Listen to the news

Oil prices recently weakened after signs of progress in US Iran talks, which takes some heat off traditional fuel markets and brings the focus back to long term electricity sources. That puts nuclear power in India on more investors’ radar as a potential source of steady, large scale energy. This article walks through three promising nuclear related stocks from our India focused screener.

The three Indian nuclear related stocks below are only a sample, and the full screen surfaced 19 more companies with equally detailed narratives that are not covered here.

If you want to go deeper into this theme and identify your own highest conviction ideas, head straight to the Nuclear Energy Stocks screener to filter, analyze, and focus on the nuclear energy opportunities that best fit your approach.

Kirloskar Oil Engines (NSEI:KIRLOSENG)

Kirloskar Oil Engines plugs into the nuclear theme through its power generation and backup systems that support critical facilities, including nuclear related sites, while still drawing most of its strength from a broad engine and equipment portfolio.

Kirloskar Oil Engines runs a diversified industrial engine and power solutions platform across diesel gensets, pumps, microgrids, and related services, with the B2B arm contributing about ₹58,979 million, B2C around ₹11,478 million, and Financial Services roughly ₹8,932 million in revenue, and a market value near ₹314.7b.

For the nuclear energy angle, Kirloskar Oil Engines is less about reactors and more about keeping essential systems powered when the grid does not cooperate. This is exactly where backup gensets and modular energy solutions matter.

"Sustained demand from infrastructure, commercial real estate, and data center development in India, driven by ongoing urban expansion and large infrastructure investments, provides strong, multi-year tailwinds for the core power generation (PowerGen) and industrial engine segments, likely supporting both revenue and earnings growth."

What really shapes the long term payoff for Kirloskar Oil Engines is how one quiet pressure on its capital base and funding costs eventually resolves.

That pressure point is exactly where the story gets interesting, and the full narrative for Kirloskar Oil Engines shows how it could reshape funding costs, capital intensity, and the nuclear angle.

Larsen & Toubro (BSE:500510)

Larsen & Toubro is best known for huge construction and energy projects, but for this nuclear focused screen the interest sits in its Hi Tech Manufacturing arm, which builds critical components and systems for reactors alongside a much broader EPC and services portfolio.

Larsen & Toubro runs a wide mix of infrastructure and energy businesses, with Infrastructure & Utilities generating about ₹1,348.6b in revenue, Energy Conventional around ₹566.8b, Technology, Platforms & Services roughly ₹565.6b, Manufacturing & Products near ₹148.6b, and a market value close to ₹5,323.9b.

"The company's record-high order book (₹6.13 trillion, up 25% YoY) and a rapidly expanding order prospects pipeline, especially in infrastructure (+32%) and hydrocarbon (more than doubled), position L&T to capture sustained project inflows amid ongoing urbanization, rising infrastructure investment, and supportive government initiatives; this is likely to drive multi-year revenue visibility and growth."

For investors tracking nuclear linked projects, what happens to one still forming mix between higher tech work and tighter project margins could matter a lot.

That margin mix is exactly where the story starts to shift, and the full narrative for Larsen & Toubro shows how higher tech work could accelerate value while project risk quietly reshapes returns.

Bharat Heavy Electricals (BSE:500103)

Bharat Heavy Electricals is a large power equipment supplier that builds entire coal, gas, hydro and nuclear plants, along with turbines, steam generators and control systems for heavy industry. The Power segment produces about ₹274.3b of revenue versus ₹85.7b from Industry, and the stock carries a market value near ₹1,484.2b.

Nuclear linked EPC and equipment for reactors is where Bharat Heavy Electricals plugs into this theme, even though coal, gas and other power work still drive most of its ₹274.3b Power segment. Recent earnings turned to a profit and the stock trades on a P/E of about 61x. The nuclear order book could therefore be significant, depending on how one unseen pressure develops.

That unseen pressure is where Bharat Heavy Electricals gets interesting, and the analysis report for Bharat Heavy Electricals teases out how the nuclear order book could tilt the story.
