Frequency Regulation
Benefit of Flywheel Based Frequency Regulation
Frees up generator capacity
Fast response may reduce quantity of
necessary frequency regulation
Gives ISO another option
Benefit for deployment of wind power
Environmental
No direct fossil fuel consumption
Zero plant emissions
Increases the Reliability and Stability of the Grid
Business Strategy
Flywheel Based Frequency Regulation
Beacon’s Market Strategy
Sell frequency regulation service instead of product
Provide services via deregulated open-bid markets
Qualify with scale-power demonstration testing
Commercialize with 25 kWh Gen 4 flywheel
1st service revenues in 2007 (1 MW)
10 to 20 MW of service revenues in 2008
Beacon Power’s
Gen4 Flywheel
