10-K: Pinnacle West Capital Corporation Reports 2024 Results, Navigates Regulatory Landscape

Pinnacle West Capital Corporation's 2024 results reflect increased net income driven by new rates and customer growth, while the company addresses regulatory changes and clean energy initiatives.

Summary

• Pinnacle West Capital Corporation reported a consolidated net income attributable to common shareholders of $609 million for the year ended December 31, 2024, compared to $502 million in the prior year.
• The increase in net income was primarily due to new customer rates, increased customer usage and growth, the effects of weather, and higher Court Resolution Surcharge (CRS) and Lost Fixed Cost Recovery (LFCR) revenue.
• These positive factors were partially offset by higher operations and maintenance expense, higher depreciation and amortization expense, higher interest charges, higher income taxes, and lower transmission revenues.
• APS served approximately 1.4 million customers and owns or leases 6,540 MW of regulated generation capacity.
• The share of APS's energy supply derived from clean resources was approximately 54% in 2024, including nuclear, renewables, and demand-side management (DSM).
• APS is committed to providing 100% clean, carbon-free electricity by 2050 and plans to exit coal-fired generation by 2031.
• APS is pursuing participation in Southwest Power Pool (SPP) Markets+ and the Western Resource Adequacy Program to reduce customer costs and improve reliability.
• APS is working to establish and expand advanced grid technologies throughout its service territory to provide long-term benefits both to APS and its customers.
• APS is implementing strategies to attempt to reduce the risk of forecasting demands and the additional risk of these arrangements that could lead to stranded costs and other effects that could have material adverse impacts on APSs financial condition, results of operations, and cash flows.
