China's Clean Energy Consumption Continuously Improved in the First Quarter
Sitting at my home in Hunan, I used solar energy from Gansu to generate electricity. Wind power from the three northeastern provinces, through Tongliao in Inner Mongolia, instantly lit up thousands of lights in Shandong. With the growth of trans-provincial and trans-regional transportation of clean energy, China's "abandonment of wind" and "abandonment of light" have improved significantly since this year.
Take the data released by the State Grid Corporation on the 11th as an example. In the first quarter, the new energy generating capacity in the company's operating area reached 115.8 billion kilowatt hours, up 10% year on year. New energy power generation accounted for 9.1%, up 0.7 percentage points year on year. Waste electricity from new energy sources reached 4.66 billion kilowatt-hours, down 31% year-on-year. The electricity rejection rate was 3.9%, down 2.1 percentage points from the same period of last year, and maintained the good trend of "Shuang Sheng and Double Decline".
According to Liu Jinsong, deputy director of the State Grid Development Department, in recent years, the State Grid has continued to strengthen the construction of new energy grid connection and transmission projects, and has built a number of long-distance ultra-high voltage transmission lines, further improving the power grid's ability to optimize the allocation of large-scale resources. At the same time, through continuously improving the real-time balance monitoring and dispatching of the power grid and continuously expanding the trading scale of the clean energy market, the clean energy consumption has achieved remarkable results.
It is understood that the clean energy that needs to be absorbed at present is not only hydropower in the southwest region and large-scale photovoltaic and wind power installations in the "three northern" regions, but also distributed photovoltaic power generation across the country, especially photovoltaic poverty alleviation projects scattered among households in remote rural areas. By the end of 2018, the national grid had a cumulative grid-connected capacity of 47.01 million kilowatts of distributed photovoltaic power generation, an increase of 67% over the end of 2017.
"It is suggested that all localities should reasonably determine the scale, layout and timing of clean energy construction in accordance with the consumption target and in combination with their own conditions and capabilities." Liu Jinsong said that although it is very difficult to absorb, power grid enterprises will continue to take more measures and improve the utilization rate of new energy.
He said that in 2019, the State Grid will speed up the construction of transmission channels such as Zhang Bei-Xiong 'an UHV AC, Qinghai-Henan, Yazhong-Jiangxi, North Shaanxi-Wuhan UHV DC, and Zhang Bei flexible DC. At the same time, a variety of market-oriented trading methods will be adopted to promote the consumption of clean energy and strive to achieve more than 70 billion kilowatt-hours of inter-provincial trading of new energy. Vigorously promote electricity substitution, improve electricity consumption, and strive to complete the substitution of more than 145 billion kilowatt hours of electricity.
