Port Jefferson
BrownfieldPort Jefferson, Suffolk, New York · National Grid Generation LLC
Port Jefferson is a oil plant in Port Jefferson, Suffolk, New York, retired 1997-09-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 92 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.
