The article highlights the world’s ten largest hydroelectric dams, emphasizing their monumental engineering achievements and multifaceted roles in energy generation, flood control, and regional development. These dams represent decades of innovation and investment, showcasing how nations harness river systems to meet energy demands while addressing environmental and economic challenges. The list is ranked by installed hydroelectric capacity, illustrating the scale and impact of these megastructures. Leading the list is China’s Three Gorges Dam, the most powerful hydroelectric dam globally with a capacity of 22,500 MW. Completed in 2006 on the Yangtze River, it not only generates 84 terawatt-hours annually but also improves flood control and navigation, significantly boosting shipping capacity and reducing costs. China’s Baihetan Dam, completed in 2022 with 16,000 MW capacity, features the world’s most powerful single-unit turbines and plays a key role in reducing coal dependence and enhancing energy access in western provinces.
