Emerald Storage Holdings LLC, the parent company of Enstor Gas LLC and Mississippi Hub LLC, has received Federal Energy Regulatory Commission (FERC) permission to proceed with construction of its Mississippi Hub Expansion Project. The project will more than double the site’s capacity, to roughly 56.3 bcf.
Mississippi Hub is a high-deliverability underground natural gas storage site on the Bond Salt Dome in Simpson County, Miss. The expansion will add three 10-bcf storage caverns and incrementally expand the hub’s existing caverns, for a total of as much as 33.5 bcf of new working storage and 700 MMcfd of new injection capacity. Injection capacity will increase to a total of 1.9 bcfd, while withdrawal capacity will remain at 2.4 bcfd, as previously certificated before the expansion.
Enstor plans to begin construction immediately and anticipates the expansion to be in-service by 2028.

OD pipeline runs from an interconnect with two existing TC Energy pipelines in Fulton County, Pa., through Washington County, Md., to a delivery point with local distribution company Mountaineer Gas Co. in Morgan County, WV.
