A flywheel-storage power system uses a flywheel for grid energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. FESS is used for short-time storage and typically offered with a charging/discharging duration between 20 seconds and 20 minutes. When excess electricity is available, it is used to accelerate a flywheel to a very high speed. The energy is stored as kinetic energy and can be retrieved by slowing down the flywheel. . High-speed flywheels- made from composite materials like carbon fiber and fiberglas, typically operate at speeds between 20,000 and 60,000 revolutions per minute (RPM) and can store energy for a few seconds to a few minutes. Flywheels can store grid energy up to several tens of megawatts.

Energy storage is the capturing and holding of energy in reserve for later use. Energy storage solutions for electricity generation include pumped-hydro storage, batteries, flywheels, compressed-air energy storage, hydrogen storage and thermal energy storage components. . Energy can be stored in a variety of ways, including: Pumped hydroelectric. When water is released from the reservoir, it flows down through a turbine to generate electricity. By introducing flexibility into how. .
