Winsor Dam Power Station
BrownfieldWare, Hampshire, Massachusetts · Massachusetts Water Res Auth
Winsor Dam Power Station is a former hydro site in Ware, Hampshire, Massachusetts, retired 1991-12-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 1 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.
