Abandoned coal mines develop PV trend

Recently, the State Council issued the “Opinions on the Coal Industry Resolving Excessive Production Capacity to Realize the Development of Poverty” Guofa No. 7 Document [2016]. The basic principle of the "Opinions" is that the market is forced to combine with government support, and the combination of capacity reduction and transformation and upgrading will be combined with overall promotion and key breakthroughs. From the beginning of 2016, with a period of 3 to 5 years, it will withdraw from the production capacity of 500 million tons, and reduce the restructuring by 500 million tons. This will significantly reduce the coal production capacity, moderately reduce the number of coal mines, and effectively eliminate excess production capacity in the coal industry. The basic balance between supply and demand, the optimization of the industrial structure, and substantial progress in transformation and upgrading.

The "Opinions" proposed that the industry should be adjusted and transformed, and the use of abandoned coal mine industry squares and their surrounding areas should be encouraged to develop wind power, photovoltaic power generation and modern agriculture. We will revitalize the land resources, support the withdrawal of coal mines from the use of well-stocked land, and promote a number of measures such as upgrading and reconstruction of mining areas and the redevelopment of land.

It is understood that many domestic coal companies have already entered the photovoltaic industry, such as Inner Mongolia Shenhua Group, Yitai Group, Inner Mongolia Erdos Group, Shanxi Jinneng Group, etc. Among them, Shanxi Jinneng Group, in addition to investing in PV power plant, also involved in the R&D and manufacturing of photovoltaic cells and modules. Jinneng Clean Energy has announced that the average efficiency of mass-produced polycrystalline cells has successfully exceeded 18.7%, and the mass production of polycrystalline modules has been achieved. Significantly improved, 270 watts module output ratio reached 60%. Up to now, Jinneng Technology has implemented three generations of industry-leading technology layouts: high-efficiency polycrystalline, PERC, and heterojunction.

On June 19 last year, the National Energy Administration approved the construction of the National Advanced Technology Photovoltaic Demonstration Base in Datong Coal Mining Subsidence Area. In the future, the implementation of the special photovoltaic support plan will be implemented through the construction of advanced technology photovoltaic power generation demonstration bases and new technology application demonstration projects. . At the same time, in the future, government financial support and procurement will also give priority to the use of technologies developed by leading companies and products produced.

According to China's "13th Five-Year Plan" photovoltaic planning comments, PV will be built in the "Thirteenth Five-Year Plan" period, a typical demonstration base of 12.4 GW. It will focus on the construction of photovoltaic power generation comprehensive treatment projects in Shanxi Datong, Yangquan, Shanxi, Jining, Shandong, and coal mining subsidence areas in Baotou, Inner Mongolia, and actively promote the development and construction of photovoltaic power generation comprehensive treatment projects in goafs and reserve mining areas such as Anhui, Huaihe, Liaoning, Shanxi, and Inner Mongolia. The total planned size is 15.4 GW and the built-up capacity exceeds 10 GW in 2020.

As one of China’s important coal resource bases, due to long-term mineral extraction in Baotou, Inner Mongolia, the surface soil of the ore body in the subsidence area was stripped and the surface vegetation was severely damaged. Soil erosion and soil desertification were severely aggravated, and surface deformation and collapse were evident, resulting in a large number of The abandoned land. According to the "Plant Project of Photovoltaic Industry Demonstration Base for Coal Mining Subsidence Area in Baotou City," which was publicized recently, the total capacity of long-term PV planning in Baotou City, Inner Mongolia, is 2 GW, which is 1 GW in this period. The development of the photovoltaic base area will be used to solve the problem. The problem of idle land in coal subsidence areas will help coal mining subsidence areas achieve energy transformation. The construction targets of photovoltaic bases have met the standards of the “leadership” plan, promoted the advancement of photovoltaic technology and industrial upgrading, and finally built a photovoltaic base with advanced technology demonstration significance. The construction of photovoltaic base and photovoltaic industry has effectively helped the coal mining subsidence area and the surrounding villagers increase their income and drive the local economic development.

It is reported that coal mining subsidence area management, photovoltaic industry, poverty alleviation, photovoltaic industry, technological progress, industrial upgrading and innovative photovoltaic scale index management organically combine to solve the problem of idle land in subsidence areas, and overall promote the industrial development of subsidence areas, farmers income and ecological environment Governance is of great significance in promoting the transformation of energy-based cities into energy development.
