BEIJING, March 30 (Xinhua) — China’s wind and solar power generation capacity continued to grow in 2016, but the proportion of waste from these clean energy electricity increased significantly, an industry report said Thursday.
The “China Energy Development Report 2016” released by the State Grid Planning and Design Institute, a think tank under China Energy Engineering Group, pointed out that the phenomenon of power abandonment is increasing, affecting the sustainable development of China’s new energy.
In recent years, China has been encouraging the development of clean energy to reduce its heavy reliance on coal, which accounts for about 72 percent of its energy consumption structure.
However, the rush to build wind farms in resource-rich northern regions led to a serious overdevelopment problem: power generation soon exceeded local demand, and there was insufficient transmission to move the electricity elsewhere, or it was not economically feasible to do so.
The amount of abandoned wind power was nearly 50 billion kWh, accounting for 17% of the total wind power generation, an increase of 2 percentage points over the previous year; about 20% of solar power generation in the northwest region was also abandoned.
Liu Jizhen, an academician of the Chinese Academy of Engineering, said: “Due to the uneven distribution of wind energy resources and the imperfect power grid system, the waste of renewable energy electricity has always been a major problem facing China.”
“More transmission lines should be constructed to make better use of the electricity generated,” he said, citing the report.
China has the world’s largest installed capacity of wind and solar power. However, they only account for 4.9% of the country’s total energy production structure.
The report predicts that wind and solar power installed capacity will continue to grow rapidly in 2017, but more will be located in the eastern and central regions where demand is higher.
It is recommended that new energy power generation projects should not be approved in areas where the wind power waste rate exceeded 10% and the solar power waste rate exceeded 5% in the previous year.
