MILL CREEK STATION
SubstationIndiana · LOUISVILLE GAS & ELECTRIC CO
MILL CREEK STATION is an electric transmission substation in Indiana, operated by LOUISVILLE GAS & ELECTRIC CO. It is classified as high-voltage (345 kv) and connects 6 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.
