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. , 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. 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. 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. The largest under construction is the Westlands Solar Park in Kings County, which will generate 2,000 MW when completed in 2025.

The California Independent System Operator (CAISO) oversees the operation of its member utilities.
