Amazon reportedly weighs 12 small reactors totaling 960MW at a former Indiana coal plant, paying the construction costs itself so they stay off household power bills

Amazon is reportedly considering a plan to build 12 small modular reactors (SMRs), totaling 960MW, at the site of a former coal-fired power plant in Indiana (TechCrunch, October 19). Trade publication Utility Dive reported that utility AEP has signed an agreement with Amazon and X-energy to advance a 960MW nuclear project.

The most important part of this story is not the number of reactors or their output. According to reports, Amazon would bear the full cost of construction and would not pass it on to other customers. The plan uses a contract to answer protests demanding that the cost of electricity used by data centers not be added to household power bills. All of this is based on media reports. At the time of writing, the announcements from Amazon, AEP and X-energy themselves could not be verified.

The plan as reported

The outline that emerges from the reports is as follows.

• Location: the site of a former coal-fired power plant in Indiana.
• Scale: 12 small modular reactors, totaling 960MW.
• Companies involved: Amazon as the customer, AEP as the utility, and X-energy as the reactor developer.
• Cost: Amazon would reportedly bear it, without passing it on to other customers' rates.

Dividing 960MW by 12 gives 80MW per unit. That matches the per-unit output of X-energy's Xe-100 high-temperature gas-cooled reactor. However, this is an inference from simple division; we have not confirmed from reports which reactor would be used.

There is a reason to use a former plant site. A former coal plant site already has grid connection equipment, cooling water, and permits for land that has been used for power generation. Compared with building from scratch on new land, this can ease the wait in the grid interconnection queue and the work of local coordination. Proposals to replace retiring U.S. coal plants with nuclear have been discussed before, but there have been few cases where a large customer was reported to cover the entire cost.

Who pays had become the central issue

Over the past year, the center of local disputes over data centers has shifted from noise and water to electricity bills. When a large data center arrives, the utility adds power plants and transmission lines. That cost is normally shared among all customers, including households, through rates approved by regulators. Even when demand growth is driven by data centers, the burden can fall on residents. That is the main argument of the opposition.

Among the issues Nohumans has been following, disputes over data center siting continue in Memphis, Loudoun County in Virginia, Charlotte, Project Jupiter and elsewhere. Everywhere, the question "Who pays?" now comes up before permit reviews and legislative debate.

If the reports are accurate, Amazon's plan answers this question in advance. The party that uses the plant pays to build it, and the cost is excluded from the rate calculations for other customers. It responds to the objection that power bills will rise not with promises of technology or jobs, but with how the cost is carried.

Why Amazon would pay itself

On the surface, it is a gesture toward the local community, but it may also make sense for Amazon. There are three reasons.

First, speed. For a utility to recover costs through rates, it needs a rate proceeding reviewed by the state's public utility regulator. If other customer groups or consumer advocates object, the review drags on. By covering the cost itself, Amazon removes the strongest argument against the project, the burden on households, which could shorten the path to approval.

Second, securing power. In the scramble for AI computing resources, there is a growing view that the scarce resource is power rather than chips. With a plant it funded itself, it is easier to arrange priority use of the output.

Third, reputation. If local opposition halts construction, that costs more. Being able to say it will cover the power costs itself becomes a bargaining chip in future siting negotiations.

What is still unknown

Because this is based on media reports, much remains unclear.

• Total cost: how much it would cost to build 12 units totaling 960MW does not appear in what has been reported. Because few small reactors have actually been built, construction cost estimates vary widely, and we will not guess at a figure here.
• Regulators: an arrangement that keeps costs off other customers takes effect only once Indiana's public utility regulator approves it. There are no reports that it has been approved.
• Nuclear licensing: construction and operating licenses from the U.S. Nuclear Regulatory Commission (NRC) are required. How far that process has progressed is unknown.
• Timing: when construction would begin and when operations would start. Small reactors are often expected to start operating in the 2030s at the earliest.
• Cost overruns: if construction costs far exceed estimates, would Amazon also cover the excess? Whether the promise not to pass costs on to households actually holds depends on this condition.

The last point carries particular weight. Large U.S. nuclear projects have seen cases where costs that ran far over budget were passed on to rates and became a problem. How far "not passed on to households" extends cannot be judged without seeing the details of the contract.

What this plan means

The debate over data center power has shifted from how much power is needed to who bears its cost. If the reports are accurate, Amazon's plan becomes one example of answering the latter through a contract.

If this model spreads, large customers may offer a trade in many places: they cover the costs themselves in exchange for faster approval. Conversely, if regulators reject the arrangement, or if construction costs balloon and the promise wavers, opponents will strengthen their argument that "it ends up on household bills after all."

What is certain now is only the direction indicated in the reports: Amazon would carry the cost, and it would not be passed on to other customers. The next thing to check is whether regulatory filings or company announcements emerge to back that up.
