Subase Microgrid Project
BrownfieldGroton, New London, Connecticut · Connecticut Mun Elec Engy Coop
Subase Microgrid Project is a natural gas plant in Groton, New London, Connecticut. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 13 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.

Dataset updated . Screening estimates derived from public data sources.
Brownfield attributes are derived from EIA retired-generator and EPA public data. Existing capacity reflects the retired plant's historical nameplate, not deliverable interconnection for a new load. Confirm reusable interconnection rights, remediation status, and site availability with the utility, ISO, and current owner.
