Calcasieu Pass LNG is a ten million tonnes per annum (mtpa) LNG export terminal to be developed by Venture Global Calcasieu Pass, a subsidiary of Venture Global LNG, in Louisiana, US.
The $4.5bn project received final approval from the US Federal Energy Regulatory Commission (FERC) in February 2025.
Construction on the project is expected to be started upon making the final investment decision (FID) in the first half of 2025.
The LNG export facility is scheduled to commence operation in 2022 and will have an operational life of 25 years.
Calcasieu Pass LNG export terminal location
The export facility will be built on a 930-acre site in Cameron Parish, towards the southern edge of the city of Lake Charles in Louisiana, on the intersection between the Calcasieu Ship Channel and the Gulf of Mexico.
Calcasieu Pass export terminal details
The Calcasieu Pass LNG export facility is planned to be developed with nine liquefaction blocks of 1.2Mtpa capacity each, along with two 200,000m3 LNG storage tanks.
The construction of the LNG facility will follow modular approach and each liquefaction block at the facility will accommodate two LNG trains of 0.626Mtpa capacity.
The liquefaction blocks will receive power supply from a 720MW onsite natural gas-fired combined-cycle gas-turbine (CCGT) power plant.
The Calcasieu Pass LNG project also includes a marine terminal on the western side of the liquefaction facility. The marine terminal can accommodate LNG carriers with capacity up to 185,000m³. It will have two loading platforms supported by eight breasting dolphins, 12 mooring dolphins, and six intermediate walkway supports.
Gas supply
The Calcasieu Pass LNG export project will be integrated with Venture Global LNG’s proposed TransCameron pipeline to source feed gas.
The 38km-long and 42in-dimeter TransCameron Pipeline will be interconnected with TETCO’s existing East Lateral pipeline near Grand Chenier, Louisiana, US.
The TransCameron pipeline will be designed to deliver 1.9 billion cubic feet (bcf) of gas a day.
LNG off-take from Calcasieu Pass LNG export facility
Polish Oil & Gas Company (PGNiG) entered a 20-year gas sales and purchase agreement with Venture Global LNG for the supply of 2Mtpa of LNG from the export terminal, in June 2018.
Another 20-year agreement was signed with Edison for the delivery of 1Mtpa of LNG, in September 2017.
Calcasieu Pass terminal will also deliver LNG to BP Gas Marketing (2Mtpa), Shell NA LNG (2Mtpa), Galp (1Mtpa), and Respol (1Mtpa) for a period of 20 years.
The Calcasieu Pass LNG terminal received approval from the US Department of Energy (DOE) to ship LNG to non-free trade agreement (FTA) countries including Australia, Canada, Israel, Jordan, Korea, Mexico, Oman, Panama, and Singapore, in March 2025.
Contractors involved
Kiewet was awarded the engineering, procurement, and construction (EPC) contract for the Calcasieu Pass export facility, in December 2018.
GE Oil and Gas, a subsidiary of Baker Hughes (a GE company), was selected to provide mid-scale, modular, factory-fabricated liquefaction trains for the Calcasieu Pass LNG facility, in February 2017.
CB&I (now McDermott) was awarded a $200m EPC contract for the two LNG storage tanks of the facility, in July 2017.
Providence Engineering, along with Duplantis Design Group, was involved in the permitting process and design for the 130-acre marsh area for the construction of the LNG terminal and pipeline.
