How is Amazon Powering AI Growth through Nuclear Innovation?
Amazon is emerging as an influential force in the nuclear energy sector, strategically investing in next-generation technology to meet its ambitious sustainability goals and support the rapid expansion of its data centre infrastructure.
With more than US$500m already committed, the company’s nuclear approach reflects a broader trend: harnessing reliable, carbon-free power to fuel the digital and energy transitions.
Pioneering Small Modular Reactors (SMRs)
Amazon has invested over US$500m to advance small modular reactors (SMRs), which are a technologically advanced type of nuclear reactor designed for flexibility and faster construction.
These SMRs can be strategically located closer to Amazon's data centres and urban areas, ensuring a dedicated supply of low-carbon energy while bolstering local energy resilience.
The capability of SMRs to produce electricity with minimal greenhouse gas emissions presents a sustainable alternative to more polluting diesel generators and coal-fired power plants.
Additionally, SMRs require a lower capital investment with shorter building periods compared to traditional nuclear facilities, facilitating broader adoption.
Preserving existing nuclear infrastructure
Collaborating with Talen Energy, Amazon is also introducing a data centre campus in proximity to the Susquehanna nuclear facility in Pennsylvania.
This collaboration entails a commitment to purchase up to 1,920 MW of carbon-free electricity until 2042, crucial for meeting the power demands of Amazon Web Services (AWS) data centres and enhancing AI infrastructure.
The agreement further explores the potential of introducing SMRs to increase nuclear output within Talen’s operations, potentially supplying renewable energy to the PJM grid.
This move is part of a larger US$20bn investment in Pennsylvania, projected to create 1,250 high-skilled jobs.
This partnership is aligned with the growing electricity needs driven by the expansion of AI technologies, providing Talen Energy with stable revenue through long-term contracts.
“Amazon is proud to help Pennsylvania advance AI innovation through investments in the Commonwealth’s economic and energy future,” says Kevin Miller, Vice President of Global Data Centres at AWS.
He adds: “That’s why we’re making the largest private sector investment in state history – US$20bn – to bring 1,250 high-skilled jobs and economic benefits to the state, while also collaborating with Talen Energy to help power our infrastructure with carbon-free energy.”
Backing next-generation nuclear innovation
Amazon’s Climate Pledge Fund, a US$2bn corporate venture initiative, led a substantial US$500m investment round in X-energy, a company pioneering advanced SMRs and high-assay low-enriched uranium (HALEU) fuel development.
The fund is aimed at accelerating sustainable technology deployment, not only aiding Amazon in its net zero target by 2040 but also assisting other companies in achieving similar goals, a decade ahead of the Paris Agreement's timeline.
X-energy’s efforts in design, licensing and fuel fabrication are expected to provide upwards of 5 GW of nuclear capacity by 2039.
Direct nuclear power for data centres
Amazon plans to directly power its data centres with nuclear-generated electricity, a process already initiated at the Susquehanna site.
This step ensures a stable, emissions-free power supply, which is essential for supporting the company's burgeoning demands in AI and cloud computing services.
“At Amazon, our culture is rooted in innovation and speed,” says Kara Hurst, Amazon’s Chief Sustainability Officer.
She adds: “AI can enable both and we’re using it in ways big and small to make progress. This is just the beginning and I’m excited about all the ways AI can help us reach our goals.”
Enabling new nuclear projects
Amazon is also facilitating new SMR developments.
In Washington, a partnership with Energy Northwest aims to construct four reactors at the Columbia Generating Station, initially providing 320 MW of power.
In Virginia, Amazon is partnering with Dominion Energy to explore an SMR project at North Anna, with an expected output of 300 MW and vendor selection set for 2025.
Creating jobs and stimulating economies
Each of Amazon’s nuclear-linked projects promises substantial economic uplift.
The Washington SMR initiative is predicted to create up to 1,000 construction jobs and over 100 permanent roles.
The Pennsylvania data centre project will generate additional employment opportunities and modernise local infrastructure.
“Our agreement with Amazon is designed to provide us with a long-term, steady source of revenue and greater balance sheet flexibility through contracted revenues,” says Mac McFarland, President and CEO at Talen.
“We remain a first mover in this space and intend to continue to execute on our data centre strategy. Talen is well-positioned to support Amazon’s energy needs as it invests further in the Commonwealth of Pennsylvania.”
Strengthening energy security and AI
Amazon’s involvement in nuclear energy not only propels decarbonisation efforts but also fortifies America’s stance in global technology and energy leadership.
By potentially generating over 5 GW of new nuclear energy, Amazon is laying the groundwork for energy independence, grid stability and the seamless operation of AI-driven systems that require substantial and uninterrupted power supplies.
“We’re proud to be expanding our world-class data centre infrastructure, bringing more renewable energy projects online and supporting the country’s vision to be a global AI leader,” says Matt Garman, CEO of Amazon Web Services (AWS).
