**Safe Harbor for Forward Looking Information**

 

This Annual Report on Form 10-K 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-K 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 Item 1 of this Form 10-K and the following:

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.

We engage in the generation, transmission and distribution of electricity.  We have a solid foundation of revenues, earnings and cash flow that support our capital expenditures, dividends, and overall performance and growth. 

 

***Distribution and Transmission***

 

***Distribution and Transmission.***Our distribution and transmission businesses serve approximately 63,500 electric customers, with an electric transmission system of 447 miles of high voltage lines and 511 miles of lower voltage lines.  In addition, we jointly own 47 miles of high voltage lines with Basin Electric Cooperative.  Our service territory covers a 9,300 square mile area of western South Dakota, northeastern Wyoming and southeastern Montana with a strong and stable economic base.  Approximately 90 percent of our retail electric revenues in 2005 were generated in South Dakota.

The following are characteristics of our distribution and transmission businesses:

 

| **•**    We have a diverse customer and revenue base.  Our revenue mix for the year ended December 31, 2005 was comprised of 26 percent commercial, 21 percent residential, 12 percent contract wholesale, 25 percent wholesale off-system, 11 percent industrial and 5 percent municipal sales and other revenue.  Approximately 81 percent of our large commercial and industrial customers are provided service under long-term contracts.  We have historically optimized the utilization of our power supply resources by selling wholesale power to other utilities and to power marketers in the spot market and through short-term sales contracts.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 |

| **•**    We are subject to regulation by the South Dakota Public Utilities Commission (SDPUC) and the Wyoming Public Service Commission (WPSC).  The retail rate freeze granted to us by the SDPUC, which had been in effect for 10 years, expired on January 1, 2005.  Our current rates in South Dakota and Wyoming remain in place following the expiration of the rate freeze.  The rate freeze preserved our low-cost rate structure for our retail customers at levels below the national average while allowing us to retain the benefits from cost savings and from wholesale “off-system” sales, which were not covered by the rate freeze.  Our rates do not include a fuel or a purchased power adjustment, so we continue to have the flexibility in allocating our generatingcapacity to wholesale off-system sales.  While we are not obligated to do so, we are permitted to petition the SDPUC and WPSC for a rate increase at any time, or the SDPUC and WPSC may require that we do so.  We will continue to monitor our rate structure and when appropriate, file a rate case.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      |

| **•**    Black Hills Power and Basin Electric Power Cooperative completed the construction of an AC-DC-AC transmission tie in the fourth quarter of 2003.  We own 35 percent and Basin Electric owns 65 percent of the transmission tie.  The transmission tie provides an interconnection between the Western and Eastern transmission grids, enabling access to both the WECC region in the West, and the Mid-Continent Area Power Pool, or “MAPP” region in the East.  Our system is located in the WECC region.  The total transfer capacity of the tie is 400 megawatts - 200 megawatts from West to East and 200 megawatts from East to West.  This transmission tie allows us to buy and sell energy in the Eastern interconnection without having to isolate and physicallyreconnect load or generation between the two electrical transmission grids.  The transmission tie is bidirectional and thus accommodates scheduling transactions in both directions simultaneously.  This transfer capability provides additional opportunity to sell our excess generation or to make economic purchases to serve our native load and our contract obligations, and to take advantage of the power price differentials between the two electric grids.  Additionally, our system is capable of directly interconnecting up to 80 megawatts of generation or load to the Eastern transmission grid.  Transmission constraints within the MAPP transmission system may limit the amount of capacity that may be directly interconnected to the Eastern system at any given time.**** |

***Power Sales Agreements.***  We sell a portion of our current load under long-term contracts.  Our key contracts include:

 

| **•**      an agreement with MDU, expiring at the end of 2006, for the sale of up to 55 megawatts of capacity and energy to serve the Sheridan, Wyoming electric service territory.  We entered into a new power purchase agreement with MDU for the supply of up to 74 megawatts of capacity and energy for Sheridan, Wyoming from 2007 through 2016, which is subject to regulatory approval by the WPSC; and |
|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|                                                                                                                                                                                                                                                                                                                                                                                                                                               |
| **•**      an agreement with the City of Gillette, Wyoming, expiring in 2013, to provide the city’s first 23 megawatts of capacity and energy.  The agreement renews automatically and requires a seven year notice of termination.                                                                                                                                                                        |

 

These consumers are integrated into our control area and are treated as firm native load.  We also provide 20 megawatts of unit contingent energy and capacity to MEAN under a contract that expires in 2013.

 

***Regulated Power Plants and Purchased Power.***  Our electric load is primarily served by our generating facilities in South Dakota and Wyoming, which provide 435 megawatts of generating capacity, with the balance supplied under purchased power and capacity contracts.  Approximately 50 percent of our capacity is coal-fired, 39 percent is oil- or gas-fired, and 11 percent is supplied under the following purchased power contracts with PacifiCorp:

 

| **•**      a power purchase agreement expiring in 2023, involving the purchase by us of 50 megawatts of baseload power; and                                                                        |
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|                                                                                                                                                                                                                                  |
| **•**      a reserve capacity integration agreement expiring in 2012, which makes available to us 100 megawatts of reserve capacity in connection with the utilization of the Ben French CT units. |

 

Since 1995, we have been a net producer of energy.  We reached our peak system load of 401 megawatts in July 2005.  None of our generation is restricted by hours of operation, thereby providing us the ability to generate power to meet demand whenever necessary and economically feasible.

**Rate Regulation**

 

***Rate Regulation***

 

The rate freeze granted by the SDPUC, which had been in effect for us since 1995, expired on January 1, 2005.  During this ten-year term, we were prohibited, subject to certain limited exceptions, from filing for any increase in our rates or invoking any fuel and purchased power adjustment tariff which would take effect during the freeze period.  While the rate freeze has expired, we cannot raise rates without initiating a proceeding before the SDPUC and the WPSC and receiving approval from these commissions.  As such, our rates in place during the freeze period remain in effect.

 

Unless and until we file for and receive a rate increase, we are undertaking the risks of:

 

| **•**     machinery failure;                                                                                                             |
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| **•**     load loss caused by either an economic downturn or changes in regulation;                                                      |
| **•**     increased costs of fuel commodities;                                                                                           |
| **•**     increased costs under power purchase contracts over which it has no control;                                                   |
| **•**     government impositions; and                                                                                                    |
| **•**     acts of nature and other unexpected events that could cause material losses of income or increases in costs of doing business. |

 

***Regulatory Accounting***

 

As it pertains to the accounting for our utility operations, we follow SFAS No. 71, “Accounting for the Effects of Certain Types of Regulation,” and our financial statements reflect the effects of the different ratemaking principles followed by the various jurisdictions in which we operate.  If rate recovery becomes unlikely or uncertain, due to competition or regulatory action, these accounting standards may no longer apply to our generation operations.  In the event we determine that we no longer meet the criteria for following SFAS 71, the accounting impact to us could be an extraordinary non-cash charge to operations of an amount that could be material.  Criteria that may give rise to the discontinuance of SFAS 71 include increasing competition that could restrict our ability to establish prices to recover specific costs and a significant change in the manner in which rates are set by regulatorsfrom cost-based regulation to another form of regulation.  We periodically review these criteria to ensure that the continuing application of SFAS 71 is appropriate.

| **ITEM 1A.** | **RISK FACTORS** |
|--------------|------------------|

 

The following specific risk factors and other risk factors that we discuss in our periodic reports from time to time should be considered for a better understanding of our Company.  These factors and other matters discussed herein are important factors that could cause our actual results or outcomes to differ materially from those discussed in the forward looking statements included elsewhere in this document.

 

**Our credit ratings could be lowered in the future.  If this were to occur, our access to capital and our cost of capital and other costs would be negatively affected.**

 

Our issuer credit rating is “Baa2” by Moody’s Investor Services, Inc., or Moody’s and “BBB-” by Standard & Poors.  Our credit rating on our First Mortgage Bonds is “Baa1” by Moody’s and “BBB” by Standard & Poor’s.  Any reduction in our ratings by Moody’s or Standard & Poor’s Rating Service could adversely affect our ability to refinance or repay our existing debt and to complete new financings.  In addition, a downgrade in our credit rating would increase our costs of borrowing under some of our existing debt obligations.  A downgrade could also result in our business counterparties requiring us to provide additional amounts of collateral under new transactions.

 

**We may not raise our retail rates without prior approval of the South Dakota Public Utilities Commission or the Wyoming Public Services Commission.  If we seek rate relief, we could experience delays in obtaining approvals and could have rate recovery disallowed in rate proceedings.**

 

Our rate freeze agreement with the SDPUC expired on January 1, 2005.  Until such time as we petition the SDPUC or the WPSC for rate relief, or either commission requires that we do so, we may not increase our retail rates.  Additionally, we 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 we are generally unable to increase our 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 we 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, we may be required to purchasereplacement power in wholesale power markets at prices that exceed the rates we are permitted to charge our retail customers.  Finally, our costs would be subject to the review of the SDPUC or the WPSC, and the commissions could find certain costs not to be recoverable, thus negatively affecting our revenues.

 

**Because prices in the wholesale power markets are volatile, our revenues and expenses may fluctuate.**

 

A portion of the variability of our net income in recent years has been attributable to wholesale electricity sales.  The related power prices are influenced by many factors outside our control, including:

 

| **•**      fuel prices;                                                                 |
|----------------------------------------------------------------------------------------------------------------------------|
| **•**      transmission constraints;                                                    |
| **•**      supply and demand;                                                           |
| **•**      weather;                                                                     |
| **•**      economic conditions; and                                                     |
| **•**      the rules, regulations and actions of the system operators in those markets. |

Moreover, unlike most other commodities, electricity cannot be stored and therefore must be produced concurrently with its use.  As a result, wholesale power markets are subject to significant price fluctuations over relatively short periods of time and can be unpredictable.

 

**Construction, expansion, refurbishment and operation of power generating and transmission and resource recovery facilities involve significant risks which could lead to lost revenues or increased expenses.**

 

The construction, expansion, refurbishment and operation of power generating and transmission facilities involve many risks, including:

 

| **•**     the inability to obtain required governmental permits and approvals; |
|--------------------------------------------------------------------------------------------------------------|
| **•**     the unavailability of equipment;                                     |

The ongoing operation of our facilities involves all of the risks described above, in addition to risks relating to the breakdown or failure of equipment or processes and performance below expected levels of output or efficiency.  New plants may employ recently developed and technologically complex equipment, especially in the case of newer environmental emission control technology.  Any of these risks could cause us to operate below expected capacity levels, which in turn could result in lost revenues, increased expenses, higher maintenance costs and penalties.  While we maintain insurance, obtain warranties from vendors and obligate contractors to meet certain performance levels, the proceeds of such insurance and our rights under warranties or performance guarantees may not be adequate to cover lost revenues, increased expenses or liquidated damage payments.

 

**Our business is subject to substantial governmental regulation and permitting requirements as well as on-site environmental liabilities we assumed when we acquired some of our facilities.  We may be adversely affected by any future inability to comply with existing or future regulations or requirements or the potentially high cost of complying with such requirements.**

 

Our business is subject to extensive energy, environmental and other laws and regulations of federal, state and local authorities.  We generally are required to obtain and comply with a wide variety of licenses, permits and other approvals in order to operate our facilities.  In the course of complying with these requirements, we may incur significant additional costs.  If we fail to comply with these requirements, we could be subject to civil or criminal liability and the imposition of liens or fines.  In addition, existing regulations may be revised or reinterpreted, new laws and regulations may be adopted or become applicable to us or our facilities, and future changes in laws and regulation may have a detrimental effect on our business.

We strive at all times to be in compliance with all applicable environmental laws and regulations.  However, steps to bring our facilities into compliance, if necessary, could be expensive, and thus could adversely affect our results of operation and financial condition.  Furthermore, with the continuing trends toward stricter standards, greater regulation, more extensive permitting requirements and an increase in the assets we operate, we expect our environmental expenditures to be substantial in the future.

 

**Ongoing changes in the United States utility industry, such as state and federal regulatory changes, a potential increase in the number of our competitors or the imposition of price limitations to address market volatility, could adversely affect our profitability.**

 

The United States electric utility industry is currently experiencing increasing competitive pressures as a result of:

 

| **•**      the Energy Policy Act of 2005 and the repeal of the Public Utility Holding Company Act of 1935; |
|-----------------------------------------------------------------------------------------------------------------------------------------------|
| **•**      consumer demands;                                                                               |
| **•**      technological advances; and                                                                     |
| **•**      greater availability of natural gas-fired power generation, and other factors.                  |

 

FERC has implemented and continues to propose regulatory changes to increase access to the nationwide transmission grid by utility and non-utility purchasers and sellers of electricity.  In addition, a number of states have implemented or are considering or currently implementing methods to introduce and promote retail competition.  Industry deregulation in some states has led to the disaggregation of some vertically integrated utilities into separate generation, transmission and distribution businesses, and deregulation initiatives in a number of states may encourage further disaggregation.  As a result, significant additional competitors could become active in the generation, transmission and distribution segments of our industry, which could negatively affect our ability to expand our asset base.

 

In addition, the independent system operators who oversee many of the wholesale power markets have in the past imposed, and may in the future continue to impose, price limitations and other mechanisms to address some of the volatility in these markets.  These types of price limitations and other mechanisms may adversely affect the profitability of those generating facilities that sell energy into the wholesale power markets.  Given the extreme volatility and lack of meaningful long-term price history in some of these markets and the imposition of price limitations by independent system operators, we may not be able to operate profitably in all wholesale power markets.

In 2003, we made a non-cash dividend to our parent company, Black Hills Corporation, consisting of our 100 percent ownership in Black Hills Generation, Inc., formerly known as Black Hills Energy Capital, Inc.  As a result, we no longer have any subsidiaries and operate only in the electric utility business.

2005 Compared to 2004

 

Electric revenue increased 9 percent for the year ended December 31, 2005 compared to the same period in the prior year.  Firm commercial, residential and contract wholesale sales increased 5 percent, 8 percent and 3 percent, respectively.  Cooling degree days for the year were 59 percent higher than 2004 and heating degree days were 1 percent lower than 2004.  Wholesale off-system sales increased 25 percent due to a 33 percent increase in average price received partially offset by a 6 percent decrease in megawatt-hours sold.  

 

Electric operating expenses increased 18 percent for the year ended December 31, 2005, compared to the prior year.  Higher operating expenses were primarily the result of an $18.5 million increase in fuel and purchased power costs.  The increase in fuel and purchased power was due to a $16.9 million increase in purchased power, which includes $2.8 million of additional purchase power costs to cover the outage of Neil Simpson II, as well as a 31 percent increase in average price per megawatt-hour, and a 3 percent increase in megawatt-hours purchased.  Fuel costs increased $1.6 million due to a 12 percent increase in average cost, partially offset by a 1 percent decrease in megawatt-hours generated.  Megawatt-hours produced through coal-fired generation decreased while higher cost gas generation was utilized in 2005.  Purchased power and gas generation were utilized for firm load demand and peaking needs due tounscheduled plant outages and warmer weather.  The increase in operating expense was also affected by increased power marketing legal expense, compensation costs and corporate allocations, partially offset by lower maintenance costs due to scheduled and unscheduled plant maintenance in 2004.

 

Income from continuing operations decreased $1.2 million primarily due to increased fuel and purchased power costs, legal expense, compensation costs and corporate allocations, partially offset by increased revenues, lower maintenance costs, lower interest expense due to the pay down of debt, and a $1.9 million benefit from a deferred tax adjustment.

 

2004 Compared to 2003

 

Electric revenue increased 2 percent in 2004 compared to 2003, primarily due to a 13 percent increase in wholesale off-system sales offset by decreased transmission revenues due to lower approved rates and higher load share of our Open Access Transmission Tariff revenues.

 

Residential and commercial sales decreases of 3 percent and 2 percent, respectively, in 2004 accounted for a $1.7 million decrease in revenue.  These decreases were partially offset by a 1 percent increase in industrial sales.  The 15 percent increase in wholesale off-system megawatt-hours accounted for a $4.5 million increase in revenues.  Cooling degree days were 41 percent lower than 2003 and heating degree days were 7 percent lower than 2003.

 

Electric utility operating expenses increased $10.0 million due to a $5.9 million increase in fuel and purchased power cost, a $4.5 million increase in certain operations and maintenance costs, including scheduled and unscheduled maintenance costs, increased group insurance and corporate allocations and increased costs associated with the increase in wholesale off-system sales, partially offset by decreased interest expense of $0.9 million, primarily due to retirement of debt.

 

The increase in fuel and purchased power cost was due to an $11.8 million increase in purchased power costs, offset by a $5.9 million decrease in fuel costs, as prevailing gas prices made it more economical for us to purchase power for our peaking needs and increased off-system sales, rather than generate energy utilizing our gas turbines.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 

To the Stockholder of

Black Hills Power, Inc.

Rapid City, South Dakota

 

We have audited the accompanying balance sheets of Black Hills Power, Inc. (the Company) as of December 31, 2005 and 2004, and the related statements of income, common stockholder’s equity and comprehensive income, and cash flows for each of the three years in the period ended December 31, 2005.  These financial statements are the responsibility of the Company’s management.  Our responsibility is to express an opinion on these financial statements based on our audits.

 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.  The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting.****Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting.  Accordingly, we express no such opinion.  An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financialstatements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

 

In our opinion, such financial statements present fairly, in all material respects, the financial position of Black Hills Power, Inc. as of December 31, 2005 and 2004, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2005, in conformity with accounting principles generally accepted in the United States of America.

 

As discussed in Note 1, the accompanying 2003 Statement of Cash Flows has been restated.

**NOTES TO FINANCIAL STATEMENTS**

**December 31, 2005, 2004 and 2003**

 

| **(1)** | **BUSINESS DESCRIPTION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES** |
|---------|-------------------------------------------------------------------------|

 

**Business Description**

 

Black Hills Power, Inc. (the Company) is an electric utility serving customers in South Dakota, Wyoming and Montana.  The Company is a wholly owned subsidiary of the publicly traded Black Hills Corporation (the Parent).

 

**Basis of Presentation**

 

The financial statements include the accounts of Black Hills Power, Inc. and also the Company’s ownership interests in the assets, liabilities and expenses of its jointly-owned facilities (see Note 3.).  As discussed in Note 11, the Company has distributed the stock held in its subsidiaries in the form of non-cash dividends to the Parent.  These distributions represented 100 percent ownership of the subsidiaries.  Activity at the subsidiaries was recorded up to the date of distribution and has been reclassified into “Discontinued operations” in the accompanying statements of income. 

 

**Use of Estimates**

 

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  The most significant estimates relate to allowance for uncollectible accounts receivable, long-lived asset values and useful lives, employee benefits plans and contingencies.  Actual results could differ from those estimates.

 

**Regulatory Accounting**

 

The Company’s regulated electric operations are subject to regulation by various state and federal agencies.  The accounting policies followed are generally subject to the Uniform System of Accounts of the Federal Energy Regulatory Commission (FERC).

 

The Company’s electric operations follow the provisions of the Financial Accounting Standards Board (FASB) of Statement of Financial Accounting Standards (SFAS) No. 71, “Accounting for the Effects of Certain Types of Regulation” (SFAS 71), and its financial statements reflect the effects of the different ratemaking principles followed by the various jurisdictions regulating its electric operations.  If rate recovery becomes unlikely or uncertain, due to competition or regulatory action, these accounting standards may no longer apply to the Company’s regulated generation operations.  In the event the Company determines that it no longer meets the criteria for following SFAS 71, the accounting impact to the Company would be an extraordinary non-cash charge to operations of an amount that could be material.  Criteria that give rise to the discontinuance of SFAS 71 include increasingcompetition that could restrict the Company’s ability to establish prices to recover specific costs and a significant change in the manner in which rates are set by regulators from cost-based regulation to another form of regulation.  The Company periodically reviews these criteria to ensure the continuing application of SFAS 71 is appropriate.

 

20

 

 

 

At December 31, 2005 and 2004, the Company had regulatory assets of $6.9 million and $7.2 million and regulatory liabilities of $5.7 million and $6.0 million, respectively.  Regulatory assets are primarily recorded for the probable future revenue to recover future income taxes related to the deferred tax liability for the equity component of allowance for funds used during construction of utility assets and for unamortized losses on reacquired debt.  Regulatory liabilities include the probable future decrease in rate revenues related to a decrease in deferred tax liabilities for prior reductions in statutory federal income tax rates and also the cost of removal for utility plant, recovered through the Company’s electric utility rates.

 

**Cash Equivalents**

 

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.

 

**Reclassifications**

 

 

**Cash Flow Statement Restatement**

 

Subsequent to the issuance of its financial statements for the year ended December 31, 2003, the Company determined that the cash flows associated with discontinued operations should have been presented within the Statements of Cash Flows.  As a result, during 2005, the Company changed the presentation of cash flows from discontinued operations to present separate disclosure of the cash flows from operating, investing and financing activities.  In addition, beginning of year cash and cash equivalents in the 2003 Statement of Cash Flows was adjusted to include cash and cash equivalents from discontinued operations.  A summary of the effects of these changes on the Statement of Cash Flows for the year ended December 31, 2003, is as follows (in thousands):

|                                                                |   | 2003         |
|---------------------------------------------------------------------|--------|--------------|
|                                                                |   |         |

**Materials, Supplies and Fuel**

 

Materials, supplies and fuel used for construction, operation and maintenance purposes are generally stated at cost on a weighted-average basis.  To the extent fuel has been designated as the underlying hedged item in a “fair value” hedge transaction, those volumes are stated at market value using published industry quotations.  As of December 31, 2005, market adjustments related to fuel were $(0.2) million.

 

**Deferred Financing Costs**

 

Deferred financing costs are amortized using the effective interest method over the term of the related debt.

 

**Property, Plant and Equipment**

 

Additions to property, plant and equipment are recorded at cost when placed in service.  Included in the cost of regulated construction projects is an allowance for funds used during construction (AFUDC) which represents the approximate composite cost of borrowed funds and a return on capital used to finance the project.  The amount of AFUDC was approximately $0.2 million, $0.2 million, and $0.1 million in 2005, 2004 and 2003, respectively.  The cost of regulated electric property, plant and equipment retired, or otherwise disposed of in the ordinary course of business, less salvage, is charged to accumulated depreciation.  Repairs and maintenance of property are charged to operations as incurred.

 

Depreciation provisions for regulated electric property, plant and equipment is computed on a straight-line basis using an annual composite rate of 3.1 percent in 2005, 3.0 percent in 2004 and 3.1 percent in 2003.

 

**Derivatives and Hedging Activities**

 

The Company, from time to time, utilizes risk management contracts including forward purchases and sales and fixed-for-float swaps to hedge the price of fuel for its combustion turbines, maximize the value of its natural gas storage or to fix the interest on its variable rate debt.  Certain of the contracts qualify as derivatives under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities” (SFAS 133).  SFAS 133 requires that every derivative instrument be recorded in the balance sheet as either an asset or liability measured at its fair value.  SFAS 133 requires that changes in the derivative instrument’s fair value be recognized currently in earnings unless specific hedge accounting criteria are met.

 

SFAS 133 allows hedge accounting for qualifying fair value and cash flow hedges.  SFAS 133 provides that the gain or loss on a derivative instrument designated and qualifying as a fair value hedging instrument as well as the offsetting loss or gain on the hedged item attributable to the hedged risk be recognized currently in earnings in the same accounting period.  SFAS 133 provides that the effective portion of the gain or loss on a derivative instrument designated and qualifying as a cash flow hedging instrument be reported as a component of other comprehensive income and be reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings.  The remaining gain or loss on the derivative instrument, if any, is recognized currently in earnings.

 

 

22

 

 

 

**Impairment of Long-Lived Assets**

 

The Company periodically evaluates whether events and circumstances have occurred which may affect the estimated useful life or the recoverability of the remaining balance of its long-lived assets.  If such events or circumstances were to indicate that the carrying amount of these assets was not recoverable, the Company would estimate the future cash flows expected to result from the use of the assets and their eventual disposition.  If the sum of the expected future cash flows (undiscounted and without interest charges) was less than the carrying amount of the long-lived assets, the Company would recognize an impairment loss.  No impairment loss was recorded during 2005, 2004 or 2003.

 

**Income Taxes**

 

The Company uses the liability method in accounting for income taxes.  Under the liability method, deferred income taxes are recognized, at currently enacted income tax rates, to reflect the tax effect of temporary differences between the financial and tax basis of assets and liabilities.  Such temporary differences are the result of provisions in the income tax law that either require or permit certain items to be reported on the income tax return in a different period than they are reported in the financial statements.  The Company classifies deferred tax assets and liabilities into current and non-current amounts based on the classification of the related assets and liabilities.

 

The Company files a federal income tax return with other affiliates.  For financial statement purposes, federal income taxes are allocated to the individual companies based on amounts calculated on a separate return basis. 

 

**Revenue Recognition**

 

Revenue is recognized when there is persuasive evidence of an arrangement with a fixed or determinable price, delivery has occurred or services have been rendered, and collectibility is reasonably assured.

**__________________________**

| (a) | In the fourth quarter of 2004, the Company called and refinanced $18.7 million of pollution control revenue bonds.                      |
|-----|-----------------------------------------------------------------------------------------------------------------------------------------|
| (b) | At December 31, 2004, the Company had $3.1 million of cash restricted to maintain liquidity for our $2.9 million Series 94A bond issue. |

 

Substantially all of the Company’s property is subject to the lien of the indenture securing its first mortgage bonds.  First mortgage bonds of the Company may be issued in amounts limited by property, earnings and other provisions of the mortgage indentures.

| **(5)** | **FAIR VALUE OF FINANCIAL INSTRUMENTS** |

The estimated fair values of the Company’s financial instruments at December 31 are as follows (in thousands):

 

|                      | 2005            | 2004       |
|---------------------------|-----------------|------------|

The following methods and assumptions were used to estimate the fair value of each class of the Company’s financial instruments.

 

**Cash and Cash Equivalents and Restricted Cash**

The carrying amount approximates fair value due to the short maturity of these instruments.

 

**Long-Term Debt**

 

The fair value of the Company’s long-term debt is estimated based on quoted market rates for debt instruments having similar maturities and similar debt ratings.  The Company’s outstanding first mortgage bonds are either currently not callable or are subject to make-whole provisions which would eliminate any economic benefits for the Company to call and refinance the first mortgage bonds.

**__________________________**

| * | The expected rate of return on plan assets was changed from 9.00 percent in 2005 to 8.50 percent for the calculation of the 2006 net periodic pension cost.  This change is expected to increase pension costs in 2006 by approximately $0.3 million. |
|---|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

 

The Plan’s expected long-term rate of return on assets assumption is based upon the weighted average expected long-term rate of returns for each individual asset class.  The asset class weighting is determined using the target allocation for each asset class in the Plan portfolio.  The expected long-term rate of return for each asset class is determined primarily from long-term historical returns for the asset class, with adjustments if it is anticipated that long-term future returns will not achieve historical results.

 

The expected long-term rate of return for equity investments was 9.5 percent and 10.0 percent for the 2005 and 2004 plan years, respectively.  For determining the expected long-term rate of return for equity assets, the Company reviewed annual 20-, 30-, 40-, and 50-year returns on the S&P 500 Index, which were, at December 31, 2005, 11.8 percent, 12.5 percent, 10.1 percent and 10.3 percent respectively.  Fund management fees were estimated to be 0.18 percent for S&P 500 Index assets and 0.45 percent for other assets.  The expected long-term rate of return on fixed income investments was 6.0 percent; the return was based upon historical returns on 10-year treasury bonds of 7.0 percent from 1962 to 2005, and adjusted for recent declines in interest rates. The expected long-term rate of return on cash investments was estimated to be 4.0 percent; expected cash returns were estimated to be 2.0 percent belowlong-term returns on intermediate-term treasury bonds.

| Total           | 100.0% | 100.0% |

 

The Plan’s investment policy includes a target asset allocation as follows:

 

| Asset Class    | Target Allocation*                                                     |

| US Stocks      | 60% (with a variance of no more or less than 10% of target).           |
| Foreign Stocks | 30% (with a variance of no more or less than 10% of target).           |
| Fixed Income   | 5% (with a variance of no more than 10% or no less than 5% of target). |
| Cash           | 5% (with a variance of no more than 10% or no less than 5% of target). |

___________________________

| * | The Plan’s investment policy has been modified for 2006 to target an allocation of 50 percent U.S. stock, 25 percent foreign stock and 25 percent fixed income. |
|---|----------------------------------------------------------------------------------------------------------------------------------------------------------------------|

 

The Plan’s investment policy includes the investment objective that the achieved long-term rates of return meet or exceed the assumed actuarial rate.  The policy strategy seeks to prudently invest in a diversified portfolio of predominately equity-based assets.  The policy provides that the Plan will maintain a passive core US Stock portfolio based on the S&P 500 Index.  Complementing this core will be investments in US and foreign equities through actively managed mutual funds.  

 

The policy contains certain prohibitions on transactions in separately managed portfolios in which the Plan may invest, including prohibitions on short sales and the use of options or futures contracts.  With regards to pooled funds, the policy requires the evaluation of the appropriateness of such funds for managing Plan assets if a fund engages in such transactions. The Plan has historically not invested in funds engaging in such transactions.

 

Cash Flows

 

The Company does not anticipate any employer contributions to the Plan in 2006.

It has been determined that the Plan’s post-65 retiree prescription drug plans are actuarially equivalent and qualify for the Medicare Part D subsidy.

 

The effect on the accumulated postretirement benefit obligation for the fiscal year ending December 31, 2005, was an actuarial gain of approximately $1.1 million.  The effect on 2006 net periodic postretirement benefit cost will be a decrease of approximately $0.1 million.

The healthcare trend rate assumption for the 2005 fiscal year benefit obligation determination and 2006 fiscal year expense is 11 percent for 2005 grading down 1 percent per year until a 5 percent ultimate trend rate is reached in fiscal year 2011.  The healthcare cost trend rate assumption for the 2004 fiscal year benefit obligation determination and 2005 fiscal year expense was 12 percent for 2004 grading down 1 percent per year until a 5 percent ultimate trend rate is reached in fiscal year 2011.

 

A 1 percent increase in the healthcare cost trend assumption would increase the service and interest cost $0.2 million or 23 percent and the accumulated periodic postretirement benefit obligation $1.3 million or 18 percent.  A 1 percent decrease would reduce the service and interest cost by $0.1 million or 18 percent and the accumulated periodic postretirement benefit obligation $1.0 million or 15 percent.

**RELATED-PARTY TRANSACTIONS**

 

Receivables and Payables

 

The Company has accounts receivable balances related to transactions with other Black Hills Corporation subsidiaries.  The balances were $2.0 million and $0.9 million as of December 31, 2005 and 2004, respectively.  The Company also has accounts payable balances related to transactions with other Black Hills Corporation subsidiaries.  The balances were $1.6 million and $0.3 million as of December 31, 2005 and 2004, respectively.

 

Notes Payable - Affiliate

 

The Company has borrowings from its Parent, which are due on demand.  Outstanding advances were $1.8 million at December 31, 2005 and $25.1 million at December 31, 2004.  Advances under this note bear interest at 0.70 percent above the daily LIBOR rate (5.09 percent at December 31, 2005).  Interest paid was $0.8 million and $0.1 million for the years ended December 31, 2005 and 2004, respectively.

 

In August 2005, the Company entered into a Utility Money Pool Agreement with the Parent; and Cheyenne Light, Fuel & Power, an electric and gas utility subsidiary of the Parent.

 

 

38

 

 

 

Under the agreement, the Company may borrow from the Parent.  The Agreement restricts the Company from loaning funds to the Parent or to any of the Parent’s non-utility subsidiaries; the Agreement does not restrict the Company from making dividends to the Parent.  Borrowings under the Agreement bear interest at the daily cost of external funds as defined under the Agreement, or if there are no external funds outstanding on that date, then the rate will be the daily one-month LIBOR rate plus 100 basis points.  

 

Other Balances and Transactions

 

The Company purchases coal from Wyodak Resources Development Corp., an indirect subsidiary of the Parent.  The amount purchased during the years ended December 31, 2005, 2004 and 2003 was $10.1 million, $9.6 million and $10.3 million, respectively.

 

In addition to the above transactions, in order to fuel its combustion turbine, the Company purchased natural gas from Enserco Energy, an indirect subsidiary of the Parent.  The amount purchased during the years ended December 31, 2005, 2004 and 2003 was approximately $6.4 million, $2.7 million and $6.1 million, respectively.  These amounts are included in “Fuel and purchased power” on the Statements of Income.

 

The Company also received revenues of approximately $2.2 million for the year ended December 31, 2005 and $1.1 million for the years ended December 31, 2004 and 2003, respectively, from Black Hills Wyoming, Inc., an indirect subsidiary of Black Hills Corporation, for the transmission of electricity.

**COMMITMENTS AND CONTINGENCIES**

 

**Power Purchase and Transmission Services Agreements – Pacific Power**

 

In 1983, the Company entered into a 40 year power purchase agreement with PacifiCorp providing for the purchase by the Company of 75 megawatts of electric capacity and energy from PacifiCorp’s system.  An amended agreement signed in October 1997 reduces the contract capacity by 25 megawatts (5 megawatts per year starting in 2000).  The price paid for the capacity and energy is based on the operating costs of one of PacifiCorp’s coal-fired electric generating plants.  Costs incurred under this agreement were $10.1 million in 2005, $10.0 million in 2004 and $10.8 million in 2003.

 

In addition, the Company has a firm network transmission agreement for 36 megawatts of capacity with PacifiCorp that expires on December 31, 2006.  Annual costs are approximately $0.9 million per year.  The Company uses this agreement to serve the Sheridan, Wyoming electric service territory under our contract with Montana-Dakota Utilities Company.

 

The Company also has a firm point-to-point transmission service agreement with PacifiCorp that expires on December 31, 2023.  The agreement provides that the following amounts of capacity and energy be transmitted:  32 megawatts in 2001, 27 megawatts in 2002, 22 megawatts in 2003, 17 megawatts in 2004-2006 and 50 megawatts in 2007-2023.  Costs incurred under this agreement were $0.4 million in 2005, $0.4 million in 2004 and $0.5 million in 2003.

 

 

39

 

 

 

**Long-Term Power Sales Agreements**

 

**•**

The Company has a ten-year power sales contract with the Municipal Energy Agency of Nebraska (MEAN) for 20 megawatts of contingent capacity from the Neil Simpson Unit #2 plant.  The contract expires in February 2013.

 

 

**•**

The Company has a contract with Montana-Dakota Utilities Company, expiring January 1, 2007, for the sale of up to 55 megawatts of energy and capacity to service the Sheridan, Wyoming electric service territory.  The Company entered into a new power purchase agreement with MDU for the supply of up to 74 megawatts of capacity and energy for Sheridan, Wyoming from 2007 through 2016, which is subject to regulatory approval by the WPSC.  The Company also has a contract with the City of Gillette, Wyoming, expiring in 2012, to provide the city’s first 23 megawatts of capacity and energy.  The agreement renews automatically and requires a seven-year notice of termination.  Both contracts are served by the Company and are integrated into its control area and are treated as part of the Company’s firm nativeload.

 

**Legal Proceedings**

 

**Forest Fire Claims**

 

In September 2001, a fire occurred in the southwestern Black Hills, now known as the “Hell Canyon Fire.”  It is alleged that the fire occurred when a high voltage electrical span maintained by the Company broke, and electrical arcing from the severed line ignited dry grass.  The fire burned approximately 10,000 acres of land owned by the Black Hills National Forest, the Oglala Sioux Tribe, and other private landowners.  The State of South Dakota initiated litigation against the Company, in the Seventh Judicial Circuit Court, Fall River County, South Dakota, on or about January 31, 2003.  The Complaint seeks recovery of damages for alleged fire suppression and rehabilitation costs.  A claim for treble damages is asserted with respect to the claim for injury to timber.  A substantially similar suit was filed against the Company by the United States Forest Service, on June 30, 2003, in the United StatesDistrict Court for the District of South Dakota, Western Division.  The State subsequently joined its claim in the federal action.  The State claims damages in the amount of approximately $0.8 million for fire suppression and rehabilitation costs.  The United States Government’s claim for fire suppression and related costs has been submitted at approximately $1.3 million.  A trial date has been set for late 2006.  The Company has denied all claims and will vigorously defend this matter, the timing or outcome of which is uncertain.

 

On June 29, 2002, a forest fire began near Deadwood, South Dakota, now known as the “Grizzly Gulch Fire.”  Before being contained more than eight days later, the fire consumed over 10,000 acres of public and private land, mostly consisting of rugged forested areas. The fire destroyed approximately 7 homes and 15 outbuildings. There were no reported personal injuries. In addition, the fire burned to the edge of the City of Deadwood, forcing the evacuation of the City of Deadwood, and the adjacent City of Lead, South Dakota. These communities are active in the tourist and gaming industries. Individuals were ordered to leave their homes, and businesses were closed for a short period of time. On July 16, 2002, the State of South Dakota announced the results of its investigation of the cause and origin of the fire. The State asserted that the fire was caused by tree encroachment into and contact with atransmission line owned and maintained by the Company.

 

 

40

 

 

 

On September 6, 2002, the State of South Dakota commenced litigation against the Company, in the Seventh Judicial Circuit Court, Pennington County, South Dakota. The Complaint seeks recovery of damages for alleged injury to timber, fire suppression and rehabilitation costs.  A claim for treble damages was asserted with respect to the claim for injury to timber.  

 

On March 3, 2003, the United States of America filed a similar suit against the Company, in the United States District Court, District of South Dakota, Western Division.  The federal government’s Complaint likewise seeks recovery of damages for alleged injury to timber, fire suppression and rehabilitation costs.  A similar claim for treble damages is asserted with respect to the claim for injury to timber.  In April 2003, the State of South Dakota intervened in the federal action.  Accordingly, the state court litigation has been stayed, and all governmental claims will be tried in U.S. District Court.  

 

The state and federal government claim approximately $5.3 million for suppression costs, $1.2 million for rehabilitation costs, and $0.6 million for timber loss.  Additional claims could be asserted for alleged loss of habitat and aesthetics or for assistance to private landowners.

 

The Company completed its own investigation of the fire cause and origin and based upon information currently available, the Company filed its Answer to the Complaints of both the State and the United States government, denying all claims, and asserting that the fire was caused by an independent intervening cause, or an act of God.  A trial date has been set for August 2006.  The Company expects to vigorously defend all claims brought by governmental or private parties.  

 

During the period of April 2003 through June 2005, various private civil actions were filed against the Company, asserting that the Grizzly Gulch Fire caused damage to the parties’ real property.  These actions were filed in the Fourth Judicial Circuit Court, Lawrence County, South Dakota.  The Complaints seek recovery on the same theories asserted in the governmental Complaints, but most of the Complaints specify no amount for damage claims.  The Company will vigorously defend these matters as well.

 

Additional claims could be made for individual and business losses relating to injury to personal and real property, and lost income, all arising from the Grizzly Gulch Fire.  A trial date has been set for August 2006.

 

Although we cannot predict the outcome or the viability of potential claims with respect to either fire, based on the information available, management believes that any such claims, if determined adversely to the Company, will not have a material adverse effect on the Company’s financial condition or results of operations. 

 

**PPM Energy, Inc. Demand for Arbitration**

 

On January 2, 2004, PPM Energy, Inc. delivered a Demand for Arbitration to the Company.  The demand alleges claims for breach of contract and requests a declaration of the parties’ rights and responsibilities under an Exchange Agreement executed on or about April 3, 2001. Specifically, PPM Energy asserts that the Exchange Agreement obligates the Company to accept receipt and cause corresponding delivery of electric energy, and to grant access to transmission rights allegedly covered by the Agreement. PPM Energy requests an award of damages in an amount not less than $20.0 million.  The Company filed its Response to Demand, including a counterclaim that seeks recovery of sums PPM has refused to pay pursuant to the Exchange Agreement.  The Company denies all claims.  The dispute was presented to the arbitrator in August 2005.  The Company cannot predict the outcome of the decision.

 

41

 

 

 

**Ongoing Litigation**

 

The Company is subject to various other legal proceedings, claims and litigation which arise in the ordinary course of operations.  In the opinion of management, the amount of liability, if any, with respect to these actions would not materially affect the financial position or results of operations of the Company.

 

**(11)**

**DIVIDEND OF SUBSIDIARY STOCK AND DISCONTINUED OPERATIONS**

 

During the quarter ended March 31, 2003, the Company distributed a dividend of subsidiary stock to its parent company, Black Hills Corporation (Parent).  The dividend consisted of 10,000 common shares of Black Hills Generation, Inc., formerly known as Black Hills Energy Capital, Inc., (Generation), which represents 100 percent ownership of Generation.  The Company therefore no longer operates in the independent power production business.  As a result, the Company no longer has any subsidiaries and operates only in the electric utility business.  The Company’s investment in Generation at the time of the distribution was $46.5 million, including approximately $29.0 million of cash held at Generation. 

 

The disposition was accounted for under the provisions of SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (SFAS 144).  Accordingly, results of operations have been classified as “Discontinued operations, net of income taxes” in the accompanying Statements of Income, and prior periods have been restated.  For business segment reporting purposes, Generation’s business results were previously included in the segment “Independent Power Production.”
