Havana
BrownfieldHavana, Mason, Illinois · Dynegy Midwest Generation Inc
Havana is a coal plant in Havana, Mason, Illinois, retired 2019-11-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 718 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.
