The Cameron LNG Amended Expansion Project by Sempra is a planned expansion of the Cameron LNG export terminal near Hackberry, Louisiana. The project is intended to increase the facility’s LNG production capacity through the addition of a fourth liquefaction train and modifications to the existing facility.
The U.S. Federal Energy Regulatory Commission (FERC) granted a five-year extension to Sempra Infrastructure’s Cameron LNG expansion, moving the completion deadline to March 16, 2033. The extension followed a request from Cameron LNG for additional time to advance construction and complete the project. FERC continued to list the Cameron LNG Amended Expansion Project among its environmental documents, under docket CP22-41-000.
The Cameron LNG facility is located near Hackberry in southwest Louisiana and operated three liquefaction trains with a combined export capacity of approximately 14.95 million tonnes per annum (Mtpa). The approved amended expansion proposed a fourth train with a production capacity of 6.75 Mtpa, replacing an earlier proposal for two smaller trains.
The proposed Train 4 is designed to use electric-drive motors instead of gas turbines. The expansion design also included tie-in facilities that would allow for potential carbon dioxide sequestration. The project was planned to be constructed on property already owned and managed by Cameron LNG.
The extension provided additional time for Sempra and its joint-venture partners to progress the expansion under the revised schedule. The project remained in the development and permitting process rather than being listed as an operational expansion. Cameron LNG continued to describe the amended project as providing up to 6.75 Mtpa of additional LNG production capacity.
Louisiana is also home to other LNG developments, including Woodside’s $17.5 billion Plaquemines LNG terminal near Belle Chasse.
The Cameron LNG terminal formed part of the U.S. LNG export infrastructure, while the amended expansion remains subject to its extended development schedule and regulatory requirements.

Other Projects
Another major LNG project making headway is the Plaquemines LNG. The project is currently pursuing an $18 billion expansion that would make it North America’s largest liquefied natural gas export terminal under the Trump administration’s expedited “national energy emergency” permitting process. The facility is to be expanded from almost 590 acres to about 1,220 acres along the Mississippi River, more than doubling its size. The Plaquemines LNG expansion was approved by the Army Corps of Engineers in a matter of 10 days, instead of the usual 30-day public comment period. In the meantime, environmentalists say the expedited review could endanger up to 470 acres of wetlands and river bottoms in Central Plaquemines Parish in Louisiana.
