With the formal commissioning of the last unit on Sept 2, the main construction of the Datengxia Water Conservancy Project, which took nine years to finish, has been completed. The accompanying three-dimensional aquatic ecological protection system was also completed and is now operational.

Located in the Qianjiang River section of Guiping City, South China's Guangxi Zhuang Autonomous Region, the Datengxia water conservancy hydropower project began construction in 2014. It has a total storage capacity of 3.48 billion cubic meters and a flood control capacity of 1.5 billion cubic meters. It is one of 172 major water-saving and water supply projects in China and a crucial control project in the Pearl River Basin.
The technical specifications of the power generation units for the Datengxia water conservancy project, constructed by Power Construction Corporation of China (POWERCHINA), rank among the best in the country. The core components of the turbines were independently developed in China, with a thrust load of 3,800 tons. The runner diameter is 10.4 meters and the height is 7.5 meters. The generator stator core, made of iron, has an outer diameter of 17.2 meters, and the maximum diameter of the rotor is 16.4 meters.
To minimize the impact of project construction on the aquatic ecosystem in the basin, the Datengxia project also built a comprehensive fish life cycle management system, including the One Center (the Hongshui River rare fish conservation center), Double Fishways (the main dam fishway of Qianjiang River and Nanmu River natural-like ecological fishway), Double Breeding Stations (the Datengxia fish breeding station and the Laibin breeding station), and Five Artificial Habitats (four artificial fish nests and one artificial spawning ground).
The completion of this project will further enhance the flood control system in the Pearl River Basin, establish an important node in the national water network, and fully develop the "clean energy corridor" along the Hongshui River.
In addition, the project will contribute to governance and management in the Pearl River Basin, enhance the region's water security capabilities, promote high-quality local economic and social progress, and support the development of the Guangdong-Hong Kong-Macao Greater Bay Area.
