In , operates in a flywheel storage power plant with 200 flywheels of 25 kWh capacity and 100 kW of power. Ganged together this gives 5 MWh capacity and 20 MW of power. The units operate at a peak speed at 15,000 rpm. The rotor flywheel consists of wound fibers which are filled with resin. The installation is intended primarily for frequency c. Energy is stored in the Flywheel Energy Storage Systems by accelerating a rotor or flywheel to a very high speed and maintaining that energy as rotational energy. When electricity is needed, the flywheel decelerates and the stored kinetic energy is converted back into electrical energy. [pdf]

Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 to 13. With an array comprising 10 flywheel energy storage, this large-scale energy storage system is the world's largest setup. A leading example in renewable energy transition, China connects Dinglun Flywheel Energy Storage Power Station to grid. [pdf]
