On October 30, the final inclined shaft—the No. 2 upper diversion inclined shaft—of the water diversion system at the State Grid Xinyuan Hebei Funing Pumped Storage Power Station was successfully expanded, marking the full completion of all inclined shafts in the system and a significant milestone in the project's construction.

The four inclined shafts of the water diversion system span a total length of 1,090 meters with a steep inclination angle of 55 degrees. The construction employed the challenging "directional drilling + raise boring" method for pilot shaft excavation, followed by manual drilling and blasting for expansion. Facing complex geological conditions, high technical difficulty, and elevated safety risks, the project teams established "Party Member Pioneer Teams" to optimize construction organization and refine blasting control. These efforts successfully addressed challenges such as fractured surrounding rock and large cross-section excavation under Class IV geological conditions, ensuring the safe and efficient completion of the inclined shafts.

The project team will continue to refine construction planning and enhance quality control throughout the process, striving to achieve the goal of connecting the first generating unit to the grid. This will contribute to regional energy structure optimization and green, low-carbon development.

The State Grid Xinyuan Hebei Funing Pumped Storage Power Station is a key project under China's 13th Five-Year Energy Plan. With a total installed capacity of 1.2 million kilowatts, the station will house four reversible pump-turbine units, each with a capacity of 300,000 kilowatts. The first unit is scheduled to commence operation in 2027, with full completion expected by 2028.
