The Short Version
A company called The Nuclear Company wants to build up to six large nuclear reactors beside the Ohio River in rural Lewis County, Kentucky. The state has never had a nuclear power plant.
If all six were built, it would be the biggest nuclear power site in the country. Site preparation is planned to start in 2028.
Why it matters: tech companies building huge computer centers for artificial intelligence want steady, around-the-clock electricity at exactly this size. The company has the land and has chosen a reactor. It has not said who would buy the power or who would pay to build it.
On October 21, 2026, The Nuclear Company announced Prosperity One, according to a release distributed through PR Newswire. Prosperity One is a proposed nuclear energy campus on the Ohio River in Lewis County, eastern Kentucky. It could host up to six Westinghouse AP1000 reactors totaling about 6.6 gigawatts (GW). A gigawatt is 1,000 megawatts, the scale of a large power station. If fully built, the campus would be Kentucky’s first commercial nuclear plant. The company says it would also be the largest nuclear generating complex in the United States and one of the largest in the world.
The company says it controls the site, which is owned by lifelong Lewis County resident Sam Howard. It plans to begin site development work in 2028 and is aiming to secure the federal approvals needed to start construction on that timeline. Separately, Lewis County is applying to the Kentucky Nuclear Energy Development Authority for designation as a ‘nuclear-ready community.’
Executive Summary
Prosperity One is a site announcement for a multi-reactor nuclear campus, not a construction decision. The Nuclear Company has secured control of land on the Ohio River and named its reactor technology: Westinghouse’s AP1000, the large pressurized-water design now running at Georgia’s Plant Vogtle. It has also lined up visible local support. County leaders launched a nuclear-readiness initiative unanimously in July 2026, held public hearings, and this month voted by a wide margin to apply for state designation.
The scale is what makes the announcement notable. At roughly 6.6 GW, a fully built campus would deliver firm power on the order now being discussed for the largest new electricity users, a group that increasingly includes AI data-center campuses. Firm power means electricity available around the clock regardless of weather. The company presents the project around reliable power for Kentucky, local jobs and a stronger tax base. It has not named a customer, utility partner, cost estimate or financing plan.
The next milestones are therefore commercial and regulatory, not geographic. They include an offtake agreement (a long-term contract to buy the plant’s output), a financing structure, a licensing filing with the Nuclear Regulatory Commission, and a transmission interconnection plan. Those will show whether Prosperity One becomes a buildable project or remains a well-sited option.
What Prosperity One Already Has
The announcement covers the early, local layer of a nuclear project. The company has site control, and the landowner says he joined the effort so his nine grandchildren can stay in a county he describes as among Kentucky’s highest in unemployment. The county has also run a public process and voted to seek the state’s nuclear-ready designation. Many energy projects stall at the local layer. Prosperity One, by the company’s account, has cleared that step early.
The team also carries relevant experience. Chief Nuclear Officer Joe Klecha is a former licensed senior reactor operator with 33 years in nuclear power, from US Navy submarines to operations leadership at large reactor fleets. He held construction and operational-readiness leadership roles at Vogtle Units 3 and 4, the most recent AP1000s completed in the US. The company says its services division has performed maintenance at more than 40 percent of America’s operating nuclear plants. Together these support the claim that the team knows how existing reactors are run and maintained. Executing a six-unit new build is a different and much larger undertaking.
The early work program is a standard list for a greenfield nuclear site. It includes detailed site characterization, geotechnical surveys (testing the ground the reactors would sit on), environmental reviews, transmission interconnection planning and preparation for federal licensing. The company also says it will address transportation, housing, emergency preparedness and water use. For a campus drawing cooling water from the Ohio River, water use is a material planning issue, not a footnote.
Why 6.6 GW Makes the Buyer the Deciding Question
Six AP1000 units at the stated total works out to roughly 1.1 GW each. A campus of that size is beyond what a rural county or a single regional load would absorb on its own. It is the size class at which the conversation turns to the largest new loads on the US grid, and the largest new loads being planned today are AI data-center campuses measured in hundreds of megawatts up to gigawatts. That is the AI-infrastructure relevance of Prosperity One. The Nuclear Company has not linked the campus to data centers or named any prospective customer.
Here is the mechanism that puts the buyer at the center. Reactors of this size cost far more up front than gas plants and take years to build. Lenders and investors fund them against predictable revenue over decades. That revenue can come from a regulated utility recovering costs from ratepayers, as at Vogtle, from long-term contracts with large power users, or from some combination. Whichever route applies, someone has to commit to buying the output before anyone commits capital to the concrete. The site is controlled, local support is documented, and the reactor design is already licensed and operating at Vogtle. Of the elements a nuclear project needs, the commercial commitment is the one that remains entirely undisclosed.
Several groups are directly affected by how that question resolves. Data-center developers looking for firm, carbon-free power in the Ohio Valley gain a possible long-dated supply option, but not a near-term one. Utilities and the regional grid operator would need to plan for, and potentially build transmission around, a very large new source of supply. Kentucky ratepayers have a stake in whether any of the cost lands in regulated rates. Until a buyer appears, Prosperity One signals where large-scale nuclear could go. It is not yet capacity anyone can plan around.
The Vogtle Credential and the 2028 Clock
Vogtle Units 3 and 4 are the reference point for any AP1000 project in America. They proved the design can be built and operated in the US: the units entered commercial service in 2023 and 2024. They also ran years behind schedule and well over original cost estimates. Industry advocates have argued that later AP1000s should be cheaper and faster because the design is finished and the workforce has now done it once. Prosperity One’s leadership includes people who worked on Vogtle, which supports that argument. Proving it requires a contracted build, and the company has not yet described one.
The 2028 date needs careful reading. The company says it plans to begin site development work in 2028 and aims to obtain the federal approvals needed to start construction on that timeline. It says it will engage the Nuclear Regulatory Commission ‘through established licensing processes.’ It has not stated what it has filed, which license pathway it will use, how six units would be phased, or when the first unit would produce power. For a buyer weighing the campus against near-term alternatives, the first-power date matters more than the groundbreaking date, and that date is not in the announcement.
Gas Bridges, Small-Reactor Pilots and the Case for Large Reactors
Large power users now have a few broad options for firm power: natural gas plants deployed as a bridge, small modular reactor (SMR) pilots that promise factory-built units in smaller increments, and large conventional reactors. Prosperity One is a clear bet on the third option. It uses a design that already has a US operating record and stacks enough units in one place to spread site, licensing and workforce costs across a lot of output.
The trade-off is concentration. A single six-unit campus puts a great deal of capital, schedule risk and regional grid dependence in one location. SMR proponents argue that smaller units reduce exactly those risks, though at commercial scale those designs remain earlier in development. Neither path has settled the debate. What Prosperity One adds is a concrete, sited proposal for the large-reactor approach at a scale few US projects have attempted, and a test of whether that approach can attract the long-term commitments it needs.
Background
The United States has built very few new reactors in recent decades. Vogtle Units 3 and 4 in Georgia were the first AP1000s completed in the country. They entered service in 2023 and 2024 after significant delays and cost overruns, and they are now the reference case for anyone proposing new large reactors. Interest in nuclear power has since grown, driven by forecasts of rising electricity demand, much of it tied to data centers, and by buyers seeking firm, carbon-free supply.
Kentucky has long been a coal and energy-producing state, and it lifted its moratorium on new nuclear construction in 2017. The state has since established the Kentucky Nuclear Energy Development Authority, which handles the nuclear-ready community designations that counties such as Lewis County are now seeking.
