Marysville
BrownfieldMarysville, St Clair, Michigan · DTE Electric Company
Marysville is a coal plant in Marysville, St Clair, Michigan, retired 2011-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 200 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.
