On August 3, the National Development and Reform Commission, in collaboration with the National Energy Administration, unveiled the "15th Five-Year Plan" for Constructing a New-Type Power System. This plan explicitly promotes the conversion of coal-fired power into supportive and regulating energy sources. It adheres to the mandates outlined in the special initiative for upgrading next-generation coal-fired power, bolstering the ability of coal-fired power to perform deep, rapid, and efficient regulation. Additionally, it refines the capacity price mechanism for coal-fired power. According to the plan, by 2030, flexibility upgrades for all existing units should be fully accomplished. Specifically, the minimum power output of combined heat and power (CHP) units must be lowered to below 40%. The plan also advocates for further enhancing flexibility through collaborative approaches, such as electro-thermal decoupling, to guarantee a stable heat supply.
