BrownfieldOglesby, LaSalle, Illinois · Dynegy Midwest Generation Inc
Oglesby is a natural gas plant in Oglesby, LaSalle, Illinois, retired 2013-01-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 70 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.
