NOTES TO FINANCIAL STATEMENTS

     In the opinion of management, the accompanying unaudited consolidated and stand-alone financial statements contain all adjustments necessary to present fairly the financial position of NSP-Minnesota, NSP-Wisconsin, PSCo and SPS (collectively referred to as the Utility Subsidiaries of Xcel Energy) as of March 31, 2002, and Dec. 31, 2001, the results of their operations for the three months ended March 31, 2002 and 2001, and their cash flows for the three months ended March 31, 2002 and 2001. Due to the seasonality of electric and gas sales of Xcel Energy’s Utility Subsidiaries, quarterly results are not necessarily an appropriate base from which to project annual results.

     The accounting policies of NSP-Minnesota, NSP-Wisconsin, PSCo and SPS are set forth in Note 1 to the financial statements in their respective Annual Reports on Form 10-K for the year ended Dec. 31, 2001. The following notes should be read in conjunction with such policies and other disclosures in the Form 10-K’s.

     We reclassified certain items in the 2001 income statement to conform to the presentation disclosed in the 2001 Annual Report on Form 10-K. These reclassifications had no effect on stockholders’ equity, net income or earnings per share as previously reported. The reclassifications were primarily to conform the presentation of all consolidated Xcel Energy subsidiaries to a standard corporate presentation.

1.     Accounting Changes (NSP-Minnesota, NSP-Wisconsin, PSCo and SPS)

     Intangible Assets —During the first quarter of 2002, the Utility Subsidiaries of Xcel Energy adopted Statement of Financial Accounting Standard (SFAS) No. 142 — “Goodwill and Other Intangible Assets” (SFAS No. 142), which requires new accounting for intangible assets, including goodwill. Intangible assets with finite lives will be amortized over their economic useful lives and periodically reviewed for impairment. Goodwill will no longer be amortized, but would be required to be tested for impairment annually and on an interim basis if an event occurs or a circumstance changes between annual tests that may reduce the fair value of a reporting unit below its carrying value.

     The Utility Subsidiaries of Xcel Energy had no intangible assets which will not be amortized under SFAS No. 142.

     With respect to those intangible assets that will continue to be amortized, aggregate amortization expense recognized in the first quarter of 2002 was approximately $60,000. The annual aggregate amortization expense for each of the five succeeding years is expected to approximate $0.24 million. Intangible assets subject to amortization at March 31, 2002, consisting primarily of deferred employment agreement costs, were as follows:

	March 31, 2002				Dec. 31, 2001
	Gross Carrying		Accumulated		Gross Carrying		Accumulated
	Amount		Amortization		Amount		Amortization
	(Thousands of Dollars)
NSP-Minnesota		4,867		385		4,867		324
NSP-Wisconsin		—		—		—		—
PSCo		—		—		—		—
SPS		—		—		—		—

     Asset Valuation —On Jan. 1, 2002, the Utility Subsidiaries adopted SFAS No. 144 — “Accounting for the Impairment or Disposal of Long-Lived Assets,” which supercedes previous guidance for measurement of asset impairments. The Utility Subsidiaries did not recognize any asset impairments as a result of the adoption. The method used in determining fair value was based on a number of valuation techniques, including present value of future cash flows.

NOTES TO FINANCIAL STATEMENTS — (Continued)

2.     Special Charges (NSP-Minnesota, NSP-Wisconsin, PSCo and SPS)

     2002 Regulatory Recovery Adjustment —In late 2001, SPS filed an application requesting recovery of costs incurred to comply with transition to retail competition legislation in Texas and New Mexico. During the first quarter of 2002, SPS entered into a settlement agreement with intervenors regarding the recovery of restructuring costs in Texas, subject to approval by the state regulatory commission. Based on the settlement agreement, SPS wrote off pretax restructuring costs of approximately $5 million.

     2002/2001 Restaffing —During the fourth quarter of 2001, Xcel Energy expensed pretax special charges of $39 million for expected staff consolidation costs for 500 employees. Approximately $36 million of these restaffing costs were allocated to Xcel Energy’s Utility Subsidiaries consistent with service company cost allocation methodologies utilized under the requirements of the PUHCA. In the first quarter of 2002, additional pretax special charges of $9 million were expensed for additional staff consolidations. Approximately $5 million of these restaffing costs were allocated to Xcel Energy’s Utility Subsidiaries. The charges related to severance costs for utility operations resulting from restaffing plans of several operating and corporate support areas of Xcel Energy. Staff terminations of 564 are now expected to occur. As of March 31, 2002, 551 of these terminations had occurred.

     The following table summarizes the activity related to accrued special charges (reported in other current liabilities) for the first three months of 2002.

3.     Business Developments (NSP-Minnesota, NSP-Wisconsin, PSCo and SPS)

     TRANSLink Transmission Company, LLC (TRANSLink) —In September 2001, Xcel Energy and several other electric utilities applied to the Federal Energy Regulatory Commission (FERC) to integrate operations of their electric transmission systems into a single system through the formation of TRANSLink, a for-profit, transmission-only company. The utilities will participate in TRANSLink through a combination of divestiture, leases and operating agreements. The applicants are: Alliant Energy’s Iowa company (Interstate Power and Light Co.), Corn Belt Power Cooperative, MidAmerican Energy Co., Nebraska Public Power District, Omaha Public Power District and Xcel Energy. The participants believe TRANSLink is the most cost-efficient option available to manage transmission and to comply with regulations issued by the FERC in 1999 (known as Order No. 2000) that require investor-owned electric utilities to transfer operational control of their transmission system to an independent regional transmission organization (RTO).

     Under the proposal, TRANSLink will be responsible for planning, managing and operating both local and regional transmission assets. TRANSLink will also construct and own new transmission system additions. TRANSLink will collect the revenue for the use of Xcel Energy’s transmission assets through a FERC-approved, regulated cost-of-service tariff and will collect its administrative costs through transmission rate

surcharges. Transmission service pricing will continue to be regulated by the FERC, but construction and permitting approvals will continue to rest with regulators in the states served by TRANSLink. The participants also have entered into a memorandum of understanding with the Midwest Independent Transmission Operator, Inc. (MISO) in which they agree that TRANSLink will contract with the MISO for certain other required RTO functions and services.

     In April 2002, the FERC gave conditional approval for the applicants to transfer ownership or operations of their transmission systems to TRANSLink and to form TRANSLink as an independent transmission company operating under the umbrella organization of MISO and a separate RTO in the west (once it is formed) for Public Service Company of Colorado (PSCo) assets. The FERC conditioned TRANSLink’s approval on the resubmission of its tariff as a separate schedule to be administered by the MISO. Several state approvals also would be required to implement the proposal, as well as SEC approval. Subject to receipt of required regulatory approvals, TRANSLink is expected to begin operations in early 2003.

4.     Restructuring and Regulation (PSCo and SPS)

     Colorado Rate Proceedings — Incentive Cost Adjustment —Under the Stipulation and Agreement approved by the Colorado Public Utilities Commission (CPUC) in connection with the Xcel Energy merger, PSCo agreed to 1) file a combined electric, gas and steam rate case in 2002 with new rates effective in January 2003, 2) extend its incentive cost adjustment (ICA) mechanism for one more year through Dec. 31, 2002, with an increase in the ICA base rate from $12.78 per megawatt hour to a rate based on the 2001 actual costs, 3) continue the Performance-Based Regulatory Plan and the Quality Service Plan through 2006 with an electric department earnings cap of 10.5 percent return on equity for 2002, 4) reduce electric rates annually by $11 million for the period August 2000 to July 2002 and 5) cap merger costs associated with electric operations at $30 million and amortize such costs through 2002. The general rate case is being prepared and is expected to be filed by the end of May 2002.

     In early 2002, PSCo filed to increase rates under the ICA to recover the undercollection of costs through the period ended Dec. 31, 2001 (approximately $14.5 million, which went into effect on April 15, 2002), and to increase the ICA base rate for the recovery of 2002 costs, which are projected to be substantially higher than the $12.78 per megawatt hour currently being recovered. PSCo’s actual ICA base costs for 2001 were approximately $19 per megawatt hour. PSCo proposed to increase the ICA base in 2002 to avoid the significant deferral of costs and a large rate increase in 2003, although the Stipulation and Agreement provided for a rate recovery period of April 1, 2003, to March 31, 2004.

     On May 10, 2002, the CPUC approved a Settlement Agreement between PSCo and other parties to increase the ICA base rate to $14.88 per megawatt hour, providing for recovery of the deferred 2001 costs and the projected higher 2002 costs over a 34-month period from June 1, 2002, to March 31, 2005. The review and approval of actual costs incurred and recoverable under the ICA for 2001 and 2002 will be conducted in future rate proceedings by the CPUC for consideration of further increases in the ICA base rate to $19.00 per megawatt hour. PSCo is currently projecting its costs for 2002 to be approximately $38 million less than the ICA base allowed using the 2001 test year, resulting in an equal sharing of such lower costs between retail customers and PSCo. The mechanism for recovering fuel and energy costs for 2003 and later will be addressed in the 2002 rate case.

     Colorado Rate Proceedings — Gas Cost Prudence Review —In May 2002, the staff of the CPUC filed testimony in PSCo’s gas cost prudence review case, recommending $6.1 million in disallowances of gas costs for the July 2000 through June 2001 gas purchase year. PSCo’s rebuttal testimony is scheduled to be filed on June 26, 2002. Hearings are scheduled for July 2002.

     FERC Investigation —On May 8, 2002, the FERC ordered all sellers of wholesale electricity and/or ancillary services to the California Independent System Operator or Power Exchange, including PSCo, to respond to data requests, including requests for admissions with respect to certain trading strategies in which the companies may have engaged. The investigation is in response to memoranda prepared by Enron

17

NOTES TO FINANCIAL STATEMENTS — (Continued)

Corporation that detail certain trading strategies engaged in 2000 and 2001, which may have violated market rules. Xcel Energy must respond by May 22, 2002.

     SPS Texas Transition to Competition Cost Recovery Application —In December 2001, SPS filed an application with the Public Utility Commission of Texas (PUCT) to recover $20.3 million in transition to retail competition costs from the Texas retail customers. These costs are associated with the SPS’ delayed transition to competition. The filing was amended in March 2002 to reduce the recoverable costs by $7.3 million, which were associated with over-earnings recognized in 2001 for the 1999 annual report to the PUCT. The PUCT approved SPS using the 1999 annual report over-earnings to offset the claims for reimbursement of transition to competition costs. This reduced the requested net collection in Texas to $13.0 million. In April 2002, a unanimous settlement agreement was reached. Final approval by the PUCT is expected May 23, 2002. The stipulation provides for the recovery of $5.9 million through an incremental cost recovery rider and the capitalization of $1.9 million for metering equipment. Based on the settlement agreement, SPS wrote off pretax restructuring costs of approximately $5 million in the first quarter of 2002. Recovery of the $5.9 million will begin in July 2002.

5.     Commitments and Contingent Liabilities (NSP-Minnesota, NSP-Wisconsin, PSCo and SPS)

     Lawsuits and claims arise in the normal course of business. Management, after consultation with legal counsel, has recorded an estimate of the probable cost of settlement or other disposition of them.

     Xcel Energy’s Utility Subsidiaries have been or are currently involved with the cleanup of contamination from certain hazardous substances at several sites. In many situations, Xcel Energy’s Utility Subsidiaries are pursuing, or intend to pursue, insurance claims and believe they will recover some portion of these costs through such claims. Additionally, where applicable, Xcel Energy’s Utility Subsidiaries are pursuing, or intend to pursue, recovery from other potentially responsible parties and through the rate regulatory process. To the extent any costs are not recovered through the options listed above, Xcel Energy’s Utility Subsidiaries would be required to recognize an expense for such unrecoverable amounts.

     The circumstances set forth in Notes 13 and 14 to the financial statements in NSP-Minnesota’s, NSP-Wisconsin’s, PSCo’s and SPS’ Annual Reports on Form 10-K for the year ended Dec. 31, 2001, appropriately represent, in all material respects, the current status of commitments and contingent liabilities, including those regarding public liability for claims resulting from any nuclear incident and are incorporated herein by reference. Following are unresolved contingencies, which are material to the financial position of Xcel Energy’s Utility Subsidiaries:

•  Tax Matters — Tax deductibility of corporate owned life insurance loan interest

6.     Short-Term Borrowings and Financing Activities (NSP-Minnesota, NSP-Wisconsin and PSCo)

     NSP-Minnesota

     At March 31, 2002, NSP-Minnesota had approximately $376 million of short-term debt outstanding at a weighted average interest rate of 3.153 percent.

     NSP-Wisconsin

     At March 31, 2002, NSP-Wisconsin had approximately $9 million of short-term notes payable to NSP-Minnesota outstanding at a weighted average interest rate of 3.153 percent.

     PSCo

     At March 31, 2002, PSCo had approximately $545 million of short-term debt outstanding at a weighted average interest rate of 3.097 percent.

NOTES TO FINANCIAL STATEMENTS — (Continued)

7.     Derivative Valuation and Financial Impacts (NSP-Minnesota, PSCo and SPS)

     Xcel Energy’s Utility Subsidiaries analyze derivative financial instruments in accordance with SFAS No. 133 — “Accounting for Derivative Instruments and Hedging Activities” (SFAS No. 133). This statement requires that all derivative financial instruments be recorded on the balance sheet at fair value unless exempted. Changes in a derivative instrument’s fair value must be recognized currently in earnings unless the derivative has been designated in a qualifying hedging relationship. The application of hedge accounting allows a derivative instrument’s gains and losses to offset related results of the hedged item in the income statement, to the extent effective. SFAS No. 133 requires that the hedging relationship be highly effective and that a company formally designate a hedging relationship to apply hedge accounting.

     The components of SFAS No. 133 impacts on Other Comprehensive Income, included in stockholders’ equity, are detailed in the following table:

	Three Months Ended
	March 31, 2002
	NSP-Minnesota			PSCo			SPS

Accumulated other comprehensive loss related to SFAS No. 133 — March 31, 2001	$	(0.0	)	$	(2.8	)	$	(3.8	)

     PSCo recorded pretax gains in Electric Fuel and Purchased Power of $0.1 million and $1.1 million for the three months ended March 31, 2002 and 2001, respectively, due to the effects of SFAS No. 133. NSP-Minnesota and SPS did not realize any impact to earnings related to SFAS No. 133 during the period.

Normal Purchases or Normal Sales

     Xcel Energy’s Utility Subsidiaries enter into fixed price contracts for the purchase and sale of various commodities for use in their business operations. SFAS No. 133 requires a company to evaluate these contracts to determine whether the contracts are derivatives. Certain contracts that literally meet the definition of a derivative may be exempted from SFAS No. 133 as normal purchases or normal sales. Normal purchases and normal sales are contracts that provide for the purchase or sale of something other than a financial instrument or derivative instrument that will be delivered in quantities expected to be used or sold over a reasonable period in the normal course of business. Contracts that meet the requirements of normal are documented as normal and exempted from the accounting and reporting requirements of SFAS No. 133.

19

NOTES TO FINANCIAL STATEMENTS — (Continued)

     Xcel Energy’s Utility Subsidiaries evaluate all of their contracts when such contracts are entered into to determine if they are derivatives and, if so, if they qualify and meet the normal designation requirements under SFAS No. 133. None of the contracts entered into within the trading operations are considered normal under the provisions of SFAS No. 133.

     Normal purchases and normal sales contracts are accounted for as executory contracts as required under other generally accepted accounting principles.

Cash Flow Hedges

     NSP-Minnesota, PSCo and SPS enter into derivative instruments to manage their respective exposure to changes in commodity prices. These derivative instruments take the form of fixed price, floating price or index sales or purchases and options, such as puts, calls and swaps. These derivative instruments are designated as cash flow hedges for accounting purposes and the changes in the fair value of these instruments are recorded as a component of Other Comprehensive Income. At March 31, 2002, NSP-Minnesota, PSCo and SPS had various commodity related contracts through the next 12 months. Earnings on these cash flow hedges are recorded as the hedged purchase or sales transaction is completed. This could include the physical sale of electric energy or the usage of natural gas to generate electric energy. As of March 31, 2002, NSP-Minnesota and PSCo expect to reclassify into earnings through March 2003 net (losses) gains from Other Comprehensive Income of approximately $(0.2) million and $3.6 million, respectively. SPS expects to reclassify an immaterial amount from Other Comprehensive Income into earnings through March 2003.

     As required by SFAS No. 133, PSCo recorded gains of $0.1 million and $0.3 million related to ineffectiveness on commodity cash flow hedges during the three months ended March 31, 2002 and 2001, respectively. During the first quarter of 2001, PSCo recorded gains of $1.4 million related to derivative financial instruments excluded from the assessment of effectiveness and an immaterial amount related to cash flow hedges that were discontinued because the hedged transactions were no longer probable.

     SPS enters into interest rate swap instruments that effectively fix the interest payments on certain floating rate debt obligations. These derivative instruments are designated as cash flow hedges for accounting purposes and the change in the fair value of these instruments is recorded as a component of Other Comprehensive Income. SPS expects to reclassify into earnings through March 2003 net losses from Other Comprehensive Income of approximately $0.7 million.

     Hedge effectiveness is recorded based on the nature of the item being hedged. Hedging transactions for the sales of electric energy are recorded as a component of revenue, hedging transactions for fuel used in energy generation are recorded as a component of fuel costs and hedging transactions for interest rate swaps are recorded as a component of interest expense.

Derivatives Not Qualifying for Hedge Accounting

     NSP-Minnesota and PSCo have trading operations that enter into derivative instruments. These derivative instruments are accounted for on a mark-to-market basis in their respective Consolidated Statements of Income. All financial derivative instruments are recorded at the amount of the gain or loss from the transaction within Operating Revenues on the Consolidated Statements of Income.

Item 2.     Management’s Discussion and Analysis

     Discussion of financial condition and liquidity for the Utility Subsidiaries of Xcel Energy are omitted per conditions set forth in general instructions H(1)(a) and (b) of Form 10-Q for wholly owned subsidiaries. It is replaced with management’s narrative analysis and the results of operations set forth in general instructions H(2)(a) of Form 10-Q for wholly owned subsidiaries (reduced disclosure format).

Forward-Looking Information

     The following discussion and analysis by management focuses on those factors that had a material effect on the financial condition and results of operations of Xcel Energy’s Utility Subsidiaries during the periods presented, or are expected to have a material impact in the future. It should be read in conjunction with the accompanying unaudited Financial Statements and Notes.

     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,” “outlook,” “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 and the ability of Xcel Energy’s Utility Subsidiaries to obtain financing on favorable terms;

•  business conditions in the energy industry;

•  competitive factors, including the extent and timing of the entry of additional competition in the markets served by the Utility Subsidiaries of Xcel Energy;

•  unusual weather;

•  state, federal and foreign legislative and regulatory initiatives that affect cost and investment recovery, have an impact on rate structures and affect the speed and degree to which competition enters the electric and gas markets;

•  risks associated with the California and other western power markets; and

•  the other risk factors listed from time to time by the Utility Subsidiaries of Xcel Energy 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 March 31, 2002.

Market Risks

     The Utility Subsidiaries of Xcel Energy are exposed to market risks, including changes in commodity prices and interest rates as disclosed in Management’s Discussion and Analysis in their annual reports on Form 10-K for the year ended Dec. 31, 2001. Commodity price and interest rate risks for the Utility Subsidiaries of Xcel Energy are mitigated in most jurisdictions due to cost-based rate regulation. There have been no material changes in the market risk exposures that affect the quantitative and qualitative disclosures presented as of Dec. 31, 2001.

Pending Accounting Changes

     SFAS No. 143 —In 2001, the Financial Accounting Standards Board issued SFAS No. 143 — “Accounting for Asset Retirement Obligations.” This statement will require NSP-Minnesota to record its future nuclear plant decommissioning obligations as a liability at fair value with a corresponding increase to the carrying value of the related long-lived asset. The liability will be increased to its present value each period, and the capitalized cost will be depreciated over the useful life of the related long-lived asset. If at the end of the asset’s life the recorded liability differs from the actual obligations paid, SFAS No. 143 requires that a gain or loss be recognized at that time.

24

     NSP-Minnesota currently follows industry practice by ratably accruing the costs for decommissioning over the approved cost recovery period and including the accruals in accumulated depreciation. At Dec. 31, 2001, NSP-Minnesota recorded and recovered in rates $623 million of decommissioning obligations and had estimated discounted decommissioning cost obligations of $878 million.

     If NSP-Minnesota adopted the standard on Jan. 1, 2002, the initial value of the liability, including cumulative interest expense through that date, would have been approximately $757 million, with a corresponding increase to net plant assets of approximately $625 million. The resulting cumulative effect adjustment for unrecognized depreciation and other expenses under the new standard is approximately $132 million. Management expects that the entire transition amount would be recoverable in rates and, therefore, would recognize an additional regulatory asset upon adoption of SFAS No. 143 rather than incur a cumulative effect charge against earnings.

     SFAS No. 143 also will affect accrued plant removal costs for other generation, transmission and distribution facilities for all of the Utility Subsidiaries. Xcel Energy expects that these costs, which have yet to be estimated, are expected to be reclassified from accumulated depreciation to regulatory liabilities based on the treatment of these costs in rates. Xcel Energy expects to adopt SFAS 143 as required on Jan. 1, 2003.

     SFAS No. 145 —In April 2002, the FASB issued SFAS No. 145 — “Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical Corrections,” that supercedes previous guidance for the reporting of gains and losses from extinguishment of debt and accounting for leases, among other things. The impact of SFAS No. 145 is not expected to be material to any of the Utility Subsidiaries of Xcel Energy.

NSP-MINNESOTA’S MANAGEMENT’S DISCUSSION AND ANALYSIS

Results of Operations

     NSP-Minnesota’s net income was approximately $33.0 million for the first three months of 2002, compared with approximately $42.2 million for the first three months of 2001.

     Electric Utility and Commodity Trading Margins

     Electric fuel and purchased power expense tend to vary with changing retail and wholesale sales requirements and unit cost changes in fuel and purchased power. Due to fuel cost recovery mechanisms for retail customers, most fluctuations in energy costs do not affect electric utility margin.

     Some electric commodity trading activity, initially recorded at NSP-Minnesota and PSCo, is partially redistributed between NSP-Minnesota, PSCo and SPS pursuant to the Joint Operating Agreement (JOA) approved by the FERC. Trading revenue and costs do not include the revenue and production costs associated with energy produced from NSP-Minnesota’s generation assets or energy and capacity purchased to serve native load. Margins from these generating assets for utility operations (excluding sales to retail and municipal customers) are included in short-term wholesale amounts, detailed below. The following table details electric utility, short-term wholesale and electric commodity trading revenue and margin:

							Electric
	Electric			Short-term			Commodity			Consolidated
	Utility			Wholesale			Trading			Total

Gross margin before operating expenses	$	358		$	13		$	—		$	371
Margin as a percentage of revenue		63.0	%		28.3	%		—			60.4	%

     Electric utility revenues decreased by $54 million, or 9.5 percent, in the first quarter of 2002, compared with the same period in 2001. Electric utility margins decreased by $10 million, or 2.8 percent in 2002 when compared with 2001. The decrease in revenues and margins reflect lower shared trading margins recorded through the JOA and warmer temperatures in 2002. Revenues also were reduced by lower purchased power costs recovered through electric rates. These decreases in revenues and margin were partially offset by sales growth and the timing of recognition of conservation incentive revenues.

     Short-term wholesale margins decreased in the first three months of 2002, compared with the first three months of 2001. The decrease is due to declines in energy prices.

26

     Gas Utility Margins

     The following table details the change in gas revenue and margin. The cost of gas tends to vary with changing sales requirements and unit cost of gas purchases. However, due to purchased gas cost recovery mechanisms for retail customers, fluctuations in the cost of gas have little effect on gas margin.

	Three Months Ended
	March 31
	2002			2001
	(Millions of Dollars)
Gas revenue	$	188		$	353
Cost of gas sold and transported		(128	)		(288	)
Gas utility margin	$	60		$	65

     Gas revenue decreased by approximately $165 million, or 46.7 percent, in the first quarter of 2002, primarily due to decreases in the cost of natural gas, which are largely passed on to customers and recovered through various rate adjustment clauses. Gas margin for the first three months of 2002 decreased by $5 million, or 7.7 percent, compared with the first three months of 2001, primarily due to warmer winter temperatures in the first three months of 2002.

     Non-Fuel Operating Expense and Other Items

     Other Operating and Maintenance Expense increased by approximately $6 million, or 2.8 percent, for the first three months of 2002, compared with the first three months of 2001. The increased costs in the first quarter reflect higher outage costs, higher property insurance premiums and higher nuclear operating costs.

     Depreciation and Amortization Expense increased by approximately $2.3 million, or 2.7 percent, for the first three months of 2002, compared with the first three months of 2001, primarily due to capital additions to utility plant.

     As discussed in Note 2 to the Financial Statements, during the fourth quarter of 2001 NSP-Minnesota expensed pretax special charges for planned staff consolidation costs. In the first quarter of 2002, additional pretax special charges of $4.3 million were expensed for the final costs of staff consolidations. The charges related to severance costs for utility operations resulting from restaffing plans of several operating and corporate support areas of Xcel Energy.

     Other Income (Expense) — net increased by $8.9 million, due primarily to a gain on the sale of property by a subsidiary of NSP-Minnesota, First Midwest Auto Park, in March 2002.

     Interest charges and financing costs decreased by approximately $7.5 million, or 30.0 percent, for the first three months of 2002, compared with the first three months of 2001. The change is largely due to lower average debt levels and lower short-term interest rates.

     Taxes (other than income taxes) declined largely due to a legislative change in Minnesota that reduced annual property taxes by approximately $30 million in September 2001 that related proportionately to the first nine months of 2001. Approximately 70 percent of this reduction in property taxes will be returned to NSP-Minnesota customers.

NSP-WISCONSIN’S MANAGEMENT’S DISCUSSION AND ANALYSIS

Results of Operations

     NSP-Wisconsin’s net income was $18.0 million for the first three months of 2002, compared with $13.1 million for the first three months of 2001.

     Electric Utility Margins

     The following table details the change in electric revenue and margin. Electric production expenses tend to vary with the quantity of electricity required and changes in the unit costs of fuel and purchased power. The fuel and purchased power cost recovery mechanism of the Wisconsin jurisdiction does not allow for complete recovery of all expenses and, therefore, dramatic changes in costs or periods of extreme temperatures can adversely affect earnings.

		Three Months Ended
		March 31,
		2002			2001
		(Millions of Dollars)
Total electric utility revenue		$	117		$	114
Electric fuel and purchased power			(55	)		(61	)
	Total electric utility margin	$	62		$	53

     Electric utility revenue increased by approximately $3 million, or 2.6 percent, in the first three months of 2002, compared with the first three months of 2001. Electric utility margin increased by approximately $9 million, or 16.9 percent, in the first three months of 2002, compared with the first three months of 2001. The revenue increase reflects a rate increase and sales growth, partially offset by the impact of warmer weather. The increase in electric margin is primarily due to lower fuel and purchased power costs in 2002 and an increase in base electric rates effective Oct. 18, 2001, for Wisconsin retail customers. Warmer temperatures in 2002, compared with 2001, reduced electric margins.

     Gas Utility Margins

     The following table details the change in gas revenue and margin. The cost of gas tends to vary with changing sales requirements and unit cost of gas purchases. However, due to purchase gas cost recovery mechanisms for retail customers, fluctuations in the cost of gas have little effect on gas margin.

	Three Months Ended
	March 31
	2002			2001
	(Millions of Dollars)
Gas revenue	$	40		$	70
Cost of gas purchased and transported		(29	)		(57	)
Gas margin	$	11		$	13

     Gas revenue for the first three months of 2002 decreased by $30 million, or 42.9 percent, compared with the first three months of 2001, due to lower sales and decreases in the cost of gas, which is recovered in Wisconsin through the purchased gas adjustment clause mechanism. Gas margin for the first three months of 2002 decreased by $2 million, or 15.4 percent, compared with the first three months of 2001, primarily due to less favorable temperatures in 2002.

Non-Fuel Operating Expense and Other Items

     Other Operating and Maintenance Expense for the first three months of 2002 decreased by $1.6 million, or 6.2 percent, compared with the first three months of 2001, primarily due to lower conservation expenditures and lower shared costs in 2002.

28

     Depreciation and Amortization Expense increased by approximately $0.5 million, or 5.0 percent, for the first three months of 2002, compared with the first three months of 2001, due largely to increased capital additions to utility plant.

     As discussed in Note 2 to the Financial Statements, during fourth the quarter of 2001, NSP-Wisconsin expensed pretax special charges for planned staff consolidation costs. In the first quarter of 2002, additional pretax special charges of $0.5 million were expensed for the final costs of staff consolidations. The charges related to severance costs for utility operations resulting from restaffing plans of several operating and corporate support areas of Xcel Energy.

     Other Income (Expense) — net increased $0.5 million, or 179.6 percent, for the first three months of 2002, compared with the first three months of 2001, primarily due to interest income received on outstanding economic development loans.

     Interest expense increased by approximately $0.3 million, or 5.3 percent, for the first three months of 2002, compared with the first three months of 2001, due largely to a regulatory amortization for an interest refund in 2001 that did not recur in 2002.

29

PSCo’S MANAGEMENT’S DISCUSSION AND ANALYSIS

Results of Operations

     PSCo’s net income was approximately $66.7 million for the first three months of 2002, compared with approximately $107.4 million for the first three months of 2001.

     Electric Utility and Commodity Trading Margins

     Electric production expenses tend to vary with changing retail and wholesale sales requirements and unit cost changes in fuel and purchased power. Due to fuel clause cost recovery mechanisms for retail customers in Colorado, most fluctuations in energy costs do not materially affect electric margin. Electric margins reflect the impact of sharing energy costs and savings relative to a target cost per delivered kilowatt hour and certain trading margins under the ICA. In addition to the ICA, PSCo has other adjustment clauses that allow certain costs to be passed through to retail customers. The Qualifying Facilities Capacity Cost Adjustment (QFCCA) provides for recovery of purchased capacity costs from certain Qualifying Facilities projects not otherwise reflected in based electric rates. The fuel clause cost recovery does not allow for complete recovery of all variable production expenses and higher costs can adversely affect earnings.

     Some electric commodity trading activity, initially recorded at PSCo, is partially redistributed to NSP-Minnesota and SPS pursuant to the JOA approved by the FERC. Trading revenue and costs do not include the revenue and production costs associated with energy produced from PSCo’s generation assets or energy and capacity purchased to serve native load. Margins from these generating assets for utility operations are included in short-term wholesale amounts, discussed later. Trading margins reflect the impact of sharing certain trading margins under the ICA. The following table details electric utility, short-term wholesale and electric trading revenue and margin.

Margin as a percentage of revenue		50.4	%		30.1	%		7.0	%		30.4	%

     Electric utility margin increased by approximately $53 million, or 29.9 percent, in the first three months of 2002, compared with the first three months of 2001. The higher electric margins reflect lower unrecovered costs, due in part to resetting the base-cost recovery factor through the ICA in January 2002.

30

     Short-term wholesale margins and electric commodity trading margins decreased substantially in the first three months of 2002, compared with the first three months of 2001. The decrease is due to declines in energy prices. During 2001, in some Western markets, publicly available power prices ranged from $80 to more than $350 per megawatt-hour on a monthly average. Forward price information for 2002 for these same areas ranges from $60 to $110 per megawatt-hour on a monthly average.

     Gas Utility Margins

     The following table details the change in gas revenue and margin. The cost of gas tends to vary with changing sales requirements and unit cost of gas purchases. PSCo has a Gas Cost Adjustment mechanism for natural gas sales, which recognizes the majority of the effects of changes in the cost of gas purchased for resale and adjusts revenues to reflect such changes in costs on a timely basis. Therefore, fluctuations in the cost of gas have little effect on gas margin.

	Three Months Ended

	(Millions of Dollars)
Gas revenue	$	317		$	548
Cost of gas purchased and transported		(211	)		(448	)
Gas margin	$	106		$	100

     Gas revenue for the first three months of 2002 decreased by approximately $231 million, or 42.2 percent, compared with the first three months of 2001, largely due to lower gas costs recovered through rates. Gas margin for the first three months of 2002 increased by approximately $6 million, or 6.0 percent, compared with the first three months of 2001, primarily due to higher rates from a 2000 rate case, effective Feb. 1, 2001.

     Non-Fuel Operating Expense and Other Items

     Other Operation and Maintenance Expense increased by approximately $15.0 million, or 14.7 percent, for the first three months of 2002, compared with the first three months of 2001. The change is largely due to generation maintenance overhauls, higher information technology infrastructure costs and higher property insurance premiums.

     Depreciation and Amortization Expense increased by approximately $6.5 million, or 11.1 percent, for the first three months of 2002, compared with the first three months of 2001, primarily due to increased amortization costs of software and increased depreciation resulting from capital additions to utility plant.

     Other Income (Expense) — net for the first three months of 2001 included an $11-million gain on the sale of the Boulder Hydro facility recorded in March 2001.

     Interest expense decreased by approximately $2.5 million, or 8.3 percent, for the first three months of 2002, compared with the first three months of 2001. The decrease was primarily due to lower interest rates.

SPS’ MANAGEMENT’S DISCUSSION AND ANALYSIS

Results of Operations

     SPS’ net income was approximately $14.7 million for the first three months of 2002, compared with approximately $26 million for the first three months of 2001.

     Electric Utility Margins

     The following table details the change in electric revenue and margin. Electric production expenses tend to vary with changing retail and wholesale sales requirements and unit cost changes in fuel and purchased power. Fuel and purchased power costs are recoverable in SPS’ Texas jurisdiction through a fixed fuel factor, which is included in rates. In the New Mexico retail jurisdiction, fuel and purchased energy costs are adjusted through a fuel clause and a fixed annual factor. In all other jurisdictions, SPS currently recovers substantially all increases and refunds substantially all decreases in fuel and purchased power costs pursuant to monthly adjustment clauses. Due to these fuel clause cost recovery mechanisms for retail customers and the ability to vary wholesale prices with changing market conditions, most fluctuations in energy costs do not affect electric margin. However, the fuel clause cost recovery does not allow for complete recovery of all variable production expenses and, therefore, higher costs can adversely affect earnings.

     Electric revenue decreased by approximately $117 million, or 35.6 percent, for the first three months of 2002, compared with the first three months of 2001. Electric margin decreased by approximately $11 million, or 8.8 percent, for the first three months of 2002, compared with the first three months of 2001. Electric revenues decreased for the first three months of 2002, largely due to lower fuel and purchased power costs recovered through electric rates and lower sharing of commodity trading activity initially recorded at PSCo and NSP-Minnesota through the JOA approved by the FERC. The decrease in retail margin was primarily due to the lower revenues shared through the JOA.

     Non-Fuel Operating Expense and Other Costs

     Other Operation and Maintenance Expense increased by approximately $3.5 million, or 9.6 percent, for the first three months of 2002, compared with the first three months of 2001. The change is largely due to higher plant overhaul costs and higher property insurance premiums.

32

     Depreciation and Amortization Expense increased by approximately $1.7 million, or 8.6 percent, for the first three months of 2002, compared with the first three months of 2001, primarily due to increased depreciation from capital additions to utility plant.

     As discussed in Note 2 to the Financial Statements, in late 2001 SPS filed an application requesting a rate rider to recover costs incurred to comply with transition to retail competition legislation in Texas and New Mexico. During the first quarter of 2002, SPS entered into a settlement agreement with intervenors regarding the recovery of restructuring costs in Texas, subject to approval by the state regulatory commission. Based on the settlement agreement, SPS wrote off pretax restructuring costs of approximately $5 million.

PART II.     OTHER INFORMATION

Item 1.     Legal Proceedings

     In the normal course of business, various lawsuits and claims have arisen against the Utility Subsidiaries of Xcel Energy. Management, after consultation with legal counsel, has recorded an estimate of the probable cost of settlement or other disposition for such matters. See Notes 4 and 5 of the Financial Statements in this Form 10-Q for further discussion of legal proceedings, including Regulatory Matters and Commitments and Contingent Liabilities, which are hereby incorporated by reference. Reference also is made to Item 3 of NSP-Minnesota’s, NSP-Wisconsin’s, PSCo’s and SPS’ 2001 Form 10-K for a description of certain legal proceedings presently pending. There are no new significant cases to report against the Utility Subsidiaries of Xcel Energy and there have been no notable changes in the previously reported proceedings, except as set forth below.

NSP-Minnesota

     Light Rail Lawsuit —In February 2001, NSP-Minnesota filed a lawsuit in the federal district court in Minneapolis seeking reimbursement of costs for relocating electric utility lines to allow for construction of a light rail transit (LRT) line in downtown Minneapolis. In May 2001, the Minnesota Department of Transportation and the Metropolitan Council (Defendants) obtained a preliminary injunction requiring NSP-Minnesota to move certain facilities. NSP-Minnesota has complied with the preliminary injunction and utility line relocation has commenced. NSP-Minnesota is capitalizing its costs incurred as construction work in progress. In April 2002, Defendants brought motions for summary judgment before the federal district court. The court has not yet ruled on these motions and no trial date will be established until such ruling is made. The decision as to who must pay the cost of relocation will be made after trial. In collateral matters regarding LRT construction, NSP-Minnesota has commenced a mandamus action in state court seeking an order requiring Defendants to commence condemnation proceedings concerning an underground substation, access to which is blocked by LRT. NSP-Minnesota also has commenced an action in state court alleging that LRT construction violates the Minnesota Environmental Rights Act and a separate action in federal district court alleging that the Federal Transit Administration’s failure to evaluate certain environmental effects of LRT violates the National Environmental Policy Act.

NSP-Wisconsin

     Stray Voltage —On March 1, 2002, NSP-Wisconsin was served with a lawsuit commenced by James and Grace Gumz and Michael and Susan Gumz in Marathon County Circuit Court, Wisconsin, alleging that electricity supplied by NSP-Wisconsin harmed their dairy herd and caused them personal injury. The Gumz’s complaint alleges negligence, strict liability, nuisance, trespass, and statutory violations and seeks compensatory, punitive and treble damages. The complaint does not specify the amount of damages sought by the plaintiffs.
