HOWARD
SubstationOhio · OHIO POWER CO
HOWARD is an electric transmission substation in Ohio, operated by OHIO POWER CO. It is classified as sub-transmission (138 kv) and connects 8 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.
