The top 20 largest Hydropower stations in the world.
This list is ranked according to the installed capacity of Hydropower stations. Because it is difficult to compare each Hydropower station’s specific scale, height, length, width, and volume cannot accurately reflect the Hydropower stations’ scale.
The installed capacity is a good ranking criterion because the larger the installed capacity, the larger the Hydropower stations’ scale.
The top 20 largest Hydropower stations are updated in real-time according to the installed capacity on this page. So this ranking changes dynamically.
If a new super Hydropower station is built, it will be automatically inserted into the list to keep the list correct.

4Belo Monte Dam
The Belo Monte Dam (formerly known as Kararaô) is a hydroelectric dam complex on the northern part of the Xingu River in the state of Pará, Brazil.
The installed capacity of the dam complex is 11,233 megawatts (MW), Considering the oscillations of flow river, guaranteed minimum capacity generation from the Belo Monte Dam would measure 4,571 MW, 39% of its maximum capacity.
The Belo Monte Dam would be 90 metres (300 ft) tall and 3,545 metres (11,631 ft) long and have a structural volume (embankments included) of 25,356,000 cubic metres (895,400,000 cu ft) . the Bella Vista would be 33 metres (108 ft) high and 351 metres (1,152 ft) long and have a structural volume of 239,500 cubic metres (8,460,000 cu ft).
It total cost about US$18.5 billion (estimated).

3Xiluodu Dam
Xiluodu Hydropower Station is located in China. The section of Jinsha River Canyon between Leibo County, Sichuan Province and Yongshan County, Yunnan Province.
It is a typical “3 high 3 large” hydropower station. “Three highs” means high dam (300m level), high seismic intensity (basic intensity Ⅷ degree), high-speed water flow (close to 50m / s); “three highs” means large flow (maximum discharge is about 50000m³ / s), large underground Workshop (top arch span over 30m), large unit (single unit capacity 770MW).
It total cost about US $12.2 billion ( ¥79.2 billion yuan).

2Itaipu Dam
The Itaipu Dam was built by Brazil and Paraguay on the Parana River. It is located in the river section between the border of Brazil and Paraguay,Construction began In January 1975.
The total length of the dam is 7,235 metres (23,737 ft). The crest elevation is 225 metres (738 ft), The dam is 196 metres (643 ft) high, equivalent to a 65-story building.It consumed 12.3 million cubic meters of concrete, while the iron and steel employed would permit the construction of 380 Eiffel Towers.
The maximum flow of Itaipu’s fourteen segmented spillways is 62.2 thousand cubic metres per second (2.20×106 cu ft/s), into three skislope formed canals. It is equivalent to 40 times the average flow of the nearby natural Iguaçu Falls.
It total cost about US $19.6 billion.
