This is a list of power stations in the U.S. state of California that are used for utility-scale electricity generation. This includes baseload, peaking, and energy storage power stations, but does not include large backup generators. As of 2018 [update] , California had 80 GW of installed generation capacity encompassing more than 1,500 power plants; with 41 GW of natural gas, 26.5 GW of renewable (12 GW solar, 6 GW wind), 12 GW large hydroelectric, and 2.4 GW nuclear.

In 2020, California had a total summer capacity of 78,055 MW through all of its power plants, and a net energy generation of 193,075 GWh. [3] Its electricity production was the third largest in the nation behind Texas and Florida. California ranks first in the nation as a producer of solar, geothermal, and biomass resources. [4] Utility-scale solar photovoltaic and thermal sources together generated 17% of electricity in 2021. Small-scale solar including customer-owned PV panels delivered an additional net 19,828 GWh to California's electrical grid, equal to about half the generation by the state's utility-scale facilities.

The Diablo Canyon Power Plant in San Luis Obispo County is the largest power station in California with a nameplate capacity of 2,256 MW and an annual generation of 18,214 GWh in 2018. [6] The largest under construction is the Westlands Solar Park in Kings County, which will generate 2,000 MW when completed in 2025. [7] [8]
