Developments: 2. ONE Nuclear has initiated large-scale energy and technology developments in Louisiana. The company first secured site control for Project Cayman, located between New Orleans and Baton Rouge. This project is designed to include a 2.88-gigawatt natural gas-fired power plant, a 700-megawatt battery storage system, and a co-located data center campus to support regional industrial demands. Following the announcement of Project Cayman, the company began environmental evaluations for Project Amberjack, a proposed small modular reactor (SMR) campus in the Ascension-Iberville industrial corridor. Project Amberjack aims to produce up to 1,000 megawatts of electricity. ONE Nuclear’s broader strategy involves utilizing natural gas-fired generation to provide immediate grid reliability, with the intention of transitioning to SMR technology as the technology matures. The company is moving into phases involving environmental field studies, technology screening, and community engagement with local officials and residents. ## Timeline ### 2026-09-08: ONE Nuclear begins environmental evaluation for Louisiana SMR project ONE Nuclear Energy has begun environmental evaluations for Project Amberjack, a proposed 1-gigawatt small modular reactor campus in Louisiana's Ascension-Iberville industrial corridor. 3 sources. https://clstr.news/cluster/one-nuclear-begins-environmental-evaluation-for-louisiana-smr-project ### 2026-08-31: ONE Nuclear announces Project Cayman energy and data center site in Louisiana ONE Nuclear has secured a site in Louisiana for Project Cayman, a 2.88 GW gas-fired power plant, battery storage system, and data center campus designed to support regional industrial growth. 3 sources. https://clstr.news/cluster/one-nuclear-announces-project-cayman-energy-and-data-center-site-in-louisiana --- Cite as: ONE Nuclear energy projects in Louisiana.
