Williams announced that it has entered into a non-binding heads of agreement (HOA) with Sempra Infrastructure that establishes the elements of an integrated platform to further connect the prolific Haynesville basin to growing LNG export demand along the Gulf Coast and around the world. The HOA contemplates long-term gas sales of approximately 0.5 billion cubic feet per day (Bcf/d) delivered near Gillis, Louisiana, and two LNG offtake agreements for approximately 3 million tons per annum (mtpa) in the aggregate from Sempra Infrastructure's proposed Cameron LNG Phase 2 and Port Arthur LNG projects. These proposed transactions complement Williams' recently sanctioned low-carbon Louisiana Energy Gateway (LEG) gathering project and are expected to include connections to pipelines serving Sempra Infrastructure's LNG export facilities.

As part of the proposed transaction, Williams and Sempra Infrastructure plan to form a strategic joint venture to own, expand and operate the Cameron Interstate Pipeline that is expected to deliver natural gas to the proposed Cameron LNG Phase 2 in Hackberry, Louisiana. Additional pipelines are also expected to be owned by the joint venture, including the Louisiana Connector Pipeline expected to deliver natural gas to Sempra Infrastructure's proposed Port Arthur LNG facility, located in Port Arthur, Texas. Williams' LEG project, which is expected to go into service in late 2024, will gather 1.8 Bcf/d of natural gas produced in the Haynesville basin.

Williams, through partnerships with Context Labs, Encino Environmental and Satlantis, is integrating technology solutions into the project to enable the measurement of end-to-end, verifiable and transparent emissions data to demonstrate the low carbon benefits of produced and delivered Haynesville natural gas. Williams is also exploring the enhancement of the LEG project with the addition of carbon capture and storage infrastructure that will further decarbonize the natural gas value chain.
