Properties, in its own words

Idaho Power's properties consist of the physical assets necessary to support its utility operations, which include generation, battery storage, transmission, and distribution facilities. In addition to these physical assets, Idaho Power has rights-of-way and water rights that enable it to use its facilities. Idaho Power’s system is composed of 17 hydropower generating plants located in southern Idaho and eastern Oregon, three natural gas-fired plants in southern Idaho, and interests in a coal-fired and natural gas-fired steam generating plant located in Wyoming and a gas-fired steam generating plant in Nevada. As of December 31, 2025, the system also includes approximately 4,730 pole miles of high-voltage transmission lines, 23 step-up transmission substations located at power plants, 21 transmission substations, 12 switching stations, 31 mixed-use transmission and distribution substations, 188 energized distribution substations (excluding mobile substations and dispatch centers), approximately 30,020 linear miles of distribution lines, and a capacity of 1,228 MWh of battery storage, comprised of 9 facilities, located in southern Idaho and eastern Oregon. As part of the Oregon Sale, Idaho Power expects to sell to OTEC substantially all of its Oregon distribution lines and several substations and certain other assets located in Oregon.

IDACORP's and Idaho Power's headquarters are located in Boise, Idaho. The corporate headquarters campus consists of approximately 305,741 square feet of owned office space. Excluding Idaho Power's power generation facilities and substations, Idaho Power owns an additional 1,218,813 square feet of office, warehouse, and industrial space to support its operations in Idaho and Oregon.

The rest of Item 2

Idaho Power owns all of its interests in principal plants and other important units of real property, except for portions of certain projects licensed under the FPA and reservoirs and other easements. Substantially all of Idaho Power’s property is subject to the lien of its Mortgage and Deed of Trust and the provisions of its project licenses. Idaho Power’s property is subject to minor defects common to properties of such size and character that it believes do not materially impair the value to, or the use by, Idaho Power of such properties. Idaho Power considers its properties to be well-maintained and in good operating condition.

Through IERCo, Idaho Power owns a one-third interest in BCC and coal leases near the Jim Bridger plant in Wyoming from which coal is mined and supplied to generating units 3 and 4 of the plant. Ida-West holds 50-percent interests in nine hydropower plants that have a total nameplate capacity of 44 MW. These plants are located in Idaho and California.

Risk factors and legal proceedings

The risks Idacorp names in Item 1A of its 10-K filed Feb 19, 2026: 30 risks under these headings, as written.17

  • Utility-Specific Regulatory Risks
  • State or federal regulators may not approve customer rates that provide timely or sufficient recovery of Idaho Power's costs or allow Idaho Power to earn a reasonable rate of return, which could adversely affect IDACORP's and Idaho Power's financial condition and results of operations.
  • Idaho Power's regulatory cost recovery mechanisms may not function as intended and are subject to change or elimination, which may adversely affect IDACORP's and Idaho Power's financial condition and results of operations.
  • Operational Risks
  • Changes in customer growth and customer usage may negatively affect IDACORP's and Idaho Power's business, financial condition, and results of operations.
  • Changes in weather conditions, severe weather, and the impacts of climate change can affect IDACORP's and Idaho Power's operating results and cause them to fluctuate seasonally.
  • Liability from fires could adversely impact IDACORP's and Idaho Power's business, financial condition, and results of operations, and Idaho Power's WMP and other protocols may not prevent such liability.
  • Acts or threats of terrorism, acts of war, social unrest, cyber or physical security attacks, and other malicious acts of individuals or groups seeking to disrupt Idaho Power's operations or the electric power grid or compromise data could adversely impact IDACORP's and Idaho Power's business, financial condition, and results of operations.
  • Changes in capital expenditures for infrastructure and the risks associated with permitting and construction of utility infrastructure can significantly affect IDACORP's and Idaho Power's financial condition and results of operations.
  • Factors contributing to lower hydropower generation can increase costs and negatively impact IDACORP's and Idaho Power's financial condition and results of operations.
  • Idaho Power’s use of coal and natural gas to fuel power generation facilities exposes it to commodity availability and price risk, which can adversely affect IDACORP's and Idaho Power's results of operations and financial condition.
  • Idaho Power’s power supply, transmission, and distribution facilities are subject to numerous operational risks unique to it and its industry, including circumstances causing power outages, injuries and property damage, loss of life, and fires.
The other 20 risks
  • IDACORP's and Idaho Power's activities are concentrated in one industry and in one region, which exposes it to risks from lack of diversification, regional economic conditions, and regional legislation and regulation.
  • The impacts of turnover in a workforce with specialized utility-specific functions and the inability to hire qualified third-party vendors could increase costs and adversely affect IDACORP's and Idaho Power's financial condition and results of operations.
  • Co-owners of Idaho Power’s generation and transmission assets may have unaligned goals and positions due to the effects of legislation, regulations, capital requirements, load growth amounts, changes in its industry, or other factors, which could adversely impact Idaho Power’s ability to construct and operate those facilities in a manner most suitable to Idaho Power.
  • Legal and Compliance Risks
  • Changes in legislation, regulation, and government policy may have a material adverse effect on IDACORP’s and Idaho Power’s business.
  • Changes in U.S. trade policy and the impact of tariffs could have an adverse effect on Idaho Power's business and results of operations.
  • IDACORP's and Idaho Power’s businesses are subject to an extensive set of environmental laws, rules, and regulations, which could impact their operations and costs of operations, potentially rendering some generating units uneconomical to maintain or operate, and could increase the costs and alter the timing of major projects.
  • Obligations imposed in connection with hydropower license renewals and permitting may require large capital expenditures, increase operating costs, reduce hydropower generation, and negatively affect IDACORP's or Idaho Power's results of operations and financial condition.
  • Idaho Power could be subject to penalties, reputational harm, and operational changes if it violates mandatory reliability and security requirements, which could adversely impact IDACORP's and Idaho Power's results of operations and financial condition.
  • IDACORP and Idaho Power are subject to costs and other effects of legal and regulatory proceedings, disputes, and claims.
  • Changes in accounting standards or rules may impact IDACORP's and Idaho Power's financial results and disclosures.
  • Financial and Investment Risks
  • Volatility or disruptions in the financial markets, failure of IDACORP or Idaho Power to satisfy conditions necessary for obtaining loans or issuing debt securities, and denial of regulatory authority to issue debt or equity securities, may negatively
  • affect IDACORP’s and Idaho Power’s ability to access capital and/or increase their cost of borrowing and ability to execute on their strategic plans.
  • A downgrade in IDACORP’s and Idaho Power’s credit ratings could affect the companies’ ability to access capital, increase their cost of borrowing, and require the companies to post collateral with transaction counterparties.
  • Stakeholder actions and regulatory activity related to sustainability matters, particularly global climate change and reducing GHG emissions, could negatively impact IDACORP and Idaho Power.
  • Idaho Power’s energy risk management policy and programs relating to economically hedging commodity exposures and credit risk may not always perform as intended, and as a result, IDACORP and Idaho Power may suffer losses.
  • The performance of pension and postretirement benefit plan investments, increasing health care costs, and other factors impacting plan costs and funding obligations could adversely affect IDACORP's and Idaho Power's financial condition and results of operations - primarily cash flows and liquidity.
  • If the assumptions underlying coal mine reclamation at BCC and related forecast trust fund growth are materially inaccurate, Idaho Power’s costs could be greater than anticipated or be incurred sooner than anticipated.
  • As a holding company, IDACORP does not have its own operating income and must rely on the cash flows from its subsidiaries to pay dividends and make debt payments.
  • The market price of IDACORP's common stock may be volatile.
  • IDACORP's charter and bylaws and various legal and regulatory factors could delay or prevent a change in control that shareholders may favor.

Legal proceedings

Refer to Note 11 – “Contingencies” to the consolidated financial statements included in this report. SEC regulations require IDACORP and Idaho Power to disclose certain information about proceedings arising under federal, state or local environmental provisions if the companies reasonably believe that such proceedings may result in monetary sanctions above a stated threshold. Pursuant to the SEC regulations, the companies use a threshold of $1 million or more for purposes of determining whether disclosure of any such proceedings is required.
