The Hormuz wake-up call and India’s nuclear moment

One of the most consequential energy signals of 2026 has come not from New Delhi or Mumbai, but from the narrow waterway between Iran and Oman. Disruptions around the Strait of Hormuz have exposed a structural vulnerability that diversification efforts have not yet eliminated. India imports more than 88 per cent of its crude, with roughly half transiting the strait. The exposure extends further. India is the world’s second-largest LPG importer, with around 60 per cent of domestic consumption import-dependent and about 90 per cent of those imports moving through Hormuz. A large share of India’s LNG supplies also passes through this chokepoint. When Hormuz tightens, freight costs rise, the rupee comes under pressure and inflation risks escalate. The message is clear: India’s energy-security challenge remains deeply externalised.

In that context, nuclear power merits renewed strategic attention. It offers attributes that recent disruptions have made impossible to ignore: reliability, scale and low-carbon firmness. Solar in India operates at roughly 21 per cent capacity utilisation and wind at about 25 per cent. Battery storage remains important, but is limited in duration and vulnerable during extended periods of low sunshine or weak wind. A rapid move away from fossil fuels may also shift strategic dependence towards critical minerals. Nuclear is different. It typically operates at capacity factors above 85 per cent, and a nuclear megawatt can deliver several times the annual electricity generated by a solar megawatt

The advantage is not only in output, but also in system value. A gigawatt of solar typically requires several thousand acres; a gigawatt of nuclear requires far less land and operates for 60 to 80 years, compared with 20 to 25 years for most renewable assets and still shorter economic lives for batteries. Nuclear can also strengthen grid stability by providing firm power and system inertia as variable renewables rise to higher shares in the generation mix. Beyond electricity, it can supply high-temperature process heat for refining, fertilisers and green hydrogen applications for which few low-carbon alternatives are currently viable at scale. For hyperscale data centres, industrial clusters and coastal desalination, nuclear remains uniquely relevant.

Against this backdrop, US nuclear delegation May 2026 visit to India carried unusual weight. It brought senior American nuclear executives together with senior Indian policymakers. The timing mattered. It followed the SHANTI Act, which addressed the supplier-liability architecture that had long deterred American vendors. The convergence of India’s legal readiness, American commercial interest and maturing technology creates the most credible opening for bilateral civil nuclear cooperation in two decades.

It is evident that energy security and climate strategy can no longer be discussed seriously without nuclear power. Our “Atoms for Net-Zero” paper, developed with the US-India Business Council, estimates that achieving 100 GW of nuclear capacity by 2047 would require annual additions of roughly 4 to 5 GW from today’s base. That scale-up will require more than legislative intent. It will need accelerated fuel-cycle expansion, a broader uranium-supply strategy, commercial progress on the Fast Breeder Reactor programme and Stage-III reactor pathways, and a major expansion of India’s nuclear workforce. The SHANTI Act is a necessary enabler, but not a sufficient one. The next 18 months will require coordinated action from the Department of Atomic Energy, the Atomic Energy Regulatory Board and other relevant agencies, particularly on licensing and project execution.

Three strategic questions now sit squarely before policymakers

The first is tariff design and financing

Nuclear is a long-life asset class with capital requirements of roughly USD 2–6 billion per gigawatt and operating lives that extend beyond six decades. That profile requires financing instruments aligned to infrastructure logic rather than merchant-power assumptions. Mechanisms such as contracts for difference and viability gap funding could help de-risk early projects. Over time, tariff rationalisation will also be needed to ensure a more balanced comparison between nuclear and renewable energy, particularly when system reliability and land use are taken into account. The SHANTI Act creates room for a more tailored tariff approach; the test now is how quickly that flexibility is translated into bankable projects.
The second question is licensing

If India is serious about scale, the regulatory pathway must become more predictable, standardised and replicable. The Atomic Energy Regulatory Board should consider a dedicated framework for small modular reactors, including provisions for design certification, that can be standardised across sites and reused across repeat builds. Without such a pathway, deployment will remain episodic rather than programmatic
The third question is fuel security

Until Fast Breeder and Stage-III reactors reach commercial maturity, India will need to manage a dual – track strategy : strengthen the domestic foundation while securing international supply partnerships. India’s PHWR (Pressurised Heavy Water Reactor) fleet and Prototype Fast Breeder Reactor provide a strong strategic base, but future reactor classes, including advanced and Generation-IV SMRs, will require investment in enrichment and precision engineered fuel fabrication (especially for some accident proof fuels like TRISO) capabilities well before deployment. In parallel, front-end supply arrangements with partners such as Kazakhstan, Canada and others, will remain important. Yet long-term dependence on imported fuels especially HALEU (High-Assay Low-Enriched Uranium) for advanced reactors would be strategically unwise

India’s proposition to American and allied capital rests on three strengths. First, demand exists at meaningful scale. Industrial off takers across sectors like refining, steel, aluminium, data centres and green hydrogen are beginning to explore first-of-a-kind SMR deployments for captive use. Second, India’s heavy engineering base brings more than five decades of nuclear-grade manufacturing and fabrication capability, an industrial foundation that few emerging markets can match. Thirdly, India offers the prospect of programme-scale deployment rather than isolated demonstration projects. For investors and technology providers, that distinction matters.

The most useful precedent is not rhetorical; it is institutional. Nuclear should adapt the scale-up logic that helped solar move from ambition to execution: standardised contracting, programmatic pipelines, pre-cleared sites and regulatory visibility. In India’s case, that could mean serial deployment of 700 MW PHWRs, BSR (Bharat Small Reactors) and, over time, Fast Breeder Reactor and other advanced designs; faster approval pathways for standardised foreign technologies that meet international norms; designated nuclear zones; and long-duration tariff certainty. The principle is straightforward: scale follows standardisation.

The disruptions around Hormuz and the recent US nuclear delegation have together created a strategic opening that earlier nuclear cycles did not enjoy. The investment case is clearer, the legal architecture is more credible, and the geopolitical logic is stronger. What remains is the regulatory and execution machinery to convert intent into capacity. India’s nuclear moment has arrived. The policy system now needs to act with corresponding urgency.
