American Superconductor Corp. (AMSC), a supplier of wind-turbine components, rose the most in more than a month after winning a contract to supply 100 megawatts of electrical systems to India’s Inox Wind Ltd.
American Superconductor rose 13 percent to $3.99 a share at the close in New York, the most since April 11.
Inox designed a two-megawatt wind turbine using American Superconductor technology in 2009 and today ordered 50 of its electrical control systems to use in turbines this year, the Devens, Massachusetts-based company said today in a statement.
