At the same time, coal has become harder to defend as a long-term baseload due to climate pressure, financing constraints, and geopolitical risk. Meanwhile, batteries remain expensive at grid scale, and hydropower faces ecological and climate limits. Consequently, nuclear energy has re-emerged not as ideology, but as a mathematical necessity. Yet India’s older framework—built around a state monopoly and later complicated by liability uncertainty—could not scale. Therefore, Parliament moved toward a new, consolidated statute widely referred to as the SHANTI Bill 2025, with the Government emphasising that nuclear safety and strategic control remain non-negotiable.

Why the Old Nuclear Laws Could Not Scale Energy

The Atomic Energy Act of 1962 was designed for a different India: a strategic, security-first environment where the State maintained complete control over nuclear assets. That model ensured sovereignty and safety. However, it also locked nuclear power inside a narrow public-sector bandwidth. As a result, nuclear capacity stayed small even as India’s electricity system expanded rapidly.

Interpretation: The system produced a paradox—high performance, low scale. In other words, nuclear technology did not fail. The legal and financial architecture did.

How the 2010 Liability Law Blocked Investment

The Civil Liability for Nuclear Damage Act, 2010, addressed public anxiety after Fukushima-era debates. However, it left supplier-risk issues politically contested and commercially complex. Consequently, insurance and vendor participation remained constrained. The 2025 framework seeks to rationalise liability, improve insurability, and create clearer pathways for investment—while keeping operator liability strict.

Data Table 2: Liability economics—what changes in practice

Interpretation: The strategic trade-off is clear: the 2025 model attempts to make nuclear projects financeable and scalable. Therefore, the real question becomes whether the rule-making phase preserves transparency and victim-centric safeguards while still attracting capital.

India’s Clean Energy Demand Has Changed

India’s energy problem is no longer just “more electricity.” Instead, it is “more clean electricity, reliably, at all hours.” AI data centres, industrial clusters, and hydrogen production all demand firm power. Consequently, a clean grid needs a combination of variable renewables and firm sources.

Data Table 3: Why reliability now matters as much as volume

Interpretation: Nuclear’s advantage is not dominance. Instead, it is reliability. It enables renewables to scale without forcing the grid to fall back on coal for stability.

Can Nuclear Energy Fulfil India’s Clean Energy Demand in the Future?

Nuclear energy can meet a meaningful share of future clean demand, but it cannot carry the whole system alone. Even under ambitious expansion, nuclear typically remains a minority share of total electricity. However, it can still become the backbone for firm clean power if India scales capacity, shortens project cycles, and stabilises financing.

Data Table 4: Contribution scenarios (illustrative, policy lens)

Interpretation: Nuclear can help India meet clean-energy demand by providing a dependable baseload and reducing coal dependence. Yet it works best as a foundation under a renewables-and-storage superstructure.

Why Private Participation Became Necessary

Nuclear projects require large upfront capital and long timelines. Therefore, a purely public model struggles to scale fast enough. The 2025 framework seeks to open participation under licensing while preserving State control over strategic materials and spent fuel custody.

What the India New Nuclear Energy Act 2025 Changes

The consolidated law aims to modernise governance across licensing, safety authorisation, liability architecture, dispute resolution, and investment participation. Importantly, the Government has reiterated in Parliament that it retains full control over strategic materials, spent fuel, and non-negotiable safety standards, while also presenting a long-term capacity roadmap and newer concepts like SMRs and “Bharat Small Reactors.”

Data Table 5: Old framework vs new direction (high-level)

Interpretation: The Act does not privatise nuclear sovereignty. Instead, it attempts to scale civilian nuclear infrastructure by widening participation and consolidating governance—while the State keeps control over the most sensitive layers.

Timeline: How Repeal Became Inevitable

Final Interpretation

• Performance was not the problem. The legal-and-financial model was.
• Monopoly structures capped scale even when reactors performed reliably.
• Liability uncertainty raised risk premiums and discouraged participation.
• India’s clean-energy future needs firm clean power alongside renewables and storage.
• The India New Nuclear Energy Act 2025 attempts to make scaling possible while keeping sovereign controls intact.

Bottom line: Nuclear energy will not supply all of India’s clean-energy demand. However, without nuclear, India will struggle to meet that demand reliably and at industrial scale.
