BEIJING - Vestas, the world's largest wind turbine manufacturer, has recently won a large contract from China Datang Corporation Renewable Power, said Vestas China Tuesday in Beijing.

The contract includes an order for 25 two-megawatt wind turbines, which will be installed near the city of Hulunbuir in North China's Inner Mongolia autonomous region. The turbines are scheduled to be delivered in the second quarter of 2011.

The climate in Hulunbuir is extremely harsh during most of the year. High winds and low temperatures mean that the window of time safe to install the turbines is around five months, starting from early May.

"Completing a 50-megawatt project in a window of five months is not easy, but we definitely believe we have the right people for this task," said Jens Tommerup, president of Vestas China.

Vestas installed China's first wind turbines in Shandong in 1986. Vestas turbines provided nearly 3,000 megawatts of clean energy in thirteen of China's provincial regions as of December 2010. This makes Vestas one of the biggest suppliers of wind power in China.

Vestas has worked with Datang on many projects since 2005, with a total of 800 megawatts of power capacity installed to date.
