# List of power stations in Washington

Sources of Washington utility-scale electricity generation, full-year 2022:
This is a list of electricity-generating power stations in the U.S. state of Washington, sorted by type and name. These include facilities that are located in more than one state. In 2020, Washington had a total summer capacity of 30,669 MW through all of its power plants, and a net generation of 116,114 GWh. The electrical energy generation mix in 2022 was 67.6% hydroelectric, 12.5% natural gas, 8.4% nuclear, 6.9% wind, 3.1% coal, and 1.1% biomass which includes most refuse-derived fuel. Other gases and utility-scale solar facilities generated most of the remaining 0.4%. Small-scale photovoltaic installations generated an additional net 393 GWh to the state's electrical grid; an amount over four times larger than Washington's utility-scale photovoltaic plants.
Washington routinely delivers one-quarter of U.S. hydroelectric generation, and hosts the nation's largest capacity power station at Grand Coulee Dam. 60% of Washington households use electricity as their primary heating fuel, unlike most households in other U.S. states that typically utilize natural gas.
