North Main Street
BrownfieldNorwich, New London, Connecticut · City of Norwich - (CT)
North Main Street is a oil plant in Norwich, New London, Connecticut, retired 2023-05-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 19 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.
