Abstract: The design task of pumped storage project is heavy, the time is limited, and there are many disciplines involved. Therefore, traditional design methods are unable to satisfy the current situation and requirements. Using BIM technology, through meticulous application planning, the collaborative design is carried out, covering surveying, civil engineering, mechanical and electrical engineering, and other re - lated disciplines. It can significantly improve the rationality of design schemes, enhance the accuracy and quality of design results, increase the diversity of results, liberate the productivity of designers, and provide a solid foundation for the application of digital twin pumped storage power stations. This study briefly describes the way to choose a suitable 3D digital collaborative design solution for pumped storage power stations and carry out 3D digital design, as well as the value and advantages of 3D digital technol- ogy in the design stage of pumped storage power stations.

Key words: pumped storage power station, 3D, digitization, collaborative design, BIM
