ETNA
SubstationNew York · NEW YORK STATE ELEC & GAS CORP
ETNA is an electric transmission substation in New York, operated by NEW YORK STATE ELEC & GAS CORP. It is classified as sub-transmission (115 kv) and connects 8 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.
