Home Energy Company News By Charles Kennedy - Sep 14, 2026, 7:33 PM CDT Sempra Infrastructure has secured another long-term buyer for its expanding U.S. LNG portfolio, signing a 20-year sales and purchase agreement with Brazil’s Petrobras for approximately 800,000 tonnes per year of liquefied natural gas. The LNG will come from Sempra Infrastructure’s contracted liquefaction capacity at the Port Arthur LNG Phase 2 project in Jefferson County, Texas, according to the company.
Petrobras will become the first South American company in Sempra Infrastructure’s LNG customer portfolio. The agreement gives Petrobras access to long-term U.S. gas supply while adding another major international buyer to Sempra’s Port Arthur development, which is emerging as one of the larger LNG export expansions under construction on the U.S. Gulf Coast.
Port Arthur Phase 2 reached a final investment decision in September 2025 and is designed to add roughly 13 million tonnes per annum of liquefaction capacity through two additional trains. Sempra estimated project capital spending at around $12 billion, plus approximately $2 billion for shared facilities with Phase 1. Trains 3 and 4 are expected to enter commercial service in 2030 and 2031, respectively.
Once both phases are operational, the Port Arthur complex could have approximately 26 million tonnes per year of LNG production capacity. Phase 1, also around 13 Mtpa, is already under construction, with its two trains targeted to start commercial operations in 2027 and 2028. Sempra lined up several major customers for Phase 2 ahead of its investment decision.
ConocoPhillips signed a 20-year agreement covering 4 Mtpa in August 2025, while Japan’s JERA had previously contracted 1.5 Mtpa. EQT also signed a 20-year agreement covering 2 Mtpa later that month. The Petrobras deal extends the project’s commercial reach into South America and underscores continued demand for long-duration U.S.
LNG contracts even as a substantial wave of new American export capacity moves toward commissioning over the next several years. Port Arthur Phase 2 already holds federal authorization to export LNG to both free-trade and non-free-trade agreement countries, removing a key regulatory hurdle for sales into global markets.
