HENRY COUNTY
SubstationIndiana · DUKE ENERGY INDIANA, LLC
HENRY COUNTY is an electric transmission substation in Indiana, operated by DUKE ENERGY INDIANA, LLC. It is classified as sub-transmission (138 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.
