The Kewaunee Power Station is a partially-decommissioned nuclear power plant, located on a 900 acres (360 ha) plot in the town of Carlton, Wisconsin, 27 miles (43 km) southeast of Green Bay, Wisconsin in Kewaunee County, and south of the city of Kewaunee.
KPS was the third nuclear power plant built in Wisconsin, and the 44th built in the United States. Due to falling electricity prices resulting from the falling price of natural gas, the plant ceased operation May 7, 2013.
On January 20, 2026 a Notice of Intent (NOI) was submitted by site owners EnergySolutions to the Nuclear Regulatory Commission (NRC) confirming their intent to submit an application for major licensing action for new nuclear generation at the Kewaunee site. This initiative was first announced in May 2025 and the application is expected to be submitted in 2028.
