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. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results i. A typical system consists of a flywheel supported by connected to a. The flywheel and sometimes motor–generator may be enclosed in a to reduce friction an.

A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
Battery storage is one of several technology options that can enhance power system flexibility and enable high levels of renewable energy integration.
The state of charge influences a battery's ability to provide energy or ancillary services to the grid at any given time. Round-trip eficiency, measured as a percentage, is a ratio of the energy charged to the battery to the energy discharged from the battery.
For example, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity will have a storage duration of four hours. Cycle life/lifetime is the amount of time or cycles a battery storage system can provide regular charging and discharging before failure or significant degradation.
Battery Energy Storage Systems (BESS) can be utilized to provide three types of reserves: spinning, non-spinning, and supplemental reserves. Spinning reserves refer to the reserve power that is already online and synchronized with the grid. It is the first line of defense during a grid disturbance and can be dispatched almost instantaneously.
Most of the BESS systems are composed of securely sealed, which are electronically monitored and replaced once their performance falls below a given threshold. Batteries suffer from cycle ageing, or deterioration caused by charge–discharge cycles. This deterioration is generally higher at and higher. This aging causes a loss of performance (capacity or voltage decrease), overheating, and may eventually lead to critical failure (electrolyte leaks, fire, explo.
