From October to the end of this year, CHN Energy will put five hydropower stations—Shuangjiangkou, Jinchuan, Zhentouba II, Shaping I and Chuosijia—into simultaneous operation along the Dadu River Basin. This major milestone will push Sichuan Province’s total installed hydropower capacity beyond 100 gigawatts (GW), marking a new stage in the Group’s clean energy development in the region.
CHN Energy has long regarded Sichuan as a strategic hub for its green and low-carbon transition. To date, the Group’s total installed power generation capacity in the province has reached 19.71 GW, accounting for 14.2% of Sichuan’s total capacity. Its annual power generation exceeds 88.3 billion kilowatt-hours, representing 16.7% of the province’s total electricity consumption, providing strong support for regional energy security.
The five hydropower stations set to begin operation demonstrate CHN Energy’s strong technical capabilities in hydropower construction. The Shuangjiangkou Hydropower Station features the world’s tallest gravel-core rockfill dam, with a maximum height of 315 meters. The Jinchuan Hydropower Station boasts Asia’s longest eco-simulated fishway, stretching 5.02 kilometers. Zhentouba II and Shaping I are the only large-scale hydropower projects during the 14th Five-Year Plan period to achieve full-process advancement. The Chuosijia Hydropower Station includes China’s longest headrace tunnel for power generation, measuring 21.185 kilometers.
Throughout construction, CHN Energy has applied a range of innovative technologies, including an automated dam core seepage control material transport system, 5G-enabled intelligent unmanned rolling machinery and a BIM full-lifecycle information model. The intelligent grouting technology used at Shuangjiangkou won the First Prize for Scientific and Technological Progress from the Chinese National Committee on Large Dams, while Jinchuan achieved full domestic development of BIM technical parameters, highlighting the Group’s industry-leading expertise in hydropower engineering.
Leveraging this milestone of five stations commissioned together, CHN Energy will accelerate the construction of an integrated clean energy base in the Dadu River Basin that combines hydropower, wind and solar resources. It aims to build a modern energy system featuring coordinated development of hydro, thermal, wind, solar, storage and hydrogen resources, contributing greater strength to the development of China’s new power system and the realization of national dual-carbon goals.
