A $500 Billion AI Datacenter Is Being Built in Rural Ohio. Not Everyone Is Happy About It.

Key points

• OpenAI, Nvidia and Japanese investors plan to spend $500 billion on an AI datacenter complex near Piketon, Ohio.
• The facility is designed to generate 8 gigawatts of computing power, a scale rarely attempted anywhere on Earth.
• US Energy Secretary Chris Wright and Commerce Secretary Howard Lutnick attended a groundbreaking ceremony at the site in March.
• Local boosters say the project will create thousands of jobs in a region that has long struggled economically.
• Environmental groups have raised concerns about the project's footprint, though the specific issues were not detailed in early disclosures.

Deep in the Appalachian foothills of southern Ohio, down a winding road flanked by forest, something enormous is being built. OpenAI, the company behind ChatGPT, is joining Nvidia, the chip-maker whose processors power most modern AI systems, and a group of Japanese investors to construct what is being described as one of the largest AI datacenters on the planet.

The price tag: $500 billion. The location: Piketon, a small community in Pike County that has spent decades looking for an economic lifeline.

What exactly is being built?

The project aims to produce 8 gigawatts of AI computing capacity. To put that in plain terms: a single gigawatt can power roughly 700,000 homes. This facility would not power homes; it would run the specialised computers that train and operate AI systems at a scale that requires its own power supply chain.

In March, US Energy Secretary Chris Wright and Commerce Secretary Howard Lutnick travelled to Piketon for a ceremonial groundbreaking. Japanese dignitaries joined them. The mood, by multiple accounts, was enthusiastic.

Who benefits, and who is worried?

For Piketon and the wider Pike County area, the promise is simple: jobs. Thousands of them, supporters say, in a part of Ohio where well-paid work has been scarce for a generation.

That promise carries real weight in a region that once relied on the Portsmouth Gaseous Diffusion Plant, a Cold War-era uranium enrichment facility that closed and left behind both job losses and a long environmental cleanup.

Environmental groups, however, are not celebrating. Their concerns, first reported by The Guardian, centre on what a facility this size will demand from the surrounding area, including energy consumption, water use for cooling the servers, and the broader impact on local ecosystems. The specific objections are still emerging as the project moves from groundbreaking to construction.

What does this mean for ordinary people in the region?

If the jobs materialise at the scale promised, Piketon could see a genuine economic shift. Datacenter campuses typically bring construction work first, then permanent roles in operations, security and maintenance.

The catch is that large infrastructure projects frequently promise more jobs than they deliver, and the timeline between groundbreaking and full employment can stretch years. Residents are right to welcome the possibility while watching the specifics closely.

For people living near the site, the environmental questions matter most practically: what happens to local water sources, and who monitors the power infrastructure needed to run 8 gigawatts of computing around the clock.

Common questions

Why does an AI datacenter need so much power?

AI systems, especially the large models behind tools like ChatGPT, require thousands of specialised chips running continuously. Those chips generate enormous heat and need constant electricity, making large datacenters among the most energy-intensive buildings humans currently construct.

Is $500 billion actually being spent all at once?

No. Large infrastructure investments like this are typically staged over many years, with funding released in phases as construction milestones are met. The headline figure represents a long-term commitment, not a single upfront payment.
