Xiaowan Hydropower Station located in the middle and lower reaches of the Lancangjiang River in Fengqing County and Nanrun County of Yunnan Province. With a thin double curved arch concrete dam, with a maximum height of 292m. CGGC has completed Chama highway, dam crest highway, external highway, excavation of dam abutment, and cable Crane platform of the Xiaowan Hydropower Station.
Electricity landmark projects - Xiaowan Hydropower Station on October 25, 04 one year ahead of schedule to achieve in damming the river. This marks the Xiaowan Hydropower Project has entered the 292 meters of concrete arch dam hyperbolic excavation and pouring the foundation stage. 

Nanjian County in the western junction with Fengqiangxian the Xiaowan Hydropower Station is planning steps Lancang River in the middle and lower reaches of the second level, power plants built 4.2 million kilowatt capacity, the generating capacity of 18.853 billion, according to the State Development Planning Commission and the request of the Government of Yunnan Province, in 2005 damming the river, by the end of 2010 the first generating unit. 

Xiaowan Hydropower Station on January 20, 2002 started, power plants will be built a capacity of the reservoir 14.914 billion cubic meters, and power generation based both flood control, irrigation, shipping, such as sediment and Comprehensive Utilization of the effectiveness of the Lancang River lower reaches of the "leading reservoir." Here Dam geological conditions favorable terrain, suitable for the construction of the high dam library, 292 meters long and the Xiaowan Hydropower Station, a multi-year regulating water resources, and is all the cascade hydropower stations in the middle and lower reaches of the highest one, by the concrete dam hyperbolic Gong dam, the dam toe plunge pool and two bars, the left bank of the right bank of a spillway and underground water power station components.
