The Xiluodu Dam (simplified Chinese: 溪洛渡大坝; traditional Chinese: 溪洛渡大壩; pinyin: Xīluòdù Dàbà) is an arch dam on the Jinsha River, i.e. the upper course of the Yangtze in China. It is located near the town of Xiluodu in Yongshan County of Yunnan Province but the dam straddles into Leibo County of Sichuan Province on the opposite side of the river. The primary purpose of the dam is hydroelectric power generation and its power station has an installed capacity of 13,860 MW. Additionally, the dam provides for flood control, silt control and its regulated water releases are intended to improve navigation downstream. Construction on the dam and power station began in 2005 and the first generator was commissioned in 2013, the last in 2014. It is operated by China Yangtze Power and is currently the fourth-largest power station in the world, as well as the fifth tallest dam world-wide.[3][4]
