Company Description

Pinnacle West Capital Corporation (NYSE: PNW) is an energy holding company based in Phoenix, Arizona. According to company disclosures and recent news releases, it has consolidated assets measured in the tens of billions of dollars, approximately 6,500 megawatts of generating capacity and thousands of employees in Arizona and New Mexico. Its principal subsidiary is Arizona Public Service Company (APS), which provides retail electricity service to about 1.4 million homes and businesses in Arizona.

Core business and utility operations

Pinnacle West’s primary business is conducted through APS, a vertically integrated electric utility. APS serves customers in multiple Arizona counties and delivers electricity across a large service territory that includes the Phoenix metropolitan area. The company’s generating capacity is supported by a diverse fleet of resources, and APS describes its energy mix as including nuclear power from the Palo Verde Generating Station, natural gas, coal, solar, wind and energy storage resources.

APS reports that its energy portfolio is more than half supplied by clean resources, with clean energy accounting for about 54% of its total energy mix. Nuclear generation from Palo Verde is highlighted as a foundational, carbon-free resource that operates around the clock and supplies a significant portion of Arizona’s electricity. Coal and natural gas provide additional baseload and flexible capacity, while solar, wind and storage contribute to meeting demand and supporting clean energy objectives.

Nuclear and clean energy profile

Pinnacle West’s industry classification includes nuclear electric power generation, and APS holds an ownership interest in Palo Verde Generating Station, which is described in company communications as one of the nation’s largest energy producers. Palo Verde has been in operation for decades and has operating licenses extending into the mid-2040s. APS emphasizes Palo Verde’s role in supplying reliable, carbon-free energy and supporting a strong regional grid.

APS has stated an aspirational goal to be carbon-neutral by 2050. The company has also indicated that it is updating its clean energy goals from a zero-carbon framing to a carbon-neutral approach, with an emphasis on balancing reliability and affordability. Clean resources, including nuclear and renewables, are combined with dispatchable resources such as natural gas to meet customer needs during periods when solar and wind output is limited.

Service territory and demand growth

Through APS, Pinnacle West serves approximately 1.4 million residential and business customers in Arizona. APS reports serving customers in 11 of Arizona’s 15 counties and notes that its service area includes some of the fastest-growing regions in the United States. Company news releases describe robust customer growth and sales growth, driven in part by population increases, economic development and high summer temperatures that elevate electricity usage.

APS has reported multiple years of record peak demand, with new all-time peak loads set during recent summers. These records are attributed to strong customer growth and high temperatures. To address this growth, APS plans infrastructure investments and resource additions, including new generation projects and transmission and distribution upgrades, as outlined in company announcements.

Generation mix and planned investments

APS describes its energy portfolio as a balanced mix that includes:

  • Nuclear generation from Palo Verde Generating Station.
  • Natural gas plants that provide flexible, on-demand capacity, particularly during peak hours and extreme temperatures.
  • Coal resources that contribute baseload capacity, with some changes over time such as operations ceasing at certain plants like Cholla, as referenced in financial discussions.
  • Solar and wind resources that contribute renewable energy to the grid.
  • Energy storage resources that help integrate renewables and support reliability.

APS has discussed plans to add thousands of megawatts of new resources over a multi-year period to support Arizona’s rapid growth and maintain service during high-demand conditions. Company communications describe projects scheduled to come online in future years, including APS-owned resources and a proposed natural gas facility known as the Desert Sun Power Plant near Gila Bend, Arizona. This plant is described as a two-phase project intended to add up to 2,000 megawatts of reliable, flexible generation to the system, with a subscription model for extra-large energy users in one of the phases.

These include rate plan options, billing programs and financial assistance offerings for eligible customers. APS partners with numerous community organizations and nonprofits across Arizona to provide utility bill assistance, air conditioner repair and replacement, housing support and heat relief services, as described in company communications.

Strategic themes and risk considerations

  • Reliability and resiliency of the electric grid amid rapid customer and load growth.
  • Affordability for residential and business customers, including approaches such as having extra-large users fund certain infrastructure under a “growth pays for growth” model.
