Amazon Web Services (AWS) has embarked on a transformative energy partnership with Talen Energy, securing a 20-year power purchase agreement to draw 1,920 megawatts of carbon-free electricity from the Susquehanna nuclear plant in Pennsylvania. This landmark deal, extending until 2042 with options for extension, marks a significant inflection point in the clean energy strategy of one of the world’s biggest tech companies, driven by the surging electricity demands of AI and cloud computing.
The agreement envisions a phased ramp-up, beginning with delivery between 840 and 1,200 megawatts by 2029, and reaching full capacity by 2032. It operates under a “front-of-the-meter” model, routing power through the PJM grid after planned transmission upgrades scheduled around spring 2026. This approach aims to address regulatory concerns and spread infrastructure investment costs, offering a more balanced grid operation. The deal signifies a strategic pivot for Amazon, which has already invested heavily in renewable energy but now acknowledges nuclear energy’s unmatched reliability and controllability as essential to meeting its future growth.
Kevin Miller, AWS’s Vice-President for Global Data Centers, heralded the deal as the largest private-sector investment in Pennsylvania’s history, involving $20 billion and generating about 1,250 high-skilled jobs. Pennsylvania Governor Josh Shapiro echoed this sentiment, calling it “the largest economic development project in Commonwealth history.” The agreement strengthens Pennsylvania’s standing as a net energy exporter and promises significant fresh investments in grid infrastructure. Indeed, Christine Martin of PPL Electric Utilities highlighted how upfront investments reduce transmission costs, fostering overall grid resilience.
Talen Energy’s CEO, Mac McFarland, emphasised the pact’s value in providing a steady, long-term revenue source that mitigates market risks and reduces reliance on federal tax credits—a noteworthy consideration given the volatile energy markets. Following the announcement, Talen’s share price surged between 4.7% and nearly 8%, underscoring investor confidence. This upbeat market reception extended to nuclear-related equities more broadly, reflecting a renewed appetite for nuclear power fueled by Big Tech’s demand for stable, low-carbon energy.
The focus on nuclear power aligns with broader industry trends. Big tech players such as Microsoft and Google have similarly inked major power deals, reactivating idled reactors and investing in new nuclear projects, including small modular reactors (SMRs). AWS itself is exploring uprating Susquehanna’s output and collaborating on SMR development at the site, illustrating a long-term vision for scalable, advanced nuclear technology. The Department of Energy estimates that U.S. nuclear capacity could triple by 2050, supported by growing government and private sector commitments.
Susquehanna’s dual-unit boiling-water reactor is particularly suited for Amazon’s data centre needs, boasting a high capacity factor and a substantial electricity output—approximately 19,943 GWh in 2021. The power plant is licensed into the 2040s, ensuring a stable supply horizon well suited for AWS’s long-term infrastructure planning.
However, this partnership is not without challenges. The Federal Energy Regulatory Commission (FERC) recently blocked an initial interconnection plan involving AWS and Susquehanna, reflecting regulatory complexities around direct power transactions that bypass traditional electric grid distribution norms. Critics express concern about the fairness of such arrangements and potential implications for grid maintenance costs and energy price dynamics. Regulatory clarity will be vital as this model evolves, especially given growing tensions about equitable energy distribution amid rapid data centre expansion.
The AWS-Talen alliance fits into a larger strategic context where tech companies are rapidly scaling energy needs due to AI workloads. While AWS achieved its 100% renewable electricity goal last year, the exponential growth of generative AI demands additional reliable, carbon-free energy sources. Nuclear power, with its steady baseload generation and price stability, complements intermittent renewables such as wind and solar, providing a strategic hedge against supply volatility.
Amazon is also investing heavily in state and local economic development, with a $20 billion investment in Pennsylvania that includes two major data centre complexes—one co-located next to Susquehanna and another in Fairless Hills. This expansion is part of a broader strategy that sees tech giants repurposing legacy industrial sites and securing direct energy supplies to future-proof their sprawling AI and cloud infrastructures.
In sum, the AWS and Talen Energy agreement signals nuclear energy’s revival as a core pillar of the clean energy transition, particularly in powering data centres, a sector facing rapidly escalating electricity demands. Through combined investments in existing reactors, uprates, and SMRs, alongside supportive policies and infrastructure upgrades, nuclear power is emerging as an indispensable element in the future energy mix for the digital economy. While regulatory hurdles remain, this deal underscores a significant shift in how large tech firms approach clean energy sourcing, balancing innovation with long-term stability and economic impact.
