NORTHFIELD
SubstationNew York · GREEN MOUNTAIN POWER CORP
NORTHFIELD is an electric transmission substation in New York, operated by GREEN MOUNTAIN POWER CORP. It is classified as high-voltage (345 kv) and connects 4 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.
