TAP134506
SubstationMinnesota · OTTER TAIL POWER CO
TAP134506 is an electric transmission substation in Minnesota, operated by OTTER TAIL POWER CO. It is classified as high-voltage (230 kv) and connects 3 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.
