Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, central China. The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012. The dam generates an average of 95±20 TWh (Terawatt hour) of electricity per year.

After the extensive monsoon rainfalls of 2020, the dam's annual production nearly reached 112 TWh. As well as producing electricity, the dam is intended to increase the Yangtze River's shipping capacity. By providing flood storage space, the dam reduces the potential for floods downstream which have historically plagued the Yangtze Plain. China regards the project as a monumental social and economical success,

With the design of state-of-the-art large turbines, and a move toward limiting greenhouse gas emissions. The dam has still caused ecological changes including an increased risk of landslides. Because of that, the dam has been controversial both domestically and abroad.

The power plant of 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 (Megawatt). 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.
