Commonwealth LNG, a liquefaction and export facility in Cameron Parish, Louisiana, has entered into a 20-year sale and purchase agreement (SPA) with Aramco Trading, a subsidiary of Saudi Arabia's Aramco. The agreement involves the purchase of 1 million tonnes per annum (mtpa) of liquefied natural gas (LNG) from the Commonwealth LNG project.

Why it matters

This deal highlights the strong international demand for US LNG and underscores Commonwealth LNG's ability to serve global markets through its global reach and capabilities. The project is moving closer to a final investment decision as it secures more long-term offtake contracts with international energy companies.

The details

Commonwealth LNG is a 9.5mtpa liquefaction and export facility being developed on the western side of the Calcasieu Ship Channel in Cameron Parish, Louisiana. The facility will feature five storage tanks, each with a capacity of 50,000m³, and will be capable of receiving vessels as large as 216,000m³. The gas supply will come through a newly built 4.8km-long pipeline that connects to two major pipeline networks. Technip Energies has been engaged to provide engineering, procurement and construction services for the development, using its SnapLNG by T.EN modular, scalable solution.

  • Commonwealth LNG is aiming to secure the rest of its capacity and reach a final investment decision (FID).
  • The first phase of Commonwealth LNG's development is projected to generate approximately $3.5 billion in annual export revenue.
  • The project is expected to be operational by 2030.
