Jan. 29, 2008--American Superconductor Corporation (NASDAQ: AMSC), a leading energy technologies company, today announced that it has received more than $3 million in orders for its wind turbine core electrical components and systems from two AMSC Windtec customers: China's CSR Zhuzhou Electric Locomotive Research Institute ("CSR-ZELRI") and Canada's AAER, Inc. AMSC's electrical systems include the company's proprietary PowerModule(TM) power converter and enable reliable, high-performance wind turbine operation by controlling power flows, regulating voltage, monitoring system performance and controlling the pitch of wind turbine blades to maximize efficiency.
"These most recent orders demonstrate AMSC Windtec's unique ability to get new wind turbine manufacturers up and running quickly in a dynamic marketplace," said Greg Yurek, founder and chief executive officer of AMSC. "With ZELRI placing repeat orders for electrical systems and AAER making its first purchases, our customers are signaling the commencement of their production ramp ups to meet the growing demand for zero-emission wind turbines worldwide."
