TAP204301
SubstationWyoming · POWDER RIVER ENERGY CORPORATION
TAP204301 is an electric transmission substation in Wyoming, operated by POWDER RIVER ENERGY CORPORATION. It is classified as sub-transmission (115 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.
