AGAWAM
SubstationNew York · CONNECTICUT LIGHT & POWER CO
AGAWAM is an electric transmission substation in New York, operated by CONNECTICUT LIGHT & POWER CO. It is classified as high-voltage (345 kv) and connects 10 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.
