What is the significance of Sempra's Costa Azul LNG export plant in Mexico's energy infrastructure?

The Costa Azul export plant — known as ECA LNG — is Mexico’s first West Coast LNG export terminal and marks a strategic shift from its original purpose as an import facility for Indonesian LNG to southern California; it now exports U.S.-sourced natural gas to Asia, making it a key new node in North America’s growing LNG export network.

Who are the contracted off-takers for the ECA LNG terminal, and what is their combined annual purchase commitment?

The terminal has supply contracts with Sempra’s joint venture partner TotalEnergies SE and Japanese trading firm Mitsui & Co. Ltd, for a combined 2.5 million metric tons of LNG per year.
