About Port Arthur LNG
Port Arthur LNG represents a $27 billion investment in new energy infrastructure in Texas that will stimulate local, regional and national economies by creating U.S. jobs, supporting small businesses and strengthening the U.S. natural gas sector’s leadership position as a reliable partner in building energy security worldwide.
The natural gas liquefaction and export terminal in Jefferson County, Texas is strategically located with access to abundant natural gas resources and direct access to the U.S. Gulf Coast via the Sabine-Neches ship channel. The Port Arthur LNG facility through Phases 1 and 2 is designed to include four natural gas liquefaction trains, three liquified natural gas (LNG) storage tanks and associated facilities with a nameplate capacity of approximately 26 million tonnes per annum (Mtpa).
Port Arthur LNG Phase 1, which is currently under construction, is a joint venture project between Sempra Infrastructure and ConocoPhillips and has long term definitive offtake agreements with ConocoPhillips, RWE, Orlen, INEOS and Engie
The expected operation dates for Train 1 and Train 2 are 2027 and 2028, respectively.
Phase 2, which announced a final investment decision in September 2025, is jointly owned by Sempra Infrastructure and an investor consortium led by Blackstone Credit & Insurance, together with KKR, Apollo-managed funds and Private Credit at Goldman Sachs Alternatives. Phase 2 is subscribed with long-term offtake sales and purchase agreements with strategic partner ConocoPhillips as an anchor, and high-quality counterparties EQT, JERA, and Sempra Infrastructure Partners.
The expected commercial operation dates for Train 3 and Train 4 are 2030 and 2031, respectively.
Construction
Construction for Phase 1 began shortly after a positive final investment decision was reached in March 2023. Sempra Infrastructure contracted with global engineering, procurement and construction firm Bechtel Energy Inc. Bechtel has also received full notice to proceed for Phase 2 of the project. Bechtel’s continued involvement from Phase 1 into Phase 2 is expected to drive favorable economics and help mitigate execution risk by leveraging efficiencies and learnings across phases.
Phase 1 is expected to create 6,000 construction jobs at peak construction, and Phase 2 will add another 2,000 construction jobs.
