WOODWARD SUBSTATION
SubstationArkansas · ENTERGY ARKANSAS INC
WOODWARD SUBSTATION is an electric transmission substation in Arkansas, operated by ENTERGY ARKANSAS INC. It is classified as high-voltage (230 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.
