Sempra Launches Permitting for Major Texas LNG Expansion

Sempra Energy has initiated the federal permitting process for a major expansion of its liquefied natural gas (LNG) export operations in Southeast Texas. The proposed Port Arthur LNG North Project aims to add four liquefaction trains, each capable of producing up to 6.73 million metric tons per annum (mtpa) of LNG under optimal conditions. This expansion would significantly boost Sempra’s export capacity, with the project including three LNG storage tanks and marine facilities featuring up to two LNG berths for loading cargoes.

The project, if approved and constructed, could commence LNG exports in the second half of 2034. Sempra already has Port Arthur Phase 1 and Phase 2 under development, with a combined capacity of 26 mtpa. The proposed north project would further solidify Southeast Texas as a leading global LNG export hub.

This move aligns with the broader trend of U.S. developers expanding LNG export capabilities to meet rising global demand. The United States is currently the world’s largest LNG exporter, and numerous expansion projects have been proposed along the Gulf Coast in recent years. Sempra did not disclose the estimated cost of the project in its regulatory filing.
