Twin Falls (MI)
BrownfieldIron Mountain, Dickinson, Michigan · Wisconsin Electric Power Co
Twin Falls (MI) is a former hydro site in Iron Mountain, Dickinson, Michigan, retired 2016-07-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 6 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.
