In response to the most serious power shortage that may have occurred since 2004 this year, the State Grid Corporation of China, a large-scale central enterprise that supplies electricity to 26 provinces, promised on the 23rd that it will actively take measures to ensure the orderly supply of electricity and give priority to guaranteeing residents’ lives, hospitals, and Schools and other important users of electricity that involve public interest and national security.
At the State Grid Corporation of China held a video conference for the peak summer production safety, Tan Rongzhen, director of the State Electricity Regulatory Commission, said that in June the country will enter the peak of electricity consumption, and it is expected that the nation's largest power shortage will reach around 30 million kilowatts during peak hours. He disclosed that from January to April, the situation of power cuts in some areas was severe, and coal shortages were shut down in some places. The nation's largest daily coal shortage was 9.8 million kilowatts, which is equivalent to a Chongqing power generation capacity.
“This year is the most intense power supply and demand situation in recent years. The total power gap may exceed the worst in history in 2004.†Shuai Junqing, deputy general manager of State Grid Corporation of China, predicts that only State Grid will be responsible for 26 provinces The power gap will reach about 30 million kilowatts, among which 10 power grids in Beijing, Tianjin, Tangshan, Hebei, Shanghai, Jiangsu, Zhejiang, Anhui, Hunan, Henan, Jiangxi, and Chongqing will have a tight supply and demand situation.
He further predicted that if the situation is intensified, the power gap will reach about 40 million kilowatts. “Currently, some provinces in East China and Central China have started to restrict the production of electricity for industrial users, and the scale of production-restricted electricity production will be further expanded during the summer peak season.â€
Shuai Junqing analyzed that the reasons for this lack of electricity were changed from the single factor of insufficient “supply of coal†to the “insufficiency of power coal supply and insufficient power generation in local areas, insufficient capacity of cross-regional grid transmission†and other factors, and in the short term Difficult to change. In addition, extreme weather such as thunderstorms in summer and large-scale wind power access will also increase the risk of safe electricity production.
The four large-scale off-grid incidents of wind farms that have occurred since this year have affected the security of the power grid. Shuai Junqing warned that if a large number of fans retreat from the network at the same time during the summer, it will not only cause loss of power generation output, increase power supply and demand, but also may cause chain reaction, which will have a serious impact on the safety and stability of the power grid.
In response to the severe power consumption situation this summer, the State Grid promised to give full play to the role of large-scale power grid resource allocation and demand-side power management, ensure the orderly supply of electricity, and resolutely prevent large-scale blackouts and large-scale power outages. Ensure the safe and stable operation of the power grid, ensure reliable power supply for key cities and important users, ensure that urban and rural residents can use electricity to meet the needs of the entire society.
Shuaijun Qing said that the State Grid will strictly control "two high" enterprises and industries with excess capacity to use electricity to reduce unreasonable demand for electricity. Cooperate with the local government to improve the peak-to-peak electricity price, strictly implement the differential electricity price of high-energy-consuming industries, and increase the adjustment of price leverage.
He said that in accordance with the principle of “limited guarantees,†it will formulate a comprehensive program for orderly use of electricity, so that “power cuts will not be blocked,†and priority will be given to ensuring that residents’ lives, hospitals, schools, etc. are related to public interest and national security. Users use electricity.
