The hottest summer power consumption peak is appro

The peak of power consumption in summer is approaching, and the national development and Reform Commission requires to increase the proportion of trans provincial transmission of clean energy

the 21st century economic report learned that recently, Hunan, Henan, Anhui, Zhejiang and other places have predicted that there will be a shortage of power consumption this summer, of which Anhui is expected to have a gap of about 2million kW this summer

in this regard, the national development and Reform Commission has deployed. On June 25, the national development and Reform Commission released the notice on ensuring the transportation of coal, electricity, oil and gas during the peak summer in 2018, which pointed out that the regional and temporal tight supply and demand situation still existed during the peak summer this year. The supply and demand in some regions of North China, East China and central China are tight during peak hours, and there may be a power supply gap in some regions

therefore, in the next step, all coal producing regions should organize and guide coal production enterprises to scientifically and evenly organize production on the premise of ensuring safety, continuously improve capacity utilization, and avoid centralized shutdown affecting the stable supply of coal. On the basis of scientific research and judgment of the local supply and demand situation during the peak summer, the lead screw is also directly connected with the 10 prefix, and the 10 prefix moves up and down with the rotation of the lead screw, so as to effectively connect the priority of power generation and purchase, power market trading, trans provincial power transmission and reception and other work. It is imperative to put full efforts to organize production in the first place and do everything possible to improve the power generation and supply capacity during peak hours

power storage gap in some regions

at the 2018 provincial power peak and summer work video conference held on June 25, Xu Wenwen, chief engineer of Anhui Provincial Commission of economy and information technology, said that the maximum power load of Anhui province's dispatching caliber this summer was about 42million kW, and there was a gap of about 2million kW in the balance of power supply and demand. In case of extreme high temperature weather, new units cannot be put into operation on schedule, large units fail to trip, etc., the tension will be aggravated

previously, there were also reports of local power supply gaps in other regions

on June 13, China Henan electric power company held the 2018 summer peak media briefing, which believed that there was basically no standby in Henan Province as a whole, and there was a power supply gap during the peak hours of local heavy loads. During the summer, there was a lack of power supply in northern Zhengzhou, Eastern Zhumadian and Eastern Xinyang. Some bought several large plastic bags at one time, while Xuchang and Kaifeng were in short supply

Shandong electric power company said that due to the impact of the national policy to prevent and resolve the risk of overcapacity in coal and electricity, the construction and commissioning of some units in the province and some supporting power sources outside the province and the transformation of fans were postponed. During the summer, the new power supply capacity was less than the original planning arrangement, and there was a power supply gap of about 5million kW during the peak period of power consumption in summer

in addition, the State Grid Hangzhou power supply company predicts that the maximum power load in Hangzhou in the summer of 2018 is expected to reach 15.7 million KW, and the power supply and consumption of the province is tighter than last year

Bian Zhongqing, director of the power and Energy Department of Anhui Provincial Commission of economy and information technology, pointed out that generally, electricity is not tight, but there is a gap for a period of time because of the peak of electricity consumption in summer. At present, the tertiary industry and residential power consumption are growing rapidly, and the increase of industrial power consumption is also related to summer power consumption

"there is a gap in the electrical load, which only occurs for a short period of time in summer." He said

in terms of industries, the first, second, third and residential power consumption increased by 10.6%, 7.7%, 15.1% and 13.9% year-on-year respectively in August. The contribution rate of secondary power consumption to the growth of power consumption in the whole society was 55.6%, driving the growth of the tensile test volume of power consumption in the whole society by 5.4 percentage points. The power consumption of 28 industries in 31 categories of manufacturing industry increased to varying degrees

the electricity consumption of tertiary industry and residents has achieved a rapid growth of more than double digits. The electricity consumption of some new business forms is not high, but it has increased rapidly. For example, the power consumption of software and information technology service industry increased by 66.05% year-on-year; The power consumption of interconnection and related service industry increased by 63.26% year-on-year, of which the power consumption of interconnection data service industry increased by 207.06% year-on-year

Ouyang Yongxi, former senior engineer of the Policy Research Office of Hunan electric power company, pointed out that the current growth in power consumption is related to the changes in the lifestyle of many residents

for example, in the past, rural areas did not use much electricity, but now they use a lot of household appliances and air conditioners. In addition, rural areas, including irrigation and drainage, need electricity. Fast industrial power consumption is also related to the use of air conditioning facilities in factories. "Therefore, social development and the improvement of living standards will lead to an increase in electricity consumption," he said.

accelerate the development of clean energy

to this end, the national development and Reform Commission issued a notice that the oil cylinder should be lifted and lowered rapidly (see the hydraulic schematic diagram for details) The stable and positive economy has driven the rapid growth of energy demand, and the consumption of coal, electricity, natural gas and other energy varieties has increased significantly

therefore, the regional and temporal tight supply and demand situation still exists during the peak summer. During the peak summer, the demand for power coal increases significantly, and there may be tight supply and demand in some regions and individual periods

the above notice points out that all regions should strengthen the tracking and monitoring of the changes in local economic operation, especially the added value of industries above Designated Size and high energy consuming industries, accurately grasp the changes in market demand, accelerate the improvement of the ability of line transmission of clean energy, strengthen the organization of power transmission, and increase the proportion of clean energy in cross provincial power transmission and reception

Tang Jianwei, chief Macro Analyst of the financial research center of the Bank of communications, pointed out that the power demand is still structural at present, which belongs to the increase in power consumption caused by the high temperature in summer. From a national perspective, there is little possibility of power tension and shortage. "At present, the whole economy is still not very strong in terms of demand, such as downward pressure on investment and consumption, and uncertainty in exports."

the next step is, on the one hand, to strengthen clean energy power generation and promote more and full power generation with clean energy; On the other hand, guide power generation enterprises to strengthen power generation fuel security, do a good job in equipment operation and maintenance, and promote stable power generation and supply

Meng Wei pointed out at the meeting on June 15 that in key areas with severe power supply and demand situation, it is necessary to strengthen the bottom line thinking, make emergency preparedness, and strengthen the plan drill to ensure that when there is a gap between supply and demand, priority is given to ensuring the livelihood of the people and other key power consumption
