- Amazon has signed an agreement with X-energy and American Electric Power (AEP) to back a 960-megawatt nuclear energy facility in Indiana.
- The installation will feature 12 Xe-100 small modular reactors (SMRs) built on the site of a retired coal plant in Sullivan County.
- Amazon will serve as the primary power customer and investor, with project completion targeted no earlier than the mid-2030s.
Revitalizing Former Coal Infrastructure
Cloud and retail giant Amazon has deepened its push into advanced nuclear power by partnering with reactor designer X-energy and utility provider American Electric Power (AEP). The multi-party agreement outlines the deployment of a clean-energy generation site at the decommissioned coal-fueled Breed Generating Station located in Fairbanks, Sullivan County, Indiana.
Under the project framework, the site will house an array of 12 advanced Xe-100 small modular reactors. Capable of delivering up to 960 megawatts (nearly 1 gigawatt) of electricity to the grid, the power output will support local infrastructure as well as Amazon’s energy-intensive regional datacenters.

| Expected Completion | Mid-2030s at the earliest |
Regulatory Hurdles and Technology Maturity
The Xe-100 design engineered by X-energy relies on high-temperature, helium-cooled architecture powered by uranium fuel sealed within micro-encapsulated TRISO pebbles. Amazon confirmed it is funding the project with an undisclosed financial contribution, framing its commitment around de-risking early-stage infrastructure and serving as the anchor buyer.
However, bringing the installation online hinges on extensive Nuclear Regulatory Commission (NRC) processes. The United States does not currently operate any commercial power-generating SMRs. Unlike standard design certifications that cover generic deployments, the Indiana installation will require site-specific construction permitting. While X-energy is in late-stage reviews for a four-reactor industrial site in Texas, licensing a 12-reactor complex in Indiana represents an independent regulatory journey. According to company sources, completion is anticipated “as early as the mid-2030s,” a timeline that remains subject to shifting development milestones.
Big Tech’s accelerating need for firm, baseload power to feed server infrastructure is shifting capital directly into novel reactor development. While these multi-party agreements secure long-term energy pipelines, commercial execution depends heavily on navigating strict regulatory hurdles that span the next decade.
A mid-2030s target feels overly optimistic given the NRC’s track record with novel designs. Deploying twelve unproven commercial reactors simultaneously carries massive capital risks and potential supply chain bottlenecks. Securing the TRISO fuel supply alone at that scale could easily derail these cost and timeline estimates.
