Sun Xupeng, a 50-year-old loader, operates the joystick, several gates are immediately opened, and the coal that has just left the warehouse is automatically loaded into a train car through the train rapid loading system. In an hour, a coal-filled train will reach the Tianji power plant 28 kilometers away, providing a steady stream of electricity to Shanghai, Zhejiang and Jiangsu.
Located in the Dingji Coal Mine in Huainan City, Anhui Province, central China, Sun Xupeng, who has been working on trucks for 10 years, is busier than in previous years.
"In October, we sent five or six trains a day, loaded with coal, and the average daily coal production reached 15,000 tons, an increase of 20% over the previous three quarters." Sun Xupeng said that sometimes late at night, coal is still being loaded and shipped.
Affected by multiple factors such as the continuous recovery of economic operation and the rapid growth of electricity consumption, after the autumn of this year, the energy supply in some parts of China is facing a test, especially the supply and demand of coal continues to be tight, and the power supply is once affected.
"We are taking every step to secure the supply of coal and fully exploit the capacity of the stope to increase both production and quality." Li Ming, secretary of the party committee of the Dingji coal mine, said.
Jing Jian, deputy director of the Safety Basic Department of the State Mine Safety Supervision Bureau, said a few days ago that 153 coal mines that meet the conditions for safe production and supply have been audited and screened to be included in the emergency supply guarantee list, included in the fast track of capacity increase, which can increase production capacity by 220 million tons / year, and it is expected to increase coal production by 55 million tons in the fourth quarter.
Data show that on October 18, China's daily coal production has exceeded 11.6 million tons, a new high this year; the national unified dispatch power plant has nearly 88 million tons of coal, an increase of more than 9 million tons over the beginning of the month.
On the one hand, we will release high-quality production capacity to ensure the safe and stable supply of energy; on the other hand, we will take into account the comprehensive implementation of various aspects to achieve the goal of "double carbon". China is responding to this energy supply "big test" with systematic, coordinated thinking, and more detailed and concrete actions.

Zhao Chenxin, secretary general of the National Development and Reform Commission, said at the State Council's regular policy briefing that "energy supply can be guaranteed this winter and next spring." At the same time, he stressed that China's release of advanced coal production capacity is promoted in accordance with market-oriented and law-based methods, and all the coal mines released are legal and compliant.
"We will ensure that the carbon peak and carbon neutrality targets are achieved on schedule while securing domestic energy supplies." Zhao Chenxin said.
Sun Xupeng's Dingji Coal Mine and Tianji Power Plant belong to Huaihu Coal and Power Co., Ltd., which is one of the earliest coal power enterprises in China to carry out integrated "joint ventures". Continuous technical transformation of the unit has reduced the coal consumption of the second phase of the Tianji Power Plant to 278 g/kWh, and the daily average of the emissions of soot, sulfur dioxide and nitrogen oxides has reached the requirements of the ultra-net index.
"Right now, we still have a balance on our carbon target." Chen Wei, deputy director of Tianji Power Plant, said that the thermal power plant began to "concurrently" generate photovoltaics, and its distributed photovoltaic power station has reached an average annual power generation capacity of 7 million kWh, and will invest in new energy projects nationwide in the future to achieve green and low-carbon development.
In the Zhuxianzhuang Coal Mine under Huaibei Mining (Group) Co., Ltd., coalbed methane is used for power generation heating or underground refrigeration; solid waste coal gangue is recycled for burning bricks, so that the gangue does not leave the mine and is not discharged; it is planned to invest in intelligent gangue sorting system to improve coal screening efficiency and resource recovery rate...
"Full production to ensure the supply of coal does not affect the promotion of energy conservation and emission reduction, and various technological transformations are helping to improve coal recovery and utilization rate, and achieve environmentally friendly production and intelligent production." Liu Wensheng, secretary of the party committee of the Zhuxianzhuang coal mine, said.
On the surface of the 6,000 mu of panji coal mining subsidence area about 200 kilometers away from the Zhuxianzhuang coal mine, the floating photovoltaic power station with a total installed capacity of 150 megawatts of water surface quietly absorbs solar energy, and the upper power generation, lower aquaculture, and the mining area that sinks due to resource depletion is once again "lit up" by photovoltaics.

At present, more than 80% of the world's greenhouse gas emissions such as carbon dioxide come from the use of fossil energy, and clean energy sources such as wind and light are considered to be the main force to replace fossil energy. According to the plan, by 2030, the proportion of non-fossil energy in Primary Energy Consumption in China will reach about 25%.
At the 15th Conference of the Parties to the Convention on Biological Diversity Leaders' Summit held in Kunming, China proposed to continue to promote the adjustment of industrial structure and energy structure, vigorously develop renewable energy, and accelerate the planning and construction of large-scale wind power photovoltaic base projects in desert, Gobi and desert areas.
On the supply side, promote technological transformation, energy conservation and emission reduction, and amplify the substitution role of non-fossil energy; on the demand side, China pays attention to the use of market-oriented methods to adjust the unreasonable demand of high-energy-consuming industries, forcing changes in energy consumption habits and utilization efficiency.
China's National Development and Reform Commission recently issued a notice on further deepening the market-oriented reform of coal-fired power generation feed-in tariffs, which clearly states that the proportion of coal-fired power generation sold through the market will be increased to 100%, and at the same time, the scope of fluctuations in the transaction price of coal-fired power generation market will be expanded to no more than 20% in principle, and the market transaction price of high-energy-consuming enterprises will not be limited to 20%.
Peng Shaozong, deputy director of the Price Department of the National Development and Reform Commission and a first-level inspector, said that this is conducive to making electricity prices more flexible to reflect the power supply and demand situation and cost changes, curbing unreasonable electricity consumption, promoting high-energy-consuming enterprises to increase investment in technological transformation, improving energy utilization efficiency, and promoting industrial structure transformation and upgrading.
People in the industry generally expect that the tight energy supply is staged, and with the implementation of relevant measures such as supply assurance and price stabilization, the tight supply of coal and electricity will be alleviated.
In 2020, Huaihu coal power will transmit 11.9 billion kWh of electricity to Shanghai, Zhejiang and Suzhou, about two-thirds of which will be sent to Shanghai; as of October 19 this year, 10.4 billion kWh of electricity has been generated, and it is expected to generate 12.7 billion kWh of electricity in the whole year.
"The lack of coal supply is a phased problem, but the efforts to achieve the 'double carbon' goal, develop clean energy, and promote energy conservation and emission reduction are non-stop." Wang Xiaobo, chairman of Huaihu Coal and Power Co., Ltd., said.
