American Electric Power announced on 19 October 2026 a joint development agreement with X-energy to evaluate building a 960-megawatt advanced nuclear plant at a former coal plant site in Sullivan County, Indiana, with Amazon supporting the project’s development through a funding agreement. If the project goes ahead, Amazon intends to buy the power under a long-term contract, “covering the costs of the facility and its operations for the duration of the contract,” AEP said. Bloomberg also reported the plan on 19 October.
The plant would use 12 of X-energy’s Xe-100 small modular reactors of 80 MW each. The companies expect to decide whether to proceed by late 2029, Bloomberg reports. Terms weren’t disclosed, according to Bloomberg.

A short explainer on power purchase agreements. It teaches the general idea only and says nothing about any company in this story.
The key insight: As we read it, Amazon is taking the cost risk of a reactor plan that has not yet been approved: AEP says Amazon funds the development work and intends to buy the power under a contract covering the facility’s costs, while the Xe-100 design still requires federal approval, Bloomberg reports.
AEP says the agreement with X-energy is to evaluate the feasibility of the project, and that the completed facility would add electricity to the grid only if the development project reaches a final investment decision and moves on to construction and commercial operation. The initial project would include 12 Xe-100 units configured in groups of four, for a total of 960 MW, AEP says.
The companies are evaluating the former site of Indiana Michigan Power’s Breed Generating Station in Sullivan County as the location, according to AEP. Sullivan County recently became part of the Indiana Advanced Nuclear Ready Communities Program, the utility says.
“Our agreements with Amazon and X-energy will provide all necessary capital protections and financial safeguards that we have said are essential for any potential nuclear project to move forward,” said Bill Fehrman, AEP’s chairman, president and chief executive.
AEP’s three large power agreements of 13 to 19 October 2026, by capacity: the 960 MW X-energy planAmazon is funding (AEP and Amazon, 19 October), the 702 MW Bloom fuel-cell project for Google (AEP, 14 October) and up to 1.6 GW of Mainspring linear generators (Mainspring, 13 October). The 3,262 MW total and its share of the 63 GW Bloomberg says AEP must add by 2030 are our arithmetic; not all of it would be online by 2030.
Bloomberg’s post on the plan, published at 12:30 UTC on 19 October. Its report adds the late-2029 decision date, AEP’s 63 GW need by 2030 and the note that the Xe-100 design still requires federal approval, all cited in this piece.
โ10 years from now, nuclear will be boring, abundant, and easy to buy.โ
That’s the goal, says X-energy CEO J. Clay Sell: make nuclear power predictable, repeatable, and commercially competitive.
X-energy’s own account on 16 October, three days before the Indiana announcement, quoting chief executive J. Clay Sell on the company’s goal for nuclear power. It is the company’s stated aim, not a statement about this project.
Who Pays
Amazon describes itself as a project development funder that would be the first customer to buy power from the plant once it operates. “Together, we’re looking to develop nearly a gigawatt of carbon-free power for the regional grid and pay our full costs without passing them to others,” said Josh Weissman, vice president of data center infrastructure capacity delivery at Amazon, in AEP’s release.
Amazon says the plant would serve both the regional power grid and its data centers. It calls this the second project in its collaboration with X-energy, which aims to add more than 5 gigawatts of new nuclear capacity to the US grid by 2039, after the Cascade Advanced Energy Facility in Washington state.
Amazon led X-energy’s Series C-1 financing round in 2024, which closed at $700 million, the company says. For comparison, AEP said on 14 October that it plans to invest about $4 billion in a Wyoming fuel-cell project under a 20-year power purchase agreement with Google, as we reported in Google’s 20-year deal for AEP’s Bloom fuel cells.
Why AEP Needs the Capacity
AEP had about 30 gigawatts of total available capacity last year but needs to add another 63 gigawatts by 2030, Bloomberg reports. “We expect that level of growth to continue beyond 2030,” Shane Lies, AEP’s president of nuclear development, told Bloomberg.
The Indiana agreement is the third large power agreement involving AEP made public in seven days, though it is an agreement to evaluate a plant rather than to build one. On 14 October AEP said it plans to invest about $4 billion in a 702 MW Bloom fuel-cell project near Cheyenne, Wyoming, under a 20-year power purchase agreement with Google. On 13 October Mainspring Energy said AEP agreed to buy up to 1.6 GW of its linear generators through 2034, as we reported in AEP to buy up to 1.6 GW of Mainspring generators.
Our arithmetic: the three agreements add up to 3,262 MW if all are built, about 5% of the 63 GW Bloomberg says AEP must add by 2030. Not all of it would be online by then: the Mainspring agreement runs to 2034 and the nuclear plan has a decision date of late 2029.
Planned projects using X-energy’s 80 MW Xe-100, by reactor count, as Bloomberg and AEP report them on 19 October 2026. None is under construction and the design still requires federal approval, Bloomberg reports; the Washington project would use “as many as 12.”
The Reactor
Amazon describes the Xe-100 as an 80 MW high-temperature gas-cooled reactor that uses helium as a coolant and TRISO fuel. Bloomberg notes the project would rely on unproven technology: the Sullivan County plant would potentially be the third planned project using the design, though none are under construction and the design still requires federal approval.
Dow is planning to install four of the reactors at a Texas chemical plant, and Amazon is working with Energy Northwest on a Washington state project that would use as many as 12, Bloomberg reports.
Update, 20 October: The Korean Supply Chain
Korea’s KED Global reported on 20 October 2026 that the Amazon investment “is expected to boost Korean suppliers such as Doosan Enerbility, DL E&C and Hyundai E&C.” The readable part of KED’s report does not say what role DL E&C or Hyundai E&C would play in the Indiana project, and neither AEP’s nor Amazon’s 19 October announcement names Korean suppliers for it.
Doosan’s link to the reactor design is on the record. In a release of 18 December 2025, X-energy said Doosan “will manufacture 16 sets of reactor pressure vessels, steam generator pressure vessels, and additional steel components” for the Xe-100, reserving capacity for X-energy’s first two commercial projects, and that Doosan committed to build a new SMR fabrication facility in Changwon, South Korea, with capacity for “approximately 20 Xe-100 reactors annually at full production.” That release does not mention the Sullivan County site, which was announced on 19 October 2026.
The Structural Read
As we read it, the contract terms answer the utility’s stated condition: Fehrman says the agreements “will provide all necessary capital protections and financial safeguards,” and AEP says Amazon’s contract would cover the facility and its operations.
As we read it, the plan is one of several AEP options, not a commitment: Bloomberg reports a decision by late 2029, and our arithmetic puts the three agreements involving AEP made public in seven days at 3,262 MW if all are built.
As we read it, the scale is still small against the need: Bloomberg reports AEP must add 63 gigawatts by 2030, and the 960 MW plan is one 80 MW reactor design repeated 12 times.

Three Implications
WHO CARRIES THE COST AEP says Amazon intends to buy the power under a long-term contract covering the costs of the facility and its operations; the price is not given.
A DESIGN STILL IN LICENSING Bloomberg reports the Xe-100 design still requires federal approval and that none of the planned projects is under construction.
A DECISION YEARS AWAY The companies expect to decide whether to proceed by late 2029, Bloomberg reports, citing AEP.
The framework puts it this way: “The structural bottleneck isn’t computing, it’s electrons.”
As we read it, the Indiana plan is Amazon paying for electrons years ahead: it funds development of a plant whose decision date is late 2029, Bloomberg reports. The framework was published in December 2025 and does not discuss AEP, X-energy or this project.
What Is Not Established
In the releases and the Bloomberg report we read, the cost of the plant, the size of Amazon’s development funding and the priceAmazon would pay for the power are not given; Bloomberg says terms weren’t disclosed. The project has not reached a final investment decision, and the Xe-100 design still requires federal approval. The 3,262 MW total counts the Mainspring agreement at its 1.6 GW ceiling, of which AEP has bought a first tranche of 190 MW.
This Week In The AI Supercycle
Execution Fault Lines, Concentrated Demand, and Geopolitical Firewalls
This piece is part of this week’s issue: the AI build is not short of demand for its parts. It is short of cheap money, and its end revenue rests on a narrow base of large, often venture-funded buyers.
AEP announced an agreement with X-energy to evaluate a 960 MW, 12-reactor nuclear plant at a former Indiana coal site. Amazon funds the development work and, if the plant is built, intends to buy its power under a long-term contract covering the facility’s costs, AEP says. A decision is expected by late 2029, Bloomberg reports.
