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 2023, Washington had a total summer capacity of 30,884 MW through all of its power plants, and a net generation of 102,960 GWh.{{cite web |url=http://www.eia.gov/electricity/state/washington/ |title=Washington Electricity Profile |publisher=U.S. Energy Information Administration |accessdate=2025-04-13}} The electrical energy generation mix in 2024 was 59.6% hydroelectric, 17.7% natural gas, 9.8% nuclear, 8.3% wind, 2.8% coal, 1.1% biomass which includes most refuse-derived fuel. Utility-scale solar and other gases generated most of the remaining 0.7%. Small-scale photovoltaic installations generated an additional net 643 GWh to the state's electrical grid; an amount nearly 50 percent 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.{{cite web |url=https://www.eia.gov/state/analysis.php?sid=WA |title=Washington Electricity Profile Analysis |publisher=U.S. EIA |accessdate=January 15, 2021}}
