 The Three Gorges Dam in Hubei, China, has the world's largest instantaneous generating capacity (22,500 MW), with the Itaipu Dam in Brazil/Paraguay in second place (14,000 MW).Despite the large difference in installed capacity these two power stations generate nearly equal amounts of electrical energy during the course of an entire year - Itaipu 97.1 TWh in 2016 and Three Gorges 98.8 TWh in 2014, because the Three Gorges experiences six months per year when there is very little water available to generate power, while the Paraná River that feeds the Itaipu has a much lower seasonal variance in flow.Energy output of the Three Gorges reaches 125 TWh in years of high feed availability.
