Louisiana plans to add 5 GW of new power capacity through three projects that combine natural gas, battery storage, and advanced nuclear reactors. The initiative aims to meet the growing electricity demands of data centers, advanced manufacturing, and other industrial users. Rather than relying on a single source of power, the plan distributes capacity across three projects with different roles and timelines. Project Cayman will provide the largest share, with an expected 2.88 GW of natural gas generation and battery storage. The project may also include a data center technology park, allowing large customers to access dispatchable power close to their operations.
Power Generation Capacities of Different Projects
Project Barracuda will add another 1.2 GW of natural gas generation, equipped with 300 MW/1.2 GWh of battery storage. The planned energy park could support up to 1 GW of critical data center IT capacity, becoming a dedicated power and computing hub. Project Amberjack takes a different path, serving as a standalone small modular reactor park with a target of 1 GW of advanced nuclear power generation.
These projects are designed to address different aspects of the electricity challenge. Natural gas generation will provide dispatchable power, batteries will help manage demand and storage, and nuclear will offer a more long-term stable source of power. Cayman has already secured site control through binding letters of intent. The project's development will be phased based on customer demand, fuel availability, utility requirements, environmental assessments, permits, and financing. Barracuda is also in phased planning, with its generation, storage, and data center components scalable as customer demand grows.
Challenges of the Amberjack Project
Amberjack is at an earlier stage, with the project having secured site control, but the company still needs to conduct technical and environmental studies to determine the reactor technology and final plant configuration.
ONE Nuclear's CEO Richard Taylor stated, "The Louisiana Trilogy offers three different yet complementary solutions to address the rising electricity demand in the US. Cayman provides scale, Barracuda links dedicated power with digital infrastructure, and Amberjack creates a disciplined path for advanced nuclear." The integrated plan targets approximately 4.08 GW of natural gas generation from Cayman and Barracuda, plus up to 1 GW of nuclear capacity from Amberjack.
These figures are not guaranteed as generation capacity, as the projects are still contingent on final engineering, grid interconnection, permits, customer agreements, financing, and other development decisions.
Amberjack is the most technically challenging part of the portfolio. The proposed park will use multiple small modular reactors, but the company has not yet selected a specific reactor technology. Planned work includes geotechnical and environmental studies, cooling water and logistics assessments, transmission analysis, and discussions with potential technology suppliers. The company also plans to continue engagement with the Nuclear Regulatory Commission and local communities. ONE Nuclear's Chief Development Officer Chris Hansmeyer said, "The ambition of the Louisiana portfolio lies in Louisiana's extraordinary opportunity."
These projects are complementary but not interdependent. We can advance proven dispatchable generation and storage to meet near-term needs, build dedicated infrastructure for digital and industrial customers, and provide a rigorous, site-specific path for advanced nuclear.
This approach reflects a broader push to build power infrastructure around the rapidly expanding demand for data centers, while also considering nuclear as a long-term option. ONE Nuclear plans to hold a public information meeting in October 2026 to explain these projects, discuss environmental and infrastructure work, and gather community feedback. The three projects are still at different stages of development and have not yet begun commercial power generation.

The Future Direction of Louisiana's Power Infrastructure
Louisiana's power plan demonstrates a focus on diversified energy sources, particularly in response to the growing demand from data centers. By combining natural gas, battery storage, and advanced nuclear technology, these projects can provide immediate dispatchable power while ensuring long-term stability. As electricity demand rises, this comprehensive strategy helps enhance energy security and reduces reliance on a single energy source. Additionally, the complementary nature of the projects offers flexibility for future energy development, allowing for adjustments based on market needs.
