“Restrictions on power caused by waste wind have already become a major problem impacting the healthy development of the wind power sector,” the National Energy Administration said on its website. Energy from wind can be stored in batteries or by raising the elevation of water that is then run downhill when water is needed, but the related infrastructure is needed to do so.
China’s total wind power capacity reached 133.3 gigawatts by the end of February, making up 9 percent of its total, but generation levels, at 168 billion kWh, accounted for just 3 percent of the national total in 2015. Critics have accused local governments of focusing on capacity rather than efficiency and utilization, hitting renewable energy targets by building windfarms in regions plagued by low wind speeds and insufficient grid capacity.
The regulator said it would create a power trading mechanism to transmit wind power across provincial and regional boundaries, besides taking action to make sure increases in generation and transmission capacity go hand-in-hand.
China aims to raise the share of non-fossil fuels in its primary energy mix to 15 percent by the end of 2020, up from 12 percent in 2015.
