ONE Nuclear Unveils 2.88 GW Gas Plant for Louisiana AI Campus
A binding letter of intent secures site control for Project Cayman, combining natural gas generation, battery storage, and high-density compute infrastructure.
ONE Nuclear Energy has executed a binding letter of intent to secure site control for Project Cayman in Ascension Parish, Louisiana. The project pairs a massive 2.88-gigawatt natural gas power plant and a 700 MW battery storage system with a co-located hyperscale AI data center campus. The development highlights how AI infrastructure developers are turning to dedicated fossil fuel generation to bypass electric power grid capacity constraints.
Key details
Under the agreement with a local landowner group, ONE Nuclear Energy secured site control near the RiverPlex MegaPark along the Mississippi River. Project Cayman features a 2.88-gigawatt natural gas-fired power plant paired with a 700-megawatt, 2.88-gigawatt-hour battery energy storage system (BESS). The site will co-locate a high-capacity AI data center campus directly adjacent to the generation assets.
Despite the developer's name, no nuclear reactors are currently planned for the initial facility. Located in Ascension Parish, the campus is situated near major industrial projects and new high-voltage transmission lines being built by Entergy. The dedicated power architecture is designed to supply continuous, dispatchable energy to high-density compute racks without relying on public utility allocations.
Why this matters
Hyperscale AI data centers require continuous, gigawatt-scale power that public utility grids struggle to supply. By building an off-grid natural gas plant and battery storage system directly alongside compute infrastructure, ONE Nuclear bypasses multi-year utility interconnection queues. However, adding 2.88 gigawatts of gas generation significantly increases carbon emissions and local environmental pressure in the Gulf Coast industrial corridor.
Context
Project Cayman reflects a growing nationwide trend where AI developers build behind-the-meter fossil fuel generation. Similar off-grid gas projects have been launched across West Texas, Pennsylvania, and Virginia as utilities face interconnect backlogs exceeding hundreds of gigawatts. The project also follows recent industrial expansion in Ascension Parish, including new steel manufacturing and logistics facilities.
What happens next
ONE Nuclear will advance community outreach, including public information meetings with local parish officials and regulatory agencies. The company will seek environmental permits and fuel supply agreements while evaluating potential future integration of small modular nuclear reactors.
