With 200 flywheels spinning, Beacon Power's flywheel energy storage plant in Stephentown, New York has reached full capacity! Storing and returning a total of 20MW to the grid, the plant is the largest of its kind in North America and provides New York with 10% of its overall frequency regulation needs. The plant is a positive step towards meeting NYSERDA's ambitious goal of meeting 45% of the states electricity needs through energy efficiency and renewable energy.
Flywheel energy storage works by converting power from the grid to rotational energy by spinning carbon fiber flywheels at Mach 2 speeds, the energy is then transmitted back to the grid to buffer disturbances without burning fossil fuels.
