India Bets on Nuclear Power to Fuel AI Data Centers

India is turning to nuclear energy to meet the surging power demand from AI-driven data centers, with a new Nuclear Energy Mission targeting 100 GW capacity by 2047. This move aims to ensure energy security, reduce fossil fuel dependence, and sustain hyperscale growth.

Why Nuclear Energy for Data Centers?

• AI workloads: A single AI server rack consumes 5–6 times more power than a conventional rack.
• Data center growth: India hosts <5% of global data centers despite accounting for 20% of global data consumption.
• Energy demand forecast: Capacity is expected to rise from <2 GW in 2025 to 8–15 GW by 2030.
• Policy push: The Nuclear Energy Mission aligns with India’s net-zero 2070 target and aims for 100 GW nuclear power by 2047.

Key Players Driving the Shift

• Reliance Industries: ₹1.6 lakh crore investment in a 1.5 GW AI cluster in Visakhapatnam.
• Google: $15B investment in a 1 GW hyperscale hub.
• Adani Group: $100B pan-India AI-ready infrastructure plan.
• Tata Group: Expanding with global partners like AWS and OpenAI.

Comparison: Energy Options for Data Centers

Energy Source	Reliability	Scalability	Carbon Impact	Suitability for AI
Nuclear	High	Very High	Low	Strong (stable baseload)
Solar	Medium (daylight dependent)	High	Very Low	Limited (needs storage)
Wind	Medium (seasonal)	Medium	Very Low	Moderate
Coal	High	High	Very High	Strong but unsustainable

Strategic Implications

• Energy Security: Nuclear reduces reliance on imported fossil fuels.
• Geopolitical Stability: Provides a resilient backbone for AI infrastructure amid global supply chain risks.
• Sustainability: Complements solar and wind to meet net-zero 2070 goals.
• Global Positioning: Positions India as a potential AI infrastructure hub, competing with Singapore, UAE, and US.

Small Modular Reactors (SMRs)

In late 2022, Union minister Dr Jitendra Singh has unveiled that India is taking steps for development of Small Modular Reactors (SMR), with up to 300 MW capacity to fulfill its commitment to Clean Energy transition.

SMRs are increasingly seen as a strategic solution to power India’s fast‑growing data center sector, offering clean, reliable baseload electricity that can sustain AI workloads and hyperscale operations. Experts highlight their role in ensuring energy security, resilience, and uninterrupted supply for mission‑critical infrastructure.

SMRs can directly power hyperscale clusters in Visakhapatnam, Hyderabad, and Mumbai. Unlike solar or wind, SMRs provide continuous electricity, crucial for AI clusters that cannot tolerate downtime.

Risks & Challenges of Nuclear Power in Data Centre 

• Execution risk: Scaling nuclear capacity from current levels to 100 GW by 2047 is ambitious.
• Cooling & water demand: AI data centers could drive water usage to 1,068 billion liters annually by 2028.
• Regulatory hurdles: Streamlined approvals across states are critical.
• Public perception: Nuclear projects often face opposition due to safety concerns.
