Taconite Harbor Energy Center
BrownfieldSchroeder, Cook, Minnesota · ALLETE, Inc.
Taconite Harbor Energy Center is a coal plant in Schroeder, Cook, Minnesota, retired 2023-03-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 252 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.
