Beacon Power to begin construction of flywheel facility

The 20-MW flywheel frequency regulation plant in Stephentown, N.Y., will store energy from renewable sources.

Beacon Power Corp. (Tyngsboro, Mass., USA), a company that designs and develops advanced products and services to support more stable, reliable and efficient electricity grid operation, announced on Nov. 10 that it will begin construction of the nation’s first full-scale 20-MW flywheel frequency regulation plant during the week of Nov. 23, at its site in Stephentown, N.Y. Composites-intensive flywheel systems are designed to store energy from renewable sources, like wind and solar.

All state and local construction-related permits and approvals for the plant have now been received. Beacon will start initial site work while continuing to progress toward closing a $43-million loan with the Federal Finance Bank, with the support of the U.S. Department of Energy and a loan guarantee commitment that Beacon received earlier this year. The loan is intended to support construction of the plant.

“We’re extremely pleased to be breaking ground on our first 20-MW flywheel plant this month,” said Bill Capp, Beacon president and CEO. “Thanks to the support of a number of agencies, organizations and individuals, including the Federal Energy Regulatory Commission, Department of Energy, New York ISO, the New York State Energy Research and Development Authority and the Public Service Commission, as well as local officials in Stephentown, we can now move forward with construction.”
