On September 5, 2024, it was reported that the dam filling of the upper reservoir of Shangyi Pumped Storage Power Station in Hebei Province has been completed, marking a new stage in the construction of the power station and taking a solid step towards the goal of water storage and the generation of the first unit.

The upper reservoir dam of Shangyi Pumped Storage Power Station is a concrete face rockfill dam with a maximum height of 115 meters, a crest width of 10 meters, a crest elevation of 1396 meters, a normal water level of 1392 meters, a total storage capacity of 11.13 million cubic meters, and a total filling volume of approximately 4.82 million cubic meters.

Under the careful planning and efficient execution of the Beijing Institute project department, during the dam filling construction period, the team not only committed to providing comprehensive technical services and support, but also raised on-site supervision to a new level, ensuring that the quality standards of every link are strictly in line. Faced with various problems arising during construction, the project department responded quickly, accurately assessed the situation, timely contributed professional insights and solutions, and effectively resolved potential quality hazards. The project department, with its profound professional foundation and keen insight, closely combined with the actual situation on site, scientifically optimized the excavation and support strategy of the dam foundation slope, accurately adjusted the slope ratio design of the dam body, and meticulously calibrated the key parameters of the dam materials. This series of measures significantly improved the construction efficiency and laid a solid foundation for the safety, stability, and high-quality completion of the upper reservoir dam.

The Shangyi Pumped Storage Power Station is located in Shangyi County, Zhangjiakou, Hebei Province, with a total installed capacity of 1400 megawatts. The power station will undertake tasks such as peak shaving, valley filling, frequency regulation, phase modulation, and emergency backup for the power grid. It plays an important strategic role in ensuring power supply to the capital, improving the reliability of the power system, promoting green energy transformation, and achieving the dual carbon goals.
