Compared with the previous cold wave, the first cold wave of the Year of the Dragon cooled down greatly, the low temperature lasted longer, the freezing rain affected a wider area, and the rainfall in the south was stronger. The demand for heating and power supply has risen in many places. The coal, electricity, gas and other energy industries have actively responded and produced intensively around the clock to ensure the best of the best.
Stable and reliable power**.
On the shore of the Yellow Sea, in the Haiyang Nuclear Power Plant in Shandong Province, nearly 1,000 employees have been sticking to their posts for several days to ensure the safe operation of the Haiyang nuclear power unit and the "Nuanhe No. 1" nuclear energy heating project. At present, the two million-kilowatt units of Haiyang Nuclear Power Plant have generated more than 100 billion kilowatt-hours of electricity, adding "green" to the warmth and supply.
On January 23, in Gaogang Village, Nanjing County, Zhangzhou City, Fujian Province, the staff of the Chuanchang Town Power Supply Station of the State Grid Nanjing County Power Supply Company used infrared thermometers to detect the condition of the equipment. (Photo by Lai Weifeng).
Electricity is the "lifeline" to keep warm and secure. It is expected that from February 20 to 26, there will be icing of power lines in Hubei, Hunan, Henan and other places. The State Grid said that the power in the business area is generally stable, safe and reliable.
On the evening of February 20, Tacheng, Xinjiang, was affected by a strong cold wave, and the minimum temperature dropped to minus 35 degrees Celsius. State Grid Tacheng Power Supply Company organized staff to walk through the snowstorm to inspect the oil temperature and oil level of the transformer and check the hidden dangers of equipment failure.
State Grid Hubei Electric Power uses visualization equipment to monitor 78 lines, conduct infrared general testing of substations, and organize more than 1,000 emergency teams, more than 1,300 emergency vehicles, and more than 1,500 generators to be on standby at any time to prepare for emergency repair.
China Southern Power Grid is in good order. Affected by a new round of cold waves, the temperature in the south will drop by 14 to 20 degrees Celsius from north to south. China Southern Power Grid issued a yellow warning for low temperature, rain, snow and ice to prevent and respond to disasters.
It is expected that the maximum load of China Southern Power Grid will reach 17.1 billion kilowatts, an increase of 8% year-on-year. Zhang Qiang, director of the power dispatching and control center of China Southern Power Grid, said that China Southern Power Grid will adjust the power balance and consumption strategy in a timely manner, keep an eye on coal production and real-time dynamics of thermal coal, and ensure that thermal power units can withstand the peak of electricity consumption.
Coal production is in full swing.
On the evening of February 20, at the Huaneng Xigu Thermal Power Plant in Lanzhou, Gansu Province, Sun Kai, an employee who had just finished dealing with the failure of the coal sampler, returned to the dormitory not long after, and ** rang again.

The No. 2 dumper cannot be flipped over, and the speed will be processed. "* There's a new mission coming from the other end.
Sun Kai put down the dumplings in his hand that he hadn't had time to eat, immediately put on his overalls, and rushed to the scene with a toolkit on his back. Check the drawings, check the route ......Sun Kai kept going back and forth between the power distribution room and the operation room. After more than 1 hour of hard work, the fault was eliminated, and a truckload of coal was successfully turned into the coal hopper.
As the largest electric power and heat production enterprise in Gansu, in order to ensure the supply of electricity and heat, all 20 heating units of Huaneng Gansu Company are in operation, with a daily power generation of about 14.5 billion kWh, with a daily heat supply of nearly 300,000 gigajoules, and more than 20 days of thermal coal inventory available. The company strengthens the inspection of key equipment, does a good job of fuel reserves and equipment in advance, and ensures the peak capacity of main and auxiliary equipment.
To keep warm and supply, coal is the "ballast stone". Coal is the "ration" of coal-fired power and heating units, and coal-fired power is needed to ensure the peak energy consumption in winter.
In Ordos, Inner Mongolia, the fully mechanized mining face of the Shendong Shangwan Coal Mine of the National Energy Group, sharp picks pierced into the coal seam, and 80 centimeters thick hard coal fell like dirt, and the coal produced will be loaded into the train with the coal conveyor belt and continuously transported to all parts of the country.
In the dispatching and command center of Zhunneng Group of the National Energy Group, all dispatching personnel on duty are on duty to ensure 24-hour uninterrupted production. Under their command and dispatch, the mining and stripping plan has been continuously optimized, and all links such as coal mining, washing and processing, loading and transportation have worked together to ensure that the two coal mines under the group produce nearly 180,000 tons of coal per day, sending warmth to thousands of households.
As the world's largest coal producer, from February 10 to 20, China Energy Group's self-produced coal output reached 1,85030,000 tons. At the national level, according to the statistics of the China Electricity Council, as of February 20, the number of available days of coal inventory in power plants was 20 days, and the coal reserves were sufficient.
Consolidate the clean heating source.
PetroChina has taken multiple measures to increase production and ensure supply, stand on a good post and supply good gas.

The resource side is at full throttle. More than 20,000 gas wells in the main gas fields of PetroChina Changqing Oilfield, such as Jingbian, Yulin and Sulige, are operating at full capacity and full capacity. All gas production units have strengthened 24-hour on-duty scheduling and monitoring to ensure a safe, stable and full supply of gas to the large pipeline network of the Shaanxi-Beijing Line and the surrounding areas.
As the main source of natural gas for the West-East Gas Pipeline, the Tarim Oilfield produces an average of 97.5 million cubic meters of natural gas per day, and more than 30,000 cadres and employees are stationed in the desert Gobi to ensure the balance of upstream and downstream production and sales and safe production.
The adjustment side is continuously optimized. PetroChina's Hutubi gas storage in Xinjiang Oilfield has done a good job of equipment insulation and emergency plans in advance, and improved the capacity of gas storage for peak regulation and supply guarantee through measures such as fine management of one well and one policy.
The Liaohe Oilfield Gas Storage Group shoulders the important task of ensuring supply in 7 provinces including Beijing, Tianjin and Hebei, and continues to play the role of natural gas peak regulation and supply.
Since February 19, Sinopec has made every effort to respond to the changes in market demand in key areas such as Hebei, Henan and Shandong in accordance with the principle of "ensuring people's livelihood, public utilities and key points", and has increased the supply of natural gas to six northern provinces by more than 29 million cubic meters, giving priority to meeting the heating and domestic gas needs of residents in the supplied areas.
The State Pipeline Network Group inspected the oil and gas transmission equipment and facilities in the station, strengthened the linkage of production, scheduling and emergency duty, patrolled the oil and gas pipelines in the face of wind and snow, strengthened the prevention measures of ice blockage in the station and pipelines, and made every effort to ensure the safe and stable operation of the oil and gas pipelines and reliable energy.
