WISDOM
SubstationIowa · CITY OF MILFORD - (IA)
WISDOM is an electric transmission substation in Iowa, operated by CITY OF MILFORD - (IA). It is classified as sub-transmission (138 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.
