By the numbers
Wisconsin’s only nuclear power plant, the Point Beach Nuclear Plant, remains the biggest in the state by net generation, according to figures from the U.S. Energy Information Administration.
Point Beach, just north of Two Rivers, generated nearly 10.2 million megawatt-hours of electricity in 2025, enough to power nearly a million homes.
The next 10 largest plants by actual output rely on coal or natural gas. The predominantly coal-powered South Oak Creek and Elm Road plants, next to each other between Milwaukee and Racine, produced 9.48 million MWh. The natural gas-fueled Riverside and West Riverside Energy Center, adjacent plants between Janesville and Beloit, produced 7.67 million MWh.
The largest solar facility, Badger Hollow, west of Dodgeville, generated a total of 409,540 MWh, making it the 12th largest in output. As the Badger Institute has previously reported, natural gas and coal are the leading sources of electricity for Wisconsin. Even with just one plant remaining in operation, nuclear energy is the third largest source.
