PINNACLE WEST REPORTS 2024 FULL-YEAR AND FOURTH-QUARTER RESULTS
•New customer rates, retail sales growth of 5.7% and an exceptionally hot summer contribute to an increase in retail revenue and full-year financial results
•Annual retail customer growth increases a robust 2.1%
•Customer satisfaction continues improvement, reaches new highs
PHOENIX – Pinnacle West Capital Corp. (NYSE: PNW) today reported consolidated net income attributable to common shareholders of $608.8 million, or $5.24 per diluted share, for full-year 2024. This result compares with net income of $501.6 million, or $4.41 per diluted share, in 2023.
For the quarter ended Dec. 31, 2024, Pinnacle West reported a consolidated net loss attributable to common shareholders of $6.8 million, or a loss of $0.06 per diluted share, compared with a net loss of $23,000, or $0.00 per diluted share, for the same period in 2023.
The higher 2024 full-year results reflect an increase of about $107 million, primarily as a result of the impacts of new customer rates, increased customer usage and growth, the effects of weather, and higher revenue resulting from Arizona Public Service Co.’s (APS) Lost Fixed Cost Recovery (LFCR) adjustor mechanism and a surcharge resulting from the outcome of the utility’s 2019 Rate Case appeal. These positive factors were partially offset by higher operations and maintenance expense, higher depreciation and amortization expense mostly due to increased plant and intangible assets, higher interest charges, net of AFUDC, higher income taxes and lower transmission revenues.
“Our employees once again did an excellent job running and maintaining the electric grid and ensuring that our 1.4 million customers received the reliable electrical service they expect from us,”
said Pinnacle West Chairman, President and CEO Jeff Guldner. “Our strong year-end earnings not only reflect this outstanding operational performance, but the results are consistent with a fast-growing service territory and us making the substantial infrastructure investments needed to meet the energy requirements of all our customers, now and in the future.”
Reliability for a Growing State
Reliability remains at the core of the company’s customer service and drives plans to continue providing a balanced energy portfolio delivering power at reasonable rates.
“Our customer base, which for decades leaned heavily residential, is now more diversified than ever before,” APS President Ted Geisler said. “A dramatic increase in commercial and industrial customers in our service territory – including new semiconductor manufacturing plants and expanding data center operations – is leading to incredible economic growth and triggering a historic wave of demand for electricity in our state.”
APS, the company’s principal subsidiary, experienced customer growth of 2.1% in 2024 and anticipates projected average annual growth in the range of 1.5% to 2.5% through 2027. Not surprisingly, these changes are driving a significant increase in energy consumption. APS also experienced weather-normalized, year-over-year retail electricity sales growth of 5.7% in 2024. Future sales are expected to increase between 4% and 6% annually over the next three years due in large part to the expected additions of several large data centers and new large manufacturing facilities.
To prioritize reliability and meet requirements of this substantial growth, APS expects to add 9,805 megawatts (MW) of renewable power, battery storage and natural gas to the grid between 2025 and 2028 – more than 90% of which will be carbon-free. Some expansion highlights include:
•Power purchase agreements that are expected to add 3,321 MW of solar power along with 168 MW from the APS-owned Ironwood Solar Plant, currently under construction in Yuma County.
•At the Agave Solar Plant in Maricopa County, construction is under way on 150 MW of battery storage that will deliver solar energy to customers after sunset.
•Power purchase agreements for an anticipated 5,087 MW of battery energy storage that grid operators can release during evening hours when customer demand is greatest.
•500 MW of additional wind power in northern Arizona’s Navajo County; and
•Expansion of the company’s existing Sundance and Redhawk natural gas-fired power plants. These additions are expected to deliver a combined 487 MW, providing much-needed energy during peak consumption hours. Just as important, they provide a critical complement to the large quantities of solar and battery energy storage we’re adding to our system.
Additionally, excellent performance at the company’s generating facilities continues to benefit customers and the company’s bottom line. For the 16th consecutive year – and 20th overall – Palo Verde Generating Station's three nuclear units exceeded 30 million MWh of net generation and achieved a capacity factor of 93.7%. Importantly, the plant remains a cornerstone of APS’s aspirational goal to deliver 100% clean, carbon-free energy by 2050 and a nearer-term target to achieve a resource mix that is 65% clean by 2030.
“Our employees remain focused on creating value for customers and shareholders, including consistently working to minimize our costs, while maintaining reliable electric service and improving customer satisfaction. As a result, we are well-positioned to have a solid 2025,” Geisler concluded.
Staying Focused on Customer Satisfaction
In furtherance of a customer-centric culture, APS’s focus remains on its customers and the communities it serves. This past year, the company rolled out a newly designed customer bill with the aim of increasing personalization and helping customers better understand their energy use and find ways to save. The bill was developed with direct input from customers.
APS also increased its energy support and crisis bill assistance; maintained a summer moratorium on disconnects for past-due bills; assisted customers with payment arrangements; and partnered with more than 100 local non-profit and community agencies to connect the state’s most vulnerable populations with helpful resources.
These and other company-wide efforts helped provide a more frictionless customer experience that was recognized by APS customers, as measured by J.D. Power. For 2024, APS ranked at the top of the second quartile for large investor-owned utilities for both business and residential customers, with the residential results being APS’s highest rank and placement since 2016. In fact, this past year, residential customers ranked APS at or near the top of its peer set for Phone Customer Care, Power Quality & Reliability, Billing & Payment and Corporate Citizenship.
Financial Outlook
For 2025, the Company continues to estimate its consolidated earnings will be within a range of $4.40 to $4.60 per diluted share on a weather-normalized basis. Key factors and assumptions underlying this outlook can be found in the year-end/fourth-quarter 2024 earnings presentation slides at pinnaclewest.com/investors.
