G G ALLEN
SubstationNorth Carolina · DUKE ENERGY CAROLINAS, LLC
G G ALLEN is an electric transmission substation in North Carolina, operated by DUKE ENERGY CAROLINAS, LLC. It is classified as distribution (69–115 kv) and connects 14 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.
