Sempra Infrastructure placed the Port Arthur Pipeline Louisiana Connector into service on June 9, 2026. The 72-mile, 42-inch pipeline transports up to 2 billion cubic feet of natural gas per day. This infrastructure serves the Port Arthur LNG Phase 1 export terminal.
The project reached completion ahead of schedule and under its nearly $1 billion budget. It provides critical support for the commissioning and operation of the new LNG facility.
The pipeline enhances transportation and storage capabilities along the U.S. Gulf Coast. This development expands America's capacity to export liquefied natural gas to global markets.
