SOBRANTE
SubstationCalifornia · PACIFIC GAS & ELECTRIC COMPANY
SOBRANTE is an electric transmission substation in California, operated by PACIFIC GAS & ELECTRIC COMPANY. It is classified as high-voltage (230 kv) and connects 16 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.
