First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass.OverviewFlywheel 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. .
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 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.

Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in , and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. The first pumped hydroelectricity was constructed at the end of the 19th century around in Italy, Austria, and Switzerland. The technique rapidly expanded during the 196.

Ravenswood was originally built and owned by of New York Inc. (Con Edison) in 1963. The first two units constructed in 1963 were Ravenswood 10 and 20, each having a generating capacity of approximately 385 . Then, in 1965, Ravenswood 30 (commonly called "") was commissioned with a generating capacity of nearly 981 megawatts. A new 1,000 MW unit was originally planned to be located on the north side of the

Citywide compressed air energy systems for delivering mechanical power directly via compressed air have been built since 1870. Cities such as , France; , England; , , and , Germany; and , Argentina, installed such systems. Victor Popp constructed the first systems to power clocks by sending a pulse of air every minute to change their pointer arms. They quickly evolved to deliver power to homes and industries. As o.
