Context: AI data centres — the digital engines behind Generative AI and cloud services — are driving massive global power demand, forcing countries to explore low-carbon, 24×7 energy sources like Small Modular Reactors (SMRs).
- India, through its Nuclear Energy Mission (2025), has announced plans to deploy indigenously built SMRs to meet rising AI and data infrastructure energy needs.
India’s Electricity Demand: Data and Trends
- Flat but Rising Curve: India’s electricity demand remained steady at ~5% annual growth for two decades, but is now rising with AI, EVs, and green hydrogen.
- Industrial Shift: Energy-intensive sectors like data centres, 5G, and digital manufacturing are adding new base-load demand layers.
- Capacity Challenge: Despite being the third-largest electricity producer, India’s grid faces localised shortages and transmission stress.
- Decarbonisation Pressure: India targets 500 GW of renewables by 2030, but intermittency remains a hurdle for 24×7 supply to high-load facilities.
Need for AI Data Centres:
- Digital India Push: Policies like data localisation and Digital India require massive domestic storage and processing infrastructure.
- 5G & IoT Explosion: Rollout of 5G and IoT devices generates exponential data, necessitating high-performance computing hubs.
- AI and Cloud Workloads: Generative AI and LLMs require high-density GPUs, transforming data centres into computational power grids.
- Security & Sovereignty: India’s data protection regime demands that sensitive data be processed within national borders.
- Economic Multiplier: The AI data centre ecosystem can generate jobs, attract FDI, and enhance India’s role as a global digital hub.
Global and India Scenario:
- Global Growth: Worldwide electricity use by data centres may rise from 460 TWh (2024) to 1,300 TWh by 2035, led by the U.S. and China.
- S. Leadership: The U.S. holds 51% of global capacity, with hubs in Texas, Virginia, and Phoenix, driving 25% grid demand growth.
- India’s Expansion: India’s current 1.4 GW capacity may reach 7 GW by 2030, with projects by Google, Reliance, AdaniConneX, and Yotta.
- Regional Focus: Key clusters are emerging in Mumbai, Chennai, Bengaluru, Hyderabad, Jamnagar, and Visakhapatnam under the IndiaAI Mission.
Role of Small Modular Reactors (SMRs) in Power Supply:
- Baseload Solution: SMRs provide 24×7 low-carbon baseload power, ideal for continuous AI data centre operations.
- Scalable & Modular: With 1–300 MW range, SMRs can be deployed near consumption hubs, reducing transmission losses.
- Safety by Design: Incorporate passive cooling, smaller cores, and accident-tolerant fuels, enhancing reliability.
- Global Investment: Over $15.4 billion has been committed globally; India plans to commission five SMRs by 2033.
- Policy Backing: India’s ₹20,000 crore Nuclear Energy Mission aims for 100 GW by 2047, with reforms to attract $26 billion private investment.
Limitations and Concerns of SMRs:
- Regulatory Bottlenecks: Current licensing frameworks are tailored to large reactors, delaying SMR approvals.
- Cost Overruns: Despite modularity, initial capital costs remain high without large-scale deployment.
- Waste Disposal Issues: New fuel types (e.g., HALEU) pose challenges for long-term waste management.
- Transportation Risks: Factory-fabricated units require secure logistics and radiation safeguards.
- Public Acceptance: Despite improved safety, social resistance and nuclear liability concerns persist.
Way Ahead:
- Regulatory Reforms: Develop technology-neutral, streamlined licensing aligned with IAEA’s harmonisation frameworks.
- Public-Private Partnerships: Facilitate joint ventures among SMR vendors, AI data centre players, and renewable firms.
- Site Repurposing: Convert retired coal plants and hydrogen hubs into nuclear-ready SMR sites.
- Skilling and Research: Train regulators, re-skill the coal workforce, and promote SMR R&D collaboration with global leaders.
- Integrated Power Strategy: Combine renewables, SMRs, and storage systems to create resilient digital energy ecosystems.
Conclusion:
As AI becomes the new industrial engine, energy will be its oxygen. India’s leap toward Small Modular Reactors and renewable hybrids offers a pathway to power this intelligence responsibly. The future belongs to nations that can balance computation with clean, continuous, and conscience-driven energy.
