Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy.

Incorporating energy storage as a virtual inertial course would require fundamental changes in grid operations and market design. Because grid rotational inertia is considered an inherent property of power generation, there is no market mechanism to include inertia generation as an ancillary service.
Energy storage technologies have emerged as a viable alternative to providing inertia through virtual inertia, i.e. inertia generated or simulated with power electronics and controls (Zhao and Ding, 2018, Zhang et al., 2019, Fang et al., 2017a).
Power system engineers typically describe the inertia of a generator in terms of stored rotational kinetic energy (EPRI 2019), so inertia has the same units of energy (power delivered over a period of time).
This makes inertia incredibly important to the stable operation of the electricity system. Many generators producing electricity for the grid have spinning parts – they rotate at the right frequency to help balance supply and demand and can spin faster or slower if needed. The kinetic energy ‘stored’ in these spinning parts is our system inertia.
Inertia from rotating electrical generators in fossil, nuclear, and hydroelectric power plants represents a source of stored energy that can be tapped for a few seconds to provide the grid time to respond to power plant or other system failures.
