By 2030, strive to form a dispatchable production capacity reserve of about 300 million tons/year——

As the proportion of clean energy increases, why should we build coal production capacity reserves?

Recently, the China Development and Reform Commission and the China Energy Administration issued the “Implementation Opinions on Establishing a Coal Capacity Reserve System” (hereinafter referred to as the “Implementation Opinions”). It is proposed to initially establish a coal production capacity reserve system by 2027. The construction of a number of coal mine projects with capacity reserves has been approved in an orderly manner to form a dispatchable capacity reserve of a certain scale.

Against the background that China is orderly advancing green and low-carbon transformation and the proportion of clean energy continues to rise, why is it necessary to establish a coal production capacity reserve mechanism? Guide enterprises to establish coal production capacity reserves. How to do this?

Give full play to the role of coal as “ballast” and “stabilizer”

In Hulunbuir City, Inner Mongolia Autonomous Region, when I walked into the operation site of Baorixile open-pit coal mine of China Energy Group Yanbao Energy, shovels and trucks were busy non-stop, and the coal crusher was operating efficiently. From coal mining, coal transportation, crushing to coal storage, coal loading and transportation, the operation site is coordinated in an orderly manner and completed in one go. Here, 100,000 tons of coal are transported to the northeast along the railway every day.

As an important force in ensuring coal supply in eastern Inner Mongolia and the three northeastern provinces, Yanbao Energy’s Baorixile open-pit coal mine adopts a centralized depth reduction and stripping method to achieve rapid coal exposure, maximize equipment efficiency, and provide a solid guarantee for energy supply in the Northeast region.

Coal is China’s main energy source and plays a “ballast” and “stabilizer” role in ensuring energy supply. From the perspective of China’s energy production landscape, China’s national conditions are “rich in coal, poor in oil and little gas”. To consolidate the foundation of domestic energy production, the security of coal supply must be ensured.

In recent years, China’s high-quality economic development has been solidly promoted, and energy consumption has maintained rapid growth. Coupled with the impact of extreme weather and other uncertain factors, coal supply is tight in some areas and during certain periods.

A certain scale of coal reserve capacity will be built to enable upward elastic production in extreme situations such as violent fluctuations in the international energy market, frequent severe weather, and drastic changes in supply and demand. Quickly release reserve production capacity, effectively improve coal emergency support capabilities, and better play the role of back-up protection in coal energy supply.

The “Implementation Opinions” propose that we should proactively adapt to changes in the coal supply and demand situation, form stable production capacity reserve support policy expectations, and actively guide qualified enterprises to build coal reserve production capacity. By 2027, a coal production capacity reserve system will be initially established, and the construction of a number of production capacity reserve coal mine projects will be approved in an orderly manner to form a dispatchable production capacity reserve of a certain scale.

By 2030, the production capacity reserve system will be more complete, the production capacity management system will be more complete, and we will strive to form a dispatchable production capacity reserve of about 300 million tons/year. The national coal supply guarantee capacity will be significantly enhanced, and supply elasticity and resilience will continue to improve.

“The establishment of a coal production capacity reserve system is based on the basic national conditions of China’s energy resource endowment and the realistic conditions of coal as the main energy source. It is an important choice to ensure China’s energy security. The establishment of a coal production capacity reserve system can effectively play the role of coal’s ‘ballast stone’ It regulates the balance between energy supply and demand and is the basic guarantee for promoting the smooth operation of the market,” said Xu Liang, director of the Coal Comprehensive Utilization Diversified Management Technology Consulting Center.

Better highlight the support and adjustment function of coal power

The establishment of a coal production capacity reserve mechanism is in line with China’s energy supply laws and is an important measure to ensure energy security. However, some people have also raised questions: At present, China is vigorously promoting the “double carbon” goal. In this context, does the emphasis on coal production capacity reserves meet the development requirements of green and low-carbon energy transformation?

“In fact, building a coal production capacity reserve mechanism is an important part of deepening the energy revolution and accelerating the construction of a new energy system. It is an effective path to implement the carbon peaking action step by step.” Xu Liang said.

From the perspective of power generation utilization, according to data released by the China Energy Administration, the proportion of China’s renewable energy installed capacity in the country’s total installed power generation capacity exceeded 50% last year, historically exceeding thermal power. Renewable energy power generation accounts for about 1/3 of the entire society’s electricity consumption, and wind power and photovoltaic power generation maintain double-digit growth. This illustrates the growing importance of renewable energy in the country’s electricity supply. However, renewable energy sources such as wind and light have the characteristics of “depending on the weather”. When it is extremely hot and windless, and there is no light at night, other energy sources need to be “topped up” in time.

Especially as the proportion of renewable energy installed power generation continues to rise, how to balance “green and low-carbon energy development” and “ensuring stable energy supply” is crucial. Coal power, which used to be the mainstay of coal power generation, can provide support when new energy power generation is unstable, and can turn to play a supporting and regulating role to provide guarantee for energy supply.

“Coal production capacity reserves can effectively increase the flexibility of coal supply, ensure that coal power can better play a supporting and regulating role, promote high-quality development of new energy, and promote green and low-carbon energy transformation.” said an official from the China Energy Administration.

How to build a coal production capacity reserve mechanism?

According to the “Implementation Opinions”, the design production capacity of capacity reserve coal mines consists of conventional production capacity and reserve capacity. Conventional production capacity refers to the normal production capacity of coal mines under non-emergency conditions. Production is organized independently by enterprises according to market conditions and is not included in China’s unified dispatch scope.

Reserve capacity refers to moderate-scale production capacity reserved on the basis of conventional production capacity for peak shaving, which can be released simultaneously with conventional production capacity according to China’s unified dispatch in emergency situations to achieve “upward elastic production” of coal mines. Capacity Reserve The sum of the conventional production capacity and reserve capacity of a coal mine is the design capacity.

Specifically, coal mines that can apply for the construction of reserve capacity should be newly built or under construction coal mine projects approved by the China Development and Reform Commission and the China Energy Administration. The scale of coal mine reserve capacity is divided into 20%, 25%, and 30% according to the proportion of the coal mine’s design capacity. Third gear.

The mining area where the reserve capacity coal mine is located should have convenient external transportation and sufficient transportation capacity. Coal products are mainly used to ensure power generation, heating and energy needs for people’s livelihood.

For coal mine projects that meet the application conditions, the China Energy Administration entrusts relevant evaluation agencies to organize experts to evaluate the coal mine projects that apply for the construction of reserve production capacity. Based on the evaluation results, the list of coal mine projects and the scale of production capacity reserve construction will be determined as a whole, with priority given to supporting Shanxi, western Inner Mongolia, and Mongolia. Large-scale modern open-pit coal mines or underground coal mines with high safety guarantees in the five major coal supply guarantee bases in eastern Shaanxi, northern Shaanxi and Xinjiang.

“After the capacity reserve coal mines are completed, China implements unified dispatching of reserve capacity according to changes in supply and demand in the coal market. When coal supply is tight, the capacity reserve coal mines are organized to ‘upward elastic production’ to quickly release reserve capacity and ensure China’s energy security; when coal supply When supply is sufficient, coal mines with capacity reserves should be organized to produce according to conventional production capacity to reduce fossil energy consumption, make room for the development of new energy, and facilitate the green and low-carbon transformation of energy,” said the above-mentioned person in charge of the China Energy Administration.

Clean, safe and efficient construction of coal production capacity reserves

With the orderly advancement of the “double carbon” goal, clean, safe and efficient coal production has become the consensus of the coal industry to promote green and low-carbon transformation.

At the Heishan open-pit coal mine of Xinjiang Company of China Energy Group, large pieces of earth and stone are continuously transported into the crushing station. After being crushed, they are transported to the dump site as the belt conveyor rotates. As the arm of the dumper rises and falls, these particles are evenly stacked on the dump site – this is the operation scenario of the semi-continuous system for stripping the largest open-pit coal mine in China.

As a modern large-scale open-pit coal mine, Heishan open-pit coal mine has rich resource reserves. The coal has low ash content and high calorific value. It is a high-quality coal favored by the market. However, the rock hardness of the Heishan open-pit coal mine is high, and the traditional stripping process cannot meet the needs of large mines. After using the stripping semi-continuous system, the stripping efficiency can be increased by about 30%, the production capacity can reach 9,000 tons/hour, and coal production is more efficient.

At the same time, the coal mine uses belts to replace fuel vehicle transportation, realizing “replacement of oil with electricity”, significantly reducing fuel consumption, dust and exhaust emissions caused by long-distance transportation of vehicles, achieving the goals of energy saving, consumption reduction, and clean coal production.

Large modern open-pit coal mines and underground coal mines with a high degree of safety are key places for building a coal production capacity reserve mechanism. Cleanliness, safety and efficiency are important principles in the construction process.

The “Implementation Opinions” propose that capacity reserve coal mines mainly form reserve capacity by enhancing mining (stripping) capabilities and increasing the advancement of working faces, and not by increasing working faces. “This shows that the construction of coal production capacity reserves is based on limited resource endowment, safety conditions and environmental protection constraints.

This is mainly achieved by improving existing production capacity and capacity utilization efficiency, which is a manifestation of further leveraging the level of coal mine production technology. The production capacity reserve coal mine coordinates the promotion of energy saving, cost reduction, efficiency improvement and process optimization at the working face, which provides a basic guarantee for reducing environmental pollution from the source. “Xu Liang said.

To guide more enterprises to join the construction of coal production capacity reserves, relevant supporting policies must be supported to encourage enterprises to actively mobilize productivity. The aforementioned person in charge of the China Energy Administration stated that the “Implementation Opinions” proposed relevant supporting preferential support policies in terms of production capacity replacement, overall planning of coal mining areas and planning environmental impact assessment procedures, and new production capacity indicators.

In terms of capacity replacement policy, newly built and under-construction coal mines can be exempted from capacity replacement to varying degrees based on the proportion of reserve capacity construction scale. In terms of overall planning of coal mining areas and planning environmental impact assessment procedures, capacity reserve coal mines are allowed to increase their scale by no more than 30% based on the existing planned scale. In terms of new production capacity indicators, the reserve capacity of capacity reserve coal mines does not occupy the new production capacity indicators in the provinces and regions where they are located.

Coal mine capacity replacement is an important measure proposed by China to promote the structural reform of the coal supply side and promote the transformation and upgrading of the coal industry. China encourages new construction, reconstruction and expansion of coal mines in line with industrial policies to increase production capacity, and realize the replacement of advanced production capacity and backward production capacity in a reasonable manner. Coordinating resource continuity and sustainable development of mining areas. Capacity replacement can promote the development of the coal industry in a high-end, green, and intelligent direction.

These supporting support policies are designed to encourage enterprises to strengthen reserve capacity building, thereby optimizing the layout of coal production and development , accelerating the construction of advanced coal mine production capacity and playing a role in ensuring safe and stable supply of coal.
