BELFIELD
SubstationNorth Dakota · WAPA-- WESTERN AREA POWER ADMINISTRATION
BELFIELD is an electric transmission substation in North Dakota, operated by WAPA-- WESTERN AREA POWER ADMINISTRATION. It is classified as high-voltage (345 kv) and connects 5 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.
