HILLSBORO
SubstationTexas · ONCOR ELECTRIC DELIVERY CO.
HILLSBORO is an electric transmission substation in Texas, operated by ONCOR ELECTRIC DELIVERY CO.. It is classified as high-voltage (345 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.
