TAP135620
SubstationMinnesota · ALLETE, INC.
TAP135620 is an electric transmission substation in Minnesota, operated by ALLETE, INC.. It is classified as sub-transmission (115 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.
