India’s coal industry stands at a critical juncture as stockpiles at pitheads and power plants continue to surge, placing pressure on state-owned mining corporations, such as Coal India Limited (CIL). This build-up stems from a confluence of high production, softer-than-expected demand, and logistical constraints, exposing structural challenges in India’s energy supply chain.
While India’s commitment to coal as its primary energy source remains firm, the growing mismatch between supply and consumption is sparking concerns about inefficiency, wasted resources, and the financial viability of public-sector mining operations. With the monsoon season approaching and power consumption patterns changing, the coal stockpile dilemma is now a significant test for policy planners and energy administrators.
Rising Coal Production Outpaces Demand
India has seen a significant uptick in coal production, particularly in the first half of 2025, with Coal India Limited surpassing previous output records. This production boom is partly a result of government pressure to ensure uninterrupted coal supply following the severe shortages in 2021 and 2022. However, current electricity demand, although steady, has not kept pace with these production levels.
Power utilities have improved their efficiency and diversified their fuel mix, with renewables accounting for a larger share than in previous years. Consequently, a sizable portion of mined coal remains unused, resulting in swollen stockpiles at both pitheads and power plants.
Challenges Faced by Coal India Limited
Coal India Limited, the country’s largest coal producer and a key state-owned enterprise, is facing mounting operational and logistical challenges. With more than 80 million tonnes of coal in stock as of June 2025, CIL is grappling with storage constraints and increased handling costs.
The situation is made more difficult by the slow movement of offtake from power plants and industrial users. Many coal buyers are deferring deliveries or slowing down their procurement pace, citing full inventories and reduced consumption. These factors are not only straining CIL’s supply chain but also putting pressure on its financial metrics, particularly working capital and profitability ratios.
Logistical Bottlenecks Amplify Storage Problems
One of the most pressing issues contributing to the growing coal inventory is India’s creaky logistics infrastructure. While coal mines are operating at high capacity, evacuation to power plants and industries is being hindered by limited rail connectivity, insufficient rakes, and poor road conditions at the last mile.

Indian Railways, although ramping up wagon availability, continues to face bottlenecks in coal-rich regions such as Jharkhand, Chhattisgarh, and Odisha. The delayed transit from pitheads to consumption centers means mined coal often sits idle, adding to inventory burdens and increasing the risk of quality degradation.
Power Plants Hesitant Amid Changing Consumption Trends
Thermal power plants are now operating under a more flexible and diversified power generation strategy. Many states have increased their solar and wind generation capacities, thereby reducing reliance on coal during off-peak periods.
This shift has led to a more cautious approach to coal procurement by power distribution companies (discoms). Instead of overstocking coal, they are aligning purchases closely with short-term demand forecasts. This conservative buying approach is contributing to the low offtake despite the abundance of supply from Coal India and other producers.
Financial Impact on State-Owned Coal Enterprises
For state-run miners like Coal India, bloated inventories translate to increased operational costs and cash flow issues. Unsold coal ties up capital in non-productive assets, leading to liquidity stress and affecting dividend payouts to the government, which remains the majority shareholder.
In the fiscal year 2024–25, Coal India reported a significant increase in its unsold stock, resulting in a decline in quarterly revenues despite higher production figures. This anomaly points to a deeper disconnect between production planning and market absorption. If left unaddressed, the financial health of public-sector mining companies could come under serious threat.
Government Response and Strategic Adjustments
The Indian government is now actively reviewing coal dispatch strategies to tackle the growing stockpile crisis. The Ministry of Coal, in coordination with Indian Railways and state governments, is developing real-time tracking systems and prioritizing corridor development for coal transport.
Additionally, there are discussions about redirecting surplus coal for export or to non-power sectors, such as cement and steel, although these markets are limited in scope. Strategic coal reserves are also being considered to absorb excess stock while supporting long-term energy security objectives.
Environmental and Policy Implications
The accumulation of coal stockpiles is not only an economic concern but also an environmental one. Open stockyards contribute to air pollution, especially during dry seasons when coal dust becomes airborne. Moreover, prolonged exposure to the elements degrades coal quality, reducing its calorific value and increasing ash content thereby impacting combustion efficiency at power plants.
This situation highlights the need for more effective inventory management and integration with clean energy policies. It also raises important questions about India’s long-term coal dependency in light of its climate commitments under international frameworks, such as the Paris Agreement.
Industry Stakeholders Call for Market Reforms
Industry bodies and energy think tanks are advocating for reforms in coal trading and pricing mechanisms. The current system, largely dominated by long-term contracts and government allocation, lacks the flexibility needed to respond to rapid changes in demand and supply.
Experts recommend expanding the role of coal spot markets and enhancing private sector participation to ensure more dynamic pricing and efficient distribution of coal. Such reforms could enable Coal India and other state-run firms to adapt more effectively to consumption trends and mitigate the risk of stockpile surpluses.
Role of Renewable Energy in Shifting Demand Dynamics
India’s ambitious renewable energy targets are beginning to reshape energy consumption patterns across states. Solar and wind installations have grown steadily, with several states now sourcing 30–40% of their energy needs from clean sources during peak production hours.
This renewable push, while vital for sustainability, complicates the forecasting of coal demand. Energy planners must now strike a delicate balance between ensuring enough coal for baseload power and avoiding overproduction that leads to waste and financial inefficiency.
Frequently Asked Questions
Why are coal stockpiles increasing in India?
Coal stockpiles are increasing due to higher-than-needed production by state-owned firms, combined with sluggish offtake by power plants and industries.
What challenges does Coal India face due to the surge in stockpiles?
Coal India faces logistical issues, rising storage costs, declining coal quality, and financial strain due to unsold inventory.
How is the Indian government addressing the coal surplus?
The government is working on improved logistics, exploring export opportunities, and considering reserves to manage excess stock.
Are renewable energy sources affecting coal demand?
Yes, the growing share of solar and wind energy is reducing the need for coal-based power, especially during certain hours of the day.
What is the role of Indian Railways in coal logistics?
Indian Railways plays a crucial role in transporting coal, but it is currently facing capacity bottlenecks that hinder the timely movement of coal.
Can India export its surplus coal?
India has limited coal export markets due to the domestic-grade characteristics of its coal and global competition from countries such as Australia and Indonesia.
How does coal degradation affect power generation?
Degraded coal loses energy content, increases ash output, and reduces combustion efficiency, leading to higher operational costs for power plants.
What reforms are being proposed to prevent future stockpiles?
Proposed reforms include expanding coal spot markets, integrating digital inventory systems, and improving demand forecasting tools.
Conclusion
India’s swelling coal stockpiles are testing the resilience and agility of its state-run mining behemoths. As the country navigates a complex energy transition, balancing coal security with environmental responsibility and logistical efficiency remains crucial. Without swift policy and operational reforms, surplus stockpiles could morph from an operational hiccup into a prolonged structural bottleneck.
