The Three
Gorges Dam is a hydroelectric dam that spans the Yangtze
River by the town of Sandouping,
located in Yiling District, Yichang, Hubei province, China.
The
Three Gorges Dam is the world's largest power station in terms of installed capacity (22,500 MW). The dam is the largest operating
hydroelectric facility in terms of annual energy generation, generating 83.7
TWh in 2013 and 98.8 TWh in 2014, while the annual energy generation of the Itaipú Dam in Brazil and Paraguay was 98.6 TWh in 2013 and 87.8 in 2014.
Except for a ship
lift, the dam project was
completed and fully functional as of July 4, 2012, when the last of
the main water turbines in the underground plant began production.
Each main water turbine has a capacity of 700 MW. The dam body was completed
in 2006. Coupling the dam's 32 main turbines with two smaller generators
(50 MW each) to power the plant itself, the total electric generating
capacity of the dam is 22,500 MW.
As
well as producing electricity, the dam is intended to increase the Yangtze
River's shipping capacity and reduce the potential for floods downstream by
providing flood storage space. The Chinese government regards the project as a
historic engineering, social and economic success, with the design of state-of-the-art
large turbines and a move toward limiting greenhouse gas emissions.
However,
the dam flooded archaeological and cultural sites and displaced some
1.3 million people, and is causing significant ecological changes, including an increased risk of landslides. The dam has been a controversial topic
both domestically and abroad.
