Monrovia Electric Flywheel Energy Storage
Flywheel energy storage systems have numerous applications, including grid stabilization, backup power, and uninterruptible power supply (UPS) systems. Flywheels are also suitable for use in
They can be installed at the transmission or distribution levels or even in remote connected or isolated grids. The modular and distributed architecture of Beacon flywheel energy storage systems allows flexibility in power capacity as well as siting. A single flywheel module easily connects to others, allowing for incremental storage expansion.
In Ontario, Canada, Temporal Power Ltd. has operated a flywheel storage power plant since 2014. It consists of 10 flywheels made of steel. Each flywheel weighs four tons and is 2.5 meters high. The maximum rotational speed is 11,500 rpm. The maximum power is 2 MW. The system is used for frequency regulation.
Beacon Power operates three flywheel energy storage plants that provide frequency regulation service in three different US markets. There are more than 400 flywheels in commercial operation today helping grid operators in NYISO, PJM and ISO-NE safely and efficiently balance power grid supply and demand to ensure reliability.
Flywheel systems are kinetic energy storage devices that react instantly when needed. By accelerating a cylindrical rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy, flywheel energy storage systems can moderate fluctuations in grid demand.
