New York to Have First Flywheel-Based Energy Storage System

Beacon Power Corporation recently start construction of the world’s first 20MW flywheel energy storage plant in Stephentown, New York after it received a $43 million loan guarantee from U.S. Department of Energy. According to the company, their flywheel electricity storage systems will provide efficient, frequency regulation services to help maintain and improve stability of the New York mains power grid and also allow greater use of solar and wind energy.
The working principle of this system is not so complicated. It works by accelerating a flywheel ( the rotor) to very high speeds and keeping the energy in the system as rotational energy, which is converted back to electricity by slowing down the flywheel.
When is too much electricity on the grid, the flywheel batteries will absorb it and when there’s not enough will use it by injecting the energy back into the mains grid. Beacon Power Corporation states that 30 to 50MW of fast-response electricity storage can be expected to generate the same regulation effect as a combustion turbine of 100MW.
The company also said that by the end of this year, 4MW storage flywheel batteries at the plant is expected to be online and the rest of 16MW to be available by the first quarter of 2011.
