MAUPIN
SubstationOregon · BONNEVILLE POWER ADMINISTRATION
MAUPIN is an electric transmission substation in Oregon, operated by BONNEVILLE POWER ADMINISTRATION. It is classified as high-voltage (230 kv) and connects 3 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.
