Tanner Street Generation
BrownfieldLowell, Middlesex, Massachusetts · BT Generation Holdings, LLC
Tanner Street Generation is a natural gas plant in Lowell, Middlesex, Massachusetts, retired 2024-10-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 151 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.
