NextDecade Rio Grand expansion plan — NextDecade Corp. has initiated the pre-filing process with the Federal Energy Regulatory Commission for expansion at Rio Grande LNG that includes a sixth liquefaction train and an additional marine berth.

NextDecade Corp. has initiated the pre-filing process with the Federal Energy Regulatory Commission (FERC) for expansion at Rio Grande LNG that includes a sixth liquefaction train (Train 6) and an additional marine berth.

The company expects to file a full application for the expansion with FERC in 2026.

Trains 1-5 are under construction on the north shore of the Brownsville Ship Channel in south Texas, and NextDecade is developing and advancing the permitting process for Trains 6-8.

Train 6 is being developed inside the existing levee at the Rio Grande LNG plant site and adjacent to Trains 1-5.

The company is evaluating areas on the site for development of Trains 7 and 8, which would bring potential liquefaction capacity at the plant to about 48 million tonnes/year.

NextDecade says the site has sufficient space for development of up to 10 liquefaction trains.
