DEVENS, MA - November 18, 2009 - American Superconductor Corporation (NASDAQ: AMSC), a global power technologies company, today announced that it has received a follow-on order for 30 sets of electrical control systems from Hyundai Heavy Industries Co., Ltd. (Korean Stock Exchange: HHI) for its 1.65 megawatt (MW) wind turbines now in production in South Korea. AMSC also has received an electrical control systems order for HHI's 2 MW wind turbine prototypes. All of the systems will be shipped to HHI by the end of May 2010.

AMSC's wind turbine electrical control systems and core electrical components include the company's proprietary PowerModule power converters, pitch and yaw converters, SCADA systems and other power electronics. They enable reliable, high-performance wind turbine operation by controlling power flows, regulating voltage, monitoring system performance, controlling the pitch of wind turbine blades and the yaw of the turbines to maximize efficiency.

Based in Ulsan, South Korea, HHI is the world's largest shipbuilder, a global leader in turnkey power plants and offshore projects, and a major global supplier of high voltage electrical equipment. HHI licensed 1.65 and 2 MW wind turbine designs from AMSC's wholly owned AMSC Windtec subsidiary in 2008. The company entered volume production of 1.65 MW wind turbines in October 2009 and plans to commence production of 2 MW wind turbines in 2010.

"HHI's investment in the wind power industry has created a new growth engine for our company," said Young N. Kim, Senior Executive Vice President and COO, HHI Electro Electric Systems. "Over the course of the past year, we have licensed high-quality wind turbine designs from AMSC Windtec, commissioned our first prototype systems and secured our initial wind turbine orders in Korea and the United States. We see tremendous growth opportunities in front of us and are expanding our wind turbine capacity to support our growth plans."

HHI installed and commissioned its first reference 1.65 MW wind turbine near its manufacturing facility in Ulsan, South Korea in June 2009, less than one year after licensing the design from AMSC Windtec. In September 2009, HHI announced Wave Wind, LLC as its first wind turbine customer in the United States. HHI has invested 105.7 billion won (nearly US$90 million) to build a wind turbine manufacturing plant in Gunsan with an annual capacity of 600 MW. The company plans to expand the capacity of the facility to 800 MW by 2013.

"HHI continues to scale its manufacturing operation and execute its aggressive growth strategy in the renewable energies market," said Timothy Poor, AMSC's Senior Vice President of Global Sales and Business Development. "This follow-on order follows close on the heels of the first electrical control system order HHI placed with us in August 2009, demonstrating that its 1.65 MW wind turbines are quickly gaining traction in the marketplace."
