On May 4, the generator rotor of the first unit of CGN's Tuanfeng Weijiachong Pumped Storage Project — the first pumped storage project independently developed and constructed by CGN — was successfully hoisted, laying a solid foundation for the first unit to enter the final assembly sprint phase.

The generator rotor of this project has an outer diameter of 5.82 meters and a body height of 2.33 meters. After on-site assembly, the overall cylindricity was strictly controlled to within 0.22 mm, with eccentricity kept below 0.10 mm. The total weight, including the lifting tooling, reached 290 tonnes, making it the heaviest single component of the project. The rotor lifting operation required precise passage through a narrow gap of only 8 mm on each side, demanding high standards and stringent requirements for on-site precision work. Through meticulous planning and close coordination by the project company and all construction participants, the rotor was successfully positioned in place smoothly and accurately on the first attempt, without any collision or deviation.

The project is currently at the peak period of electromechanical equipment installation. The main installation work for the generator-motor, pump-turbine, spherical valve, and auxiliary systems is now in full swing across multiple fronts. The project company's management and staff remain on the front line, balancing project schedule management with safe production. They refine daily construction organization plans, closely monitor critical processes and key links, and ensure that the project progresses steadily and orderly.

As a major construction project planned under Hubei Province's Energy Development "14th Five-Year Plan," the project consists of an upper reservoir, a lower reservoir, and a water conveyance and power generation system. It has a total installed capacity of 298 MW, with 2 reversible pump-turbine generator units each of 149 MW capacity. The project is scheduled to achieve full-capacity commercial operation by 2026. It is of great significance for optimizing the regional energy mix, ensuring the safe and stable operation of the power grid, and promoting local economic and social development.
