Dallman
BrownfieldSpringfield, Sangamon, Illinois · City of Springfield - (IL)
Dallman is a coal plant in Springfield, Sangamon, Illinois, retired 2024-03-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 388 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.
