India's largest private power companies are increasingly turning their attention to nuclear energy, signalling a major shift in the country's long-term power strategy. After expanding aggressively in thermal and renewable energy, companies including Vedanta Power, Adani Group, Tata Power and Reliance Industries are now positioning themselves to participate in India's ambitious nuclear expansion plans.
The renewed interest comes as the government pushes for greater private sector participation, rising electricity demand driven by artificial intelligence (AI), data centres and electric vehicles (EVs), and an urgent need for reliable clean energy that complements solar and wind power.
Why are power companies looking at nuclear energy?
India's electricity demand continues to rise rapidly, with peak demand projected to approach 300 GW by 2027.
While renewable energy remains central to India's clean energy transition, experts believe solar and wind alone cannot provide uninterrupted electricity because of their intermittent nature.
Unlike renewable sources, nuclear power offers continuous, low-carbon electricity generation with high plant utilisation rates, making it an attractive source of stable baseload power.
As of June 2026, India's installed power capacity included:
-
Solar: 162.15 GW
-
Wind: 57.44 GW
-
Nuclear: 8.78 GW
The wide gap highlights the government's plans to significantly expand nuclear capacity over the next two decades.
Policy reforms have opened the door
Private sector interest has accelerated following the introduction of the SHANTI Act, 2025, which allows greater private participation in India's nuclear power sector and provides a framework governing civil liability.
The legislation supports India's long-term goal of developing 100 GW of nuclear power capacity by 2047.
The government has also launched a ₹20,000 crore Nuclear Energy Mission, aimed at accelerating indigenous reactor development, particularly Small Modular Reactors (SMRs).
Currently, India operates 24 commercial nuclear reactors with a combined capacity of 8,780 MW.
Under the government's roadmap:
-
Nuclear capacity is expected to reach around 22 GW by 2031-32.
-
NPCIL aims to expand capacity to nearly 54 GW by 2047.
-
The remaining capacity is expected to come from state governments, public sector companies, private firms and joint ventures.
Vedanta Power plans major expansion
Vedanta Power has announced plans to expand its total generation capacity to 20 GW, with nuclear energy expected to become an important part of its long-term strategy.
The company currently operates 4,180 MW of thermal power capacity across four plants and has secured around 85% of its coal requirements through long-term domestic linkages.
Reports also suggest US-based Holtec International is exploring collaboration with Vedanta and NTPC for the development of a potential 15 GW Small Modular Reactor pipeline in India.
Adani, Tata Power and Reliance join the race
Several major corporate groups have already outlined their nuclear ambitions.
-
Adani Group plans to develop up to 10 GW of nuclear capacity by 2035 and is evaluating reactor technologies and potential sites.
-
Reliance Industries is assessing investments in both conventional nuclear projects and Small Modular Reactors.
-
Tata Power is working with NPCIL to evaluate nuclear opportunities, with land identified across multiple states for proposed SMR projects.
However, commercial implementation will depend on final regulations under the SHANTI Act, which are currently being drafted.
Why thermal power companies have an advantage
Industry experts believe established thermal power companies are naturally positioned to enter the nuclear sector.
These companies already possess expertise in:
-
Large-scale power generation
-
Engineering and project execution
-
Fuel management
-
Grid operations
-
Maintenance and transmission infrastructure
Many can also leverage existing industrial land, transmission networks and skilled manpower while adapting to nuclear-specific regulatory and safety requirements.
Can nuclear become a profitable business?
Although nuclear power offers long operating life, stable fuel costs and high plant utilisation, profitability is not guaranteed.
The biggest challenge remains the enormous upfront investment required.
For example, Kudankulam Units 3 and 4 have an approved project cost of approximately ₹68,893 crore for 2 GW of capacity.
Private investment will largely depend on:
-
Stable regulatory policies
-
Financing support
-
Clear liability rules
-
Standardised reactor designs
-
Long-term power purchase agreements
Without these factors, commercial viability could remain challenging despite growing demand.
Can India achieve 100 GW by 2047?
India's target of expanding nuclear capacity from 8.78 GW to 100 GW by 2047 represents one of the country's most ambitious infrastructure goals.
Currently, 17 reactors with a combined capacity of 13.1 GW are under construction, but significantly more projects will be required to achieve the target.
Key challenges include:
-
High capital costs
-
Long construction timelines
-
Technology localisation
-
Fuel availability
-
Skilled workforce
-
Land acquisition
-
Public acceptance
-
Regulatory approvals
Experts believe the goal is achievable but will require sustained government support, private investment and coordinated execution over the next two decades.
Why this matters
India's energy transition is entering a new phase where nuclear power is expected to complement renewable energy rather than replace it.
With electricity demand rising sharply due to industrialisation, AI infrastructure, EV adoption and digital services, reliable round-the-clock power is becoming increasingly critical.
For companies like Vedanta, Adani, Tata Power and Reliance, nuclear energy represents a long-term strategic opportunity to diversify beyond thermal and renewable generation while participating in one of India's biggest infrastructure expansion programmes.
