Jack McDonough
BrownfieldSmyrna, Cobb, Georgia · Georgia Power Co
Jack McDonough is a coal plant in Smyrna, Cobb, Georgia, retired 2012-02-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 598 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.
