On September 16, the 220kV transmission project of the National Demonstration Project of Dalian VRFB energy storage power peak shaving station was officially launched. The project started construction in November 2016 and is scheduled to be completed and put into operation in December 2020.
Located in Xigang District, Dalian, the project is the first large-scale chemical energy storage national demonstration project approved by the National Energy Administration, and the only chemical energy storage peak shifting power station in China. The construction scale reaches 200 MW/800 MWh, with a total construction area of 36,519 square meters and a total investment of 3.8 billion yuan. It adopts the VRFB energy storage technology, which is independently researched and developed in China and has independent intellectual property rights. It is suitable for high-power and large-capacity energy storage with good safety, long cycle life, fast response speed, high energy conversion efficiency, green environmental protection and other advantages.
After the completion of the project, it can play a dual role of peak shaving and valley filling, which is of great significance in improving the peak regulation capacity of Dalian Power Grid and the power supply reliability in southern Dalian, ensuring the safe and economic operation of the power grid, improving the power structure of Liaoning power grid, providing favorable conditions for the development of wind power, and promoting the application and development of energy storage technology.
