Three Indian nuclear energy stocks position as data center and grid power suppliers amid escalating electricity demand.
Rising inflation concerns and energy-price volatility are drawing investor attention to nuclear energy stocks across the uranium production, enrichment and reactor operations value chain. These companies sit at the intersection of energy security, inflation-sensitive input costs and long-term power demand growth. Three Indian stocks illustrate different segments of this narrative.
**Kirloskar Oil Engines**
Kirloskar Oil Engines, a Pune-based manufacturer of diesel engines, gensets and pumps, supplies backup and prime power solutions to infrastructure, data centers, telecom, manufacturing, agriculture and defense sectors across India and internationally.
The company generates ₹56.9 billion from its B2B segment, ₹11.4 billion from B2C and ₹8.8 billion from Financial Services. Domestic revenue dominates at ₹68.0 billion, with ₹9.0 billion from exports. Revenue growth is being driven by rising demand for reliable backup power as Indian cities expand, data centers proliferate and grid reliability remains uneven. A 192 MW order from the HyperNext data center and healthy FY2025–26 earnings suggest that higher-capacity gensets are gaining traction and that further earnings growth is likely. However, investors must weigh the company's heavy reliance on diesel technology, margin pressures in parts of its B2C business and capital deployed in underperforming segments.
**Larsen & Toubro**
Larsen & Toubro, a Mumbai-based engineering and construction group, executes large-scale infrastructure, energy and industrial projects, with exposure to nuclear energy, defense, green hydrogen and aerospace.
Revenue is distributed across Infrastructure & Utilities (₹1,348.6 billion), Energy—Conventional (₹566.8 billion), Technology, Platforms & Services (₹565.6 billion), Manufacturing & Products (₹148.6 billion), Financial Services (₹189.2 billion) and Development Projects (₹49.7 billion). The company benefits from a record order book, growing exposure to green energy, data centers and AI infrastructure, and rising revenue and net income through FY2026. Offsetting these strengths are heavy dependence on government and Middle East projects, project margin pressure, reliance on external borrowing and execution risk from managing hundreds of thousands of site workers.
**Bharat Heavy Electricals**
Bharat Heavy Electricals, a New Delhi-based engineering group, designs and manufactures power plant equipment and industrial systems across coal, gas, hydro and nuclear power, as well as rail, transmission, defense, aerospace, e-mobility and energy storage.
The company generates ₹274.3 billion from its Power segment and ₹85.7 billion from Industry. It benefits from participation in large power and industrial buildouts and emerging areas like green hydrogen through a partnership with thyssenkrupp nucera. Earnings growth over the past year was substantial, with recent quarterly results shifting from loss to profit. However, the stock trades on a rich valuation multiple with analyst targets below the current share price, suggesting high market expectations. Governance concerns include a young board lacking independent directors, combined with reliance on external funding.
The three stocks highlighted represent only a portion of the broader Nuclear Energy Stocks screener covering 20 additional companies with compelling nuclear energy and power grid narratives. Each reflects distinct exposure to India's expanding energy infrastructure and the demand from data centers and grid modernization driving the sector.
