The demand for datacenters to support generative AI has led major companies like Amazon and Microsoft to seek alternative sources of energy. Nuclear power is emerging as a promising solution due to its ability to provide a large amount of energy in a sustainable and carbon-free manner.
Amazon Web Services (AWS) made headlines earlier this year when it acquired Talen Energy’s Cumulus Data Assets for $650 million. This nuclear-powered data center is located on site at Talen’s Susquehanna nuclear plant in Pennsylvania. In addition to this purchase, AWS has also secured a 10-year Power Purchase Agreement (PPA) that allows them access to nuclear energy from the same site. This move demonstrates AWS’s commitment to integrating nuclear power into their data center operations.
Similarly, Microsoft has been investing in nuclear power for its data centers. In 2020, Microsoft signed a deal with Constellation to receive up to 35% of its power from nuclear sources for its Boydton, VA, data center. This is in addition to the solar and wind purchases that Microsoft already has from Constellation. The company has also entered into a nuclear carbon credits deal with Ontario Power Generation, further emphasizing its dedication to nuclear energy.
These collaborations between technology giants and nuclear power providers reflect the broader industry’s efforts to address the energy demands of large-scale datacenters. Hyperscalars, as these datacenters are known, are exploring various options to secure a reliable and sustainable energy supply. One option is to partner with existing nuclear power providers to access energy or to utilize small module nuclear reactors (SMRs) with smaller carbon footprints.
A number of companies, including Nucor, Oklo, Rolls-Royce SMR, Westinghouse Electric, Moltex Energy, Terrestrial Energy, General Electric, Hitachi Nuclear Energy, and X-energy, are currently developing SMRs to meet the growing needs of AI data centers. However, it is important to note that these SMRs are not expected to be operational until 2030, according to an energy analyst. Despite the timeline, the urgency to find sustainable alternatives to electricity, wind, and solar power is pressing.
The increasing demand for electricity, coupled with the expansion plans of datacenter companies, has pushed industry leaders like Google, Amazon, and Microsoft to seek innovative solutions. On-site nuclear-based SMRs, as well as fusion reactors, are now being explored as potential options. This global arms race for power is unprecedented and highlights the industry’s determination to ensure a reliable and clean energy supply for their data centers.
Incorporating nuclear power into data center operations brings its own set of challenges and considerations. Safety is of paramount importance, and regulatory approvals, such as those required from the Nuclear Regulatory Agency, must be obtained. However, the potential benefits of nuclear power, such as its high energy density and continuous power generation, make it an attractive option for companies seeking to support generative AI without contributing to carbon emissions.
In conclusion, the demand for datacenters to power generative AI applications has led companies like Amazon and Microsoft to explore alternative sources of energy. Nuclear power is emerging as a promising solution, with major players investing in nuclear-powered data centers and securing access to nuclear energy. The development of small module nuclear reactors (SMRs) further indicates the industry’s commitment to sustainable and carbon-free alternatives. While the operationalization of SMRs may still be several years away, the race to secure innovative power solutions for data centers reflects the unique challenges and opportunities facing the technology industry. As AI continues to evolve and demand for computing resources grows, finding sustainable energy solutions will be crucial to support the digital transformation of society.
