FRANKS
SubstationIllinois · UNION ELECTRIC CO - (MO)
FRANKS is an electric transmission substation in Illinois, operated by UNION ELECTRIC CO - (MO). It is classified as high-voltage (345 kv) and connects 1 transmission line. 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.
