ARROWHEAD
SubstationNorth Dakota · ALLETE, INC.
ARROWHEAD is an electric transmission substation in North Dakota, operated by ALLETE, INC.. It is classified as high-voltage (230 kv) and connects 1 transmission line. 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.
