Deer Island Treatment Plant
BrownfieldWinthrop, Suffolk, Massachusetts · Massachusetts Wtr Rauth-Deer I
Deer Island Treatment Plant is a former biomass site in Winthrop, Suffolk, Massachusetts, retired 2004-03-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 12 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.
