China will strive to reduce renewable power idling to a minimum by 2020, the country's National Energy Administration (NEA) said on November 13.
Power from wind, solar and hydro plants is often wasted as power transmission system is inadequate and its generation volatility often make it conflict with coal-fired power, especially in north and northwestern regions, where both wind/solar and coal resources are rich.
The utilization rate of hydro plants in the southwestern provinces of Yunnan and Sichuan should reach around 90% by the end of this year, the NEA said in a statement as one of multi steps to realize the target.
By the year's end, meanwhile, wind power idling rate should drop to 30% or so in the northwestern provinces of Gansu and Xinjiang, and to 20% in Jilin, Heilongjiang and Inner Mongolia, the northeastern region of China.
Solar power waste in Gansu and Xinjiang provinces should be below around 20% and in Shaanxi and Qinghai to below 10% this year, it added.
Wind and solar power plants in other regions across the country will have to meet the 2017 targets set by the NEA last year, it said in the statement, but not mentioned the details of the target.
China has vowed to raise the portion of its renewable and non-fossil fuel power consumption to 15% of total energy mix by 2020 and 20% by 2030.
It also said that China will promote market-oriented power trades, improve its trans-regional power transmission capacity and get rid of its coal dependence.
Coal-fired power capacity will be capped at 1.1 TWh across the country by 2020, the NEA said.
