Li Pumin, secretary general of the National Development and Reform Commission, said that it is expected that the power supply will be sufficient this winter and next spring, and the power generation structure will be further optimized. However, considering the factors such as the long-term drought of key hydropower sources, individual regions do not rule out short-term tensions.
Affected by the economic entry into the new normal, China's power consumption growth rate has been declining since 2012. Although the data in 2013 has improved, it has declined again afterwards. The annual growth rate of electricity consumption in 2014 and 2015 was 3.8% and 0.5% respectively.
The situation has changed this year. According to the National Energy Administration, the national total electricity consumption in the first quarter, second quarter, and third quarter increased by 3.2%, 2.1%, and 7.8%, respectively. From January to October, the national total electricity consumption increased by about 4.8% year-on-year. Compared with 4.5% in January-September. The electricity consumption of the first, second and third industries and residents increased by 5.1%, 2.3%, 11.6% and 11.7% respectively, and the growth rate rose by 2.1, 3.3, 4.5 and 7.1 percentage points respectively.
"From the perspective of electricity consumption structure, the contribution rate of the tertiary industry and residents' electricity consumption to the growth of the whole society's electricity consumption continues to be greater than that of the second generation." Li Pumin said that in the three-product electricity market, information transmission, computer services and software industry use electricity growth year-on-year. 15.2%, electricity consumption in the commercial, accommodation and catering industries increased by 9.9% year-on-year, and electricity consumption in the financial, real estate, business and residential services industries increased by 12.6%. In industrial electricity, the negative electricity consumption in the mining industry decreased by 4.8% year-on-year; the electricity consumption in the manufacturing industry increased by 1.6% year-on-year. The growth rate of electricity consumption in the four high-energy-consuming industries was generally low, and the electricity consumption in the steel and non-ferrous industries decreased by 6.5 respectively. % and 1.6%, electricity consumption in the chemical and building materials industries increased by 1.8% and 2.3% respectively.
Judging from the power generation situation, preliminary statistics show that from January to October, the national hydropower, nuclear power and thermal power generation increased by 7.3%, 23% and 1.9% respectively. In terms of power supply support capacity, major hydropower plants nationwide have strengthened water storage since September, and the storage capacity is sufficient. As of the end of October, the total adjustable water power of the national key hydropower plants was 154.68 billion cubic meters, and the total energy storage value was 71.57 billion kWh, an increase of 8.7% and 7.7% respectively.
Li Pumin pointed out that in the first three quarters of this year, the national electricity consumption increased by 4.5% year-on-year, and the growth rate increased by 3.7 percentage points year-on-year. The signs of economic stabilization are showing signs of improvement. Of the 20 manufacturing industries, 18 have achieved positive growth, with 10 of them growing at more than 5%. It is expected that electricity consumption will continue to maintain this momentum in the fourth quarter of this year, and the annual electricity consumption may increase by about 4.5%. As of the end of September, the national power generation installed capacity increased by 10.8% year-on-year, of which, thermal power installed capacity increased by 7.3% year-on-year, and the supply capacity was very abundant.
The China Electricity Council believes that the growth rate of electricity consumption in the whole society will be lower than that in the third quarter in the fourth quarter. The annual electricity consumption of the whole society will increase by about 4.5%. It is estimated that the installed capacity of the new year will be 120 million kilowatts, of which non-fossil energy power generation will increase by 70 million kilowatts. At the end of the year, the national installed capacity of power generation will be 1.64 billion kilowatts, and the proportion of non-fossil energy power generation will be further increased to 36.5%. The country's power supply capacity is generally surplus, and some regions are relatively surplus. During the peak winter season, the supply of coal in some areas may be tight or even tight. It is estimated that the utilization hours of thermal power equipment will be reduced to 4,150 hours in the whole year. In addition, the on-grid price of coal-fired power generation will be lowered, the price of direct electricity transactions by some provinces will be greatly reduced, and the price of coal will rise sharply. The benefits of coal-fired power enterprises will be severely compressed. Some large-scale power generation groups Coal-fired power has suffered an overall loss, and production and operation of enterprises are facing severe difficulties and challenges.
In this regard, Li Pumin said that in response to the uncertainties in the fuel supply, the NDRC has prepared emergency plans for coal-fired power security in key areas, and organized the orderly release of safe, efficient and advanced production capacity. In the next step, coal-fired power companies will be actively encouraged to sign medium- and long-term contracts for coal, so that production and transportation needs to be connected to stabilize market expectations. Further strengthen power demand side management and improve the level of power supply services. In view of the intensified difficulties in peak shaving of power grids, and the contradiction of abandoning water, abandoning wind and abandoning light, comprehensive measures will be taken to improve the peaking capacity of the system, strive to reduce coal-fired power generation, strengthen the consumption of renewable energy power generation, and implement renewable energy regulation. Peak unit priority power generation method, "By adopting various measures, we have the conditions and methods to ensure the stable supply of coal and electricity."
Hydraulic casing power tongs, hydraulic drill pipe power tongs, hydraulic tubing power tongs, hydraulic sucker rod power tongs.
The power tong is an ideal wellhead tool for oil drilling, which is widely used in the threading operation of the pipe string in the offshore and land drilling and workover operations. The use of this pliers can play the role of safety, labor saving and improving work efficiency. This series of pliers is an open type, can freely release the pipe string, and has strong maneuverability; it integrates torque pliers and rotary pliers, and the upper and lower pliers replace cat head, hanging pliers and rotary rope. The power tongs conform to the SY/T5074 standard.
The oil drilling and production wellhead mechanized tools developed by the company have many varieties and complete specifications, and have formed more than 50 series, including ZQ drill pipe power tongs series, TQ casing power tongs series, XSL rotary faucet series, etc., and more than 100 series The product structure of specifications, sales cover all major oil fields in the country as well as Europe, America, the Middle East, Central Asia, Southeast Asia and other regions.

The reporter learned from the National Development and Reform Commission's press conference on the 11th that from January to October, the national total electricity consumption increased by about 4.8% year-on-year, and the growth rate was up by 4 percentage points compared with the same period of last year. The tertiary industry and residents' electricity consumption used electricity for the whole society. The contribution rate of growth continues to be greater than that of secondary production. From the perspective of power generation, nuclear power has grown at the fastest rate, reaching 23%.
