40 ° C fire umbrella high -tension electricity climb more enterprises to make electricity in the people

Since August, extreme high -temperature weather in many places across the country has continued, and "40 ° C cannot enter the national high temperature rankings" has once rushed on the hot search.

Extremely high temperature weather drives the soaring power load. In order to ensure the smooth operation of the power grid system and ensure residents' power consumption, Sichuan, Jiangsu, Zhejiang, Anhui and other places have successively launched an orderly power consumption model, advocating saving electricity, and requiring industrial enterprises to produce "to let the people".

On the morning of August 15th, the Central Meteorological Observatory continued to issue a high-temperature red warning. It is expected that the high temperature weather in East China, Central China, and some areas of Xinjiang that day will continue. The highest temperature will be 35-39 ° C. The maximum temperature of other places can reach above 40 ° C.

Although it is close to the end of summer, the meteorological department is expected to continue in high temperature weather in many places, and the power guarantee in high temperature areas will be tested.

Start the "Order Electricity" mode in many places

Since the summer in June this year, high -temperature weather in many places across the country has led to continuously rising electricity loads. Shandong Grid, Henan Power Grid, Ningxia Power Grid, Jiangsu Power Grid and other electricity loads in the operating area of ​​the State Grid have reached a record high.

Since August, high -temperature weather above 35 ° C and even 40 ° C frequently appeared in Zhejiang, Jiangsu, Anhui, Sichuan and other places. The peak load of local power demand has continued to rise, bringing challenges to local power guarantee work.

On the afternoon of August 15th, the Jiangsu Meteorological Observatory issued a notice saying that Yixing's temperature rose to 42 ° C and once again refreshing the highest temperature record in Jiangsu.

At the peak of Jiangsu Province held on August 10 at the scene of the summer energy insurance for on -site dispatching video, Li Kanzhen, director of the Jiangsu Provincial Development and Reform Commission, pointed out that the high temperature weather duration in this round of high temperatures is long and high. To create a record high, the province's development and reform system must make every effort to ensure the protection of energy and electricity scheduling; all districts and cities must comprehensively use multiple demand -side management methods to ensure the safety of power supply.

According to the introduction of State Grid Zhejiang Electricity, Meng Gang, director of the Zhejiang Provincial Development and Reform Commission, pointed out when he went to the State Grid Zhejiang Electric Power investigation on August 7th that it is necessary to do a good job of supplying and stable prices, establishing and improving the research and judgment mechanism of outsourcing electricity. In other ways, reduce the pressure of the grid and ensure that this round of peaks will be carried out in the summer.

Recently, the energy departments of Zhejiang, Anhui, Jiangsu, Hubei and other places, the Economic and Society of Economic and Information Technology, and the local branch of the State Grid have successively issued an initiative to save electricity consumption, calling on each electricity unit to save electricity and use it. Methods and other methods of rotation to allow electricity to actively support the power supply pressure during the peak period of electricity usage.

Sichuan expanded enterprises to "let electricity in the people" scope

Sichuan Province, which is also in high temperature weather, has taken the lead in expanding the scope of implementation of industrial enterprises "to let the people".

A document circulated locally shows that on August 14, the Sichuan Provincial Department of Economics and Information Technology and State Grid Sichuan Electric Power Company jointly issued the "Urgent Notice on Expanding Industrial Enterprises to Enable the People in the People". As the current situation of power supply and demand is further intensified, in order to ensure the safety of the Sichuan power grid, to ensure people's livelihood power, and to ensure that there is no power -to -line power limit, the local area will cancel the response of active mistakes and avoid peak demand, and expand the scope of the implementation of industrial enterprises to enable the people.

Specifically, from August 15th, 19 cities (states) in Sichuan Province (except Panzhihua and Liangshan) expanded industrial enterprises to implement the scope of the implementation of electricity in the people; The white list is a key guarantee enterprise) to implement the full -stop production (except the security load), put high temperature leave, and let the electricity be on the people. The time starts from 00:00 on August 15th to 24:00 on August 20.

The Sichuan Meteorological Observatory issued a high-temperature orange warning on August 14. It is expected that from August 15-19, the maximum temperature in most places in Sichuan Basin can reach 35 ° C -39 ° C. above.

The expansion of orderly use measures has also had a certain impact on the production and operation of local enterprises.

On August 15th, the relevant person in Tongwei shares told the 21st Century Business Herald reporter that the power outage plan is still communicating. At present, it is actively cooperating with relevant departments to adjust the load in an orderly manner. As the subsequent power situation is effectively alleviated, the company's electricity consumption will return to the recovery until normal level. Another person from another photovoltaic enterprise responded that production projects are currently operating at low load.

Some photovoltaic companies also told the 21st Century Business Herald that the orderly use measures have little impact on the production of project production in Sichuan.

Guoguang (002749.SZ) announced on August 15 that due to the stress of power supply, the company's wholly -owned subsidiary Runier Technology will be temporarily suspended from 0:00 on August 15th to 24:00 on August 20. Guoguang said that other production bases in the company are in normal production status, and the temporary suspension of Runer Technology will not have a significant adverse effect on the company's operating performance.

Zhongfu Industrial (600595.SH) announced on August 14 that some of the company's two subsidiaries have discontinued production from August 14th for a week, and it is expected to reduce the output of electrolytic aluminum a total of 12,900 tons. Luotianhua (000912.SZ) also said that the production device of the company's Luzhou Naxi District will also be discontinued from August 15th to 20th, which is expected to reduce the output of 35,000 tons and 10,000 tons of methanol.

Requirement side response to peak load

Sichuan is a large hydropower province and a large power province. At the same time, it also undertakes the task of west power. Recently, the water and electricity forces are less water and upstream in high temperature weather. Hydropower is also affected. Zeng Ming, a professor at North China Electric Power University and director of the Energy Internet Research Center, told reporters of the 21st Century Business Herald that under the high temperature weather that has not been encountered for many years, the peak load of the local power grid of Sichuan has increased rapidly, the grid load peak valley is rapidly widened, and the limited hydropower is limited The adjustment ability cannot completely make up for the peak difference, and ultimately leads to the expansion of the scope of the orderly electricity in order to ensure the stability of the power grid system.

Judging from the trend in recent years, the sustainable economic development has driven the demand for electricity, and the difference between the peak and valley of urban power grid has gradually expanded, and extreme weather has exacerbated this trend. At the peak period of electricity, power supply and demand is tightly balanced, and the order -oriented power consumption mode is becoming more and more common.

The "Analysis Report of the National Power Supply and demand situation in the first half of 2022 in the first half of 2022" released by the China Electric Power Enterprise Federation pointed out that during the peak summer, the national power supply and demand was generally balanced. Supply and demand is tight, and power supply and demand in North China, Northeast and Northwest China is basically balanced.

According to the latest data, domestic power production and social power consumption have maintained rapid growth. According to the data of the National Bureau of Statistics, in July this year, the growth rate of domestic power production accelerated. A total of 805.9 billion kilowatt -hours of electricity was generated in the month, a year -on -year increase of 4.0%. Solar power generation has accelerated.

According to data from the National Energy Administration, in July, the total electricity consumption of the whole society was 832.4 billion kilowatt -hours, a year -on -year increase of 6.3%; in terms of industries, the electricity consumption of the primary industry was 12.1 billion kilowatt -hours, an increase of 14.3%year -on -year; 513.2 billion kWh, a decrease of 0.1%year -on -year; the electricity consumption of the tertiary industry was 159.1 billion kilowatt -hours, an increase of 11.5%year -on -year.

Zeng Ming pointed out that in the future, the pairing of electricity peaks will become larger and larger, but the time period of the peak time is not long. It is not cost -effective to expand the power production capacity of a large number of peaks, which will lead to the utilization rate of installation capacity, which will cause the installation capacity. The utilization rate of the power plant and the line utilization of the power grid are low. Therefore, it is necessary to use the order of ordering to mobilize the response capacity of the demand side to adjust the grid peak valley through market mechanism, price mechanism, and administrative means.

In addition, the renewable energy and traditional energy sources within and between in various areas must also be coordinated in terms of planning, marketing, and running dispatch. The total power of power occurs, but due to poor coordination, there is a problem of supply.
