Quick Facts

  • The Grand Coulee Dam on Washington's Columbia River is the largest power plant by generation capacity in the United States, and the seventh-largest hydropower plant in the world. It typically supplies about 21 million megawatthours of electricity annually to eight western states and parts of Canada.
  • Washington generated more electricity from hydropower than any other state and accounted for 27% of the nation's total utility-scale hydroelectric generation in 2020.
  • Washington has the fifth-largest crude oil refining capacity in the nation and can process almost 652,000 barrels of crude oil per day at the state's five refineries. 
  • In 2020, Washington consumed less natural gas than half of the states, and in 2019, the state used less per capita than all but four other states and the District of Columbia. The largest share of the state's natural gas comes from Canada, either directly or through the state of Idaho.
