Benefits from Flywheel Energy Storage for Area Regulation in California— Demonstration Results

Posted: October 1, 2009 - 19:00 / CAISO / Reports

This report documents results from a demonstration of flywheel electric energy storage (flywheels) for area regulation, an ancillary service required for electric grid operation. The work was sponsored by the California Energy Commission’s (CEC’s) Public Interest EnergyResearch (PIER) program and the U.S. Department of Energy’s Energy Storage Systems Program. The flywheel is made by Beacon Power Corporation (Beacon Power). 

In addition to demonstrating flywheels’ overall performance as a regulation resource, one key objective of the project was to demonstrate the presumed advantage that flywheels have over generation for regulation – the ability to vary power output rapidly and reliably.
