Castle Creek Hydroplant
BrownfieldAspen, Pitkin, Colorado · City of Aspen- (CO)
Castle Creek Hydroplant is a former hydro site in Aspen, Pitkin, Colorado. 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. Confirm reusable interconnection rights, remediation status, and site availability with the utility, ISO, and current owner.
