August 28, 2025 [Storage Terminals Magazine]- Sempra Infrastructure, a subsidiary of Sempra, and EQT Corporation have announced a 20-year definitive sales and purchase agreement for the supply of 2 million tonnes per annum of liquefied natural gas from the Port Arthur LNG Phase 2 development project in Jefferson County, Texas. Under the terms of the SPA, EQT will acquire the LNG on a free-on-board basis at a price indexed to Henry Hub.
“Advancing the Port Arthur LNG Phase 2 project with EQT underscores our shared commitment to ensuring that US natural gas projects support local economic development while providing global markets with a stable, long-term supply of LNG,” said Justin Bird, CEO of Sempra Infrastructure. He added that this project could bolster America’s position as a leading energy exporter, aligning with the objectives of both EQT and Sempra Infrastructure.
Toby Z. Rice, president and CEO of EQT, highlighted that the agreement emphasises EQT’s role in promoting US LNG as a means to enhance global energy security and advance lower-carbon solutions. “We are proud to partner with Sempra Infrastructure on this vital project, furthering the pursuit of American energy dominance,” he stated.
The Port Arthur LNG Phase 2 development project is strategically located to help meet global energy demand and has garnered significant interest from potential LNG buyers. In July 2025, Sempra Infrastructure signed a definitive 20-year SPA with JERA Co., Inc. for 1.5 Mtpa of LNG offtake. Earlier this month, the company expanded its strategic alliance with ConocoPhillips through a 20-year SPA for 4 Mtpa of LNG offtake from the proposed project. Future phases of development are also underway.
In September 2023, the Federal Energy Regulatory Commission granted approval for the project, followed by an export authorisation from the US Department of Energy in May 2025, allowing LNG exports to countries without a free-trade agreement with the United States. All major permits for the Port Arthur LNG Phase 2 development project have been secured.
Sempra Infrastructure has also announced that Bechtel has been chosen to handle the engineering, procurement, and construction of the Port Arthur LNG Phase 2 facility. As the project continues to gain momentum, Sempra Infrastructure aims to make a final investment decision on the Port Arthur LNG Phase 2 project in 2025.
Port Arthur LNG Phase 2 is anticipated to feature two liquefaction trains with a combined production capacity of approximately 13 Mtpa of LNG, potentially increasing the total liquefaction capacity of the Port Arthur LNG facility from around 13 Mtpa for Phase 1 to approximately 26 Mtpa. Port Arthur LNG Phase 1 is currently under construction and is expected to commence commercial operations in 2027 and 2028 for trains 1 and 2, respectively.
The development of the Port Arthur LNG Phase 2 project is subject to various risks and uncertainties, including the completion of required commercial agreements, securing and maintaining necessary permits, obtaining financing, and reaching a final investment decision, among other factors.
