Middletown
BrownfieldMiddletown, Middlesex, Connecticut · Middletown Power LLC
Middletown is a oil plant in Middletown, Middlesex, Connecticut, retired 1998-10-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 69 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.
