SIBLEY
SubstationMissouri · KCP&L GREATER MISSOURI OPERATIONS CO.
SIBLEY is an electric transmission substation in Missouri, operated by KCP&L GREATER MISSOURI OPERATIONS CO.. It is classified as high-voltage (345 kv) and connects 10 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.
