NORTHERN  STATES  POWER  COMPANY  (WISCONSIN)


NOTES  TO  FINANCIAL  STATEMENTS
- --------------------------------

     Northern States Power Company, a Wisconsin corporation (NSP-Wisconsin) is a
wholly  owned  subsidiary  of   Northern  States  Power  Company,   a  Minnesota
corporation (NSP-Minnesota).  The term NSP refers to NSP-Wisconsin combined with
NSP-Minnesota  and  its  other  subsidiaries.

     In  the  opinion  of  management,   the  accompanying  unaudited  financial
statements  contain  all  adjustments  necessary to present fairly the financial
position of  NSP-Wisconsin as of June 30, 2000 and Dec. 31, 1999, the results of
its  operations for the three months and six months ended June 30, 2000 and 1999
and  its cash flows for the six months ended June 30, 2000 and 1999.  Due to the
seasonality  of  NSP-Wisconsin's  electric and gas sales, operating results on a
quarterly  and  year-to-date  basis are not necessarily an appropriate base from
which  to  project  annual  results.

     The  accounting  policies followed by NSP-Wisconsin are set forth in Note 1
to  NSP-Wisconsin's  financial  statements in its Annual Report on Form 10-K for
the  year  ended  Dec.  31, 1999 (1999 Form 10-K). The following notes should be
read  in  conjunction with such policies and other disclosures in the Form 10-K.

1.      BUSINESS  DEVELOPMENTS
- ------------------------------

     PROPOSED  MERGER  -  On  March  24, 1999 NSP and New Century Energies, Inc.
(NCE),  a  utility  based in Denver, Colo., agreed to merge. It is expected that
NSP-Wisconsin  will  continue  to exist as an operating subsidiary of the merged
company.    Final  regulatory approval is expected in the third quarter of 2000.

     COMMON  STOCK  EQUITY  -  In March 2000, NSP-Wisconsin filed an application
with the Public Service Commission of Wisconsin (PSCW) to sell up to $30 million
of  its  common  stock  to its parent company, NSP-Minnesota. The PSCW issued an
order  authorizing  the  sale  on  April  25.  On May 15, 2000, 71,000 shares of
common  stock  were  issued  for approximately $30 million to NSP-Minnesota. The
proceeds  were  used  to  repay  short-term  debt.

     LONG TERM DEBT - In 1999 NSP-Wisconsin received approval to issue up to $80
million  of  long-term debt, which is now scheduled to be issued during the last
half  of  2000.    The proceeds will be used primarily to repay short-term debt.

     NEW  CUSTOMER  -  In 2000, NSP-Wisconsin was selected to supply electricity
and  operate  the  distribution  system  at Fort McCoy, a regional Army training
center  near  Sparta, Wis. In May 1997 NSP-Wisconsin was selected to operate the
natural gas system at Fort McCoy.  Fort McCoy is a training center for more than
120,000  reserve  and  active  military  personnel.    There are more than 1,000
buildings on 60,000 acres.  NSP-Wisconsin will begin providing service under the
new  contract  in  the  fall  of  2000.

     WHEATON PLANT CONVERSION - In 2000 NSP-Wisconsin converted units 1 and 3 of
the Wheaton generating plant to operate on both oil and natural gas.  Previously
the  units  operated  on  oil  exclusively.    Two  other  units at Wheaton were
converted  in 1997.  The conversions were prompted by an opportunity to decrease
the  cost  of  producing  electricity  and  reduce  plant  emissions.

2. REGULATION  AND  RATE  MATTERS
- ---------------------------------

     ELECTRIC  TRANSMISSION In April 1998, Wisconsin state legislators enacted a
law  which  includes  provisions that require the PSCW to order a public utility
that  owns  transmission  facilities  in  Wisconsin  to  transfer control of its
transmission  facilities  to an ISO (an independent nonprofit organization which
will  operate,  but  not  own,  an  electric  transmission system) or divest its
interest  in  its transmission facilities to an Independent Transmission Company
or  ITC  (an  independent  organization  that  would own and operate an electric
transmission  system)  if the public utility has not already transferred control
to  an  ISO  or divested to an ITC by June 30, 2000.  NSP joined the Midwest ISO
(MISO) in late 1999 and filed for PSCW and FERC approval in March 2000. The MISO
is  not  expected  to be operational until Nov. 1, 2001.  Therefore, on June 30,
2000 the PSCW issued an order that effectively waived the June 30, 2000 deadline
for  the state's five major utilities to relinquish transmission system control.
In  its  order,  the  PSCW stated that "such a waiver is reasonable" because the
five  utilities  had  already filed applications with the FERC to join the MISO,
and  that "further performance on their part is impossible". It is expected that
the  PSCW  will approve NSP-Wisconsin's request to transfer operating control of
its  transmission system to the MISO and certify that joining the MISO meets the
statutory  requirement  for a separate transmission operating structure once the
MISO  becomes  operational.

     Also  in  support  of a separate transmission operating structure, in March
the  PSCW held hearings in a proceeding aimed at developing a uniform definition
of  transmission  facilities.  NSP-Wisconsin and other Wisconsin utilities filed
testimony  supporting their positions. On July 14, 2000 the PSCW issued an order
on  classification  of  transmission  facilities.   The order is consistent with
NSP-Wisconsin's  proposal  to classify all facilities at or above 69 kv, and its
34.5  kv  facilities  in  northern  Wisconsin,  as  transmission.

     CONSTRUCTION  AUTHORIZATION -  In 1996, NSP and Dairyland Power Cooperative
(DPC)  of  LaCrosse,  Wis.  proposed  building  an  electric transmission system
between NSP-Minnesota's Chisago County substation in eastern Minnesota and DPC's
Apple  River  substation  in  northwestern  Wisconsin  in response to a need for
additional  reliability and capacity in both regions.  During the second quarter
of  1999,  the  PSCW  granted  permission  to build the Wisconsin portion of the
system.    The  City  of  St.  Croix  Falls. Wis. and the Concerned River Valley
Citizens  advocacy  group  (the  "parties")  filed  lawsuits  against  the  PSCW
appealing the decision.  Approval from the Minnesota Environmental Quality Board
(MEQB)  was  delayed  to  address additional discovery by the parties.  In early
2000, NSP and DPC agreed with the parties to enter into mediation. The mediation
was  coordinated  by  a  mediator  from the Office of Administrative Hearings in
Minneapolis, Minn.  A preliminary agreement by the parties from this process was
released  in June.  A formal, non-binding agreement is currently being finalized
and  the  Wisconsin  lawsuit is expected to be withdrawn in the third quarter of
2000.   The federal lawsuit was withdrawn by the City of St. Croix Falls without
prejudice  in June.  Once the final agreement is signed, an alternative solution
to  the  original  filing  would  be  pursued.    This will include a new 115 kv
transmission  line  between  the  Chisago  County substation and the Apple River
substation.    Parts  of  the  line would be placed underground in the cities of
Taylors Falls and St.Croix Falls, while the crossing of the St.Croix River would
be  placed  overhead.    Routing  and permitting activities would be required in
Minnesota  in  order  to acquire conditional use permits and an amendment of the
PSCW  order  would  be  requested  in  Wisconsin.

     TEMPORARY  FUEL  COST  SURCHARGE - On Feb. 14, 2000, NSP-Wisconsin filed an
application  with  the  PSCW  to  increase  electric  rates for fuel costs. This
application  was  subsequently  updated with additional information on March 17,
2000.  The increase is primarily the result of higher purchased power costs than
were  anticipated  in  base  rates. The surcharge factor is expected to increase
revenues  by  approximately  $6.5  million  in  2000  and  represents an average
increase  for  all  customer  classes  of  approximately three percent. The PSCW
issued  their  order granting the surcharge on May 2, 2000. The surcharge factor
is  expected  to  be  effective  through  Dec.  31,  2001.

      RELIABILITY  2000  -  During the summer of 1999, Wisconsin state lawmakers
passed  "Reliability 2000" legislation which included steps necessary to further
progress  toward a restructured industry, including allowing retail customers to
choose  their  electric  supplier.    One  of  the provisions of the legislation
establishes  a  "public  benefits"  fund,  to  be  administered  by the State of
Wisconsin,    which will use money collected from Wisconsin utilities' customers
to  pay  for  low-income assistance, conservation programs, and renewable energy
and  environmental  research  programs.   This fund will increase the  amount of
money  that  must be collected from NSP-Wisconsin's customers. It is anticipated
that  NSP-Wisconsin  will  begin  collecting  a  surcharge  from  its  Wisconsin
customers  in  September  2000.

     PLANT  DEPRECIATION  - In June 2000 NSP-Wisconsin filed an application with
the  PSCW  for  approval  of changes to certain depreciation practices.  In July
2000  a  similar  filing  was  made  with the FERC.  NSP-Wisconsin expects their
decisions  before  the  end  of  2000.  The proposed changes are not expected to
change  the  annual  depreciation  expense  for  2000  or  2001.

     MICHIGAN RESTRUCTURING - On June 3, 2000 Michigan's Governor Engler  signed
Act  141,  the "Customer Choice and  Electric Reliability Act",  into law.   The
passage of  Act 141 means there  will be customer choice  for all  customers  in
Michigan, including NSP-Wisconsin's customers in the Upper Penninsula,  starting
Jan. 1, 2002.   Key elements of  the law that  may affect NSP-Wisconsin  and its
approximately 10,000 electric customers include developing reliability standards
and fuel disclosure standards,  Codes of Conduct,  a State-wide Customer  Choice
Education  Program and an  Upper Penninsula Market  Power Study.   Act 141  also
contains a  number of consumer protection  provisions  dealing with  "cramming",
"slamming",  and low income energy assistance.   Utilities are required to  file
utility-specific restructuring plans in  October of 2000 and unbundled rates  by
June of 2001. The five percent rate reduction and rate freeze ordered in Act 141
does not  apply to  NSP-Wisconsin  or other utiities  with less than   1,000,000
customers in Michigan.

3. COMMITMENTS  AND  CONTINGENT  LIABILITIES
- --------------------------------------------

     LEGAL  CONTINGENCIES  -  In the normal course of business, various lawsuits
and  claims  have arisen against NSP.  Management, after consultation with legal
counsel,  has  recorded  an estimate of the probable cost of settlement or other
disposition  of  these  matters.

     As  discussed in Item 3 of NSP-Wisconsin's 1999 Form 10-K, On Feb. 20, 1999
a  person  who was not an NSP employee was killed while working with a hydraulic
press  at  NSP-Wisconsin's  Western  Avenue Service Center. A claim filed by the
decedent's  family  was  fully  resolved  during  the  first  quarter  of  2000.

     ENVIRONMENTAL  CONTINGENCIES  -  As  discussed  in  Note 8 to the Financial
Statements  in  the 1999 Form 10-K, NSP-Wisconsin had been named as one of three
potentially  responsible  parties in connection with environmental contamination
at  a  site in Ashland, Wis. As discussed below, the United States Environmental
Protection  Agency  (EPA)  and  Wisconsin Department of Natural Resources (WDNR)
continues  to  evaluate  proposed  methods  of  remediating  the  contamination.

     The  Ashland  site  has  been  evaluated using the Hazardous Ranking System
under  the Comprehensive Environmental Response, Compensation and Liability Act.
Preliminary  results  indicate  that the Ashland site is likely to be named as a
Superfund  site.    The  EPA has requested that the Governor of Wisconsin concur
with  this  assessment.    Being  named  as  a  Superfund site will increase the
administrative  and  transaction  costs  of  the  cleanup  project.

     The  EPA  and  WDNR  approved   NSP-Wisconsin's  proposal  for  an  interim
groundwater  treatment  system  for  the   portion  of  the  Ashland  site  that
NSP-Wisconsin  owns.  The system is under construction and should be complete by
September  2000.    The  estimated  cost  to  build  the  system  is  $325,000.

     In  March  2000  NSP-Wisconsin  received  two  formal data requests for its
Wheaton  and  French  Island  generating  facilities  from the EPA under Section
114(a)  of  the  Clean  Air  Act.  For  the Wheaton facility  the  data  request
focuses on  fuel usage, operating hours, operating loads and stack test data for
the time period Jan. 1, 1999 to present. It was during this time period that two
units  at  Wheaton  had failed  stack tests  for particulate  matter and  carbon
monoxide (Unit 2) and particulate matter (Unit 4) when firing  oil  at low load.
The WDNR issued a Notice of Violation  (NOV) letter to NSP-Wisconsin for each of
these incidents.  The two units were retested later  in 1999 and found to be  in
compliance. The NOV's were formally closed out by DNR  in  early  January  2000.
Data requests of this type from the EPA under Section 114(a) of  the  Clean  Air
Act are sometimes used in anticipation of a potential  enforcement  action.

     The   second  EPA   request   involves   French  Island   and  whether  its
classification  in  the "small municipal waste combustor" category under Section
129 of the Clean Air Act is appropriate. This request was made as a result of an
inquiry  to  the  EPA  brought  by  the  Midwest   Environmental  Advocates,  an
environmental  legal  foundation  recently  formed  in Madison, Wis. The EPA has
already  concluded,  based on past data submissions that French Island should be
classified as a "small combustor". NSP-Wisconsin has resubmitted the operational
and  design  data  that  was  used for the original determination and additional
information  to  confirm  the  classification.

     Both facility data responses were submitted to the EPA. These are the first
Section  114(a)  requests  NSP-Wisconsin  has ever received. These types of data
requests are increasing in frequency in Wisconsin as a result of  the EPA's more
aggressive  enforcement  policy.

4. SEGMENT  INFORMATION

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

     Discussion  of  financial condition and liquidity is omitted per conditions
set  forth  in  general instructions H (1) and (2) of Form 10-Q for wholly-owned
subsidiaries  (reduced  disclosure  format).

     Except  for the historical statements contained in this report, the matters
discussed  in  the  following  discussion  and    analysis  are  forward-looking
statements  that  are  subject  to certain risks, uncertainties and assumptions.
Such  forward-looking  statements are intended to be identified in this document
by  the  words  "anticipate",  "estimate",  "expect",  "objective",  "possible",
"potential"  and  similar  expressions.    Actual  results  may vary materially.
Factors  that  could  cause actual results to differ materially include, but are
not  limited  to:

- - general economic conditions, including their impact on capital expenditures;
- - business  conditions  in  the  energy  industry;
- - competitive  factors;
- - unusual  weather;
- - changes  in  federal  or  state  legislation;
- - regulation;
- - the items set forth below under "Factors Affecting Results of Operations";
- - and  the other  risk factors listed from time to time by NSP in reports  filed
  with the Securities and Exchange Commission (SEC), including Exhibit 99.01  to
  this  report  on  Form  10-Q  for  the  quarter  ended  June  30,  2000.

                              RESULTS OF OPERATIONS
                              ---------------------

     On  March  24,  1999,  NSP  and  NCE  agreed  to merge. It is expected that
NSP-Wisconsin  will  continue  to exist as an operating subsidiary of the merged
company.    The  following  discussion  and  analysis  is based on the financial
condition  and  operations  of  NSP-Wisconsin and does not reflect the potential
effects  of  the  combination  between  NSP  and  NCE.

FACTORS  AFFECTING  RESULTS  OF  OPERATIONS
- -------------------------------------------

     In addition to items noted in the Notes to the Financial Statements of this
report,  the  historical  and future trends of NSP-Wisconsin's operating results
are  affected  by  the  following  factors:

     VARIATIONS  IN WEATHER CONDITIONS -  Both electric and gas sales levels are
significantly  affected  by  variations  in  weather  conditions.  NSP-Wisconsin
estimates  sales  levels  under  normal  weather  conditions  and  analyzes  the
approximate  effect of variations from historical average temperatures on actual
sales levels.  The estimated impact of weather on operating revenues in relation
to  sales under normal weather conditions is shown in the discussion of electric
revenues  and  gas  revenues.

     SALES  GROWTH  -  The  following table summarizes NSP-Wisconsin's growth in
actual electric and gas sales and growth on a weather normalized (W/N) basis for
the  six-month period ended June 30, 2000, as compared with the six-month period
ended  June 30, 1999.  NSP-Wisconsin's weather normalization process removes the
estimated  impact  on  sales of temperature variations from historical averages.

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

FIRST  SIX  MONTHS  2000  COMPARED  WITH  FIRST  SIX  MONTHS  1999
- ------------------------------------------------------------------

     ELECTRIC  REVENUES for the first six months of 2000 increased $4.8 million,
or 2.4 percent, compared with the first six months of 1999.  The following table
summarizes  the  change  in  electric  revenues.   Power supply and transmission
revenue  relates  to  interchange agreement revenues received from NSP-Minnesota
and  reflect  a  net decrease in NSP-Wisconsin's fuel and transmission expenses.

     ELECTRIC  MARGIN  equals  electric  revenues  minus   production  expenses,
consisting of purchased and interchange power and fuel for  electric generation.

     Electric  production  expenses  tend  to  vary  with  changing  retail  and
wholesale  sales requirements and unit cost changes in fuel and purchased power.
The table below summarizes the principal reasons for electric margin changes for
the  six  months  ended  June 30, 2000 compared to the six months ended June 30,

15.5  percent,  compared with the first six months of 1999.  The following table
summarizes  the  change  in  gas  revenues.    Changes in per unit gas costs are
reflected  in  customer  rates  through  the  gas  cost  recovery  mechanism.

     GAS  MARGIN  equals  gas  revenues  minus  the  cost  of  gas  sold.

     The  cost  of  gas  tends to vary with changing sales requirements and unit
cost  of gas purchased.  However, due to the gas cost recovery mechanism, nearly
all  fluctuations  in  the  cost of gas have no effect on gas margin.  The table
below  summarizes the principal reasons for gas margin changes for the six month
period  ended  June  30,  2000 compared with the six month period ended June 30,
1999.

     OTHER  OPERATING,  MAINTENANCE,  CONSERVATION DEMAND SIDE MANAGEMENT (DSM),
AND  ADMINISTRATIVE  AND GENERAL (A&G) expenses together increased $1.2 million,
or  2.5  percent, in the first six months of 2000 compared to the same period in
1999.    The  increase  is   due primarily to increased employee  benefit costs,
higher authorized  DSM,   customer service expenses,  and transmission  expenses
offset by lower amortization expenses for Network Transmission System  deferrals
and maintenance  expenses.

     DEPRECIATION  AND  AMORTIZATION  expense  decreased  $0.6  million,  or 2.7
percent,  in the first six months of 2000 compared to 1999.  The decrease is due
mainly  to lower rates resulting from the change to the remaining life technique
for  production  facilities  and  data  processing equipment under general plant
amortization  becoming  fully depreciated in 1999.  In addition, average service
life  rate  changes  implemented  as  the  result of a recent depreciation study
decreased depreciation expense.  As discussed in the 1999 Form 10-K Rate Matters
by Jurisdiction section, the new rates and new depreciation method authorized by
the  PSCW  were  effective  Jan.  1,  2000.
