💧 Hydroelectric Power Plants in Illinois
Illinois operates 10 hydroelectric power plants totaling 147 MW of nameplate capacity. Annual generation: 92.3k 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.
