en.Wedoany.com Reported - On June 20, the Dadu River Jinchuan Hydropower Station, designed and constructed by PowerChina, commenced full-capacity power generation, adding new support to the clean energy supply system in Southwest China. This is of great significance for optimizing China's energy structure and promoting coordinated economic and social development.

Jinchuan Hydropower Station is the 6th cascade in the planned 28-step development of the mainstream Dadu River. Located in the upper reaches of the Dadu River within Jinchuan County, Aba Tibetan and Qiang Autonomous Prefecture, Sichuan Province, it has a total installed capacity of 860 MW, equipped with four 215 MW Francis turbine-generator units, generating approximately 3.5 billion kWh annually. The station was surveyed and designed by PowerChina Northwest Engineering Corporation Limited, supervised by PowerChina Guiyang Engineering Corporation Limited, and constructed by Sinohydro Bureau 7 Co., Ltd. and Sinohydro Bureau 10 Co., Ltd.

The station's key structures mainly include a concrete face rockfill dam, a water diversion and power generation system, and an underground powerhouse. The dam has a maximum height of 112 meters, making it a rare 100-meter-class concrete face rockfill dam in China built on a deep overburden layer with a maximum depth of 65 meters.

During construction, facing complex geological conditions with deep overburden and alternating soft and hard rock layers, as well as numerous world-class technical challenges, the PowerChina project team, together with all participating parties, overcame these through nearly two decades of scientific and technological research. They set multiple "engineering bests" in China's hydropower construction in fields such as engineering technology, ecological and environmental protection, and digital construction.

The construction of the station holds significant importance and value for optimizing the power supply structure of Sichuan's power system, enhancing the stability of regional power supply, improving the ecological environment quality of the river basin, and promoting high-quality economic and social development in the Sichuan-Tibet region.
