BrownfieldWillmar, Kandiyohi, Minnesota · Willmar Municipal Utilities
Willmar is a natural gas plant in Willmar, Kandiyohi, Minnesota, retired 2020-07-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 30 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.
