AFTON
SubstationNew Mexico · EL PASO ELECTRIC POWER COMPANY
AFTON is an electric transmission substation in New Mexico, operated by EL PASO ELECTRIC POWER COMPANY. It is classified as high-voltage (345 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.
