TAP203939
SubstationColorado · SOUTHEAST COLORADO POWER ASSN
TAP203939 is an electric transmission substation in Colorado, operated by SOUTHEAST COLORADO POWER ASSN. It is classified as sub-transmission (115 kv) and connects 3 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.
