ARAPAHOE
SubstationColorado · PUBLIC SERVICE CO OF COLORADO
ARAPAHOE is an electric transmission substation in Colorado, operated by PUBLIC SERVICE CO OF COLORADO. It is classified as high-voltage (230 kv) and connects 10 transmission lines. Substation proximity is one of the strongest speed-to-power signals for siting a datacenter — interconnection distance to an energized, high-voltage bus is often the binding constraint on time-to-energization.
