Edgewater Generating Station
Encyclopedia
Edgewater Generating Station is a base load, coal
fired, electrical
power station
located in the city of Sheboygan
in Sheboygan County, Wisconsin. It provides electricity for customers in the northeastern part of Alliant Energy
's Wisconsin Power & Light service area, along with service to several local municipal utilities. In 2009, it was listed as the seventh largest generating station in Wisconsin, with a net summer capacity of 767 MW.
In 1952 one of the units was upgraded with a Babcock and 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
.
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 specifically built to serve the plant which branches off the main line three miles west of the plant.
Unit 3 and 4 share the same chimney
