Pacific LNG Export Cooperation for Asian Supply

TotalEnergies and Sempra Infrastructure are collaborating on the commissioning and commercial deployment of the ECA LNG Phase 1 export terminal on Mexico's Pacific coast. The project establishes an integrated LNG export route for supplying Asian and Pacific Basin markets using U.S. natural gas, supporting the development of regional LNG infrastructure and long-term energy supply chains.

Project Scope and Industrial Context
The cooperation combines Sempra Infrastructure's role as project developer and operator with TotalEnergies' long-term LNG offtake and global trading capabilities. The partners address the technical and logistical challenges of creating a new LNG export corridor that connects upstream gas production in the Permian Basin with international LNG customers through Pacific shipping routes.

The collaboration was required because the project integrates multiple infrastructure elements, including cross-border natural gas transportation, liquefaction, marine export facilities, and international LNG marketing. Such integration requires coordinated engineering, operational planning, commissioning activities, and commercial scheduling across the LNG value chain.

The facility primarily serves LNG trading, power generation, industrial energy supply, and natural gas import markets across Asia and the Pacific Basin. Its location enables shorter shipping distances compared with U.S. Gulf Coast export terminals, improving transport efficiency and vessel utilization.

Technical Solution and Partner Responsibilities
ECA LNG Phase 1 consists of a single-train liquefaction facility with a nominal production capacity of 3.25 million tonnes of LNG per year. Feed gas is supplied from the Permian Basin in Texas and New Mexico through the North American pipeline network before liquefaction and marine export.

Sempra Infrastructure is responsible for engineering, construction, commissioning, operation, and integration of the export terminal. The project also incorporates existing regasification infrastructure at the site, allowing shared facilities to reduce construction complexity and optimize capital investment.

TotalEnergies holds a 16.6% ownership interest and has secured long-term rights to purchase 1.7 million tonnes of LNG annually over a 20-year period after commercial operations begin. During the commissioning and production ramp-up phase, the company acts as the sole LNG offtaker, supporting operational stabilization and cargo scheduling.

Deployment and System Integration
The first LNG cargo has been exported while the terminal remains under commissioning. Commercial operation is scheduled following substantial completion of Phase 1, after which long-term supply agreements will become fully effective.

The export terminal integrates existing site infrastructure with new liquefaction and marine loading systems, enabling phased commissioning while maintaining operational continuity. A second expansion phase is under development to increase future production capacity at the same location.

Operational Impact
The cooperation strengthens digital infrastructure and LNG supply chain integration between North American gas production and Asian demand centers. By combining liquefaction capacity, long-term commercial agreements, and optimized Pacific shipping routes, the project improves export flexibility, reduces transportation distances, and supports predictable LNG delivery through integrated infrastructure planning.
