ROCKINGHAM
SubstationNorth Carolina · DUKE ENERGY PROGRESS - (NC)
ROCKINGHAM is an electric transmission substation in North Carolina, operated by DUKE ENERGY PROGRESS - (NC). It is classified as high-voltage (230 kv) and connects 12 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.
