VOLNEY
SubstationNew York · NIAGARA MOHAWK POWER CORP.
VOLNEY is an electric transmission substation in New York, operated by NIAGARA MOHAWK POWER CORP.. 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.
