BEIJING, April 28 -- China has seen a steady rise in its wind power capacity, with 4.7 gigawatts of on-grid capacity added in the first quarter of the year, the National Energy Administration announced on Tuesday.

China's total on-grid wind power capacity reached 101 gigawatts by the end of March, surpassing the 100-gigawatts target by 2015 set by the government, according to the administration.

During the January-March period, China's wind farms produced 45.6 billion kilowatt hours of electric power, up 18.6 percent year on year, the data showed.

China has been working to increase its share of non-fossil fuels in the power mix, including hydropower, wind power, solar power and nuclear power.

The State Council released an action plan on energy development for 2014-2020 last November, promising more efficient, self-sufficient, green and innovative energy production and consumption.
