What Happened
- As the West Asia conflict exposed India's acute vulnerability in LPG supply, the three state-owned Oil Marketing Companies (OMCs) — Indian Oil Corporation (IOC), Bharat Petroleum (BPCL), and Hindustan Petroleum (HPCL) — began pushing for expanded LPG storage facilities to reduce future risk.
- India's current strategic LPG storage capacity stands at approximately 140,000 tonnes, barely five days of national demand — critically insufficient to buffer against prolonged supply disruptions.
- India has two operational underground LPG caverns: 80,000 MT at Mangalore (HPCL, commissioned late 2025) and 60,000 MT at Visakhapatnam; combined, these provide only a fraction of monthly import volumes.
- The West Asia conflict led to approximately 320,000 tonnes of LPG being stranded on 22 vessels at peak disruption, exceeding total strategic LPG storage capacity — underscoring the infrastructure gap.
- OMCs are also operating under a government directive (March 8, 2026) to maximise domestic LPG production by diverting propane, butane, propylene, and butenes streams, boosting domestic output by approximately 25%.

India's LPG Supply Chain — OMCs, Imports, and Distribution Infrastructure
India's LPG supply chain is controlled by three public sector OMCs: IOC (Indian Oil Corporation), BPCL (Bharat Petroleum Corporation Ltd), and HPCL (Hindustan Petroleum Corporation Ltd). Collectively, they distribute LPG through 25,481 distributors to over 32.94 crore active domestic connections. Approximately 60% of India's LPG demand is met through imports, with over 90% of those imports routed through the Strait of Hormuz. Domestic LPG production — sourced from oil refineries and gas processing units — stands at around 1.16 million tonnes/month, while imports are nearly double that at ~2.19 MT/month. The Pradhan Mantri Ujjwala Yojana (PMUY) has expanded LPG access to 10 crore BPL households since 2016, sharply increasing the number of households dependent on this single fuel.
- IOC, BPCL, HPCL are Navratna/Maharatna public sector enterprises under the Ministry of Petroleum and Natural Gas.
- Active LPG connections: 32.94 crore through 25,481 distributors.
- PMUY: launched May 2016; target of 10 crore connections for BPL households by 2023 (achieved).
- Domestic LPG production: ~1.16 MT/month; imports: ~2.19 MT/month (January 2026 data).
- LPG storage capacity: ~140,000 MT strategic (5 days' demand); individual OMC commercial storage is additional but still limited.
Connection to this news: The OMCs' push for expanded storage directly addresses the structural gap laid bare by the 2026 crisis: India's LPG buffer is far too small relative to import volumes and household dependency, making any sustained Hormuz disruption an immediate domestic crisis.
Underground Rock Cavern Storage — Technology and Strategic Significance
Underground rock cavern (URC) storage is the global standard for large-scale strategic hydrocarbon reserves. In India, both ISPRL (for crude oil) and OMCs (for LPG) use this method. Rock caverns are excavated in stable geological formations and exploit the principle of hydrostatic pressure from surrounding groundwater to keep the stored hydrocarbon in place — no steel liner is required. They are inherently safe (no surface explosion risk), have lower per-unit storage costs at scale compared to above-ground bullet tanks, and are virtually invisible from the surface (militarily harder to target). The US, South Korea, Germany, and Japan have used underground caverns extensively for both crude oil and LPG storage. India's HPCL Mangalore LPG cavern (80,000 MT, commissioned 2025) is among South Asia's largest LPG underground storage facilities.
- HPCL Mangalore LPG cavern: 80,000 MT capacity (commissioned late 2025).
- Visakhapatnam LPG cavern: 60,000 MT capacity.
- Combined strategic LPG storage: ~140,000 MT (~5 days of national demand at current consumption rates).
- Underground crude oil caverns (ISPRL): 5.33 MMT total at Visakhapatnam, Mangalore, and Padur.
- Above-ground bullet tanks (OMCs' normal commercial storage): provide only 2–4 days' additional buffer.
Connection to this news: The OMCs' expansion push is effectively a call to build more URC-based facilities — the technology that ISPRL uses for crude oil — extending the same approach to LPG to create a meaningful strategic buffer rather than a token few days' supply.
Energy Security Policy — IEA Standards and India's Gap
The International Energy Agency (IEA) recommends that member countries maintain a minimum of 90 days of net oil import cover as strategic reserves. India, with Phase I SPR capacity equivalent to approximately 9.5 days of crude consumption, is far below this benchmark. India is an IEA Association Country (since 2017), and while not a full member, it participates in IEA data sharing and emergency response frameworks. Bridging India's strategic petroleum reserve gap is a long-term policy objective that the West Asia conflict has brought into sharp focus. The push by OMCs for more LPG storage is consistent with this broader SPR expansion agenda.
- IEA 90-day strategic reserve requirement: for full members (India is an Associate, not full member).
- India's Phase I crude SPR: ~9.5 days of consumption (5.33 MMT).
- Phase II (Chandikhol + Padur extension): will add 6.5 MMT; still well below 90 days.
- India joined IEA as an Association Country in March 2017.
- Annual crude consumption: approximately 200 million metric tonnes.
Connection to this news: The OMCs' call for expanded LPG storage is one piece of a larger puzzle: India's strategic reserve infrastructure — both for crude and for LPG — remains significantly below the international benchmark, and the 2026 crisis has made the cost of this gap visible.
