BharatNotes What is Strategic Petroleum Reserve?
A Strategic Petroleum Reserve (SPR) is a government-maintained emergency stockpile of crude oil designed to insulate a nation against sudden supply disruptions, geopolitical conflicts, natural disasters, or sharp price spikes. Because India imports the overwhelming majority of its crude — import dependence stood at roughly 88% in FY2024-25 — such a buffer is central to its energy security strategy.
The Government of India approved building strategic reserves and a Special Purpose Vehicle in 2004. Indian Strategic Petroleum Reserves Limited (ISPRL), incorporated in June 2004, was made a wholly owned subsidiary of the Oil Industry Development Board (OIDB) and builds the reserves in underground rock caverns — a low-cost, low-evaporation, secure storage method.
Phase I: locations and capacity
Phase I created total storage of 5.33 million metric tonnes (MMT) across three coastal sites, completed and filled:
| Location | State | Capacity (MMT) |
|---|---|---|
| Visakhapatnam | Andhra Pradesh | 1.33 |
| Mangaluru | Karnataka | 1.50 |
| Padur | Karnataka | 2.50 |
| Total | 5.33 |
This Phase-I capacity provides roughly 9.5 days of India's crude oil requirement based on consumption patterns (as per ISPRL/Ministry of Petroleum). Combined with commercial stocks held by oil marketing companies, India's total cover has been reported at around 74 days — still short of the IEA's 90-day net-import standard.
Phase II expansion
To deepen the buffer, the government has moved to add two more facilities totalling 6.5 MMT — Chandikhol, Odisha (4 MMT) and an additional Padur, Karnataka (2.5 MMT) — proposed under a public-private-partnership (PPP) model to reduce budgetary outlay. These remain under development. Once Phase II is operational, total SPR capacity would rise to about 11.83 MMT, materially extending strategic cover.
Significance
- Cushions supply shocks: A reserve lets India keep refineries running during embargoes, wars, or shipping-lane disruptions (e.g., Strait of Hormuz risks).
- Price arbitrage: India filled reserves cheaply during the 2020 oil-price crash, demonstrating the buffer's economic value.
- Macroeconomic stability: Crude is India's largest import; price spikes widen the current-account deficit and pressure the rupee, so a reserve indirectly supports external-sector stability.
UPSC angle
For Prelims, remember: ISPRL (OIDB subsidiary), three Phase-I sites, underground rock caverns, and the IEA's 90-day recommendation (India is an IEA Associate Member since 2017, not full). For Mains GS3, frame SPR within energy security, import-dependence reduction, and strategic autonomy; for GS2, link to India–IEA cooperation and West Asia geopolitics. Cross-link with current-affairs on crude prices and the energy-transition debate.
