💧 Hydroelectric Power Plants in Arkansas
Arkansas operates 19 hydroelectric power plants totaling 1,351 MW of nameplate capacity. Annual generation: 3.3M 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.
