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. [4] On 16 November 2021, Pacificorp announced the selection of the Naughton Power Plant in Kemmerer, Wyoming, for the Natrium Demonstration Project. [5]

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. [51] 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. [52]

Battery storage facilities

Wyoming had no utility-scale battery storage facilities in 2019.
