List of power stations in Arizona
This is a list of electricity-generating power stations in the U.S. state of Arizona, sorted by type and name. In 2023, Arizona had a net summer capacity of 29,885 MW through all of its power plants, and a net generation of 111,838 GWh. The electrical energy generation mix in 2024 was 47.5% natural gas, 27.9% nuclear, 9.3% solar, 8.5% coal, 4.6% hydroelectric, 2.2% wind, and 0.2% biomass. Small-scale solar, including customer-owned photovoltaic panels, delivered an additional net 5,450 GWh to the state's electrical grid. This compares as about one-half 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.
