Washington, DC, U.S.A. --- (METERING.COM) --- August 10, 2010 - The U.S. Department of Energy has funded two projects to develop energy storage options aimed at improving the stability and reliability of New York’s power grid.

Last week a $17.1 million loan guarantee was awarded to AES Energy Storage, LLC to support the construction of a 20 MW energy storage system using advanced lithium-ion batteries.  The project, located in Johnson City, NY, will include advanced lithium-ion battery cells from A123System, Inc., with the contained battery and related electrical systems assembled, tested and validated in an A123 manufacturing facility in Hopkinton, MA.  

Yesterday a $43 million loan guarantee was finalized for Beacon Power Corporation’s 20 MW innovative flywheel energy storage plant in Stephentown, NY. Beacon’s Gen 4 flywheel system is specifically designed to perform frequency regulation on utility grids by absorbing and discharging energy to balance power generation and consumption on the electric grid, and the technology operates by using flywheels to quickly store and release from the grid in order to follow rapid changes in grid demand.

These technologies should reduce carbon emissions by 70 to 80 percent compared with to a coal, gas or pumped hydro plant.

“This project demonstrates our ongoing commitment to helping bring clean technologies to market,” said Secretary Chu, commenting on the Beacon project. “We will continue to support the development and deployment of innovative energy systems like this energy storage project that support our goal of expanding renewable energy generation and reducing greenhouse gas emissions.”
