China wind energy statistics

China is currently the second largest wind power producer, and at the end of 2009, wind power in China accounted for 25.1 GW of electricity generating capacity. If current trend continues China will in 2011 overtake US, and became the world's largest wind power producer.  China's installed wind farm capacity is expected to grow from present 25,800 MW to over 150,000 MW in 2020.

At the end of 2009 China had around 80 operational wind farms. In 2009 China built its first offshore wind farm, close to Shanghai Dongdaqiao, with a capacity of 102 MW. In fact, China plans to generate up to 30,000 megawatts of power from offshore wind farms by 2020.

In the last 5 years, China has each year more than doubled its wind power capacity, and the biggest growth occurred in 2009 when China added 13,800 MW of new wind power capacity.

China is also the world's largest wind turbine manufacturer. The latest numbers suggest that China manufactures 2 wind turbines per hour.

China still doesn't have enough transmission lines to support the growth of wind power industry, and according to recent data from the China Power Union, only 72% of China’s total wind power capacity was connected to the grid. This is the main reason why Chinese have embarked on a $60 billion effort to upgrade the country’s electricity transmission system over the next 10 years.

Wind power still accounts for only 1 percent of China's total electricity consumption despite the very strong growth in the last couple of years.

In 2000, China only had 350,000 kW of installed wind power capacity.

In 2009, around 50% of the large capacity windmills installed in China were manufactured in Denmark.
