METCALF 1
SubstationCalifornia · PACIFIC GAS & ELECTRIC COMPANY
METCALF 1 is an electric transmission substation in California, operated by PACIFIC GAS & ELECTRIC COMPANY. It is classified as extra-high-voltage (500 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.
