Itaipu Dam
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. It has a combined generating capacity of 22.5 gigawatts and a designed annual generation capacity of 88.2 billion kilowatt hours. 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. Between 2010 (first design-maximum reservoir water level) and 2019, the dam generated an average of 92 TWh of electricity per year, just second to Itaipu dam average of 92.8 TWh of electricity per year during the same period. Due to extensive monsoon of 2020 year with heavy rainfalls, the annual production reached ~112 TWh that year, which broke the previous world record of annual production by Itaipu Dam equal to ~103 TWh of 2016 year.
