Powerhouse Six Array
BrownfieldOak Ridge, Tennessee
Powerhouse Six Array is a former superfund site in Oak Ridge, Tennessee. 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.

Dataset updated . Screening estimates derived from public data sources.
Brownfield attributes are derived from EIA retired-generator and EPA public data. Existing capacity reflects the retired plant's historical nameplate, not deliverable interconnection for a new load.
