First 20 MW Plant - Construction
The world's first grid-scale, flywheel-based energy storage plant is being built in Stephentown, New York. When completed, the 20 MW plant will operate continuously, storing and returning energy to the grid to provide approximately 10% of New York's overall frequency regulation needs. More information on the frequency regulation service and how Beacon Power flywheels provide it can be found here.
August 2010 - Construction activity in Stephentown continues to proceed smoothly with significant portions of the plant's infrastructure and electronics now in place. The project remains on schedule for commissioning 4 MW of flywheel regulation capacity in Q4 2010.
