ENNIS
SubstationColorado · WAPA-- WESTERN AREA POWER ADMINISTRATION
ENNIS is an electric transmission substation in Colorado, operated by WAPA-- WESTERN AREA POWER ADMINISTRATION. It is classified as sub-transmission (115 kv) and connects 1 transmission line. 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.
