The objective of this project is to demonstrate the viability of grid frequency regulation
using a high-energy Flywheel Energy Storage System (FESS), which is designed to respond to regulation signals.
It is expected that the FESS will facilitate faster response to regulation signals and will allow generators
to operate at higher output levels for optimum efficiency and lower emissions. Improvements in power quality
are also anticipated.
For this demonstration, Beacon Power was chosen to install a test system consisting of seven Beacon BHE6 flywheels modified with a larger motor. The flywheels can produce a total of 100kW for 15 minutes. Besides frequency regulation, the system can provide additional capabilities, including UPS (uninterruptible power supply) and VAR (volt-amperes reactive power) to help stabilize the local grid.
Partners in this demonstration include:
- Beacon Power (equpment manufacturer and prime contractor)
- NYISO

- Power & Composite Technologies
- NationalGrid (formerly Niagara Mohawk) (utility)
- EnerNex Corporation (data acquisition and monitoring)

The location chosen for installation of the flywheel energy storage system is an industrial site in Amsterdam,
NY. The system is housed in a modified steel shipping container mounted on concrete footings. Internet
connectivity is provided via a fiber optic connection provided by PCT. The system is connected to the
distribution grid of National Grid (formerly Niagara Mohawk).
Energy Storage System

The energy storage system used in this demonstration project is a scale-power Smart Energy Matrix
designed and manufactured by Beacon Power. The system consists of seven four-rotor flywheel units.
The system operates at 480 VAC and is capable of supplying up to 100 kW for fifteen minutes.
