GREENLAND GAP
SubstationWest Virginia · THE POTOMAC EDISON CO
GREENLAND GAP is an electric transmission substation in West Virginia, operated by THE POTOMAC EDISON CO. It is classified as extra-high-voltage (500 kv) and connects 3 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.
