List of power stations in Washington
From Wikipedia, the free encyclopedia
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.[2] 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.[1]
Sources of Washington utility-scale electricity generation in gigawatt-hours, full-year 2024:[1]
- Hydroelectric: 60,458 (59.6%)
- Natural gas: 17,959 (17.7%)
- Nuclear: 9,967 (9.82%)
- Wind: 8,421 (8.30%)
- Coal: 2,847 (2.80%)
- Biomass: 1,121 (1.10%)
- Solar: 436 (0.43%)
- Other gases: 223 (0.22%)
- Other: 75 (0.07%)
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.[3]
