In 2009, Beacon Power got its big break, receiving a $43MM Department of Energy grant to build the 20-megawatt flywheel plant in Stephentown, NY a small town with a population of just 2,903. In total, the flywheel storage plant would cost $69MM, so the $43MM DoE grant paid for the majority of the project''s costs.

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