JOCASSEE SWITCHING STATION
SubstationTennessee · DUKE ENERGY CAROLINAS, LLC
JOCASSEE SWITCHING STATION is an electric transmission substation in Tennessee, operated by DUKE ENERGY CAROLINAS, LLC. It is classified as high-voltage (230 kv) and connects 4 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.
