FERC announced the decision on Monday.
Cameron LNG is jointly owned by affiliates of Sempra Infrastructure, TotalEnergies, Mitsui & Co., and Japan LNG Investment, a joint venture between Mitsubishi Corporation and NYK.
The terminal currently includes three liquefaction trains capable of exporting up to 14.95 million tonnes per annum (mtpa), or approximately 772 billion cubic feet of natural gas per year.
In addition to these three trains, Sempra and its partners are working to expand the facility with the fourth train, with a capacity of about 6.75 mtpa.
In 2023, Sempra Infrastructure and its partners received approval from FERC for their revised expansion project, as they previously planned to build two additional LNG units, adding about 10 mtpa.
Last month, Cameron LNG requested a 60-month extension, until March 16, 2033, to construct and place the amended expansion project into service.
Cameron LNG said that it has “diligently worked” to advance the project by working with the
Louisiana Department of Environmental Quality (LDEQ) to issue the modification to its existing air permit and by continuing to maintain all other required permits.
The LNG terminal operator claims it has also made “significant” engineering and commercial efforts to advance the project such as various design enhancements to increase efficiency and reliability of the project.
Also, Cameron LNG said that the project’s lenders require assurances that it has all necessary authorizations, including the approval of this extension of time request prior to reaching a positive financial decision for the amended expansion project facilities.
“Good faith effect”
On October 28, 2025, FERC issued a public notice of Cameron LNG’s request for an extension of time, with interventions, comments, and protests due November 12, 2025.
FERC said that Restore Explicit Symmetry To Our Ravaged Earth (RESTORE) filed a comment indicating that it is against the approval of the extension of time request, citing numerous violations of Cameron LNG’s existing LDEQ air quality permit and a request for a delay in the processing of its modification to the permit for the project facilities.
No other comments, protests, or interventions were filed.
According to FERC, RESTORE’s comments regarding Cameron LNG’s air permit violations are
outside the scope of Cameron LNG’s request for an extension of time.
“Cameron LNG has demonstrated its continued commitment to the project and made a good faith effect to meet its in-service deadline,” FERC said.
“Based on the facts presented in the request and the case record, Cameron is granted an extension of time until and including March 16, 2033 to complete construction of its amended expansion project facilities and make them available for service,” the regulator concluded.
