The Cameron LNG terminal, which is located in Cameron Parish, Louisiana, will now export LNG up to equivalent of 1.7 billion standard cubic feet per day (Bcf/d) of natural gas for a period of 20 years.

Up to the equivalent of 0.04 Bcf/d of natural gas will be exported by Carib from the proposed liquefaction facility in Martin County, Florida, using approved ISO LNG containers, for a period of 20 years.

Sempra Energy chairman and CEO Debra Reed said: "This landmark project will create thousands of jobs and economic benefits for Louisiana and the U.S. for decades to come, while delivering natural gas to America’s trading partners in Europe and Asia."

Sempra LNG president Octavio Simoes said: "With this final authorization from DOE and the previous permit granted by FERC, we will be able to remain on schedule and commence operations during 2018."
