en.Wedoany.com Reported - On May 12, the groundbreaking ceremony for the 400MW/1.2GWh new-type independent energy storage project was held in Weiyang District, Xi'an, Shaanxi Province, China. With a total investment of over 2.2 billion yuan and covering an area of approximately 88 mu, this new-type energy storage project has a maximum single charge/discharge capacity of 1.2 million kWh, enough to meet the daily electricity needs of 60,000 households.
The project utilizes a hybrid energy storage technology combining lithium iron phosphate and all-vanadium redox flow batteries, offering the dual advantages of rapid response and long-duration energy storage. This hybrid technology will enable the project, once completed and connected to the northern Xi'an power grid, to achieve millisecond-level response times and an annual discharge capacity of up to 610 million kWh. It can charge and store energy during off-peak hours and discharge to supplement supply during peak hours, thereby alleviating peak-shaving pressure on the regional power grid.
The project's construction adheres to an eco-friendly philosophy, employing mature energy storage technology and a comprehensive supporting system for safety monitoring and environmental protection. It features a short construction period with minimal construction impact, and once operational, it will produce no exhaust gas, noise, or solid waste emissions. The project will be developed into a regional demonstration site for new energy science popularization and green ecology. The SCEGC No.7 Construction Engineering Group is responsible for advancing the project. The group has already obtained an electricity sales qualification, with its business covering areas such as waste-to-energy incineration for power generation, clean heating, energy storage power stations, and photovoltaic power generation, thereby establishing a closed-loop green energy ecosystem.
The commencement of this project represents a concrete action by Weiyang District to implement the national dual carbon goals and develop new quality productive forces. Once completed, this new-type energy storage project will enhance the power supply security capability of northern Xi'an, drive the upstream and downstream aggregation of the energy storage industry chain, and inject momentum into the green transformation of the regional energy structure.
