Unit 5 of the Zhentouba II hydropower station, one of CHN Energy’s hydropower stations on the Dadu River, was successfully connected to the grid for power generation on April 28. This marks the second generating unit to be brought online within two days, signifying that the project has achieved continuous and centralized grid connection of its units during the commissioning phase.
The completion of this milestone provides substantial momentum for optimizing the regional energy structure in southwest China’s Sichuan province and advancing low-carbon, high-quality development.
Zhentouba II hydropower station
The Zhentouba II hydropower station is the 22nd cascade station in the adjusted development plan for the main stream of the Dadu River, located in Jinkouhe District, Leshan City, Sichuan Province. As the first large-scale hydropower project to achieve grid connection during China’s 15th Five-Year Plan period (2026-2030), the station plays a fundamental role in the regional clean energy layout. The project has a total installed capacity of 300 MW and is equipped with six bulb tubular turbine-generator units, each with a capacity of 50 MW.
During the process of achieving continuous grid connection, the project team implemented systematic process management to overcome multiple technical challenges associated with grid integration. This ensured the stable operation of key equipment during testing and connection, enabling the successful realization of the milestone of centralized commissioning.
According to the plan, once fully completed and put into operation, the station is expected to generate approximately 1.503 billion kWh of electricity annually. The release of this capacity will effectively enhance the overall supply of clean energy in southwest China and provide reliable power support for Sichuan’s energy structure adjustment as well as the region’s green economic and social transformation.
