List of power stations in Wyoming

This is a list of electricity-generating power stations in the U.S. state of Wyoming, sorted by type and name. In 2019, Wyoming had a total summer capacity of 8,667 MW through all of its power plants, and a net generation of 42,146 GWh.[2] The corresponding electrical energy generation mix was 83.9% coal, 9.9% wind, 3.4% natural gas (including up to 0.9% other petroleum gases and 0.1% petroleum liquids), 2.4% hydroelectric and 0.4% solar. Small-scale solar which includes customer-owned photovoltaic panels delivered in additional net 9 GWh to Wyoming's electrical grid. This compares as one-twentieth the amount generated by the state's first utility-scale solar PV facility which entered into service the prior year.[1]

Sources of Wyoming electricity generation: full-year 2019 [1]

  Coal (83.9%)

  Natural Gas (3.4%)

  Hydroelectric (2.4%)

  Wind (9.9%)

  Solar (0.4%)

Wyoming had the smallest population in the U.S. in 2019, and 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.[3]
