CAPACITY REDUCTION Non-Performance at Patterson/Neptune (LOC #505655) - Southeast Area

SEV 5/5
Capacity Constraint 0.500 Bcf/d Until Further Notice

ANR Pipeline has declared a critical capacity restriction effective immediately at the Patterson/Neptune receipt location (LOC #505655) in St. Mary Parish, Louisiana, due to non-performance. Starting 7/23 and until further notice, scheduled capacity is reduced by 0.500 Bcf/d, leaving only 0.100 Bcf/d available at this location. ANR explicitly anticipates Firm Primary, Firm Secondary, and Interruptible curtailments -- all service classes are at risk.

ANR restricts 0.500 Bcf/d at Patterson/Neptune (SE Louisiana) with firm primary curtailments anticipated and no restoration timeline; expect bearish Henry Hub pressure as Gulf Coast northbound takeaway backs up, with potential bullish signal at Midwest/Chicago markets losing this supply.
Reroute: Moderate: TETCO, Trunkline (TGC), and Southern Natural (EGT) serve overlapping Gulf Coast northbound corridors, but the 0.500 Bcf/d reduction at a single receipt point is large relative to typical spare capacity and firm curtailments across all service classes suggest limited ability to absorb volumes at alternative paths without congestion.

UPDATED: CAPACITY REDUCTION Michigan Leg North – Rabbit River MS

SEV 4/5
Maintenance 0.083 Bcf/d Until Further Notice 40 Days

ANR Pipeline has rescheduled planned maintenance on the Michigan Leg North at Rabbit River Meter Station (Allegan County, MI), shifting the window from 7/30-8/24 to 8/6-9/14. During this 40-day period, capacity at Loc #523093 is reduced to zero from 83 MMcf/d (0.083 Bcf/d), with 100% curtailment of firm primary service expected based on both current nominations and contracted MDQ. This supersedes prior notice 26116014.

ANR removes 0.083 Bcf/d of firm delivery capacity at Rabbit River MS through 9/14, with 100% firm primary curtailment anticipated; expect tightening of Michigan/Midwest local basis and potential shipper displacement into alternative Midwest supply paths for the extended 40-day window.
Reroute: Moderate: ANR serves overlapping Midwest/Michigan markets alongside PEPL, TGT, and TETCO, which may absorb some displaced volumes, though Rabbit River MS serves specific local Allegan County distribution points that may have limited bypass options within the Michigan Leg North segment.

Transwestern Pipeline

[Transwestern Pipeline] [Capacity Constraint] EAST MAINLINE

SEV 4/5
Force Majeure 1 Days

Transwestern Pipeline has declared a force majeure on the East Mainline, effective July 29, 2026 at 9:00 AM through July 30, 2026 at 8:59 AM. The East Mainline is the primary eastbound/westbound corridor carrying Permian Basin and San Juan Basin gas westward toward SoCal Border and Arizona delivery points. No specific capacity volume has been stated in the notice.

TW East Mainline force majeure tightens Permian westbound takeaway for approximately 1 day; expect bearish pressure at Waha as basin gas backs up, with bullish pressure at SoCal Border and Arizona delivery points -- monitor EPNG spare capacity as the primary reroute alternative.
Reroute: Moderate: El Paso Natural Gas (EPNG) is the primary competing pipeline for SoCal border and Arizona deliveries and may absorb some displaced TW volumes, but a simultaneous EPNG constraint would eliminate California reroute entirely. EPNG spare capacity availability is the critical variable.

[Transwestern Pipeline] [Force Majeure] Force Majeure - Station 8 Compressor Station (Corona, NM). 7/29/26

SEV 4/5
Force Majeure 0.150 Bcf/d 2 Days

Transwestern Pipeline has declared a force majeure at Station 8 Compressor Station (Corona, NM) due to a mechanical failure, effective July 29, 2026 at 9:00 AM through July 31, 2026 at 8:59 AM. Westbound capacity through Station 9 (Roswell, NM) is reduced from 750,000 MMBtu/d to 600,000 MMBtu/d, a loss of approximately 0.150 Bcf/d affecting West Texas and Panhandle lateral volumes flowing west. Restoration to full capacity is scheduled for Gas Day July 31, 2026.

TW force majeure at Station 8 removes 0.150 Bcf/d of westbound Permian/Panhandle takeaway capacity; expect bearish pressure at Waha as basin gas backs up and bullish pressure at SoCal Border and Arizona delivery points as westbound supply tightens.
Reroute: Moderate: EPNG serves overlapping westbound Permian-to-SoCal Border and Arizona markets and is the primary competing pipeline; however, summer cooling demand may limit available spare capacity on EPNG, partially offsetting reroute potential.

ANR Pipeline (TC Energy)

CAPACITY REDUCTION Michigan Leg South - St. John Eastbound

SEV 4/5
Maintenance 0.750 Bcf/d Until Further Notice 5 Days

ANR Pipeline has planned maintenance on the Michigan Leg South segment at St. John Eastbound (LOC #FPSTJNEB) from 8/30 through 9/3/2026. Capacity is reduced by 545 MMcf/d (leaving 780 MMcf/d) on 8/30-8/31, then by 750 MMcf/d (leaving 575 MMcf/d) on 9/1-9/3. ANR explicitly warns of Firm Primary, Firm Secondary, and Interruptible curtailments, with firm primary impact estimated at 10-45% on 8/30-8/31 and 34-59% on 9/1-9/3 based on contracted MDQ.

ANR Michigan Leg South eastbound reduction of up to 0.750 Bcf/d with confirmed firm primary curtailment risk (up to 59% of contracted MDQ on 9/1-9/3) tightens Gulf Coast-to-Midwest flows and is bullish for Chicago Citygate and Midwest basis versus Henry Hub during the affected gas days.
Reroute: Moderate: TETCO, PEPL, and TGT serve overlapping Gulf Coast-to-Midwest corridors, but the scale of firm primary curtailments (up to 59% of contracted MDQ) may exceed available alternative capacity on those systems, particularly during late-August/early-September shoulder demand.

Freeport LNG Feed

[CAPACITY CONSTRAINT] ANT PIP DELIVERY RESTR TO CARNES 7-25

SEV 4/5
Capacity Constraint 1 Days

A capacity constraint is restricting Ant Pipeline deliveries to the Carnes compressor/delivery point serving Freeport LNG feed gas, effective July 24, 2026 at 1:16 PM through July 25, 2026 at 9:00 AM. No specific volume curtailment is stated in the notice. The event is short-duration, approximately 20 hours, but directly affects Freeport LNG feed gas supply.

Freeport LNG feed gas delivery restriction via Ant Pipeline reduces LNG export demand pull at the Gulf Coast; expect near-term bearish pressure at Henry Hub and Gulf Coast basis points until restoration at 09:00 CT July 25.
Reroute: Limited: Freeport LNG feed gas supply is dependent on specific upstream gathering and transmission laterals; no volume figure is provided to assess alternative routing, and LNG feed gas laterals typically have limited bypass options.

Tennessee Gas Pipeline (TGP)

FORCE MAJEURE 538-2 - 539-2 UPDATE #1

SEV 4/5
Force Majeure Until Further Notice 2 Days

Tennessee Gas Pipeline has declared a Force Majeure on Line 2 between MLV sections 538-2 and 539-2 near Heidelberg, Mississippi, effective July 23, 2026. An unplanned equipment issue requiring immediate repair has restricted Primary In the Path nominations through MLV 539 (Segment 534 BH) and limited receipts/deliveries at the Leaf Jasper County Meter (412789). TGP anticipates restoration by July 25, 2026, with full nominations expected to resume for the July 26 Gas Day Timely Cycle.

TGP Line 2 force majeure near Heidelberg, MS restricts primary firm capacity on a key Southeast supply corridor; expect short-term bullish pressure on Transco Zone 4 and Southeast basis with restoration targeted by July 25 evening.
Reroute: Limited: Transco serves overlapping Southeast markets and provides partial alternative, but SNG (Southern Natural Gas) is the only other major competing pipeline in the Gulf Coast-to-Southeast corridor; full reroute is unlikely given primary firm restrictions active on TGP Line 2.

Natural Gas Pipeline (NGPL)

[FORCE MAJEURE] FORCE MAJEURE - M&M LATERAL - SEG 3

SEV 4/5
Force Majeure 1 Days

NGPL has declared a force majeure on the M&M Lateral, Segment 3, effective July 23, 2026 at 1:07 PM with a stated end date of July 24, 2026 at 9:00 AM -- approximately 20 hours of impact. No specific capacity volume is stated in the notice. The M&M Lateral serves Midwest delivery points on the NGPL system, one of the highest-throughput pipelines serving Chicago and the broader Midwest market.

NGPL force majeure on M&M Lateral Seg 3 is bullish for Chicago Citygate and Midwest basis vs Henry Hub; short duration limits market impact but force majeure classification warrants monitoring for scope expansion given no capacity volume is disclosed.
Reroute: Moderate: ANR, PEPL, and REX Zone 3 serve overlapping Chicago and Midwest markets, though NGPL is very high capacity and large constraints are difficult to fully offset; the lack of a stated volume figure limits reroute assessment.

El Paso Natural Gas (EPNG)

[FORCE MAJEURE] Force Majeure - Line 1102

SEV 4/5
Force Majeure 1 Days

EPNG has declared a force majeure on Line 1102 effective 07/22/2026 at 11:58 AM, with restoration expected by 07/23/2026 at 9:00 AM. No specific capacity volume is stated in the notice. The event is short-duration (approximately 21 hours) but is an unplanned force majeure on a key Permian outbound segment.

EPNG Line 1102 force majeure traps Permian Basin gas at Waha (bearish Waha basis) while reducing westbound supply to SoCal Border and Arizona delivery points (bullish SoCal Border and AZ basis); no capacity volume disclosed, but duration is limited to roughly one gas day.
Reroute: Moderate: Transwestern Pipeline (TW) is the primary competing pipeline serving SoCal Border and Arizona delivery points from the Permian and San Juan Basin, and may absorb some displaced EPNG volumes, though spare capacity on TW is not confirmed and full offset is uncertain.

CAPACITY REDUCTION Michigan Leg South – East Joliet MS

SEV 3/5
Maintenance 0.328 Bcf/d Until Further Notice 4 Days

ANR Pipeline has planned maintenance at East Joliet Meter Station (LOC ID#4196) in Will County, IL from August 11-14, 2026. The full 0.328 Bcf/d capacity at this location will be reduced to zero for the four-day window. ANR explicitly anticipates Firm Secondary and Interruptible curtailments as a result.

ANR East Joliet MS goes to zero for 0.328 Bcf/d over Aug 11-14; expect bullish pressure at Chicago Citygate and Midwest basis points as northbound Michigan Leg South deliveries are curtailed, with Firm Secondary and Interruptible shippers at greatest risk.
Reroute: Moderate: TETCO, PEPL, and Southern Star serve overlapping Gulf Coast-to-Midwest corridors and may absorb some displaced volumes, though full replacement of 0.328 Bcf/d at this specific Illinois delivery point is unlikely given localized Michigan Leg South distribution.

CAPACITY REDUCTION Michigan Leg South – Crown Point MS

SEV 3/5
Maintenance 0.326 Bcf/d Until Further Notice 5 Days

ANR Pipeline has planned maintenance at Crown Point Meter Station (LOC #138744) in Lake County, Indiana on the Michigan Leg South from August 17-21, 2026. The outage eliminates the full 326 MMcf/d of capacity at this location, leaving 0 MMcf/d available for the 5-day window. ANR explicitly anticipates Firm Secondary and Interruptible curtailments as a result.

ANR Michigan Leg South loses 0.326 Bcf/d at Crown Point MS for five days (8/17-8/21), with firm secondary and interruptible curtailments expected; watch for tightening Chicago Citygate and Midwest basis as Gulf Coast northbound ANR throughput is constrained, with partial reroute pressure onto TETCO and PEPL.
Reroute: Moderate: TETCO, Panhandle Eastern (PEPL), and Trunkline (TGC) serve overlapping Gulf Coast-to-Midwest corridors and can absorb some diverted volumes, though simultaneous summer demand may limit available spare capacity on these alternatives.

FORCE MAJEURE 538-2 - 539-2 UPDATE #3

SEV 3/5
Force Majeure Until Further Notice 1 Days

Tennessee Gas Pipeline declared force majeure on Line 2 between valve sections 538-2 and 539-2 near Heidelberg, Mississippi effective July 23, 2026. This is Update #3 and represents a near-restoration notice: TGP anticipates completing final repairs by July 26, 2026, with full Primary In the Path service at MLV 539 (Segment 534 BH) expected to resume at Timely Cycle for Gas Day July 27, 2026. The Leaf Jasper County Meter (412789) will also return to full meter capacity nominations effective the same cycle.

TGP Line 2 force majeure near Heidelberg, MS is on the verge of full restoration effective July 27 Timely Cycle -- any bearish Southeast basis pressure from the original July 23 outage should reverse as supply restrictions lift on this segment.
Reroute: Moderate: during the outage period, Transco (monitored) and Southern Natural Gas (SNG/EGT, monitored) serve overlapping Gulf Coast and Southeast markets and likely absorbed displaced volumes; restoration removes the need for reroute.

Station 620 (Job 355854) 2026 Planned Outage Maintenance Summary

SEV 3/5
Maintenance 0.328 Bcf/d 15 Days

Transco will perform a planned turbine exchange on Main Unit 1 at Station 620 (Job 355854) from September 1 through September 15, 2026, impacting primary firm N-to-S flows on Central Penn Line South. Design capacity of 2,328 MDth/d is reduced to 2,000 MDth/d available, a loss of approximately 0.328 Bcf/d (85% of design). Primary firm shippers face estimated cuts of 5-10% based on historical utilization.

Transco planned maintenance removes approximately 0.328 Bcf/d of N-to-S primary firm capacity on Central Penn Line South from Sept 1-15; expect mild bullish pressure on Transco Zone 4 Southeast basis as southbound throughput is constrained during a period of typically moderate summer demand.
Reroute: Limited: Southern Natural Gas (SNG/EGT) provides a partial alternative for Southeast deliveries, but SNG capacity is significantly smaller than Transco and unlikely to absorb the full constraint volume; some shippers may manage via storage or demand response.

UPDATED.CAPACITY REDUCTION Michigan Leg North – Bridgman Northbound

SEV 3/5
Maintenance 0.679 Bcf/d Until Further Notice 26 Days

ANR Pipeline has updated planned maintenance at Hamilton Compressor Station in Allegan County, Michigan, shifting the start date to July 30 from July 28 and confirming a 0.679 Bcf/d capacity reduction on the Bridgman Northbound segment (LOC #FPBRGMNB), leaving 0.943 Bcf/d available. The outage runs July 30 through August 24, 2026 (26 days). ANR warns of potential Firm Primary, Firm Secondary, and Interruptible curtailments, estimating up to 35% impact on contracted MDQ though current nominations show 0% firm impact.

ANR Bridgman Northbound reduction of 0.679 Bcf/d through August 24 tightens northbound Gulf Coast-to-Midwest takeaway; watch for mild bearish pressure at Henry Hub and Gulf Coast origin points with modest bullish signal at Michigan/Chicago Citygate basis, though zero current firm nomination impact limits near-term price effect.
Reroute: Moderate: TETCO, Trunkline (TGC), and Panhandle Eastern (PEPL) serve overlapping Gulf Coast-to-Midwest corridors and can absorb some displaced volumes, though a 0.679 Bcf/d reduction is material and may not be fully offset if those pipes are running near capacity in summer.

Station 80 ESD Test (Job 596608) 2026 Planned Outage and Maintenance Summary

SEV 3/5
Maintenance 1.070 Bcf/d 3 Days

Transco has scheduled a planned compressor station outage at Station 80 (mainline milepost 740.5) from September 9-11, 2026 to perform ESD safety system testing. During the outage, southbound-to-northbound throughput capacity at the TSB location will be reduced from 3,421 MDth/d (3.421 Bcf/d) to 2,351 MDth/d (2.351 Bcf/d), representing a loss of approximately 1.070 Bcf/d or 69% of design capacity available. Primary firm service faces 0-5% potential cut exposure based on historical utilization.

Transco Station 80 planned maintenance removes approximately 1.070 Bcf/d of south-to-north capacity for 3 days in September, creating mild bullish pressure on downstream Southeast and Mid-Atlantic Transco basis points (Zone 4, Zone 5) relative to Henry Hub, with 0-5% primary firm cut risk.
Reroute: Moderate: Southern Natural Gas (SNG/EGT) provides a partial alternative for Southeast-bound volumes, and Tennessee Gas Pipeline (TGP) serves overlapping Northeast markets; however, Transco's dominant capacity position in this corridor means reroutes are unlikely to fully absorb the 1.070 Bcf/d reduction for shippers without pre-arranged alternative paths.

Pipeline Incident Impacting Service Update

SEV 2/5
Informational 99 Days

Texas Gas Transmission revision 4 of notice 5038467 provides no new operational detail -- no capacity volumes, curtailment levels, force majeure language, or timeline changes are included in this update. The event was originally posted 2026-07-24 with a scheduled end of 2026-11-01. This revision appears to be an administrative supersede update with no new market-moving information.

No new market impact -- operational situation unchanged from prior revision, market has already priced this constraint.
Reroute: Moderate: ANR, PEPL, and TETCO serve overlapping Gulf Coast-to-Midwest corridors and likely provide partial relief, though no specific affected segment or capacity figure is disclosed in this notice.

FORCE MAJEURE 538-2 - 539-2 RESOLVED

SEV 2/5
lifted ✓ Restoration 1 Days

Tennessee Gas Pipeline has resolved the force majeure event on Line 2 between MLV 538-2 and 539-2 near Heidelberg, Mississippi, originally declared July 23, 2026 (Notice #402947). Repairs are complete and the segment has returned to normal operations. Nominations will be accepted up to capacity through MLV 539 (Segment 534 BH) and at the Leaf Jasper County Meter (412789) until further notice.

TGP Line 2 force majeure near Heidelberg, MS is resolved effective July 27; restoration of southbound Gulf Coast throughput is mildly bullish for Southeast markets and removes any TGP-driven basis widening at Transco Zone 4 that may have developed since the July 23 outage.
Reroute: High: event is resolved; reroute assessment is moot as full capacity has been restored on TGP Line 2 near Heidelberg, MS.

2026 Major Construction and Maintenance Projects

SEV 1/5
Informational

Transco has posted an updated 2026 major construction and maintenance schedule superseding prior notice 17064602. The notice does not specify individual project dates, durations, or capacity impacts, and states that additional notices will be issued before any activity expected to affect transportation services. Only interruptible and secondary firm service are flagged as potentially affected; primary firm service is not mentioned as at risk.

No actionable trading signal at this time -- this is a schedule update notice with no specific capacity restrictions identified; watch for project-level follow-on notices that will detail segment, dates, and interruptible capacity impacts.
Reroute: Not applicable -- no specific capacity constraint has been identified in this notice; reroute assessment will be relevant when individual project notices are posted.
