This is a list of electricity-generating power stations in the U.S. state of Wyoming, sorted by type and name. In 2021, Wyoming had a total summer capacity of 10,096 MW through all of its power plants, and a net generation of 46,017 GWh in 2022. The corresponding electrical energy generation mix was 71.1% coal, 22.1% wind, 4.3% natural gas, 1.9% hydroelectric and 0.5% solar. Small-scale solar, which includes customer-owned photovoltaic panels, delivered 23 GWh to Wyoming's electrical grid.
Wyoming has the smallest population in the U.S., and in 2019 three-fifths of its electricity generation was sent to nearby western states. It contains more than one-third of the nation's recoverable coal reserves, accounted for two-fifths of all related U.S. mining activity, and exported much of its low-sulfur coal to power plants in 29 other states. Wyoming also mined and exported nearly all the uranium used to fuel the nation's fleet of nuclear power stations. These activities have declined somewhat in recent years, while extraction of Wyoming's oil and gas reserves continued to expand.

## Nuclear power stations

Wyoming has no utility-scale nuclear facilities. In June 2021, Terrapower and Pacificorp announced their intention to advance a novel reactor demonstration project at the site of a retiring coal plant in Wyoming. On 16 November 2021, Pacificorp announced the selection of the Naughton Power Plant in Kemmerer, Wyoming for the Natrium Demonstration Project.

The Chokecherry and Sierra Madre Wind Energy Project, with a planned capacity of up to 3,000 MW generated by about 1,000 turbines, is under construction in Carbon County and scheduled for completion in 2026. It would be the largest wind farm in the U.S. upon completion, and would serve the western U.S. market through planned new HVDC transmission capacity.
