COMANCHE
SubstationColorado · BLACK HILLS/COLORADO ELEC.UTIL
COMANCHE is an electric transmission substation in Colorado, operated by BLACK HILLS/COLORADO ELEC.UTIL. It is classified as high-voltage (345 kv) and connects 11 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.
