Summary

Port Arthur LNG, a Texas-based development set to be brought online in 2027, is poised to revolutionize U.S. energy exports. More than $26 billion is to be invested in various phases of Port Arthur LNG through 2031.

A Decade of Development

The U.S. leads the world in liquefied natural gas (LNG) exports, with domestic developers hitting a record-high total volume for offtake agreements in 2025. One of the most widely anticipated developments in the global field is the Port Arthur LNG complex, a joint venture between Sempra Infrastructure and ConocoPhillips on the Texas Gulf Coast. According to Industrial Info Resources data, more than $26 billion is to be invested in various phases of Port Arthur LNG through 2031.

Industrial Info Resources is tracking more than $350 billion worth of active and proposed LNG-production projects across the U.S., with construction kickoff dates ranging from this June to March 2031. Other major developers in the field include Venture Global LNG LLC, NextDecade, TotalEnergies and Cheniere Energy Incorporated.

Altogether, Port Arthur LNG has been in development for more than a decade. The nascent plant received authorization from the U.S. Department of Energy (DOE) in 2015 to export any eventual product to countries with which the U.S. shares a Free Trade Agreement (FTA); in mid-2019, the U.S. Federal Energy Regulatory Commission (FERC) granted the parent companies permission to locate, build and operate a natural gas liquefaction and export terminal, while the DOE authorized it to export any eventual product to non-FTA countries.

Industrial Info Resources has been tracking progress on the Port Arthur LNG complex since its earliest days. The initial project report, released in April 2015, indicated the first two trains could be completed as early as 2019. But, as with almost any LNG project of comparable size, numerous hurdles popped up over the years that have pushed this completion date back to 2027: new presidents, pandemics, recessions, catastrophic weather events, and countless smaller factors.

For a glimpse at how things stood in April 2015, subscribers to the Industrial Info Resources Global Market Intelligence (GMI) Oil & Gas Project Database can take a look at the original project report. For the latest information, subscribers can look at the most recent reports for Train 1 and Train 2, both released in March 2026.

By the Numbers

• More than $26 billion: Projected investment across various phases of Port Arthur LNG
• 2027: The expected in-service date for Train 1
• More than 9 million metric tons: Total capacity of offtake agreements in place for the first two trains

Location, Location, Location--and Offtake

It is unlikely Port Arthur LNG would have received so much support had it not been so strategically located. Its position in Jefferson County, Texas, gives it access to major natural gas resources such as the Barnett, Eagle Ford and Haynesville shale plays. It also provides direct access to the Gulf Coast, via the Sabine-Neches ship channel.

Port Arthur LNG will receive its feedstock from two major pipeline systems, the Louisiana Connector Pipeline and the Texas Connector Pipeline, both of which will link up to various intrastate and interstate pipelines, themselves connected to a variety of major U.S. natural gas supply basins.

The Louisiana Connector started construction last year, and the Texas Connector is set to begin construction later this year. Detailed information on these two pipeline systems can be found from a detailed list of project reports for the Louisiana Connector and the Texas Connector.

But just as crucial to the project's location is its offtake agreements. No sensible developer would approve expenditures on such a massive project if it did not have buyers already locked in. Those who have agreed to buy product from the first two trains include:

• ConocoPhillips, at 5 million metric tons per year
• INEOS Energy Trading, at 1.4 million metric tons per year
• Polskie Górnictwo Naftowe i Gazownictwo (PGNiG), which is Poland's largest oil and gas company, at 1 million metric tons per year
• PKN Orlen, at 1 million metric tons per year
• ENGIE S.A., at 875,000 metric tons per year

Key Takeaways

• The Port Arthur LNG project has been in some phase of development since early 2015.
• Two major pipeline systems will provide feedstock from a variety of natural gas basins to the complex.
• Numerous companies, both U.S. and European, have agreed to buy offtake from Port Arthur LNG.
