A leading example in renewable energy transition, China connects Dinglun Flywheel Energy Storage Power Station to grid.
China has successfully connected its 1st large-scale standalone flywheel energy storage project to the grid. The project is located in the city of Changzhi in Shanxi Province. The power output of the facility is 30 MW and it is equipped with 120 high-speed magnetic levitation flywheel units. A single energy storage and frequency regulation unit is made from 10 flywheels. Then, 12 such units form an array which is connected to the power grid at a voltage of 110 kV.
The project is pioneering the use of a semi-buried underground well system. It is designed to provide a safe environment for waterproofing, cooling, operation, and maintenance of the flywheel unit.
The construction of the Dinglun Flywheel Energy Storage Power Station began in July 2023. Technology is provided by BC New Energy and construction was led by China Energy Construction, Shanxi Power Engineering Institute and Shanxi Electric Power Construction Company. Shenzhen Energy Group was the main investor.

About Flywheel Technology
Flywheel energy storage technology is a mechanical energy storage form. It works by accelerating the rotor (flywheel) at a very high speed. This maintains the energy as kinetic energy in the system. This technology has high power and energy density, rapid response and is highly efficient in comparison to pumped hydro or compressed air.
