List of largest power stations in the United States


This article lists the largest electrical generating stations in the United States in terms of current installed electrical capacity. Non-renewable power stations are those that run on coal, fuel oils, nuclear, natural gas, oil shale and peat, while renewable power stations run on fuel sources such as biomass, geothermal heat, hydro, solar energy, solar heat, tides, waves and the wind.
As of 2020 the largest power generating facility is the Grand Coulee Dam in Washington. The facility generates power by utilizing 27 Francis turbines and 6 pump-generators, totalling the installed capacity to 6,809 MW. The largest power generating facility under construction is the Chokecherry and Sierra Madre Wind Energy Project in Wyoming, which will generate 2,500-3,000 MW when completed in 2026.
