Energy Services and EVs
Beacon Power Corp. has delivered and put in place the initial flywheel power electronics and associated support equipment as part of the construction of what the company calls the world’s first grid-scale flywheel energy storage plant in Stephentown, N.Y. The systems, consisting of power electronics, cooling and other support equipment housed in specially equipped containers, were lowered onto permanent foundations. After the containerized systems are wired in place, they will be interconnected with Beacon flywheels. Support equipment for a total of 4 MW of energy storage capacity was delivered to the site. Eighty flywheel foundations already have been installed, and the company is delivering and installing 40 flywheels (4 MW) during the third quarter of this year. The 4 MW of storage capacity is expected to be connected and earning revenue from frequency regulation services by the end of the fourth quarter. The balance of the 20-MW plant is expected to be completed and operational by the end of the first quarter 2011.
The University of Michigan solar car crossed the finish line first at the American Solar Challenge Race in Naperville, Ill. The race started in Broken Arrow, Okla., and over the course of six days, the car called Infinium traveled 1,100 miles averaging 40 mph. Seventeen teams from the United States, Canada, Germany and Taiwan competed. In order to keep the car weight down, a primary light-weight component of the car included car battery enclosures designed by StahlinWorldwide. The fiberglass composite material met both weight and rigidity requirements for the vehicle, and the company says the material translates well into uses for renewable power storage.
Cape Light Compact , an inter-municipal utility serving 21 communities near Cape Cod, Mass., reports that participants in a year-long conservation pilot program reduced daily energy use by 9.3 percent or 2.9 kWh/day.
