Highland
BrownfieldHighland, Madison, Illinois · City of Highland
Highland is a oil plant in Highland, Madison, Illinois, retired 2023-03-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 4 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.
