Rio Grande LNG adds $6M in new buildings at Port of Brownsville 

Rio Grande LNG has filed plans for six new support buildings worth $6 million at its export terminal at the Port of Brownsville, adding security, laboratory, emergency response and operational facilities as construction continues on one of the Rio Grande Valley’s largest private investments.

The projects were registered Wednesday with the Texas Department of Licensing and Regulation for the Rio Grande LNG facility at 48326 State Highway 48. Construction on each building is scheduled to begin July 30 and conclude by Dec. 1.

Combined, the projects represent 20,191 square feet of new construction and include several buildings that will support operations at the liquefied natural gas export terminal.

The largest filing is a $2 million, 4,876-square-foot security building.

Five additional projects were also registered:

• Two 354-square-foot comfort station buildings, each valued at $500,000.
• A 3,455-square-foot fire truck building valued at $1 million.
• A 6,936-square-foot chemical storage building valued at $1 million. According to the filing, the building is designed for forklift access and will not include regular personnel foot traffic.
• A 4,216-square-foot laboratory building valued at $1 million.

All six projects are privately funded by Rio Grande LNG LLC, according to the filings. Houston-based Burrow Global is listed as the design firm for each building.

The filings add another series of support buildings to the multibillion-dollar LNG export terminal under construction at the Port of Brownsville. 

The project has emerged as one of the largest private investments in the Rio Grande Valley, bringing thousands of construction jobs and new industrial activity to the port.

Rio Grande LNG reached a final investment decision on its first phase in 2024 and is developing the export terminal with three liquefaction trains capable of producing approximately 18 million metric tons of liquefied natural gas annually. 

The company has also advanced plans for additional expansion phases that would further increase the terminal’s export capacity.
