Site description

Edgewater Generating Station is a coal-fired power station owned by Alliant Energy. It is located near Lake Michigan in Sheboygan, Wisconsin. The station began operating in 1931, and used to have five units with the combined capacity of 834 MW. Four units have been retired and only Unit 5 is operating at a capacity of 414 MW. Seven coal ash disposal areas near the station are regulated under the CCR rule. Four of them are surface impoundments located on site and the other three are landfills in the I-42 Ash Disposal Facility, located southwest of the station. You can find the industry-reported data here. For more information on the Edgewater Generating Station, see EIP’s 2019 National Coal Ash Report.
