WHITE LAKE
SubstationNew Hampshire · PUBLIC SERVICE CO OF NH
WHITE LAKE is an electric transmission substation in New Hampshire, operated by PUBLIC SERVICE CO OF NH. It is classified as sub-transmission (115 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.
