Current report

•Idaho Power continues to focus on timely recovery of costs and earning a reasonable return on investment. In March 2025, Idaho Power provided notice to the IPUC of its intent to file a general rate case in Idaho on or after May 30, 2025. Idaho Power also filed requests with the IPUC for rate changes for the FCA in March and the PCA in April, which if approved would result in a rate decrease of a combined $135.5 million for applicable customer classes. In addition, in March 2025, Idaho Power filed a request with the IPUC for an order authorizing an increase in customer rates of $29.7 million, effective June 1, 2025, to increase cash collection of AFUDC associated with the HCC relicensing project. The IPUC's decisions in these matters are pending.

Current report

Other O&M expenses in the first quarter of 2025 were $7.2 million higher than the first quarter of 2024, partially related to an approximate $3.2 million increase in wildfire mitigation program and related insurance expenses. In addition, other O&M expenses increased $1.8 million due to a decrease in grant funding received for maintenance work in the first quarter of 2025 as compared to the first quarter of 2024. Inflationary pressures on labor-related costs also contributed to the increase in other O&M expenses.

Current report

Non-operating expense, net, increased $2.2 million in the first quarter of 2025 compared with the first quarter of 2024. Higher long-term debt balances and an increase in transmission customer deposits, on which Idaho Power must pay interest to the customer, led to an increase in interest expense. This increase was partially offset by an increase in AFUDC in the first quarter of 2025 compared with the first quarter of 2024, as the average construction work in progress balance was higher.

Current report

•Customers: Customer growth of 2.6 percent during the twelve months ended March 31, 2025, increased retail revenues by $10.8 million in the first quarter of 2025 compared with the same period of 2024.

Current report

•Usage: Overall usage (on a per customer basis) was relatively consistent between the first quarters of 2025 and 2024. Residential usage per customer increased, as lower temperatures in the first quarter of 2025 compared with the first quarter of 2024 led to residential customers to use more energy for heating purposes, but the increase was partially offset by a decrease in industrial usage per customer and the effects of customer mix changes.

Current report

•FCA Mechanism: An increase in the deferral of residential and small commercial customer revenues through the FCA mechanism negatively affected retail revenues by $1.5 million.

Current report

Purchased power expense decreased $37.8 million, or 34 percent, during the first quarter of 2025 compared with the same period of 2024, primarily due to lower wholesale energy market prices in the region. Also, increased system generation led to a decrease in total MWh purchased of 13 percent compared to 2024.

Current report

(2) Includes a negligible amount of expense and generation related to the Salmon diesel-fired generation plant.

Current report

Fuel expense decreased $22.8 million, or 25 percent, in the first quarter of 2025 compared with the same period of 2024, primarily due to a 19 percent decrease in the total average cost per MWh from all sources and a 7 percent decrease in MWh generated from steam and natural gas generation. Hydropower generation increased 21 percent during the first three months of 2025, compared with the same period of 2024, which reduced utilization of steam and natural gas generation to serve load and provide power for wholesale energy sales.

Current report

Other O&M Expenses: Other O&M expenses in the first quarter of 2025 were $7.2 million higher than the first quarter of 2024, partially related to an approximate $3.2 million increase in wildfire mitigation program and related insurance expenses. In addition, other O&M expenses increased $1.8 million due to a decrease in grant funding received for maintenance work in the first quarter of 2025 as compared with the first quarter of 2024. Inflationary pressures on labor-related costs also contributed to the increase in other O&M expenses.

IDACORP Equity Programs: In March 2025, IDACORP executed FSAs under its ATM offering program with various counterparties, at an aggregate gross sales price of $52 million. At March 31, 2025, IDACORP's cumulative aggregate gross sales price of executed and outstanding FSAs under its ATM offering program was $145 million, and $155 million in shares of IDACORP’s common stock remained available for issuance. IDACORP may settle the FSAs at any time up to their respective maturity dates of approximately one year following execution. If IDACORP had elected to physically settle the FSAs as of April 25, 2025, by delivering shares of common stock, cash proceeds would have been approximately $144 million. Actual cash proceeds, if any, for settlement of the FSAs will depend on the method and timing IDACORP elects for settlement. For more detailed information about IDACORP's equity transactions, see Note 6 - "Common Stock" to the condensed consolidated financial statements included in this report. Depending on market conditions, its financial and regulatory strategy, and other factors, IDACORP could determine to issue additional equity securities in 2025.

For more detailed information about Idaho Power First Mortgage Bonds, see Note 5 - "Long-term Debt" to the condensed consolidated financial statements included in this report.

Current report

SWIP-N Transmission Line: In February 2025, Idaho Power entered into a commitment to become a partial owner of SWIP-N, a planned 285-mile, high-voltage transmission line between the Robinson Summit Substation near Ely, Nevada, and the Midpoint Substation near Jerome, Idaho. Upon the project being placed into service, the applicable agreements provide that Idaho Power will purchase an approximate 11 percent ownership interest in the project, entitling Idaho Power to approximately 11 percent of the total capacity of the SWIP-N line. In addition, Idaho Power entered into a capacity entitlement agreement entitling Idaho Power to approximately 11 percent of additional capacity on the SWIP-N line over a 40-year term commencing upon the project being placed in service. Idaho Power expects construction of the project to commence as early as 2025 and take approximately two years to complete. Idaho Power is responsible for approximately 11 percent of the total costs to develop and construct the project. The capital requirements table above includes Idaho Power's share of the costs to develop and construct the project. The project agreements do not require Idaho Power to incur any costs to purchase its ownership interest or begin paying for capacity under the capacity entitlement agreement until the line is in service. Idaho Power has an option to purchase the ownership interest associated with such capacity entitlement upon expiration of the 40-year term.

Current report

Jackalope Wind Project: In October 2024, Idaho Power entered into agreements with a counterparty and certain of its affiliates to develop the Jackalope Project, which consists of (i) a 35-year PPA between Jackalope Wind, LLC and Idaho Power, supplying approximately 300 MW of generation to Idaho Power's system from a wind-powered generation facility located in Sweetwater County, Wyoming, and (ii) a co-located wind turbine generator power plant to be owned by Idaho Power, providing approximately 300 MW of generation. The capital requirements table above includes Idaho Power's share of the costs to develop and construct the project but does not include any of the expected costs of the PPA. As of the date of this report, Idaho Power expects the Jackalope Project to begin operations in 2027.

Current report

In December 2024, Idaho Power filed an application with the IPUC for the Jackalope Project, one of the bids from an RFP to procure resources for its anticipated energy and capacity needs in 2027. The Jackalope Project consists of (i) a 35-year PPA between Jackalope Wind, LLC and Idaho Power, supplying approximately 300 MW of generation to Idaho Power's system, and (ii) a wind turbine generator power plant to be owned by Idaho Power, providing approximately 300 MW of generation. In its application, Idaho Power requested that the IPUC approve the PPA and grant a CPCN for the wind turbine generator power plant. Several parties have intervened in this case. As of the date of this report, the case remains pending.

Current report

Also in December 2024, Idaho Power filed an application with the IPUC to grant a CPCN for Idaho Power to acquire and own two battery storage facilities with a total of 100 MW of operating capacity to address Idaho Power's identified capacity deficiency in 2026. As of the date of this report, the case remains pending. These battery storage facilities are in addition to the 150 MW of battery storage to be acquired and owned by Idaho Power for which the IPUC approved a CPCN in November 2024.

Current report

In March 2025, Idaho Power filed an application with the IPUC to grant a CPCN for Idaho Power to acquire an ownership interest, including the rights to 250 MW of northbound capacity, in SWIP-N, a planned 285-mile, high-voltage transmission line between the Robinson Summit Substation near Ely, Nevada, and the Midpoint Substation near Jerome, Idaho. In its application, Idaho Power also requested that the IPUC approve the company's utilization of an additional 250 MW of rights to northbound capacity on SWIP-N. As of the date of this report, the case remains pending.

Current report

In March 2025, Idaho Power filed an application with the IPUC for an order (1) approving the 20-year PPA with Crimson Orchard Solar LLC supplying the 100 MW output to Idaho Power, (2) approving the 20-year energy storage agreement (ESA) with Crimson Orchard Solar for 100 MW of dispatchable energy storage capacity, and (3) acknowledging the lease accounting necessary to facilitate the transaction and that the resulting expenses associated with both the PPA and the ESA are prudently incurred for ratemaking purposes. As of the date of this report, the case remains pending.

Current report

Micron Fab Special Contract: In December 2024, Idaho Power filed an application with the IPUC for approval of a special contract for electric service for Micron Idaho Semiconductor Manufacturing (Triton) LLC, a subsidiary of Micron, for electric service for Micron's new memory manufacturing fabrication complex located in Boise. The special contract anticipates a significant increase in load on Idaho Power's system that will ramp over a number of years beginning in 2026. Following the intervention of several parties, the IPUC directed IPUC staff to propose a schedule for the case, including a technical hearing. As of the date of this report, the case remains pending.

Current report

In March 2025, the EPA announced a set of proposed regulatory actions relating to environmental laws and regulations, many of which will impact Idaho Power if they are implemented. The proposed regulatory actions relate to the following laws and regulations, among others: the EPA's 2009 endangerment finding regarding six greenhouse gases; the Clean Power Plan 2.0; the Mercury and Air Toxics Standards; the Greenhouse Gas Reporting Program; effluent limitations guidelines and standards for the Steam Electric Power Generating Industry; the National Ambient Air Quality Standards for Particulate Matter (PM2.5); the Regional Haze Program; the “Good Neighbor Plan” and related State Implementation Plans; the coal ash program; and the definition of "Waters of the United States," which impacts applicability of the CWA to certain wetlands and water bodies. The

Current report

EPA has not yet taken official action on any of these items. Idaho Power will continue to actively monitor these proposals and any other pending or potential environmental regulations related to environmental matters that may have an impact on its future operations. Given uncertainties regarding the outcome and timing for these EPA proposals, Idaho Power is unable to estimate the impact on Idaho Power of any such proposals.

Current report

NEPA is a federal law that requires federal agencies to consider the environmental impacts of their actions and decisions. NEPA applies to Idaho Power’s transmission and distribution lines that are located on federal land, as well as other company activities involving federal actions. The Council on Environmental Quality (CEQ) under previous Presidential Administrations had issued guidance to federal agencies in issuing their own regulations regarding the implementation of NEPA for projects under their jurisdiction. However, in November 2024, the DC Circuit Court of Appeals ruled that the CEQ lacks the authority to issue binding regulations implementing NEPA (Marin Audubon Society v. Federal Aviation Administration). Subsequently, the current Presidential Administration issued Executive Order 14154, which revoked the CEQ’s authority to issue NEPA regulations and directed the CEQ to rescind all NEPA regulations. As a result, the CEQ issued an interim final rule in February 2025 to remove all CEQ NEPA implementing regulations. The interim final rule became effective on April 11, 2025. The impact that revocation of the CEQ’s NEPA regulations will have on agency-specific NEPA procedures is unclear, and as a result, Idaho Power is unable to predict what impact these actions will have on Idaho Power and its operations.

Current report

Executive Orders of the Current Presidential Administration

Current report

Since the start of the current Presidential Administration in January 2025, the Administration has released several executive orders that may impact Idaho Power. These executive orders include, but are not limited to, orders regarding tariffs, the electric grid, the coal industry, revocation of executive orders of prior Presidential Administrations, and other orders intended to regulate international trade, strengthen the U.S. energy industry, and/or promote deregulation, including with respect to environmental and energy-related regulations. The outcome of these executive orders and U.S. federal agencies' review of regulations covered by executive orders is difficult to predict.

Current report

In addition, the court system has become more active in reviewing Presidential and agency actions, resulting in even less certainty as to the outcome and durability of rules that are administratively implemented. Changes to or elimination of regulations may lower Idaho Power's costs of operating and maintaining fossil fuel-fired generation plants and constructing transmission lines, due to the reduction of potential environmental infrastructure upgrades or conversions or reduction or elimination of permitting requirements. More strict or robust regulations, or additional regulations, such as tariffs on supplies and materials that Idaho Power purchases, on the other hand, would likely increase Idaho Power's costs of operating and maintaining its facilities, and could impact Idaho Power's plans and construction activities related to its capital projects, which could lead to substantially higher costs and delays in construction.

Current report

Executive orders may be affected by Congressional action. Further, state and local governmental authorities could choose to challenge or replace the federal regulations or bolster or undermine environmental compliance and enforcement efforts at the local level. Therefore, as of the date of this report, and except as specifically described in this MD&A, Idaho Power is uncertain whether and to what extent the orders, any new or future executive orders, and the implementation of these and any future executive orders could affect its business, results of operations, and financial condition. Idaho Power will continue to monitor actions associated with or resulting from executive orders and new or revised legislation or regulation.

Current report

In April 2025, Idaho enacted the Wildfire Standard of Care Act (Idaho Code § 61-1801 through 1808), which will become effective on July 1, 2025. The Act requires Idaho electric public utilities to prepare wildfire mitigation plans annually to mitigate wildfire risk, submit the plans to the IPUC for review and approval, and implement the plans upon IPUC approval. An electric utility's wildfire mitigation plan approved by the IPUC establishes the utility's duty to its shareholders and the public with respect to wildfire risk. For any civil action where wildfire-related damages are being sought against an electric utility, the Act establishes a rebuttable presumption that the utility acted without negligence if, with respect to the cause of the wildfire, the utility reasonably implemented an IPUC-approved wildfire mitigation plan. The rebuttable presumption extends to any act or omission taken in reasonable accordance with the approved wildfire mitigation plan in effect at the time the fire ignited, regardless of the content of any prior wildfire mitigation plans. The Act provides that, with certain exceptions, the remedies set out in the Act are the exclusive civil remedies available against an electric utility for damages resulting from any act or omission related to an IPUC-approved wildfire mitigation plan. The Act also permits electric utilities, upon certain conditions, to access privately-owned land or easements or rights-of-way on land owned by the state, a federal agency, or a tribal government for purposes of performing work in accordance with their approved wildfire mitigation plans. In addition, electric utilities may inspect, repair, or upgrade their assets, infrastructure, or facilities on such land and are protected from liability with respect to such access, subject to limitations set forth in the Act. Idaho Power intends to prepare an Idaho-specific WMP that integrates the requirements of the Act and to file the Idaho WMP with the IPUC after the Act becomes effective. The Act provides up to six months for the IPUC to review and approve a WMP after it is filed.

Previous report

The net increase in retail revenues per MWh, net of associated power supply costs and power cost adjustment and FCA mechanisms, increased operating income by $19.3 million in the third quarter of 2024 compared with the third quarter of 2023.

Previous report

Total other O&M expenses in the third quarter of 2024 were $20.3 million higher than the third quarter of 2023, partially related to approximately $4 million of increased pension-related expenses and an approximate $6 million increase in wildfire mitigation program and related insurance expenses. Both of these increases in expenses were partially offset by increases in retail revenues, as more costs are now recovered in base rates pursuant to the 2023 Settlement Stipulation. However, revenues related to these increased costs are not collected at the same rate that the expenses are incurred in the interim periods throughout the year due to the impact of volume-based rates and associated revenues. Inflationary pressures on labor-related costs also contributed to the increase in other O&M expenses. These increases in other O&M expenses were partially offset by a $2.9 million deferral of other O&M expenses related to the conversion from coal to natural gas for two units at the Jim Bridger plant.

Previous report

Non-operating expense, net, decreased $2.4 million in the third quarter of 2024 compared with the third quarter of 2023. AFUDC increased in the third quarter of 2024 compared with the third quarter of 2023, as the average construction work in progress balance was higher, and interest income increased due to higher average cash balances and interest rates. These increases were partially offset by an increase in interest expense on long-term debt in the third quarter of 2024 compared with the third quarter of 2023, due primarily to an increase in long-term debt balances. Also offsetting the increases, Idaho Power's earnings from its investment in BCC decreased $2.2 million in the third quarter of 2024 compared with the third quarter of 2023, due to a decrease in the amount included and recovered in base rates pursuant to the 2023 Settlement Stipulation.

Previous report

At Idaho Power, customer growth increased operating income by $17.1 million in the first nine months of 2024 compared with the first nine months of 2023. The benefit from customer growth was partially offset by a decrease in usage per retail customer of $0.8 million, as higher usage per customer in the second and third quarters of 2024 was more than offset by lower usage per customer in the first quarter of 2024. Overall, usage per customer was relatively flat for most customer classes.

Previous report

Transmission wheeling-related revenues, net of PCA impacts, decreased $3.0 million during the first nine months of 2024 compared with the first nine months of 2023. Effective January 1, 2024, financial settlement of transmission line losses are subject to the PCA mechanism, as approved in the 2023 Settlement Stipulation, resulting in a smaller contribution of those revenues to net income compared with the first nine months of 2023 when the financial settlement of transmission line losses was not subject to the PCA mechanism.

Previous report

Total other O&M expenses in the first nine months of 2024 were $47.9 million higher than the first nine months of 2023, partially related to approximately $13 million of increased pension-related expenses and an approximate $22 million increase in wildfire mitigation program and related insurance expenses. Both of these increases in expenses were partially offset by increases in retail revenues, as more costs are now recovered in base rates pursuant to the 2023 Settlement Stipulation; however, revenues related to these increased costs are not collected at the same rate that the expenses are incurred in the interim periods throughout the year. On a full-year basis for 2024, Idaho Power expects other O&M expenses related to its employee pension plans and its wildfire mitigation program and related insurance to increase approximately $18 million and $30 million, respectively, compared with 2023. Inflationary pressures on labor-related costs also contributed to the increase in other O&M expenses. These increases were partially offset by a $9.1 million increase in deferral of other O&M expenses related to the conversion from coal to natural gas for two units at the Jim Bridger plant.

Previous report

Depreciation expense increased $21.8 million for the first nine months of 2024 compared with the first nine months of 2023 due primarily to an increase in plant-in-service.

Previous report

Non-operating expense, net, decreased $0.2 million in the first nine months of 2024 compared with the first nine months of 2023. AFUDC increased in the first nine months of 2024 compared with the first nine months of 2023, as the average construction work in progress balance was higher. In addition, interest income increased due to higher average cash balances and interest rates compared with the same period in 2023. These increases were partially offset by an increase in interest expense on long-term debt in the first nine months of 2024 compared with the first nine months of 2023, due primarily to an increase in long-term debt balances. Also offsetting the increases, Idaho Power's earnings from its investment in BCC decreased $5.5 million in the first nine months of 2024 compared with the first nine months of 2023, due to a decrease in the amount included and recovered in base rates pursuant to the 2023 Settlement Stipulation.

Previous report

The 2025 preliminary IRP assumptions included in the above table do not include two potential significant large energy-intensive projects in the 5-year forecasted annual growth rate, as Idaho Power only recently delivered the results of its infrastructure construction and generation studies and associated cost estimates to those two customers. As of the date of this report, neither customer has executed an agreement to commence construction of electrical facilities. However, were either potential customer to execute an agreement, it would increase Idaho Power's forecast of retail sales growth.

•Customers: Customer growth increased retail revenues by $12.0 million and $28.5 million in the third quarter and first nine months of 2024, respectively, compared with the same periods of 2023.

Previous report

•Usage: Higher usage (on a per customer basis) in most customer classes increased retail revenues by $4.0 million and $1.4 million, respectively, for the three and nine months ended September 30, 2024, compared with the same periods in 2023. Warmer and drier summer weather led to increased usage per residential customer for cooling and increased usage per irrigation customer for pump irrigation during the three months ended September 30, 2024, compared with the same period in 2023. During the first nine months of 2024, usage per residential customer decreased, as more moderate temperatures from January through May 2024 led residential customers to use less energy for heating purposes. However, warmer weather during the summer of 2024 led to an increase in energy usage per residential customer for cooling purposes, and an increase in energy usage per irrigation customer, which more than offset the decrease in usage per residential customer from January through May 2024.

Previous report

Transmission Wheeling-Related Revenues: Transmission wheeling-related revenues decreased $0.7 million, or 3 percent, and $1.6 million, or 3 percent, during the third quarter and first nine months of 2024, respectively, compared with the same periods of 2023, primarily due to lower revenue from the financial settlement of transmission line losses as a result of lower power prices in the western United States. Also, Idaho Power's OATT rates were approximately 2 percent lower in the first nine months of 2024 compared to the first nine months of 2023. Effective January 1, 2024, financial settlement of transmission line losses are subject to the PCA mechanism, as approved in the 2023 Settlement Stipulation, reducing the potential net income impact of those transmission-related revenues.

Previous report

Purchased power expense decreased $28.3 million, or 20 percent, and $83.5 million, or 21 percent, during the third quarter and first nine months of 2024, respectively, compared with the same periods of 2023. Increased system generation led to a decrease in total MWh purchased of 24 percent and 12 percent for the third quarter and first nine months of 2024, respectively, compared with the same periods of 2023.

Previous report

Fuel expense increased $1.7 million, or 2 percent, and decreased $3.5 million, or 2 percent, in the third quarter and first nine months of 2024, respectively, compared with the same periods of 2023. In both the third quarter and first nine months of 2024, steam and natural gas generation increased to serve load and provide power for wholesale energy sales, compared with the same periods of 2023. The impact of this generation increase on fuel expense was partially offset in the third quarter by lower natural gas market prices and more than offset during the first nine months of 2024 by lower natural gas market prices compared with the same periods of 2023.

Previous report

Other O&M Expenses: Total other O&M expenses increased $20.3 million and $47.9 million in the third quarter and first nine months of 2024, respectively, compared with the same periods of 2023, partially related to approximately $4 million and $13 million, respectively, of increased pension-related expenses and approximately $6 million and $22 million, respectively, of increased wildfire mitigation program and related insurance expenses. Both of these increases in expenses were partially offset by increases in retail revenues, as more costs are now recovered in base rates pursuant to the 2023 Settlement Stipulation. However, revenues related to these increased costs are not collected at the same rate that the expenses are incurred in the interim periods throughout the year due to the impact of volume-based rates and associated revenues. Inflationary pressures on labor-related costs also contributed to the increase in other O&M expenses in the third quarter and first nine months of 2024, compared with the same periods of 2023. During the three and nine months ended 2024 compared with the same periods in 2023, these increases in other O&M expenses were partially offset by a $2.9 million and $9.1 million deferral of other O&M expenses, respectively, related to the conversion from coal to natural gas for two units at the Jim Bridger plant.

Current wording

The table below provides a reconciliation of net income attributable to IDACORP for the three months ended March 31, 2025, from the same period in 2024 (items are in millions and are before related income tax impact unless otherwise noted):

Previous wording

IDACORP's net income increased $8.3 million for the third quarter of 2024 compared with the third quarter of 2023, due primarily to higher net income at Idaho Power.

Current wording

IDACORP's net income increased $11.4 million for the first quarter of 2025 compared with the first quarter of 2024, due primarily to higher net income at Idaho Power.

Previous wording

The net increase in retail revenues per MWh, net of associated power supply costs and power cost adjustment and FCA mechanisms, increased operating income by $44 million in the first nine months of 2024 compared with the first nine months of 2023. This benefit was due primarily to an overall increase in Idaho base rates, effective January 1, 2024, per the terms of the 2023 Settlement Stipulation.

Current wording

A net increase in retail revenues per MWh, net of power cost adjustment mechanisms, increased operating income by $11.3 million in the first quarter of 2025 compared with the first quarter of 2024. This benefit was due primarily to an overall increase in Idaho base rates, effective January 1, 2025, per the 2024 Idaho Limited-Issue Rate Case. For more information on the 2024 Idaho Limited-Issue Rate Case, see Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2024 Annual Report.

Previous wording

At Idaho Power, customer growth increased operating income by $7.4 million in the third quarter of 2024 compared with the third quarter of 2023, as the number of Idaho Power customers grew by approximately 16,500, or 2.6 percent, during the twelve months ended September 30, 2024. Usage per retail customer increased operating income by $3.1 million in the third quarter of 2024 compared with the third quarter of 2023. While there was an increase in usage per customer for most retail customer classes, usage per residential and irrigation customers were the primary contributors. Higher temperatures and lower precipitation compared with the third quarter of 2023 led residential customers to use more energy for cooling purposes and irrigation customers to run irrigation pumps more frequently.

Current wording

At Idaho Power, customer growth increased operating income by $7.3 million in the first quarter of 2025 compared with the first quarter of 2024, as the number of Idaho Power customers grew by approximately 16,500, or 2.6 percent, during the twelve months ended March 31, 2025. Usage per retail customer was relatively consistent in the first quarter of 2025 compared with the first quarter of 2024. Residential usage per customer increased, as lower temperatures in the first quarter of 2025 compared with the first quarter of 2024 led residential customers to use more energy for heating purposes, but the increase was offset by a slight decrease in industrial usage per customer and the effects of customer mix changes. An increase in the deferral of residential and small commercial customer revenues through the FCA mechanism negatively affected retail revenues by $1.5 million.

Previous wording

Depreciation expense increased $5.6 million in the third quarter of 2024 compared with the third quarter of 2023 due primarily to an increase in plant-in-service.

Current wording

Depreciation expense increased $5.8 million in the first quarter of 2025 compared with the first quarter of 2024, due primarily to an increase in plant-in-service.

Previous wording

Other changes in operating revenues and expenses, net, increased operating income by $3.3 million in the third quarter of 2024 compared with the third quarter of 2023, due primarily to a decrease in net power supply expenses that were not deferred for future recovery in rates through Idaho Power's power cost adjustment mechanisms, which increased other changes in operating revenues and expenses, net, compared with the same period in 2023. More moderate and less volatile wholesale natural gas and power market prices in the western United States and increased wholesale energy sales decreased Idaho Power's net power supply expenses in the third quarter of 2024 compared with the third quarter of 2023.

Current wording

Other changes in operating revenues and expenses, net, increased operating income by $1.9 million in the first quarter of 2025 compared with the first quarter of 2024, due primarily to a decrease in net power supply expenses that were not deferred for future recovery in rates through Idaho Power's PCA mechanism, which increased other changes in operating revenues and expenses, net, compared with the same period in 2024. More moderate and less volatile wholesale natural gas and power market prices in the western United States decreased Idaho Power's net power supply expenses in the first quarter of 2025 compared with the first quarter of 2024.

Previous wording

The increase in income tax expense was principally the result of higher income before income taxes, partially offset by an increase in additional ADITC amortization. Based on Idaho Power's current expectations of full-year 2024 results, Idaho Power recorded $2.5 million of additional ADITC amortization under its Idaho regulatory settlement stipulation during the third quarter of 2024, but recorded no additional ADITC amortization during the same period in 2023.

Current wording

The decrease in income tax expense was principally the result of an increase in additional ADITC amortization. Based on Idaho Power's current expectations of full-year 2025 financial results, Idaho Power recorded $19.3 million of additional ADITC amortization under its Idaho regulatory settlement stipulation during the first quarter of 2025, compared with $12.5 million of additional ADITC amortization during the same period in 2024.

Previous wording

•Regulation of Rates and Cost Recovery; Rate Case Filings: The prices that Idaho Power is authorized to charge for its electric and transmission service are a critical factor in determining IDACORP's and Idaho Power's results of operations and financial condition. Those rates are established by state regulatory commissions and the FERC and are intended to allow Idaho Power an opportunity to recover its expenses and earn a reasonable return on investment. Idaho Power is focused on timely recovery of its costs through filings with its regulators, working to put in place innovative regulatory mechanisms, and prudent management of expenses and investments. The 2023 Settlement Stipulation provides for the accelerated amortization of ADITC, if necessary, to help achieve a minimum 9.12 percent Idaho ROE. The 2023 Settlement Stipulation also provides for the potential sharing between Idaho Power and its Idaho customers of Idaho-jurisdictional earnings in excess of a 9.6 percent Idaho ROE. The specific terms of the 2023 Settlement Stipulation are described in Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2023 Annual Report.

Previous wording

To address the regulatory lag in recovery of costs primarily associated with Idaho Power’s current and anticipated significant infrastructure investments, including those that are intended to help meet projected near-term capacity deficits, Idaho Power filed a limited-issue rate case in Idaho on May 31, 2024. Idaho Power expects the processing of this limited-issue rate case in Idaho will span at least seven months before new rates would be in effect. In December 2023, Idaho Power made a general rate case filing in Oregon, which is described more fully in Note 3 - "Regulatory Matters" to the condensed consolidated financial statements included in this report. In September 2024 the OPUC approved the 2024 Oregon Settlement Stipulations related to Idaho Power's Oregon general rate case filing.

Current wording

To address the regulatory lag in recovery of costs primarily associated with Idaho Power’s current and anticipated significant infrastructure investments, including those that are intended to help meet projected near-term capacity deficits, in March 2025 Idaho Power provided notice to the IPUC of its intent to file a general rate case in Idaho on or after May 30, 2025. Idaho Power expects the processing of a general rate case would span at least seven months before new rates would be in effect.

Previous wording

•Rate Base Growth and Infrastructure Investment: The rates established by the IPUC, OPUC, and FERC are determined with the intent to provide an opportunity for Idaho Power to recover authorized operating expenses and depreciation and earn a reasonable return on “rate base.” Rate base is generally determined by reference to the original cost (net of accumulated depreciation) of utility plant in service and certain other assets, subject to various adjustments for deferred income taxes and other items. Over time, rate base is increased by additions to utility plant in service and reduced by depreciation of utility plant and write-offs as authorized by the IPUC and OPUC. Idaho Power is pursuing significant enhancements to its utility infrastructure in an effort to maintain system reliability, ensure an adequate supply of electricity, and provide service to new customers, including major ongoing transmission projects such as the B2H and GWW projects. Idaho Power's existing hydropower and thermal generation facilities also require continuing upgrades and equipment replacement, and the company is undertaking a significant relicensing effort for the HCC, its largest hydropower generation resource. Idaho Power is seeking timely inclusion of completed capital projects into rate base as part of the 2024 Idaho Limited-Issue Rate Case and intends to continue to do so in future general rate cases or other appropriate regulatory proceedings.

Previous wording

3,751 MW, set in June 2021. Idaho Power believes that existing and sustained growth in customers, load, and peak demand for electricity, along with changes in the regional transmission markets that have constrained the availability of transmission outside Idaho Power’s service area to import energy during peak load periods, require Idaho Power to increase its investment in capacity resources, transmission, and distribution infrastructure. This includes the B2H and GWW transmission projects, along with other capacity, energy, and transmission resource procurements, described in "Liquidity and Capital Resources" in this MD&A.

Current wording

Customer growth has contributed to increases in peak loads experienced in recent years. For example, Idaho Power's highest all-time winter peak demand of 2,719 MW occurred on January 16, 2024, and on July 22, 2024, Idaho Power reached a new all-time summer peak demand of 3,793 MW. Idaho Power's prior all-time peak demand was 3,751 MW, set in June 2021.

•Weather Conditions: Weather and agricultural growing conditions have a significant impact on Idaho Power's energy sales. Relatively low winter and high summer temperatures result in greater energy use for heating and cooling, respectively. During the agricultural growing season, which in large part occurs during the second and third quarters of each year, irrigation customers use electricity to operate irrigation pumps, and weather conditions, such as a prolonged winter, can impact the timing and extent of use of those pumps. Idaho Power also has tiered rates and seasonal rates, which contribute to increased revenues during higher-load periods, most notably during the third quarter of each year when overall customer demand is highest. Much of the adverse or favorable impact of weather on sales of energy to residential and small commercial customers is mitigated through the FCA mechanism, which is described in Note 3 - "Regulatory Matters" to the condensed consolidated financial statements included in this report.

Further, as Idaho Power's hydropower facilities comprise over one-half of Idaho Power's nameplate generation capacity, precipitation levels impact the mix of Idaho Power's generation resources. When hydropower generation decreases, Idaho Power must rely on more expensive generation sources and purchased power. When favorable hydropower generating conditions exist for Idaho Power, they also may exist for other Pacific Northwest hydropower facility operators, lowering regional wholesale market prices and impacting the revenue Idaho Power receives from wholesale energy sales. Much of the adverse or favorable impact of this volatility is addressed through the Idaho and Oregon power cost adjustment mechanisms, which mitigate in large part the impact on earnings. For 2024, Idaho Power expects generation from its hydropower resources to be in the range of 7.0 million to 7.5 million MWh, compared with actual generation of 6.5 million MWh in 2023 and a 30-year average annual total of approximately 7.6 million MWh.

•Mitigation of Impact of Fuel and Purchased Power Expense: In addition to hydropower generation, Idaho Power relies significantly on natural gas and coal to fuel its generation facilities, long-term power purchase agreements (including PURPA agreements), and power purchases in the wholesale markets. Fuel costs are impacted by electricity sales volumes, the terms and conditions of contracts for fuel, Idaho Power's generation capacity, the availability of hydropower generation resources, transmission capacity, energy market prices, and Idaho Power's hedging program for managing fuel costs. Purchased power costs are impacted by the terms and conditions of contracts for purchased power, the rate of expansion of alternative energy generation sources such as wind or solar energy, generation resource maintenance outages, wholesale energy market prices, transmission availability, and the outcome of Idaho Power's hedging programs. The Idaho and Oregon power cost adjustment mechanisms mitigate in large part the potential adverse earnings impacts to Idaho Power of fluctuations in power supply costs. However, collection from customers or return to customers of most of the difference between actual power supply costs compared with those included in retail rates is deferred to a subsequent period, which can affect Idaho Power’s operating cash flow and liquidity until those costs are recovered from or returned to customers.

•Regulatory and Environmental Compliance Costs; Coal Plant Retirements: Idaho Power is subject to extensive federal and state laws, policies, and regulations, as well as regulatory actions and audits by agencies and quasi-governmental agencies, including the FERC, the North American Electric Reliability Corporation, and the Western Electricity Coordinating Council. Compliance with these requirements directly influences Idaho Power's operating environment and affects Idaho Power's operating costs. Moreover, environmental laws and regulations may increase the cost of constructing new facilities, may increase the cost of operating generation plants, may require that Idaho Power install additional pollution control devices at existing generating plants, may result in penalties for non-compliance, even where inadvertent, or may require that Idaho Power curtail or cease operating certain generation plants. Idaho Power expects to spend significant amounts on environmental compliance and controls for the foreseeable future. Due to economic factors in part associated with the costs of compliance with environmental regulation, Idaho Power accelerated the retirement date of its North Valmy plant, ceasing coal-fired operations at one unit in 2019 and planning to cease its participation in coal-fired operations at the remaining unit by year-end 2025. Idaho Power's jointly-owned coal plant in Boardman, Oregon, ceased operations as planned in October 2020. In 2022, the IPUC approved Idaho Power's request to allow the coal-related assets at the Jim Bridger plant to be fully depreciated and recovered by end-of-year 2030. 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. Units 1 and 2 at the Jim Bridger plant were successfully converted to natural gas in the second quarter of 2024. In July 2024, Idaho Power executed an agreement with its co-owner to facilitate the planned conversion of the two units at the North Valmy plant from coal to natural gas by mid-2026.

•Wildfire Mitigation Efforts: In recent years, the western United States has experienced an increasing number of wildfires of unprecedented severity. A variety of factors have contributed to this trend including climate change, increased wildland-urban interfaces, historical land management practices, and overall wildland and forest health. Idaho Power is taking a proactive approach to wildfire risk in its service area and transmission corridors. Idaho Power has adopted a WMP that outlines actions Idaho Power is taking or is working to implement to reduce wildfire risk and to strengthen the resiliency of its transmission and distribution system to wildfires. Idaho Power's approach to achieve these objectives includes identifying areas subject to elevated risk; system hardening programs, vegetation management, and field personnel practices to mitigate wildfire risk; incorporating current and forecasted weather and field conditions into operational practices; public safety power shutoff protocols; and evaluating the performance and effectiveness of the strategies identified in the WMP through metrics and monitoring. Idaho Power has a regulatory mechanism that allows the company to defer, for future amortization, the Idaho jurisdictional share of certain actual incremental O&M expenses necessary to implement the WMP. In January 2024, the OPUC authorized Idaho Power's request to defer the Oregon jurisdictional share of costs associated with the WMP for the 12-month period beginning December 29, 2022, and ending on December 28, 2023. The WMP regulatory deferrals are described in more detail in Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2023 Annual Report.

Previous wording

Changes in rates, changes in customer demand, customer growth, and changes in FCA mechanism revenues are the primary reasons for fluctuations in retail revenues from period to period. The primary influences on customer demand of electricity are weather, economic conditions, and energy efficiency. Extreme temperatures increase sales to customers who use electricity for cooling and heating, while moderate temperatures decrease sales. Precipitation levels and the timing of precipitation during the agricultural growing season also affect sales to customers who use electricity to operate irrigation pumps. Rates are also seasonally adjusted, providing for higher rates during peak load periods, and residential customer rates are tiered, providing for higher rates based on higher levels of usage. The seasonal and tiered rate structures contribute to seasonal fluctuations in revenues and earnings.

Previous wording

Retail revenues increased $27.4 million and $85.7 million during the third quarter and first nine months of 2024, respectively, compared with the same periods in 2023. The factors affecting retail revenues during the periods are discussed below.

Current wording

Retail revenues increased $13.1 million during the first quarter of 2025 compared with the same period in 2024. The factors affecting retail revenues during the periods are discussed below.

Previous wording

•Rates: Average customer rates, excluding amounts related to the power cost adjustment mechanisms, increased retail revenues by $34.4 million and $74.2 million, respectively, for the three and nine months ended September 30, 2024, compared with the same periods in 2023, due primarily to the January 1, 2024 rate increase for Idaho Power's retail customers under the 2023 Settlement Stipulation. Customer rates also include the collection from customers of amounts related to the power cost adjustment mechanisms, which decreased revenues by $10.8 million and increased revenues by $11.8 million in the third quarter and first nine months of 2023, respectively, compared with the same periods of 2023. The amount collected from customers in rates under the power cost adjustment mechanisms has relatively little effect on operating income as a corresponding amount is recorded as expense in the same period it is collected through rates. FCA revenue accrued in the three and nine months ended September 30, 2024, decreased by

Current wording

•Rates: Customer rates, excluding revenues related to power cost adjustment mechanisms, increased retail revenues by $11.3 million for the first three months of 2025 compared with the same period in 2024, due primarily to an overall increase in Idaho base rates, effective January 1, 2025, per the 2024 Idaho Limited-Issue Rate Case. Customer rates also include the collection from customers of amounts related to the power cost adjustment mechanisms, which decreased revenues by $8.3 million in the first quarter of 2025 compared with the same period of 2024. The amount collected from customers in rates under the power cost adjustment mechanisms has relatively little effect on operating income as a corresponding amount is recorded as expense in the same period it is collected through rates.

Wholesale Energy Sales: Wholesale energy sales consist primarily of long-term sales contracts, opportunity sales of surplus system energy, and sales into the energy imbalance market in the western United States, and do not include derivative transactions. The table below presents Idaho Power’s wholesale energy sales for the three months ended March 31, 2025 and 2024 (in thousands, except for revenue per MWh amounts).

Previous wording

In the third quarter of 2024, wholesale energy revenues increased $1.9 million compared with the third quarter of 2023, as higher wholesale market prices more than offset a decrease in volumes sold. Wholesale energy revenues increased $15.3 million in the first nine months of 2024 compared with the same period of 2023, as higher wholesale energy sales volumes were partially offset by lower wholesale market prices. Wholesale energy prices were lower during the first nine months of 2024 compared with 2023 as more moderate winter and spring weather resulted in lower demand and lower power prices in the wholesale markets in the region. The financial impacts of fluctuations in wholesale energy sales are largely mitigated by Idaho Power's Idaho and Oregon power cost adjustment mechanisms, which are described below in this section of the MD&A under "Power Cost Adjustment Mechanisms."

Current wording

In the first quarter of 2025, wholesale energy revenues decreased $18.5 million compared with the same period of 2024, due primarily to lower wholesale market prices. Wholesale energy prices were lower during the first three months of 2025 compared with 2024 as more moderate winter weather resulted in lower power prices in the wholesale markets in the region. The financial impacts of fluctuations in wholesale energy sales are largely mitigated by Idaho Power's Idaho and Oregon power cost adjustment mechanisms, which are described below in this section of the MD&A under "Power Cost Adjustment Mechanisms."

Previous wording

The majority of the coal for Idaho Power’s jointly-owned plants is purchased through long-term contracts, including purchases from BCC, a one-third owned investment of IERCo. The price of coal from BCC is subject to fluctuations in mine operating expenses, geologic conditions, and production levels. BCC supplies the majority of the coal used by the Jim Bridger plant and BCC does not have significant sales to third parties. Natural gas is mainly purchased on the regional wholesale spot market at published index prices. In addition to commodity (variable) costs, both natural gas and coal expenses include costs that are more fixed in nature for items such as capacity charges, transportation, and fuel handling. Period to period variances in fuel expense per MWh are noticeably impacted by these fixed charges when generation output is substantially different between the periods.

Previous wording

Included in fuel expense are losses and gains on settled financial gas hedges entered into in accordance with Idaho Power's energy risk management policy. For the third quarters of 2024 and 2023, and the first nine months of 2024, losses on financial gas hedges of $18.4 million, $7.9 million, and $43.4 million, respectively, increased natural gas fuel expense, while in the first nine months of 2023 gains on financial gas hedges of $4.2 million reduced natural gas fuel expense. Most of these realized hedging losses and gains are passed on to customers through the power cost adjustment mechanisms described below.

Current wording

Included in fuel expense are losses and gains on settled financial gas hedges entered into in accordance with Idaho Power's energy risk management policy. For the first quarters of 2025 and 2024, losses on financial gas hedges of $12.2 million and $24.1 million, respectively, increased natural gas fuel expense.

Previous wording

The power supply accruals (deferrals) represent the portion of the power supply cost fluctuations accrued (deferred) under the power cost adjustment mechanisms. When actual power supply costs are lower than the amount forecasted in power cost adjustment rates, most of the difference is accrued as an increase to a regulatory liability or decrease to a regulatory asset. When actual power supply costs are higher than the amount forecasted in power cost adjustment rates, most of the difference is deferred as an increase to a regulatory asset or decrease to a regulatory liability. During the third quarter of 2024, higher purchased power and fuel costs led to higher actual power supply costs compared with the forecasted amount, which resulted in an increase in the amount of power supply costs deferred by the mechanism. During the first nine months of 2024, purchased power costs led to lower actual power supply costs compared with the forecasted amount, which resulted in an accrual of power supply costs by the mechanism. The amortization of the prior year’s balances represents the offset to the amounts being collected or refunded in the current power cost adjustment year that were deferred or accrued in the prior PCA year (the balancing adjustment component of the power cost adjustment mechanism).

◦in March 2024, as part of a competitive RFP process, Idaho Power entered into an energy and capacity market purchase agreement with an energy marketer for the right to acquire 200 MW on a daily basis during summer months beginning in 2026 for a term of at least five years;

Previous report — wording carried elsewhere

This benefit was due primarily to an overall increase in Idaho base rates, effective January 1, 2024, per the terms of the 2023 Settlement Stipulation. For more information on the 2023 Settlement Stipulation, see Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2023 Annual Report.

IDACORP's net income increased $21.4 million for the first nine months of 2024 compared with the first nine months of 2023, due primarily to higher net income at Idaho Power.

Previous report — wording carried elsewhere

Other changes in operating revenues and expenses, net, increased operating income by $21.8 million in the first nine months of 2024 compared with the first nine months of 2023, due partially to a decrease in net power supply expenses that were not deferred for future recovery in rates through Idaho Power's power cost adjustment mechanisms, which increased other changes in operating revenues and expenses, net, compared with the same period in 2023. More moderate wholesale natural gas and power market prices in the western United States and increased wholesale energy sales decreased Idaho Power's net power supply expenses in the first nine months of 2024 compared with the first nine months of 2023. The change was also partially due to the timing of recording and adjusting regulatory accruals and deferrals.

Previous report — wording carried elsewhere

The increase in income tax expense was primarily the result of higher income before income taxes, partially offset by an increase in additional ADITC amortization. Based on Idaho Power's current expectations of full-year 2024 results, Idaho Power recorded $22.5 million of additional ADITC amortization under its Idaho regulatory settlement stipulation during the first nine months of 2024, but recorded $7.5 million of additional ADITC amortization during the same period in 2023.

Previous report — wording carried elsewhere

Customer growth has contributed to increases in peak loads experienced in recent years. For example, Idaho Power's highest all-time winter peak demand of 2,719 MW occurred on January 16, 2024, and on July 22, 2024, Idaho Power reached a new all-time summer peak demand of 3,793 MW.
