This winter, all parts of the country have experienced the lowest temperature in decades, and the continuous low temperature has brought great challenges to energy supply. 164.31 million kilowatts! On the evening of January 7, the maximum power load of the Central China Power Grid hit a record high in winter for the first time in many years, an increase of 20.7% from the maximum load of last year;

605 million kilowatt hours! On the same day, Shaanxi’s daily electricity consumption exceeded 600 million kWh, an increase of 3.6% from the previous month, which is the tenth record high this winter;

48.2%! As Beijing ushered in the lowest temperature since 1966, the heating electricity load of Beijing residents accounted for nearly half of the electricity load of the Beijing power grid, a record high;

...

The continuously rising power load curve has brought great attention from all parties at home and abroad to my country's energy security supply capacity and level.

What is the current situation of China's energy supply, especially the safe supply of electricity? Under extremely cold weather, what other measures will China's energy and power system take to meet the superimposed needs of energy security for people's livelihood and sustained and stable economic recovery? Tong Guangyi, director of the Electric Power Safety Supervision Department of the National Energy Administration, accepted an exclusive interview.

Take multiple measures to cope with the unexpectedly rapid growth in demand for electricity

Tong Guangyi said that due to multiple rounds of cold wave weather and sustained and stable economic recovery, the country's energy demand, especially electricity demand, has grown faster than expected, and supply and demand in some areas are tight during peak hours. In particular, under the influence of this round of cold wave weather, the country's gas consumption and electricity generation have reached historical highs, and the coal consumption of power plants has also remained high.

In this regard, the National Development and Reform Commission and the National Energy Administration attach great importance to it, give full play to the role of the guarantee day dispatch mechanism with various departments, regions, and enterprises, and adhere to daily follow-up and follow up on the dynamics of power supply and demand in various regions and the supply of primary energy such as thermal coal. , Natural disasters such as low temperature, rain, snow and freezing, and major power safety risks in various regions, etc., work from both sides of supply and demand to protect coal, gas, and electricity.

—— Keep abreast of the dynamics of supply and demand in time to ensure the overall stability of the power supply and demand situation. Tong Guangyi introduced that the National Development and Reform Commission and the National Energy Administration, in conjunction with relevant units, closely monitored and early warnings, strengthened regulation, and maintained the overall balance of supply and demand across the country through measures such as cross-regional and cross-provincial power support. In particular, continue to pay attention to power plants with coal storage levels less than 7 days, and urge relevant units to strengthen coordination to ensure the safety of coal supply and unit operation. "From the current situation, although there is still pressure to guarantee supply in some areas and some time periods, it can generally guarantee the people's electricity demand."

——Respond to natural disasters in a timely manner, and the transmission lines have not been damaged due to disasters. Since the beginning of winter, freezing rain has occurred in some parts of China, which has caused a large area of power lines to be iced. The four provinces (regions) of Yunnan, Guizhou, Guangdong and Guangxi in the south have suffered the most severe icing in recent years, with cumulative icing on lines of 10 kV and above There are more than 6000 lines, and the maximum icing of the line is 38 mm. In response to this, the National Energy Administration actively coordinated power companies to initiate anti-icing preparations in advance, comprehensively strengthened pre-disaster defense, on-duty during disasters, and post-disaster emergency repairs, and promptly carried out line melting and deicing for severely iced lines, ensuring the safety and stability of the power grid Reliable operation and power supply.

-Deal with emergencies in a timely manner to ensure the people's safety and warmth through the winter. Tong Guangyi said that emergency incidents are inevitable in the process of ensuring energy supply. The National Energy Administration requires all units to prepare accident predictions and emergency plans in advance, and arrange special personnel to be on duty 24 hours a day to ensure the first response in case of emergencies. Take Beijing as an example. On January 6, the minimum temperature dropped to -18°C. At 23:08, a thermal power plant in Beijing tripped, reducing its power and heating output. We immediately activated the emergency plan, and while rushing to repair, we organized the heat network to increase heat distribution to ensure the orderly supply of heat during failures. At 4 am, the generator set resumed normal grid-connected operation, and the heating capacity was restored before the city's thermal load peak period, which did not affect the heating demand of the people.

"Judging from the current situation, the national energy supply and demand situation is generally stable, the national power system is operating safely and stably, and the people are guaranteed to use energy." Tong Guangyi said.

Long-term mechanism to continuously strengthen power safety risk management and control

The severe cold weather in winter may continue, and China's economic growth rate has basically returned to the level before the epidemic. It is still important to continue to ensure power supply.

Recently, the foundation of a 500 kV line tower in Hubei was displaced by about 30 cm. The tower was deformed and cracks appeared in the surrounding soil, which endangered the safe operation of the line. After the hidden line hazards were discovered in time, the National Energy Administration dispatched agencies to the site as soon as possible to organize experts to carry out on-site surveys with the company, formulate governance plans, implement emergency preparedness, and effectively control line safety risks.

Timely rectification of hidden dangers is a key link to ensure power safety, and it is also an important measure to ensure energy supply and emphasize "work in peace".

Tong Guangyi said that based on the current situation, the energy system will continue to strictly implement the energy guarantee day meeting mechanism, adhere to daily follow-up and follow-up of the power supply and demand dynamics in various regions and the supply of primary energy such as thermal coal, natural disasters such as low temperature in various regions, rain and snow, and major power Security risk and hidden dangers, etc., will be discussed in the morning and evening meetings to promptly solve the problem of guaranteeing supply and solve problems for the people.

Looking to the long-term, the next step of power supply guarantee work has also been fully prepared. Continue to do a good job in power safety risk management and control, and through the quarterly meeting and weekly reporting mechanism, promptly investigate various hidden risks and take measures to promote solutions. Carry out normal supervision of primary energy for power production, reasonably determine the primary energy reserve margin of load center power generation enterprises, strengthen information sharing with upstream enterprises, and establish a low-level energy early warning and co-processing mechanism. Continue to strengthen the construction of power emergency capacity, strengthen the prevention and response of large-scale power outages, and ensure that the stable and reliable power supply can be guaranteed under extreme conditions.

"The safe supply of electricity is a key link in ensuring energy supply. Without the safety of the power system and the safety of power equipment, the energy demand and heating demand of the people will be difficult to guarantee."

"As an important part of the winter energy supply, the safe supply of electricity is particularly critical. Without the safety of the power system and the safety of power equipment, the energy demand and heating demand of the people will be difficult to guarantee." Tong Guangyi said that in recent years, the National Energy Administration has attached great importance to it. Electric power safety protection work adheres to the basic concept of "safety is technology, safety is management, safety is culture, and safety is responsibility", and has created an electric power safety supervision system that adapts to the new era. One is to rely on technology to ensure safety and use technological innovation to break through bottlenecks. Guide the power industry to maintain power system security and network security through cutting-edge technologies such as "Cloud, Big Things, Mobile Intelligence"; promote the application of advanced safety production results represented by "smart construction sites" and drone inspections; build information platforms such as dam monitoring and early warning , Continuously improve the technology's ability to support safety. The second is to rely on management to improve safety and use a rationalization mechanism to solve problems. Established short-term and long-term, normal and extreme, comprehensive and special "three-in-one" risk management and control mechanism, which manages normalized risks in a quarterly cycle, major system risks in an annual cycle, and major facility risks in a 5-year cycle , Through the implementation of a special action plan to manage and control systemic risks in extreme situations; grasp the three platforms of the Electric Power Safety Committee, the Power Plant and Network Joint Conference, and the Network Joint Conference; straighten out the dam, reliability and quality supervision management system; promote the dispatched agency and Local competent authorities jointly enforce the law and build a "new pattern" of joint management. The third is to rely on culture to promote safety and build consensus with harmony and compliance. Regarding cultural construction as an important starting point for enhancing safety "soft power", the "Guiding Opinions on the Construction of Electricity Safety Culture" was issued, and activities such as the "Electric Safety Culture Construction Year" and "Safety Production Month" were launched to establish self-discipline and continuous Improved long-term mechanism for safety culture construction. The fourth is to rely on responsibilities to control safety, and use powers and responsibilities to compact supervision. A relatively complete legal system that meets the requirements of practice has been formed through the establishment of reforms; the establishment of supervisory interviews, "double random and one open" law enforcement inspections, power safety production information disclosure and sequencing notification systems; on-site inspections and disposals are not in place and hidden dangers Problems such as inadequate rectification and inadequate punishment for interviews have been greatly improved.
