Xiaowan Dam, Hydroelectric power station in Nanjian County, Yunnan Province, China
The Xiaowan Dam extends 902 meters across the Lancang River, incorporating six Francis turbines that generate 4,200 megawatts of electrical power.
Construction of this massive infrastructure project began in 2002 and required eight years to complete, with the final generator becoming operational in August 2010.
The construction of Xiaowan Dam led to the relocation of 32,737 residents from the surrounding areas, transforming local communities and their traditional way of life.
The dam contains two spillways with discharge gates that can release up to 20,709 cubic meters of water per second during flood conditions.
This concrete arch dam stands at 292 meters tall, making it the second highest structure of its type in the world with a base width of 69 meters.
