IDACORP INC 10-K

ITEM 1. BUSINESS OVERVIEW Background IDACORP is a holding company incorporated in 1998 under the laws of the state of Idaho. Its principal operating subsidiary is Idaho Power. IDACORP is subject to the provisions of the Public Utility Holding Company Act of 2005, which provides the FERC and state utility regulatory commissions with access to books and records and imposes record retention and reporting requirements on IDACORP. Idaho Power was incorporated under the laws of the state of Idaho in 1989 as the successor to a Maine corporation that was organized in 1915 and began operations in 1916. Idaho Power is an electric utility engaged in the generation, transmission, distribution, sale, and purchase of electric energy and capacity and is regulated by the state regulatory commissions of Idaho and Oregon and by the FERC. Idaho Power is the parent of IERCo, a joint-owner of BCC, which mines and supplies coal to the Jim Bridger plant owned in part by Idaho Power. Idaho Power's utility operations constitute nearly all of IDACORP's current business operations. IDACORP’s other notable subsidiaries include IFS, an investor in affordable housing and other real estate tax credit investments, and Ida-West, an operator of small hydropower generation projects that satisfy the requirements of the PURPA. IDACORP’s and Idaho Power’s principal executive offices are located at 1221 W. Idaho Street, Boise, Idaho 83702, and the telephone number is (208) 388-2200.

UTILITY OPERATIONS Background Idaho Power provided electric utility service to approximately 633,000 retail customers in southern Idaho and eastern Oregon as of December 31, 2023. Approximately 532,000 of these customers are residential. Idaho Power’s principal commercial and industrial customers are involved in food processing, electronics and general manufacturing, agriculture, health care, government, and education. Idaho Power also provides irrigation customers with electric utility service to operate irrigation pumps during the agricultural growing season. Idaho Power holds franchises, typically in the form of right-of-way arrangements, in 72 cities in Idaho and 7 cities in Oregon and holds certificates from the respective public utility regulatory authorities to serve all or a portion of 25 counties in Idaho and 3 counties in Oregon. Idaho Power's service area is shaded in the illustration on the following page and covers approximately 24,000 square miles with an estimated population of 1.4 million. 7 Table of Contents Idaho Power is under the jurisdiction (as to rates, service, accounting, and other general matters of utility operation) of the IPUC, the OPUC, and the FERC. The IPUC and OPUC determine the rates that Idaho Power is authorized to charge to its retail customers. Idaho Power is also under the regulatory jurisdiction of the IPUC, the OPUC, and the WPSC as to the issuance of debt and equity securities. As a public utility under the FPA, Idaho Power has authority to charge market-based rates for wholesale energy sales under its FERC tariff and to provide transmission services under its OATT. Additionally, the FERC has jurisdiction over Idaho Power's sales of transmission capacity and wholesale electricity, hydropower project relicensing, and system reliability and security, among other items. Regulatory Accounting Idaho Power meets the requirements under accounting principles generally accepted in the United States of America to prepare its financial statements applying the specialized rules to account for the effects of cost-based rate regulation, with the impacts of rate regulation reflected in its financial statements. Accounting for the economics of rate regulation impacts multiple financial statement line items and disclosures. These principles sometimes result in Idaho Power recording expenses and revenues in a different period than when an unregulated enterprise would record such expenses and revenues. In these instances, the amounts are deferred or accrued as regulatory assets or regulatory liabilities on the balance sheet and recorded on the income statement when recovered or returned in rates or when otherwise directed to begin amortization by a regulator. Additionally, regulators can impose regulatory liabilities upon a regulated company for amounts previously collected from customers that are expected to be refunded. Idaho Power records regulatory assets or liabilities if it expects the amounts will be reflected in future customer rates, based on regulatory orders or other available evidence. Consistent with orders and directives of the IPUC, unless contrary to applicable income tax guidance, Idaho Power does not provide deferred income tax expense or benefit for certain income tax temporary differences and instead recognizes the tax impact currently (commonly referred to as flow-through accounting) for rate making and financial reporting. Therefore, Idaho Power's effective income tax rate is impacted as these differences arise and reverse. Idaho Power recognizes such adjustments as regulatory assets or liabilities if it is probable that the amounts will be recovered from or returned to customers in future rates. 8 Table of Contents Business Strategy IDACORP is committed to its focus on competitive total returns and generating long-term value for shareholders. IDACORP’s business strategy emphasizes Idaho Power as its core business, as Idaho Power's regulated utility operations are the primary driver of IDACORP's operating results. IDACORP’s strategy is focused on four areas: keeping employees safe and engaged, growing financial strength, improving Idaho Power's core business, and enhancing Idaho Power’s brand. IDACORP's board of directors has reviewed and affirmed IDACORP’s long-term strategy. In executing on these four strategic cornerstones, IDACORP seeks to balance the interests of shareowners, Idaho Power customers, employees, and other stakeholders. Idaho Power is committed to working for strong, sustainable financial results by continuing to safely provide reliable, affordable, clean energy to its customers from diversified generation resources. Rates and Revenues Idaho Power generates revenue primarily through the sale of electricity to retail and wholesale customers and the provision of transmission service. The prices that the IPUC, the OPUC, and the FERC authorize Idaho Power to charge for electric power and services are critical factors in determining IDACORP's and Idaho Power's results of operations and financial condition. In addition to the discussion below, more information on Idaho Power's regulatory framework and rate regulation can be found in the “Regulatory Matters” section of Part II, Item 7 – MD&A and Note 3 – “Regulatory Matters” to the consolidated financial statements included in this report. Retail Rates : Idaho Power's rates for retail electric services are generally determined on a “cost of service” basis. Rates are designed to provide an opportunity for Idaho Power to earn a reasonable return on investment as authorized by regulators, after recovery of allowable operating expenses, including depreciation on capital investments. Idaho Power regularly evaluates the need to request changes in its retail electricity price structure through the use of general rate cases, power cost adjustment mechanisms in Idaho and Oregon, an FCA mechanism in Idaho, balancing accounts, and also uses tariff riders, and subject-specific filings to recover its costs of providing service and to earn a return on investment. Retail prices are generally determined through formal ratemaking proceedings that are conducted under established procedures and schedules before the issuance of a final order. Participants in these proceedings include Idaho Power, the staffs of the IPUC or OPUC, and other interested parties. The IPUC and OPUC are charged with ensuring that the prices and terms of service are fair, are non-discriminatory, and provide Idaho Power an opportunity to recover its prudently incurred or allowable costs and expenditures and earn a reasonable return on investment. The ability to request rate changes does not, however, ensure that Idaho Power will recover all of its costs or earn a specified rate of return, or that its costs will be recovered in advance of or at the same time when the costs are incurred. In addition to general rate case filings, ratemaking proceedings can involve charges or credits related to specific costs, programs, or activities, as well as the recovery or refund of amounts deferred or accrued under specific authorization from the IPUC or OPUC. Deferred amounts are generally collected from, and accrued amounts are generally refunded to, retail customers through the use of base rates or supplemental tariffs. Outside of base rates, three of the most significant mechanisms for recovery of costs are the power cost adjustment mechanisms, FCA mechanism, and energy efficiency riders. For more information on these mechanisms, see Note 3 – “Regulatory Matters” and Note 4 – “Revenues” to the consolidated financial statements included in this report. Retail Energy Sales: Weather, seasonal customer demand, energy efficiency, customer generation, customer growth, and economic conditions all impact the amount of electricity that Idaho Power sells as well as the costs it incurs to provide that electricity. Idaho Power's utility revenues are not earned, and associated expenses are not incurred, evenly during the year. Idaho Power’s retail energy sales typically peak during the summer irrigation and cooling season, with a lower peak during the winter heating season. Extreme temperatures increase sales to customers who use electricity for cooling and heating, and mild temperatures decrease sales. Availability of water and variations in temperatures and precipitation during the agricultural growing season impact electricity sales to customers who use electricity to operate irrigation pumps. Alternative methods of generation, including customer-owned solar and other forms of distributed generation, have the potential to decrease Idaho Power sales to customers. Also, development of new technologies and services to help energy consumers manage energy in new ways could continue to alter demand for Idaho Power's electric energy. Approximately 95 percent of Idaho Power’s retail revenue originates from customers located in Idaho, with the remainder originating from customers located in Oregon. Idaho Power’s operations, including information on energy sales, are discussed further in Part II, Item 7 - MD&A - "Results of Operations - Utility Operations.” 9 Table of Contents The table that follows presents Idaho Power’s revenues and sales volumes for the last three years, classified by customer type. Year Ended December 31, 2023 2022 2021 Retail revenues (thousands of dollars): Residential (includes $37,233, $22,595, and $34,835, respectively, related to the FCA) $ 684,649 $ 645,236 $ 583,061 Commercial (includes $1,338, $922, and $1,407, respectively, related to the FCA) 378,330 347,970 314,745 Industrial 244,538 217,368 195,214 Irrigation 173,929 170,964 168,664 Provision for sharing — — (569) Deferred revenue related to HCC relicensing AFUDC (1) (8,780) (8,780) (8,780) Total retail revenues 1,472,666 1,372,758 1,252,335 Wholesale energy sales 63,421 66,519 40,839 Transmission wheeling-related revenues 80,357 80,527 67,997 Energy efficiency program revenues 31,948 33,197 29,920 Other revenues 114,502 88,039 64,319 Total electric utility operating revenues $ 1,762,894 $ 1,641,040 $ 1,455,410 Energy sales (thousands of MWh): Residential 5,903 6,056 5,645 Commercial 4,269 4,306 4,164 Industrial 3,538 3,510 3,471 Irrigation 1,805 1,950 2,126 Total retail energy sales 15,515 15,822 15,406 Wholesale energy sales 840 427 600 Energy sales bundled with RECs 1,255 892 739 Total energy sales 17,610 17,141 16,745 (1) The IPUC allows Idaho Power to recover a portion of the AFUDC on construction work in progress related to the HCC relicensing process, even though the relicensing process is not yet complete and the costs have not been moved to electric plant in service. Idaho Power is collecting $8.8 million annually in the Idaho jurisdiction but is deferring revenue recognition of the amounts collected until the license is issued and the accumulated license costs approved for recovery are placed in service. Wholesale Markets : Idaho Power participates in the wholesale energy markets by purchasing power to help meet load demands and selling power that is in excess of load demands. Idaho Power's market activities are guided by an energy risk management program and frequently updated operating plans. These operating plans are impacted by factors such as customer demand for power, market prices, generating costs, transmission constraints, and availability of generating resources. Idaho Power's wholesale energy sales depend largely on the availability of generation resources above the amount necessary to serve customer loads as well as market power prices at the time when those resources are available. A reduction in either factor leads to lower wholesale energy sales. Idaho Power also provides energy transmission services through its OATT. The OATT rate is revised each year based primarily on financial and operational data Idaho Power files annually with the FERC in its Form 1. The FERC oversees mandatory transmission and network reliability standards, as well as power and transmission markets, including protection against market manipulation. These mandatory transmission and reliability standards were developed by the North American Electric Reliability Corporation and the Western Electricity Coordinating Council, which have responsibility for compliance and enforcement of transmission, reliability, and security standards. Competition: Idaho Power's electric utility business has historically been recognized as a natural monopoly. Idaho Power competes with fuel distribution companies, including natural gas providers, in serving the energy needs of customers for space heating, water heating, and appliances. Alternative methods of generation, including customer-owned solar and other forms of distributed generation, and energy efficiency measures, also have the potential to decrease Idaho Power sales to existing customers. 10 Table of Contents Idaho Power also participates in the wholesale energy markets and in the electricity transmission markets. Generally, these wholesale markets are regulated by the FERC, which requires electric utilities to transmit power to or for wholesale purchasers and sellers and make available transmission capacity, on a non-discriminatory basis, for the purpose of providing these services. In return for agreeing to provide service to all customers within a defined service area, electric utilities are typically provided with an exclusive right to provide service in that service area. However, certain prescribed areas within Idaho Power's service area, such as municipalities or Native American Tribal reservations, may elect not to take service from Idaho Power and instead operate as a municipal electric utility or otherwise as a separate entity. In such cases, the entity would be required to purchase or otherwise obtain rights to Idaho Power's distribution infrastructure within the municipal or other designated area. Idaho Power would have no responsibility for providing electric service to the municipal or separate entity, absent Idaho Power's voluntary agreement to provide that service. Power Supply Overview: Idaho Power primarily relies on company-owned hydropower, coal-fired, and gas-fired generation facilities and long-term power purchase agreements to supply the energy needed to serve customers and to make power sales into the wholesale markets. Market purchases and sales are used to supplement Idaho Power's generation and balance supply and demand throughout the year. Idaho Power’s generating plants and their capacities are listed in Part I, Item 2 - “Properties.” Various external and internal factors impact power supply costs, such as weather, load demand, economic conditions, fuel costs, and availability of generation resources. Idaho Power’s annual hydropower generation varies depending on water conditions in the Snake River Basin. Drought conditions and increased peak load demand cause a greater reliance on potentially more expensive energy sources to meet load requirements. Conversely, favorable hydropower generation conditions increase production at Idaho Power’s hydropower generating facilities and reduce the need for thermal generation and wholesale market purchased power. Weather also affects the generation of projects with which Idaho Power has contracts to purchase power. Economic conditions, weather, supply constraints, and governmental regulations can affect the market price of natural gas and coal, which impact fuel expense and market prices for purchased power. Idaho Power's power cost adjustment mechanisms mitigate in large part the earnings impacts to Idaho Power of volatile fuel and power costs. Idaho Power’s system is dual peaking, with the larger peak demand occurring in the summer. Idaho Power reached its highest all-time system peak demand of 3,751 MW on June 30, 2021. Idaho Power's highest all-time winter peak demand of 2,719 MW occurred on January 16, 2024. During these and other similar heavy load periods, Idaho Power’s system is fully committed to serve load and meet required operating reserves. The table that follows shows Idaho Power’s total power supply for the last three years. Power Supply Percent of Total Generation 2023 2022 2021 2023 2022 2021 (thousands of MWh) Hydropower plants 6,548 5,347 5,382 55 % 48 % 48 % Coal-fired plants 2,473 3,657 2,981 21 % 32 % 27 % Natural gas-fired plants 2,917 2,319 2,765 24 % 20 % 25 % Total system generation 11,938 11,323 11,128 Purchased power 7,027 7,178 6,823 Total power supply 18,965 18,501 17,951 Hydropower Generation : Idaho Power operates 17 hydropower projects located on the Snake River and its tributaries. Together, these hydropower facilities provide a total nameplate capacity of 1,818 MW and have averaged total annual generation of approximately 7.6 million MWh over the last 30 years. The amount of water available for hydropower generation depends on several factors—the amount of snowpack in the mountains upstream of Idaho Power’s hydropower facilities, upstream reservoir storage, springtime precipitation and temperatures, main river and tributary base flows, the condition of the Eastern Snake Plain Aquifer and its spring flow impact, summertime irrigation withdrawals and returns, and upstream reservoir regulation. Idaho Power actively participates in collaborative work groups focused on water management issues in the Snake River Basin, with the goal of preserving the long-term availability of water for use at Idaho Power’s hydropower projects on the Snake River. 11 Table of Contents In 2023, hydropower generation was 6.5 million MWh, an increase from the prior two years, due to above-normal snow accumulation throughout most of the Snake River basin. In 2022 and 2021, below-normal snow accumulation and drought conditions resulted in lower than average hydropower generation of 5.3 million and 5.4 million MWh, respectively. Idaho Power's 2024 estimate of annual generation from its hydropower facilities is between 5.5 million MWh and 7.5 million MWh. Idaho Power obtains licenses for its hydropower projects from the FERC, similar to other utilities that operate nonfederal hydropower projects on qualified waterways. The licensing process includes an extensive public review process and involves numerous natural resource and environmental agencies. The licenses last from 30 to 50 years depending on the size, complexity, and cost of the project. Idaho Power is actively pursuing the FERC relicensing of the HCC, its largest hydropower generation source, and American Falls, its second largest hydropower resource. Idaho Power also has Oregon licenses for the HCC under the Oregon Hydroelectric Act. For further information on relicensing activities, see Part II, Item 7 – MD&A – "Regulatory Matters – Relicensing of Hydropower Projects.” Idaho Power is subject to the provisions of the FPA as a “public utility” and as a “licensee” by virtue of its hydropower operations. As a licensee under Part I of the FPA, Idaho Power and its licensed hydropower projects are subject to conditions described in the FPA and related FERC regulations. These conditions and regulations include, among other items, provisions relating to condemnation of a project upon payment of just compensation, amortization of project investment from excess project earnings, and possible takeover of a project after expiration of its license upon payment of net investment and severance damages. Coal-Fired Generation : Idaho Power co-owns the following coal-fired power plants: • Jim Bridger, located in Wyoming, in which Idaho Power has a one-third interest; and • North Valmy, located in Nevada, in which Idaho Power has a 50 percent interest. PacifiCorp is the operator of the Jim Bridger plant. BCC supplies coal to the Jim Bridger plant. IERCo, a wholly-owned subsidiary of Idaho Power, owns a one-third interest in BCC and PacifiCorp owns a two-third interest in BCC and is the operator of the Bridger Coal Mine. The mine operates under a long-term sales agreement that provides for delivery of coal through 2024. BCC has reserves to provide coal deliveries through the current term of the agreement, as well as reserves available to allow for an extension of the term agreement. Idaho Power has an established process approved by the IPUC for recovery of non-fuel, coal-related costs related to Idaho Power’s plan to end its participation in coal-fired operations at the Jim Bridger plant. The conversion from coal to natural gas of two generating units at the Jim Bridger plant is in progress and is expected to be completed in the spring of 2024. NV Energy is the operator of the North Valmy plant. Idaho Power expects to meet 2024 and future fuel requirements through existing inventory and new or existing coal supply contracts. Idaho Power has an established process approved by the IPUC and OPUC for recovery of non-fuel costs related to Idaho Power’s plan to end its participation in coal-fired operations at the North Valmy plant. Idaho Power ended its participation in coal-fired operations at unit 1 of the North Valmy plant in December 2019, as planned. Idaho Power's 2023 IRP identified a preferred resource portfolio and action plan that includes the conversion from coal to natural gas of two units at the Jim Bridger plant in 2024, the two units at the North Valmy plant in 2026, and the remaining two units at the Jim Bridger plant in 2030. For more information on the 2023 IRP, refer to "Resource Planning" in this Item 1 – "Business." Idaho Power expects to seek approval from the IPUC and OPUC for any necessary adjustments to plant retirement dates to align with its current resource plan. Natural Gas-fired Generation : Idaho Power owns and operates the Langley Gulch natural gas-fired combined-cycle combustion turbine power plant and the Danskin and Bennett Mountain natural gas-fired simple-cycle combustion turbine power plants. All three plants are located in Idaho. As noted previously, in the spring of 2024, the conversion of two units at the Jim Bridger plant from coal to natural gas-fired steam turbines is expected to be completed. Idaho Power operates the Langley Gulch plant as a baseload unit and the Danskin and Bennett Mountain plants to serve load and meet peak supply needs. The natural-gas-fired units at the Jim Bridger plant will operate to serve load and meet peak supply needs. The plants are also used to take advantage of wholesale market opportunities. Natural gas for all facilities is purchased based on system requirements and dispatch efficiency. The natural gas is transported through Idaho Power's long-term gas transportation service agreements with the Williams-Northwest Pipeline for 55,584 MMBtu per day and Williams-Mt. West Overthrust Pipeline for 89,000 MMBtu per day. These transportation agreements vary in contract length but generally contain the right for Idaho Power to extend the term. In addition to the long-term gas transportation service agreements, Idaho 12 Table of Contents Power has entered into long-term storage service agreements with Northwest Pipeline and Spire Inc. for 131,453 MMBtu and 1 billion cubic feet, respectively, of total storage capacity. The firm storage contract with Northwest Pipeline expires in 2043, while the contract with Spire begins in 2025 and ends in 2035. Idaho Power purchases and stores natural gas with the intent of fulfilling needs as identified for seasonal peaks or to meet system requirements. As of February 9, 2024, Idaho Power had approximately 24.5 million MMBtu of natural gas financially hedged for physical delivery, primarily for the operational dispatch of the Langley Gulch plant through September 2025. Idaho Power plans to manage the procurement of additional natural gas for the peaking units primarily on the daily spot market or from storage inventory as necessary to meet system requirements and fueling strategies. Purchased Power : Idaho Power purchases power in the wholesale market as well as pursuant to long-term power purchase contracts and exchange agreements. The table below presents Idaho Power’s purchased power expenses and volumes for the last three years ended December 31 (in thousands, except for per MWh amounts). Transmission costs, purchases from the Western EIM, and costs from demand response programs are included with wholesale market purchases in the table. Year Ended December 31, 2023 2022 2021 Expense Wholesale market purchases $ 243,319 $ 306,263 $ 142,248 Long-term agreements (including PURPA) 258,212 238,082 251,443 Total purchased power expense $ 501,531 $ 544,345 $ 393,691 MWh purchased Wholesale market purchases 3,278 3,823 3,168 Long-term agreements (including PURPA) 3,749 3,355 3,655 Total MWh purchased 7,027 7,178 6,823 Cost per MWh from wholesale market purchases $ 74.23 $ 80.11 $ 44.90 Cost per MWh from long-term agreement purchases $ 68.87 $ 70.96 $ 68.79 Weighted average cost per MWh - all sources $ 71.37 $ 75.84 $ 57.70 Wholesale Market : To supplement its self-generated power and long-term purchase arrangements, Idaho Power purchases power in the wholesale market based on economics, operating reserve margins, energy risk management program guidelines, and unit availability. Depending on availability of excess power or generation capacity, pricing, and opportunities in the markets, Idaho Power also sells power in the wholesale markets. Idaho Power has two firm multi-year wholesale purchased power contracts to address increased demand during summer months. These agreements total approximately 150 MW per hour during peak summer periods through 2024. Long-term Power Purchase and Exchange Arrangements : Idaho Power has contracts for the purchase of electricity produced by third-party owned generation facilities, most of which produce energy with the use of renewable generation sources such as wind, solar, biomass, small hydropower, and geothermal. The majority of these contracts are entered into as required by federal law under PURPA. For PURPA energy sales agreements, Idaho Power is required to purchase all of the output delivered from the contracted qualifying facilities. The Idaho jurisdictional portion of the costs associated with PURPA contracts is fully recovered through base rates and the PCA mechanism, and the Oregon jurisdictional portion is recovered through base rates and an Oregon power cost adjustment mechanism. Thus, the primary impact of power purchase costs under PURPA contracts is on customer rates and the timing of cash flows. 13 Table of Contents The following table sets forth, as of the date of this report, the resource type and nameplate capacity of Idaho Power's signed agreements for power purchases from PURPA and non-PURPA generating facilities. These agreements have contract terms ranging from one to 35 years. Resource Type Non-PURPA Online (MW) PURPA Online (MW) Total Online (MW) Under Contract but not yet Online (MW) Total Projects under Contract (MW) Wind 101 625 726 — 726 Solar 160 316 476 428 904 Hydropower — 152 152 — 152 Other 35 43 78 — 78 Total Long-term Projects 296 1,136 1,432 428 1,860 Idaho Power has one agreement with a PURPA-qualifying facility solar project expected to be online in 2024. Idaho Power has agreements with three non-PURPA solar projects for 100 MW, 200 MW, and 125 MW, which are scheduled to be online in 2024, 2025, and 2026, respectively. Battery Storage: Idaho Power utilizes batteries primarily to store power generated during periods of lower customer demand and deliver that power to serve customers during peak hours, especially early summer evenings when irrigation pumps and air conditioners drive up electrical demand. In 2023, 131 MW of company-owned battery storage were installed. In April 2023, Idaho Power entered into a 20-year agreement to utilize the storage capacity from a 150-MW battery storage facility scheduled to be online in June 2025. Idaho Power intends for this capacity to supplement a total of 304 MW of company-owned storage that it expects to be online by the end of 2025. Participation in Energy Markets : Idaho Power participates in the Western EIM under which the participating parties enable their systems to interact for automated intra-hour economic dispatch of generation from committed resources to serve loads. The Western EIM is intended to reduce the power supply costs to serve customers through more efficient dispatch of a larger and more diverse pool of resources, to integrate intermittent power from renewable generation sources more effectively, and to enhance reliability. Idaho Power is participating with other stakeholders in different regional forums discussing the potential for developing other energy markets in the western U.S., including development of a potential day-ahead wholesale centralized market, which Idaho Power believes could provide additional benefits through the centralized economic dispatch of resources of participating utilities. Transmission Services Electric transmission systems deliver energy from electric generation facilities to distribution systems for final delivery to customers. Transmission systems are designed to move electricity over long distances because generation facilities can be located hundreds of miles away from customers. Idaho Power’s generating facilities are interconnected through its integrated transmission system and are operated on a coordinated basis to achieve maximum capability and reliability. Idaho Power’s transmission system is directly interconnected with the transmission systems of the BPA, Avista Corporation, PacifiCorp, NorthWestern Energy, and NV Energy. These interconnections, coupled with transmission line capacity made available under agreements with some of those entities, permit the interchange, purchase, and sale of power among entities in the Western Interconnection, the transmission grid covering much of western North America. Idaho Power provides wholesale transmission service for eligible transmission customers on a non-discriminatory basis. Idaho Power is a member of the Western Electricity Coordinating Council, the Western Power Pool, NorthernGrid, and the North American Energy Standards Board. These groups have been formed to more efficiently coordinate transmission reliability and planning throughout the Western Interconnection. Demand for transmission services can be affected by regional market factors, such as loads and generation of utilities in Idaho Power’s region. Transmission to serve Idaho Power's retail customers is subject to the jurisdiction of the IPUC and OPUC for retail rate-making purposes. Idaho Power provides cost-based wholesale access transmission services under the terms of a FERC-approved OATT. Services under the OATT are offered on a non-discriminatory basis such that all potential customers, including Idaho Power, have an equal opportunity to access the transmission system. As required by FERC standards of conduct, Idaho Power's transmission function is operated independently from Idaho Power's energy marketing function. 14 Table of Contents Idaho Power is jointly working with various partners on the development of two significant transmission projects. The Boardman-to-Hemingway project is a proposed 300-mile, high-voltage transmission line between a substation near Boardman, Oregon, and the Hemingway substation near Boise, Idaho. The Gateway West project is a high-voltage transmission line project between a substation located near Douglas, Wyoming, and the Hemingway substation. Both projects are intended to meet future anticipated resource needs and are discussed in Part II, Item 7 – MD&A - "Liquidity and Capital Resources - Capital Requirements" in this report. Resource Planning Integrated Resource Planning: The IPUC and OPUC require that Idaho Power prepare biennially an IRP. Idaho Power filed its most recent 2023 IRP with the IPUC and OPUC in September 2023. Each IRP seeks to forecast Idaho Power's loads and resources for a 20-year period, analyzes potential supply-side, demand-side, and transmission resource options, and identifies potential near-term, mid-term, and long-term actions. The four primary goals of the IRP are to: • identify sufficient resources to reliably serve the growing demand for energy within Idaho Power's service area throughout the 20-year planning period; • ensure the selected resource portfolio balances cost and risk, while including environmental considerations; • give balanced treatment to supply-side and demand-side measures; and • involve the public in the planning process in a meaningful way. During the time between IRP filings, the public and regulatory oversight of the activities identified in the IRP allows for discussion and adjustment of the IRP as warranted. Idaho Power makes periodic adjustments and corrections to the resource plan to reflect economic conditions, anticipated resource development, changes in technology, and regulatory requirements. The load forecast assumptions Idaho Power used in its 2023 IRP are included in the table below, together with the average annual growth rate assumptions used in the prior two IRPs. While assumptions are estimates only and subject to change based on actual customer load ramp-rates, the 2023 IRP assumptions include significant large commercial and industrial additions in the 5-year forecasted annual growth rate, including potential load from new facilities under development by Meta Platforms, Inc. and Micron Technology, Inc. The rate of load growth can impact the timing and extent of development of resources, such as new generation plants or transmission infrastructure, to serve those loads. 5-Year Forecasted Annual Growth Rate 20-Year Forecasted Annual Growth Rate Retail Sales (Billed MWh) Annual Peak (Peak Demand) Retail Sales (Billed MWh) Annual Peak (Peak Demand) 2023 IRP 5.5% 3.7% 2.1% 1.8% 2021 IRP 2.6% 2.1% 1.4% 1.4% 2019 IRP 1.3% 1.4% 1.0% 1.2% The 2023 IRP preferred resource portfolio and action plan adds 8,436 MW of resource capacity partially offset by retirements of 841 MW of coal-fired generation and 706 MW of natural gas generation over the next 20 years to meet energy and capacity needs. The additions to resource capacity include 3,325 MW of solar, 1,800 MW of wind, 1,453 MW of storage, 360 MW of additional energy efficiency, 340 MW of hydrogen, 160 MW from demand response, and 30 MW of geothermal. In addition, the preferred resource portfolio includes Idaho Power's complete exit from coal-fired generation by 2030 and the conversions of multiple jointly-owned coal-fired generation units to add 968 MW of natural gas generation capacity. Of the additional natural gas generation capacity, 706 MW are expected to be retired in 2038, resulting in a net addition of 261 MW of natural gas generation capacity through 2043. To support these resource additions, the preferred portfolio also includes the Boardman-to-Hemingway transmission line in 2026 and three Gateway West transmission line segments phased in with in-service dates from 2028 through 2040. However, as noted in the 2023 IRP, there is considerable uncertainty surrounding the resource sufficiency estimates and project completion dates, including uncertainty around the timing and extent of third-party development of renewable resources, fuel commodity prices, and the actual completion date and ownership allocations of the transmission projects. These uncertainties, as well as others, could result in changes to the desirability of the preferred portfolio and adjustments to the timing and nature of anticipated and actual actions. Energy Efficiency and Demand Response Programs: Idaho Power’s energy efficiency and demand response portfolio is comprised of 22 programs. The energy efficiency programs target energy savings across the entire year, while the demand response programs target system demand reduction in the summer at times of peak loads. The programs are offered to all 15 Table of Contents customer segments and emphasize the wise use of energy, especially during periods of high demand. This energy and demand reduction can reduce or delay the need for new generation and transmission infrastructure. Idaho Power’s programs include: • financial incentives for irrigation customers for either improving the energy efficiency of an irrigation system or installing new energy efficient systems; • energy efficiency programs for new and existing homes including electric heating, ventilation and cooling equipment, as well as energy efficient building techniques, air duct sealing, and energy efficient lighting; • incentives to industrial and commercial customers for acquiring energy efficient equipment, and using energy efficiency techniques for operational and management processes; • demand response programs to reduce peak summer demand through the voluntary cycling of central air conditioners for residential customers, interruption of irrigation pumps, and reduction of commercial and industrial demand through actions taken by business owners and operators; and • participation in the Northwest Energy Efficiency Alliance, which supports market transformation efforts across the region. In 2023, Idaho Power’s energy efficiency programs reduced energy usage by approximately 140,000 MWh compared with 141,000 MWh in 2022. For 2023, Idaho Power had a demand response available capacity of approximately 312 MW. In both 2023 and 2022, Idaho Power expended approximately $42 million and expended $38 million in 2021 on both energy efficiency and demand response programs. Funding for these programs is provided through a combination of the Idaho and Oregon energy efficiency tariff riders, base rates, and the power cost adjustment mechanisms. Energy efficiency program expenditures funded through the riders are reported as an operating expense with an equal amount of revenues recorded in other revenues, resulting in no net impact on earnings. Environmental, Social, and Governance Initiatives Overview: IDACORP’s and Idaho Power’s corporate governance and nominating committee, with considerable focus from the board of directors, is primarily responsible for the oversight of the companies’ ESG initiatives and both are regularly informed of the goals, measures, and results of the companies' ESG programs. Each committee of the board of directors is assigned a portion of the oversight of the companies' ESG programs. Idaho Power has established an internal ESG steering committee led by senior management and composed of a cross-functional team of key employees from multiple departments to oversee ESG activities and inform leadership and the board of directors on ESG-related activities and matters it identifies as material to the company's operations and financial condition. IDACORP and Idaho Power publicly release annual ESG reports and the most current report is located on Idaho Power’s website, together with other information on ESG issues relevant to Idaho Power, including short-, medium-, and long-term CO 2 emission reduction targets. IDACORP's and Idaho Power's 2022 ESG Report released in April 2023 incorporated elements of the Task Force on Climate-Related Financial Disclosures guidelines and the Sustainability Accounting Standards Board repor ting framework, as well as the Edison Electric Institute (EEI) E SG reporting template. Additionally, in 2023 Idaho Power responded to the Climate Disclosure Project (CDP) annual questionnaire, providing emissions data and management plans to address risks associated with climate change. The ESG reports, CDP filing, and related website content are not incorporated by reference into this report. IDACORP’s and Idaho Power’s ESG initiatives include: • establishing responsible management goals and long-term strategies related to the companies’ impact on the environment; such as ◦ the "Clean Today. Cleaner Tomorrow. ®" goal to provide Idaho Power's customers with 100-percent clean energy by 2045; ◦ the sustainability benefits from the Boardman-to-Hemingway and Gateway West transmission projects, which include integrating renewable energy generation and deferring or eliminating the need for development of additional fossil-fueled resources; ◦ integrating renewable resources into Idaho Power's generation mix and identifying and investigating new generation and storage technologies; as part of this effort, Idaho Power has issued RFPs for additional energy resources, including renewables or natural gas resource convertible to hydrogen gas power, and to-date has procured solar power and battery storage as a result of those RFPs; ◦ continuing various environmental stewardship programs along the Snake River, including fish habitat preservation, water temperature reduction, and fish and plant restoration; ◦ wildfire mitigation planning and actions; ◦ wildlife habitat, archaeological and cultural resource, and raptor protection stewardship; 16 Table of Contents • operational excellence in safely providing reliable, affordable, clean energy, including enhancing grid resiliency and reliability; • engaging and empowering Idaho Power’s workforce (including succession planning at all levels, employee development, leadership education, retirement planning education, and providing competitive compensation and benefits, including post-retirement benefits); • promoting a culture of safety, security, and inclusiveness for all employees; • building strong community partnerships for healthy, sustainable economic development in Idaho Power’s service area; and • publicly releasing Idaho Power's annual EEO-1 statement to report its board and employee demographic workforce data. Reducing Carbon Emissions Intensity: Carbon emissions intensity is a measure of the pounds of CO 2 emitted per MWh of energy generated. Idaho Power tracks carbon emissions intensity to measure the impact of its efforts to reduce carbon emissions relative to growing power demand in its service area. Idaho Power has actively engaged in voluntary carbon emissions intensity reduction over the past decade with an original short-term goal to reduce emissions 10-15 percent from the baseline year of 2005 levels. Idaho Power increased the short-term goal to reduce carbon emission intensity by at least 15-20 percent for the period from 2010-2020, and exceeded this goal with an estimated average reduction o f 29 percent over th at period compared with 2005. In 2020, IDACORP’s and Idaho Power’s boards of directors approved an increased short-term goal to reduce carbon emission intensity by 35 percent for the period from 2021-2025 compared with 2005. In 2022, Idaho Power posted its emissions reduction report on its website that established short-, medium-, and long-term targets for further CO 2 reductions. This report also includes target annual power generation levels and associated CO 2 emissions and emissions intensity for the 2021-2040 period. The emissions reduction report is not incorporated in this report. Idaho Power has significantly reduced its CO 2 emissions since the 2005 baseline year, primarily by decreasing its coal generation levels, including terminating coal generation at the North Valmy Unit 1 in 2019 and at the Boardman plant in 2020, and also by upgrading it s hydropower facilities , and through its energy efficiency, demand-side management, and cloud-seeding programs. Idaho Power plans to continue to reduce CO 2 emissions in future years, including a medium-term goal with a targeted 86 percent reduction in annual CO 2 emissions tons by 2030, compared with the 2005 baseline year. In 2019, Idaho Power announced its long-term goal to provide 100 percent clean energy by 2045. Reduction in Coal-Fired Generation: Idaho Power monitors environmental requirements and assesses whether environmental control measures are or remain economically appropriate. In 2017 and 2018, the IPUC and OPUC approved settlement stipulations allowing accelerated depreciation and cost recovery for the North Valmy plant in connection with Idaho Power's plan to end its participation in the coal-fired operation of units 1 and 2. Idaho Power ended its participation in the coal-fired operation of unit 1 in December 2019, as planned, and regulatory orders from the IPUC and OPUC provide for Idaho Power to end its participation in coal-fired operations of unit 2 no later than the end of 2025. In October 2020, Idaho Power and co-owner Portland General Electric ceased coal-fired operations at the Boardman plant, as planned. In June 2022, the IPUC approved Idaho Power's amended application requesting, among other things, authorization to allow the Jim Bridger plant to be fully depreciated and recovered by end-of-year 2030. The details of the IPUC's order relating to the Jim Bridger plant are described more fully in Part II, Item 7 – MD&A – "Regulatory Matters." Regulatory orders from the IPUC and OPUC provide for Idaho Power to cease coal-fired operations at all jointly-owned coal-fired generation plants by the end of 2028. However, as noted previously, Idaho Power's 2023 IRP identified a preferred resource portfolio and action plan that includes the conversion from coal to natural gas of two units at the Jim Bridger plant in 2024, the two units at the North Valmy plant in 2026, and the remaining two units at the Jim Bridger plant in 2030. For more information on the 2023 IRP, refer to "Resource Planning" in this Item 1 – "Business." Idaho Power expects to seek approval from the IPUC and OPUC for any necessary adjustments to plant retirement dates to align with its current resource plan. Climate Change Adaptation : Idaho Power believes its practice of in-depth planning and prudent preparation helps the company adapt to and address the risks of climate change. For more than 100 years, Idaho Power has adapted to changes in temperatures, water conditions, economic impacts, and regulatory requirements. In recent years, Idaho Power has proactively addressed risks associated with climate change through preventative measures. To address the physical impacts of climate change, Idaho Power conducts cloud-seeding operations, implements a WMP, enhances grid resiliency and reliability, and continues to further Snake River shading and in-stream river enhancement projects. Idaho Power also plans for the social and economic impacts of climate change by moving forward toward its carbon emissions reduction goals, continuing efforts to achieve its path away from coal generation, increasing the integration of renewable energy, and enhancing customer and stakeholder communication. Additionally, to plan for the potential regulatory impacts of climate change, Idaho Power considers climate-related impacts in planning efforts, plans and advocates for additional transmission capacity to integrate additional renewable energy onto its 17 Table of Contents system, identifies and investigates new technologies, including battery storage, hydrogen generation, and modular nuclear reactor technology, and evaluates modifications to its pricing structure it believes will help ensure fair pricing for all customers. Environmental Regulation and Costs Idaho Power's activities are subject to a broad range of federal, state, regional, and local laws and regulations designed to protect, restore, and enhance the quality of the environment. Environmental regulation impacts Idaho Power’s operations due to the cost of installation and operation of equipment and facilities required for compliance with environmental regulations, the modification of system operations to accommodate environmental regulations, and the cost of acquiring and complying with permits and licenses. In addition to generally applicable regulations, Idaho Power's jointly-owned coal-fired power plants, natural gas combustion turbine power plants, and hydropower generating plants are subject to a broad range of environmental requirements, including those related to air and water quality, waste materials, and endangered species. For a more detailed discussion of these and other environmental issues, refer to Part II - Item 7 - MD&A - "Environmental Matters" in this report. Environmental Expenditures: Idaho Power’s environmental compliance expenditures will remain significant for the foreseeable future, particularly given the volume of existing and proposed regulations at the federal level. Idaho Power estimates its environmental expenditures, based upon present environmental laws and regulations, will be as follows for the periods indicated, excluding AFUDC (in millions of dollars): 2024 2025-2026 Capital expenditures: License compliance and relicensing efforts at hydropower facilities $ 27 $ 91 Investments in equipment and facilities at thermal plants 2 3 Total capital expenditures $ 29 $ 94 Operating expenses: Operating costs for environmental facilities - hydropower $ 25 $ 49 Operating costs for environmental facilities - thermal 9 21 Total other O&M $ 34 $ 70 Idaho Power anticipates that finalization, implementation, or modification of a number of federal and state rulemakings and other proceedings addressing, among other things, GHGs and endangered species, could result in substantial changes in operating and compliance costs, but Idaho Power is unable to estimate those changes in costs given the uncertainty associated with existing and potential future regulations. Idaho Power expects that it would seek to recover increases in costs through the ratemaking process. Beyond increasing costs generally, these environmental laws and regulations could affect IDACORP's and Idaho Power's results of operations and financial condition if the costs associated with these environmental requirements and potential early plant retirements cannot be fully recovered in rates on a timely basis. Idaho Power is actively pursuing the relicensing of the HCC, its largest hydropower generation source. As of the date of this report, although Idaho Power believes issuance of a new HCC license by the FERC is likely in 2025 or thereafter, Idaho Power is unable to predict the exact timing of issuance by the FERC of any license order or the ultimate capital investment and ongoing operating and maintenance costs Idaho Power will incur in complying with any new license. However, Idaho Power estimates that the annual costs it will incur to obtain a new long-term license for the HCC, including AFUDC, are likely to range from $35 million to $45 million until issuance of the license. Subsequent to the issuance of a new license, Idaho Power expects to incur increased annual capital expenditures and operating and maintenance costs to comply with the requirements of any new license. Human Capital Overview: Idaho Power's purpose is powering lives by safely providing reliable, affordable, clean energy. Idaho Power believes that it will prosper by committing to the needs, safety, and success of its customers, communities, employees, and owners.
