GAVIN
SubstationOhio · AMERICAN ELECTRIC POWER CO., INC
GAVIN is an electric transmission substation in Ohio, operated by AMERICAN ELECTRIC POWER CO., INC. It is classified as extra-high-voltage (765 kv+) and connects 10 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.
