IBM Southbury
BrownfieldSouthbury, New Haven, Connecticut · Bloom Energy
IBM Southbury is a natural gas plant in Southbury, New Haven, Connecticut, retired 2023-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 1 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.
