MARENGO WIND PLANT
SubstationWashington · PACIFICORP
MARENGO WIND PLANT is an electric transmission substation in Washington, operated by PACIFICORP. It is classified as high-voltage (230 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.
