Notes to Condensed Consolidated Financial Statements

(unaudited)

(Reference is made to Notes to Consolidated Financial Statements

included in the Company’s 2004 Annual Report on Form 10-K)

(1)	MANAGEMENT’S STATEMENT

The financial statements included herein have been prepared by Black Hills Corporation (the Company) without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations; however, the Company believes that the footnotes adequately disclose the information presented. These financial statements should be read in conjunction with the financial statements and the notes thereto, included in the Company’s 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission.

Accounting methods historically employed require certain estimates as of interim dates. The information furnished in the accompanying financial statements reflects all adjustments which are, in the opinion of management, necessary for a fair presentation of the June 30, 2005, December 31, 2004 and June 30, 2004 financial information and are of a normal recurring nature. The results of operations for the three and six months ended June 30, 2005, are not necessarily indicative of the results to be expected for the full year. All earnings per share amounts discussed refer to diluted earnings per share unless otherwise noted.

(2)	RECLASSIFICATIONS

Certain 2004 amounts in the financial statements have been reclassified to conform to the 2005 presentation. These reclassifications did not have an effect on the Company’s total stockholders’ equity or net income available for common stock as previously reported.

(3)	STOCK-BASED COMPENSATION

At June 30, 2005, the Company had one stock-based employee compensation plan under which it can grant stock options to its employees and two prior plans with stock options outstanding. The Company accounts for these plans under the recognition and measurement principles of Accounting Principles Board (APB) Opinion No. 25, “Accounting for Stock Issued to Employees (APB 25),” and related interpretations. No employee compensation cost related to stock options is reflected in net income, as all options granted under these plans had an exercise price equal to the market value of the underlying common stock on the date of grant.

The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of Statement of Financial Accounting Standards (SFAS) No. 123, “Accounting for Stock-Based Compensation (SFAS 123),” to stock-based employee compensation (in thousands, except per share amounts):

(4)	RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

SFAS No. 123 (Revised 2004)

In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 123 (Revised 2004) “Share Based Payment” (SFAS 123 (Revised 2004)). SFAS 123 (Revised 2004) requires the measurement and recognition of the cost of employee services received in exchange for an award of equity instruments, based on the grant-date fair value of the award. The cost is to be recognized over the requisite service period. In April 2005, the Securities and Exchange Commission (SEC) adopted a final rule amending the effective date of SFAS 123 (Revised 2004) to the first interim or annual reporting period of the fiscal year beginning after June 15, 2005. The Company currently accounts for its employee equity compensation stock option plans under the provisions of APB No. 25 and no stock-based employee compensation cost is reflected in net income (see Note 3, Stock-Based Compensation). The effect of adoption of SFAS 123 (Revised 2004) will be to recognize compensation expense for the fair value of the stock options granted at the grant date. Total stock-based employee compensation expense, net of related tax effects, would have been $0.1 million for the three month periods ending June 30, 2005 and 2004, and $0.3 million for the six month periods ending June 30, 2005 and 2004, had the Company applied the fair value recognition provisions of SFAS 123 during those periods.

FIN 47

In March 2005 the FASB issued FIN 47, “Accounting for Conditional Asset Retirement Obligations.” This interpretation clarifies that the term conditional asset retirement obligation as used in FASB Statement No. 143, “Accounting for Asset Retirement Obligations,” (SFAS 143) refers to a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. The obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and (or) method of settlement. Thus, the timing and (or) method of settlement may be conditional on a future event. Accordingly, an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability can be reasonably estimated. The fair value of a liability for the conditional asset retirement obligation should be recognized when incurred – generally upon acquisition, construction, or development and (or) through the normal operation of the asset. Uncertainty about the timing and (or) method of settlement of a conditional asset retirement obligation should be factored into the measurement of the liability when sufficient information exists.

The Company has identified legal retirement obligations related to plugging and abandonment of natural gas and oil wells in its Oil and gas segment and reclamation of its coal mining sites in its Coal mining segment. FIN 47 is effective for fiscal years ending after December 15, 2005. The Company is currently evaluating the effect of FIN 47 on the Company’s consolidated results of operations, financial position and cash flows.

EITF Issue No. 04-6

On March 17, 2005, the Emerging Issues Task Force (EITF) issued EITF Issue No. 04-6, “Accounting for Stripping Costs Incurred during Production in the Mining Industry” (EITF 04-6). EITF 04-6 provides that stripping costs incurred during the production phase of a mine are variable production costs that should be included in the costs of the inventory produced during the period that the stripping costs are incurred. EITF 04-6 is effective for the first reporting period in fiscal years beginning after December 15, 2005. The Company does not believe the adoption of EITF 04-6 will have a material impact on the Company’s consolidated results of operations, financial position and cash flows.

Proposed Accounting Rules for Uncertain Tax Positions

On July 14, 2005, the FASB published an Exposure Draft of a proposed Interpretation, “Accounting for Uncertain Tax Positions”. The Exposure Draft would apply to all tax positions accounted for in accordance with FASB Statement No. 109, “Accounting for Income Taxes” and would establish specific criteria that must be met for benefits of an uncertain tax position to be recognized in the financial statements. Management is currently evaluating the potential impact the proposed Interpretation would have on the Company’s consolidated financial statements and will monitor the FASB’s progress towards finalizing this Exposure Draft. The Exposure draft proposes an effective date of the close of the first fiscal year ending after December 15, 2005 with the impact of adoption to be reported as a cumulative effect of an accounting change.

(7)	RECOVERED/RECOVERABLE PURCHASED ELECTRIC AND GAS ENERGY COSTS –

NET

The Company’s electric and gas subsidiary, Cheyenne Light, Fuel & Power (CLF&P), recovers purchased power and natural gas costs from customers through an electric cost adjustment (ECA) and gas cost adjustment (GCA) mechanism. Each year CLF&P files with the Wyoming Public Service Commission (WPSC) an ECA, effective January 1, and a GCA, effective October 1, to be included in tariff rates for that following year. The ECA and GCA are based on forecasts of the upcoming year’s energy costs and recovery of prior year unrecovered costs. To the extent that energy costs are under recovered or over recovered during the year, they are recorded as a regulatory deferred asset or liability, respectively. These deferred energy balances are interest bearing. As of June 30, 2005, the Company had a deferred energy asset balance of approximately $6.0 million, which is included in “Other” under “Other assets” on the accompanying Condensed Consolidated Balance Sheet.

(8)	EARNINGS PER SHARE

Basic earnings per share from continuing operations is computed by dividing income from continuing operations by the weighted-average number of common shares outstanding during the period. Diluted earnings per share from continuing operations gives effect to all dilutive common shares potentially outstanding during a period. A reconciliation of “Income from continuing operations” and basic and diluted share amounts is as follows (in thousands):

Period ended June 30, 2005	Three Months			Six Months

(10)	CHANGES IN COMMON STOCK

Other than the following transactions, the Company has no other material changes in its common stock, as reported in Note 10 of the Notes to Consolidated Financial Statements in the Company’s 2004 Annual Report on Form 10-K.

• Effective January 1, 2005, the Company adopted a performance share award plan in which certain officers of the Company are participants. Performance shares are awarded based on the Company’s total shareholder return over designated performance periods as measured against a selected peer group. In addition, the Company’s stock price must also increase during the performance periods. Target grants of 41,499 performance shares were made for the January 1, 2005 through December 31, 2007 performance period.

Participants may earn additional performance shares if the Company’s total shareholder return exceeds the 50^th percentile of the selected peer group. The final value of the performance shares will vary according to the number of shares of common stock that are ultimately granted based upon the actual level of attainment of the performance criteria. The performance awards are paid 50 percent in the form of cash and 50 percent in the form of common stock.

Grants under this performance share plan are in addition to grants under two other performance share plans awarded March 1, 2004. Compensation expense recognized for all of the performance share awards for the three and six months ended June 30, 2005 was $0.6 million and $0.9 million, respectively.

• The Company granted 14,400 stock options at a weighted-average exercise price of $30.71 per share.

• 205,678 stock options were exercised at a weighted-average price of $23.61 per share.

• The Company acquired 11,964 shares of treasury stock related to the share withholding provisions of the Restricted Stock Plan for the payment of taxes associated with the vesting of shares of restricted stock for certain officers and key employees.

• The Company granted 42,913 restricted common shares and 2,594 restricted stock units during the first six months of 2005. The pre-tax compensation cost related to the awards of restricted stock and restricted stock units of approximately $1.4 million will be recognized over the three-year vesting period.

• The Company issued 9,557 shares as a payout of Board of Directors Common Stock Equivalents upon a director’s retirement.

(11)	CHANGES IN LONG-TERM DEBT

On January 21, 2005, the Company acquired CLF&P from Xcel Energy Inc. Included in the purchase price of CLF&P was the assumption of $24.6 million in long-term debt consisting of First Mortgage Bonds. The debt consists of $7.0 million of variable rate Industrial Development Revenue Bonds due in 2021, $10.0 million variable rate Industrial Development Revenue Bonds due 2027 and $7.6 million 7.5 percent Bonds due 2024. Substantially all properties of CLF&P are subject to the liens securing the First Mortgage Bonds. Annual maturities on the First Mortgage Bonds for the next five years are $0.2 million a year.

In June 2005, the Company repaid $81.5 million of long-term debt (including current maturities) outstanding on the project level financing at our Fountain Valley facility. Upon repayment of the debt, the Company expensed approximately $0.4 million of associated, unamortized deferred financing costs and approximately $0.3 million related to an interest rate swap previously designated as a cash flow hedge of this debt.

(14)	SUMMARY OF INFORMATION RELATING TO SEGMENTS OF THE COMPANY’S BUSINESS

The Company’s reportable segments are those that are based on the Company’s method of internal reporting, which generally segregates the strategic business groups due to differences in products, services and regulation. As of June 30, 2005, substantially all of the Company’s operations and assets are located within the United States. On June 30, 2005, the Company completed the sale of its subsidiary, Black Hills FiberSystems, Inc., which operated as the Company’s Communications segment (see Note 18). The financial information of the Communications segment has been reclassified into Discontinued operations on the accompanying condensed consolidated financial statements. With the sale of the communications segment, the Company now conducts its operations through the following six reporting segments: Wholesale Energy group consisting of the following segments: Coal mining, which engages in the mining and sale of coal from its mine near Gillette, Wyoming; Oil and gas, which produces, explores and operates oil and gas interests located in the Rocky Mountain region, Texas, California and other states; Energy marketing and transportation, which markets natural gas, oil and related services to customers in the Midwest, Southwest, Rocky Mountain, West Coast and Northwest regions and transports crude oil in Texas; and Power generation, which produces and sells power and capacity to wholesale customers with plants concentrated in Colorado, Nevada, Wyoming and California; and Retail Services group consisting of the following segments: Electric utility, which supplies electric utility service to western South Dakota, northeastern Wyoming and southeastern Montana; and Electric and gas utility, acquired January 21, 2005, which supplies electric and gas utility service to Cheyenne, Wyoming and vicinity.

Segment information follows the same accounting policies as described in Note 23 of the Company’s 2004 Annual Report on Form 10-K. In accordance with the provisions of SFAS No. 71 “Accounting for the Effects of Certain Types of Regulation” (SFAS 71), intercompany fuel sales to the electric utility are not eliminated.

Derivatives and certain natural gas marketing activities were marked to fair value on June 30, 2005, December 31, 2004 and June 30, 2004, and the related gains and/or losses recognized in earnings. The amounts included in the accompanying Condensed Consolidated Balance Sheets and Statements of Income are as follows (in thousands):

	Current		Non-current		Current		Non-current
	Derivative		Derivative		Derivative		Derivative		Unrealized
	Assets		Assets		Liabilities		Liabilities		Gain (loss)

In addition, certain volumes of natural gas inventory have been designated as the underlying hedged item in a “fair value” hedge transaction. These volumes are stated at market value using published spot industry quotations. Market adjustments are recorded in inventory on the Balance Sheet and the related unrealized gain/loss on the Statement of Income. As of June 30, 2005, December 31, 2004 and June 30, 2004, the market adjustments recorded in inventory were $2.9 million, $(9.0) million and $0.1 million, respectively.

Activities Other Than Trading

Crude Oil Marketing

The contract or notional amounts and terms of our crude oil contracts, are set forth below:

	June 30, 2005		December 31, 2004		June 30, 2004
		Maximum		Maximum		Maximum
	Notional	Term in	Notional	Term in	Notional	Term in
(in thousands of barrels)	Amounts	Years	Amounts	Years	Amounts	Years

Crude oil purchased	1,919	0.75	1,669	1.0	2,622	0.5
Crude oil sold	1,878	0.75	1,651	1.0	2,679	0.5

The Company’s crude oil marketing contracts are accounted for under the accrual method of accounting. Settled contract amounts are reported in revenues on a gross basis in accordance with EITF Issue No. 99-19, “Reporting Revenue Gross as a Principal Versus Net as an Agent” (EITF 99-19) and established industry practice.

In 2004, the EITF initiated a review under EITF Issue No. 04-13, “Accounting for Purchases and Sales of Inventory with the Same Counterparty,” to determine if such transactions should be reported on a gross basis or a net basis. In its crude oil marketing activities, the Company uses a type of transaction commonly called a buy/sell, which generally consists of the purchase and sale of crude oil from the same counterparty. In a typical buy/sell transaction, Company A enters into a contract to sell a particular grade of crude oil at a specified location to Company B on a future date, and simultaneously agrees to buy from Company B a particular grade of crude oil at a different location at the same or another specified date.

The characteristics of buy/sell transactions include gross invoicing reflecting the quality and location differences of the crude oil and physical delivery requirements. Nonperformance by one party does not relieve the other party’s obligation to perform under the contract except for events of force majeure. The risks and rewards of ownership are evidenced by title transfer, assumption of environmental risk, transportation scheduling and counterparty credit risk. Because of these characteristics, the Company reports the sale of the barrels as gross revenues and the purchase of the barrels as gross purchases in accordance with EITF 99-19.

Some registrants in our industry may report buy/sell transactions on a net rather than a gross presentation. The EITF is reviewing these transactions to determine if more specific guidance is needed for determining a net rather than gross presentation in consolidated earnings. While a net presentation of this issue would reduce both the Company’s revenues and purchases, our net income would not be impacted.

Oil and Gas Exploration and Production

On June 30, 2005, December 31, 2004 and June 30, 2004, the Company had the following swaps and related balances (in thousands):

Based on June 30, 2005 market prices, a $5.2 million loss would be realized and reported in pre-tax earnings during the next twelve months related to hedges of production. These estimated realized losses for the next twelve months were calculated using June 30, 2005 market prices. Estimated and actual realized losses will likely change during the next twelve months as market prices change.

Financing Activities

On June 30, 2005, December 31, 2004 and June 30, 2004, the Company’s interest rate swaps and related balances were as follows (in thousands):

financing	$	113,000	4.48%	2.25	$	456	$	—	$	2,331	$	797	$	(2,672)	$	—

Based on June 30, 2005 market interest rates and balances, approximately $0.1 million would be realized and reported in pre-tax earnings as additional interest expense during the next twelve months. Estimated and realized amounts will likely change during the next twelve months as market interest rates change.

In June 2005, the Company repaid approximately $81.5 million of project level financing on its Fountain Valley power facility. The Company has an interest rate swap with a $25 million notional amount that was previously designated as a cash flow hedge of the variable rate interest payments on this project level debt. In accordance with FAS 133, upon repayment of the debt the Company re-designated the interest rate swap as a cash flow hedge and reclassified approximately $0.3 million from Accumulated Other Comprehensive Loss into earnings as additional interest expense. Without hedge designation, future variability in the fair value of this derivative will be recorded as a gain or loss in earnings.

(16)	LEGAL PROCEEDINGS

The Company is subject to various legal proceedings, claims and litigation as described in Note 21 of the Notes to Consolidated Financial Statements in the Company’s 2004 Annual Report on Form 10-K. There have been no material developments in these proceedings or any new material proceedings that have developed or material proceedings that have terminated during the first six months of 2005.

(17)	ACQUISITION

On January 13, 2004, the Company entered into a Stock Purchase Agreement to acquire from Xcel Energy, Inc. all of the outstanding capital stock of its subsidiary, CLF&P. On January 21, 2005, the Company completed this acquisition. The Company purchased all the common stock of CLF&P, including the assumption of outstanding debt of approximately $24.6 million, for approximately $90.7 million. The purchase price has been revised by approximately $(2.2) million to reflect a recent revision to the estimated working capital adjustment included in the purchase payment on the date of the transaction closing.

This acquisition has been accounted for under the purchase method of accounting, and accordingly, the purchase price has been allocated to the acquired assets and liabilities based on preliminary estimates of the fair values of the assets purchased and liabilities assumed as of the date of acquisition. The estimated purchase price allocations are subject to adjustment, generally within one year of the date of acquisition. Allocation of the purchase price (as revised for the working capital adjustment described above) is as follows (in thousands):

Current assets	$	18,353
Property, plant and equipment		99,275
Deferred assets		16,224
	$	133,852

Current liabilities	$	12,761
Long-term debt		26,388

Sale of Pepperell Plant

During the third quarter of 2003, the Company adopted a plan to sell the 40 megawatt gas-fired Pepperell plant. On April 8, 2005, the Company sold the Pepperell plant to an unrelated party, Pepperell Realty LLC for a nominal amount plus the assumption of certain obligations. The sale of this facility was considered an asset sale and the Company retained the deferred tax asset, which was originally classified into Discontinued operations. For business segment reporting purposes, the Pepperell plant results were previously included in the Power generation segment.

ITEM 2.

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

We are a diversified energy holding company operating principally in the United States with two major business groups – wholesale energy and retail services. We report our business groups in the following segments:

Business Group	Financial Segment

Wholesale energy group	Power generation
	Oil and gas
	Coal mining
	Energy marketing and transportation

Retail services group	Electric utility
	Electric and gas utility

Our wholesale energy group, Black Hills Energy, Inc., engages in the production of electric power through ownership of a diversified portfolio of generating plants and the sale of electric power and capacity primarily under long-term contracts, the production of coal, natural gas and crude oil primarily in the Rocky Mountain region, and the marketing and transportation of fuel products. Our retail services group consists of our electric and gas utilities segments. Our electric utility generates, transmits and distributes electricity to an average of approximately 62,000 customers in South Dakota, Wyoming and Montana. Our electric and gas utility serves approximately 38,000 electric and 31,000 natural gas customers in Cheyenne, Wyoming and vicinity and was acquired on January 21, 2005.

In June 2005, we sold our subsidiary, Black Hills FiberSystems, Inc., previously reported as our Communications segment. In April 2005, we also sold our Pepperell power plant, our last remaining power plant in the eastern region and previously reported in our Power generation segment. In May 2004, we sold our subsidiary, Landrica Development Corp., which held some land and coal enhancement facilities that were previously reported in our Coal mining segment. Prior period results have been reclassified to present the financial information as Discontinued operations.

The following discussion should be read in conjunction with Item 7. – Management’s Discussion and Analysis of Financial Condition and Results of Operations – included in our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission.

Results of Operations

Consolidated Results

Revenue and Income (loss) from continuing operations provided by each business group and as a percentage of our total revenue and total income (loss) from continuing operations were as follows:

	Three Months Ended				Six Months Ended

	$16,040	100%	$9,721	100%	$32,792	100%	$21,499	100%

Discontinued operations in 2005 and 2004 represent the operations of our 40 megawatt Pepperell power plant, which was sold in April, 2005 and Black Hills FiberSystems, Inc., which was sold in June, 2005; and in 2004, represents the operations of Landrica Development Corp., which was sold on May 21, 2004.

Discontinued operations for the three and six months ended June 30, 2005 primarily represent operations and loss on sale of the Communications segment. Operations benefited from discontinuance of depreciation upon entering the definitive agreement to sell, but this reduced depreciation resulted in higher book value than originally anticipated and consequently resulted in a higher after-tax loss on sale than originally estimated. After-tax loss on sale was $4.7 million, or $0.14 per share. See Note 18 of Notes to Condensed Consolidated Financial Statements for further description of our discontinued operations.

On January 21, 2005, we completed the acquisition of Cheyenne Light, Fuel & Power Company (CLF&P), an electric and natural gas utility serving customers in Cheyenne, Wyoming and vicinity. The Company purchased all of the common stock of CLF&P, including the assumption of outstanding debt of approximately $24.6 million, for approximately $91 million. The results of operations of CLF&P have been included in the accompanying Condensed Consolidated Financial Statements from the date of acquisition.

In July 2005, the electric utility experienced an unscheduled outage at its 90 megawatt Neil Simpson II power plant. That plant is expected to be out of service for the month of August. To meet our forecasted needs, we have obtained supplemental purchased power and additional natural gas supplies, which will affect third quarter 2005 financial results. The economic impact of this outage is expected to be in the range of $2.5 million to $3.0 million pre-tax, taking into account increased fuel costs, higher purchased power expenses and reduced coal sales.

Three Months Ended June 30, 2005 Compared to Three Months Ended June 30, 2004. Revenues for the three months ended June 30, 2005 increased 15 percent, or $40.5 million, compared to the same period in 2004. Increased revenues were primarily the result of the acquisition and consolidation of CLF&P and higher revenues from oil and gas sales as a result of increased production and higher prices received.

Operating expenses increased 14 percent, or $32.9 million, primarily resulting from the cost of operations of CLF&P, and higher depletion and production and severance taxes at our oil and gas segment and increased corporate costs from higher compensation expense and professional fees.

Income from continuing operations increased 65 percent or $6.3 million due primarily to the following:

• a $1.1 million increase in Energy marketing and transportation earnings;

• a $0.9 million increase in Power generation earnings;

• a $3.5 million increase in Oil and gas earnings;

• a $1.6 million increase in Electric utility earnings; offset by

• a $1.8 million increase in corporate costs.

See the following discussion of our business segments for more detail on our results of operations.

Six Months Ended June 30, 2005 Compared to Six Months Ended June 30, 2004. Revenues for the six months ended June 30, 2005 increased 13 percent, or $70.7 million, compared to the same period in 2004. Increased revenues are primarily due to the acquisition and consolidation of CLF&P and a 41 percent increase in revenues at our oil and gas segment.

Operating expenses increased 12 percent, or $57.7 million, primarily due to the cost of operations of CLF&P, increased power costs at our Electric utility and increased administrative and general costs due to increased compensation expense and professional fees. In addition, a $1.0 million pre-tax gain on the sale of assets was recorded as an offset to general and administrative expense in the first quarter of 2004. The gain on sale of assets is included in the 2004 “Corporate” results.

Income from continuing operations increased 53 percent, or $11.3 million, primarily due to the following:

• a $6.8 million increase in Power generation earnings;

• a $4.8 million increase in Oil and gas earnings;

• a $0.9 million increase in Electric utility earnings; offset by

• a $2.5 million increase in corporate costs.

See the following discussion of our business segments for more detail on our results of operations.

A discussion of results of operations from our operating segments is included in the following pages.

The following segment information does not include intercompany eliminations or discontinued operations. Accordingly, 2004 information has been revised as necessary to reclassify information related to operations that were discontinued.

The following is a summary of average daily energy marketing volumes:

	Three Months Ended		Six Months Ended
	June 30		June 30
	2005	2004	2005	2004

Natural gas physical sales – MMbtus	1,562,600	1,040,000	1,460,700	1,126,700
Natural gas financial sales - MMbtus	742,200	512,800	708,700	450,400
Crude oil – barrels	35,700	51,000	35,600	50,600

Three Months Ended June 30, 2005 Compared to Three Months Ended June 30, 2004. Revenue increases from crude oil marketing were more than offset by a decrease in oil transportation revenues, due to the suspension of shipments for routine regulatory testing of the Millennium pipeline system in June 2005. Shipments of crude oil through the pipeline resumed early August 2005.

Income from continuing operations increased $1.1 million primarily due to a $3.4 million unrealized mark-to-market gain for the quarter ended June 30, 2005, compared to a $0.1 million unrealized gain in the second quarter of 2004, resulting in a quarter-over-quarter, pre-tax increase of $3.3 million in unrealized mark-to-market adjustment at our gas marketing operations. (For discussion of potential volatility in energy marketing earnings related to accounting treatment of certain hedging activities at our natural gas marketing operations see “Trading Activities” in Part 1, Item 3 of this Form 10-Q.) These items were partially offset by a $1.6 million decrease in realized gas marketing margins received and lower oil marketing and transportation volumes.

Six Months Ended June 30, 2005 Compared to Six Months Ended June 30, 2004. Revenue decreases from crude oil marketing were more than offset by a decrease in the cost of crude oil sold, resulting in increased crude oil marketing margins. Oil transportation revenues decreased due to the suspension of shipments for routine regulatory testing of the Millennium pipeline system in June 2005. Shipments of crude oil through the pipeline resumed early August 2005.

Income from continuing operations remained flat with the prior year. A $0.3 million unrealized mark-to-market gain for the six months ended June 30, 2005, compared to a $0.2 million unrealized mark-to-market loss in the six months ended June 30, 2004, resulted in a year-over-year, pre-tax increase of $0.5 million in unrealized mark-to-market adjustments at our gas marketing operations. Realized gas marketing margins increased $0.1 million.

Three Months Ended June 30, 2005 Compared to Three Months Ended June 30, 2004. Revenues in the second quarter of 2005 decreased $0.2 million compared to revenues in the second quarter of 2004. Decreased revenues at our Las Vegas facility were partially offset by increased revenues at our Harbor facility, primarily due to a new three-year tolling agreement which commenced April 1, 2005.

Income from continuing operations increased $0.9 million. Increased earnings were the result of increased income from equity investments due to the impact of mark-to-market adjustments at certain power fund investments that use a fair value method of accounting, partially offset by increased interest expense primarily related to a $0.7 million charge for the write-off of certain deferred costs associated with the project financing debt repaid during the quarter.

Six Months Ended June 30, 2005 Compared to Six Months Ended June 30, 2004. Revenues increased 4 percent in the six months ended June 30, 2005 compared to the same period in 2004. The increased revenues are primarily attributable to increased revenues at our Las Vegas II and Harbor facilities. In the first six months of 2005, our Las Vegas II facility sold capacity and energy to Nevada Power Company under a long-term tolling arrangement, which became effective April 1, 2004, as opposed to selling power into the market on a merchant basis for the first three months of 2004, when economic to do so. Revenues from our Harbor facility increased due to a new three-year tolling agreement, which commenced April 1, 2005.

Income from continuing operations increased $6.8 million. Increased earnings were the result of higher revenues and increased income from equity investments due to the impact of mark-to-market adjustments at certain power fund investments that use a fair value method of accounting, partially offset by increased interest expense related to a $0.7 million charge for the write-off of certain deferred costs associated with the project financing debt repaid during the second quarter of 2005. In addition, the Las Vegas II facility incurred fuel costs in the first three months of 2004, before the new, long-term tolling arrangement took effect.

Mcf equivalent sales	3,443,600	2,939,300	6,908,200	6,019,500

Three Months Ended June 30, 2005 Compared to Three Months Ended June 30, 2004. Revenue from oil and gas increased 79 percent for the three months ended June 30, 2005 compared to the three months ended June 30, 2004. Gas volumes sold increased 27 percent primarily due to increased production from recently completed wells, and oil volumes sold decreased 13 percent primarily due to a normal decline in our mature Wyoming oil field and reduced opportunities for enhanced oil recovery activities. Average gas and oil prices received, net of hedges, in the three months ended June 30, 2005 were $5.58/Mcf and $32.87/bbl, respectively, compared to $4.23/Mcf and $23.67/bbl, respectively, in the same period of 2004.

Total operating expenses increased 30 percent primarily due to increased production expenses related to the additional sales volumes. The 2005 lease operating expenses per Mcfe sold (LOE/MCFE) for the three month period increased 8 percent from $0.95/Mcfe in 2004 to $1.03/Mcfe in 2005 due to increased production activities in the second quarter of 2005. In addition, the second quarter of 2005 included workover and other LOE activities which were delayed from the first three months of 2005 due to inclement weather conditions. Depletion expense per Mcfe increased 39 percent over the prior year from $0.84/Mcfe in 2004 to $1.17/Mcfe in 2005. This increase is primarily a function of increases in average development costs per Mcfe as we develop existing fields. In addition, quarterly differences in depletion rates are influenced by the timing of additions to our cost pool when compared to the prior year.

Six Months Ended June 30, 2005 Compared to Six Months Ended June 30, 2004. Revenues from oil and gas increased 41 percent for the six months ended June 30, 2005 compared to the six months ended June 30, 2004. Gas volumes sold increased 24 percent due to increased production from recently completed wells, and oil volumes sold decreased 14 percent primarily due to a normal decline in our mature Wyoming oil field and reduced opportunities for enhanced oil recovery activities. Average gas and oil prices received, net of hedges, in the six months ended June 30, 2005 were $5.47/Mcf and $32.80/bbl, respectively, compared to $4.30/Mcf and $24.46/bbl, respectively, in the same period of 2004.

Total operating expenses increased 19 percent primarily due to increased production expenses related to the additional sales volumes. The 2005 lease operating expenses per Mcfe sold (LOE/MCFE) for the six month period decreased 3 percent from $0.95/Mcfe in 2004 to $0.92/Mcfe in 2005 due to production efficiencies realized from an increase in productive wells placed in service. Depletion expense per Mcfe increased 19 percent over the prior year from $0.91/Mcfe in 2004 to $1.08/Mcfe in 2005. This increase is primarily a function of increases in average development costs per Mcfe as we develop existing fields.

Three Months Ended June 30, 2005 Compared to Three Months Ended June 30, 2004. Revenue from our coal mining segment increased 11 percent for the three month period ended June 30, 2005, compared to the same period in 2004. The increase in revenue was primarily attributable to increased production in 2005 relative to temporarily lower production levels caused by scheduled and unscheduled plant outages in the second quarter of 2004. The Wyodak plant, operated by PacifiCorp, has postponed a planned 2005 major maintenance outage and rescheduled the outage for 2006.

Operating expenses increased 5 percent or approximately $0.3 million, primarily due to increased production costs partially offset by lower depletion rates.

Income from continuing operations increased 27 percent primarily due to the increase in revenues and lower depletion costs, partially offset by increased production-related costs.

Six Months Ended June 30, 2005 Compared to Six Months Ended June 30, 2004. Revenue from our coal mining segment increased 1 percent for the six month period ended June 30, 2005 compared to the same period in 2004. Tons sold in the six month period ended June 30, 2005 increased 1 percent over the prior period. The Wyodak plant incurred unscheduled outages during the first three months of 2005.

Operating expenses decreased 1 percent for the six month period ended June 30, 2005 compared to 2004. Increased compensation and production costs were offset by lower depletion rates.

Income from continuing operations increased 3 percent due to the increase in revenues and lower depletion costs, partially offset by increased compensation and production costs.

Three Months Ended June 30, 2005 Compared to Three Months Ended June 30, 2004. Electric utility revenues increased 6 percent for the three month period ended June 30, 2005, compared to the same period in the prior year. Firm commercial, residential, industrial and contract wholesale sales increased 6 percent, 9 percent, 1 percent and 12 percent, respectively. Wholesale off-system sales increased 5 percent with a 12 percent increase in average price received, partially offset by a 6 percent decrease in megawatt-hours sold. Cooling degree days, which is a measure of weather trends, were 151 percent higher than the same period in the prior year.

Electric operating expenses increased 3 percent for the three month period ended June 30, 2005, compared to the same period in the prior year. Higher operating expenses were primarily the result of a $0.6 million increase in fuel and purchased power costs. The increase in fuel and purchased power was due to a $0.4 million increase in purchased power, resulting from a 12 percent increase in average price per megawatt-hour partially offset by an 8 percent decrease in megawatt-hours purchased, and a $0.2 million increase in fuel costs due to a 14 percent increase in megawatt-hours generated partially offset by a 7 percent decrease in average cost. Megawatt hours produced through coal-fired generation increased in the three months ended June 30, 2005 as we incurred scheduled and unscheduled plant outages during the second quarter of 2004. Prevailing gas prices have made it more economical for us to purchase power for our peaking needs rather than generate energy from our gas turbines. The increase in operating expense was also affected by increased legal expense and compensation costs, partially offset by lower maintenance costs.

Income from continuing operations increased $1.6 million primarily due to increased revenues, lower maintenance costs and lower interest expense, due to the pay down of debt, partially offset by increased fuel and purchased power costs, legal expense and compensation costs.

Six Months Ended June 30, 2005 Compared to Six Months Ended June 30, 2004. Electric utility revenues increased 5 percent for the six month period ended June 30, 2005 compared to the same period in the prior year. Firm commercial, residential and contract wholesale sales increased 4 percent, 5 percent and 6 percent, respectively. Wholesale off-system sales increased 15 percent due to an 11 percent increase in average price received and a 4 percent increase in megawatt-hours sold. Cooling degree days for the six month period were 151 percent higher than the same period in 2004 and heating degree days were 3 percent lower than the same period in 2004.

Electric operating expenses increased 7 percent for the six month period ended June 30, 2005, compared to the same period in the prior year. Higher operating expenses were primarily the result of a $3.0 million increase in fuel and purchased power costs. The increase in fuel and purchased power was due to a $3.1 million increase in purchased power, resulting from a 12 percent increase in average price per megawatt-hour and a 3 percent increase in megawatt-hours purchased, offset by a nominal decrease in fuel costs due to a 6 percent decrease in average costs partially offset by a 4 percent increase in megawatt-hours generated. Megawatt hours produced through coal-fired generation increased in the six months ended June 30, 2005 as we incurred scheduled and unscheduled plant outages during the second quarter of 2004. Prevailing gas prices have made it more economical for us to purchase power for our peaking needs and increased off-system sales rather than generate energy from our gas turbines. The increase in operating expense was also affected by increased legal expense and compensation costs, partially offset by lower maintenance costs.

Income from continuing operations increased $0.9 million primarily due to increased revenues, lower maintenance costs and lower interest expense, due to the pay down of debt, partially offset by increased fuel and purchased power costs, legal expense and compensation costs.

Other Event

In July 2005, the electric utility experienced an unscheduled outage at its 90 megawatt Neil Simpson II power plant. That plant is expected to be out of service for the month of August. To meet our forecasted needs, we have obtained supplemental purchased power and additional natural gas supplies, which will negatively affect third quarter 2005 financial results. The economic impact of this outage is expected to be in the range of $2.5 million to $3.0 million pre-tax, taking into account increased fuel costs, higher purchased power expenses and reduced coal sales.

For the three month period ended June 30, 2005, natural gas sales comprised 32 percent or $8.7 million of total revenues, and electric sales comprised 68 percent or $18.8 million of total revenues for this segment. Results for the period included revenues of approximately $0.5 million for billing adjustments primarily related to pre-acquisition periods.

For the period January 21, 2005 through June 30, 2005, natural gas sales comprised 36 percent, or $19.7 million of total revenues and electric sales comprised 64 percent, or $34.8 million of total revenues. Results for the period included revenues of approximately $0.5 million for billing adjustments primarily related to pre-acquisition periods.

The following table provides certain operating statistics:

	Three Months Ended	January 21, 2005 to
	June 30	June 30
	2005	2005

Electric sales – MWh	251,550	428,650
Gas sales – Dth	1,010,900	2,347,700

On April 18, 2005, applications were filed with the Wyoming Public Service Commission (WPSC) to increase the base rates for retail electric and natural gas service effective January 1, 2006. The applications request a 3.94 percent and 5.62 percent increase in electric and gas revenues, respectively. We expect that these increases, if approved by the WPSC, would result in an annual revenue increase of approximately $5.2 million. In addition, we expect additional costs in 2006 related to allocated corporate costs and increased costs for operational projects to total approximately $1.5 million.

We are progressing with our plans to build Wygen II, a 90 megawatt, coal-fired power plant to be sited at our Wyodak energy complex near Gillette, Wyoming. Wygen II would be a regulated asset of CLF&P. The cost of construction is estimated to be approximately $169 million. Several permits are required before construction can commence, and to date, we have been successful in obtaining an air quality permit and an industrial siting permit from the Wyoming Department of Environmental Quality. We expect to obtain the final permit, a Certificate of Public Convenience and Necessity, from the Wyoming Public Service Commission around September 1, 2005. Upon receipt of permits, we would begin construction yet this year. Wygen II is expected to commence commercial operations in early 2008.

Corporate

Losses from corporate activities primarily represent unallocated corporate costs. Higher losses are primarily the result of increases in accrued incentive compensation, in anticipation of achieving certain incentive plan goals, of approximately $1.3 million and $1.9 million, for the three and six month periods ended June 30, 2005, respectively, and increases in professional fees of approximately $0.8 million and $1.1 million for the three and six month periods ended June 30, 2005, respectively, primarily related to project development costs.

Critical Accounting Policies

There have been no material changes in our critical accounting policies from those reported in our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission. For more information on our critical accounting policies, see Part II, Item 7 of our 2004 Annual Report on Form 10-K.

Liquidity and Capital Resources

Cash Flow Activities

During the six-month period ended June 30, 2005, we generated sufficient cash flow from operations to meet our operating needs, to pay dividends on common and preferred stock, to pay our long-term debt maturities, and to fund our property, plant and equipment additions. We plan to fund future property and investment additions primarily through a combination of operating cash flow and increased short-term and long-term debt.

Cash flows from operations increased $76.4 million for the six-month period ended June 30, 2005 compared to the same period in the prior year primarily due to a $9.4 million increase in net income, an $11.7 million increase in our cash flows from net derivative assets and liabilities and a $54.8 million increase in operating assets and liabilities.

During the six months ended June 30, 2005, we had cash outflows from investing activities of $23.0 million, which was primarily related to property, plant and equipment additions in the normal course of business and the $67.3 million cash payment related to the acquisition of CLF&P, offset by a $103.0 million cash payment received for the sale of Black Hills FiberSystems.

During the six months ended June 30, 2005, we had cash outflows from financing activities of $116.0 million, primarily due to the repayment of $81.5 million of project level debt at our Fountain Valley facility and due to the payment of quarterly cash dividends on common stock and a decrease in short term borrowings.

Dividends

Dividends paid on our common stock totaled $20.9 million during the six months ended June 30, 2005, or $0.32 per share, per quarter in the first and second quarters of 2005. This reflects a 3.2 percent increase, as approved by our board of directors in January 2005, from the 2004 quarterly dividend level. The determination of the amount of future cash dividends, if any, to be declared and paid will depend upon, among other things, our financial condition, funds from operations, the level of our capital expenditures, restrictions under PUHCA, restrictions under our credit facilities and our future business prospects.

Short-Term Liquidity and Financing Transactions

Our principal sources of short-term liquidity are our revolving bank facility and cash provided by operations. Our liquidity position remained strong during the first six months of 2005. As of June 30, 2005, we had approximately $60.6 million of cash unrestricted for operations and $400 million of credit through revolving bank facilities. Approximately $12.1 million of the cash balance at June 30, 2005 was restricted by subsidiary debt agreements that limit our subsidiaries’ ability to dividend cash to the parent company.

Our revolving credit facility can be used to fund our working capital needs, for general corporate purposes, and to provide liquidity for a commercial paper program if implemented. At June 30, 2005, we had $13.0 million of borrowings outstanding under these facilities. After inclusion of applicable letters of credit, the remaining borrowing capacity under the bank facilities was $335.0 million at June 30, 2005.

On May 5, 2005, we entered into a new $400 million revolving bank facility with ABN AMRO as Administrative Agent, Union Bank of California and US Bank as Co-Syndication Agents, Bank of America and Harris Nesbitt as Co-Documentation Agents, and other syndication participants. The new facility has a five year term, expiring May 4, 2010. The facility contains a provision which allows the facility size to be increased by up to an additional $100 million through the addition of new lenders, or through increased commitments from existing lenders, but only with the consent of such lenders. The cost of borrowings or letters of credit issued under the new facility is determined based on our credit ratings; at our current ratings levels, the facility has an annual facility fee of 17.5 basis points, and has a borrowing spread of 70.0 basis points over the LIBOR (which equates to a 4.04 percent one-month borrowing rate as of June 30, 2005). In conjunction with entering into the new revolving bank facility, we terminated our $125 million revolving bank facility due May 12, 2005 and our $225 million facility due August 20, 2006.

The bank facility includes customary affirmative and negative covenants, such as limitations on the creation of new indebtedness and on certain liens, restrictions on certain transactions and maintenance of the following financial covenants:

• a consolidated net worth in an amount of not less than the sum of $625 million and 50 percent of our aggregate consolidated net income beginning January 1, 2005;

• a recourse leverage ratio not to exceed 0.65 to 1.00; and

• an interest coverage ratio of not less than 2.5 to 1.0.

If these covenants are violated, it would be considered an event of default entitling the lender to terminate the remaining commitment and accelerate all principal and interest outstanding.

A default under the bank facility may be triggered by events such as a failure to comply with financial covenants or certain other covenants under the bank facility, a failure to make payments when due or a failure to make payments when due in respect of, or a failure to perform obligations relating to, debt obligations of $20 million or more. A default under the bank facility would permit the participating banks to restrict the Company’s ability to further access the credit facility for loans or new letters of credit, require the immediate repayment of any outstanding loans with interest and require the cash collateralization of outstanding letter of credit obligations.

The bank facility prohibits the Company from paying cash dividends unless no default or no event of default exists prior to, or would result after, giving effect to such action.

Our consolidated net worth was $750.6 million at June 30, 2005, which was approximately $110.3 million in excess of the net worth we were required to maintain under the bank facilities in place at June 30, 2005. The long-term debt component of our capital structure at June 30, 2005 was 47.3 percent, our total debt leverage (long-term debt and short-term debt) was 48.2 percent, and our recourse leverage ratio was approximately 46.6 percent.

In addition, Enserco Energy Inc., our gas marketing unit, has a $150 million uncommitted, discretionary line of credit to provide support for the purchase of natural gas. As of June 30, 2005, we had a $3.0 million guarantee to the lender under this facility. At June 30, 2005, there were outstanding letters of credit issued under the facility of $114.5 million, with no borrowing balances outstanding on the facility.

Similarly, Black Hills Energy Resources, Inc. (BHER), our oil marketing unit, has an uncommitted, discretionary credit facility. The facility allows BHER to elect from $25 million up to $40 million of available credit via notification to the bank at the beginning of each calendar quarter. This line of credit provides credit support for the purchases of crude oil by BHER. We provided no guarantee to the lender under this facility. At June 30, 2005, BHER had elected to have $40.0 million of available credit and had letters of credit outstanding of $24.8 million.

There were no changes in our corporate credit ratings during the first six months of 2005; in June 2005, Moody’s revised the outlook on our ratings from negative to stable.

Our ability to obtain additional financing, if necessary, will depend upon a number of factors, including our future performance and financial results, and capital market conditions. We can provide no assurance that we will be able to raise additional capital on reasonable terms or at all.

There have been no material changes in our forecasted liquidity requirements from those reported in Item 7 of our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission.

Guarantees

During the first quarter of 2005, a $0.5 million guarantee related to payments under various transactions with Idaho Power Company was reduced to $0.3 million. During the second quarter of 2005, a $0.8 million guarantee related to payments under various transactions with Southern California Edison Company expired and was not renewed. At June 30, 2005, we had guarantees totaling $182.2 million in place.

Capital Requirements

During the six months ended June 30, 2005, capital expenditures were approximately $63.8 million for property, plant and equipment additions and $67.3 million for the acquisition of CLF&P (exclusive of debt assumed). We currently expect capital expenditures for the entire year 2005 to approximate $200 million, as detailed in Item 7 of our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission excluding debt assumed in the CLF&P acquisition and the elimination of capital expenditures related to the discontinued Communications segment.

We continue to actively evaluate potential future acquisitions and other growth opportunities in accordance with our disclosed business strategy. We are not obligated to a project until a definitive agreement is entered into and cannot guarantee we will be successful on any potential projects. Future projects are dependent upon the availability of economic opportunities and, as a result, actual expenditures may vary significantly from forecasted estimates.

RISK FACTORS

Other than as set forth below, there have been no material changes in our Risk Factors from those reported in Items 1 and 2 of our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission, which we incorporate by reference herein.

Our utilities may not raise their retail rates without prior approval of the South Dakota Public Utilities Commission (SDPUC) or the Wyoming Public Services Commission (WPSC). Any delays in obtaining approvals or having cost recovery disallowed in such rate proceedings could have an adverse effect on our revenues and results of operation.

The rate freeze agreement with the SDPUC for our Black Hills Power electric utility expired on January 1, 2005. Until such time as we petition the SDPUC or the WPSC for rate relief, or either commission requests a rate review, Black Hills Power may not increase its retail rates. Additionally, Black Hills Power may not invoke any fuel and purchased power adjustment tariff that would take effect prior to the completion of a rate proceeding, absent extraordinary circumstances. Because our utilities are generally unable to increase their base rates without prior approval from the SDPUC and the WPSC, our returns could be threatened by plant outages, machinery failure, increases in fuel and purchased power costs over which our utilities have no control, acts of nature, acts of terrorism or other unexpected events that could cause operating costs to increase and operating margins to decline. Moreover, in the event of unexpected plant outages or machinery failures, Black Hills Power may be required to purchase replacement power in wholesale power markets at prices that exceed the rates it is permitted to charge its retail customers.

As part of the process for obtaining approval to acquire CLF&P, we agreed with the WPSC that CLF&P and Black Hills Power would not raise retail rates for their respective Wyoming customers prior to January 1, 2006. In consideration of such date, our CLF&P utility filed rate cases with the WPSC on April 18, 2005 with respect to its retail gas and electric rates, requesting 5.62% and 3.94% increases in such rates, respectively. In its review of the rate cases, the WPSC will consider, among other things, the return on common equity, overall rate of return, depreciation expenses and cost of capital for CLF&P. Any costs found by the WPSC that have not been prudently incurred would not be recoverable from CLF&P’s customers. Such a finding, among any other unfavorable rulings by the WPSC in these rate cases, could negatively affect our revenues and results of operations.

NEW ACCOUNTING PRONOUNCEMENTS

Other than the new pronouncements reported in our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission and those discussed in Note 4 of the Notes to Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q, there have been no new accounting pronouncements issued that when implemented would require us to either retroactively restate prior period financial statements or record a cumulative catch-up adjustment.

FUTURE ISSUES

Energy Policy Act of 2005

In July 2005, Congress passed the Energy Policy Act of 2005 (the Act) and on August 8, 2005 the President signed the act into law. The Act includes numerous provisions meant to increase domestic gas and oil supplies, improve energy system reliability, build new nuclear power plants and expand renewable energy sources. The legislation would also repeal the Public Utility Holding Company Act of 1935. We are currently evaluating the impact that the Act may have on our results of operations and financial condition.

SAFE HARBOR FOR FORWARD-LOOKING INFORMATION

This Quarterly Report on Form 10-Q includes “forward-looking statements” as defined by the Securities and Exchange Commission, or SEC. We make these forward-looking statements in reliance on the safe harbor protections provided under the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical facts, included in this Form 10-Q that address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements. These forward-looking statements are based on assumptions which we believe are reasonable based on current expectations and projections about future events and industry conditions and trends affecting our business. However, whether actual results and developments will conform to our expectations and predictions is subject to a number of risks and uncertainties that, among other things, could cause actual results to differ materially from those contained in the forward-looking statements, including the risk factors described in Items 1 and 2 of our 2004 Annual Report on Form 10-K and in Item 2 of Part I of this quarterly report on Form 10-Q filed with the SEC, and the following:

• The amount and timing of capital deployment in new investment opportunities or for the repurchase of debt or stock;

• The volumes of our production from oil and gas development properties, which may be dependent upon issuance by federal, state, and tribal governments, or agencies thereof, of drilling, environmental and other permits, and the availability of specialized contractors, work force, and equipment;

• The extent of our success in connecting natural gas supplies to gathering, processing and pipeline systems;

• Our ability to successfully integrate CLF&P into our operations;

• Unfavorable rulings in the rate cases filed by CLF&P with the WPSC and in the periodic applications to recover costs for fuel and purchased power;

• Changes in business and financial reporting practices arising from the repeal of the Public Utilities Holding Company Act and other provisions of the recently enacted Energy Policy Act of 2005;

• Our ability to remedy any deficiencies that may be identified in the periodic review of our internal controls;

• The timing and extent of changes in energy-related and commodity prices, interest rates, energy and commodity supply or volume, the cost of transportation of commodities, and demand for our services, all of which can affect our earnings, liquidity position and the underlying value of our assets;

• The timing and extent of scheduled and unscheduled outages of power generation facilities;

• General economic and political conditions, including tax rates or policies and inflation rates;

• Our use of derivative financial instruments to hedge commodity, currency exchange rate and interest rate risks;

• The creditworthiness of counterparties to trading and other transactions, and defaults on amounts due from counterparties;

• The amount of collateral required to be posted from time to time in our transactions;

• Changes in or compliance with laws and regulations, particularly those relating to taxation, safety and protection of the environment;

• Changes in state laws or regulations that could cause us to curtail our independent power production;

• Weather and other natural phenomena;

• Industry and market changes, including the impact of consolidations and changes in competition;

• The effect of accounting policies issued periodically by accounting standard-setting bodies;

• The cost and effects on our business, including insurance, resulting from terrorist actions or responses to such actions;

• Capital market conditions, which may affect our ability to raise capital on favorable terms;

• Price risk due to marketable securities held as investments in benefit plans;

• Obtaining adequate cost recovery for our retail operations through regulatory proceedings; and

• Other factors discussed from time to time in our other filings with the SEC.

New factors that could cause actual results to differ materially from those described in forward-looking statements emerge from time to time, and it is not possible for us to predict all such factors, or the extent to which any such factor or combination of factors may cause actual results to differ from those contained in any forward-looking statement. We assume no obligation to update publicly any such forward-looking statements, whether as a result of new information, future events, or otherwise.

ITEM 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Trading Activities

The following table provides a reconciliation of our activity in energy trading contracts that meet the definition of a derivative under SFAS 133 and that were marked-to-market during the six months ended June 30, 2005 (in thousands):

Total fair value of natural gas marketing positions marked-to-market at December 31, 2004	$	(930)^(a)

supplies and fuel		2,876		4,762		(9,012)

	$	(97)	$	(4,598)	$	(930)

On January 1, 2003, the Company adopted EITF 02-3. The adoption of EITF 02-3 resulted in certain energy trading activities no longer being accounted for at fair value, therefore, the above reconciliation does not present a complete picture of our overall portfolio of trading activities and our expected cash flows from those operations. EITF Issue No. 98-10 “Accounting for Contracts Involved in Energy Trading and Risk Management Activities” (EITF 98-10) was superseded by EITF 02-3 and allowed a broad interpretation of what constituted “trading activity” and hence what would be marked-to-market. EITF 02-3 took a much narrower view of what “trading activity” should be marked-to-market, limiting mark-to-market treatment primarily to only those contracts that meet the definition of a derivative under SFAS No. 133 “Accounting for Derivative Instruments and Hedging Activities” (SFAS 133). At our natural gas marketing operations, we often employ strategies that include derivative contracts along with inventory, storage and transportation positions to accomplish the objectives of our producer services, end-use origination and wholesale marketing groups. Except in very limited circumstances when we are able to designate transportation, storage or inventory positions as part of a fair value hedge, SFAS 133 generally does not allow us to mark our inventory, transportation or storage positions to market. The result is that while a significant majority of our natural gas marketing positions are fully economically hedged, we are required to mark some parts of our overall strategies (the derivatives) to market value, but are generally precluded from marking the rest of our economic hedges (transportation, inventory or storage) to market. Volatility in reported earnings and derivative positions should be expected given these accounting requirements.

The sources of fair value measurements for natural gas marketing derivative contracts were as follows (in thousands):

	Maturities
Source of Fair Value	Less than 1 year		1 – 2 years		Total Fair Value

Actively quoted (i.e., exchange-traded) prices	$	2,014	$	830	$	2,844
Prices provided by other external sources		(1,998)		(943)		(2,941)

Total	$	16	$	(113)	$	(97)

The following table presents a reconciliation of our June 30, 2005 natural gas marketing positions recorded at fair value under generally accepted accounting principles (GAAP) to a non-GAAP measure of the fair value of our natural gas forward book wherein all forward trading positions are marked-to-market (in thousands). The approach used in determining the non-GAAP measure is consistent with our previous accounting methods under EITF 98-10. As part of our GAAP fair value calculations we include a “Liquidity Reserve” to reflect a scenario in which there is immediate liquidation of our natural gas contracts on the balance sheet date. We have added back this liquidity reserve in the non-GAAP presentation below as we anticipate holding our natural gas contracts until their settlement and therefore not incur the impact of the bid/ask spread in our realized gross margin.

Fair value of our natural gas marketing positions marked-to-market in accordance with GAAP
(see footnote (a) above)	$	(97)
Increase in fair value of inventory, storage and transportation positions that are
part of our forward trading book, but that are not marked-to-market under GAAP		5,670

“Liquidity Reserve” included in GAAP marked-to-market fair value (b)		2,620

Fair value of all forward positions excluding the “Liquidity Reserve” (Non-GAAP)	$	8,193

(b)

In accordance with generally accepted accounting principles and industry practice, the Company includes a “Liquidity Reserve” in its GAAP marked-to-market fair value. This “Liquidity Reserve” accounts for the estimated impact of the bid/ask spread in a liquidation scenario under which the Company is forced to liquidate its forward book on the balance sheet date.

There have been no material changes in market risk faced by us from those reported in our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission. For more information on market risk, see Part II, Item 7 in our 2004 Annual Report on Form 10-K, and Note 15 of our Notes to Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

ITEM 4.

CONTROLS AND PROCEDURES

Our Chief Executive Officer and Chief Financial Officer evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (Exchange Act)) as of June 30, 2005. Based on their evaluation, they have concluded that our disclosure controls and procedures are adequate and effective to ensure that material information relating to us that is required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the required time periods.

On January 21, 2005, we acquired Cheyenne Light, Fuel and Power (CLF&P). We have not been able to complete an assessment of CLF&P’s internal control over financial reporting between the acquisition date and the end of this reporting period. The Securities and Exchange Commission allows companies one year after acquisition to complete their assessment.

Since the acquisition of CLF&P, we have been focusing on integrating it into our company. We have and will continue to analyze and implement changes in CLF&P’s procedures and controls to ensure their effectiveness.

Other than changes resulting from our acquisition of CLF&P, there have been no changes in our internal control over financial reporting that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

Item 2.

Unregistered Sales of Equity Securities and Use of Proceeds

Unregistered Sales of Equity Securities

On July 7, 2005, we caused the mandatory conversion of all outstanding Series 2000-A Preferred Stock into 195,599 shares of our common stock and $165.78 in cash in lieu of fractional shares pursuant to the automatic conversion feature in Section 8 of our Statement of Designations, Preferences and Relative Rights and Limitations of No Par Preferred Stock, Series 2000-A (the “Statement of Designations”). As a result of this transaction, we have no outstanding shares of Preferred Stock. As set forth in Section 8 of the Statement of Designations, each share of Series 2000-A Preferred Stock was converted into a number of shares of our common stock equal to the liquidation preference amount of $1,000 per share of Series 2000-A Preferred Stock, plus accrued and unpaid dividends thereon, divided by the conversion price of $35.00 per share.

The issuance of 195,599 shares of our common stock upon conversion of all of the outstanding shares of Series 2000-A Preferred Stock was exempt from registration pursuant to Section 3(a)(9) of the Securities Act of 1933. We received no additional proceeds from the issuance of the shares of common stock in exchange for the Series 2000-A Preferred Stock.
