Extreme weather is frequent.

Recently, affected by extreme weather, power tensions have occurred in some parts of China. Can the power shortage be resolved by import? Can it be able to relieve the power tension of electricity by regulating electricity prices? How to further improve the energy safety emergency mechanism? China News Agency interviewed a number of industry experts to answer related questions.

Since this summer, Sichuan has faced a huge challenge of high temperature and water shortage. The demand for electricity consumption at high temperatures has increased, and the sharp decrease in precipitation has caused its hydropower power generation capacity to decline, which brings severe tests to power guarantee. As the province of Fengdian in previous years, Sichuan now needs to help other regions.

What is the conveying mechanism between power between power and power shortage areas? Can the power shortage be resolved by increasing import?

Lin Boqiang, the dean of the China Energy Policy Research Institute of Xiamen University, told China News Agency that it is feasible to appropriately expand the input and output of power, but the cost and return of cost and return must be considered.

"Transportation power between different regions must establish infrastructure, which often invests huge capital, and it takes a long time to return to the book. To cope with the extreme weather that occasionally, it will be great The waste of resources is not wise, "he said.

Lin Boqiang further pointed out that import issues are the same. The prerequisite for the two parties to determine the relationship between fixed trade is that there are regular needs. In the absence of frequent demand, it is not realistic that the import transmission is not economical. In fact, electricity is basically defined as non -trading products in economics, and the trading volume is small in reality.

In the case of extreme shortage of electricity, can it relieve the power tension by regulating the electricity price? In Lin Boqiang's view, the method of regulating electricity prices can also work, but it is usually better to take the order of ordering measures such as peaks, avoiding peaks, rotation, and electricity, and the orderly use of electricity can be immediate.

He added that China's power consumption structure determines that the way of ordering is more effective. China's industrial power consumption is very large. Adjusting a small amount of industrial electricity can ensure residents' electricity. In addition, the reform of electricity price is a long -term task. Suddenly changing the electricity price will cause panic people and bring a great impact on the socio -economic. Therefore, in terms of efficiency and consideration of social and economic shocks, orderly use electricity is more suitable than regulating electrical prices.

Yuan Jiahai, a professor at the School of Economics and Management of North China University of Electric Power, said in an interview with China News Agency that in the long run, it is indeed necessary to adjust the supply and demand by the price mechanism. However, the current hard shortage of the hard shortage of Sichuan, it is difficult to make it difficult to adjust by the price mechanism.

"Taking Australia as an example, it has a mature power market. When it encounters a shortage of electricity some time ago, the price of the spot market is up to $ 15 per kWh, and it still cannot form a short -term supply and demand balance. Finally, the market fusion mechanism is launched." Yuan Jiahai said.

"Of course, in terms of flexibility adjustment of electricity prices, how to use electricity prices as a tool for regulating loads need long -term exploration and efforts on this point." Zhou Xiaoxin, an academician of the Chinese Academy of Sciences, added.

"Under extreme weather conditions, the terminal demand increases, and different types of power supply of the supply side will be limited to varying degrees. As the development power supply side of renewable energy is more uncertain under extreme weather conditions." Yuan Jiahai warned, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan warned that Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan, Sichuan warned that Sichuan Sichuan, Sichuan The situation of electricity shortage, the state of the state in the United States, and the European issue last year are all practical cases that affect the safety of power supply by extreme weather. The risk of future risks may be greater.

Extreme weather is frequent, how to further improve the energy safety emergency mechanism to ensure energy supply?

Lin Boqiang said that from a technical perspective, "one more insurance" is not difficult, and one more line can be more guaranteed, but this means huge investment and inaccessible returns.

"The current problem in China is relatively easy to solve. China's power consumption structure determines that as long as the relevant provinces are used in an orderly manner, they can pass the difficulty steadily." Lin Boqiang said, "Unlike China, American residents' electricity consumption consumption is used. It is higher than the industrial power consumption, so once there is a shortage of power, it is difficult to use the orderly electricity to ensure residents' electricity. "

"Of course, assuming that the future extreme climate change is becoming more and more frequent, countries will make more early warning and investment in energy security." Lin Boqiang said.

"This time the power shortage is mainly due to extreme weather. Considering that water and electricity water is periodic, how to deal with similar power shortages is worthy of in -depth research." Zhou Xiaoxin told China News Agency.

Taking Sichuan as an example, Zhou Xiaoxin pointed out that Sichuan can make full use of local natural gas resources and develop gas power generation early to improve the power generation structure. At the same time, some coal power should be retained.

"At present, the proportion of gas power generation in Sichuan is still small. In the long run, if it can further develop gas power generation and cooperate with some coal power, it will greatly improve the toughness of the power system." Zhou Xiaoxin said. (Finish)
