Weston
BrownfieldRothschild, Marathon, Wisconsin · Wisconsin Public Service Corp
Weston is a natural gas plant in Rothschild, Marathon, Wisconsin, retired 2023-06-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 218 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.
