Edgewater Generating Station is a 380 megawatt (MW) coal power plant located in Sheboygan, Wisconsin. It provides electricity for customers in the northeastern part of Alliant Energy's Wisconsin Power & Light service area and service to several local municipal utilities. In 2009, it was the seventh largest generating station in Wisconsin, with a net summer capacity of 767 MW.[1]

In 1952 one of the units was upgraded with a Babcock & Wilcox cyclone boiler. At the time, the facility was using a 50/50 mix of Illinois and West Virginia coal. The West Virginia coal was shipped via lake freighter from Lorain, Ohio.[6]

At present, coal is delivered to the plant entirely by railroad, originating primarily from the Powder River Basin in Wyoming, via a Union Pacific spur line that was originally the main line of the Milwaukee Northern interurban railway.

Unit 3 and 4 share the same chimney.

Unit 3 turbine and generator were manufactured by Allis-Chalmers. Unit 4 was manufactured by General Electric, with an Alterrex excitation system. Unit 5 was also manufactured by General Electric, with a Generrex excitation system.[citation needed]

Retirement and decommissioning[]

Unit 3 was retired at the end of 2015 due to its age and efficiency.[4] Unit 4 was retired in 2018 as Alliant Energy worked to reduce 80 percent of carbon dioxide emissions by 2050. Unit 4's electricity generation would be replaced by Riverside Energy Center in the Town of Beloit, which uses natural gas.[5]

On May 22, 2020, Alliant Energy announced that the plant would be decommissioned by the end of 2022, and the property would be redeveloped for another use; Unit 5's generating capacity has also been replaced by a further expansion of Riverside.[7]
