May, the whole country has experienced many rounds of high temperature weather from south to north, "baking in the north and steaming in the south". On July 7, the Central Meteorological Observatory said that in the next few days, Beijing, Tianjin, Hebei, Huanghuaihai and other places will continue to be affected by high temperatures, while the range of high temperatures will also expand, and there will be more high temperatures in the south of the Yangtze River and South China. Under the
continuous high temperature, the electricity load of many provinces and cities has reached a new high. It is reported that the current electricity load in Sichuan, Guangdong, Guangxi, Yunnan, Guizhou and Hainan provinces and regions has reached a record high.
China Electric Power Enterprise Federation predicts that under different climatic conditions, the highest electricity load in China will increase by about 80 million kilowatts to 100 million kilowatts this year. During the summer peak period, the power supply and demand situation in East China, Central China and South China is tight, and there is a power gap; the power supply and demand in North China, Northeast China and Northwest China are basically balanced.
Reporters learned that at present, including Anhui, Sichuan, Chongqing, Guangdong and other places issued energy-saving initiatives.
For example, a few days ago, the Energy Bureau of Anhui Province, the Bureau of Organs Affairs of Anhui Province and the State Grid Anhui Electric Power Co., Ltd. jointly issued the Proposal to Save Electricity for Power Users in the Province. It is proposed that public institutions should take the lead in saving electricity, industrial enterprises should use electricity scientifically, commercial places should use electricity rationally, landscape lighting should be controlled, and residential users should save electricity.
Industrial enterprises should actively cooperate with power dispatching, make full use of the peak-valley time-of-use electricity price policy, rationally adjust production load by means of planned maintenance, shift adjustment and enterprise rotation, actively realize peak-shifting power consumption, and reduce power supply pressure during peak hours. The proposal emphasizes that the start-up of high-energy-consuming equipment should be strictly controlled to avoid no-load operation of equipment, reduce non-production and non-essential power consumption such as air conditioning and lighting, and maximize power conservation.
Cement "Power Limitation Market" can Rise Again?
In the past two years, cement enterprises have been greatly affected by power limitation, which once conveyed to the price situation. According to the analysis of China Cement Network and Cement Big Data Research Institute, the main reason for the nationwide power limitation and continuous soaring cement market in 2021 is the control of energy consumption. Power rationing in 2022 is due to extreme hot weather, which promotes the rapid growth of electricity load, but the scope is small, mostly in Sichuan, Chongqing, Zhejiang and other places. & nbsp; & nbsp;
Recently, the high temperature warning in Sichuan for several consecutive days is somewhat similar to that of last year. From July 8 to 10, Chengdu Meteorological Observatory issued a high temperature orange warning signal for three consecutive days, predicting that the highest temperature in many areas will rise above 35 degrees Celsius in the next 24 hours.
Local media reported that Sichuan Electric Power Company learned from the State Grid that at 13:20 p.m. on July 10, the power load of Sichuan Power Grid reached 59.888 million kilowatts, 788,000 kilowatts higher than highest load of 59.1 million kilowatts last year, a record high.
Since July 11, the whole country has entered the hottest dog days of the year, and this year the dog days are "super-long standby" for 40 days. In
addition, this year's Chengdu Universiade will be held at a time when the Sichuan power grid is facing the peak in summer, and the situation of ensuring the safe and stable operation of power and reliable supply is still grim and complex. It is reported that this year, the power gap in Sichuan Province is about 7.5 million kilowatts, there is a certain gap in electricity, and the regional power situation is tense. Electricity load
in Sichuan Province is rising, and local cement enterprises are facing power rationing and shutdown. A few days ago, China Cement Network learned that many cement enterprises in Sichuan received notifications from relevant departments that the steel and cement industries implemented production regulation from July 5 to August 10, reducing the power load of short-process steel by 60%, and allowing production from 23:00 to 8:00; All cement clinker production enterprises shut down the kiln, reduce 80% of the power load, and the cement mill is allowed to produce at 23: 00-8: 00.
In addition, it is reported that Chongqing is currently organizing a series of special activities for electricity conservation in eight key areas, including industry, commerce, government organs, enterprises and institutions, transportation, health, education, urban and rural construction, and community residents, to promote and implement various good measures and methods for electricity conservation. In terms of
cement, Chongqing Economic and Information Commission recently issued the "Notice on Issuing the Work Program of Power Staggered Peak Production in Cement and Other Industries in Summer". According to the characteristics of the industry, during the period from 00:00 on July 1, 2023 to 24:00 on August 31, 2023, cement clinker enterprises are required to stagger the production peak of 46 clinker production lines of 31 enterprises for no less than 30 days on average, and cement mills shall stagger the production peak. A cement enterprise
in Sichuan told China Cement Network that if the above-mentioned notice of power limitation and kiln shutdown is implemented in place, it will inevitably have a more obvious impact on the cement market situation. & nbsp;
How to protect the power supply?
At present, the power grid load in many provinces has reached a new high, how to ensure the power supply?
Recently, the National Development and Reform Commission spokesman Meng Wei responded, will focus on five aspects of work:
to promote the construction of various power projects;
to strengthen the fuel supply guarantee, to ensure the peak power generation needs of coal and high calorific value coal, gas and hydropower storage;
Promote all kinds of generating units to be fully developed. Ensure that the output level of thermal power in peak hours is better than that in normal years, optimize the dispatching of reservoir group to improve the peak power generation capacity of hydropower, promote the multiple use of wind power, solar power and nuclear power, and
do a good job in the optimal dispatching of national power grid operation. We will strengthen cross-grid mutual aid, ensure power supply in key areas and important periods, and
manage power demand side. We should attach equal importance to increasing revenue and reducing expenditure, and ensure the safety and stability of people's livelihood and key electricity consumption.
