China's electrical grids will connect 90 million kilowatts of wind power capacity in 2015, said China's largest power grid company on Friday.

The figure will rise to 150 million kilowatts in 2020, said the State Grid Corporation of China (SGCC) in a white paper on wind power development.

The market for wind power consumption is found primarily in northern China, eastern China and central China, while wind power farm projects are largely located in northern China, northeastern China and northwestern China, making it necessary to boost grid infrastructure construction, according to the white paper.

The SGCC vowed in the white paper to increase wind power transmission grids in the next five years.

China's wind power installation has doubled every year for the past five years. It totaled approximately 40 million kilowatts in 2010, ranking first in the world.

Currently, China's installed wind power capacity connected to national grids is above 30 million kilowatts, according to the white paper.
