Enstor Announces Receipt and Acceptance of FERC Certificate to Significantly Expand Its Mississippi Hub Natural Gas Storage Facility
Enstor Gas has received FERC approval for its Mississippi Hub Expansion Project, with construction set to begin after reaching final investment decision (FID). The project will expand the underground natural gas storage facility in Simpson County, Mississippi by adding three storage caverns with 10 Bcf capacity each.
The expansion will increase total working gas storage capacity by 33.5 Bcf to reach 56.3 Bcf, approximately 2.5 times the current capacity. Injection capacity will increase to 1.90 MMDth/day, while withdrawal capacity remains at 2.40 MMDth/day.
The first storage cavern is already fully subscribed under a long-term contract with Kinder Morgan (KMI). The project, expected to be in-service by 2028, includes construction of compression, dehydration, saltwater disposal wells, and related facilities. The facility serves markets through interconnects with Southern Natural Gas, Southeast Supply Header, and Transcontinental Gas Pipe Line.
Enstor Gas ha ottenuto l'approvazione della FERC per il suo Progetto di Espansione del Mississippi Hub, con l'inizio dei lavori previsto dopo la decisione finale di investimento (FID). Il progetto prevede l'ampliamento dell'impianto sotterraneo di stoccaggio di gas naturale nella contea di Simpson, Mississippi, aggiungendo tre caverne di stoccaggio con una capacità di 10 Bcf ciascuna.
L'espansione aumenterà la capacità totale di stoccaggio di gas operativo di 33,5 Bcf, raggiungendo 56,3 Bcf, circa 2,5 volte la capacità attuale. La capacità di iniezione salirà a 1,90 MMDth/giorno, mentre la capacità di prelievo rimarrà a 2,40 MMDth/giorno.
La prima caverna di stoccaggio è già completamente sottoscritta tramite un contratto a lungo termine con Kinder Morgan (KMI). Il progetto, previsto in esercizio entro il 2028, include la costruzione di compressori, impianti di disidratazione, pozzi per lo smaltimento di acqua salata e infrastrutture correlate. L'impianto serve i mercati attraverso collegamenti con Southern Natural Gas, Southeast Supply Header e Transcontinental Gas Pipe Line.

확장으로 총 작업용 가스 저장 용량이 33.5 Bcf 증가하여 56.3 Bcf에 이르며, 이는 현재 용량의 약 2.5배에 해당합니다. 주입 용량은 하루 1.90 MMDth로 증가하고, 인출 용량은 하루 2.40 MMDth로 유지됩니다.
첫 번째 저장 동굴은 이미 Kinder Morgan (KMI)와의 장기 계약으로 완전히 예약되었습니다. 이 프로젝트는 2028년까지 가동될 예정이며, 압축기, 탈수 시설, 염수 처리 우물 및 관련 시설의 건설을 포함합니다. 이 시설은 Southern Natural Gas, Southeast Supply Header, Transcontinental Gas Pipe Line과의 연결을 통해 시장에 공급합니다.
Enstor Gas a obtenu l'approbation de la FERC pour son projet d'expansion du Mississippi Hub, avec un début des travaux prévu après la décision finale d'investissement (FID). Le projet vise à étendre l'installation de stockage souterrain de gaz naturel dans le comté de Simpson, Mississippi, en ajoutant trois cavernes de stockage d'une capacité de 10 Bcf chacune.
L'expansion augmentera la capacité totale de stockage de gaz actif de 33,5 Bcf pour atteindre 56,3 Bcf, soit environ 2,5 fois la capacité actuelle. La capacité d'injection passera à 1,90 MMDth/jour, tandis que la capacité de retrait restera à 2,40 MMDth/jour.
La première caverne de stockage est déjà entièrement souscrite via un contrat à long terme avec Kinder Morgan (KMI). Le projet, prévu pour être opérationnel d'ici 2028, comprend la construction de compresseurs, d'installations de déshydratation, de puits de rejet d'eau salée et d'installations connexes. L'installation dessert les marchés via des interconnexions avec Southern Natural Gas, Southeast Supply Header et Transcontinental Gas Pipe Line.
Enstor Gas hat die FERC-Zulassung für sein Mississippi Hub Expansion Project erhalten, wobei der Baubeginn nach der endgültigen Investitionsentscheidung (FID) geplant ist. Das Projekt erweitert die unterirdische Erdgas-Speicheranlage im Simpson County, Mississippi, durch Hinzufügung von drei Speicherhöhlen mit jeweils 10 Bcf Kapazität.
Die Erweiterung erhöht die gesamte nutzbare Gasspeicherkapazität um 33,5 Bcf auf 56,3 Bcf, was etwa dem 2,5-fachen der aktuellen Kapazität entspricht. Die Einspritzkapazität steigt auf 1,90 MMDth/Tag, während die Entnahmekapazität bei 2,40 MMDth/Tag bleibt.
Die erste Speicherhöhle ist bereits vollständig durch einen langfristigen Vertrag mit Kinder Morgan (KMI) ausgelastet. Das Projekt, das voraussichtlich bis 2028 in Betrieb genommen wird, umfasst den Bau von Kompressions-, Entwässerungs-, Salzabwässer-Brunnen und zugehörigen Anlagen. Die Anlage versorgt Märkte über Anschlüsse an Southern Natural Gas, Southeast Supply Header und Transcontinental Gas Pipe Line.

Insights
The FERC approval of Enstor's Mississippi Hub Expansion Project represents a strategic win for Kinder Morgan that strengthens its competitive position in the growing Southeast natural gas market. KMI has secured a long-term contract for one of three new storage caverns, demonstrating foresight in capturing critical infrastructure ahead of projected demand growth.
This expansion directly supports KMI's existing Southeast regional growth initiatives, including the Evangeline Pass, Mississippi Crossing, and South System Expansion 4 projects. The additional storage capacity creates significant operational synergies with KMI's extensive pipeline network, enhancing service offerings to customers seeking flexibility during periods of price volatility.
For midstream operators like KMI, natural gas storage facilities generate stable, predictable cash flows through fixed-fee contracts, supporting the company's low-risk business model. While the 2028 in-service timeline means this won't impact near-term financials, it provides visibility into KMI's long-term growth trajectory.
The expansion's timing aligns perfectly with accelerating LNG export development along the Gulf Coast and increased natural gas-fired power generation – both key demand drivers in KMI's core markets. This positioning allows KMI to capitalize on these structural growth trends while providing essential balancing services as renewable energy penetration increases.
By securing this capacity early, KMI demonstrates management's conviction in sustained natural gas demand growth and reinforces the company's commitment to developing integrated midstream solutions that extend beyond simple pipeline transportation.

The expansion plan includes three additional storage caverns at Mississippi Hub, each with approximately 10 billion cubic feet (Bcf) of working storage capacity as well as incremental expansion of Mississippi Hub’s existing caverns. The project also includes the construction of compression, dehydration, saltwater disposal wells, and related facilities to accommodate the expansion. In total, the Mississippi Hub Expansion Project will add up to 33.5 Bcf of new working gas capacity and up to 0.7 million dekatherms per day (MMDth/day) of new injection capacity. Upon completion of the expansion, Mississippi Hub’s total working gas storage capacity is expected to be 56.3 Bcf, approximately 2.5 times the facility’s present capacity. The injection capacity will increase to a total of 1.90 MMDth/day and the withdrawal capacity will remain at 2.40 MMDth/day, as previously certificated before the expansion.
“We are pleased to have received FERC’s approval for our Mississippi Hub Expansion Project, and look forward to moving ahead with construction,” said Enstor CEO Paul Bieniawski. “This Expansion Project will not only enhance reliability and flexibility for our customers in the Gulf Coast and Southeast markets, but it will also provide significant additional natural gas storage capacity at a time when it’s needed most. With
The first of the three new storage caverns is already fully subscribed under a long-term contract with a subsidiary of Kinder Morgan, Inc. (NYSE: KMI) for storage services on Southern Natural Gas and Tennessee Gas Pipeline systems, as this particular corridor is undergoing tremendous growth due to increasing demand from LNG exports and power generation.
“Expansion projects underway for the Southeast region, including Evangeline Pass, Mississippi Crossing and the South System Expansion 4 projects, are the direct result of significant natural gas demand expectations for the near future. With growing natural gas demand, there is a need for additional storage in this region,” said KMI East Region Chief Commercial Officer Ernesto Ochoa. “During times of volatile natural gas pricing or for operational flexibility, storage provides customers with optionality. Additional storage coupled with our extensive network further enhances the services we can provide our customers.”
