Beacon Installs Flywheels for Pennsylvania Energy-Storage Plant

June 21, 2013

Beacon Power LLC, the maker of power-storage systems that was bought by Rockland Capital last year, began construction of a 20-megawatt flywheel system in Pennsylvania.

The project in Hazle Township will have 200 flywheels, Tyngsboro, Massachusetts-based Beacon said today in a statement. The first 4 megawatts of capacity will go into operation in September and the entire plant is expected to be running in the second quarter of 2014.

Beacon’s systems store power using 2,500-pound (1,134-kilogram) carbon-fiber cylinders rotating as fast as 16,000 times a minute. The kinetic energy can be quickly converted into electricity and transferred to the grid to meet sudden surges in demand.

The project will be the first flywheel storage system in use in PJM Interconnection LLC’s 13-state power market that stretches from Illinois to Delaware, according to the statement.

Beacon received a $43 million U.S. Energy Department loan guarantee to develop the technology and filed for bankruptcy in 2011. Rockland purchased Beacon’s assets in March 2012.
