RISER304227

Substation

Arizona

Max voltage
69
kV

RISER304227 is an electric transmission substation in Arizona. 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.
