BIG SHANTY
SubstationGeorgia · GEORGIA POWER CO
BIG SHANTY is an electric transmission substation in Georgia, operated by GEORGIA POWER CO. It is classified as extra-high-voltage (500 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.
