25 Largest Hydroelectric Power Plants In The World [2024]

Want to know the largest hydroelectric power plants in the world? In 2012, the report has it that the Three Gorges Dam, which is situated in the Chinese province of Hubei, became the world’s largest hydroelectric power station succeeding the Itaipu hydroelectric power station (Brazil/Paraguay).

As of the time this article was published the Three Gorges dam has an installed capacity of 22,500 megawatts (MW), compared to 14,000 MW for the Itaipu dam.

However, despite the great difference in installed capacity, the two plants generate very similar amounts of electricity per year: Itaipu 103 TWh (2016) and Three Gorges 111.8 TWh (2020). The reason is purely weather. 

The Three Gorges Dam experiences up to six months of the year in which there is very little water available to generate power, while the Paraná River that feeds Itaipu has much less seasonal variation in flow.

Both dams are two of only six in the world that exceeds 10,000 megawatts of installed capacity. The rest are: the Xiluodu Dam (13,860 MW), the Belo Monte Dam (11,233 MW), the Simón Bolívar Hydroelectric Power Plant (10,235 MW) and the Wudongde Dam (10,200 MW).
