IDACORP, Inc. Announces Fourth Quarter and Year-End 2023 Results, Initiates 2024 Earnings Guidance

IDACORP, Inc. (NYSE: IDA) reported fourth quarter 2023 net income attributable to IDACORP of $31.3 million, or $0.61 per diluted share, compared with $42.1 million, or $0.83 per diluted share, in the fourth quarter of 2022. For the full year ended December 31, 2023, IDACORP reported net income attributable to IDACORP of $261.2 million, or $5.14 per diluted share, compared with $259.0 million, or $5.11 per diluted share, in 2022.

“During 2023, we continued to see the benefits of strong, sustained customer growth, as well as our commitment to operating efficiently, with our operations and maintenance expenses coming in flat compared to last year,” said IDACORP President and Chief Executive Officer Lisa Grow. “Partially offsetting those benefits were reductions in usage from mild weather, as well as higher depreciation and financing costs from the capital expenditures we are making to provide our growing customer base with reliable, affordable, and increasingly clean energy.”

“We filed our first general rate cases in over a decade in Idaho and Oregon in 2023, and we reached a constructive outcome in Idaho with new rates effective January 1 of this year, while the Oregon case is pending,” Grow added. “With necessary, thoughtful investments underway at unprecedented levels in our generation, transmission, and distribution resources, we could look to file another general rate case, or a limited issue rate proceeding, in Idaho as early as June of this year.”

IDACORP is initiating its full-year 2024 earnings guidance to the range of $5.25 to $5.45 per diluted share, with the expectation that Idaho Power will use between $35 and $60 million of additional tax credits available under the Idaho earnings support regulatory mechanism in 2024. Approximately $25 million of those additional tax credits relate to expected amortization of incremental tax credits generated from Idaho Power's investment in 2023 battery storage projects, as contemplated in the settlement stipulation for the Idaho general rate case (2023 Settlement Stipulation) approved by the Idaho Public Utilities Commission in December 2023. The earnings guidance also assumes normal weather conditions throughout the year.

Net Income - Fourth Quarter 2023

IDACORP's net income decreased $10.8 million for the fourth quarter of 2023 compared with the fourth quarter of 2022, due primarily to lower net income at Idaho Power.

At Idaho Power, customer growth increased operating income by $4.3 million in the fourth quarter of 2023 compared with the fourth quarter of 2022, as the number of Idaho Power customers grew by approximately 15,000, or 2.4 percent, during the year ended December 31, 2023. Lower sales volumes on a per-customer basis in all customer classes, but more significantly among residential customers, decreased operating income by $13.0 million. Milder weather in the fourth quarter of 2023, when compared with the fourth quarter of 2022, caused customers to use less energy on a per-customer basis for heating. The revenue impact of the decrease in sales volumes per customer was partially offset by the FCA mechanism (applicable to residential and small commercial customers), which increased revenues in the fourth quarter of 2023 by $8.8 million compared with the fourth quarter of 2022.

Transmission wheeling-related revenues decreased $4.2 million during the fourth quarter of 2023 compared with the fourth quarter of 2022, resulting primarily from a significant decrease in transmission line-loss settlement rates and associated revenues due to lower energy prices in the western United States.

Total other O&M expenses in the fourth quarter of 2023 were $8.8 million higher than in the fourth quarter of 2023, mostly due to the timing of performance-based variable compensation accruals, inflationary pressures on labor-related costs, higher professional service costs, and higher maintenance costs, including an increase in scheduled maintenance work at natural gas plants.

Depreciation expense increased $7.2 million in the fourth quarter of 2023 compared with the fourth quarter of 2022, due primarily to an increase in plant-in-service.

The $17.2 million decrease in Idaho Power income tax expense in fourth quarter of 2023 compared with fourth quarter of 2022 was primarily due to plant-related tax adjustments at Idaho Power. Based on Idaho Power's full-year 2023 results, Idaho Power reversed $7.5 million of additional ADITC amortization, resulting from its existing Idaho regulatory settlement stipulation, recorded during the first nine months of 2023. Idaho Power did not record any additional ADITC amortization in 2022.

Net Income - Full-Year 2023

IDACORP's net income increased $2.2 million for 2023 compared with 2022, due primarily to higher net income at Idaho Power.

Idaho Power's customer growth of 2.4 percent added $15.7 million to Idaho Power's operating income in 2023 compared with 2022. Lower sales volumes on a per-customer basis among all customer classes, but more significantly among residential and irrigation customers, decreased operating income by $31.3 million in 2023 compared with 2022. More moderate temperatures and greater precipitation in Idaho Power's service area during 2023, compared with 2022, led residential customers to use less energy per customer for cooling and heating and agricultural irrigation customers to use less energy per customer to operate irrigation pumps. The negative revenue impact of the decrease in sales volumes per residential and small commercial customer was partially offset by the FCA mechanism, which increased revenues in 2023 by $15.1 million compared with 2022.

The net increase in retail revenues per MWh, net of associated power supply costs and power cost adjustment mechanisms, increased operating income by $11.0 million in 2023 compared with 2022. The net increase in retail revenues per MWh was primarily due to the June 1, 2022, rate increase for Idaho Power’s Idaho retail customers related to an order from the Idaho Public Utilities Commission that authorized Idaho Power to accelerate the depreciation on and recover through 2030 the net book value of coal-related assets at Idaho Power's jointly-owned Jim Bridger plant, as of December 31, 2020, plus forecasted plant investments (Bridger Order).

Other O&M expenses were relatively flat in 2023 compared with 2022, as inflationary pressures on labor-related costs were mostly offset by lower expenses from scheduled cyclical plant maintenance projects, as well as the timing of regulatory deferrals and payment credits received related to a jointly-funded infrastructure project.

Depreciation expense increased $25.3 million due partially to an increase in plant-in-service. In addition, the increase was partially due to the impacts of the Bridger Order. The Bridger Order resulted in Idaho Power recording the deferral of certain depreciation expense in the second quarter of 2022, reducing depreciation expense in that year.

Non-operating expense, net, decreased $4.7 million in 2023 compared with 2022. Allowance for funds used during construction (AFUDC) increased as the average construction work in progress balance was higher throughout 2023 compared with 2022. Also, interest and investment income increased due to higher interest rates and higher average cash and cash equivalents balances. These increases were partially offset by higher interest expense on long-term debt and other liabilities in 2023 compared with 2022.

The $11.0 million decrease in Idaho Power income tax expense in 2023 compared with 2022 was primarily due to plant-related tax adjustments at Idaho Power.

The 2023 Settlement Stipulation removed the existing $25 million annual cap on the amount of accelerated amortization of ADITCs.

(4) Approximately $40 million of O&M expense relates to amortization of pension and wildfire mitigation plan regulatory assets, approved for recovery in the 2023 Settlement Stipulation effective January 1, 2024. The increased O&M expense is expected to be offset by collection through tariff-based retail revenues.
