Rush Island
BrownfieldFestus, Jefferson, Missouri · Union Electric Co - (MO)
Rush Island is a coal plant in Festus, Jefferson, Missouri, retired 2024-10-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 1,242 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.
