一 | (ECNS) -- China aims to build more than 100 million metric tons of annual coal production reserve capacity by 2030, according to the 15th Five-Year Plan for Coal Industry Development, jointly released by the National Development and Reform Commission (NDRC) and the National Energy Administration (NEA) on Monday. By 2030, China's capacity to ensure secure coal production and supply is expected to be further strengthened, while the structure and distribution of coal production will continue to improve. Large modern coal mines are expected to account for 87% of the country's total production capacity, according to the plan. The plan also aims to significantly improve coal mine safety, green development, and the clean and efficient use of coal. Smart mines are expected to account for 75% of total production capacity, while the development of a more diversified coal-based industrial structure will be accelerated. Coal consumption is expected to peak during the plan period, alongside the establishment of a more robust mechanism for balancing supply and demand. The plan places energy security alongside the green transition as key priorities. Focusing on the development of a modern coal industry system, it outlines nine major tasks, including optimizing coal development and spatial distribution, accelerating industrial restructuring, and strengthening the production, supply, storage and sales system. Other priorities include advancing the green and low-carbon transition, improving the clean and efficient use of coal, and promoting technological innovation. The plan also calls for stronger safety management, modernized industry governance, and a higher level of modernization across the sector.
