Coal Power Declines in China and India in Rare Simultaneous Shift

Coal-fired electricity generation declined in both China and India in 2025, marking an uncommon and potentially far-reaching shift in the energy pathways of the world’s two largest coal-consuming nations. It is the first time in several decades that coal output has fallen in both countries in the same year, a development that has drawn close attention from energy analysts, investors and climate policymakers alike.

China and India together account for more than half of global coal-based electricity generation. For much of the past two decades, rising power demand in these economies has underpinned global coal consumption, even as usage declined steadily across Europe and parts of North America. As a result, any sustained change in coal use in Asia's two largest economies carries profound implications for global fuel markets, emissions trajectories and long-term energy investment.

Analysts say the decline in coal-fired electricity generation in 2025 was driven largely by the continued expansion of renewable energy, with solar and wind power increasingly meeting demand that would previously have been supplied by coal. Data from energy agencies and grid operators show that both China and India added renewable capacity at a scale that allowed clean energy to play a more prominent role in power generation, particularly during daylight hours and periods of strong wind.

China further strengthened its position as the world’s largest renewable energy market, commissioning large utility-scale solar projects while accelerating the rollout of onshore and offshore wind capacity. Ongoing investment in transmission infrastructure supported these additions, enabling more efficient delivery of renewable electricity to major demand centres.

India also expanded its renewable footprint, bringing new solar parks and wind projects online as part of its broader strategy to diversify the power mix and reduce reliance on imported fuels. Improvements in grid connectivity and dispatch systems allowed renewable generation to supply a growing share of daytime electricity demand, particularly in regions with high solar output.

Coal-fired power plants saw a decrease in intensity as renewable generation surged. In several regions, coal units operated for fewer hours and at lower utilisation rates, reflecting their growing role as backups or balancing capacities rather than primary sources of electricity. Energy specialists say this shift points to a gradual change in how coal is used within power systems, even as it remains important for reliability during periods of low renewable output.

The trend, analysts add, underscores the impact of policy support for renewables, falling technology costs and grid upgrades in reshaping electricity markets in the world’s largest energy-consuming economies.

Energy specialists say this represents a structural shift, with renewables now shaping system-wide power generation rather than merely supplementing fossil fuels at the margin.

Weather conditions also played an important supporting role. Energy analysts say weather patterns and demand trends also played a role in reducing coal-fired electricity generation during the year. Periods of milder-than-average temperatures lowered demand for both heating and cooling, easing pressure on power systems and reducing the need for coal-based generation during peak periods.

At the same time, overall growth in electricity demand slowed compared with previous years, particularly in energy-intensive industries affected by broader economic conditions. Analysts note that softer industrial output reduced baseline power consumption, further limiting the call on coal-fired plants.

While these factors are cyclical rather than structural, energy specialists say they reinforced the impact of expanding renewable energy capacity, helping to suppress coal generation over the year. Policymakers and market observers caution that weather-related effects can reverse but argue that demand moderation combined with cleaner energy growth highlights the increasing complexity of managing power systems during the energy transition.

Despite the drop in coal-fired generation, experts caution against interpreting the figures as evidence of a rapid retreat from coal. In both China and India, coal remains deeply embedded in energy security strategies. Energy policymakers in both China and India continue to place a strong emphasis on maintaining reliable and affordable electricity supplies, even as renewable energy accounts for a growing share of generation. Officials and energy planners say one of the central challenges is managing the technical complexity of integrating large volumes of variable solar and wind power into national grids while avoiding supply disruptions.

In China, authorities have continued to approve and bring new coal-fired power plants online, arguing that additional capacity is needed to support grid stability as renewable penetration rises. Chinese energy officials have said coal plants are increasingly intended to provide system flexibility and backup during periods when renewable output is low, rather than to drive long-term growth in coal generation.

Analysts observe that this strategy mirrors a wider policy balance between energy security and decarbonisation objectives, where coal assumes a transitional role as grid infrastructure, storage capacity, and power market reforms continue to progress.

Policymakers in Beijing have repeatedly described coal as a supporting or balancing fuel rather than a growth driver, with new plants designed to operate flexibly—ramping up when renewable output falls and scaling back when clean energy is abundant.

India has taken a broadly comparable approach to managing the transition in its power sector. Although renewable energy capacity is expanding at a rapid pace, coal continues to play a central role in electricity generation, reflecting policy priorities around affordability, system reliability and economic growth.

Energy analysts assert that peak demand requirements and grid-balancing needs, rather than continuous baseload generation, increasingly influence coal use in India. As solar and wind output fluctuate throughout the day, coal-fired plants are being used more flexibly to maintain stability during periods of high demand or low renewable availability. 

Policymakers and power system operators argue that this approach allows India to scale up clean energy while safeguarding energy security, particularly as the country continues to expand industrial activity and electricity access.

What appears to be changing, therefore, is coal’s function rather than its presence. Energy specialists say coal is increasingly shifting away from its long-standing role as a constant source of baseload electricity to a more limited function focused on system support and grid stability. As more renewable energy sources come online, coal-fired plants are being used less often. Instead of running all the time, they only run when solar and wind power aren't enough.

Analysts note that this change has important implications for the economics of coal power. Reduced operating hours can erode revenues, affecting plant profitability, fuel procurement patterns and long-term investment plans. As the cost of renewable energy continues to decline, older or less efficient coal plants face growing financial pressure, particularly in markets where clean energy is increasingly competitive.

The simultaneous fall in coal-fired electricity generation in both China and India has therefore drawn close attention from global energy markets. Investors and fuel suppliers are assessing whether the trend reflects a temporary adjustment or the early stages of a broader shift in how coal is used within the world’s largest power system.

We have long viewed Asia as the centre of future coal demand growth, and any sustained slowdown would reshape global coal trade flows. Major exporters such as Australia, Indonesia and South Africa are watching developments closely, as are investors assessing long-term demand risks in fossil fuel markets.

Climate analysts say the trend could have meaningful implications for global emissions. Coal remains the single largest source of energy-related carbon dioxide emissions worldwide. A sustained reduction in coal use in Asia’s largest economies would significantly alter projections for future emissions growth, even if absolute coal consumption remains high in the near term.

However, experts also warn that a single year of decline does not establish a long-term pattern. Coal generation remains sensitive to weather variability, economic cycles and policy decisions. A return to stronger electricity demand growth, prolonged heatwaves or periods of weak renewable output could still trigger a rebound in coal use, particularly if investment in energy storage and grid infrastructure fails to keep pace with renewable expansion.

The coming years are therefore likely to be decisive. Continued investment in grid modernisation, energy storage technologies, and flexible power systems will determine whether renewables can permanently limit coal's role. Policy consistency will also be critical, as governments balance decarbonisation goals with energy security and economic growth.

For now, the 2025 decline stands as a clear signal that coal’s long-assumed growth trajectory in Asia is no longer guaranteed. Renewable energy is beginning to exert tangible influence even in the most coal-dependent power systems. While coal is unlikely to disappear in the near future, its dominance is increasingly being challenged.

This shift is a significant milestone in the global energy transition.
