PERRY
SubstationOhio · AMERICAN TRANSMISSION SYSTEMS, INC.
PERRY is an electric transmission substation in Ohio, operated by AMERICAN TRANSMISSION SYSTEMS, INC.. It is classified as high-voltage (345 kv) and connects 5 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.
