The Core Argument
The West Asia conflict of 2025-26, with its threat to Strait of Hormuz transit and actual disruptions to LPG supply chains, has reinvigorated debate about the resilience of India’s energy mix. The editorial examines whether India can — in the medium term — compensate for West Asian oil and gas supply disruptions by accelerating coal-based generation and advancing its nuclear power programme, while continuing the renewables transition. It concludes that a temporary coal bridge + accelerated nuclear + sustained renewables is the realistic energy security formula, but cautions that it must not become a permanent excuse to delay the clean energy transition.
India’s Current Energy Mix — 2025-26
Electricity Generation
| Source | Share of Generation |
|---|---|
| Coal | ~72% |
| Renewables (solar+wind+hydro) | ~22% |
| Nuclear | ~3% |
| Gas | ~3% |
| Oil | <1% |
Primary Energy
| Source | Share of Primary Energy |
|---|---|
| Coal | ~54% |
| Oil | ~28% |
| Natural gas | ~6% |
| Renewables | ~8% |
| Nuclear | ~1% |
| Biomass/traditional | ~3% |
India is the world’s 3rd largest oil importer (after China and the USA) — importing ~5 million barrels/day in 2025-26.
The Hormuz Vulnerability
Strait of Hormuz — The Critical Chokepoint
| Feature | Detail |
|---|---|
| Width | ~39 km at narrowest; navigable lanes of 3 km each direction |
| Transit | ~20 million barrels/day (about 20% of global oil trade) |
| Dependents | India, China, Japan, South Korea, Pakistan |
| India dependency | ~80-85% of oil imports transit Hormuz |
| Alternatives | None fully viable; Cape of Good Hope adds 2-3 weeks |
In 2025-26, Iran’s threats to close the Strait — following U.S. naval operations and vessel seizures — caused:
- Brent crude: Spike to $110-120/barrel (from ~$80 baseline)
- LPG prices: 40-50% increase in global spot markets
- Insurance premiums: War risk premiums on tankers up 5-10x
- India’s import bill: Estimated additional ₹80,000-1,00,000 crore annualised impact
Option 1 — Coal as a Bridge Fuel
India’s Coal Situation
India is the world’s 2nd largest coal consumer (after China) and the 2nd largest importer of coal. However, India also has vast domestic reserves:
| Indicator | Figure |
|---|---|
| Proved coal reserves | 361 billion tonnes (7th globally) |
| Annual coal production | ~1,000 MT (FY2025-26) |
| Annual coal consumption | ~1,100+ MT |
| Import dependence (coking coal) | ~85% |
| Import dependence (thermal coal) | ~25-30% |
Key advantage: Thermal coal for electricity generation is partly domestically sourced — unlike oil, which is nearly 90% imported. A Hormuz disruption does not directly threaten India’s coal supply (most coking coal imports come from Australia/Indonesia — different maritime routes).
The Coal Expansion Option
Under energy emergency scenarios, India can:
- Increase coal plant PLF (Plant Load Factor): Average thermal PLF is ~63-65%; can be pushed to 75-80%
- Accelerate pit-head generation: Build new capacities near coal mines in Jharkhand, Chhattisgarh, Odisha
- Delay retirement of aging units: Some plants slated for decommissioning can be retained as emergency reserves
Problem: Higher coal use → higher CO₂ emissions → contradicts India’s NDC commitments (45% emissions intensity reduction by 2030). India must navigate this as a temporary emergency measure with sunset clauses.
Option 2 — Nuclear Power
India’s Nuclear Programme
| Indicator | Current |
|---|---|
| Installed nuclear capacity | ~7.5 GW (as of 2026) |
| Plants operational | NPCIL plants: Tarapur (Maharashtra), Rawatbhata (Rajasthan), Kudankulam (Tamil Nadu), Kaiga (Karnataka), Narora (UP), Kakrapar (Gujarat) |
| Under construction | Kudankulam Units 3&4; PFBR Kalpakkam (500 MW) |
| 2031-32 target | 22.5 GW (government target — aggressive) |
| NDC target | 100 GW nuclear by 2047 |
The Nuclear Scale-Up Case
- Nuclear power is dispatchable (unlike solar/wind) — runs 24/7, weather-independent
- Zero fuel import dependency for uranium from diversified sources (Kazakhstan, Canada, Australia)
- Lifetime carbon footprint comparable to wind power
- PFBR (Prototype Fast Breeder Reactor) at Kalpakkam — if operational, starts India’s thorium cycle — India has world’s 3rd largest thorium reserves
Nuclear Challenges
| Challenge | Detail |
|---|---|
| Long lead time | 10-15 years from sanction to commissioning |
| Cost | ₹8-12 crore/MW (vs. ₹4-6 crore/MW for solar) |
| Nuclear liability | Civil Liability for Nuclear Damage Act (CLNDA) 2010 — deters foreign vendors |
| Uranium import | India importing uranium under India-specific safeguards (2008 NSG waiver) |
| Public acceptance | Kudankulam protests showed community opposition challenge |
Option 3 — Renewables (The Long-Term Solution)
| Renewable | 2025-26 Capacity | 2030 Target | Status |
|---|---|---|---|
| Solar | ~220 GW | 280 GW | On track |
| Wind | ~55 GW | 140 GW | Behind schedule |
| Hydro (large) | ~47 GW | 70 GW | Limited potential |
| Green hydrogen | ~0.5 GW equivalent | 5 MMT production | Early stage |
Limitation: Solar and wind are intermittent — cannot replace dispatchable fossil fuel capacity 1:1 without massive battery storage. Battery storage technology is cost-declining but not yet at scale for grid backup.
India’s Strategic Energy Choices
Optimal Mix for Energy Security
| Scenario | Coal | Nuclear | Renewables | LNG/LPG imports |
|---|---|---|---|---|
| Current (2026) | 72% | 3% | 22% | 3% |
| 2030 target | 55% | 5% | 35% | 5% |
| Emergency (Hormuz closure) | +5-8% temporarily | Same | Same | Reduce |
| Long-term 2047 | 30% | 25% | 45%+ | <5% |
Strategic Petroleum Reserve (SPR) — India’s Buffer
India’s SPR stores crude oil at three locations:
| Location | State | Capacity |
|---|---|---|
| Visakhapatnam | Andhra Pradesh | 1.33 MMT |
| Mangaluru | Karnataka | 1.5 MMT |
| Padur | Karnataka | 2.5 MMT |
| Total | ~5.33 MMT (~12 days import) |
Target: Expand to 15-16 MMT (30+ days). India is building Phase II (Chandikhol, Rajkot).
