Beacon's flywheel energy storage system (FESS) was located at Pacific Gas and Electric’s San Ramon research center. It employed seven 6-kilowatt-hour flywheels, each the size of a small refrigerator, ganged together to form a system that could absorb or discharge 100 kilowatts of power for 15 minutes.
