Flywheel energy storage (FES) works by spinning a rotor (flywheel) 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 in an increase in the speed of the flywheel. W. Main componentsA typical system consists of a flywheel supported by connected to a . The flywheel and sometimes motor–generator may be enclosed in a to reduce fricti. .
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. .
In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have.

How TEC is powering Tuvalu with renewable resources?
TEC has set a vision of “Powering Tuvalu with Renewable Resources” and this align well with the Tuvalu Government set target of 100% renewable energy by 2025. All the islands of Tuvalu are on 24/7 power supply and the access rate is 100%. The outer islands are powered by hybrid solar PV system with diesel generator on standby.
Does Tuvalu have solar power?
All the islands of Tuvalu are on 24/7 power supply and the access rate is 100%. The outer islands are powered by hybrid solar PV system with diesel generator on standby. For the main island of Funafuti there are some solar PV systems tied to the grid with diesel base load generators.
Why is there a temporary power shedding in Tuvalu?
The Tuvalu Electricity Corporation (TEC) wishes to inform all residents that temporary power shedding will be implemented across affected areas due to a shortfall in available generation capacity. Recent technical challenges and scheduled maintenance have reduced the output of our power generation capacity.

Since they do not have any mechanical parts, battery storage power plants offer extremely short control times and start times, as little as 10 ms. They can therefore help dampen the fast oscillations that occur when electrical power networks are operated close to their maximum capacity or when grids suffer anomalies. These instabilities – fluctuations with periods of as much as 30 sec.
