Delhi and Gwinville Compressor Station Unplanned Outages
Southeast Supply Header, LLC (SESH) has experienced an outage at one compressor unit at both its Delhi and Gwinville, Mississippi compressor stations. Repair efforts to restore these compressor stations to full capacity are underway.
As a result of this outage, beginning Gas Day October 24, 2025, SESH's mainline capacity will be limited to approximately:
Delhi: 934,000 Dth/d
Gwinville: 931,000 Dth/d
Gwinville East: 931,000 Dth/d
Lucedale: 1,101,000 Dth/d
Nominations for Gas Day October 23, 2025, will remain unimpacted. For Gas Day October 24, 2025, SESH will work with upstream and downstream interconnects to minimize shipper impacts due to the reduced capacities, however, if necessary and in order to protect the integrity of the pipeline, SESH may impose intraday restrictions to nominations. If restrictions are ultimately required for Gas Day October 24, SESH will endeavor to make these restrictions before or during the ID-1 cycle if possible.
Furthermore, due to the outages, SESH will have lower than typical operating pressures across its system. As such, in addition to the restrictions noted above, SESH may be required to reduce TGP - Petal (83108) delivery nominations to 0 due to SESH's lower pressure at this interconnect.
In addition, SESH will take into account these capacities and any operational assistance it is receiving for Gas Day October 25, 2025, until further notice. SESH anticipates the outages at both compressor units to be repaired and returned to full operation by approximately October 30, 2025. SESH will post updates to the status of the repairs as soon as it is known.
