MILLWOOD
SubstationNew York · CONSOLIDATED EDISON CO-NY INC
MILLWOOD is an electric transmission substation in New York, operated by CONSOLIDATED EDISON CO-NY INC. It is classified as high-voltage (345 kv) and connects 8 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.
