Cheniere’s Corpus Christi plant currently liquefies natural gas at three operational trains, each with a capacity of about 5 mtpa.
In June 2022, Cheniere made the final investment decision on the Corpus Christi Stage 3 expansion project, worth about $8 billion, while compatriot Bechtel officially started construction on the project in October of the same year.
The project includes building seven midscale trains, each with an expected liquefaction capacity of about 1.49 mtpa.
In March 2025, Cheniere achieved substantial completion of the first liquefaction train at the Corpus Christi Stage 3 expansion project, while the company completed the second liquefaction train in August.
Construction update
Cheniere’s unit, Corpus Christi Liquefaction, said in the August construction report filed with the US FERC on Tuesday that the overall project completion rate for Stage 3 is 89.3 percent.
The project was 87.9 percent complete as of the end of July.
Stage 3 engineering and procurement were 99.4 percent and 100 percent complete as of the end of August 2025, respectively, while subcontract and direct hire construction work were 93 percent and 71.6 percent complete, respectively.
During August, key work fronts included aboveground piping in Train 3 – 7 and outside boundary limits (OSBL), concrete pours in Trains 4 – 7 and OSBL, structural steel erection in Trains 4 – 7 and OSBL, underground piping installation in Trains 6 – 7 and OSBL, and equipment setting in Trains 4 – 7.
CCL said additional continued work included road improvements, drainage work, and mobilization of temporary facilities, equipment, and personnel.
Key work fronts for the Midscale Trains 8 & 9 project included site preparation activities and construction of the sixth BOG compressor, the company noted.
During September, Bechtel will continue installation and testing of aboveground piping, insulation of aboveground piping, and cable pulls at the third liquefaction train.
Cheniere is nearing the completion of this train.
FERC recently granted CCL’s request to introduce feed gas and refrigerants to the cold end of the midscale Train 3 – string 1, and hydrocarbons to the Train 3 condensate system.
Additionally, Cheniere initiated commissioning activities at the fourth train of the Corpus Christi Stage 3 expansion project.
Cheniere expects substantial completion of Train 3 and first LNG from Train 4 before the year-end of 2025.
Further expansion
Cheniere made a positive final investment decision to build two more midscale trains at its Corpus Christi LNG plant in June this year.
The CCL midscale trains 8 and 9 project is being built adjacent to the Corpus Christi Stage 3 project and consists of two midscale trains with an expected total liquefaction capacity of over 3 mtpa of LNG and other debottlenecking infrastructure.
Upon completion of the project, and together with expected debottlenecking and CCL Stage 3, the Corpus Christi LNG terminal is expected to reach over 30 mtpa in total liquefaction capacity later this decade, according to Cheniere.
In addition, Cheniere received approval from the US FERC to initiate the environmental pre-filing review for its Corpus Christi Liquefaction Stage 4 project.
The trains will have a peak production capacity of approximately 24 mtpa of LNG.
