Under the terms of the alliance, the 5 MW wind turbine design will be jointly developed by HHI and AMSC’s wholly-owned AMSC Windtec subsidiary. Once HHI begins volume production of the wind turbines, which the companies expect to commence by the end of 2011, HHI will purchase power electronic components for the 5 MW wind turbines from AMSC.

In October 2008, AMSC Windtec licensed 1.65 and 2 MW doubly-fed induction wind turbine designs to HHI. HHI has now begun volume production of the 1.65 MW wind turbines.

“With sales of our 1.65 MW wind turbines increasing according to plan and production of our 2 MW wind turbine set to begin, we are ready to add another advanced system to our renewable energy portfolio,” said Keh-Sik Min, Chairman and Chief Executive Officer of HHI. “While we expect our 1.65 and 2 MW wind turbines to be our onshore ‘workhorses,’ the global offshore wind market holds tremendous growth potential for HHI. We are pleased to expand our strategic alliance with AMSC and broaden our portfolio with an advanced 5 MW platform for this emerging opportunity.”

Under the terms of the new development contract, HHI will have the ability to market, manufacture and sell 5 MW wind turbines globally.

“Our strategic alliance with HHI continues to grow along with the strong expansion of their global wind power business,” said AMSC founder and Chief Executive Officer Greg Yurek. “Within a two-year period, HHI has formed a new wind energy division and will have brought two high-performance, megawatt-scale wind turbines to market – a feat few have accomplished in the industry. HHI now aims to establish a leadership position in the offshore wind turbine market.”
