China Longyuan Power Group completed its 150-megawatt Jiangsu Rudong pilot intertidal wind farm off China's east coast in November, becoming the country's largest offshore wind farm.

The project was approved by the National Development and Reform Commission as a national pilot program in December 2010. It can generate about 375 million kilowatt- hours of power every year, with more than 2,500 hours of wind power available annually.

Compared with conventional coal-fueled power plants, it can save the equivalent of about 110,000 metric tons of standard coal every year, while cutting carbon dioxide emissions.
