Setting the Scene - Coal flexibility in China: context, drivers, and policy evolution

China is repositioning its coal fleet to serve as a regulatory and security resource to manage the variability of its growing renewable energy sector. This transition is driven by a critical need for short-term flexibility, with the IEA estimating that these needs will be three times higher in 2030 than in 2022. To achieve this, the Chinese government has implemented a series of Five-Year Plans and policies, including a target to retrofit "above 200 GW" of coal capacity for flexibility between 2021 and 2025. Technical efforts focus on lowering minimum loads (ML) to 25-40% of rated capacity and decoupling heat and electricity generation in combined heat and power (CHP) units. Financial mechanisms supporting this shift include a coal capacity pricing mechanism introduced in 2024 and the use of infrastructure real estate investment trusts (REITs) for eligible plants.

• China is shifting the strategic role of coal from dominant baseload power to a supporting asset for system flexibility as wind and solar capacity grows. By 2030, renewables are expected to constitute over 50% of total installed power capacity.
• The need for flexibility is intensifying due to the non-dispatchability of renewables and climate-driven extreme weather, which increases summer cooling demand and intraday load fluctuations. The IEA projects that China's short-term flexibility requirements in 2030 will be approximately three times the 2022 levels.
• Coal remains the most practical tool for immediate balancing because China has limited gas capacity due to high costs and import dependency, and coal currently provides about 70% of the country's load regulation capacity.
• The Chinese government has set specific targets for flexibility retrofits across different planning cycles: a goal of 86 GW by 2020 under the 13th FYP, and a target of "above 200 GW" between 2021 and 2025 under the 14th FYP.
• Recent policy updates in February 2024 and 2025 aim to expand these efforts, calling for the entire coal fleet to upgrade "as much as possible" by 2027 and requiring units to operate at a minimum load (ML) of 25-40% depending on the unit type.
• To support the financial viability of plants acting as backup resources, China introduced a coal capacity pricing mechanism in early 2024, which was upgraded in January 2026 to include other resources like pumped hydro and battery storage and to promote market-based pricing.
• Combined heat and power (CHP) units, which make up over 40% of thermal capacity as of 2022, face flexibility constraints due to a "heat-led" operating model. Decoupling heat and electricity via thermal storage or electric boilers is necessary to increase their load regulation capacity, which is often only 10% during heating seasons.
