North American energy supplier Sempra Infrastructure has locked in a 15-year deal with French utility Engie for liquefied natural gas supply to be sourced from the Port Arthur LNG project.

US-headquartered Sempra will source the gas to supply Engie from phase one of the Port Arthur facility on the Texas US Gulf Coast, which is due to come online in 2027.

The contract covers 875,000 tonnes per annum of LNG delivered as free on board, and sourced from third-party suppliers with certified environmental, social and governance (ESG) performance standards, Sempra said.
