Image: Shenzen Energy Group. A project in China, claimed as the largest flywheel energy storage system in the world, has been connected to the grid. The first flywheel unit of the Dinglun Flywheel Energy Storage Power Station in Changzhi City, Shanxi Province, was connected by project owner Shenzen Energy Group recently.
This flywheel storage system, developed by Shenzhen Energy Group with technology from BC New Energy, consists of 120 high-speed magnetic levitation flywheel units. These units are designed to store energy in the form of kinetic energy by spinning flywheels at high speeds.
Since flywheels are featured by the smooth transition between energy import and export according to the amount of demanded energy, they are deemed as a vital element in energy-generating systems . Currently, FESSs offer rapid energy support in vast project scales, where economic feasibility is the dominant factor for their installation.
The Dinglun Flywheel Energy Storage Power Station, the World’s Largest Flywheel Energy Storage Project, represents a significant step forward in sustainable energy. Its role in grid frequency regulation and support for renewable energy will help stabilize power systems as China continues to increase its reliance on wind and solar energy.
Our standardized photovoltaic power generation and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
