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.[2] 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 (including refuse-derived fuel), and 0.2% other.[1]
Sources of Wisconsin utility-scale electricity generation in gigawatt-hours, full-year 2024:[1]
- Natural gas: 26,658 (40.7%)
- Coal: 20,816 (31.8%)
- Nuclear: 10,147 (15.5%)
- Solar: 2,939 (4.49%)
- Wind: 1,994 (3.04%)
- Hydroelectric: 1,905 (2.91%)
- Biomass: 943 (1.44%)
- Other: 107 (0.16%)
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[when?] to replace retiring facilities and satisfy rising demand.[9]
