Liquefied Natural Gas Unit
Rio Grande LNG seeks bigger Texas terminal expansion
Rio Grande LNG Train 6 wants to add another liquefied natural gas unit and a new dock at its Cameron County terminal, lifting ship traffic to 510 vessels a year. Federal regulators are taking comments through June 30.
Rio Grande LNG Train 6, LLC is asking federal regulators to approve another expansion at its Cameron County terminal. The project would add about 6.03 million tonnes a year of LNG capacity and increase authorized ship traffic.
- Would add about 6.03 million tonnes a year of LNG capacity
- Would raise authorized LNG carrier traffic to 510 vessels annually
- Covers a new liquefaction train, marine jetty and related facilities
- The terminal is already under construction in Cameron County
- Rio Grande LNG Train 6, LLC is asking federal regulators for permission to add another liquefaction train and a new marine jetty at its existing terminal in Cameron County, Texas
Rio Grande LNG Train 6, LLC is asking federal regulators for permission to add another liquefaction train and a new marine jetty at its existing terminal in Cameron County, Texas. If the request is approved, the expansion would add about 6.03 million tonnes per annum of LNG production capacity and raise authorized LNG carrier traffic to 510 vessels a year.
The project builds on a terminal that was previously approved and is already under construction, which gives the new filing real-world weight for nearby communities and for the industrial traffic that moves through the Texas coast. For Cameron County, the question is not just how much more gas can move out, but how much more activity the shoreline can absorb.
More gas, more marine traffic
The application was filed under section 3(a) of the Natural Gas Act and Part 153 of the Federal Energy Regulatory Commission’s rules. It covers the Rio Grande LNG Expansion Project at the existing terminal and calls for one additional liquefaction train, one new marine jetty and associated facilities.
That means more export capacity, more ship calls and a larger industrial footprint around an operation that is already on the ground. For terminal workers, contractors, port users and nearby residents, the change would be felt in the scale of the project itself, not just in the paperwork behind it.
A bigger footprint on the coast
The notice also makes the application available for public inspection inside FERC’s process, giving interested parties a way to engage with the proposal while it is under review. The practical issue is straightforward: this is a request to grow an already approved Gulf Coast export terminal into something larger, busier and harder to miss.
In energy terms, the filing shows how quickly an LNG project can keep adding layers after the first approval. In coastal terms, it means another round of decisions about industrial land use, vessel traffic and the space a single terminal can take up along the water.
