Can India’s Current Energy Infrastructure Handle AI Data Centres?
The global electricity demand from data centres is projected to rise from approximately 460 TWh in 2024 to over 1,300 TWh by 2035. Within this energy-intensive landscape, artificial intelligence (AI) has emerged as the primary driver of surging power consumption, with GPU-driven workloads requiring 80-150 KW per rack compared to traditional servers consuming just 15-20 KW. India is at a critical juncture: its AI ambitions, bolstered by the Digital India initiative and 5G rollout, are quickly outpacing its current energy solutions.
The Ministry of Atomic Energy’s contemplation of Small Modular Reactors (SMRs) as a sustainable solution signals the urgency of addressing AI data centres’ growing energy appetite. With AI-based operations now a pillar of the global tech economy, SMRs could bridge the gap between supply and demand. However, this reliance on nuclear infrastructure raises questions about feasibility and timelines in a country where even conventional reactor deployment faces significant delays.
The Promise of Small Modular Reactors
Unlike traditional nuclear power plants, SMRs are compact, factory-assembled reactors with a generation capacity of up to 300 MW(e). This modularity allows flexibility not available with larger reactors, enabling incremental capacity additions tailored to data centre clusters. Globally, their successful implementation is evident in Russia’s Akademik Lomonosov (a floating nuclear power unit) and China’s HTR-PM demonstration project, which achieved commercial scale in 2023.
India’s investment plans reflect strategic ambition—a Rs 20,000 crore R&D mission announced to develop indigenous SMR technology, aiming for deployment of at least five reactors by 2033. The Bhabha Atomic Research Centre’s (BARC) Bharat Small Reactor (BSR) project exemplifies these efforts, with a focus on incorporating advanced safety measures while re-engineering existing reactor designs.
International collaboration is another cornerstone. Recent agreements with France could provide expertise on advanced modular reactor technology that aligns with India’s domestic needs. Yet, even with such initiatives underway, deployment within the proposed timeframe will require overcoming daunting institutional and regulatory barriers.
What the Data Obscures
The narrative around SMRs and their applicability to India’s energy dilemma, though optimistic, faces critical gaps. For instance, India’s nuclear liability law—the Civil Liability for Nuclear Damage Act, 2010—channels operator liability to equipment suppliers, discouraging foreign investment due to financial risks. Without amendments, India risks alienating essential international partners, a concern amplified by the complexity of SMR supply chains that rely heavily on cross-border expertise.
Furthermore, SMRs, while compact and less capital-intensive than traditional reactors, require substantial upfront investment ranging between $2,000-$4,000 per kilowatt. This high initial cost could delay deployment, especially for a country already grappling with financing renewable energy projects. Critical questions about nuclear waste disposal also remain unanswered. SMRs will not solve the deep-seated issue of nuclear waste management unless India invests parallel energy in improving disposal facilities and monitoring mechanisms.
Perhaps the most ironic tension lies in regulatory readiness. India’s nuclear oversight remains tailored to large reactors, with no streamlined framework for licensing modular designs. Globally, countries like the United States have already adopted technology-neutral frameworks under agencies like the Nuclear Regulatory Commission. India, by contrast, appears locked in regulatory inertia, with the Atomic Energy Regulatory Board (AERB) yet to meaningfully adapt its policies to modular reactor technology.
Why Intermittency Matters
The push for SMRs must also be understood in the context of renewables. Solar and wind, despite their green credentials, remain inefficient in addressing the stable power demand of AI-driven workloads. Intermittency and inadequate battery storage remain key challenges. Data centres require round-the-clock, predictable power supply—a necessity poorly aligned with fluctuations inherent in renewable energy sources.
However, the shift towards nuclear power risks sidelining investments in storage technologies that could make renewables viable for these high-demand applications in the longer run. The 15th Finance Commission had earmarked significant funds for green energy corridors; repurposing these allocations toward SMRs may seem politically expedient but could undermine balanced sectoral development.
Lessons From France: A Concrete Comparison
France presents a useful contrast—its nuclear ecosystem contributes a substantial share (nearly 70%) of its electricity generation. The country provides streamlined licensing under the European Utility Requirements framework and encourages modular innovation while maintaining rigorous safety standards. This proactive regulatory regime has enabled the accelerated deployment of pilot SMRs such as Nuward. Given India’s intention to collaborate with France on advanced modular reactors, emulating such frameworks could fast-track domestic projects.
At the same time, France’s model highlights a caveat India cannot afford to overlook: the risks of over-relying on nuclear energy as a primary source. Despite high nuclear penetration, France experienced acute power shortages in 2022 due to reactor inefficiencies, underscoring the importance of diversification—a lesson India must heed while pursuing SMR deployment for energy-intensive AI operations.
Looking Ahead: Can India Deliver?
To ensure SMRs deliver on their promises, India must prioritize robust legislative reforms, including amendments to liability laws, and invest heavily in nuclear waste management R&D. Building a capable domestic supply chain for SMRs' prefabricated components should be another strategic focus. Collaborations with countries like France need to transcend agreements and translate into tangible manufacturing and deployment expertise.
As ground realities evolve, much depends on whether SMRs can achieve operational cost parity with conventional reactors and renewable alternatives. Success metrics will include both deployment speed and whether these reactors can sustainably meet AI workloads without escalating operating costs. However, India’s long-standing delays in nuclear project execution, paired with regulatory bottlenecks, suggest cautious optimism rather than outright confidence.
