Palo Verde Generating Station

What Palo Verde Generating Station does

Palo Verde Generating Station is a three-unit, 4,200 megawatt pressurized water reactor nuclear power plant located in Tonopah, Arizona — the largest power generator in the western United States and one of the nation's largest clean-air energy producers. The station is jointly owned by Arizona Public Service (APS, the operating partner), Salt River Project, El Paso Electric, Southern California Edison, PNM, and Los Angeles Department of Water & Power, with electricity sold to these six utility co-owners under long-term power purchase agreements and ultimately distributed to approximately four million homes and businesses across Arizona, West Texas, New Mexico, and Southern California. The plant generates more than 32 million megawatt-hours of carbon-free baseload electricity annually and has been in commercial operation for over 40 years.

The station employs roughly 2,000 full-time workers (approximately one in three being veterans) and operates under an NRC nuclear license. Revenue mechanics are regulatory rather than market-based: as a regulated nuclear asset with a defined offtaker consortium, output is dispatched to the owner-utilities under long-term PPAs and pricing flows through their respective regulated rate structures rather than competitive wholesale markets. Beyond generation, Palo Verde operates supplementary programs in K-12 nuclear-science education, STEM workforce development with institutions including MIT, University of Arizona, ASU, and community colleges, and community partnership programs across Arizona.

In March 2026 APS filed a Subsequent License Renewal Application with the Nuclear Regulatory Commission seeking 20-year license extensions for all three units (targeting operations through 2065-2067), and the owners are collaborating with Tucson Electric Power and SRP to evaluate advanced nuclear technologies including small modular reactors as a potential future expansion at or near the site. Palo Verde contributes approximately $2.6 billion annually to Arizona's economy, pays nearly $56 million in annual property taxes as the state's largest single taxpayer, and spends roughly $201 million annually with 1,200 Arizona businesses.

Core offering

Palo Verde Generating Station is a three-unit pressurized water reactor nuclear power plant located in Tonopah, Arizona, producing 4,200 megawatts of carbon-free baseload electricity. The facility generates over 32 million megawatt-hours annually and sells that electricity under long-term power purchase agreements to its six co-owning utility partners for distribution to approximately 4 million homes and businesses across the Southwest United States.

Product overview

Palo Verde Generating Station is a nuclear power facility comprising three reactor units with a combined capacity of 4,200 megawatts, making it the largest power generator in the western United States. The station operates as the heart of Arizona Public Service's generation fleet, producing over 32 million megawatt-hours of clean, carbon-free electricity annually — enough to power more than 4 million homes across Arizona, West Texas, New Mexico, and Southern California. The facility has been operating for over 40 years. Beyond power generation, the station supports supplementary offerings including nuclear science educational resources (lesson plans, STEM outreach programs), community and industry partnerships (with organizations such as MIT, ASU, Nuclear Museum, and Nuclear Science Week), economic impact initiatives (with ~$2.6B annual contribution to Arizona's economy), and direct employment opportunities at the Tonopah facility. The site is jointly owned by APS, Salt River Project, Tucson Electric Power/El Paso Electric, Southern California Edison, PNM, and Los Angeles Department of Water & Power.
