First Unit of Jinchuan Hydropower Station Put into Grid-connected Power Generation

On May 12, the first unit of Jinchuan Hydropower Station, located on the Dadu River under China Energy Group, was put into grid-connected power generation, providing new support for the clean energy supply system in southwest China.

Situated in Jinchuan County, Aba Tibetan and Qiang Autonomous Prefecture, Sichuan Province, on the upper reaches of the Dadu River, Jinchuan Hydropower Station has a total installed capacity of 860,000 kilowatts, equipped with four mixed-flow water turbine generator units each with a single unit capacity of 215,000 kilowatts. With an annual power generation capacity of approximately 3.5 billion kilowatt-hours, it is listed as a key development project for energy construction supporting the economic and social development of Tibetan areas in Qinghai and other provinces.

This project plays a vital role in optimizing the power source structure of the regional power system and promoting the coordinated development of the economy, society and environment. As a clean and renewable energy project, it will effectively reduce carbon emissions and promote the green transformation of the energy structure in southwest China.

The Dadu River Basin is rich in hydropower resources, with 28 hydropower stations planned along its main stream and a total hydropower development capacity exceeding 27 million kilowatts. In addition to the grid-connected power generation of the first unit of Jinchuan Hydropower Station, a number of hydropower projects in the basin, including Zhentouba Phase II, Shaping Phase I and Chuosijia Hydropower Stations, have also achieved centralized grid-connected power generation within the year, with a total installed capacity of nearly 2 million kilowatts.

Zhentouba Phase II and Shaping Phase I Hydropower Stations, located in the lower reaches of the Dadu River, are key energy projects in Sichuan Province’s 14th Five-Year Plan, equipped with 12 units in total, and 4 units have recently been put into grid-connected power generation. Furthermore, Chuosijia Hydropower Station in the upper reaches of the Dadu River, with 4 units totaling 392,000 kilowatts, has been fully put into operation earlier this year.

Laoyingyan Phase II Hydropower Station in the middle reaches of the Dadu River achieved river closure on the eve of May Day, marking that the construction and development of hydropower energy has ushered in a peak at the start of the 15th Five-Year Plan. The concentrated grid connection and construction of these hydropower projects will further enhance the stability and sustainability of the clean energy supply in southwest China.
