At a glance
FIVE FORKS is an electric transmission substation in Maryland, on DELMARVA POWER's transmission network. It is classified as sub-transmission (115 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.
