L&T Bets Big on Nuclear Energy — Targets 3x to 3.5x Revenue Growth in 5 Years
India's engineering giant is positioning itself at the heart of the country's nuclear power revolution — here's what it means, in simple points.

Larsen & Toubro — India's largest engineering company — has made a bold announcement: it expects its nuclear energy revenues to grow 3 to 3.5 times in just 5 years. This is a big deal, and here's why every Indian should understand what's happening.

First, what is L&T's role in nuclear energy?
L&T is not a newcomer to nuclear energy — it has been supplying critical equipment to India's nuclear plants for decades. The company manufactures reactors, steam generators, pressurisers, and heavy piping that go inside nuclear power plants. Think of it like this: if nuclear power plants are the body, L&T makes the vital organs. It is a critical EPC (Engineering, Procurement & Construction) and manufacturing partner for every single existing nuclear reactor in India. It will NOT own or run nuclear plants — it builds and supplies the critical components and constructs the facilities.

Why nuclear, why now?
Three powerful forces are coming together at the same time. First: India wants to go from 8.8 GW of nuclear power today to 100 GW by 2047 — that's more than 10 times growth. Second: The world is shifting to clean energy, and nuclear is the only 24/7 clean energy source (unlike solar which stops at night or when it's cloudy). Third: Artificial Intelligence and Data Centres are consuming massive amounts of electricity — companies like Google, Microsoft, and Amazon are now signing nuclear power deals globally because they need stable, uninterrupted power. L&T sees all three of these trends as a once-in-a-generation business opportunity.
"Nuclear-related revenue is expected to rise 3 to 3.5 times over the next five years, depending on how quickly projects are executed."

What exactly will L&T do? — The business plan in simple words
L&T has a clear, focused plan with four parts. Part 1 — Build nuclear plants (EPC): L&T will act as a construction and project management contractor for nuclear power plants in India. Part 2 — Make critical parts and export them: It will manufacture reactors, steam generators, and pressurisers at its Hazira (Surat) facility and supply them to nuclear projects in India and globally — competing with GE, Alstom, and Mitsubishi. Part 3 — Small Modular Reactors (SMRs): L&T has received US Department of Energy approval for SMR technology transfer and is in talks with global partners for these smaller, faster-to-deploy nuclear units. Part 4 — No plant ownership: L&T will NOT own or operate nuclear plants — it stays purely in construction, manufacturing, and services. Lower risk, steady fee-based income.

What is a Small Modular Reactor (SMR)? — Explained simply
Simple Explainer
Traditional nuclear plants are massive — they take 10–15 years to build, cost lakhs of crores, and generate 1,000+ MW. SMRs are smaller nuclear reactors — each generating up to 300 MW — that can be built faster, cost less, and be placed in more locations. Think of them as the compact cars of the nuclear world vs the old diesel trucks. The government of India has issued a Request for Proposal (RFP) for Bharat Small Reactors — and L&T is already in discussions with NPCIL (Nuclear Power Corporation of India) for this. L&T has already received US Department of Energy approval to manufacture SMRs — a significant credential.

India's 100 GW nuclear dream — and why it matters
India Macro Story
India currently has 8.8 GW of nuclear power — just about 3% of its total electricity mix. The government's target is 100 GW by 2047 — a more than 10x expansion. To put this in perspective: India needs stable, 24/7 power for its factories, hospitals, data centres, EV charging, and homes — solar and wind alone cannot guarantee this. The Union Budget 2025–26 extended customs duty exemptions on capital goods for nuclear projects until 2035 — a direct policy push to make nuclear cheaper. NTPC (India's largest power company) is also targeting 30 GW of nuclear capacity through joint ventures. L&T sits right at the centre of this national mission as the primary engineering contractor.

L&T's manufacturing advantage — the Hazira factor
Key Asset
L&T's Hazira manufacturing facility in Surat, Gujarat is a critical national asset. Built decades ago, it is one of the only facilities in India capable of manufacturing the heavy, precision-engineered components that nuclear plants need. The important fact: Hazira already has enough capacity to scale up nuclear manufacturing rapidly — without L&T needing to spend thousands of crores on new factories. This means L&T can capitalise on the nuclear boom with relatively low additional capital expenditure — a direct benefit to profitability. The company also has an integrated steel plant and a heavy forging unit that further strengthens its manufacturing capability for nuclear-grade components.

What are the challenges? — A fair discussion
Risks & Challenges
Nuclear projects take a long time. Even with the best intentions, nuclear plants take many years to go from approval to full operation — the 3x revenue target depends heavily on how quickly projects achieve financial closure and execution begins. Technology partnerships needed: L&T is still in preliminary discussions with global nuclear technology providers for SMRs and large reactors — these tie-ups need to be finalised. India still depends on foreign reactor technology (Russia, France, USA) for some reactor types, which creates supply chain complexities. Regulatory clearances for nuclear projects in India are rigorous and time-consuming — any delays can push timelines.

Goldman Sachs and the bigger L&T story
Market View
Goldman Sachs has a bullish view on L&T, specifically pointing to defence, green hydrogen, and nuclear power as key growth drivers. The brokerage projects L&T's Total Addressable Market to grow from ₹1.4 lakh crore in FY26 to ₹3.4 lakh crore by FY35 — more than double. Revenue is forecast to grow at a low-double-digit CAGR with profits at a mid-teen CAGR. Nuclear is a key part of this story but not the only one — L&T is simultaneously growing in defence, data centres, green energy, and infrastructure. The nuclear ambition adds a new long-duration, high-margin revenue stream to an already diversified business.
"We have very good manufacturing capability. Perhaps we are one of the only ones who have the ability to manufacture these reactors, and we also have the full EPC capability to build those plants, including the control system."
— Subramanian Sarma, Deputy MD & President, L&T
The Big Picture — What this means for India
India is on the cusp of a nuclear energy revolution. From 8.8 GW today to 100 GW by 2047 — that's an 11x expansion of clean, 24/7 baseload power. L&T's ambition to triple its nuclear revenues reflects the scale of this national opportunity. This is not just about one company — it's about India building energy independence, reducing carbon emissions, powering AI data centres, and ensuring stable electricity for 1.4 billion people. L&T's Hazira facility, decades of experience building nuclear equipment, US DOE approval for SMR technology, and conversations with global partners position it as India's most credible nuclear engineering partner. If India executes its nuclear ambition — even partially — L&T is a primary structural beneficiary of that journey.
