Beacon Power Corp. (Tyngsboro, Mass.), a company that designs and develops advanced products and services to support more stable, reliable and efficient electricity grid operation, announced that the U.S. Department of Energy (DOE) has completed its formal environmental review of Beacon's proposed 20-MW frequency regulation plant in Stephentown, N.Y., and issued a Finding of No Significant Impact (FONSI). In its determination, the DOE said that the plant "will not have a significant effect on the human environment."
This completes the environmental analysis of the project site that began in July 2008, when the Stephentown Planning Board approved the environmental aspects of the project, by issuing its own Negative Clearance and Determination of Non-Significance for the project.
Beacon's proposed 20-MW plant would provide frequency regulation
services by absorbing energy when it is abundant, storing it in a
flywheel energy storage system, and injecting it back as necessary to
help the grid maintain electricity frequency within a desired range (60
cycles/second being the target). Flywheels have been identified as a good candidate for composites application. Beacon's plant will not directly
produce greenhouse gas emissions or other air pollutants, nor will it
directly consume fuel, as do conventional fossil fuel-powered
generators that provide regulation today.
"This finding by DOE as to the minimal environmental impacts of our proposed 20-megawatt frequency regulation plant is a major step forward," said Bill Capp, Beacon president and CEO. "As the first loan guarantee finalist to complete the NEPA assessment through the Loan Guarantee Program Office, we look forward to DOE's completion of the remainder of the loan process in the near future."
