Pfizer Groton Plant
BrownfieldGroton, New London, Connecticut · Pfizer Inc
Pfizer Groton Plant is a natural gas plant in Groton, New London, Connecticut, retired 2015-06-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 5 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.
