SubstationArizona · ARIZONA PUBLIC SERVICE COMPANY
GILA RIVER is an electric transmission substation in Arizona, operated by ARIZONA PUBLIC SERVICE COMPANY. It is classified as extra-high-voltage (500 kv) and connects 7 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.
