Drought in Yunnan affects power supply, Guangdong, a major economic province, faces a power gap | Cross-strait | Central News Agency CNA

(Central News Agency reporter Wu Baiwei, Shanghai, 30th) The drought problem in Yunnan, a major hydropower province in southwest China, has not been solved, which will affect the efficiency of hydropower generation. Guangdong, a major power consumer province, gets 1/3 of its electricity from Yunnan, of which hydropower accounts for the majority. It is about to enter the peak of electricity consumption in summer and may be the first to face power shortages.

According to the Daily Economic News and Hong Kong Economic Daily, Yunnan has been facing drought problems since the beginning of this year. Even though the first four months of this year were relatively dry, sufficient rainfall was not expected in May. At present, relevant local units predict that even in early June, there is no effective rainfall in most areas of Yunnan Province, and local droughts will continue, which will have a greater impact on agricultural planting and power supply.

While Yunnan is facing a severe power supply situation, the volume of discussions on “what to do in Guangdong” has gradually increased.

The report pointed out that in China’s “West to East Power Transmission” project, Yunnan and Guangdong are the largest power transmitters and power consumers in the Southern Power Grid system. According to data from Tianfeng Securities, in the power supply structure of Guangdong Province in 2022, the electricity sent from Yunnan to Guangdong accounted for 68.92% of Guangdong’s external power consumption, accounting for 16.03% of Guangdong’s total power generation and power consumption. From June to August this year, Guangdong is about to face a seasonal peak of electricity consumption, and the power shortage in Yunnan may exacerbate the problem of electricity consumption in Guangdong.

The report mentioned that Guangdong is the largest province in China’s economy, and its electricity consumption has always been among the top in the country. In 2022, Guangdong’s electricity consumption will reach 787 billion kWh, ranking first in the country. Under the huge demand for electricity, Guangdong’s power generation capacity is also considerable, reaching 610.22 billion kwh, second only to Inner Mongolia and ranking second in the country.

Nevertheless, Guangdong is still one of the provinces with the largest power shortage in China. If only the “net contribution rate of power generation” in 2022 is used, Guangdong will be negative 176.8 billion kilowatts.

Guangdong’s economic growth depends on the support of electricity. It is currently estimated that by 2025, the electricity consumption of the whole society in Guangdong will reach about 880 billion kilowatts, and it is imperative to increase investment. However, from the perspective of investment structure, it is difficult to realize the increased production capacity quickly under the existing conditions.

Lin Boqiang, dean of the China Energy Policy Research Institute of Xiamen University, mentioned in the report that Guangdong’s local power generation is still highly dependent on thermal power generation, and natural gas, coal and other resources rely on external supplies, while the proportion of wind power and solar power generation is still small, and they are easily affected. Due to space and weather factors, in Guangdong where there is insufficient space, it is difficult to become more stable power than the existing power supply mode.

He believes that the future development of new energy power generation models in Guangdong will still rely on power transmission from other provinces. At present, only the Gobi environment in the northwest can meet Guangdong’s electricity demand, and this will involve the planning of large-scale projects, including power grid transformation.
