China’s Wind Power Industry Aims To Keep Wind And Solar Curtailment Rate Under 9 Percent

According to data released by the National Energy Administration of China, the country added wind power grid-connected capacity of 3.94 GW during the first quarter of this year, a year-over-year increase of 12 percent. The country’s average wind curtailment rate had decreased to 8.5 percent as of the end of the quarter, down 8 percentage points from a year earlier.

In regions where the State Grid Corporation of China has a presence, wind curtailment decreased 53 percent or 11.2 percentage points while that of solar dropped 32 percent or 6.1 percentage points year on year, laying a good foundation for the country’s goal of maintaining an average curtailment rate for wind and solar combined under 9 percent for the whole year 2018. 

The National Energy Administration released the unofficial draft of the clean energy absorption plan this April, stipulating a target solar curtailment rate of under 5 percent and that of wind under 12 percent for 2018, under 5 percent and 8 percent for 2019, respectively, and both to drop under 5 percent for 2020.

The State Grid Corporation of China traded 18.9 billion kilowatt-hours of renewable and alternative energy, referred to in China as “new energy,” between provinces and regions for the first quarter of this year, an increase of 65.2 percent compared to the same period of last year. 

Transactions for electricity between regions amounted to 2.87 billion kilowatt-hours for the same period, up 113 percent year on year. Direct trading between large users in provinces participating in the new energy scheme reached 2.82 billion kilowatt-hours of electricity, up 89.6 percent compared to a year earlier. 

To keep the wind curtailment rate under 9 percent in 2018, China has continued the sustainable and friendly clean energy absorption policy. The country kicked off new energy market-oriented trading mainly in two forms: the nearest absorption of distributed energies, which participate in regional electricity market trading, and the interprovincial and interregional transactions, which aim to rebalance the availability of energy when an imbalance between regions occur, as well as to spread the ability to rebalance over a larger geographical area.

The National Energy Administration issued the notice on lightening the burden on firms in the renewable energy sector in April, introducing several measures to help firms in the sector dispose of non-technological costs in clean energy industries, including wind and solar. Non-technological costs include wind power resource costs illegally collected by regional governments, other investments connected with wind and solar resources and access costs illegally collected by power grid companies. 

Data revealed that China witnessed 5.34 GW of wind power installations for the first four months of this year, increasing 931 MW compared to the same period of last year. The country recorded wind curtailment of 9.1 billion-kilowatt hours and a wind curtailment rate of 8.5 percent for the same period, with the latter number down 7.9 percentage points from a year earlier.
