19th largest plant in Kentucky · 1378th nationally
Kentucky Dam is a hydroelectric power plant in Kentucky with a nameplate capacity of 219 MW. It generates roughly 1.2M MWh per year — enough to power about 113,041 average U.S. homes.
Its capacity factor of 62% puts it in the middle range — running steadily but not full-time.

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.
