BROADWATER POWER PROJECT
SubstationMontana · NORTHWESTERN ENERGY LLC - (MT)
BROADWATER POWER PROJECT is an electric transmission substation in Montana, operated by NORTHWESTERN ENERGY LLC - (MT). It is classified as distribution (69–115 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.
