HERBERT A WAGNER
SubstationVirginia · BALTIMORE GAS & ELECTRIC CO
HERBERT A WAGNER is an electric transmission substation in Virginia, operated by BALTIMORE GAS & ELECTRIC CO. It is classified as high-voltage (230 kv) and connects 1 transmission line. 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.
