ALBANY, N.Y. - A plan to build an
array of 200 flywheel batteries to store spare power
from New York's electrical grid and transmit it
back when needed has been approved by state regulators.
The state Public Service Commission
authorized Stephentown Regulation Services LLC to
construct and operate the seven-acre facility in
Stephentown, near the Massachusetts line. The flywheel
batteries will weigh a ton, levitate in a sealed
chamber and spin up to 16,000 times per minute.
The U.S. Department of Energy has granted the company
a $43 million conditional loan guarantee to build
the 20-megawatt plant. The PSC says Thursday the
company will still have to obtain necessary federal,
state, and local permits and approvals. Stephentown
Regulation is a subsidiary of Tyngsborough, Mass.-based
Beacon Power Corp.
