American Electric Power (AEP) and nuclear technology company X-energy announced in March 2026 a joint effort to evaluate the development of a 960-megawatt (MW) small modular reactor (SMR) nuclear power plant at the retired Rockport Generating Station site in Indiana. The project includes financial backing and a proposed long-term power purchase agreement (PPA) from Amazon to support the plant’s construction and operation.
The planned SMR facility aims to repurpose the existing infrastructure of the former coal-fired power plant, replacing retired coal capacity with advanced nuclear technology. According to the companies, the plant would provide reliable, carbon-free electricity to serve regional utility customers as well as Amazon’s expanding energy needs for its data centers and AI workloads Power Magazine.
X-energy’s SMR design employs high-temperature gas-cooled reactor (HTGR) technology, which the company says offers enhanced safety features and operational flexibility compared to conventional nuclear reactors. The 960-MW capacity would represent a significant addition of clean energy in the Midwest, supporting efforts to reduce carbon emissions in a region historically reliant on coal and natural gas.
AEP stated that the project is currently in the evaluation phase, which includes detailed engineering studies, site assessments, and engagement with the U.S. Nuclear Regulatory Commission (NRC) for licensing. The utility emphasized that leveraging the existing site infrastructure and workforce could help streamline development timelines and reduce costs.
Amazon’s role in the project involves providing development funding and entering into a proposed PPA designed to offer financial stability for the SMR plant. This arrangement aims to mitigate cost risks for AEP’s utility customers while enabling Amazon to advance its goal of powering its operations with 100% renewable and carbon-free energy Power Magazine.
The Rockport Generating Station previously operated two coal-fired units, which were retired amid increasing environmental regulations and economic shifts favoring natural gas and renewable energy sources. Repurposing the site for nuclear power could preserve jobs and maintain grid reliability in the region, according to AEP’s statements.
In a company release, AEP described the SMR project as a “critical component” of its strategy to achieve net-zero carbon emissions by 2050. The utility highlighted the potential for advanced nuclear technology to complement renewable resources and meet future electricity demand with low-carbon generation.
X-energy, headquartered in Maryland, specializes in factory-built modular nuclear reactors designed for on-site assembly, which the company says can reduce construction times and costs compared to traditional reactor projects. Their Xe-100 reactor design, the basis for this project, incorporates passive safety systems and modular scalability features Power Magazine.
Amazon has invested in renewable energy projects such as solar and wind farms but this initiative marks one of its first significant engagements with advanced nuclear power. The company’s support for SMRs aligns with its broader sustainability commitments and efforts to secure reliable, low-carbon power for its data centers.
The regulatory process for SMRs remains complex and will require extensive NRC licensing, environmental reviews, and community engagement before construction can proceed. The U.S. Department of Energy and the current federal administration have increased support and funding for advanced nuclear technologies, accelerating interest in projects like this one.
Industry analysts note that the partnership between AEP, X-energy, and Amazon could serve as a model for collaboration between utilities and technology companies in financing and deploying next-generation nuclear plants. The proposed PPA by Amazon may help mitigate traditional financial risks associated with nuclear construction, which has historically faced cost overruns and schedule delays.
If completed, the 960-MW SMR plant would significantly diversify Indiana’s energy portfolio and contribute to emissions reductions in a state that has relied heavily on fossil fuels. It would also position AEP as a leader in the deployment of advanced nuclear technology and provide Amazon with a stable, clean energy source for its cloud and AI infrastructure.
This announcement reflects a broader trend of utilities and technology firms exploring nuclear power as a complement to renewables, particularly for baseload generation and grid reliability. The use of retired coal plant sites for SMRs also aligns with efforts to transition energy infrastructure away from fossil fuels while utilizing existing grid connections and workforce expertise.
In summary, the collaboration between American Electric Power, X-energy, and Amazon to evaluate a 960-MW small modular reactor at a retired Indiana coal plant site represents a significant development in clean energy infrastructure. The partnership aims to deploy advanced nuclear technology to provide reliable, carbon-free power while managing financial risks through Amazon’s involvement Power Magazine.
