The data center industry's growing demand for sustainable and reliable energy sources has led to increased interest in nuclear power, especially small modular reactors (SMRs), as a viable solution for powering data centers. In this week's blog, Platocom examines the partnerships between tech companies and nuclear energy providers.
Think of a data center as a giant storage space for everything you do online. Whenever you send an email, post a photo on social media, or check your bank statement, that information is stored in a data center.
AI and Crypto Currency Are Energy Thieves
As data centers continue to grow in size and importance, their hunger for electricity is surging, fueled by trends like AI applications and cryptocurrency mining. This puts immense pressure on the global energy grid, driving data center operators to explore more reliable and sustainable energy sources. One solution gaining momentum is nuclear energy—a carbon-free alternative to fossil fuels with the potential to provide the consistent, large-scale power these facilities need.
A Precise Balance Between Renewable/Clean & Nuclear Energy
Addressing surging global energy demand while preserving a sustainable future will require a precise balance between renewable and nuclear energy. Both energy sources play crucial roles in the transition to a low-carbon economy and a livable planet. Renewable energy sources, such as wind and solar, are essential for reducing greenhouse gas emissions, but their intermittent nature necessitates reliable backup power to ensure a stable energy supply. Nuclear energy, with its ability to provide firm, continuous power, complements renewables by filling in the gaps when solar and wind generation is low.
In a previous blog, team Platocom explored Bill Gates' nuclear energy ventures, specifically TerraPower's efforts in Wyoming to develop advanced reactors. TerraPower's Natrium reactor and energy storage system redefines what nuclear technology can be: emissions-free, competitive, and flexible. Built for the 21st-century grid, TerraPower's Natrium technology is one of the fastest and lowest-cost paths to advanced, zero-carbon energy.

Current Landscape of Tech-Nuclear Partnerships
Tech companies like Microsoft and Amazon Web Services (AWS) are leading the way in global energy consumption. With the rise of data centers, AI applications, and cryptocurrency, these companies face increasing pressure to source their electricity from carbon-free options. For example, Microsoft’s recent power purchase agreement (PPA) with Constellation to restart an 835-megawatt nuclear plant in Pennsylvania exemplifies this trend. This agreement is significant as it marks the second instance this year where a nuclear power plant has committed to supplying dedicated power to a data center, highlighting the growing interest in nuclear energy as a reliable electricity source.In March, AWS signed a contract for 960 megawatts of capacity from Talen Energy’s Susquehanna nuclear power plant.
Innovating for Energy Equity and Global Impact
The agreements between tech companies and nuclear energy providers have the potential to reshape energy systems worldwide. These projects often extend beyond individual facilities, reaching communities that have historically been overlooked in renewable energy development. Microsoft’s collaborations with renewable energy partners not only increase capacity but also deliver direct benefits to local communities.

Key Partnerships and Initiatives
Google and Kairos Power: Google has entered into a partnership with Kairos Power to develop up to seven small modular reactors (SMRs) that will provide up to 500 MW of power. This initiative is part of Google's strategy to achieve net-zero and 24/7 carbon-free energy goals, with the first unit expected to come online by 2030 and the entire project completed by 2035. Read Platocom's blog about Google and Kairos Power here.
Amazon and X-energy: Amazon has invested approximately $500 million in X-energy to support the deployment of over 5 gigawatts (GW) of new power projects across the United States by 2039. This includes the initial deployment of four X-energy Xe-100 reactors, designed to scale up to 12 units and 960 MW of power.
AWS and Talen Energy: AWS is acquiring a hyperscale data center in Pennsylvania, which will be directly powered by the nearby Susquehanna nuclear power plant. This facility will have a capacity of 960 MW and is part of AWS's broader effort to achieve net-zero carbon emissions by 2040 - more info here.
Microsoft and Constellation Energy: Microsoft has partnered with Constellation Energy to restart the Unit 1 reactor at the Three Mile Island nuclear power plant in Pennsylvania. This reactor will provide power to Microsoft's data centers in the mid-Atlantic region and is expected to be operational by 2028 - more info here.
Duke Energy Collaborations: Duke Energy has teamed up with Amazon, Google, and Microsoft to accelerate clean energy deployments, including nuclear, in the Carolinas. This collaboration underscores the tech giants' commitment to integrating nuclear power into their energy mix.
These partnerships demonstrate a clear trend of major tech companies actively pursuing nuclear energy solutions to power their data centers, with a particular focus on SMRs and existing nuclear infrastructure.In this post, we’ll take a closer look at how tech companies are partnering with nuclear providers and what this means for the future of data-driven industries.
A Pivotal Moment in the Clean Energy Transition
The partnerships between tech giants and nuclear energy providers represent a pivotal moment in the clean energy transition. Nuclear energy is increasingly recognized as a clean source of power because it generates electricity without emitting greenhouse gases during operation. The restart of Microsoft’s Pennsylvania facility, which was retired in 2019, will provide reliable, carbon-free electricity to the PJM grid, emphasizing nuclear energy's critical role in decarbonizing large power systems.
This aligns with Bill Gates' advocacy for advanced nuclear energy, which stresses the importance of scalable, zero-emission solutions. You can read more about Gates' views on this in his article “How to Avoid a Climate Disaster”.
A Multi-Technology Approach to Grid Decarbonization
Achieving a sustainable energy future requires a multi-technology approach. The International Energy Agency (IEA) has highlighted the necessity for diverse energy sources, including wind, solar, geothermal, clean hydrogen, and nuclear, to meet growing global energy demands while reducing carbon emissions. For insights on this topic, refer to the IEA’s World Energy Outlook.
Microsoft’s decision to complement its extensive renewable energy portfolio with nuclear power exemplifies this strategy. Nuclear energy provides "firm power," a consistent and reliable energy source that is essential for balancing the variability of renewables like wind and solar.
Policy Advocacy and the Future of Carbon-Free Energy
While the restart of nuclear facilities is a significant step forward, public policy remains crucial in making carbon-free energy widely accessible. Effective policies will be essential for scaling innovations like nuclear energy and clean hydrogen, ensuring their safe deployment at scale. Microsoft’s recent policy brief on advanced nuclear and fusion energy highlights the importance of these discussions in creating a pathway for a fully decarbonized grid. You can find more details in their Energy Policy Brief.
Conclusion
As the world accelerates its transition to carbon-free energy, partnerships like the one between Microsoft and Constellation illustrate the power of industry to drive meaningful change. Large-scale energy consumers have the potential to shape demand for cleaner technologies while pushing the boundaries of what's possible in decarbonization. The journey toward a sustainable future is well underway, and the collaboration between tech giants and nuclear energy providers is a promising step in the right direction.
The speed and scale of this transition will depend on innovation, collaboration, and policy reform—factors that are critical to achieving a decarbonized world. As we continue to monitor these developments, we look forward to sharing more milestones on this path to a sustainable energy future.
