전 세계 석탄발전소 추이 조사
In 2025, global coal power capacity increased by 3.5% while generation fell by 0.6%, reflecting a trend where coal plants act as 'system insurance' rather than primary power sources. This gap is most prominent in China and India, where record-high completions coexist with falling generation due to rapid wind and solar expansion. While the number of countries proposing new coal projects decreased from 38 in 2024 to 32 in 2025, and Latin America reached a state of no new proposals, some regions like the US and EU delayed planned closures due to energy security and political intervention. South Korea has committed to a 2040 coal phase-out, contrasting with Japan's more gradual approach focused on ammonia co-firing and efficiency improvements.

2025 in Review
In 2025, global electricity generation reached a historic milestone as renewables overtook coal power for the first time in 100 years, accounting for 33.8% of the global mix. This shift was driven by a record increase in solar power generation (636 TWh), which alone met 75% of the global electricity demand growth. Consequently, global fossil generation saw a slight decline of 38 TWh, marking the first such decrease since 2020 outside of a global recession or exceptionally mild year. This trend was most prominent in China and India, where fossil generation fell for the first time simultaneously in the 21st century. While Asia remains the only region where coal still exceeds renewables, the global emissions intensity of electricity fell to 458 gCO2e per kilowatt hour in 2025.

Conflict in the Middle East is compounding the cost of Bangladesh delayed energy transition
Conflict in the Middle East is disrupting critical energy imports to Bangladesh, particularly through the Strait of Hormuz, leading to fuel rationing, power cuts, and industrial shutdowns. ZCA analysis indicates that sustained high prices for oil, gas, and coal could increase Bangladesh's annual fossil fuel import bill by USD 4.8 billion (a 40% increase from 2025 levels), further straining foreign exchange reserves. The document argues that this recurring volatility, echoing the shocks from the Russia-Ukraine war, underscores the urgent need for Bangladesh to pivot toward renewable energy to avoid long-term fiscal distress and energy insecurity.

From baseload to flexibility: How is coal’s role in China changing
China is repositioning its coal fleet to provide system flexibility, with the entire existing fleet on track to be retrofitted by 2027. While technical capacity is increasing, the report argues that full flexibility is constrained by power market design and dispatch practices. It emphasizes that as coal retrofit potential plateaus, the rapid scale-up of clean flexibility, particularly battery energy storage, is essential to avoid locking in emissions beyond 2030 and to maintain grid stability as renewables become dominant.

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.

Measuring the Impact - China’s coal fleet is becoming more flexible, but much of its potential remains untapped
China has rapidly expanded its flexible coal power capacity, exceeding its 2025 national target and positioning itself to meet a 2027 goal of retrofitting 500-700 GW. By the end of 2024, total flexible coal capacity exceeded 600 GW, with significant progress in provinces like Guangxi, Inner Mongolia, Shanxi, and Xinjiang. While coal utilisation is generally declining and showing greater seasonal variability due to renewable growth and demand peaks, the document notes that the full potential of this technical flexibility is not yet reflected in system operations due to market design and institutional arrangements. The transition is supported by a capacity pricing mechanism and diversified revenue models, though flexible operation increases costs through higher maintenance, reduced fuel efficiency at low loads, and accelerated depreciation.

재생에너지로 한국의 국가 안보 보장
The report argues that South Korea's heavy reliance on imported fossil fuels (84% of total energy supply) creates critical vulnerabilities to geopolitical conflicts in the Strait of Hormuz, Malacca Strait, and South China Sea, as well as climate-driven infrastructure risks. It posits that a rapid shift to renewables can mitigate these risks, reduce financial burdens associated with energy price volatility, and support the energy needs of advanced AI and defense systems. While acknowledging challenges such as China's dominance in critical mineral supply chains and cybersecurity risks associated with digitalized grids, the document concludes these are manageable through battery storage innovation, grid modernization, and supply chain diversification. It recommends integrating renewable energy goals explicitly into national security planning and the 12th Basic Plan for Electricity Supply and Demand.

Built to peak: Coal power expansion runs out of room in China
China experienced a record surge in coal power commissioning and project proposals in 2025, despite a decline in actual coal power generation and the rapid growth of clean energy and storage. The report highlights a growing gap between investment decisions and system realities, noting that new capacity is dominated by large, inflexible units designed for baseload operation. This trend risks creating stranded assets and structural barriers to decarbonisation. The authors argue that the 15th Five-Year Plan must end net coal capacity growth and shift coal's role from a primary energy source to a flexible, residual support system to meet 2030 climate targets.
