More Jobs and Economic Benefits

Train 4 Project Overview

With demand for LNG worldwide continuing to grow, Freeport LNG is developing a fourth natural gas liquefaction unit in addition to the three trains already under construction. This expansion will allow for the export of an additional 5 mtpa of LNG, increasing the project’s total export capability to some 20 mtpa of LNG per year. Train 4 will create thousands of additional jobs and result in billions of dollars in economic benefits for the U.S.

It will require approvals from a number of regulatory agencies including the Federal Energy Regulatory Commission (FERC), the lead regulatory agency responsible for permitting LNG facilities, and the U.S. Department of Energy (DOE), the agency responsible for authorizing exports of LNG. Additional approvals will be required from the Texas Commission on Environmental Quality along with several other federal, state and local agencies.

In June 2017, Freeport LNG submitted a formal application with FERC for authorization to site, construct and operate Train 4, and at the same time commenced the front-end engineering and design (FEED) for the additional facility. Information about the FERC docket for the Train 4 project can be found directly at or by going to and entering Docket Number CP17-470 in the FERC eLibrary search form.

Like the first three trains, Train 4 will use electric motors with variable frequency drive for the cooling and liquefaction compression power, resulting in negligible incremental emissions. Train 4 will be constructed adjacent to the first three trains on Quintana Island.
