BJEC is the first investigation design enterprise engaged in the study of technology of pumped storage power stations. Since 1970s, based on the development trends of high head and large capacity for pumped storage power stations globally, research on relevant technology has been carried out. The scientific achievements played an important role in the development of design technology and construction of project for pumped storage power stations in China. Considering the power system features and distribution of water resources, the planning of site selection for pumped storage power stations is progressing gradually, including Hebei (including Beijing and Tianjin), Shanxi, Inner Mongolia, Jilin, Liaoning, Heilongjiang, Shandong, Jiangsu, Anhui, Guangdong, etc. The investigation and design of more than 20 large-sized pumped storage power stations have been carried out, including Shisanling, Langya Mountain, Zhanghewan, Xilongchi, Hohhot, Dunhua, Fengning, Yimeng, Wendeng, etc. Among them, pumped storage power stations in Ming Tombs (Beijing), Langya Mountain (Anhui), Zhangjiawan (Hebei), Xilongchi (Shanxi) ,Hohhot (Inner Mongolia) and Dunhua (Jilin) were put into operation in 1997, 2006, 2008, 2012, 2014 and 2021 successively.

After years of practice, BJEC has developed a set of core technology of investigation and design for pumped storage power projects and mastered a series of key technologies, such as the theories and methods of the demand analysis and planning arrangement for pumped storage in complex power system, the design of whole reservoir seepage control with bituminous concrete and reinforced concrete, the technology of reservoir basin seepage control in karst area, the theories and methods of structural design for penstocks with extra high head & high PD value and underground crescent-rib reinforced bifurcation, the design of intake and outlet based on bidirectional flow, the layout and excavation support design of large underground caverns under complex geological conditions, the hydraulic transient design of high head water conveyance and power generation system, the key technical parameter selection for 700m high head pumped storage units, the application of pumped storage variable speed unit technology, and the coordination of project layout and ecological environment, etc.

In addition, BJEC has prepared the sector technical standard “Code for Design of Pumped Storage Power Stations”, which provides a strong support for the construction of pumped storage power stations in China.
