India’s Coal Backbone Holds Firm Amid Global Gas Disruptions

India’s energy ecosystem is witnessing early signs of stress amid ongoing geopolitical disruptions in West Asia, even as the government maintains that the country remains well-prepared to manage the situation. The ongoing conflict in the region has significantly impacted global supply chains, particularly energy flows through critical routes such as the Strait of Hormuz, which carries a large share of India’s crude oil, gas, and fertiliser imports. Addressing the Parliament on March 23, Hon’ble Prime Minister Shri Narendra Modi described the situation as “concerning” and acknowledged its adverse impact on the global economy and daily life, while assuring that India is taking proactive steps to safeguard energy security.

Industrial clusters across India are already experiencing localized stress, with shortages and disruptions in CNG and LPG supply pushing businesses to explore alternative fuels, including coal. India imports nearly 45–50% of its natural gas requirement as LNG, making industrial gas consumers highly sensitive to global supply disruptions and shipping route uncertainties. This shift is further reinforced by constrained LNG supplies and rising global uncertainties. At the same time, the government has highlighted that India has significantly strengthened its energy resilience over the past decade through diversification of import sources, expansion of strategic reserves, and improved supply chain preparedness.

Gas-based power capacity in India remains underutilised at below 25% PLF, as coal and renewables continue to dominate the generation mix. While the power sector remains relatively insulated, owing to its strong reliance on coal and renewables, the industrial sector continues to feel the pressure of gas shortages. In this context, coal has emerged as a critical fallback option, reinforcing its role as the backbone of India’s energy security.

India’s overall coal demand has been rising steadily, with annual consumption crossing 1.25 billion tonnes, driven primarily by the power sector, cement, sponge iron, and captive industrial users. Early signals from coal markets indicate tightening demand–supply dynamics. Coal India’s e-auction premiums have risen to around 35% over notified prices in February 2026, reflecting increased urgency among buyers to secure supply. This marks a shift from softer demand trends earlier in the fiscal year. The demand uptick is being driven by multiple factors, including substitution from gas amid LNG disruptions, seasonal ramp-up in power demand, and reduced imports leading to greater reliance on domestic coal. However, coal’s substitution potential remains largely limited to the power sector in the short-to-medium term. Structural and technological constraints continue to restrict its widespread adoption in industrial applications such as fertilisers and chemicals.

Commenting on the evolving scenario, Mr. Vinaya Varma, MD & CEO, mjunction services limited stated, “What we are witnessing is an early but clear behavioural shift in fuel consumption patterns. As LNG availability tightens and CNG/LPG supplies face disruption in several industrial clusters, buyers are increasingly turning to coal to secure operational continuity. The rise in e-auction premiums and improved offtake reflects this urgency. Coal will continue to play a critical role in ensuring India’s energy security, especially in times of global uncertainty. While we are witnessing localized tightening in demand and firming of prices, the overall market remains balanced due to strong domestic availability and adequate stock levels.”

Importantly, the situation remains measured rather than overheated. Only about 47% of auction volumes have been sold so far this year, and current premiums remain below historical peaks, indicating controlled but firming demand. Current coal stock levels at power plants remain comfortable at 18–20 days of consumption, preventing panic buying despite tightening spot demand signals in auction markets. Overall, while India is not facing an immediate energy crisis, evolving global disruptions are beginning to test the system.

SAIL's Bhilai Plant Pioneers Next-Gen Steel for S5 Nuclear Ballistic Missile Submarines (SSBNs)

The Steel Authority of India Limited's (SAIL) Bhilai Steel Plant (BSP) has made a significant advancement in the development of strategic defense materials. They have pioneered the creation of next-generation steel designed specifically for the S5 class of nuclear-powered ballistic missile submarines (SSBNs).

The S5-class submarine is a planned class of Indian nuclear-powered ballistic missile submarines (SSBNs) currently under development for the Indian Navy.

This new steel is currently undergoing a comprehensive multi-year testing phase to ensure it meets the stringent performance requirements necessary for underwater applications.

Once the testing phase is successfully completed and the steel is cleared for use, it will be utilized in the construction of the S5 class SSBNs. These submarines are reported to be true underwater giants with an estimated submerged displacement exceeding 12,000 tons and a length of nearly 150 meters.

The S5 class submarines are expected to significantly enhance India's underwater deterrence capabilities and reinforce its position as a leading maritime power.

The S5 class submarines project was assessed by the Government of India in 2006, and production is expected to start by 2027. These submarines are part of India's strategic nuclear deterrent and are expected to play a crucial role in the country's defense strategy by providing a second-strike capability. The S5- class will contribute to the triad of India's nuclear deterrence, which comprises land- based missiles, strategic bombers, and SSBNs.

The next-generation steel developed is designed to meet the specific demands of modern submarine construction. While official details on the composition and properties of this new steel are classified, it is undergoing rigorous testing to ensure it surpasses the performance requirements for underwater applications.

Compared to existing materials, this new steel variant is likely to offer improved strength, corrosion resistance, and longevity, which are critical for the harsh conditions submarines encounter in deep-sea environments. The development process for this steel is more extensive than that for the steel used in the INS Vikrant aircraft carrier, indicating a significant advancement in quality and performance.

This specialized steel is expected to enhance the structural integrity and safety of the S5 class submarines, contributing to India's strategic defense capabilities and supporting the nation's goal of self-reliance in defense technology.

This initiative is part of India's strategic move towards self-reliance in defense capabilities. The steel produced by BSP will undergo extensive testing and inspection by the Defence Metallurgical Research Laboratory (DMRL) and the Indian Navy before it is used in the construction of the Submarine.

The development of this steel is a testament to SAIL-Bhilai's commitment to contributing to major defense projects, following their previous work on special steel plates for the INS Vikrant aircraft carrier. The testing for the submarine steel is reported to be ten times more rigorous than that for the steel used in INS Vikrant, highlighting the critical nature and high standards required for submarine construction.

This project is a significant step in bolstering India's defense infrastructure and enhancing its maritime security. The indigenous development of submarines using materials produced within the country not only strengthens national security but also supports the growth of domestic Industries.
