Some big tech companies including Google signed agreements to purchase nuclear energy to meet rising electricity demands for Artificial Intelligence data centres.
Which Big Tech Companies Investing in Nuclear Energy
- Google: Google has entered into a corporate agreement to purchase nuclear energy from multiple Small Modular Reactors (SMRs) being developed by Kairos Power.It will provide 500 MW of carbon-free power for development of AI technologies.
- Microsoft: Microsoft signed a 20-year power purchase agreement with Constellation Energy to restart the Three Mile Island nuclear power plant in the US.It will provide approximately 835 MW of carbon-free energy, supporting Microsoft’s goal of becoming carbon negative.
- Amazon: Amazon has formed three agreements to support nuclear energy. It includes, partnership with Energy Northwest for SMRs in Washington, investing in SMR development with X-energy, and collaborating with Dominion Energy in Virginia.
- OpenAI: OpenAI CEO Sam Altman has backed the nuclear startup Oklo, aiming for operational status by 2027. Altman also invested in Helion, a nuclear fusion company, in 2021.
Why Are Big Tech Companies Shifting to Nuclear Energy
- Increasing Energy Demands from AI: The Electric Power Research Institute (EPRI), a non-profit organisation, highlighted that data centres’ electricity consumption could more than double by 2030. Data centres, which are critical for AI operations, are projected to consume up to 9% of the United States’ electricity by 2030, more than double their current usage.
- Limitations of Renewable Energy: Nuclear energy provides continuous and carbon-free power around the clock as AI companies scale their operations.
- Renewable energy sources such as wind and solar are intermittent in nature.
- Sustainability: Major tech companies are increasingly focused on reducing their carbon footprints and achieving sustainability goals. E.g., Google reported a 13% rise in global greenhouse gas emissions in 2023, highlighting the challenges of balancing growth with sustainability.
- Strategic Partnerships and Investments: Tech giants are forging strategic partnerships with energy companies to invest in nuclear power projects. E.g., Microsoft partnered with Constellation Energy to revitalise the Three Mile Island nuclear plant in the US for securing long-term carbon-free energy.
- Potential for Economic Advantage: Investing in nuclear power now enables tech firms to secure a reliable energy source, which will be increasingly valuable as energy competition intensifies.
- Climate Change Concern: Concerns about climate change and energy reliability make nuclear power more appealing, prompting tech companies to justify their investments in this sector.
Nuclear Energy Scenario in India
- India aims to triple its nuclear power capacity to 22,480 MW by 2032, with a goal of deriving 25% of its electricity from nuclear sources by 2050.
- REC (Rural Electrification Corporation) plans to allocate Rs 6 trillion to renewable and nuclear projects by 2030.
- NTPC is partnering with NPCIL (Nuclear Power Corporation of India) to form Anushakti Vidhyut Nigam, focusing on building and operating nuclear power plants.
- India plans to establish 10 new reactors and collaborate with private players to explore SMRs and innovate in nuclear technologies.
Key Points about Small Modular Reactors (SMRs)
- About: SMRs are advanced nuclear reactors that are about one-third the size of traditional nuclear reactors.
- Small Size (S): Power capacity of up to 300 MW(e).
- Modular (M): Components are prefabricated and transported to the installation site.
- Nuclear Reactors (R): Use nuclear fission to generate low-carbon electricity.
Advantages
- Smaller Footprint: SMRs can be installed in locations unsuitable for larger reactors.
- Cost and Construction Efficiency: Prefabrication and modular design reduce construction time and costs.
- Off-Grid Potential: SMRs, especially microreactors (up to 10 MW), can provide power in remote areas.
- Reduced Refuelling Frequency: SMRs may only need refuelling every 3 to 7 years, with some designs lasting up to 30 years without refuelling.
