“Caturus has secured a significant 20-year sales and purchase agreement (SPA) between its Commonwealth LNG project and Aramco Trading, a subsidiary of Saudi Aramco. The deal commits Aramco Trading to purchase 1 million tonnes per annum (Mtpa) of LNG from the 9.5 Mtpa export facility under development in Cameron Parish, Louisiana. This offtake agreement boosts the project’s commercial progress, bringing contracted capacity to approximately 84% and advancing it toward a final investment decision (FID) expected in the coming months, with operations targeted for 2030.”
Commonwealth LNG Bolsters Momentum with Aramco Offtake
The LNG sector continues to see robust demand for long-term U.S. supplies, and the latest development underscores this trend. Caturus, through its Commonwealth LNG affiliate, has finalized a binding 20-year SPA with Aramco Trading Americas LLC, the trading arm of Saudi Aramco. This agreement positions Aramco as a key buyer for 1 Mtpa of the facility’s output, representing a substantial portion of the project’s planned nameplate capacity of 9.5 Mtpa.
Located on the U.S. Gulf Coast in Cameron Parish, Louisiana, the Commonwealth LNG export terminal benefits from strategic advantages, including proximity to abundant natural gas resources from the Haynesville and Permian basins, access to existing pipeline infrastructure, and efficient marine facilities for large-scale exports. The project is designed as a mid-scale liquefaction facility, emphasizing cost efficiency, lower emissions profiles compared to some larger plants, and flexibility in operations to meet evolving global energy needs.
This SPA marks a pivotal milestone for Commonwealth LNG. Prior to this agreement, the project had already secured long-term commitments from several prominent international players. These include major energy traders and utilities such as Glencore, JERA (Japan’s largest power generator), Petronas of Malaysia, Mercuria, and EQT. With the addition of Aramco Trading’s 1 Mtpa commitment, the facility’s capacity is now approximately 84% subscribed under long-term contracts. This high level of offtake subscription significantly de-risks the project and provides a strong foundation for financing and construction activities.
Aramco Trading’s entry into this deal aligns with the company’s broader strategy to expand its global LNG portfolio. As one of the world’s largest energy companies, Saudi Aramco is actively building its presence in natural gas and LNG markets to diversify beyond traditional crude oil dominance. The U.S. Gulf Coast has emerged as a preferred source for flexible, reliable LNG supplies, particularly amid growing Asian and European demand. By securing this volume from Commonwealth LNG, Aramco Trading gains access to competitively priced American LNG, which can serve as a key component in its trading and supply optimization efforts across international markets.
From the developer’s perspective, the agreement highlights the attractiveness of U.S. LNG projects in the current market environment. Global LNG demand remains elevated due to energy security concerns, the transition away from coal in key regions, and the need for dispatchable fuel in power generation. U.S. exporters benefit from abundant feedstock, transparent pricing linked to Henry Hub, and the ability to offer destination-flexible contracts that appeal to buyers seeking portfolio diversity.
The Commonwealth LNG project is structured to deliver first LNG cargoes around 2030, assuming timely achievement of FID and subsequent construction phases. The facility will feature modular liquefaction trains, which allow for phased development and potential cost savings. Environmental considerations have been integrated into the design, with efforts focused on methane emissions reduction, efficient power usage, and compliance with regulatory standards.
This transaction also reflects the deepening energy ties between the United States and Saudi Arabia. While the two countries have long collaborated in oil markets, expanding cooperation into natural gas and LNG represents a new dimension. Aramco’s investment in U.S. LNG offtake supports American energy exports while providing Saudi interests with reliable supply sources outside the Middle East.
For the broader U.S. LNG industry, deals like this reinforce the Gulf Coast’s role as the epicenter of global liquefaction capacity growth. With multiple projects advancing toward FID or under construction, the U.S. is on track to maintain its position as the world’s leading LNG exporter in the years ahead.
The SPA becomes fully effective upon satisfaction of standard conditions, including a positive FID on the Commonwealth LNG project. Caturus continues to engage with potential additional offtakers to fully subscribe the remaining capacity, positioning the project for a robust commercial launch.
