Growth in the on-grid wind power capacity was up 87% annually over the last six years. Grid linked capacity will rise to 100 gigawatts by 2015 and 200 gigawatts by 2020.

　　China, the world largest emitter of greenhouse gases plans to have at least 15% of its energy mix come from non-fossil fuels by 2020. Wind farms are the second-biggest contributor to renewable-energy capacity in the nation after hydropower dams.

　　Regional concentrations of wind resources and a lack of links between local electricity networks and the national grid prevent the efficient use of wind power.

　　Mr Shu Yinbiao a deputy general manager at State Grid said China needs to accelerate the construction of trans- regional grids to meet its energy-development targets.
