Short answer: The October 16, 2024 headlines joined two different developments. The Department of Energy (DOE) opened a funding program offering up to $900 million for selected Generation III+ small modular reactor (SMR) projects; it did not write Amazon a $900 million check. Separately, Amazon anchored an approximately $500 million investment round for X-energy and announced development agreements in Washington and Virginia.
Neither announcement meant an Amazon-owned reactor was ready to supply a data center. The projects still require design work, licensing, site studies, fuel, financing, construction and commissioning. DOE’s program has since moved forward: the solicitation was reissued in March 2025, applications closed April 23, 2025, and DOE later selected TVA and Holtec for $400 million Tier 1 awards each.
What happened on October 16, 2024?
The date marked a convergence of federal policy and private investment, not a single joint transaction. DOE’s initiative began with a June 17, 2024 Notice of Intent. The October 2024 solicitation put the proposed funding structure into practical terms, while Amazon and X-energy announced a separate corporate financing and project-development strategy.
| Announcement | What it was | What it was not |
|---|---|---|
| DOE | Up to $900 million for selected Gen III+ light-water SMR teams and follow-on projects | An immediate payment to Amazon or a reactor builder |
| Amazon/X-energy | An approximately $500 million Series C-1 financing round anchored by Amazon, plus project agreements | A completed reactor, construction order or guaranteed power delivery |
| Amazon/Dominion | An agreement to explore an SMR near Virginia’s North Anna station | A final investment decision or operating plant |
DOE’s program details are set out on its Generation III+ SMR program page and in the original funding document.

What DOE’s $900 million program actually funds
Tier 1: first-mover teams
Up to $800 million was designated for as many as two teams. A qualifying team was expected to bring together a utility, reactor vendor, constructor and an end user or electricity off-taker. The aim was to help a first commercial deployment overcome licensing, engineering, supply-chain and construction barriers. DOE described project periods of up to about 10 years for grid-scale deployments.
Tier 2: fast followers
Approximately $100 million was intended for multiple projects that could address design, licensing, supplier-development and site-preparation obstacles. These activities were expected to run for up to about five years. The purpose was to make later units less dependent on first-of-a-kind work.
This structure matters financially. A Notice of Intent and a solicitation are opportunities to apply, not proof that the full amount has been awarded or spent. Awards can be cost-shared, conditioned on milestones and limited to eligible recipients. Readers should distinguish a federal funding opportunity from a grant agreement, loan, tax credit or private equity investment.
What “Generation III+ SMR” means
An SMR is a smaller reactor unit designed for modular manufacturing and repeat deployment. “Generation III+” generally refers to an evolutionary class of reactors with enhanced safety systems, modern controls and technology that is closer to today’s light-water reactors than many more experimental concepts.

That label does not cover every advanced reactor. X-energy’s Xe-100, the design associated with Amazon’s investment, is an advanced high-temperature gas reactor. DOE treats the Gen III+ light-water program as distinct from other parts of its advanced-nuclear portfolio. Calling the $900 million program a subsidy for all “next-generation” reactors would therefore be inaccurate.

What Amazon announced with X-energy
Corporate financing
According to X-energy’s announcement, Amazon’s Climate Pledge Fund anchored an approximately $500 million Series C-1 round. Other participants included Citadel founder Ken Griffin, affiliates of Ares Management, NGP and the University of Michigan.
The financing was directed toward X-energy’s reactor design and licensing work and the first phase of a TRISO-X fuel-fabrication facility in Oak Ridge, Tennessee. It was investment in a reactor company and its fuel capability—not $500 million earmarked solely for pouring concrete at a reactor site.
Energy Northwest in Washington
Amazon and X-energy initially supported a proposed four-unit project totaling 320 megawatts in central Washington. The concept could expand to 12 units and 960 megawatts. The proposed location is associated with Energy Northwest’s Columbia Generating Station and the former Washington Nuclear Project 1 site.
DOE environmental documentation describes Amazon’s initial commitment as funding feasibility and site-characterization work. Boreholes, environmental reviews and engineering studies are prerequisites; they are not evidence that an operating plant is under construction. See the agency’s site-characterization record.
The 5-gigawatt ambition
Amazon and X-energy said they aimed to bring more than 5 gigawatts of projects online in the United States by 2039. That is a commercial target, not 5 gigawatts already financed, licensed, built or connected to the grid. Reaching it would require multiple projects to pass regulatory, manufacturing and construction milestones.
Rank #3
What Amazon and Dominion agreed to in Virginia
Amazon and Dominion Energy agreed to explore an SMR near Dominion’s North Anna nuclear station. Amazon described potential regional capacity of at least 300 megawatts in an area where Dominion expected substantial electricity-demand growth over the following 15 years. Its announcement characterizes the effort as exploration and evaluation.
There was no final reactor order, completed power-purchase agreement or guarantee that 300 megawatts would be delivered. The arrangement could ultimately involve utility ownership, project investment, long-term contracts or other structures; the original announcement did not establish that Amazon would own and operate the plant.
Why data centers are looking at nuclear power
Cloud computing and artificial-intelligence facilities require large, continuous electricity supplies. Nuclear plants can provide firm, low-carbon electricity around the clock, whereas wind and solar output varies and need storage, transmission or other firming resources to match demand at every hour.
That reliability is the commercial attraction. It is not a guarantee that nuclear will be cheaper or faster than renewables, gas generation, batteries or grid upgrades. DOE has linked rising electricity demand from data centers, AI and industry to the need for additional generation; contemporaneous coverage described that connection.
Amazon’s approach also differs from simply buying power from an existing reactor. It combined equity in a reactor developer, support for a utility-led project and exploration of another utility project. Depending on the final contracts, electricity could be sold through a utility or the wider grid rather than delivered through a private wire directly to one data center.

Why a press release is not a reactor
Licensing
A new design must undergo regulatory review, safety analysis, site approval and construction and operating authorization. DOE identifies licensing as a barrier its program is intended to address. A design that is still in review cannot be treated as an available power source.

Modular construction may reduce repetition and factory work, but projects still need nuclear-grade manufacturing, quality assurance, security, emergency planning, skilled labor, financing and grid interconnection. “Small” describes the unit; it does not make a project automatically inexpensive or quick.
Fuel
Fuel requirements depend on the design. Some advanced reactors require high-assay low-enriched uranium (HALEU), and DOE has offered up to $800 million through contracts to build domestic HALEU services. The agency’s fuel-supply announcement illustrates why enrichment and fabrication capacity can affect schedules. Gen III+ light-water SMRs should not be assumed to have identical fuel needs.
Sites, transmission and communities
Projects need suitable land, cooling arrangements where applicable, seismic and environmental studies, transmission capacity, local approvals and community support. Public questions include who pays for transmission, who bears cost overruns and how utility customers are protected. DOE’s framework also addresses community engagement, quality jobs, disadvantaged-community benefits and Justice40 considerations.
Demand uncertainty
Data-center plans can change in location, timing, efficiency and workload mix faster than a nuclear project can be developed. A utility and its regulators therefore need contracts and cost protections that remain workable if projected demand is delayed or reduced.

What changed after the 2024 headlines?
DOE reissued the $900 million solicitation in March 2025, requiring previous applicants to resubmit under the new guidance. Applications closed April 23, 2025. DOE’s current program page later listed these Tier 1 selections:
- Tennessee Valley Authority: $400 million to advance GE Vernova Hitachi’s BWRX-300 at the Clinch River site in Tennessee and related supply-chain work.
- Holtec: $400 million to deploy two SMR-300 reactors at the Palisades site in Michigan.
- Tier 2: DOE listed awards announced in May 2026 for fast-follower activities.
These selections are not Amazon awards and do not convert the Washington or North Anna proposals into operating projects. They do show that the federal program progressed beyond the 2024 solicitation. The latest program status is maintained by DOE.
How to judge the financial significance
- Identify the money: Is it a grant, cost share, equity investment, loan, tax credit or nonbinding intent?
- Check project maturity: Is the project at feasibility, site characterization, design certification, construction licensing, final investment decision, construction or operation?
- Look for a binding power contract: A target or memorandum is different from a signed long-term purchase agreement.
- Test the schedule: Licensing, manufacturing, fuel, construction and commissioning must fit before claimed delivery dates are credible.
- Ask who carries risk: Customers, taxpayers, shareholders and ratepayers can face different exposure if costs rise.
For households and ordinary utility customers, the relevant issue is not whether Amazon has announced nuclear ambitions. It is whether regulators approve projects, how costs are allocated and whether new generation improves reliability without imposing unreasonable rates.
Bottom line
DOE’s $900 million initiative created a pathway for selected Gen III+ SMR deployments; it was never an immediate Amazon subsidy. Amazon’s October 2024 announcements represented a serious corporate strategy—investment in X-energy, a proposed Energy Northwest project and exploration near North Anna—but all remained development-stage commitments. The announcements mattered because hyperscale electricity demand could provide anchor customers for new reactors. They did not establish near-term Amazon-owned nuclear power, completed financing for a reactor fleet or guaranteed delivery of 5 gigawatts by 2039.
