How Can Solar Power Help Reduce India's Reliance on the Strait of Hormuz?

What happens to India's economy the morning a tanker war shuts down a 33 kilometre stretch of water between Oman and Iran?

Hostility from Iran caused the Strait of Hormuz to be closed to commercial shipping for several weeks in early 2026. India had to quickly find alternative routes for crude oil shipments, also accounted for natural gas under the Essential Commodities Act, and operated its refineries beyond the rated capacity to maintain the supply of diesel and petrol. 

Nearly half of crude oil imports of India transit through that corridor. The cost that India pays in freight insurance import, and macroeconomic uncertainty is huge. And, that cost is almost completely in terms of oil. 

So, can solar power and India’s energy security really come together to reduce this dependence or is the link between solar panels and tanker routes too indirect?

Why Does the Strait of Hormuz Matter So Much for India's Energy Security?

The Strait of Hormuz is 33 kilometres wide at its narrowest navigable point. Through that gap, nearly 20 million barrels per day of crude oil, close to 34% of global crude trade, passed in 2025. It is the primary export route for oil produced by Saudi Arabia, the UAE, Kuwait, Qatar, Iraq, Bahrain, and Iran.

The physical alternatives are limited: Saudi Arabia's East to West pipeline to Yanbu handles up to 5 mb/d; the UAE has a bypass pipeline to Fujairah rated at 1.8 mb/d. Neither comes close to absorbing the full volume.

For India specifically, the impact of the Strait of Hormuz runs through three channels:

1. Physical supply: Around 60 to 65% of India's crude imports move via this corridor. Any obstruction shortens the queue of crude reaching refineries within weeks.

2. Price: Even brief incidents are enough to send Brent above USD 120 per barrel. India depends on foreign sources for nearly 88% of its crude oil, meaning any sudden price changes can affect various fuels such as petrol, diesel LPG, and aviation fuel.

3. Logistics cost:If tankers have to be rerouted by going around the Cape of Good Hope it would need an extra 15+ days and as a consequence freight charges and marine insurance premiums would increase.

India’s structural vulnerability is high: risk scores of 4.9 to 5.3 (India and South Korea) reflect high reliance on fossil fuel imports via Hormuz. Meaning, no short term logistics fix can fully resolve it.

How Dependent Is India on Imported Oil and Why Is That a Strategic Risk?

India's energy import dependence has deepened alongside economic growth.

• 232.5 million tonnes of crude oil imported in FY2023-24

• Crude import dependence: 87.7%

• Domestic production has stagnated for over a decade

Supplier concentration matters: over 60% of imports are from Persian Gulf countries. Diversification to Russian crude helps, but geopolitical pressure can constrain availability, as in early 2026.

LNG adds another layer of risk. Two thirds of regional LNG imports pass through the Strait, used for peaking, base load, and industrial processes.

India’s strategic petroleum reserves cover 9.5 days of crude; commercial stocks bring total cover to 64.5 days, still below the IEA’s recommended 90 day minimum.

Can Solar Power Directly Reduce India's Oil Dependence?

Solar vs oil dependency in India cannot be about a direct substitution.

• Solar generates electricity.

• India’s oil consumption is primarily transport fuels, LPG, and petrochemicals.

Oil consumption breakdown:

• Transport fuels: Majority

• Petrochemicals, lubricants, LPG: Remaining bulk

• Oil-fired power: Minor and declining

Impact: the power system. 

• Solar displaces coal, or gas fired generation, 

• Reducing imports of fossil fuels used for electricity.

The indirect impact: As electricity consumption grows in transport, agriculture, and industry, solar becomes upstream of oil displacement.

Key takeaway: Solar reduces oil imports indirectly over the medium to long term, not immediately.

How Solar Improves Energy Security Indirectly?

1. Shrinking the import surface – India’s 484.82 GW installed power capacity now has 50%+ renewables. Solar reduces imported gas demand, weakening Hormuz’s leverage over electricity.

2. Price resilience – Solar’s zero fuel cost insulates industry from global energy volatility.

3. Strategic leverage – Non fossil electricity capacity strengthens current account resilience and reduces economic disruption during crises.

How Can Solar Reduce Diesel Dependence Across Agriculture, Commercial Operations, and Backup Power?

The PM KUSUM scheme replaces diesel irrigation pumps with solar alternatives.

• Targets 34,800 MW of solar by March 2026

• FY2024-25: 4.4 lakh new solar pumps, 2.6 lakh solarised existing pumps

Impact: 

• Hundreds of thousands of tonnes of diesel saved annually, diesel that otherwise transits the Strait of Hormuz.

Commercial & industrial sectors: solar plus storage is replacing diesel gensets for backup. Data centres, hospitals, telecom towers, and factories are increasingly adopting these systems.

Why Are Storage and Grid Modernisation Necessary If Solar Is to Strengthen Energy Security?

Reliable energy security requires:

1. Storage – 43 GWh battery storage under funding, 11,870 MW pumped storage under construction

2. Transmission – Six states produce 85% of wind and solar; grid investments are essential to deliver power nationwide

3. Demand flexibility – EV charging, industrial load shifting, and demand response programs reduce storage needs

How Does Solar Support India’s Longer Term Shift Away from Imported Fossils Through Electrification?

Electrification is the key:

• Railways: 100% electrification reduces diesel freight/pax demand

• EVs and green hydrogen: Expected 5 MT green hydrogen by 2030; reduces crude import costs by ₹1 lakh crore/year, cuts 3.6 Gt CO₂ by 2050

• Distributed solar: Cuts LNG import dependence for peaking and grid support

Energy independence via solar is a gradient, more electrification powered by solar reduces Hormuz’s strategic leverage.

What Are the Economic Benefits of Solar for India in a Strait of Hormuz Risk Scenario?

Fixed cost solar also improves industrial tariff visibility and acts as geopolitical risk insurance.

How Do India’s Renewable Energy Goals Fit into a Broader Energy Security Strategy?

India renewable energy goals 2030 double as an energy security strategy. 

• Non fossil sources already exceed 50 percent of installed capacity. 

• Solar has grown from 3 GW to 129 GW since 2014. 

At current pace, capacity may reach about 378 GW by 2030, so faster grid expansion, storage, and transmission are essential.

What Are the Limits of Solar in Reducing Strait of Hormuz Dependence?

• Sectoral limitation: Transport fuels and petrochemicals remain reliant on crude

• Intermittency: Requires storage for round the clock reliability

• Transmission bottlenecks: Curtailment limits effective energy delivery

Decadal electrification timelines: EVs, green hydrogen, rail electrification take 15 to 25 years to impact crude demand.

What Complementary Measures Must India Combine with Solar to Reduce Hormuz Exposure?

What Should Businesses and Power Intensive Sectors Take Away from This Shift?

• Captive solar provides partial insulation from grid tariff volatility

• Solar plus storage competes economically with diesel gensets

• Hybrid models reduce diesel dependency while ensuring reliability

• Export-oriented industries benefit from lower embedded carbon footprints

Risk management: 

Solar reduces exposure to energy price volatility, even if transport/process heating remains fossil fuel dependent.

Final Takeaway: Can Solar Meaningfully Reduce India’s Reliance on the Strait of Hormuz?

Solar power and India’s energy security converge through:

• LNG displacement

• Diesel reduction in agriculture

• Shrinking electricity import dependence

• Enabling electrification

• Laying the foundation for green hydrogen

Solar, storage, electrification, transmission, and policy have to align to mitigate the Strait of Hormuz dependency.

Every year India delays renewable expansion is another year the economy remains financially hostage to a 33 kilometre stretch of water. 

As an Independent Power Producer, we enable industries to transition toward cost-efficient solar and hybrid energy models that improve energy security and reduce dependence on grid volatility.
