The U.S. Department of Energy (DOE) has awarded a contract to Amentum to develop a 1-gigawatt (GW) artificial intelligence (AI) data center at the Savannah River site in South Carolina. The project will feature a novel hybrid power system combining natural gas turbines with nuclear energy generation to meet the escalating energy demands of AI infrastructure while aiming to reduce carbon emissions. This initiative represents one of the first large-scale integrations of advanced nuclear power in AI data center operations, according to DOE announcements and industry reports.DOE selects Amentum for 1GW AI data center with gas-to-nuclear power at Savannah River site – Pluang.
The contract was announced in early March 2026, with Amentum, a government services firm specializing in energy and nuclear operations, selected to lead the development. The Savannah River site, historically a nuclear materials processing complex, offers existing infrastructure suitable for energy-intensive facilities. The DOE emphasized that the hybrid power system will combine steady nuclear output with flexible natural gas turbines to ensure reliable, continuous power while enhancing grid stability during peak demand or fuel supply fluctuations.
According to the DOE, the data center will provide a total computing power capacity of 1 GW, addressing the rapidly increasing electrical consumption associated with AI training and inference workloads worldwide. Industry analysts have identified AI operations as some of the highest energy consumers in the technology sector, driving demand for sustainable energy solutions. The Savannah River project aims to pioneer the direct integration of nuclear energy into AI infrastructure to meet these challenges.
The DOE’s award to Amentum followed a competitive bidding process prioritizing innovation in energy management and environmental impact mitigation. Amentum’s proposal was selected for its comprehensive gas-to-nuclear hybridization strategy that leverages the Savannah River site’s existing nuclear expertise and assets. While specific budget and timeline details remain undisclosed, sources indicate the project will progress through multiple phases, with initial power generation expected by 2028.DOE selects Amentum for 1GW AI data center with gas-to-nuclear power at Savannah River site – Pluang.
Energy systems analyst Dr. Elaine Chen of the Energy Futures Institute described the hybrid system as a strategic advancement in data center energy design. She stated, “Integrating nuclear power with gas turbines in a hybrid system addresses both the need for massive, reliable power and the imperative to reduce carbon footprints in high-tech industries.” Chen noted that the Savannah River project could serve as a model for balancing economic and environmental objectives in AI data center construction.
The project aligns with ongoing U.S. energy policies emphasizing clean energy innovation and energy security. Although the current administration under President Donald Trump has shifted certain priorities compared to the previous Biden administration, the DOE’s commitment to nuclear power integration indicates continued recognition of nuclear energy’s role in sustainable power generation.
The Savannah River site has a long-standing history as a federal nuclear research and energy location. Established during the Cold War for nuclear materials production, it has since transitioned to environmental management and research activities. Its existing reactors and waste processing infrastructure provide a distinctive foundation for this hybrid power initiative.
In addition to the hybrid power system, the AI data center will include advanced cooling and power distribution technologies designed specifically for AI workloads. The DOE has highlighted energy efficiency and grid compatibility as key design priorities intended to reduce operational costs and environmental impacts while supporting substantial computational demands.
Market responses to the announcement have been cautiously optimistic. Investors in the energy sector view hybrid nuclear projects as an opportunity to diversify power generation portfolios amid volatile fossil fuel markets and regulatory changes. Simultaneously, AI industry stakeholders recognize the urgent need for stable, scalable power sources to support ongoing advances in machine learning and data processing.
Environmental organizations have raised concerns regarding the expansion of nuclear infrastructure, focusing on radioactive waste management and long-term safety. The DOE has responded by underscoring stringent regulatory oversight and recent technological improvements aimed at enhancing nuclear safety and minimizing waste.
The Savannah River project reflects a broader trend of AI data centers pursuing innovative power solutions. Major technology companies such as Google, Microsoft, and Amazon have invested heavily in renewable energy and efficiency improvements; however, integrating nuclear power remains uncommon. This project thus represents a significant development in the energy landscape for AI infrastructure.DOE selects Amentum for 1GW AI data center with gas-to-nuclear power at Savannah River site – Pluang.
The DOE’s contract with Amentum is anticipated to stimulate further research and development in hybrid energy systems tailored for AI infrastructure. As AI workloads continue to grow, demand for reliable and sustainable power sources is expected to increase, encouraging additional projects that combine multiple energy technologies. The Savannah River data center could become a testbed influencing future industry standards and government policy in energy management for AI.
In conclusion, the DOE’s award of the contract to Amentum to build a 1GW AI data center powered by a gas-to-nuclear hybrid system at the Savannah River site marks a significant step toward addressing the intersection of AI infrastructure expansion and sustainable energy. By integrating advanced nuclear technology with flexible natural gas power, the project aims to deliver reliable, lower-carbon energy to support next-generation AI computing demands.
