TOPOCK
SubstationArizona · MOHAVE ELECTRIC COOPERATIVE
TOPOCK is an electric transmission substation in Arizona, operated by MOHAVE ELECTRIC COOPERATIVE. It is classified as high-voltage (230 kv) and connects 6 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.
