Joliet 29
BrownfieldJoliet, Will, Illinois · Midwest Generations EME LLC
Joliet 29 is a natural gas plant in Joliet, Will, Illinois, retired 2023-09-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 1,320 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.
