💧 Hydroelectric Power Plants in Pennsylvania

Pennsylvania operates 28 hydroelectric power plants totaling 2,429 MW of nameplate capacity. Annual generation: 2.7M 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.
