Project Status
The Port Arthur Pipeline Louisiana Connector project has been placed in-service. It will support the safe, reliable transportation of 2 billion cubic feet per day (Bcfd) of U.S. natural gas to global markets by supplying gas to Port Arthur LNG Phase 1, which have nameplate capacity of approximately 13 million tonnes per annum (Mtpa) and is currently under construction.
Additionally, the pipeline strengthens domestic energy networks by interconnecting with Sempra Infrastructure’s Gillis Hub Pipeline, a highly connected natural gas pipeline header system in Southwest Louisiana’s energy corridor. Importantly, the pipeline also connects to Sempra Infrastructure’s LA Storage facility that is currently under construction to facilitate transportation to and from critical natural gas storage capacity along the U.S. Gulf Coast.
