Coal Power Survives—But Must Change
💡AI compute growth depends on power policy—this explains how China may balance coal and flexibility.
⚡ 30-Second TL;DR
What Changed
Coal-fired power is expected to remain part of the future electricity mix
Why It Matters
For AI companies, electricity availability and grid flexibility are becoming strategic constraints on data-center expansion. A more flexible power system could support large AI workloads, but regional carbon, transmission, and capacity limits will still affect infrastructure planning.
What To Do Next
Add regional grid capacity, carbon intensity, and renewable-availability variables to your AI data-center site-selection and workload-scheduling models.
Key Points
- •Coal-fired power is expected to remain part of the future electricity mix
- •Coal plants may need to shift from baseload generation toward flexible balancing
- •The plan reflects broader changes in grid structure, power-market coordination, and energy-system integration

🔑 Enhanced Key Takeaways
- •Academician Liu Jizhen emphasizes the 'dual-track' strategy where coal power transitions from providing primary energy to providing primary capacity and flexibility services.
- •The 15th Five-Year Plan framework prioritizes the integration of 'source-grid-load-storage' to mitigate the intermittency of high-penetration renewable energy sources.
- •China is accelerating the technical retrofitting of existing coal units to achieve deep-peak shaving capabilities, often targeting minimum loads of 20-30% of rated capacity.
- •The policy shift necessitates a transition in power market mechanisms from energy-only markets to capacity-based compensation models to ensure the economic viability of flexible coal assets.
- •Liu Jizhen advocates for the large-scale deployment of 'coal-fired power + carbon capture, utilization, and storage (CCUS)' as a critical pathway to reconcile coal usage with national carbon neutrality targets.
🛠️ Technical Deep Dive
- Deep Peak Shaving: Implementation of boiler combustion optimization and steam turbine bypass systems to allow coal units to operate stably at 20% load.
- Flexibility Retrofitting: Integration of thermal energy storage systems within coal plants to decouple power generation from heat supply, enhancing response times to grid frequency fluctuations.
- Digital Twin Integration: Deployment of AI-driven predictive maintenance and real-time control systems to manage the increased thermal stress caused by frequent load cycling.
- CCUS Implementation: Utilization of post-combustion chemical absorption (amine-based) technologies to capture CO2 emissions from flue gas, requiring significant auxiliary power consumption.
