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 2019, Arizona had a total summer capacity of 26,792 MW through all of its power plants, and a net generation of 113,552 GWh.[2] The corresponding electrical energy generation mix was 40.6% natural gas, 28.1% nuclear, 20.4% coal, 5.5% hydroelectric, 4.7% solar, 0.5% wind, and 0.2% biomass. Small-scale solar, including customer-owned photovoltaic panels, delivered an additional net 2,572 GWh to the state's electrical grid. This compares as about half the generation by Arizona's utility-scale photovoltaic plants.[1]

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 amount of electricity generated by utility-scale and small-scale solar together surpassed the amount from all of Arizona's hydroelectric facilities for the first time in 2017.[3]
