ESSEX
SubstationNew York · PUBLIC SERVICE ELEC & GAS CO
ESSEX is an electric transmission substation in New York, operated by PUBLIC SERVICE ELEC & GAS CO. It is classified as high-voltage (230 kv) and connects 11 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.
