Legacy capacity

MW

Lockport Powerhouse is a former hydro site in Lockport, Will, Illinois, retired 1950-01-01. Retired generation sites are among the most attractive datacenter redevelopment targets: the existing interconnection was sized for roughly 16 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.

Why this site is datacenter-attractive: a former hydro site of this scale leaves behind a high-capacity grid interconnection that a new load can re-use, frequently shaving years off the interconnection queue. Retired-plant sites also tend to be already zoned for heavy industrial use with established road, rail, and water infrastructure.

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. Confirm reusable interconnection rights, remediation status, and site availability with the utility, ISO, and current owner.
