M L Hibbard
BrownfieldDuluth, St Louis, Minnesota · ALLETE, Inc.
M L Hibbard is a oil plant in Duluth, St Louis, Minnesota, retired 2003-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 50 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.
