The Xiaowan Dam (simplified Chinese: 小湾坝; traditional Chinese: 小灣壩; pinyin: Xiǎowān Bà) is an arch dam on the Lancang (Mekong) River in Nanjian County, Yunnan Province in southwest China. The primary purpose of the dam is hydroelectric power generation and it supports a 4,200 MW power station. Constructed between 2002 and 2010 by Huaneng Power International at a cost of ¥32 billion (nearly US$3.9 billion), it is the world's second highest arch dam at 292 m (958 ft). It is also third highest among dams of all types behind Jinping-I and Nurek and the third largest hydroelectric power station in China.[3][4][5][6]
