PASSYUNK
SubstationPennsylvania · PECO ENERGY CO
PASSYUNK is an electric transmission substation in Pennsylvania, operated by PECO ENERGY CO. It is classified as high-voltage (230 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.
