The Federal Energy Regulatory Commission (FERC) recently approved the addition of two new salt caverns at a nearly 15-year-old storage site in Jefferson County.

On July 23, 2024, FERC issued an authorization for an expansion at the Golden Triangle Storage Facility, which began operating in 2010 and receives gas for storage from nearby large pipelines. The proposed project would consist of the addition of two new salt dome storage caverns, one brine well, and six new 5,500 horsepower engines to the existing on-site compressor.

The project is one of three gas storage projects planned in Mississippi and Texas hat would together add about 58 billion cubic feet of underground natural gas storage capacity, or about 8 percent more than the amount currently stored this way in the U.S. Companies are proposing to expand the facilities to supply a rapidly growing gas industry and to use gas generators to back up the use of wind and solar power.
