en.Wedoany.com Reported - The first-layer excavation of the tailrace gate chamber at the Ruoqiang Pumped Storage Power Station was completed on June 8, marking the transition of the project's main works from the underground excavation phase to the structural construction phase.
This tailrace gate chamber is one of the three core caverns of the power station, responsible for functions such as tailrace water isolation, unit maintenance water sealing, and accident seepage prevention. The quality of its excavation directly impacts the long-term operational safety of the station.
Wang Fobao, head of the Ruoqiang Project Department of Sinohydro Bureau 5 Co., Ltd., stated that during the excavation of the tailrace gate chamber, key construction challenges such as blasting formation of large underground caverns and surrounding rock protection were primarily overcome. This efficiently advanced cavern excavation and support, creating conditions for subsequent layered excavation, anchoring, and lining construction.
The overall construction of the project is currently progressing in an orderly manner. For the lower reservoir works, dam foundation excavation and backfilling are underway. For the upper reservoir works, dam compaction tests and abutment excavation and backfilling are being carried out simultaneously. For the water conveyance and power generation system works, the first-layer excavation of the main and auxiliary powerhouse has been completed, and the main transformer chamber is scheduled to complete its first-layer construction by the end of June. The TBM tunneling progress for the water supply tunnel has reached 1,800 meters. The connecting road project between the upper and lower reservoirs is expected to be fully completed by October this year, which will then provide transportation support for the delivery of construction materials and equipment to the upper reservoir.
Chen Zhen, Manager of the Construction Management Department of CNNC Ruoqiang Pumped Storage Power Generation Co., Ltd., stated that over 2,000 construction personnel are currently stationed at the site, and all main works are progressing steadily. In the next steps, the project team will strictly adhere to safety and quality baselines, advancing all construction tasks with high standards and efficiency, striving for the early commissioning of the power station to fully support the transmission of electricity from southern Xinjiang and the integration of new energy.
The Ruoqiang Pumped Storage Power Station in Xinjiang, China, is invested in and constructed by CNNC Ruoqiang Pumped Storage Power Generation Co., Ltd., a subsidiary of China National Nuclear Corporation. It is a key implementation project under China's 14th Five-Year Plan. The project has a total installed capacity of 2,100 MW, with a total investment of 15.677 billion yuan. The construction period is 81 months. The first generating unit is expected to be connected to the grid for power generation in September 2030, and the station is scheduled to be fully completed and operational by December 2031.
Once completed and operational, the power station will serve the development of the southern Xinjiang power grid and the integration of new energy, undertaking tasks such as peak shaving, valley filling, energy storage, and frequency regulation for the power system. Its designed annual power generation capacity is 2.625 billion kWh. Operating at full load for six consecutive hours can meet the annual electricity demand of 1.3 million households. It is estimated to save approximately 1.345 million tons of standard coal annually and reduce carbon dioxide emissions by about 4.046 million tons per year, yielding significant ecological and social benefits. The implementation of this project will boost the development of the green energy industry in southern Xinjiang, assist the region in building a new-type power system, and contribute significantly to the achievement of the national "dual carbon" goals.
