Coal Energy infrastructure in India

Published on 25 Feb 2025

Coal energy infrastructure in India is a critical component of the country's energy sector, given that coal remains the primary source of electricity generation. 

•  Coal Reserves and Production:

• India has the fifth-largest coal reserves globally, with over 344 billion tonnes.

• The country is the second-largest coal producer, with Coal India Limited (CIL) accounting for 80% of annual production.

• Thermal Power Plants and Generation:

• Coal-fired power plants generate about 70% of India's electricity.

• India has over 200 coal-based thermal power plants, mainly in Maharashtra, Uttar Pradesh, and Tamil Nadu.

• Transportation and Logistics:

• Nearly 60% of coal for power generation is transported by railways, but logistical constraints affect efficiency.

• Limited rail connectivity between mines and plants remains a significant challenge.

• Coal Imports and Dependency:

• India imports around 200 million tonnes of coal annually, especially coking coal for steel production.

• Major coal imports come from Indonesia, Australia, and South Africa.

•  Environmental Impact and Modernization:

• Coal-based energy infrastructure is a leading source of CO2 emissions in India.

• The government is focusing on modernizing plants with supercritical and ultra-supercritical technologies to enhance efficiency and reduce emissions.

•  Shift Towards Renewable Energy:

• While coal dominates, India is increasingly investing in renewable energy to reduce coal's share in electricity generation.

• This transition aligns with the country's commitment to the Paris Agreement and reducing environmental impact.

Coal Energy Crises in India

• Aging Coal-Fired Power Plants: Over 50% of India’s coal-fired power plants are over 25 years old, leading to reduced efficiency and higher operational costs.

• Example: The Dadri Power Plant in Uttar Pradesh, built in the 1990s, frequently operates at a reduced capacity due to outdated technology.

• Inadequate Mining Infrastructure: India’s coal mines, particularly in Jharkhand and Odisha, lack modern equipment, with mechanization rates below 50%.

• Example: The Rajmahal coal mine in Jharkhand struggles with frequent breakdowns of its aging draglines, reducing its output during peak demand.

• Transportation Bottlenecks: Nearly 60% of coal is transported via rail, but inadequate rail infrastructure causes delays.

• Limited Storage and Handling Facilities: India’s coal storage infrastructure can only hold reserves for 15-20 days, far below the required 30 days for stable supply.

• Example: The NTPC Dadri plant has faced operational shutdowns due to a lack of coal storage capacity, particularly during peak summer months.

• Dependence on Key Transport Corridors: Critical rail corridors like the Howrah-Delhi route handle 40% of coal traffic, leading to congestion and delays.

• Example: Coal shipments to the NTPC Singrauli plant are often delayed due to over-reliance on this route, affecting power generation during peak demand periods.

• Delayed Infrastructure Projects: Over 20 major coal infrastructure projects, including new mines and rail links, are delayed by 2-3 years due to regulatory approvals.

• Example: The Talcher coalfield expansion project in Odisha has faced delays due to environmental clearances, impacting coal supply to nearby power plants.

• Lack of Modernization in Mining Techniques: Only 10-15% of India’s coal mines use advanced technologies like continuous miners or longwall mining, limiting productivity.

• Example: The Singareni Collieries Company Limited (SCCL) has been slow to adopt modern mining methods, resulting in lower-than-expected coal output.
