Background
Sempra is a US Energy infrastructure company headquartered in San Diego, California. Through its subsidiary Sempra Infrastructure, it operates Cameron LNG at Hackberry, Louisiana (three trains, ~12 mtpa) and is developing Port Arthur LNG in Texas — one of the largest US LNG export projects under construction. Long-term sales and purchase agreements link Cameron and Port Arthur output to major European buyers including TotalEnergies, RWE and Mitsui.
Sempra's EU-bound cargoes are part of the structural 45% year-on-year rise in US LNG deliveries to Europe recorded by ACER, with the US now supplying 30% of EU gas imports. Cameron LNG has been operating at high utilisation since 2022 as European buyers activated long-term offtake agreements following Russia's invasion of Ukraine.
Port Arthur LNG, once fully operational, will ADD materially to US LNG export capacity; its long-term contracts with European utilities represent a multi-decade supply commitment that extends well beyond current geopolitical drivers. Sempra positions itself as a reliable, contracted counterparty to European energy security strategy.
