TAP141227
SubstationOhio · DAYTON POWER & LIGHT CO
TAP141227 is an electric transmission substation in Ohio, operated by DAYTON POWER & LIGHT CO. It is classified as sub-transmission (138 kv) and connects 3 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.
