Highland Ave. Landfill
BrownfieldSouth Portland, Maine
Highland Ave. Landfill is a former landfill site in South Portland, Maine. 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.
