In the first half of the year, the power consumption of the whole society increased rapidly, and the national power supply and demand was generally loose

Abstract: at present, the national power supply and demand was generally loose, but under extreme weather conditions, some regions still had tight power supply. We should actively deal with the sudden change of load caused by temperature factors such as high temperature and heat waves, and always put the safe and stable operation of the power system in the first place, prevent large-scale power outages, and give priority to ensuring the demand for production and living electricity

today, the China Electricity Council (hereinafter referred to as "the China Electricity Council") issued the "analysis and forecast report on the national power supply and demand situation in the first half of 2017" in Beijing with appropriate machinery and equipment. The report shows that the power supply and demand in China is generally loose, and some regions have surplus power supply capacity. Among them, the overall balance of power supply and demand in North China; The supply and demand in Central China, East China and South China are generally loose, and some provinces have surplus supply capacity; The northeast and northwest regions have relatively excess power supply capacity. CEC predicts that the growth rate of electricity consumption in the whole society in the second half of the year is slightly higher than 4%, and the year-on-year growth rate is about 5%. Compared with the above, the following upper and lower deviations can be selected to form the overall balance of the year

Ye Chun, deputy director of the Department of industry development and environmental resources of the China electricity Union, said that in the first half of the year, the power consumption of the whole society increased by 6.3% year-on-year compared with the mechanical data testing machine, and the growth rate increased by 3.6 percentage points year-on-year, continuing the rapid growth momentum since the second half of 2016. The power consumption of the secondary industry increased by 6.1% year-on-year, driving the growth of power consumption of the whole society by 4.4 percentage points, which is the main driving force for the growth of power consumption of the whole society

Ye Chun explained that there are four main reasons for the rapid growth of electricity consumption: first, the overall macro-economy continues to be stable and positive, and the growth rate of key indicators such as industrial added value, total retail sales of social consumer goods, infrastructure investment and foreign trade exports has rebounded. Second, the relationship between supply and demand in the industrial products market has improved, market prices have rebounded, and the production situation of enterprises has improved significantly, driving the growth of electricity consumption. Third, new technologies such as high-tech industries and equipment manufacturing industries, as well as new industries and new formats, have developed rapidly, with the rapid growth of electricity consumption, and gradually bred another important force to drive the growth of electricity consumption in the whole society. Fourth, the base of the same period last year is relatively low

in addition, the power consumption of the tertiary industry increased by 9.3% year-on-year, driving the power consumption of the whole society to increase by 1.2 percentage points; The proportion of electricity consumption in the whole society was 13.7%, an increase of 0.4 percentage points year-on-year. Affected by factors such as the high base in the same period of last year and the warmer temperature in the first quarter, residents' domestic power consumption increased by 4.5% year-on-year, the second lowest growth rate in the same period of the past decade with the adoption of high-precision torque sensors

the report shows that in the first half of the year, the power generation of power plants above Designated Size nationwide increased by 6.3% year-on-year; At the end of June, the installed capacity of power plants of 6000 kW and above nationwide was 1.63 billion kw, an increase of 6.9% year-on-year, with sufficient supply capacity. "China's power supply structure and layout continue to be optimized. The newly added non fossil energy power generation installed capacity accounts for 73.4% of the total newly added installed capacity, with a year-on-year increase of 20 percentage points; the newly added wind power and solar power installed capacity in the eastern and central regions account for 57.9% and 76.1% respectively. With the efforts of power enterprises to effectively promote the consumption of new energy, the problem of wind and light abandonment has been alleviated, the average utilization hours of wind power equipment have increased by 67 hours year-on-year, and solar power generation The average utilization hours of electric equipment increased by 39 hours year-on-year. " Ye Chun said

at the same time, the effect of orderly development of coal and electricity is obvious. The investment in coal and electricity decreased by 29.0% year-on-year, and the new installed capacity of coal and electricity decreased by 48.3% year-on-year. However, the national coal supply and demand is tight, the inventory of all links is declining, and the price of power coal is rising at a high level, resulting in a sharp rise in the cost of power coal for coal and power enterprises, and most power generation groups continue to suffer losses in the coal and power sector. "In the second half of the year, we are still worried about the price of power coal." Ye Chun said that with the high price of electricity and coal, the price reduction of electricity in the market transaction is large and the scale continues to expand, and the cost of power generation is difficult to effectively channel outward. It is expected that coal and electricity enterprises will continue to suffer losses, and the production and operation of power generation enterprises will continue to face severe difficulties and challenges

according to the report, if there are continuous and large-scale extreme high temperature weather, lack of hydropower, limited transport capacity and other factors during the peak summer, there may be a shortage of power and coal supply in some areas and parts of the time. "If extreme high temperature weather occurs for a long time and in a wide range, the annual growth rate of power consumption in the whole society may be slightly higher than 5%. It is expected that by the end of 2017, the installed power generation capacity in China will reach about 1.76 billion kw; among them, the installed power generation capacity of non fossil energy will further increase to about 38%." Ye Chun said

in an interview with the media, an Hongguang, Deputy Secretary General of the China Electricity Council, said that the current national power supply and demand is generally loose, but under extreme weather conditions, there is still a tight power supply in some regions. We should actively deal with the sudden change of load caused by temperature factors such as high temperature and heat waves, always put the safe and stable operation of the power system in the first place, prevent large-scale power outages, and give priority to ensuring the power demand for production and living
