💧 Hydroelectric Power Plants in New York

New York operates 169 hydroelectric power plants totaling 5,924 MW of nameplate capacity. Annual generation: 28.4M MWh.

Hydroelectric plants spin turbines using falling or flowing water — typically from a dam-impounded reservoir. They are dispatchable, long-lived, and emission-free at the point of generation, though large reservoirs can disrupt rivers and ecosystems and methane can be released from flooded vegetation.
