General


We are a regulated electric utility serving customers in South Dakota, Wyoming and Montana.  We are incorporated in South Dakota and began providing electric utility service in 1941.  We are a wholly-owned subsidiary of the publicly traded Black Hills Corporation.


Unless the context otherwise requires, references in this Form 10-K to “the"the Company,” “we,” “us”" "we," "us" and “our”"our" refer to Black Hills Power, Inc.


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 to Parent, and overall performance and growth.


Distribution and Transmission

Distribution and Transmission

Distribution and Transmission..  Our distribution and transmission system serves approximately 66,00066,900 electric customers, with an electric transmission system of 4971,007 miles of high voltage lines (greater than 69 KV) and 2,8342,403 miles of lower voltage lines.  In addition, we jointly own 47 miles of high voltage lines with Basin Electric.  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 91%90% of our retail electric revenues in 20082009 were generated in South Dakota.  We are subject to regulation by the SDPUC, the WPSC and the MTPSC.


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, 20082009 was comprised of 25%29% commercial, 20%23% residential, 11%12% contract wholesale, 27%16% wholesale off-system, 9%10% industrial and 8%10% municipal sales and other revenue. Approximately 80% of our large commercial and industrial customers are provided service under long-term contracts.

     We are subject to regulation by the SDPUC, the WPSC and the MTPSC. In December 2006, we received an order from the SDPUC approving a 7.8% increase in retail rates and the addition of tariff provisions for automatic adjustments of rates for changes in energy, fuel and transmission costs effective January 1, 2007. The cost adjustments require us to absorb a portion of power cost increases, depending in part on earnings on certain short-term wholesale sales of electricity. Absent certain conditions, the order also restricts us from requesting an increase in base rates that would go into effect prior to January 1, 2010.

7



·We own 35% and Basin Electric owns 65% of a transmission tie that provides an interconnection between the Western and Eastern transmission grids, enabling access to both the WECC region in the West, and the MAPP region in the East.  Our system is located in the WECC region.  The total transfer capacity of the tie is 400 MW - 200 MW from West to East and 200 MW from East to West.  This transmission tie allows us to buy and sell energy in the Eastern interconnection without having to isolate and physically reconnect load or generation between the two electrical transmission grids.  The transmission tie 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 MW 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.


·

We have firm point-to-point transmission access to deliver up to 50 MW of power on PacifiCorp’sPacifiCorp's transmission system to wholesale customers in the Western region from 2007 through 2023.

·

We have firm network transmission access to deliver power on PacifiCorp’sPacifiCorp's system to Sheridan, Wyoming to serve our power sales contract with MDU through 2016, with the right to renew pursuant to the terms of PacifiCorp’sPacifiCorp's transmission tariff.


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


An agreement under which we supply up to 74 MW of capacity and energy to MDU for the Sheridan, Wyoming electric service territory through the end of 2016.  The sales to MDU have been integrated into our control area and are considered part of our firm native load.  In accordance withThis agreement permitted MDU the terms of the agreement, MDU has an option to participate in the ownership of the Wygen III plant that is currently being constructed.  In April 2009, MDU has notified usexercised this option and purchased a 25% ownership interest in Wygen III.  In conjunction with the ownership interest transaction, the agreement to supply capacity and energy through 2016 was modified.  The agreement now provides that once in commercial operation, the first 25 MW of its intentions to exercise their option to participatethe required 74 MW will be supplied from MDU's ownership interest in theWygen III.  During periods of reduced production at Wygen III, project and we expect to renegotiate the power sales agreement to reduce the energy and capacity supplied by us under the agreement;or during periods when Wygen III is offline, MDU will be provided with its 25 MW from our other generation facilities or from system purchases;


An agreement with the City of Gillette, Wyoming, to provide the City its first 23 MW of capacity and energy annually.  The sales to the City of Gillette have been integrated into our control area and are considered part of our firm native load.  The agreement renews automatically and requires a seven yearseven-year notice of termination.  As of December 31, 2008,2009, neither party to the agreement had given a notice of termination; and


·

An agreement under which we supply 20 MW of energy and capacity to MEAN under a contract that expires in 2013.2023.  This contract is unit-contingent based on the availability of our Neil Simpson II plant.and Wygen III plants, with capacity purchase decreasing to 15 MW in 2018, 12 MW in 2020 and 10 MW in 2022.  The unit-contingent capacity amounts from Wygen III and Neil Simpson II are as follows

:


2010-2017   20 MW - 10 MW contingent on Wygen III and 10 MW contingent on Neil Simpson II
2018-2019   15 MW - 10 MW contingent on Wygen III and 5 MW contingent on Neil Simpson II
2020-2021   12 MW - 6 MW contingent on Wygen III and 6 MW contingent on Neil Simpson II
2022-2023   10 MW - 5 MW contingent on Wygen III and 5 MW contingent on Neil Simpson II; and

·In July 2009, we entered into a five-year PPA with MEAN.  The contract commences the month following the onset of commercial operations of Wygen III.  Under this contract, MEAN will purchase 5 MW of unit-contingent capacity from Neil Simpson II and 5 MW of unit-contingent capacity from Wygen III.


Regulated Power Plants and Purchased Power.Power.  Our electric load is primarily served by our generating facilities in South Dakota and Wyoming, which provide 434 MW of generating capacity, with the balance supplied under purchased power and capacity contracts.  Approximately 50% of our capacity is coal-fired, 39%1% is oil- or gas-fired, and 11%49% is supplied under the following purchased power contracts:


·A power purchase agreementPPA with PacifiCorp expiring in 2023, involving the purchase by us of 50 MW of coal-fired baseload power;


·

A reserve capacity integration agreement with PacifiCorp expiring in 2012, which makes available to us 100 MW of reserve capacity in connection with the utilization of the Ben French Combustion Turbine units;


·

A 20-year power purchase agreementPPA with Cheyenne Light expiring in 2028, under which we will purchase up to 20 MW of renewablewind energy through Cheyenne Light’sLight's agreement with Happy Jack Wind Farms, LLC;Jack;

·A 20-year PPA with Cheyenne Light expiring in 2029, under which we will purchase up to 20 MW of wind energy through Cheyenne Light's agreement with Silver Sage; and


·

A Generation Dispatch Agreement with Cheyenne Light that requires the Companyus to purchase all of Cheyenne Light’sLight's excess energy.


Since 1995, we have been a net producer of energy.  We reached our 20082009 peak system load of 409392 MW in August 2008December 2009 with an average system load of 255 MW for the year ended December 31, 2008.2009.  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.  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 primarily in the WECC and MAPP regions.  Our 294 MW of low-cost, coal-fired resources supports most of our native load requirements and positions us for these wholesale off-system sales.

Regulations


Rate Regulation


Rates for our retail electric service are subject to regulation by the SDPUC for customers in South Dakota, the WPSC for customers in Wyoming and the MTPSC for customers in Montana.  Any changes in retail rates are subject to approval by the respective regulatory body.  We have rate adjustment mechanisms in Montana and South Dakota which provide for pass-through of certain costs related to the purchase, production and/or transmission of electricity.  We are also subject to the jurisdiction of FERC with respect to accounting practices and wholesale electricity sales.  We have been granted market-based rate authority by the FERC and are not required to file cost-based tariffs for wholesale electric rates.  Rates charged by us for use of our transmission system are subject to regulation by the FERC.


In South Dakota, we have three adjustment mechanisms:  transmission, steam plant fuel and conditional energy cost adjustment.  The transmission and steam plant fuel adjustment clauses will either pass along or give credits back to South Dakota customers based on actual costs incurred on a yearly basis.  The conditional energy cost adjustment relates to purchased power and natural gas used to generate electricity.  These costs are subject to $2.0 million and $1.0 million cost bandsthresholds where we absorb the first $2.0 million of increased costs or retainsretain the first $1.0 million in savings.  Beyond these thresholds, costs or refunds begin to be passed on to South Dakota customers through annual calendar-year filings.

9



Rate Increase Settlement.  On February 10, 2009, FERC approved a formulaic approach to the method used to determine the revenue component of our open access transmission tariff, and increased our annual transmission revenue requirement by approximately $3.8 million.  The revenue requirement is based on an equity return of 10.8%, and a capital structure consisting of 57% equity and 43% debt.  The new rates had an effective date of January 1, 2009.


Environmental Regulations


We are subject to federal, state and local laws and regulations with regard to air and water quality, waste disposal, federal health and safety regulations, and other environmental matters.  We have incurred, and expect to incur, capital, operating and maintenance costs to comply with the operations of our plants.  While the requirements are evolving, it is virtually certain that environmental requirements placed on the operations will continue to be more restrictive.


Regulatory Accounting

As it pertains to the


We follow accounting for our regulated utility operations we follow SFAS 71 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 accounting criteria for following SFAS 71,regulated operations, the accounting impact to us could be an extraordinary non-cash charge to operations of an amount that could be material.


New Accounting Pronouncements


See Note 1 of our Notes to Financial Statements in this Annual Report on Form 10-K for information on new accounting standards adopted in 20082009 or pending adoption.

ITEM 1A.

RISK FACTORS


The following specific risk factors and other risk factors that we discuss in our periodic reports filed with the SEC 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.


We may not raise our retail rates without prior approval of the SDPUC, WPSC or the MTPSC.  If we seek rate relief, we could experience delays, reduced or partial rate recovery, or disallowances in rate proceedings.

Because


Our regulated electricity operations are subject to cost-of-service regulation and earnings oversight.  This regulatory treatment does not provide any assurance as to achievement of desired earnings levels.  Our rates are regulated on a state-by-state basis by the relevant state regulatory authorities based on an analysis of our costs, as reviewed and approved in a regulatory proceeding.  The rates that we are generally unableallowed to increasecharge may or may not match our base rates without prior approval from the SDPUC, the WPSC,related costs and the MTPSC, ourallowed return on invested capital at any given time.  Our returns could be threatened by plant outages, machinery failure,failures, increased purchased power costs, acts of nature, acts of terrorism or other unexpected events over which we have no control that could cause operatingour costs to increase and operating margins to decline.  While we have cost pass-through mechanisms in place that allowrate regulation is premised on the full recovery of increasedprudently incurred costs relatedand a reasonable rate of return on invested capital, there can be no assurance that the state public utility commissions will judge all of our costs, including our borrowing and debt service costs, to have been prudently incurred or that the regulatory process in which rates are determined will always result in rates that will produce a full recovery of our costs and the return on invested capital allowed by the applicable state public utility commission.

To some degree, we are permitted to recover certain costs (such as increased fuel, purchased power transmission and natural gas, there is no guarantee that all increases in these costs will be recovered. Additionally, our general operating costs and investments are subjecttransmission, as applicable) without having to file a rate case.  To the reviewextent we pass through such costs to customers and a state public utility commission subsequently determines that such costs should not have been paid by customers, we may be required to refund such costs to customers.  Any such costs not recovered through rates, or any such refund, could negatively affect our revenues, cash flows and results of the SDPUC, the WPSC and the MTPSC. These commissions could find certain costs or investments are not prudent and not recoverable in our rates, thus negatively affecting our revenues.

operations.

The recent global financial crisis has made the credit markets less accessible and created a shortage of available credit.  WeShould a similar financial crisis occur in the future, we may therefore, be unable to obtain the financing needed to refinance debt, fund planned capital expenditures or otherwise execute our operating strategy.


Our ability to execute our operating strategy is highly dependent upon our access to capital.  Historically, we have addressed our liquidity needs (including funds required to make scheduled principal and interest payments, refinance debt and fund working capital and planned capital expenditures) with operating cash flow, borrowings under credit facilities, and proceeds of debt offerings and equity offerings.proceeds from asset sales.  Our ability and the ability of our Parent, to access the capital markets and the costs and terms of available financing depend on many factors, including changes in our credit ratings, changes in the federalFederal or state regulatory environment affecting energy companies, volatility in commodity or electricity prices and general economic and market conditions.

Recent

Our financial distress withinperformance depends on the global economy has caused significant disruption in the credit markets.  Among other things, long-term interest rates on debt securities have increased significantly and the volume of equity and debt security issuances has decreased.  Recent actions taken by the United States government, the Federal Reserve and other governmental and regulatory bodies may be insufficient to stabilize these markets.  The longer such conditions persist, the more significant the implications become for us, including the possibility that adequate capital may not be available (or available on reasonable commercial terms) for us to refinance indebtedness. Among other things, alternatives could include deferring portionssuccessful operations of our planned capital expenditure program, selling assets or issuing equity. The failure to consummate refinancings, and any actions taken in lieu of such refinancings, could have a material adverse effect on our results of operations, cash flows and financial condition.

facilities.


Operating electric generating facilities involves risks, including:

·Operational limitations imposed by environmental and other regulatory requirements.

·Interruptions to supply of fuel and other commodities used in generation.

·Breakdown or failure of equipment or processes.

·Inability to recruit and retain skilled technical labor.

·Labor relations.  Renewal negotiations of the collective bargaining agreement are planned in early 2010.

Disrupted transmission and distribution.  We depend on transmission and distribution facilities, including those operated by unaffiliated parties, to deliver the electricity that we sell to our retail and wholesale customers.  If transmission is interrupted, our ability to sell or deliver product and satisfy our contractual obligations may be hindered.

Regulatory commissions may refuse to approve some or all of the utility rate increases we have requested or may request in the future, or may determine that amounts passed through to customers were not prudently incurred and are, therefore, not recoverable.


Our regulated electricity operations are subject to cost-of-service regulation and earnings oversight.oversight from federal and state utility commissions.  This regulatory treatment does not provide any assurance as to achievement of desired earnings levels.  Our rates are regulated on a state-by-state basis by the relevant state regulatory authorities based on an analysis of our costs, as reviewed and approved in a regulatory proceeding.  The rates that we are allowed to charge may or may not match our related costs and allowed return on invested capital at any given time.  While rate regulation is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital, there can be no assurance that the state public utility commissions will judge all of our costs, including our borrowing and debt service costs, to have been prudently incurred or that the regulatory process in which rates are determined will always result in rates that will produce a full recovery of our costs and the return on invested capital allowed by the applicable state public utility commission.


To some degree, we are permitted to recover certain costs (such as increased fuel and purchased power costs, as applicable) without having to file a rate case.  To the extent we are able to pass through such costs to ratepayersour customers and a state public utility commission subsequently determines that such costs should not have been paid by ratepayers;our customers; we may be required to refund such costs to ratepayers.our customers.  Any such costs not recovered through rates, or any such refund, could negatively affect our revenues, cash flows and results of operations.

The recent global financial crisis has also increasedaffected our counterparty credit risk.


As a consequence of the global financial crisis, the creditworthiness of many of our contractual counterparties (particularly financial institutions) has deteriorated. As the creditworthiness of our counterparties deteriorates, we face increased exposure to counterparty credit default.


We have established guidelines, controls and limits to manage and mitigate credit risk.  For our energy marketing, production and generation activities, we seek to mitigate our credit risk by conducting a majority of our business with investment grade companies, setting tenor and credit limits commensurate with counterparty financial strength, obtaining netting agreements and securing our credit exposure with less creditworthy counterparties through parent company guarantees, prepayments, letters of credit and other security agreements.  Although we aggressively monitor and evaluate changes in our counterparties’counterparties' credit statusquality and adjust the credit limits based upon such changes, in the customer’s creditworthiness, our credit guidelines, controls and limits may not protect us from increasing counterparty credit risk under today’s stressed financial conditions.risk.  To the extent the financial crisis causes our credit exposure to contractual counterparties to increase materially, such increased exposure could have a material adverse effect on our results of operations, cash flows and financial condition.


National and regional economic conditions may cause increased late payments and uncollectible accounts, which would reduce earnings and cash flows.


A prolonged recession may lead to an increase in late payments from retail and commercial utility customers, as well as our non-utility customers (including marketing counterparties).  If late payments and uncollectible accounts increase, earnings and cash flows from our continuing operations may be reduced.


Our credit ratings could be lowered below investment grade 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 credit rating on our First Mortgage Bonds is “Baa1”"A3" by Moody’sMoody's, "BBB" by S&P and “BBB”A- by S&P.Fitch.  Any reduction in our ratings by Moody’s or S&Pthe rating agencies 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.

National and regional economic conditions may cause increased late payments and uncollectible accounts, which would reduce earnings and cash flows.

A prolonged recession may lead to an increase in late payments from retail and commercial utility customers. If late payments and uncollectible accounts increase, earnings and cash flows from our utilities may be reduced.

Construction, expansion, refurbishment and operation of power generating and transmission 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;


·

Contract restrictions upon the timing of scheduled outages;


·

Cost of supplying or securing replacement power during scheduled and unscheduled outages;


·

The unavailability or increased cost of equipmentequipment;

·The inability and labor supply;

cost of recruiting and retaining skilled labor;

·

Supply interruptions, work stoppages and labor disputes;


·

Capital and operating costs to comply with increasingincreasingly stringent environmental laws and regulations;


·

Opposition by members of the public or special-interest groups;


·

Weather interferences;


·

Unexpected engineering, environmental and geological problems; and


·

Unanticipated cost overruns.


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 reduce revenues, increase expenses, or cause us to incur 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 timely or adequate to cover lost revenues, increased expenses or liquidated damage payments.



14


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 off-system wholesale electricity sales.  The related power prices are influenced by many factors outside our control, including among other things, fuel prices, transmission constraints, supply and demand, weather, general 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, unpredictable price fluctuations over relatively short periods of time.

13



Our operating results can be adversely affected by milder weather.


Our utility business is a seasonal business and weather patterns can have a material impact on our operating performance.  Demand for electricity is typically greater in the summer and winter months associated with cooling and heating.  Accordingly, our utility operations have historically generated less revenues and income when weather conditions are cooler in the summer and warmer in the winter.   Unusually mild summers and winters therefore could have an adverse effect on our financial condition and results of operations.


Our business is subject to substantial governmental regulation and permitting requirements as well as environmental liabilities, including those we assumed in connection with certain acquisitions.liabilities.  We may be adversely affected if we fail to achieve or maintain compliance with existing or future regulations or requirements, or the potentially high cost of complying with such requirements or addressing environmental liabilities.


Our business is subject to extensive energy, environmental and other laws and regulations of federal, state and local authorities.  We generally must obtain and comply with a variety of regulations, licenses, permits and other approvals in order to operate, which could require significant capital expenditures and operating 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; claims for property damage or personal injury; or environmental clean-up costs.  In addition, existing regulations may be revised or reinterpreted, new laws and regulations may be adopted or become applicable to us or our facilities, which could require additional unexpected expenditures and have a detrimental effect on our business.


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



15


Federal and state laws concerning climate change and air emissions, including emission reduction mandates and renewable energy portfolio standards, may materially increase our generation and production costs and could render some of our generating units uneconomical to operate and maintain.


We own and operate regulated and non-regulated fossil-fuel generating plants in South Dakota Wyoming and Montana.Wyoming.  We are constructingnear completion of another fossil-fuel generating plant in Wyoming.  Air emissions of our fossil-fuel generating plants are subject to federal state and tribalstate regulation.  Recent changes indevelopments under federal and state laws and regulation governing air emissions from fossil-fuel generating plants will likely result in more stringent emission limitations. As

On October 22, 2009, the EPA filed a consent decree with environmentalists in the U.S. District Court for the District of Columbia, requiring the agency to propose a rule directed at coal and oil-fired power plants, setting maximum achievable control technology limits for air toxins, including mercury, by March 2011 and issue a final rule by November 2011.  While we expect this rule will be applicable to certain of our coal-fired units, we are unable to ascertain the full impact until the provisions of the proposed rule are known.

On April 2, 2007, the U.S. Supreme Court issued a decision in the case of Massachusetts v. U.S. Environmental Protection Agency, holding that CO2 and other GHG emissions are pollutants subject to regulation under the motor vehicle provisions of the Clean Air Act.  The case was remanded to the EPA for further rulemaking to determine whether GHG emissions may reasonably be anticipated to endanger public health or welfare, or alternatively, to explain why GHG emissions should not be regulated.  On April 17, 2009, the EPA signed its proposed Endangerment and Cause or Contribute Finding for Greenhouse Gases under Section 202 of the Clean Air Act.  Although this proposal does not specifically address stationary sources, such as power generation plants, the general endangerment finding relative to GHGs could support such a proposal by the EPA for stationary sources.  On October 30, 2009, the EPA published final rules regarding a mandatory GHG reporting regimen, the purpose of which would be to collect data to inform future policy and regulatory decisions.

In addition, the EPA published in the October 27, 2009, Federal Register a proposed rule that would tailor the major source applicability thresholds for GHG emissions under the PSD and Title V programs of the Clean Air Act and set a PSD significance level for GHG emissions.  EPA states this rule is necessary because they expect to soon promulgate regulations under the Clean Air Act to control GHG emissions and as a result, trigger PSD and Title V applicability requirements.  This proposed rule would phase in the applicability thresholds for both the PSD and Title V programs for sources of GHG emissions.  The first phase, which would last six years, would establish a temporary level for the PSD and Title V applicability thresholds at 25,000 tons per year on a carbon dioxide equivalent basis and would also establish temporary PSD significance levels.  All our generating units would exceed this threshold and if the pending rule to control GHG emissions is published and finalized, we would be required upon Title V permit renewal, to evaluate options for reducing GHG emissions, to possibly include a Best Available Control Technology review that could result in more stringent emissions control practices and technologies.  In the second phase of this proposed rule, EPA would within five years of the rule being final, review the first phase and promulgate revised applicability and significance level thresholds as appropriate.


16


Finally, federal legislation is currently under consideration in the U.S. Congress, including H.R. 2454, "the American Clean Energy and Security Act of 2009," which was approved by the U.S. House of Representatives on June 26, 2009.  This legislation would affect electric generation and electric and natural gas distribution companies.  H.R. 2454 also proposes a national renewable electricity standard, which would implement a phased process ultimately mandating that 20% of electricity sold by retail suppliers be met by energy efficiency improvements and renewable energy resources by 2020.

The climate bill under consideration in the U.S. Senate is S.1733, "the Clean Energy Jobs and American Power Act."  S.1733 was passed by the Environment and Public Works Committee November 5, 2009, but is not expected to be brought to the Senate floor in its current form.  Other committees with jurisdiction include Finance, Energy and Natural Resources, Commerce, Agriculture, and Foreign Relations.  The Senate Energy and Natural Resources Committee passed S.1462, "the American Clean Energy Leadership Act of 2009," on July 16, 2009, which would establish a 15% Renewable Electricity Standard by 2021.  If the Senate were to act in 2010, it is likely the climate change particularly with respectand renewable electricity standard portions would be combined into one bill.

Due to CO2uncertainty as to the final outcome of federal climate change legislation, or regulatory changes under the Clean Air Act, we cannot definitively estimate the effect of GHG regulation on our results of operations, cash flows or financial position.  The impact of GHG legislation or regulation upon our company will depend upon many factors, including but not limited to the timing of implementation, the GHG sources that are regulated, the overall GHG emissions cap level, and the availability of technologies to control or reduce GHG emissions.  If a "cap and trade" structure is implemented, the impact will also be affected by fossil-fuel generating plants, receives increased attention, additional or morethe degree to which offsets are allowed, the allocation of emission allowances to specific sources, and the affect of carbon regulation on natural gas and coal prices.

More stringent emissionGHG emissions limitations or other energy efficiency requirements, could be imposed. These limitations or other requirementshowever, could require us to incur significant additional costs relating to, among other things, the installation of additional emission control equipment, the acceleration of capital expenditures, the purchase of additional emissions allowances or offsets, the acquisition or development of additional energy supply from renewable resources, and the closure of certain generating facilities.  To the extent our regulated fossil-fuel generating plants are included in rate base, we will attempt to recover costs associated with complying with emission standards or other requirements.  We willBlack Hills Non-regulated Holdings would also attempt to recover the emission compliance costs of ourtheir non-regulated fossil-fuel generating plants from utility and other purchasers of the power generated by ourthe affiliated non-regulated power plants.  Any unrecovered costs could have a material impact on our results of operations and financial condition.  In addition, future changes in environmental regulations governing air emissions could render some of our power generating units more expensive or uneconomical to operate and maintain.

14



We own regulated electric utilities that serve customers in South Dakota, Wyoming and Montana.  Montana has adopted mandatory renewable portfolio standards that require electric utilities to supply a minimum percentage of the power delivered to customers from renewable resources (e.g., wind, solar, biomass) by a certain date in the future.  These renewable energy portfolio standards have increased the power supply costs of our electric operations.  If these states increase their renewable energy portfolio standards, or if similar standards are imposed by the other states in which we operate electric utilities, our power supply costs will further increase (and could increase materially).increase. Although we will seek to recover these higher costs in rates, any unrecovered costs could have a material negative impact on our results of operations and financial condition.



17


We may be vulnerable to cyber attacks and terrorism.

Man-made problems such as computer viruses, terrorism, theft and sabotage, may disrupt our operations and harm our operating results.  We operate in a highly regulated industry that requires the continued operation of sophisticated information technology systems and network infrastructure.  Our technology systems may be vulnerable to disability, failures or unauthorized access due to hacking, viruses, acts of war or terrorism and other causes.  If our technology systems were to fail or be breached and we were unable to recover in a timely manner, we may be unable to fulfill critical business functions and sensitive, confidential and other data could be compromised, which could have a material adverse effect on our results of operations, financial condition and cash flows.  In addition, our generation plants, fuel storage facilities, transmission and distribution facilities may be targets of terrorist activities that could disrupt our ability to produce or distribute some portion of our energy products.

Ongoing changes in the United States electric utility industry, including state and federal regulatory changes, a potential increase in the number or geographic scale 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 EPAEnergy Policy Act of 2005 and the repeal of the PUHCA;


·

Industry consolidation;


·

Consumer demands;


·

Transmission constraints;


·

Renewable resource supply requirements;


·Resistance to the siting of utility infrastructure or to the granting of right-of-ways;

·Technological advances; and


·

Greater availability of natural gas-fired power generation, and other factors.

The


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.  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 negativelyadversely affect our ability to expand our asset base.

financial condition or results of operations.



18


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 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.

15



Governmental authorities may assess penalties on us if it is determined that we have not complied with environmental laws and regulations.


If we fail to comply with environmental laws and regulations, even if caused by factors beyond our control, that failure may result in the assessment of civil or criminal penalties and fines against us.  Recent lawsuits by the EPA and various states filed against others within industries in which we operate highlight the environmental risks faced by generating facilities, in general, and coal-fired generating facilities in particular.


Increased risks of regulatory penalties could negatively impact our business.

EPA


The Energy Policy Act of 2005 increased FERC’sFERC's civil penalty authority for violation of FERC statutes, rules and orders.  FERC can now impose penalties of $1.0 million per violation, per day.  Many rules that were historically subject to voluntary compliance are now mandatory and subject to potential civil penalties for violations.  If a serious violation did occur, and penalties were imposed by FERC, it could have a material adverse effect on our operations or our financial results.


Increasing costs associated with our defined benefit retirement plans may adversely affect our results of operations, financial position or liquidity.


We have defined benefit pension plans that cover a substantial portion of our employees.  Assumptions related to future costs, return on investments, interest rates and other actuarial assumptions have a significant impact on our funding requirements related to these plans.  These estimates and assumptions may change based on actual return on plan assets, changes in interest rates and any changes in governmental regulations.  In addition, the Pension Protection Act of 2006 changed the minimum funding requirements for defined benefit pension plans beginning in 2008.


Increasing costs associated with our health care plans may adversely affect our results of operations, financial position or liquidity.


The costs of providing health care benefits to our employees and retirees have increased substantially in recent years.  We believe that our employee benefit costs, including costs related to health care plans for our employees and former employees, will continue to rise.  The increasing costs and funding requirements associated with our health care plans may adversely affect our results of operations, financial position or liquidity.



19


An effective system of internal control may not be maintained, leading to material weaknesses in internal control over financial reporting.


Section 404 of the Sarbanes-Oxley Act of 2002 requires management to make an assessment of the design and effectiveness of internal controls.  During their assessment of these controls, management or our independent auditors may identify areas of weakness in control design or effectiveness, which may lead to the conclusion that a material weakness in internal control exists.

2009 Compared to 2008

Net income increased $0.4 million or 2% primarily due to:

·$6.5 million increase in other margins primarily due to an increase in transmission rates effective January 1, 2009;

·Increased other income primarily due to a $2.2 million increase of AFUDC-equity, attributable to the ongoing construction of Wygen III; and

·Income tax expense decreased $1.2 million primarily due to a decrease in pre-tax net income and the favorable tax impact as a result of the increase in AFUDC-equity.

Partially offsetting the increases to earnings was the following:

·Margins from wholesale off-system sales decreased $7.6 million due to a 46% decrease in energy prices and a 6% decrease in total MWh sold in the power markets;

·Increase in net interest expense of $1.1 million primarily due to a new debt issuance; and

·A $1.0 million decrease in retail and wholesale margins primarily due to increased coal costs and a 2% decrease in MWh sold related to lower cooling degree days.

22


2008 Compared to 2007


Net income decreased $2.1 million or 9% primarily due to:


·A $2.6 million reduction in retail and wholesale sales margins due to increased fuel and purchased power costs, primarily due to increased coal costs and scheduled and unscheduled outages at Ben French, Osage and Neil Simpson I coal-fired plants.  The duration of the Ben French outage was three months as we accelerated the completion of maintenance projects that were originally scheduled for this plant in 2009;


·

Increased operating expenses due to increased repairs and maintenance expenses and labor overhead costs; and


·

Increased administrative and general expenses of $1.9 million due to an increase in the workers’workers' compensation reserve.


Partially offsetting the decreases to earnings was the following:

Partially offsetting the decreases to earnings was the following:

·

Margins from wholesale off-system sales increased $1.3 million.  Total MWhsMWh increased 58% as we were able to take advantage of favorable market conditions and high MIDC pricing due to below normal temperatures; and


·

Income related to a $5.3 million increase of AFUDC, primarily attributable to the ongoing construction of Wygen III.


Rate Increase Requests.  On October 19,

2009, we filed a rate case with the WPSC requesting an electric revenue increase to recover costs associated with Wygen III and other generation, transmission and distribution assets and increased operating expenses incurred since 1995.  We are seeking a $3.8 million, or approximately 38.95%, increase in annual utility revenues and anticipate that the new rates will be effective for our Wyoming customers on or around July 1, 2010, although recovery could be delayed until August 2010 as part of the regulatory process.  The proposed rate increase is subject to approval by the WPSC and we cannot predict the outcome of this rate filing request.


On September 30, 2009, we filed a rate case with the SDPUC requesting an electric revenue increase to recover costs associated with Wygen III and other generation, transmission and distribution assets and increased operating expenses incurred during the past four years.  We are seeking a $32.0 million, or approximately 26.6%, increase in annual utility revenues.  The final order from the SDPUC is not expected by April 1, 2010.  On March 1, 2010, we filed a petition with the SDPUC requesting an interim rate increase of $24.0 million, or 20%, for South Dakota utility customers.  The SDPUC approved the request for interim rates on March 9, 2010 effective April 1, 2010.  The proposed rate increase is subject to approval by the SDPUC and we cannot predict the outcome of this rate filing request.



23


2007 Compared to 2006

Income from continuing operations increased 33% primarily due to:

     Retail sales revenues increased 11% due to an increase in rates that went into effect on January 1, 2007 and a 3% increase in MWh sold;

     Purchased power decreased 9% due to an 18% decrease in MWh purchased, partially offset by a 10% increase in price per MWh;

     Margins from wholesale off-system sales increased 7%; and

     Lower property taxes due to lower assessed property valuations.

Partially offsetting the increases to earnings was the following:

     Fuel expense increased 23% due to increased coal prices and the use of higher cost gas generation to meet demand requirements.

Rate Increase Settlement.  On February 10, 2009, FERC approved a formulaic approach to the method used to determine the revenue component of our open access transmission tariff, and increased our annual transmission revenue requirement by approximately $3.8 million.  The revenue requirement is based on an equity return of 10.8%, and a capital structure consisting of 57% equity and 43% debt.  The new rates had an effective date of January 1, 2009.


In December 2006, we received an order from the SDPUC, effective January 1, 2007, approving a 7.8% increase in retail rates and the addition of tariff provisions for automatic cost adjustments.  The cost adjustments require us to absorb a portion of power cost increases partially depending on earnings from certain short-term wholesale sales of electricity.  Absent certain conditions, the order also restricts us from requesting an increase in base rates that would go into effect prior to January 1, 2010.  South Dakota retail customers account for approximately 91%90% of our total retail revenues.


Wygen III Power Plant Project


In March 2008, we received final regulatory approval for construction of Wygen III.  Construction began immediately and the 110 MW coal-fired base load electric generation facility is expected to take 24 to 30 months to complete.be completed by April 2010.  The expected cost of construction is approximately $255 million, which includes estimates of AFUDC.  We expectIn April 2009, we sold a 25% ownership interest to retain ownership of 75 MWMDU.  At closing, MDU made a payment to us for its 25% share of the facility’s capacity with MDU currently being expectedcosts to take ownershipdate for the on-going construction of the remaining 25 MW.facility.  MDU will continue to reimburse us monthly for its 25% of the total costs paid to complete the project.  We will retain responsibility for operation of the facility with a life-of-plant site lease, and operations and coal supply agreements in place with MDU.

Management's Report on Internal Control over Financial Reporting


We are responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended.Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.


All internal control systems, no matter how well designed, have inherent limitations.  Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.  Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.


Under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2008,2009, based on the criteria set forth in Internal Control - Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission.  This evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion on this evaluation.  Based on our evaluation we have concluded that our internal control over financial reporting was effective as of December 31, 2008.2009.


This annual report does not include an attestation report of the Company’sour registered public accounting firm regarding internal control over financial reporting.  Management’sManagement's report was not subject to attestation by the Company’sour registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit the Companyus to provide only management’smanagement's report in this annual report.

December 31, 2009, 2008 2007 and 2006

2007

(1)

BUSINESSDESCRIPTIONANDSUMMARYOFSIGNIFICANTACCOUNTINGPOLICIES


Business Description


Black Hills Power, Inc. (the Company) is an electric utility serving customers in South Dakota, Wyoming and Montana.  The Company isWe are a wholly-owned subsidiary of BHC or the Parent, a public registrant listed on the New York Stock Exchange.


Basis of Presentation


The financial statements include the accounts of Black Hills Power, Inc. and also the Company’sour ownership interests in the assets, liabilities and expenses of itsour jointly owned facilities (Note 3).

  Certain prior years' data presented in the financial statement have been reclassified to conform to the current year presentation.  The Balance Sheet has been modified to reflect "Regulatory assets, current," which had been previously included in Other current assets and "Regulatory liabilities, current," which was previously included in Accrued liabilities.  The Statement of Cash Flows for December 31, 2008 and 2007 has been modified within Net cash provided by operating activities to reflect "Regulatory assets," which was previously included in Other operating activities and "Regulatory liabilities," which was previously included in Other operating activities.  The Statement of Cash Flows for December 31, 2008 and 2007 has been modified within Net cash provided by operating activities to reflect “Other non-cash” which was previously included in Other operating activities.


Use of Estimates


The preparation of financial statements in conformity with GAAP 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, unbilled revenues, long-lived asset values and useful lives, asset retirement obligations, employee benefits plans and contingency accruals.  Actual results could differ from those estimates.


Regulatory Accounting

The Company’s


Our 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 FERC.

The Company’s


Our regulated utility operations follow the provisions of SFAS 71accounting standards for regulated operations and itsour financial statements reflect the effects of the different ratemaking principles followed by the various jurisdictions regulating itsour 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’sour regulated generation operations.  In the event the Company determineswe determine that itwe no longer meetsmeet the criteria for following SFAS 71,accounting standards for regulated operations, the accounting impact to the Companyus could be an extraordinary non-cash charge to operations in an amount that could be material.

28


As of December 31, 2009 and 2008, we had $22.6 million and $24.6 million, respectively, in net regulatory assets for which we recover the costs, but we do not earn a return.

Regulatory assets are primarily recorded for the probable future revenue to recover the costs associated with defined benefit postretirement plans, future income taxes related to the deferred tax liability for the equity component of AFUDC of utility assets and unamortized losses on reacquired debt.  To the extent that energy costs are under-recovered or over-recovered during the year, they are recorded as a regulatory asset or liability, respectively.  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, gains associated with regulated utilities’utilities' defined benefit postretirement plans and the cost of removal for utility plant, recovered through the Company’sour electric utility rates.  Regulatory assets are included in OtherRegulatory assets, current assets and Other assets, Regulatory assets, non-current on the accompanying Balance Sheet.  Regulatory liabilities are included in AccruedRegulatory liabilities, current and Deferred credits and other liabilities, Regulatory liabilities, non-current on the accompanying Balance Sheet.


Allowance for Funds Used During Construction


AFUDC represents the approximate composite cost of borrowed funds and a return on capital used to finance a project.  AFUDC for the years ended December 31, 2009, 2008 and 2007 and 2006 was $10.2 million, $6.2 million $0.9 million, and $0.6$0.9 million, respectively.  The equity component of AFUDC for 2009, 2008 and 2007 and 2006 was $5.8 million, $3.6 million and $0.6 million, and $0.4, respectively.  The borrowed funds component of AFUDC for 2009, 2008 and 2007 and 2006 was $4.4 million, $2.6 million $0.3 million and $0.2$0.3 million, respectively.  The equity component of AFUDC is included in Other income, (expense), and the borrowed funds component of AFUDC is netted in Interest expense on the accompanying Statements of Income.


Cash Equivalents

The Company considers


We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents.

33


Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts which reflects our best estimate of potentially uncollectible trade receivables.  We regularly review our trade receivables allowances by considering such factors as historical experience, credit-worthiness, the age of the receivable balances and current economic conditions that may affect the ability to pay.

Following is a summary of receivables at December 31 (in thousands):

 2009  2008 
      
Accounts receivable trade$14,703  $18,860 
Unbilled revenues 5,547   5,391 
Total accounts receivable – customers 20,250   24,251 
Allowance for doubtful accounts (259)  (370)
Net accounts receivable$19,991  $23,881 

Materials, Supplies and Fuel


Materials, supplies and fuel used for construction, operation and maintenance purposes are generally stated on a weighted-average cost basis.  To the extent fuel has been designated as the underlying hedged item in a “fair value”"fair value" hedge transaction, those volumes are stated at market value using published industry quotations.  As of December 31, 20082009 and 2007,2008, there were no market adjustments related to fuel.


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.  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.  Removal costs associated with non-legal obligations are reclassified from accumulated depreciation and reflected as regulatory liabilities.  Ordinary 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 2.8% in 2009, 3.2% in 2008 and 3.1% in 2007 and 3.0% in 2006.

2007.  Based on a rate study, the new composite rate of 2.8% went into effect August 2009.



34


Derivatives and Hedging Activities

The Company, from


From time to time utilizeswe utilize risk management contracts including forward purchases and sales and fixed-for-float swaps to hedge the price of fuel for itsour combustion turbines, maximize the value of itsour natural gas storage or fix the interest on itsour variable rate debt.  Contracts that qualify as derivatives under SFAS 133,accounting standards for derivatives, and that are not exempted such as normal purchase/normal sale, are required to be recorded in the balance sheet as either an asset or liability, measured at its fair value.  SFAS 133 requiresAccounting standards for derivatives require that changes in the derivative instrument’sinstrument's fair value be recognized currently in earnings unless specific hedge accounting criteria are met.

SFAS 133


Accounting standards for derivatives allows hedge accounting for qualifying fair value and cash flow hedges.  SFAS 133 provides that the gainGain 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 should be recognized currently in earnings in the same accounting period.  SFAS 133 provides thatConversely, the effective portion of the gain or loss on a derivative instrument designated and qualifying as a cash flow hedging instrument should be reported as a component of other comprehensive income, net of tax, 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.

30



Impairment of Long-Lived Assets

The Company


We periodically evaluatesevaluate whether events and circumstances have occurred which may affect the estimated useful life or the recoverability of the remaining balance of itsour long-lived assets.  If such events or circumstances were to indicate that the carrying amount of these assets was not recoverable, the Companywe 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 Companywe would recognize an impairment loss.  No impairment loss was recorded during 2009, 2008 2007 or 2006.

2007.


Income Taxes

The Company uses


We use 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, as well as operating loss and tax credit carryforwards.  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 classifiesWe classify deferred tax assets and liabilities into current and non-current amounts based on the classification of the related assets and liabilities.

The Company files


We file 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.

Recently Adopted Accounting Pronouncements

Standards


FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles, ASC 105

SFAS 157

During September 2006,On July 1, 2009, the FASB issued SFAS 157.Accounting Standards CodificationTM became the source of authoritative GAAP recognized by the FASB to be applied by non-governmental entities.  On the effective date of this Statement, the Codification superseded all then-existing non-SEC accounting and reporting standards.  All other non-SEC accounting literature not included or grandfathered in the Codification became non-authoritative.  This Statement is effective for financial statements issued for interim and annual periods ending after September 15, 2009.


Following this Statement, the FASB will not issue new standards in the form of Statements, FASB Staff Positions, or Emerging Task Force Abstracts.  Instead, it will issue Accounting Standards Updates.  The FASB will not consider Accounting Standards Updates as authoritative in their own right.  Accounting Standards Updates will serve only to update the Codification, provide background information about the guidance, and provide the basis for conclusions on the change(s) in the Codification.

Business Combinations, ASC 805

The ASC for Business Combinations requires that the acquisition method of accounting be used for all business combinations and for an acquirer to be identified for each business combination.  It also establishes principles and requirements for how the acquirer (i) recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree, (ii) recognizes and measures the goodwill acquired in the business combination or a gain from a bargain purchase and (iii) discloses the nature and financial effects of the business combination; and requires restructuring and acquisition-related costs to be expensed.  In addition, if income tax liabilities are settled for an amount other than as previously recorded, such adjustments could affect income tax expense in the period of adjustment.  Effective January 1, 2009, any impact the standard will have on our consolidated financial statements will depend on the nature and magnitude of any future acquisitions we consummate including any tax-related adjustments.

Derivative and Hedging, ASC 815

The ASC for Derivative and Hedging Disclosures includes requirements for enhanced disclosures about derivative and hedging activities and their affect on an entity's financial position, financial performance and cash flows.  Accounting standards for derivatives and hedging encourages, but does not require, disclosures for earlier periods presented for comparative purposes at initial adoption.  Required disclosures for periods subsequent to January 1, 2009 are provided in Note 4.

Fair Value Measurements and Disclosures, ASC 820

The ASC for Fair Value Measurements and Disclosures defines fair value, establishes a framework for measuring fair value in GAAP and expandsexpands disclosures about fair value measurements.  SFAS 157This does not expand the application of fair value accounting to any new circumstances, but applies the framework to other accounting pronouncementsapplicable GAAP that requirerequires or permitpermits fair value measurement.  The Company appliesWe apply fair value measurements to certain assets and liabilities, primarily commodity derivatives.

SFAS 157 is effective



36


Financial Instruments, ASC 825

The ASC for Financial Instruments requires public companies to provide more frequent disclosures about the fair value of their financial instruments for interim and annual periods ending after June 15, 2009.  These disclosures are included in Note 6.

Subsequent Events, ASC 855

The ASC for Subsequent Events establishes general standards of accounting for and disclosures of events that occur after the balance sheet date, but before financial statements are issued or are available to be issued.  These standards and disclosures were applied to our financial statements issued after June 15, 2009.

Employers Accounting for fiscal years beginning after November 15, 2007Defined Benefit Pension and interim periods within those fiscal years. As of January 1, 2008, the Company adopted the provisions of SFAS 157Other Postretirement Plans, ASC 715

The ASC for all assetsEmployer's Accounting for Defined Benefit Pension and liabilities measured at fair value except for non-financial assets and liabilities measured at fair value on a non-recurring basis, as permitted by FSP FAS 157-2. SFAS 157 also requires new disclosures regarding the level of pricing observability associated with instruments carried at fair value. On October 10, 2008, the FASB issued FSP FAS 157-3. It was effective upon issuance including prior periods for which financial statements have not been issued. This FSP clarifies the application of SFAS 157 in a market that is not active. The adoption of SFAS 157 and related FSPs did not have a material impact on the Company’s financial position, results of operations or cash flows.

31


SFAS 158

During September 2006, the FASB issued SFAS 158. This StatementOther Postretirement Plans requires the recognition of the overfunded or underfunded status of defined benefit postretirement plans as an asset or liability in the statement of financial position, recognition of changes in the funded status in comprehensive income, measurement of the funded status of a plan as of the date of the year-end statement of financial position and provides for related disclosures.  The Company applied the recognition provisions of SFAS 158 as of December 31, 2006. Effective for fiscal years ending after December 15, 2008, SFAS 158 requiresthis accounting standard required the measurement of the funded status of the plan to coincide with the date of the year-end statement of financial position.  In accordance with SFAS 158,Therefore, the measurement date for the funded status of the Company’sour pension and other postretirement benefit plans was changed to December 31 from September 30 (see Note 9).

SFAS 159

SFAS 159 establishes a fair value option under which entities can elect to report certain financial assets and liabilities at fair value, with changes in fair value recognized in earnings. SFAS 159 was adopted30.  ASC 715 also provides guidance on January 1, 2008 and did not have an impact on the Company’s financial position, results of operations or cash flows.

Recently Issued Accounting Pronouncements

SFAS 141(R)

In December 2007, the FASB issued SFAS 141(R). SFAS 141(R) requires an acquiring entity to recognize the assets acquired, the liabilities assumed and any non-controlling interests in the acquiree at the acquisition date to be measured at their fair values as of the acquisition date, with limited exceptions specified in the statement. This replaces the cost allocation process in SFAS 141, which required the cost of an acquisition to be allocated to the individual assets acquired and liabilities assumed based on their estimated fair values. Acquisition-related costs will be expensed in the periods in which the costs are incurred or services are rendered. Costs to issue debt or equity securities shall be accounted for under other applicable GAAP. SFAS 141(R) applies prospectively to business combinations for which the acquisition date is on or after the first annual reporting period beginning on or after December 15, 2008. We expect SFAS 141(R) will not have an impact on our financial statements when effective, but the nature and magnitude of the specific effects will depend upon the nature, terms and size of any acquisitions we consummate after the effective date. If previously recorded income tax liabilities acquired in a business combination reverse subsequent to the adoption of SFAS 141(R), such reversals will affect expense including income tax expense in the period of reversal. Management is assessing the full impact SFAS 141(R) might have on future financial statements.

32


SFAS 160

In December 2007, the FASB issued SFAS 160. SFAS 160 amends ARB 51 and requires:

     Ownership interests in subsidiaries held by other parties other than the parent be clearly identified on the consolidated statement of financial position within equity, but separate from the parent’s equity;

     Consolidated net income attributable to the parent and to the non-controlling interest be clearly identified on the face of the consolidated statement of income;

     Changes in a parent’s ownership interest while the parent retains controlling financial interest be accounted for consistently as equity transactions;

     When a subsidiary is deconsolidated, any retained non-controlling equity investment in the former subsidiary be initially measured at fair value; and

     Sufficient disclosures that clearly identify and distinguish between the interests of the parent and the interests of the non-controlling owners.

SFAS 160 is effective for fiscal years beginning after December 15, 2008 and interim periods within those fiscal years. Management does not expect the adoption of SFAS 160 to have a significant effect on the Company’s financial statements.

SFAS 161

In March 2008, the FASB issued SFAS 161, which requires enhanced disclosures about how derivative and hedging activities affect an entity’s financial position, financial performance and cash flows. This Statement is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. Management does not expect the adoption of SFAS 161 to have a significant effect on the Company’s financial statements.

During December 2008 the FASB issued FSP FAS 132(R)-1, “Employers Disclosures about Postretirement Benefit Plan Assets.” The objectives of the disclosuresemployer's disclosure about plan assets in an employersfor a defined benefit pension or other postretirement planplans.  These disclosures are to provide users of financial statements with an understanding of:

     How investment allocation decisions are made, including the factors that are pertinent to an understanding of investment policies and strategies;

     The major categories of plan assets;

     The input and valuation techniques used to measure the fair value of plan assets;

     The effect of fair value measurements using significant unobservable inputs (Level 3) on changes in plan assets for the period; and

     Significant concentrations of risk within plan assets.

FSP FAS 132(R)-1 is effective for fiscal years ending after December 15, 2009.  Management doesSee Note 9 for additional information.


Recently Issued Accounting Standards

Consolidation of Variable Interest Entities, ASC 810-10-15

In June 2009, the FASB issued a revision regarding consolidations.  The revised accounting guidance requires a company to consider whether an entity that is insufficiently capitalized or is not expectcontrolled through voting should be consolidated.  It will require additional disclosures about the involvement with variable interest entities and any significant changes in risk exposure due to that involvement.  This standard is effective for annual periods that begin after November 15, 2009.  We are currently assessing the impact that the adoption of FSP FAS 132(R)-1this standard will have on our financial condition, results of operations, and cash flows.

Fair Value Measurements, ASC 820

In January 2010, the FASB issued guidance related to haveimproving disclosures about fair value measurements.  The guidance requires separate disclosures of the amounts of transfers in and out of Level 1 and Level 2 fair value measurements and a description of the reason for such transfers.  In the reconciliation for Level 3, fair value measurements using significant effectunobservable inputs, information about purchases, sales, issuances and settlements shall be presented separately.  These disclosures are required for interim and annual reporting periods and were effective for the Company on January 1, 2010, except for the Company’sdisclosures related to the purchases, sales, issuances and settlements in the roll forward activity of Level 3 fair value measurements, which are effective on January 1, 2011.  The guidance will require additional disclosures, but will not impact our financial statements.

EMPLOYEE BENEFIT PLANS

SFAS 158

The application


Funded Status of SFAS 158 requires recognition of theBenefit Plans

The funded status of postretirement benefit plans is required to be recognized in the statement of financial position.  The funded status for pension plans is measured as the difference between the projected benefit obligation and the fair value of plan assets.  The funded status for all other benefit plans is measured as the difference between the accumulated benefit obligation and the fair value of plan assets.  A liability is recorded for an amount by which the benefit obligation exceeds the fair value of plan assets or an asset is recorded for any amount by which the fair value of plan assets exceeds the benefit obligation.

Prior to the December 31, 2006 effective date of SFAS 158, liabilities recorded


We apply accounting standards for postretirement benefit plans were reduced by any unrecognized net periodic benefit cost. Upon adoption of SFAS 158, the unrecognized net periodic benefit cost, previously recorded as an offset to the liability for benefit obligations, was reclassified within AOCI, net of tax. The Company applied the guidance under SFAS 71,regulated operations, and accordingly, the unrecognized net periodic benefit cost that would have been reclassified to AOCIAccumulated other comprehensive income (loss) was alternatively recorded as a regulatory asset or regulatory liability, net of tax.

SFAS 158 required that the


The measurement date of plans should be the date of the Company’sour year-end balance sheet.  The CompanyWe had used a September 30 measurement date.  During 2008, the Companywe changed the measurement date to December 31.  Therefore, $0.2 million, net of tax, was recognized as an adjustment to retained earnings. The amortization of prior service costs for October 1, 2007 to December 31, 2007 was less than $0.1 million, net of tax, and the service cost, interest cost and expected return on plan assets for October 1, 2007 to December 31, 2007 was $0.2 million, net of tax.


Defined Benefit Pension Plan

The Company has


We have a noncontributory defined benefit pension plan (Plan) covering the employees of the Company who meet certain eligibility requirements.  The benefits are based on years of service and compensation levels during the highest five consecutive years of the last ten years of service.  The Company’sOur funding policy is in accordance with the federal government’sgovernment's funding requirements.  The Plan’sPlan's assets are held in trust and consist primarily of equity and fixed income investments.  The Company usesWe use a December 31 measurement date for the Plan.

41



In July 2009, the Board of Directors approved a freeze to our Defined Benefit Pension Plan (with the exception of bargaining unit participants).  The Plan’sfreeze is effective January 1, 2010 and eliminates new non-bargaining unit employees from participation in the plan, and freezes the benefits of current non-bargaining unit participants except for the following group:  those non-bargaining participants who are both 1) are age 45 or older as of December 31, 2009 and have 10 years or more of credited service as of January 1, 2010; and 2) elect to continue to accrue additional benefits under the pension plan and consequently forego the additional age- and points-based employer contribution under our 401(k) retirement savings plan.  Plan assets and obligations were revalued July 31, 2009 in conjunction with the freeze, and we recognized a pre-tax curtailment expense of approximately $0.2 million in the third quarter of 2009.


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 adjusted long-term historical returns for the asset class, with adjustments if itclass.  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% for the 20082009 and 20072008 plan years.  For determining the expected long-term rate of return for equity assets, the Companywe reviewed interest rate trends and annual 20-, 30-, 40-, and 50-year returns on the S&P 500 Index, which were, at December 31, 2008, 8.4%2009, 8.1%, 11.0%11.1%, 9.0%9.7% and 9.2%9.3%, respectively.  Fund management fees were estimated to be 0.18% for S&P 500 Index assets and 0.45% for other assets.  The expected long-term rate of return on fixed income investments was 6.0%; the return was based upon historical returns on 10-year treasury bonds of 7.1%6.9% from 1962 to 2007,2009, and adjusted for recent declines in interest rates.  The expected long-term rate of return on cash investments was estimated to be 4.0%; expected cash returns were estimated to be 2.0% below long-term returns on intermediate-term bonds.

The Investment Policy for the Pension Plans is to seek to achieve the following long-term objectives:  1) a resultrate of return in excess of the severe decline in equity values in the fourth quarter of 2008 and in light of the improved relative value of fixed income investment opportunities, we are undergoing a review to consider a revision of the pension plan investment allocations.

The revision is expected to result in a higher fixed income allocation. Until the investment allocation review is complete and implemented, we have suspended our practice of rebalancing the portfolioannualized inflation rate based on a quarterly basis. This has resulted in an investment allocation of 68% equities and 32% fixed income/cash at December 31, 2008.

The Plan’s investment policy includes the investment objective that the achieved long-term ratesfive-year moving average; 2) a rate of return meetthat meets or exceedexceeds the assumed actuarial rate.rate of return that meets or exceeds the assumed actuarial rate of return as stated in the Plan’s actuarial report; 3) a rate of  return on investments, net of expenses, that is equal to or exceeds various benchmark rates on a moving three-year average, and 4) maintenance of sufficient income and liquidity to pay monthly retirement benefits.  The policy strategy seeks to prudently invest in a diversified portfolio of predominately equity and fixed income assets. The policy provides that the Plan will maintain a passive core United States Stock portfolio based on a broad market index. Complementing this core will be investments in United States 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.

Supplemental NonqualifiedNon-qualified Defined Benefit Retirement Plans

The Company has


We have various supplemental retirement plans for key executives of the Company.executives.  The Plans are nonqualifiednon-qualified defined benefit plans.  The Company usesWe use a December 31 measurement date for the Plans.

  Effective January 1, 2010, we eliminated a non-qualified pension plan in which some of our officers participated due to the partial freeze of our qualified pension plans.  We also amended the NQDC, which was adopted in 1999.  The NQDC is a non-qualified deferred compensation plan that provides executives with an opportunity to elect to defer compensation and receive benefits without reference to the limitations on contributions in the Plan or those imposed by the IRS.  The amended NQDC provides for non-elective non-qualified restoration benefits to certain officers who are not eligible to continue accruing benefits under the Defined Benefit Pension Plans and associated non-qualified pension restoration plans.  All contributions to the non-qualified plans are subject to a graded vesting schedule of 20% per year over five years with vesting credit beginning with service in the Plan on and after January 1, 2010.


Plan Assets


The Plan has no assets.  The Company fundsWe fund on a cash basis as benefits are paid.


Estimated Cash Flows


The estimated employer contribution is expected to be $0.1 million in 2009.2010.  Contributions are expected to be made in the form of benefit payments.


Non-pension Defined Benefit Postretirement Plan


Employees who are participants in the Company’sour Postretirement Healthcare Plan and who retire from the Company on or after attaining age 55 after completing at least five years of service to the Company are entitled to postretirement healthcare benefits.  These benefits are subject to premiums, deductibles, co-payment provisions and other limitations.  The CompanyWe may amend or change the Plan periodically.  The Company isWe are not pre-funding itsour retiree medical plan.  The Company usesWe use a December 31measurement date for the Plan.  In July 2009, the Board of Directors approved a freeze to the Plan which changed the structure of the Plan for non-union employees to a Retiree Medical Savings Account structure and expanded eligibility of Plan participants, effective January 1, 2010.


It has been determined that the Plan’sPlan's post-65 retiree prescription drug plans are actuarially equivalent and qualify for the Medicare Part D subsidy.  The effect of the Medicare Part D subsidy on the accumulated postretirement benefit obligation for the fiscal year ending December 31, 2008,2009, was an actuarial gain of approximately $1.0$0.9 million.  The effect on 2009 net periodic postretirement benefit cost will bewas a decrease of approximately $0.1 million.

Fair Value Measurements

Accounting standards for fair value measurements provide a single definition of fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and also requires disclosures and establishes a fair value hierarchy that prioritizes the inputs used to measure fair value.  The fair value hierarchy ranks the quality and reliability of the information used to determine fair values giving the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements).  The pension plan is able to classify fair value balances based on the observability of inputs.

Financial assets and liabilities carried at fair value are classified and disclosed in one of the following three categories:

Level 1 – Unadjusted quoted prices available in active markets that are accessible at the measurement date for identical unrestricted assets or liabilities.

Level 2 – Pricing inputs include quoted prices for identical or similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 - Pricing inputs include significant inputs that are generally less observable from objective sources.

As required by accounting standards for fair value measurements, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.  Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect their placement within the fair value hierarchy levels.  The following tables set forth, by level within the fair value hierarchy, the assets that were accounted for at fair value on a recurring basis as of December 31, 2009 and 2008 (in thousands):

_____________________________

*

The expected rate of return on plan assets remained at 8.50%changed to 8.00% for the calculation of the 20092010 net periodic pension cost.


The healthcare cost trend rate assumption for 2009 fiscal year benefit obligation determination and 2010 fiscal year expense is a 10% increase for 2009 grading down until a 4.5% ultimate trend rate is reached in fiscal year 2027.  The healthcare cost trend rate assumption for the 2008 fiscal year benefit obligation determination and 2009 fiscal year expense iswas a 9% increase for 2009 grading down 1% per year until a 5% ultimate trend rate is reached in fiscal year 2013. The healthcare cost trend rate assumption for the 2008 fiscal year benefit obligation determination and 2008 fiscal year expense was a 10% increase for 2008 grading down 1% per year until a 5% ultimate trend rate is reached in fiscal year 2013.

46



The healthcare cost trend rate assumption has a significant effect on the amounts reported.  A 1% increase in the healthcare cost trend assumption would increase the service and interest cost $0.1 million or 21%22% and the accumulated periodic postretirement benefit obligation $1.3 million or 18%14%.  A 1% decrease would reduce the service and interest cost by $0.1 million or 16%17% and the accumulated periodic postretirement benefit obligation $1.0 million or 14%11%.
