Item 8.01  Other Items.

On January 20, 2011, representatives of Idaho Power Company (“Idaho Power”) will participate in the Integrated Resource Plan Advisory Council meeting in Boise, Idaho, which is open to the public.  At that meeting, Idaho Power will, among other things, provide an update on estimated costs for its Boardman to Hemingway transmission line project, a proposed 500-kV transmission project between a station near Boardman, Oregon and a station near Boise, Idaho. The updated cost estimate was prepared in connection with an order of the Oregon Public Utility Commission acknowledging Idaho Power’s 2009 Integrated Resources Plan, which order requested that Idaho Power update its project analysis and estimate of construction costs for the transmission line.  Idaho Power retained an independent engineering consulting firm to develop the updated cost estimate.  Based on the analysis, Idaho Power currently estimates that the total cost of the project will be approximately $820 million, including allowance for funds used during construction.  This cost estimate excludes the impacts of inflation and price changes of materials and labor resources that occur following the date of the estimate.  Idaho Power is discussing joint development of the project with third parties and continues to expect that its share of the project will be 30 to 50 percent.  While Idaho Power’s forecast of load requirements indicates that immediate system reliability benefits could be realized by accelerating construction of the transmission line for an earlier in-service date, Idaho Power is currently targeting a completion date of mid-2016 for the project, subject to siting, permitting, regulatory approvals, and other conditions. Idaho Power’s earlier, initial estimate of the total cost of the project was approximately $600 million, with a targeted completion date of 2015.

Forward-Looking Statements

Certain statements contained in the presentation slides, including statements with respect to future earnings, ongoing operations, and financial condition, are forward-looking statements within the meaning of federal securities laws and are intended to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. Any statements that express, or involve discussions as to expectations, beliefs, plans, objectives, assumptions, or future events or performance, often, but not always, through the use of words or phrases such as “expects,” “targeting,” and “estimates” or similar expressions, are not statements of historical facts and may be forward-looking.  Although IDACORP and Idaho Power Company believe that the expectations and assumptions reflected in these forward-looking statements are reasonable, these statements involve a number of risks and uncertainties, and actual results may differ materially from the results discussed in the statements.  Factors that could cause actual results to differ materially from the forward-looking statements include the following: (a) the effect of regulatory decisions by the Idaho Public Utilities Commission, the Oregon Public Utility Commission, and the Federal Energy Regulatory Commission affecting Idaho Power Company’s ability to recover costs and/or earn a reasonable rate of return, including, but not limited to, the recovery or disallowance of costs that have been deferred, financings, allowed rates of return, electricity pricing and price structures, acquisition and disposal of assets and facilities, and current or prospective wholesale and retail competition; (b) changes in and compliance with state and federal laws, policies, and regulations, including new interpretations by regulatory and oversight bodies, which include the Federal Energy Regulatory Commission, the North American Electric Reliability Corporation, the Western Electricity Coordinating Council, the Idaho Public Utilities Commission, the Oregon Public Utility Commission, and the Department of Energy of existing policies and regulations that affect the cost of compliance, investigations and audits, penalties, and costs of remediation that may or may not be recoverable through rates; (c) changes in tax laws or related regulations or new interpretations of applicable law by the Internal Revenue Service or state and local taxing jurisdictions, and the availability and use by IDACORP, Inc. or Idaho Power Company of any tax credits; (d) litigation and regulatory proceedings, including those resulting from the energy situation in the western United States and the Snake River Basin water rights adjudication, and penalties, settlements, or awards that influence business and profitability; (e) changes in and costs of compliance with laws, regulations, and policies relating to the environment, natural resources, and endangered species and the adoption of laws and regulations addressing greenhouse gas emissions, global climate change, and energy policies, particularly with respect to coal-fired generation facilities, intended to mitigate carbon dioxide, mercury, and other emissions; (f) increases in capital expenditures and potential reductions in generation capacity as a result of regulatory conditions that may be imposed on hydroelectric power generating plant license renewals, or the non-renewal of such licenses; (g) global climate change and regional weather variations affecting customer demand and hydroelectric generation; (h) over-appropriation of surface and groundwater in the Snake River Basin, including proposals for use of water in the Snake River Basin for aquifer recharge, resulting in reduced generation at hydroelectric facilities; (i) construction of power generation, transmission, and distribution facilities, including an inability to obtain required governmental

permits and approvals, rights-of-way, and siting, and risks related to contracting, construction, and start-up; (j) delays and cost increases in connection with the construction or modification of generating facilities and other capital projects, which could result in the disallowance of recovery of certain costs pursuant to the rate determination process; (k) operation of power generating facilities, including performance below expected levels, breakdown or failure of equipment, forced outages, availability of electrical transmission capacity, and the availability of water for hydroelectric power generation, natural gas, coal, and diesel for power generation at thermal plants, and wind conditions for wind power generation, and the delivery infrastructures associated with those power generation facilities; (l) changes in operating expenses and capital expenditures, including costs and availability of materials, fuel, and commodities, and their impact on Idaho Power Company’s ability to meet required loads and on the wholesale energy market in the western United States; (m) blackouts or other disruptions of Idaho Power Company’s transmission system or the western interconnected transmission system; (n) population growth rates and changes in residential, commercial, and industrial growth and demographic patterns within Idaho Power Company’s service area; (o) the continuing effects of weak economies in the states of Idaho and Oregon and in the United States, including decreased demand for electricity and reduced revenue from sales of excess energy during periods of low wholesale market prices, impaired financial soundness of vendors and service providers, and elevated levels of uncollectible customer accounts; (p) market prices and demand for energy, including structural market changes; (q) reductions in credit ratings, which could adversely impact access to capital markets and would require the posting of additional collateral to counterparties pursuant to existing power purchase and other arrangements; (r) increases in uncollectible customer receivables, and the effectiveness of Idaho Power Company’s risk management policies concerning the creditworthiness of third parties; (s) results of financing efforts, including the ability to obtain financing or refinance existing debt when necessary or on favorable terms, which can be affected by factors such as credit ratings, volatility in the financial markets, and other economic conditions; (t) increases in the costs associated with Idaho Power Company’s energy commodity and other derivative instruments, and potential higher costs of hedging activities due to governmental regulation; (u) performance of the stock market, interest rates, credit spreads, inflation, and other financial market conditions, as well as changes in government regulations, which affect, among other things, the cost of capital and the ability to access the capital markets, indebtedness obligations, the amount and timing of required contributions to pension plans, and the reported costs of providing pension and other postretirement benefits; (v) increases in health care costs and the resulting effect on medical benefits paid for employees; (w) increasing costs of insurance, changes in coverage terms, and the ability to obtain insurance on reasonable terms or at all; (x) the occurrence of events that affect homeland security, and acts of war or terrorism; (y) weather and other natural phenomena such as earthquakes, floods, droughts, lightning, wind, and fire, which, in addition to affecting customer demand for power, could significantly affect the ability and cost to procure adequate supplies of fuel or power to serve customers, and could increase the costs to prevent destruction of and maintain Idaho Power Company’s generating facilities, transmission and distribution systems, and other infrastructure; (z) adoption of or changes in accounting policies, principles, or estimates; (aa) unionization, or the attempt to unionize, all or part of the companies’ workforce, and the resulting effects on production, profitability, and operations; and (bb) new accounting or Securities and Exchange Commission or New York Stock Exchange requirements, or new interpretations or application of existing requirements.  Any such forward-looking statements should be considered in light of these factors and others noted in the companies’ Annual Report on Form 10-K for the year ended December 31, 2009, subsequent Quarterly Reports on Form 10-Q, and other reports on file with the Securities and Exchange Commission.  Any forward-looking statement speaks only as of the date on which such statement is made.  New factors emerge from time to time and it is not possible for management to predict all such factors, nor can it assess the impact of any such factor on the business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement.
