close proximity to the company's
     headquarters.   Given  the  proximity  of  the  parking   garage  to  NSP's
     headquarters,  the benefits to employees  it  currently  provides,  and its
     potential for future use,  ownership of the garage is reasonably  necessary
     to the operation of the utility business. Similarly, since virtually all of
     the Renaissance  Square facility is used by NSP in its utility  operations,
     UP&L  should be  allowed  to  retain  its  interest  in the  facility.  The
     Minnesota  Commission has approved both the NSP/FMAP lease and the NSP/UP&L
     lease.

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

     Besides  Renaissance  Square,  UP&L owns and holds additional real property
typically  surrounding  or  adjacent  to  property  owned and used by NSP in its
regulated operations.  The majority of UP&L's land consists of property adjacent
to land owned and used for NSP's Sherco and Monticello generating stations. UP&L
receives  rental revenue for some of the land,  which is leased to third parties
for agricultural purposes.  UP&L provides a direct benefit to NSP. Real property
needed by NSP for its utility  operations  can often only be obtained as part of
purchases  of larger  tracts.  In these  cases,  UP&L may acquire the  property,
transfer the useful portion to NSP, hold any potential useful portion for future
use by NSP, and resell the  remainder.  Since UP&L is not subject to NSP's first
mortgage indenture,  it is easier to transfer real property through UP&L than to
obtain a separate release from the mortgagee for each transaction./134/

     NSP Lands was created in 1992 to enable NSP-W to sell excess land  adjacent
to NSP-W's hydro reservoirs.  Since the time of its creation, NSP Lands' primary
focus has been to liquidate  NSP-W's  unused land adjacent to Lake Arbutus,  the
hydro reservoir at NSP-W's Hatfield hydro project./135/

     3. EMI  provides  value-added  energy  conservation  and energy  management
services to retail  customers,  both inside  NSP's  service  territory  and on a
national basis through offices in fifteen  states./136/  Programs offered by EMI
include:  (i)  installation  of more  efficient  lighting  systems;  (ii)  group
relamping (systematic  replacement of lamps before they burn out and cleaning of
lens, reflective surfaces and fixtures);  (iii) consolidated billing service and
auditing of utility bills;  (iv) performance  contracting  whereby EMI evaluates
facilities and identifies energy-efficiency  improvement opportunities;  and (v)
identification  of water  conservation  opportunities.  EMI is also a party to a
joint venture with Energy Performance Services of King of Prussia, Pennsylvania,
to provide energy  savings  performance  services to the U.S.  Department of the
Army, Corps of Engineers. (Contract No. DACA87-97 D0073).

---------------
134  In UNITIL  Corporation et al, Release No.  35-25524  (April 24, 1992),  the
     Commission  noted that  UNITIL  Realty  Corporation,  a  subsidiary  of the
     registered holding company,  UNITIL,  which acquired real estate to support
     utility operations, engaged in activities which were within the confines of
     the Act.  UP&L's  ownership of land  adjacent to the Sherco and  Monticello
     plant sites are  necessary to support such plants'  future  operations.  As
     stated  previously,  the land held by NSP Lands surrounded a hydro-electric
     generation  facility  previously  owned by NSP-W and is in the  process  of
     being sold. Consequently,  as the real estate held by UP&L and NSP Lands is
     substantially  similar to that  owned by UNITIL  Realty  Corporation,  UP&L
     Lands should be allowed to retain their interests in such property.

     26401 (Oct. 27, 1995); Central and South West Corporation,  Holding Co. Act
     Release No. 26367 (Sept. 1, 1995).

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

     4. Seren provides cable  television,  high-speed cable internet,  and local
and long  distance  telephone  service./137/  Seren has  applied  to the FCC for

                               AFFILIATE CONTRACTS


SALE OF FUEL FOR ELECTRIC GENERATION


     NRG  Energy  Center  Washco  LLC has the  option  to sell  wood  by-product
purchased  from  Andersen  Corporation  to NSP for  use as  fuel  in  generating
facilities.  The price for the wood by-product equals the average cost per MMBtu
of solid fuel delivered to a NSP generating  plant during the calendar year and,
as a result such price is in compliance  with Rule 90(d)(2) and Rule 92(b) under
the 1935 Act.  This  contract  was  approved  by the  Minnesota  Public  Utility
Commission ("MPUC") in Docket No. E002/M-86-775.

     NSP purchases  refuse-derived  fuel ("RDF") from NRG's Newport facility and
Elk River Facility through a series of contracts,  including a lease of land, an
operating  agreement,  and a  reimbursement  agreement for additional  pollution
control  equipment  installed  by NSP to burn RDF.  In NSP's  view,  the  proper
characterization of the transaction is the sale by NRG of a good manufactured by
it (i.e., RDF), and the price being paid is in compliance with Rule 90(d)(2) and
Rule  92(b)  under the 1935 Act.  The  various  contracts  associated  with this
transaction   were   approved  by  the  MPUC  in  Docket  Nos.   E002/AI-93-821,
E002/AI-94-950, E002/AI-93-770, and E002/AI-95-171.

URANIUM FUEL ENRICHMENT SERVICES

     Louisiana Energy Services ("LES") is a joint venture which was to operate a
nuclear enrichment  facility in Louisiana.  NSP's wholly owned subsidiary,  NRG,
owns  100%  of  Graystone  Corporation  (Graystone),   an  investor  in  uranium
enrichment services. Graystone is a general partner in the LES venture, and also
owns LePaz Inc.,  which is a limited  partner in LES.  Together,  Graystone  and
LePaz own 6.74% of LES.

     Under the terms of the contract,  LES was to supply 30% of NSP's enrichment
services  needs for the period  October 1, 1995 through  September 30, 2005. The
agreement  contained a term specifying that if LES could not perform,  NSP would
purchase equivalent amounts from Urenco, which is not affiliated with NSP but is
the main investor in LES. Pursuant to this provision,  NSP has purchased between
$7 million and $8 million in enrichment services  from Urenco,  as LES has never
performed  under  the  agreement.  NSP and LES have  agreed  to  terminate  this
arrangement  on December  31, 2000,  and, in the interim,  NSP will not make any
purchases from LES. As a result, this transaction will not involve the sale of a
good or service for a charge.  The remainder of NSP's enrichment  services needs
are  purchased  on the spot  market.  This  contract was approved by the MPUC in
Docket No. E002/AI-92-1164.

SALE OF STEAM

     NSP sells cold steam to NRG Energy  Center Washco LLC (a subsidiary of NRG)
from its  King  plant.  The  steam  is then  reheated  and  resold  to  Andersen
Corporation  and a  Minnesota  correctional  facility.  NRG  pays  approximately
$700,000 per year for the steam, which is NSP's incremental cost of producing an
equivalent  amount of electricity  (measured in BTUs) with the cold steam.  As a
result,  such price is in compliance with Rule 90(d)(2) and Rule 92(b) under the
Act.  Alternatively,  the sale of steam is conceivably  exempt under Rule 81. In
addition,  NRG pays  approximately  $450,000 per year for NSP to operate the NRG
boiler  facilities  based on NSP's fully allocated cost plus a small  management
fee (5%) required to reflect potential  unaccounted-for overhead costs for state
regulatory purposes to avoid subsidization. NSP believes that such pricing is in
compliance  with Rules 90 and 91 under the 1935 Act.  This contract was approved
by the MPUC in Docket No. E002/M-86-775.

     NSP maintains and operates NSP's  Highbridge  Units 3 and 4 boilers for NRG
Energy Center  Rock-Tenn,  a subsidiary of NRG, so that NRG can produce steam to
sell to  RockTenn  Corporation.  NRG pays  approximately  $3 million per year at
NSP's fully  allocated cost,  which includes a small  management fee required to
reflect the potential for  unaccounted-for  overhead costs for state  regulatory
purposes to avoid  subsidization.  NSP believes that such price is in compliance
with Rules 90 and 91 under the 1935 Act.  This contract was approved by the MPUC
in Docket No. E002/CI-82-523.

GAS SUPERVISORY CONTROL AND DATA ACQUISITION AND DISPATCHING SERVICES

     NSP supplies NSP-W and Viking with supervisory control and data acquisition
("SCADA") services for their gas businesses  pursuant to separate contracts with
Viking and NSP-W.  NSP also supplies NSP-W gas  dispatching  and other services.
NSP-W pays  approximately  $192,000 per year,  while  Viking pays  approximately
$256,000  per year.  Both  contracts  were  approved  by the MPUC in Docket  No.
G002/AI-94-831,  and the contract between NSP and NSP-W was approved by the PSCW
in Docket No. 4220-AU-117. A SCADA system electronically  communicates gas flow,
gas  pressure,  and gas  equipment  set point data for the  delivery  system and
records  the data in a  computerized  data  storage  system for  monitoring  and
control purposes.  Gas dispatching includes monitoring and controlling the flow,
pressures and operating  conditions of a natural gas delivery system through the
use of a SCADA system.  The agreements enable NSP, NSP-W and Viking to share the
costs of a single  system  rather than each owning and operating a SCADA system.
The  three  companies  are each  allocated  and  billed  a share  of the  actual
operating  costs  incurred  by NSP on a  monthly  basis  based on the  number of
metering  points  monitored  for each  company.  NSP believes  that such pricing
complies with Rules 90 and 91.

MANAGEMENT OR LEASING OF LAND OR OTHER FACILITIES

     NSP manages the Renaissance  Square Office Building for United Power & Land
("UP&L").  NSP  provides  this  service in exchange  for two percent (2%) of the
building's  gross annual rents.  All direct costs of  management  are charged to
UP&L  under  an  administrative   services  agreement.   These  typically  total
approximately  $1.1 million per year.  NSP believes  that such pricing  complies
with  Rules 90 and 91.  This  contract  was  approved  by the MPUC in Docket No.
E002/AI-94-1188.

     UP&L leases  office space on floors two through  eleven of the  Renaissance
Square office building to NSP. NSP pays UP&L rent based on a square footage rate
of approximately $3.6 million per year, consisting of a base rental fee on a per
square  foot basis and a  separate  fee for NSP's  share of the actual  costs of
operating and maintaining  the building.  These terms were more favorable to NSP
than other bids that NSP received and result in a situation equivalent to if NSP
owned the building, as the UP&L target return in establishing the lease payments
was NSP's regulated return on equity.  This contract was approved by the MPUC in
Docket No. E002/AI-90-845.  UP&L also leases office space on the first floor and
in the basement of the Renaissance  Square office building to NSP. This contract
was approved by the MPUC in Docket No.  E002/AI-94-1056.  NSP believes  that its
rental payments to UP&L comply with Rules 90 and 91 under the Act.

     First  Midwest Auto Park  ("FMAP")  leases 14,000 square feet of unimproved
storage  area to NSP in the  first  and  second  floors  of the  parking  garage
directly  adjacent to NSP's  headquarters for  approximately  $100,000 per year.
This contract was approved by the MPUC in Docket No. E002/AI-94-1043.  FMAP also
leases 92 parking  spaces in the  parking  facility  to NSP at an annual rent of
approximately $220,00 per year. This contract was approved by the MPUC in Docket
No. E002/AI-94-1042. NSP believes that the payments to FMAP comply with Rules 90
and 91 under the Act.

     Seren  Innovations,  Inc.  ("Seren"),  a wholly  owned  subsidiary  of NSP,
entered  into a lease  agreement  with NSP that allows  Seren to attach cable or
similar  telecommunications  facilities to NSP's distribution  poles,  conduits,
ducts and other  properties.  The lease is  effective  February 20, 1998 through
December  31,  2018,  and is  applicable  in  Minnesota,  South Dakota and North
Dakota.  NSP receives  approximately  $425,000 per year in lease  payments  from
Seren,  calculated  pursuant to a formula rate outlined by the FCC. As a result,
NSP believes that such  transaction  is exempt under Rule 81 or is determined in
compliance with Rules 90 and 91 under the Act. This contract was approved by the
MPUC in  Docket No.  E002/AI-98-377.  Under  the federal  Telecommunications Act
