Tennessee Gas Pipeline has declared a Force Majeure between MLV 538-2 and 539-2 on Line 2 near Heidelberg, Mississippi, effective July 23, 2026. An unplanned issue requiring immediate repairs will shut in meter 412789 (Leaf/TGP Jasper County), placing all receipts and deliveries at that meter at risk starting with Timely Cycle on July 23. No restoration timeline has been provided; TGP states it will update customers as more information becomes available.
TGP force majeure on Line 2 in Heidelberg, MS shuts in the Leaf/Jasper County meter with no stated restoration timeline, removing an indeterminate volume of Southeast supply and creating bullish pressure on Tennessee Zone 4 and Transco Zone 4 Southeast basis vs Henry Hub.
Reroute: Limited: Transco and Southern Natural Gas (SNG/EGT) serve overlapping Southeast markets, but the specific Leaf/Jasper County receipt point is directly tied to TGP Line 2 with no direct bypass; downstream Southeast deliveries dependent on this meter have limited reroute options.

ANR Pipeline (TC Energy)
CAPACITY REDUCTION - Southeast Area – Eunice Compressor Station
SEV 4/5
Maintenance2.265 Bcf/dUntil Further Notice7 Days
ANR Pipeline has planned maintenance at Eunice Compressor Station in Acadia Parish, Louisiana (Southeast Area) from August 4-10, 2026, resulting in firm primary, firm secondary, and interruptible curtailments. Nine delivery and interconnect locations face full or near-full capacity reductions totaling approximately 2.265 Bcf/d of constrained capacity, with Pine Prairie South Del completely shut (0.6 Bcf/d) and major curtailments at Shadyside/Sonat (0.431 Bcf/d to 0.150 remaining) and Shadyside/TGP (0.443 Bcf/d to 0.030 remaining). ANR estimates firm primary impact at 10% of current net nominations and 27% of contracted MDQ.
ANR Eunice CS maintenance removes approximately 2.265 Bcf/d of Southeast Area delivery capacity for 7 days (8/4-8/10), with firm primary curtailments affecting key interconnects to CGT (Columbia Gulf), TGP, Sonat/SNG, and Trunkline; expect bullish pressure at Henry Hub and Transco Zone 4 as Gulf Coast supply access tightens, with widening ANR Southeast-to-Midwest basis.
Reroute: Moderate: TETCO (monitored), Trunkline/TGC (monitored), and Southern Natural/SNG (EGT, monitored) serve overlapping Gulf Coast northbound corridors, but the scale of curtailments across multiple interconnects simultaneously -- including the Patterson/Trunkline and Patterson/Col Gulf links -- significantly limits the ability of alternatives to absorb the full volume; partial reroute possible but not sufficient to fully offset 2.265 Bcf/d of constrained capacity.

El Paso Natural Gas (EPNG)
[FORCE MAJEURE] Force Majeure - L3162
SEV 4/5
Force Majeure1 Days
El Paso Natural Gas has declared a force majeure on Line 3162 effective 07/21/2026 at 2:01 PM, with an expected restoration by 07/22/2026 at 9:00 AM -- approximately 19 hours of impact. No specific capacity volume is stated in the notice. L3162 is an EPNG mainline segment; as an outbound Permian Basin corridor, this event traps gas at Waha while reducing westbound supply to SoCal Border and Arizona delivery points.
EPNG FM on L3162 removes westbound Permian takeaway capacity for roughly 19 hours; expect bearish pressure at Waha as basin gas backs up and bullish pressure at SoCal Border and Arizona delivery points -- no volume stated but any mainline FM on EPNG is a firm market signal.
Reroute: Moderate: Transwestern Pipeline (TW) is the primary competing corridor for SoCal border and Arizona deliveries, but available spare capacity on TW at this time is uncertain and may not fully offset an EPNG mainline FM event.

El Paso Natural Gas (EPNG)
[OPERATIONAL FLOW ORDER] SOC Declaration - System Wide Draft
SEV 4/5
Operational Alert1 Days
EPNG has declared a System-Wide Operational Flow Order (OFO) / SOC (System Operational Condition) effective 07/21/2026 at 7:25 AM, expiring 07/22/2026 at 9:00 AM. The system-wide scope indicates EPNG is experiencing line pack stress or imbalance conditions across its entire network, spanning the Permian Basin eastward origin points through to SoCal Border and Arizona delivery points. No specific capacity volume is stated in the notice, but system-wide OFO declarations on EPNG signal operational stress requiring shippers to balance nominations immediately.
EPNG system-wide OFO creates immediate balancing pressure for all shippers; expect bearish Waha/Permian basis as takeaway is operationally constrained and bullish pressure at SoCal Border and Arizona delivery points as westbound deliveries tighten -- shippers out of balance risk cash-out penalties and forced curtailment through 9:00 AM 07/22.
Reroute: Moderate: Transwestern Pipeline (TW) is the primary competing pipeline serving SoCal Border and Arizona delivery points, and may absorb some displaced volumes; however, summer peak demand conditions likely mean TW is operating near capacity, limiting meaningful reroute relief.

Tennessee Gas Pipeline (TGP)
FORCE MAJEURE 113-2 TO 114-2 EFF 7-22-26
SEV 4/5
Force MajeureUntil Further Notice
Tennessee Gas Pipeline has declared a Force Majeure on Line 2 between MLV 113-2 and MLV 114-2 (Broad Run Lateral) in Boyd County, Kentucky near Catlettsburg, effective July 22, 2026, until further notice. The FM is triggered by a PHMSA Corrective Action Order (CAO) following an emergent repair that began July 8, 2026, which restricts operating pressures on Line 2 from Sta. 110 (Morehead, KY) to Sta. 114 (Catlettsburg, KY). As a result, nominations at Big Sandy Glancy Fork PIN 412742 will be reduced to zero, with potential for additional segment restrictions as nearby scheduled maintenance concludes.
TGP force majeure on Line 2 Appalachian segment (Sta. 110-114, KY) reduces Big Sandy Glancy Fork nominations to zero until further notice, tightening Appalachian southbound/downstream capacity and supporting bullish pressure at Transco Zone 4 Southeast and Dominion South basis vs Henry Hub.
Reroute: Moderate: Transco and Columbia Gas Transmission (TCO) serve overlapping Appalachian and Southeast corridors, but TCO and TETCO M2 capacity availability will determine how much of the stranded Big Sandy volume can be rerouted; additional TGP segment restrictions flagged as possible if nearby maintenance concludes, which could further limit reroute flexibility.

Texas Gas Transmission
Pipeline Incident Impacting Service Update
SEV 3/5
Operational Alert0.285 Bcf/dUntil Further Notice103 Days
Texas Gas Transmission is responding to a pipeline incident in Panola County, Texas on the North Louisiana Supply Lateral west of the Haughton Compressor Station, originally reported in early 2026. This latest revision extends the notice end date to November 1, 2026, with current Sharon Carthage scheduling group capacities capped at SCW=135,000, SCE=100,000, CEW=235,000, and SCP=285,000 MMBtu/day, plus the Sligo Location 2760 reduced to 0 MMBtu. The event originated months ago and has been progressively updated with evolving capacity restrictions and extended timelines.
TGT North Louisiana Supply Lateral constraint of up to 0.285 Bcf/d on the Sharon Carthage system is a long-running restriction now extended to November 1, 2026; expect modest continued bullish pressure on Gulf Coast-to-Midwest basis given TGT's role as a northbound artery, with Henry Hub slightly supported as Haynesville-area receipts remain constrained.
Reroute: Moderate: ANR, TETCO, and Gulf South serve overlapping Gulf Coast-to-Midwest corridors and can absorb some Sharon Carthage/North Louisiana supply rerouting, though TGT serves specific receipt points on the North Louisiana Supply Lateral that may not have direct alternatives.

Gulf South Pipeline
System Wide Alert - Limited Operational Flexibility
SEV 2/5
Informational
Gulf South Pipeline issued a System Wide Alert for Limited Operational Flexibility (Notice 5038424), originally posted 2026-07-15 and now on its third revision as of 2026-07-22. No specific capacity volumes, curtailment language, force majeure declaration, new affected locations, or restoration timeline are provided in this revision. The notice body contains no new operational information beyond the original alert.
No new market impact -- operational situation unchanged from prior revision, market has already priced this constraint.
Reroute: Moderate: Southern Natural Gas (EGT), Transco, and Tennessee Gas Pipeline serve overlapping Gulf Coast and Southeast markets that Gulf South supplies, providing partial reroute options if specific constraints were identified; however, no specific constrained segment or volume is stated in this notice.
Below alert threshold -- no detailed analysis performed.

Transco
Station 50 (Job 361708) Outage 2026 Planned Outage and Maintenance Summary
SEV 2/5
Maintenance0.100 Bcf/d1 Days
Transco is performing a planned one-day compressor station outage at Station 50 West (MP 517.23) on September 9, 2026 for safety systems testing. The event restricts south-to-north flow through the TSB, reducing available throughput from 1,535 MDt/d design capacity to 1,435 MDt/d, a loss of approximately 0.100 Bcf/d. Estimated shipper impact is 0-5% of primary firm volumes based on historical utilization.
Single-day planned Transco maintenance on September 9 removes approximately 0.100 Bcf/d of southbound-to-northbound capacity at Station 50 West; impact is negligible with 94% of design capacity remaining available and no firm curtailments expected.
Reroute: Moderate: Southern Natural Gas (SNG/EGT) and Tennessee Gas Pipeline serve overlapping Southeast-to-Northeast corridors and can absorb minor displacement volumes given the small capacity reduction involved.
Below alert threshold -- no detailed analysis performed.
Reroute: Not assessed.

Enable Gas Transmission (EGT)
[Enable Gas Transmission (EGT)] [Maintenance] SOUTH POOL INTEGRITY DIGS
SEV 2/5
Maintenance31 Days
Enable Gas Transmission (EGT) has issued a planned maintenance notice for integrity digs in its South Pooling Area beginning August 18, 2026, through September 18, 2026 (31 days). During this period, EGT will not allow IT and Secondary services from its West 1, West 2, Flex, and North Pooling Areas to the South Pooling Area, and will have limited ability to schedule receipts from Line AC meters (including MRT at Glendale and NGPL at Hot Springs) to South Pool delivery points. Shippers are advised to nominate from primary receipt to primary delivery points to maintain highest priority service. No specific capacity volume is stated.
Planned EGT South Pool maintenance restricts interruptible and secondary service flows for 31 days starting August 18; primary firm service is unaffected, so basis impact at Arkla/Oklahoma hubs is minor and shippers have over a month of advance notice to rearrange nominations.
Reroute: Moderate: Gulf South Pipeline and Southern Natural Gas (EGT via Energy Transfer) serve overlapping Arkla Basin and Southeast corridors and can absorb displaced IT volumes; however, shippers with firm South Pool delivery obligations should re-nominate from primary receipt points as directed by EGT.
Below alert threshold -- no detailed analysis performed.
