List of power stations in Arizona
Wikimedia list article
This is a list of electricity-generating power stations in the U.S. state of Arizona, sorted by type and name. In 2024, Arizona had a net summer capacity of 32.9 GW through all of its power plants, and a net generation of 116,027 GWh. The electrical energy generation mix in 2025 was 45% natural gas, 26.7% nuclear, 13.3% solar, 7.9% coal, 4.2% hydroelectric, 2.7% wind, and 0.2% biomass. Small-scale solar, including customer-owned photovoltaic panels, delivered an additional net 5,785 GWh to the state's electrical grid. This compares as about one-third the amount generated by Arizona's utility-scale solar plants.
Arizona's Palo Verde Nuclear Generating Station located to the west of Phoenix is the nation's largest facility by annual energy production, and is the second largest facility by power capacity after Washington state's Grand Coulee Dam hydroelectric station. The electricity generated by utility- and small-scale solar together surpassed the amount from all of Arizona's hydroelectric facilities for the first time in 2017.
