How a Decommissioned Uranium Plant Powers Data Centers

A data center is being built on the grounds of a former uranium enrichment facility in southern Ohio. Read that sentence again.

It's not a science fiction premise. It's infrastructure development logic at its most elegant — and it points toward a model that could quietly reshape how and where the next generation of data centers gets built.

The digital economy's appetite for power is relentless. Hyperscalers and colocation operators are hunting for sites that can deliver reliable, large-scale energy supply without the 3-to-7-year wait that comes with building new transmission infrastructure from scratch. Meanwhile, thousands of acres of former industrial land — some of it carrying serious federal cleanup history — sit underleveraged across the country. The match between these two realities is becoming harder to ignore.

The Case for Decommissioned Sites

Former uranium enrichment plants weren't chosen randomly. The federal government sited them with deliberate logic: access to massive electrical infrastructure, proximity to water sources for cooling, and enough geographic isolation to minimize risk. Those same attributes — minus the enrichment — are exactly what data center developers need.

The infrastructure that made these facilities dangerous is now precisely what makes them valuable.

The Portsmouth Gaseous Diffusion Plant in Piketon, Ohio — the site referenced here — consumed more electricity at peak operation than some mid-sized cities. The DOE's Oak Ridge-connected uranium processing network was engineered for uninterrupted, industrial-scale power draw. That kind of electrical backbone doesn't get built twice. It gets inherited.

Decommissioned doesn't mean demolished. Remediation timelines for former uranium sites typically run decades, and during that window, portions of the property — particularly areas cleared of contamination — become available for adaptive reuse. The Portsmouth site has undergone years of decontamination and decommissioning (D&D) work managed by the DOE's Office of Environmental Management. Sections are actively being repositioned for industrial redevelopment. Placing a data center on a cleared portion of that site isn't reckless — it's the result of deliberate policy and years of groundwork.

The historical precedent here matters. Federal sites like this were built with public investment, decommissioned with public investment, and now they have an opportunity to generate economic return for the communities that absorbed the risk of hosting them for generations. Gallia County and Pike County — these are rural Appalachian communities that watched a major employer wind down. A data center campus isn't a consolation prize. For regions with thin economic margins, it's a genuine anchor.

Energy Supply That's Already There

Here's the part that most coverage misses: the power grid interconnection at a site like Portsmouth isn't just "nearby." It was purpose-built for industrial-scale continuous load. We're talking about transmission infrastructure that once fed an operation drawing hundreds of megawatts around the clock.

Most greenfield data center projects spend years just negotiating grid interconnection — at a former enrichment site, that problem is largely pre-solved.

For context, a large hyperscale data center campus might consume 100–500 MW continuously. Grid interconnection at that scale, built from scratch, can take five to ten years and hundreds of millions of dollars. Inheriting hardened transmission infrastructure from a federal industrial site compresses that timeline dramatically.

The technologies enabling this transformation layer on top of that existing backbone. On-site renewable generation — solar arrays, potentially wind — can be co-located on the cleared acreage. Battery storage systems smooth the intermittency gaps. And there's a longer-term angle that's genuinely compelling: the Portsmouth site sits within Ohio's nuclear energy ecosystem, and the DOE has explored small modular reactor (SMR) deployment at former nuclear complex sites. If SMR commercialization accelerates, sites like this could offer carbon-free, always-on baseload power that no solar farm alone can promise.

The energy redundancy story writes itself. Data centers demand uptime. A site with legacy industrial power infrastructure, supplemental renewables, and a potential nuclear energy pathway on the horizon is, from a resilience standpoint, exceptional.

The Economics of Inherited Infrastructure

Developers who understand industrial site repurposing know that the headline cost of acquiring a complex former federal site can look alarming — and then you run the actual numbers on what you're getting.

Skip the transmission build-out cost. Inherit access roads, security perimeter infrastructure, water management systems, and, in many cases, existing structures that can be adapted. The bones of an industrial campus that the federal government built over decades don't come cheap when you try to replicate them. When you can acquire access to them through redevelopment agreements, the economics shift substantially.

Federal and state incentive structures add another layer. The Inflation Reduction Act created significant incentives tied to energy communities — defined partly as areas affected by the closure of fossil fuel or energy-related facilities. Former uranium processing sites sit squarely in the spirit of that framework. Ohio has its own economic development tools aimed at brownfield redevelopment and job creation in distressed regions. Stack those incentives against a project that can claim infrastructure development, renewable energy integration, and rural job creation, and the financing picture gets considerably more attractive.

The real competitive advantage isn't cheap land — it's the years of permitting and infrastructure work that someone else already did.

For data center operators under pressure to accelerate deployment timelines, that pre-existing work has enormous value. Every month shaved off a construction schedule against a backdrop of AI-driven demand growth is real money.

Sustainability Framing That Actually Holds Up

There's a version of the "brownfield redevelopment is green" argument that's mostly marketing. This isn't that.

Placing a data center on a remediated former industrial site genuinely reduces pressure on undeveloped land. It concentrates an energy-intensive use case on a location that's already been industrially impacted, rather than carving into greenfield or agricultural land. The local ecosystem benefits are real when you consider the alternative: a comparable data center development on virgin land requires new roads, new transmission corridors, new water infrastructure — all with associated land disturbance.

The carbon math favors this model when renewable energy is integrated on-site. A data center drawing from solar generation co-located on former industrial acreage, backed by storage, has a credible path to the kind of emissions profile that meets corporate sustainability commitments. The renewable energy component isn't greenwashing here — it's structurally integrated into a site that has the acreage and grid capacity to support it.

For ESG-conscious operators, the community dimension matters too. Data centers on decommissioned sites bring construction jobs, permanent operations employment, and tax base to regions that have often spent years in economic contraction since the original industrial facility wound down.

What Developers Need to Know Before Moving In

None of this is without complexity. Site repurposing at former uranium facilities requires careful navigation, and the gap between "the site is being redeveloped" and "we can break ground on a data center" involves real work.

Regulatory coordination is multi-layered. The DOE's Office of Environmental Management, the Nuclear Regulatory Commission, the EPA, and state environmental agencies all have equities at former nuclear complex sites. Developers pursuing data centers on decommissioned sites need experienced environmental counsel and a realistic timeline for site assessment, clearance documentation, and ongoing monitoring requirements that may attach to remediated parcels.

Subsurface conditions demand rigorous due diligence. Even on cleared portions of a remediated site, understanding what's in the ground — and what covenants or restrictions attach to the parcel — is non-negotiable. This isn't a standard brownfield situation. The regulatory history is more complex, and the documentation requirements are commensurately higher.

The developers who succeed at this will be the ones who treat regulatory engagement as a competitive advantage, not an obstacle.

Power infrastructure inheritance also requires assessment. Aging transmission equipment built for Cold War-era industrial loads needs evaluation before a data center operator can rely on it. That's engineering work, not a dealbreaker — but it's work that needs to be scoped and budgeted honestly.

Where This Goes Next

The Ohio project isn't a curiosity. It's a proof of concept for a model that should get a lot more attention.

There are former DOE complex sites across the country — in Tennessee, Kentucky, Washington state, South Carolina — each with some variant of the same story: massive historical infrastructure investment, federal remediation programs underway, surrounding communities hungry for economic replacement, and energy infrastructure that would cost billions to replicate on a greenfield.

The data center industry is in a land and power sprint right now. AI infrastructure demand is pulling forward construction timelines across the sector. The operators and developers who find non-obvious sites with pre-existing power capacity will have a structural advantage over competitors waiting years for new grid interconnections.

A decommissioned uranium plant powering a data center sounds like an unlikely pairing. But when you understand why those sites exist, where they are, and what they contain — it starts to sound like the most logical real estate play nobody's talking about loudly enough yet.
