There is no requirement. According to the "Inquirer" news, resolving the backward production capacity of the coal industry is an important part of the supply-side structural reform. According to the requirements of the national coal de-capacity work, the new coal production capacity must follow the principle of increase and decrease, and the new coal production capacity must be completely reduced and replaced. The quantity here is not heat, but output, and there is no requirement for heat. Coal mine projects under construction should be linked to eliminating backward production capacity and resolving excess production capacity according to a certain proportion, so the coal production capacity replacement index has no requirement for heat.
