EDGEWATER, a 770 MW Coal power plant in Sheboygan County, Wisconsin. Operated by WISCONSIN POWER & LIGHT CO, commissioned 1985.
How EDGEWATER compares
With 770 MW of capacity, EDGEWATER ranks 7th among the 141 operating power plants Bywatts maps in Wisconsin and 5th of the 15 operating Coal plants in the state. It accounts for about 12% of Wisconsin's operating Coal capacity and 4.8% of all operating capacity in the state. Nationally it is the 130th-largest of the 324 operating Coal plants in the database. Commissioned in 1985, it is newer than 63% of the 141 operating Wisconsin plants with a recorded commissioning year. Its operator, WISCONSIN POWER & LIGHT CO, runs 8 operating plants in Wisconsin totaling 3,001 MW. It shares Sheboygan County with one other operating plant, SHEBOYGAN FALLS.
EIA-860 lists 1 generator at the site with 414 MW of nameplate capacity, all conventional steam coal technology (this page's HIFLD capacity figure is 770 MW). Net generation was 2,092 GWh in 2024 (a 58% capacity factor), up 7% from 2022.

Weather peril exposure
EDGEWATER is a 770 MW coal power plant in Sheboygan County, WI, operated by WISCONSIN POWER & LIGHT CO, commissioned in 1985. Sheboygan County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.7 of 5 at the 67th national percentile. Hail is the leading peril, rated Relatively Moderate by FEMA at the 74th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a coal plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
