en.Wedoany.com Reported - The upper reservoir dam of the Zhejiang Jiangshan Pumped Storage Power Station project has completed the 20th layer of filling, marking the entry of the main dam filling construction into a large-scale and standardized phase.
This project is a key initiative in the national medium- and long-term development plan for pumped storage, with a total installed capacity of 1,200 megawatts, planned to install four reversible pump-turbine generator units, each with a capacity of 300 megawatts. Once completed, the power station will undertake functions such as peak shaving, valley filling, energy storage, and frequency regulation for the power grid, serving as the core energy storage support for the construction of a new-type power system in western Zhejiang.
The upper reservoir dam is the core controlling project, with high construction standards and significant technical challenges. Since the start of filling construction, the project team has focused on the three main lines of safety, quality, and progress, optimizing construction plans and refining processes such as layered filling, compaction testing, and settlement observation. Construction personnel have implemented round-the-clock shift operations, precisely controlling key parameters such as stone material spreading, compaction degree, and moisture content to address difficulties like complex terrain and tight schedules, ultimately achieving the milestone of completing the 20th layer of filling.
The completion of this milestone has verified the feasibility of the construction techniques and management system. Currently, the overall project construction is progressing steadily, with multiple sub-projects being completed on schedule. In the next phase, the project team will continue to advance the subsequent dam filling and supporting works, striving for the early commissioning of the project.
