TAP155407
SubstationAlabama · GEORGIA POWER CO
TAP155407 is an electric transmission substation in Alabama, operated by GEORGIA POWER CO. It is classified as extra-high-voltage (500 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.
