India’s Nuclear Power Ambitions: Private Sector’s Role Post-SHANTI Act
By Business Desk
India targets 100 GW nuclear power by 2047. The SHANTI Act opens the sector to private players to bridge a 46 GW gap, but challenges remain.
India’s nuclear reactor construction, long an exclusive government domain, has now opened to private companies through the SHANTI Act. This significant legislative shift supports India’s ambitious target of achieving 100 GW nuclear power capacity by 2047.
Currently, India operates 8.78 GW of nuclear power, with ongoing projects projected to elevate this capacity to 22 GW by 2031-32. The Nuclear Power Corporation of India Ltd (NPCIL) anticipates contributing 32 GW by 2047, bringing its total share to 54 GW.
Bridging the Capacity Shortfall
A substantial 46 GW gap remains, which must be filled by other public sector companies, private players, and joint ventures. Meeting the 100 GW target is critically dependent on attracting considerable private capital.
However, private investment faces significant challenges due to the inherently capital-intensive nature of nuclear power. Tata Consulting Engineers (TCE) estimates the cost at over $3 million per MW, meaning a 2,000-MW facility could require approximately $6 billion.
Such high investment thresholds naturally limit participation to only a few large corporate groups. Long construction periods, typically 10-12 years, further complicate financing, as developers incur debt servicing costs for years before generating revenue.
Addressing Commercial Viability and Regulation
Delays in land acquisition, approvals, and construction directly escalate power costs, underscoring the necessity for clear financing terms and robust risk-sharing frameworks. While the SHANTI Act has removed legal barriers, the commercial viability for private players remains uncertain.
Industry stakeholders are actively seeking clarity on crucial aspects like nuclear tariff fixation, expected returns, and the financial and technical qualifications required for operators. Specific details regarding fuel arrangements, reprocessing, and exclusion zones are also pending.
These factors are vital for securing project financing, as private companies need assurance about electricity buyers and long-term power purchase agreements. The mechanism for reflecting costs in tariffs is also critical, especially given the competitive landscape with falling renewable energy prices.
Amit Sharma of TCE emphasized the government’s essential role in guaranteeing a steady fuel supply for private projects. He also advocated for a more independent regulatory body, moving beyond the Atomic Energy Regulatory Board, to enhance sector transparency and trust.
Sharma suggested that the Department of Atomic Energy (DAE) should focus on strategic objectives, allowing the private sector to lead electricity generation, similar to reforms seen in the space sector. Access to facilities like the Bhabha Atomic Research Centre for technology testing could also foster private participation.
Small Modular Reactors: A Strategic Entry Point
Small Modular Reactors (SMRs) could offer a more accessible entry point for private investment into the sector. The Bhabha Atomic Research Centre (BARC) is currently developing 220-MW and 55-MW SMRs, with the government setting a target for five indigenous SMRs by 2033.
Although still substantial investments, such as Rs 5,960 crore for a BSMR-200, their smaller size enables different commercial models. These SMRs are envisioned for replacing fossil-fuel capacity, providing captive generation for industries, and supporting off-grid applications, potentially diversifying the nuclear energy landscape.
