Coffeen
BrownfieldCoffeen, Montgomery, Illinois · Illinois Power Generating Co
Coffeen is a coal plant in Coffeen, Montgomery, Illinois, retired 2019-11-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 1,005 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.
