Oklo’s planned 1.2-gigawatt nuclear reactor in Ohio, tied to Meta, targets construction start in 2028

Oklo’s nuclear project in Ohio is moving toward an identified construction timeline, and the schedule is being linked to Meta in a new report. The plan calls for a 1.2-gigawatt reactor, a scale large enough to power significant computing loads for multiple facilities, depending on output and operating terms.

The report says the project will enter pre-construction next year. Pre-construction generally refers to permitting, engineering, and early site preparation work that takes place before major construction begins, but the report does not specify which steps Oklo expects to complete in that phase.

According to the same account, the project’s next major milestone is breaking ground in 2028. Groundbreaking is typically treated as the point when heavy construction activity starts, such as civil works and major installation, though the underlying schedule details and responsible parties were not laid out in the report.

The reporting also ties the reactor to Meta through a deal described at a high level. While the story frames the development as part of Meta’s power supply pathway, it does not provide the specific commercial structure, such as the length of the agreement, pricing terms, or how output would be allocated between partners.

Oklo has not publicly detailed all of the engineering and regulatory milestones for this reactor within the materials provided here. For investors and nearby communities, the most consequential uncertainties are likely to be licensing progress, the final project budget, and how much of the reactor’s electricity would ultimately be reserved under the related arrangement.

The broader context is that data center operators and technology companies have increasingly explored long-duration power sources to support steady energy demand. Nuclear power is one option that can, in principle, provide firm generation independent of weather, though projects can face permitting, supply-chain, and construction-risk challenges.

In this case, the most important missing items are also the most specific: the report does not spell out the full terms of the Oklo-Meta agreement, the precise location of the reactor within Ohio, the plant’s expected operating start date, or whether the project will be contingent on regulatory outcomes or other conditions.

What to watch next is disclosure around the permitting and licensing path for the Ohio site, along with any formal updates from the companies involved as pre-construction approaches. Timelines can shift in nuclear development, so near-term announcements about regulatory filings and early site work would be the clearest indicators of momentum.
