GLEN CANYON
SubstationArizona · GARKANE ENERGY COOP, INC
GLEN CANYON is an electric transmission substation in Arizona, operated by GARKANE ENERGY COOP, INC. It is classified as high-voltage (345 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.
