Shiras
BrownfieldMarquette, Marquette, Michigan · City of Marquette - (MI)
Shiras is a coal plant in Marquette, Marquette, Michigan, retired 2019-04-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 78 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.
