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.

For swap stations, stored swap packs can buffer peak demand. Storage buffers are used to reduce peak demand at DC fast charge stations, as these can use upwards of 150 kW. . This paper comprehensively reviews electric vehicle (EV) battery swapping stations (BSS), an emerging technology that enables EV drivers to exchange their depleted batteries with fully charged ones at designated stations. Battery storage is the fastest responding dispatchable. .
