This is a list of electricity-generating power stations in the U.S. state of Wisconsin, sorted by type and name. In 2024, Wisconsin had a total summer capacity of 17.4 GW through all of its power plants, and a net generation of 65,276 GWh.[2] The electrical energy generation mix in 2025 was 35.6% natural gas, 35% coal, 15.3% nuclear, 6% solar, 3.3% hydroelectric, 2.9% wind, 1.8% biomass (including refuse-derived fuel), 0.1% petroleum, and less than 0.1% other.[1]
The Fox River powered the world's first commercial hydroelectric central power station, the Vulcan Street Plant, during 1882 to 1891.[3] An exact replica of the plant, designated as a National Historic Engineering Landmark, is located near the original site in Appleton.[4] Wisconsin also has the nation's oldest (since 1891) continuously operating hydroelectric facility, in Whiting, according to the U.S. Energy Information Administration.[5]
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,[6] and former Port Washington Power Plant.[7] Nuclear power has generated Wisconsin's largest share of carbon-free electrical energy since 1970.[8] Natural gas generation has nearly quadrupled over the past decade to replace retiring facilities and satisfy rising demand.[9]
