Sempra Brings 72-Mile, Sub-$1B Gas Pipeline Online to Power LNG Exports
SRE•Sempra Infrastructure has placed into service the 72-mile, 42-inch Port Arthur Louisiana Connector pipeline, delivering 2 Bcf/d to the under-construction Port Arthur LNG Phase 1 export facility. Completed ahead of schedule at under $1 billion, the pipeline links Sempra’s Gillis Hub and planned Louisiana Storage for Gulf Coast network flexibility.
1. Pipeline Completion and Service Start
Sempra Infrastructure has completed and placed into service the Port Arthur Pipeline Louisiana Connector, a critical 72-mile, 42-inch natural gas line designed to feed the Port Arthur LNG Phase 1 export terminal in Texas. The pipeline achieved initial operations on schedule, marking a major milestone for the project.
2. Technical Specifications and Cost Efficiency
The connector transports up to 2 billion cubic feet per day and includes a new compressor station in Beauregard Parish. Total capital expenditures remained below $1 billion, representing cost savings from efficient project management and execution ahead of the projected timeline.
3. Network Integration and Flexibility
Linking directly to Sempra’s Gillis Hub Pipeline system in southwest Louisiana, the new line enhances gas delivery flexibility across the Gulf Coast. It also connects to the under-construction Louisiana Storage project, providing additional storage and transport options for regional markets.
4. Strategic Impact on LNG Exports
The pipeline strengthens the infrastructure supporting Port Arthur LNG Phase 1, which targets approximately 13 million metric tons per year of export capacity. By bolstering export capabilities, Sempra is positioned to meet growing global LNG demand in Europe and Asia while advancing its North American infrastructure strategy.
