Listen to the news

Eurozone industrial sentiment has improved to multi year highs, even as energy price swings keep inflation in focus. That mix of steady factory demand and sensitive power costs keeps attention on nuclear energy stocks as a potential long term power source. This article introduces three stocks from the Nuclear Energy Stocks screener that highlight different angles of the theme and may help you decide which ones deserve a closer look.

The stocks covered below are just a starting sample, and the full screen has surfaced 21 more nuclear energy companies with equally compelling stories that are not included in this article. To identify and analyze the highest conviction ideas in this theme, head straight to the Nuclear Energy Stocks screener.

Kirloskar Oil Engines (NSEI:KIRLOSENG)

Overview: Kirloskar Oil Engines is a Pune based manufacturer of diesel and gas engines, gensets, pumps and power solutions that keep critical sites running when the grid fails, including nuclear power plants that rely on its specialized backup power systems, control panels and long term service support.

Operations: Kirloskar Oil Engines generates most of its revenue from its B2B segment at about ₹58,979 million, with smaller contributions from B2C at about ₹11,478 million and Financial Services at about ₹8,932 million.

Market Cap: ₹308.7 billion

Investors looking at nuclear energy as a long term, reliable power source may find Kirloskar Oil Engines interesting because it supplies the backup diesel and gas gensets that nuclear plants and other critical infrastructure depend on when the grid goes down. The recent 192 MW data center order highlights the use of its high capacity systems in mission critical settings beyond nuclear as well. That focus on reliability, service and emissions retrofits sits alongside risks such as reliance on diesel technology, an unstable dividend record and sensitivity to capex cycles and borrowing costs. The mix of theme linked demand, growth ambitions and financial trade offs makes Kirloskar Oil Engines a company that some investors may consider examining more closely in this screener.

Kirloskar Oil Engines is plugged into critical power for nuclear plants and data centers, yet the real story may be how its risks and opportunities stack up beneath the surface.

Larsen & Toubro (BSE:500510)

Overview: Larsen & Toubro is a Mumbai based engineering and construction group that delivers large EPC projects across infrastructure, energy and manufacturing, with its Hi Tech Manufacturing arm supplying custom heavy equipment and systems to nuclear power plants alongside process, defence and aerospace clients. For investors focused on the Nuclear Energy Stocks theme, that specialist nuclear plant design, fabrication and retrofit capability is the clearest link to reactor build, upgrade and maintenance work.

Operations: Larsen & Toubro generates most of its revenue from Infrastructure & Utilities at about ₹1,348.6b, with further contributions from Technology, Platforms & Services at about ₹565.6b, Energy Conventional at about ₹566.8b, Manufacturing & Products at about ₹148.6b, Development Projects at about ₹49.7b and Financial Services at about ₹189.2b.

Market Cap: ₹5,559.2b

Investors eyeing nuclear power often look for pure play reactor builders or fuel suppliers. Larsen & Toubro offers a different angle as a large EPC group with nuclear qualified heavy engineering sitting inside a much broader order book. The company has a multi trillion rupee backlog, growing exposure to clean energy, data centers and grid projects, and a shift toward higher margin tech and digital services that can help support funding for complex nuclear work. At the same time, reliance on government and Middle East contracts, project execution risk and margin pressure in some segments mean future earnings are not guaranteed. For those seeking exposure to nuclear infrastructure within a diversified engineering group, Larsen & Toubro may merit further research.

Growth in Larsen & Toubro’s nuclear and clean energy work could be masking a very different earnings profile behind its huge order book. Scan the analysis report for Larsen & Toubro for the twist most investors might be missing

Bharat Heavy Electricals (BSE:500103)

Overview: Bharat Heavy Electricals is a New Delhi based heavy engineering company that designs and builds large power plants, including supplying key nuclear equipment such as steam generators, turbines, heat exchangers, pumps and valves, alongside a broad portfolio across coal, gas, hydro, solar, transportation, defence and industrial systems.

Operations: Bharat Heavy Electricals generates most of its revenue from Power at about ₹274.3 billion, with Industry contributing about ₹85.7 billion.

Market Cap: ₹1,499.0 billion

For investors focused on nuclear energy, Bharat Heavy Electricals offers direct exposure to reactor build and upgrade activity through its EPC work and heavy equipment supply for nuclear plants, while still being cushioned by a large coal, gas and industrial portfolio. Recent quarterly results showed revenue of ₹79.1 billion and a move from loss to profit, which suggests the order book is supporting better earnings quality. At the same time, a rich valuation and reliance on external borrowing, combined with a board that currently has no independent directors, mean execution and governance are key risks to monitor. If nuclear EPC orders continue to shape the business mix, Bharat Heavy Electricals could become a key stock to track in this theme for investors willing to scrutinize those trade offs.

Bharat Heavy Electricals has an order book that now shows up in revenue of ₹79.1b and a shift from loss to profit. Yet the bigger story may sit in how those contracts reshape risk and reward. Before you move on, scan the 2 key rewards and 1 important warning sign
