List of power stations in Wisconsin
This is a list of electricity-generating power stations in the U.S. state of Wisconsin, sorted by type and name. In 2023, Wisconsin had a total summer capacity of 17,580 MW through all of its power plants, and a net generation of 62,548 GWh. The electrical energy generation mix in 2024 was 40.7% natural gas, 31.8% coal, 15.5% nuclear, 4.5% solar, 3% wind, 2.9% hydroelectric, 1.4% biomass, and 0.2% other.
The Fox River powered the world's first commercial hydroelectric central power station, the Vulcan Street Plant, during 1882 to 1891. An exact replica of the plant, designated as a National Historic Engineering Landmark, is located near the original site in Appleton. Wisconsin also has the nation's oldest continuously operating hydroelectric facility, in Whiting, according to the U.S. Energy Information Administration.
During the first half of the 20th century, Wisconsin's utility companies pioneered efficiency improvements for coal-fired electricity generation at the former East Wells (Onieda) Street Power Plant, and former Port Washington Power Plant. Nuclear power has generated Wisconsin's largest share of carbon-free electrical energy since 1970. Natural gas generation has nearly quadrupled over the past decade to replace retiring facilities and satisfy rising demand.
