Colebrook Hydroelectric
BrownfieldColebrook, Litchfield, Connecticut · Metropolitan Dist of Hartford
Colebrook Hydroelectric is a former hydro site in Colebrook, Litchfield, Connecticut, retired 2019-05-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 3 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.
