OREANA
SubstationNevada · SIERRA PACIFIC POWER COMPANY
OREANA is an electric transmission substation in Nevada, operated by SIERRA PACIFIC POWER COMPANY. It is classified as sub-transmission (115 kv) and connects 2 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.
