Amazon Backs 12 Small Nuclear Reactors at an Indiana Coal Site

Amazon, X-energy, and American Electric Power have announced a plan to build up to 12 small modular nuclear reactors on the site of a former coal plant in Indiana, with Amazon as the first customer for the electricity. The project would add up to 960 megawatts, and Amazon says the power would serve both the regional grid and its own data centers, making it one of the clearest examples yet of AI-driven electricity demand reshaping the energy mix.

The announcement, made on October 19, 2026, is also a reminder of how much has to go right. The reactor design is not yet operating commercially, and the two companies' own descriptions differ on how firm the commitment is.

What was announced

According to Amazon's announcement, the project would use 12 of X-energy's Xe-100 reactors, each rated at 80 megawatts, for up to 960 megawatts of carbon-free power. The Xe-100 is a high-temperature, gas-cooled design that uses helium coolant and TRISO fuel, and Amazon says it can be configured with air-cooled, water-cooled, or hybrid cooling depending on site conditions. The site is the former Breed Generating Station, a coal-fired plant in Sullivan County, Indiana, and AEP's Indiana Michigan Power subsidiary would be the utility partner. Amazon describes itself as a project development funder and the first buyer of the plant's output.

TechCrunch reported the same capacity and equipment, describing the location as a demolished coal plant just south of Terre Haute and saying AEP would operate the plant. It notes the deal is Amazon's second with X-energy and about three times the size of the first, announced in October 2024, when Amazon led a $700 million funding round in the company. Together, the partners are targeting 5 gigawatts of new U.S. nuclear capacity by 2039.

How firm is the commitment?

The two accounts use different language. TechCrunch says Amazon is funding development of a proposed plant. Amazon's page says the three companies have signed an agreement to explore deploying the technology, and it does not describe a construction start, operating date, or permit status. Neither source gives a cost or a timeline for the Indiana plant. Readers should treat the project as an early-stage development agreement, not a construction commitment.

Amazon also lists local benefits it expects: more than 1,000 construction jobs and more than 100 permanent jobs. These are the company's projections. It adds that it will cover the full electricity costs of its data centers under the White House Ratepayer Protection Pledge, and that AEP plans to cut residential rates by $100 starting in 2027 and freeze them for three years. The pledge and the rate plan are Amazon's description; neither is independently confirmed in the sources reviewed here.

Why AI demand is driving the deal

The environmental case for such projects rests on a simple trade. Data centers running AI workloads need large amounts of steady power, and developers want that power to be low in carbon. Nuclear plants run around the clock, unlike wind and solar, and sited on a former coal plant, they can reuse existing grid connections. Amazon frames the project as new carbon-free supply for Indiana.

It is worth separating the climate benefit from the corporate benefit. Adding carbon-free generation is positive for emissions, but the electricity is partly earmarked for the company that is paying for it, and the plant would also connect to the public grid. How much of the output ends up serving Amazon's data centers versus other customers is not specified in the sources opened. The presence of an AI-driven demand story does not by itself show that total emissions fall; that depends on what the new supply displaces and how fast demand grows.

The execution risk

TechCrunch's reporting highlights several hazards. The Indiana timeline depends on X-energy delivering its first plant at Dow Chemical's Seadrift site in Texas, which will host four Xe-100 reactors. X-energy has not broken ground there, and its construction permit is in the final phases of review by the Nuclear Regulatory Commission. Texas has sued Dow over the Seadrift site, alleging habitual non-compliance with water and solid-waste rules and permits, according to the article. TechCrunch also notes that recent U.S. nuclear plants suffered major budget overruns and schedule slips, and that experts say mass manufacturing of reactors often takes around a decade to pay off.

Markets appear to share some of the caution. TechCrunch reports that X-energy listed on Nasdaq in April 2026 at $23 a share, rose 27% on its first day, and has since fallen by nearly two-thirds. News of the Indiana deal lifted the shares about 10% in premarket trading, but they were down less than 2% by the time of publication.

What to watch next

Several milestones will show whether the project is real. The first is the regulatory approval for Seadrift, because both the Texas plant and the first-of-a-kind learning it provides sit upstream of Indiana. The second is a definitive agreement that moves from exploring deployment to a development schedule with cost estimates and permitting steps. The third is the grid context: how Indiana regulators, ratepayers and AEP treat a large new customer, and whether the promised protections for households hold up in practice.

There is also a broader environmental question about how AI companies account for the energy they use. Pairing new data centers with firm, low-carbon supply is a more direct answer than purchasing offsets, but the partners' wider nuclear target runs to 2039, while data center demand is rising now. In the meantime, power for that demand will come from whatever is already on the grid. Observers will want to see whether companies publish location-specific emissions data that shows the real effect.

For now, the Indiana plan is best read as a signal of intent from three companies with strong incentives to deliver, resting on a reactor technology that still has to prove it can be built on time and on budget.
