Location : Jefferson and Orange Counties, Texas and Cameron Parish, Louisiana
Capacity : 2.0 Bcfd
Size : 34.2 miles, 42-inch diameter pipeline
Projected Commercial Operation : 2023

Port Arthur Pipeline, LLC, a subsidiary of Sempra LNG, is proposing to develop a natural gas pipeline in connection with the proposed development of the Port Arthur Liquefaction Project by Port Arthur LNG, LLC, and PALNG Common Facilities in Jefferson County, Texas. The proposed Port Arthur Pipeline Project – Texas Connector (PAPTC) would consist of two segments oriented north and south of the proposed liquefaction project.

The 27.6-mile northern portion of the proposed PAPTC project would extend from Vidor in Orange County, TX to the proposed liquefaction project, with the majority of the proposed pipeline co-located with existing energy infrastructure rights-of-way. The approximately seven-mile southern portion of the proposed Pipeline Project would originate in Cameron Parish, Louisiana on the east bank of Sabine Lake and terminate at the Port Arthur Liquefaction Project.

The proposed PAPTC project would interconnect the Port Arthur Liquefaction Project to various intra- and interstate pipelines, providing access to a number of major U.S. natural gas supply basins.

The following facilities will be constructed as part of the Pipeline Project:

      • A total of approximately 34.2 miles of 42-inch-diameter pipeline
      • Two compressor stations
      • New interconnections with intra- and interstate pipelines

        Proposed Project Schedule

        Project development and Front End Engineering Design (FEED) activities began in 2014. In March 2015, the project initiated pre-filing review with the Federal Energy Regulatory Commission (FERC).

        The project received authorization from FERC April 2019. Construction is expected to begin in the 2021, with commercial operations expected to begin in 2022.

        Development of the Port Arthur Liquefaction Project and the Pipeline Project – Texas Connector is contingent upon completing the required commercial agreements, securing all necessary permits and approvals, obtaining financing and incentives, achieving other customary conditions, reaching a final investment decision and other factors associated with the investments.


      • Pipeline infrastructure provides a reliable solution for the delivery of natural gas to the proposed Port Arthur Liquefaction Project
      • Expected to create about 686 new design, engineering and construction jobs, as well as 20 long-term positions to operate and maintain the proposed pipeline facilities
      • Provides a new source of revenue for local providers of goods and services
      • Project Contacts
