Clay Boswell
BrownfieldCohasset, Itasca, Minnesota · ALLETE, Inc.
Clay Boswell is a coal plant in Cohasset, Itasca, Minnesota, retired 2018-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 150 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.
