A flywheel-storage power system uses a for , (see ) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage. Unlike common storage power plants, such as the

There are currently two main types of power plants operating in : (1) and (2) or power plants. With a total installed capacity of (81 percent of the total) in early 2014, thermal power plants (gas-fired plants) dominate the Nigerian power supply mix. Electricity production from hydroelectric sources (% of total) in Nigeria was reported at 17.59% in 2014, according to the World Bank collection of development indicators, compiled from officially recog.

Flywheel energy storage (FES) works by spinning a rotor () and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of ; adding energy to the system correspondingly results in an increase in the speed of the flywheel.

Flywheel energy storage (FES) works by spinning a rotor () and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced a. .
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.
