Wheaton
BrownfieldEau Claire, Chippewa, Wisconsin · Northern States Power Co - Minnesota
Wheaton is a oil plant in Eau Claire, Chippewa, Wisconsin, retired 2024-01-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 106 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.
