Sheepskin
BrownfieldEdgerton, Rock, Wisconsin · Wisconsin Power & Light Co
Sheepskin is a natural gas plant in Edgerton, Rock, Wisconsin, retired 2020-06-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 42 MW of generation, so the grid hookup, transmission rights, and often cooling-water access are already in place — collapsing the speed-to-power timeline versus a greenfield build.
