September 17, 2003 by Jeff Shepard

American Superconductor Corp. (AMSC, Westborough, MA) announced that AMSC's Dynamic Volt-Ampere-Reactive (D-VAR®) transmission grid reliability system will be used by wind farm developer Mendota Hills LLC. The system will provide reactive power support and regulate voltage at a wind farm located approximately 100 miles west of Chicago.

The D-VAR system will enable the wind farm to meet the standards required for interconnection to Commonwealth Edison's electrical power grid in Illinois. The D-VAR system solution will be located at the wind farm site in Lee County, IL. It includes a four MegaVAR (MVAR) D-VAR system and two capacitor banks controlled by the D-VAR system. The wind farm's turbines are expected to generate about 50MW of electric power, enough to supply more than 12,500 homes.
