Three Gorges Dam calculated based on the average flow rate at the dam site, assuming the water level is 175 m and the plant gross efficiency is 90.15%. The actual power output in 2008 was obtained based on the monthly electricity sent to the grid. The Three Gorges Dam reached its design-maximum reservoir water level of for the first time on October 26, 2010, in which the intended annual power-generation capacity of 84.7 TWh was realized. In 2012, the dam's 32 generating units generated a record 98.1 TWh of electricity, which accounts for 14% of China's total hydro generation. The State Grid Corporation
Grand Inga Dam Grand Inga Dam The Grand Inga Dam is a proposed hydroelectric dam on the Congo River at Inga Falls in the Democratic Republic of the Congo. The proposed dam is the fourth and largest of the Inga dams, from Inga-I, from Inga-II, and from the proposed Inga-III. The dam has an expected generating capacity of , with 52 turbines each with a capacity of . This is close to twice the capacity of the Three Gorges Dam, which is currently known as the largest energy-generating body ever built. Inga Falls on the Congo River is a group of rapids (or
