India's Nuclear Future Cannot Wait: The Climate Challenge Is Bigger Than Ever

Introduction

India stands at a defining moment in its energy transition. As one of the world's fastest growing major economies, the country faces an enormous challenge. It must provide reliable electricity to a rapidly expanding population while simultaneously reducing greenhouse gas emissions to meet its climate commitments.

For years, renewable energy has been at the center of India's clean energy strategy. Solar and wind power have witnessed remarkable growth, making India one of the global leaders in renewable capacity addition. Yet, renewables alone cannot meet the country's long term energy needs because they depend heavily on weather conditions and require large scale storage solutions that remain expensive and technologically challenging.

This is where nuclear energy has returned to the national conversation. The Government of India has set an ambitious target of achieving 100 GW of nuclear power capacity by 2047, a dramatic increase from the current installed capacity of around 7.5 GW. Such an expansion would transform India's energy mix and strengthen its energy security while supporting the country's climate goals.

However, achieving this vision requires overcoming policy, legal, financial, and geopolitical challenges that have constrained India's civil nuclear programme for more than a decade.

Interestingly, the discussion around nuclear energy is no longer limited to electricity generation. Recent geopolitical developments, especially after Operation Sindoor and the evolving regional security environment, have strengthened the connection between India's civil nuclear programme and its broader strategic interests. Today, nuclear energy represents not only a climate solution but also an important pillar of national security and technological self reliance.

Why Nuclear Energy Has Returned to the Spotlight

The urgency surrounding nuclear energy is driven by several factors that are reshaping global and domestic energy policies.

India's electricity demand is expected to increase significantly over the next two decades as industrialization accelerates, electric vehicles become more common, and urbanization continues at a rapid pace. Meeting this demand exclusively through fossil fuels would make it nearly impossible to achieve the country's climate commitments under international agreements.

Although renewable energy has expanded rapidly, solar panels do not generate electricity at night, and wind turbines produce variable output depending on weather conditions. Battery storage technologies are improving but remain costly for supporting an electricity system of India's scale.

Nuclear power addresses this challenge by providing continuous, round the clock electricity generation with extremely low carbon emissions during operation. Unlike coal based power plants, nuclear reactors produce electricity without releasing carbon dioxide into the atmosphere during normal operation.

This makes nuclear energy an essential source of stable baseload power that complements renewable energy rather than competing with it.

Several developed economies have also reconsidered nuclear energy as part of their climate strategies. Rising energy security concerns and the need for reliable low carbon electricity have encouraged many countries to extend the life of existing reactors and invest in next generation nuclear technologies.

India's renewed focus reflects this broader global shift.

India's Ambitious Nuclear Vision

India currently operates a relatively modest nuclear power programme compared to its future ambitions.

With an installed nuclear capacity of approximately 7.5 GW, nuclear energy contributes only a small percentage of India's total electricity generation. In contrast, the national objective of reaching 100 GW by 2047 represents one of the most ambitious nuclear expansion plans in the world.

Achieving this target would require multiple developments taking place simultaneously.

New nuclear power plants would need to be constructed at a much faster pace.

Investment from both domestic and international stakeholders would have to increase substantially.

Advanced reactor technologies would need to become commercially viable.

Manufacturing capabilities for critical nuclear components would require significant expansion.

Skilled human resources, regulatory capacity, and nuclear safety infrastructure would also need continuous strengthening.

This transformation cannot happen through technological advancement alone. It requires policy reforms that improve investor confidence while maintaining the highest standards of nuclear safety.

The Biggest Roadblock: The Civil Liability for Nuclear Damage Act, 2010

Despite signing civil nuclear cooperation agreements with several countries after the landmark India United States Civil Nuclear Agreement, India has struggled to attract foreign investment in nuclear power generation.

The primary reason lies in the Civil Liability for Nuclear Damage Act, 2010, commonly referred to as the CLND Act.

The legislation was enacted after extensive parliamentary debate with the objective of ensuring adequate compensation for victims in the event of a nuclear accident.

The Act places primary liability for nuclear accidents on the operator of the nuclear installation. However, unlike many international liability frameworks, the Indian law also provides operators with a legal right of recourse against equipment suppliers under specific conditions.

This provision fundamentally changed the risk assessment for foreign reactor manufacturers.

Global nuclear suppliers argued that the possibility of post accident liability created financial uncertainty that could not be effectively insured.

As a result, several international companies became reluctant to establish nuclear projects in India despite earlier expressions of interest.

The consequence has been evident over the past fifteen years.

Many proposed projects experienced prolonged delays.

Foreign participation remained limited.

Several agreements did not translate into actual construction.

India's nuclear expansion progressed much more slowly than initially anticipated.

Why Foreign Companies View the CLND Act Differently

Understanding the concerns of foreign reactor manufacturers requires examining international nuclear liability principles.

Globally, most nuclear liability frameworks channel legal responsibility primarily toward the plant operator rather than equipment suppliers. This approach simplifies compensation mechanisms while providing suppliers with greater certainty regarding financial risks.

India's framework differs because supplier liability may arise under certain contractual or legal circumstances.

From the perspective of international manufacturers, this creates additional exposure that increases insurance costs and investment risks.

For multinational corporations making investments worth billions of dollars, legal certainty is often as important as technological capability or market potential.

Consequently, several global suppliers have preferred investing in countries where liability frameworks follow internationally accepted conventions with fewer uncertainties.

This has not prevented India from expanding indigenous nuclear capabilities, but it has significantly limited the pace at which foreign technology and investment could contribute to national nuclear capacity.

Balancing Accountability and Investment

The debate surrounding the CLND Act presents a difficult policy dilemma.

Supporters of the existing law argue that strong liability provisions are necessary to protect public interests.

The memories of industrial disasters continue to influence public opinion regarding corporate accountability and compensation.

From this perspective, weakening supplier liability could reduce incentives for maintaining the highest safety standards.

On the other hand, critics argue that excessive legal uncertainty discourages investment without necessarily improving safety.

They contend that modern nuclear reactors already operate under stringent international safety regulations and multiple layers of oversight.

According to this view, attracting advanced reactor technology and global investment is essential if India intends to achieve its ambitious nuclear capacity targets.

The challenge for policymakers is therefore to strike an appropriate balance between ensuring accountability for nuclear accidents and creating an investment environment capable of supporting large scale nuclear expansion.

Finding this balance will likely determine whether India's goal of achieving 100 GW of nuclear capacity by 2047 becomes a realistic national achievement or remains an ambitious aspiration.
