Columbia Gas Transmission (TCO)

Force Majeure – MXP Line, Effective October 14, 2026

SEV 5/5
Force Majeure 1.900 Bcf/d Until Further Notice

TCO has declared a new Force Majeure effective Gas Day October 14, 2026, due to a detected leak near the Saunders Creek Regulator Station in West Virginia on MXP Line-100 -- explicitly separate from the September 24 FM (Notice 26276009). Effective the Evening Cycle of October 15 and until further notice, scheduled volumes through the MXPSEG MA42 internal constraint are reduced to zero total capacity, with estimated firm service impact of 1.9 MMDth/d (1.9 Bcf/d). Live capacity data at MXPSEG (loc_id MXPSEG, dir TD1:SGQ:FTS) already shows NON-FIRM-RESTRICTED with zero operating capacity posted against 1.85 Bcf/d scheduled as of the timely cycle on Oct 14, corroborating the constraint. TCO will provide an update by Friday morning October 16.

New TCO force majeure on MXP Line-100 eliminates 1.9 Bcf/d of Appalachian firm transport capacity to zero effective Oct 15 evening cycle (MXPSEG already NON-FIRM-RESTRICTED at 1.85 Bcf/d scheduled vs zero operating capacity in the Oct 14 timely cycle); expect significant bullish pressure on Dominion South, TETCO M2, and downstream Mid-Atlantic basis, with bearish pressure at Appalachian receipt points where gas backs up in-basin -- this is a second, independent TCO FM active simultaneously with the Sep 24 event.
Reroute: Limited to moderate: TETCO (monitored) and Equitrans serve overlapping Appalachian markets and provide partial reroute, but with 1.9 Bcf/d of firm capacity offline and a simultaneous active TCO force majeure from September 24 still in effect, the combined system stress severely limits practical bypass options for affected shippers.

Southern Star

Line Segment 455 Operational Capacity Reduction -- Force Majeure Update (Supersedes #11238)

SEV 4/5
Force Majeure 0.205 Bcf/d Until Further Notice 14 Days

Southern Star declared force majeure on Line Segment 455 due to a mechanical turbine failure at Saginaw Compressor Station in Jasper County, Missouri, effective October 9, 2026 (ID2 cycle). Capacity reductions total 205,000 Dth/d (0.205 Bcf/d): 180,000 Dth/d at Saginaw CS (Location ID 444550) and 25,000 Dth/d at Empire Energy Center (Location ID 378502). This notice (11240) supersedes 11238 and adds a repair timeline -- contractors are scheduled to complete turbine repairs by October 26, 2026, approximately two weeks from the notice date.

Southern Star force majeure removes 0.205 Bcf/d of Midcontinent/Kansas-Missouri capacity through approximately October 26; expect mild bullish pressure on Southern Star basis and Kansas-Missouri delivery markets, with tightening most acute at points downstream of Saginaw CS -- live data shows Saginaw CS Area Deliveries (loc 444550) running at 83.9% utilization with only 16.1% headroom, consistent with the stated constraint.
Reroute: Moderate: ANR, PEPL, and Southern Natural (EGT) serve overlapping Midcontinent and Kansas-Missouri markets, though Southern Star serves specific local delivery points in Missouri that may have limited bypass. PEPL Princeton Receipt (loc 17131) is posting 74.5% utilization with 25.5% headroom, suggesting some alternative capacity exists.

Southern Star

Line Segment 455 Operational Capacity Reduction -- Force Majeure

SEV 4/5
Force Majeure 0.205 Bcf/d Until Further Notice

Southern Star declared force majeure effective October 9, 2026 due to a mechanical failure at Saginaw Compressor Station in Jasper County, Missouri. The event reduces capacity by 180,000 Dth/d (0.180 Bcf/d) at Saginaw CS (Location ID 444550) and 25,000 Dth/d (0.025 Bcf/d) at Empire Energy Center (Location ID 378502), for a combined 0.205 Bcf/d reduction on Line Segment 455. No restoration timeline has been given; Southern Star will post updates as available.

Southern Star force majeure removes 0.205 Bcf/d of Midcontinent throughput capacity on Line Segment 455 with no restoration timeline; expect bullish pressure on Southern Star / Midcontinent Kansas-Missouri basis with tightening likely to spill into Oneok Oklahoma pricing and modest supportive signal at Henry Hub if Midwest pull-back reduces southbound displacement.
Reroute: Moderate: ANR, PEPL, and TIGT serve overlapping Midcontinent and Kansas/Missouri markets and could absorb a portion of the displaced volumes, but Southern Star Line Segment 455 serves specific local and downstream Missouri delivery points that may have limited bypass options.

ANR Pipeline (TC Energy)

NOTICE OF FORCE MAJEURE ANRPL – Michigan Leg South – St. John Eastbound

SEV 4/5
Force Majeure 0.395 Bcf/d cut (capped at 0.930 Bcf/d) Until Further Notice 17 Days

ANR Pipeline has declared a force majeure on the Michigan Leg South at St. John Eastbound (LOC #FPSTJNEB) due to an anomaly discovered between MLV 56 and MLV 57, restricting capacity by 395 MMcf/d (0.395 Bcf/d) and leaving only 930 MMcf/d available. The constraint, originally set to run from 10/3 through 10/12, has now been extended through 10/19, a total of 17 days. ANR anticipates firm primary curtailments of approximately 34% of contracted MDQ, with firm secondary and interruptible services also affected.

ANR force majeure removes 0.395 Bcf/d of Michigan Leg South eastbound capacity through 10/19; pre-event flow at St. John Eastbound (FPSTJNEB TD1) was running at a median 0.67 Bcf/d (range 0.59-0.75) against the now-constrained 0.977 Bcf/d operating capacity, with the new 0.930 Bcf/d cap implying a modest physical cut relative to recent scheduled flows of ~0.593 Bcf/d currently posted, but firm primary curtailments at 34% of MDQ signal tightening at ANR ML 7 Michigan/Wisconsin delivery markets.
Reroute: Limited: ANR is one of the primary pipelines serving Michigan and Wisconsin markets; NGPL, PEPL, and ANR's own alternative segments provide partial relief but cannot fully replace constrained Michigan Leg South eastbound capacity, particularly for firm primary shippers already facing 34% MDQ curtailments.

Tennessee Gas Pipeline (TGP)

FORCE MAJEURE ON MUSKRAT EFF 10-9-26

SEV 4/5
Force Majeure Until Further Notice

Tennessee Gas Pipeline has declared a force majeure on its Muskrat Line (Segments 509, 515, 516, 523, and 524) effective Gas Day October 9, 2026 and until further notice, due to evacuations in the Cocodrie, Louisiana area driven by the projected path and landfall of Hurricane Isaias. Primary In the Path capacity at Segment 524 FH may be impacted as early as the Timely Cycle for October 9. No specific capacity volume is stated; duration is indeterminate (UFN).

TGP Muskrat Line force majeure effective 10-9-26 UFN removes Gulf Coast zone supply with no stated capacity figure but hurricane-driven evacuations at Cocodrie create immediate risk to primary firm service on Segments 509-524; expect bullish pressure on Tennessee Zone 0/1 downstream basis and potential widening at Transco Zone 4 as Gulf Coast TGP supply is at risk.
Reroute: Limited: Gulf South (monitored) and Columbia Gulf Transmission serve overlapping Gulf Coast corridors, but hurricane evacuation conditions affecting the Cocodrie area may simultaneously constrain other Gulf Coast infrastructure; reroute cannot be assumed reliable while Isaias threatens landfall.

CAPACITY REDUCTION Michigan Leg South - St. John Eastbound

SEV 3/5
Maintenance 0.545 Bcf/d cut (capped at 0.780 Bcf/d) Until Further Notice 3 Days

ANR Pipeline has planned maintenance on the Michigan Leg South in Will County, IL affecting the St. John Eastbound location (LOC #FPSTJNEB) from November 3-5, 2026 (3 days). Capacity will be reduced by 545 MMcf/d (0.545 Bcf/d), leaving 780 MMcf/d (0.780 Bcf/d) available. ANR explicitly warns of Firm Primary, Firm Secondary, and Interruptible curtailments, estimating a 45% impact to Firm Primary MDQ -- a meaningful firm service impact over the 3-day window.

St. John Eastbound was carrying a median of ~0.64 Bcf/d (TD1) and ~0.20 Bcf/d (TD2) pre-event (range 0.59-0.67 and 0.18-0.35 respectively over the prior 7 days); the 0.780 Bcf/d cap sits above recent TD1 flow alone but combined scheduled throughput across both delivery cycles (~0.84-0.86 Bcf/d) implies a net cut of roughly 0.06-0.08 Bcf/d with firm curtailments at 45% of contracted MDQ, bullish for ANR ML 7 and Michigan/Wisconsin basis November 3-5.
Reroute: Moderate: ANR overlaps with TETCO, NGPL, and ANR's own parallel segments in the Illinois/Michigan corridor, but firm curtailments at 45% of MDQ suggest limited available alternative capacity on competing pipes for affected shippers during this window.

Cove Point Liquefaction Terminal Maintenance Complete

SEV 2/5
Maintenance 1 Days

Cove Point LNG liquefaction terminal maintenance has been completed as of October 12, 2026. The notice is a restoration/completion advisory rather than a new constraint -- it signals a return to normal feedgas operations. Live capacity data shows COVE POINT PLANT (D:DPQ) at 87.4% utilization (0.804 Bcf/d scheduled against 0.920 Bcf/d operating capacity), consistent with resumed normal operations; pre-event point history showed only 0.01 Bcf/d, suggesting the maintenance period coincided with reduced feedgas flows that are now recovering.

Maintenance completion at Cove Point LNG restores feedgas demand; pre-event scheduled quantity at COVE POINT PLANT had been suppressed to ~0.01 Bcf/d, now recovered to 0.804 Bcf/d (87.4% utilization per evening cycle 2026-10-12), which withdraws gas that had been stranded in the domestic market during the outage and is mildly bearish Henry Hub and Gulf Coast basis as LNG export demand resumes.
Reroute: Not applicable -- this is a restoration notice. Cove Point LNG is the sole LNG export terminal at this Maryland facility; no reroute exists for LNG feedgas deliveries here.

Tennessee Gas Pipeline (TGP)

FORCEMAJEURE MUSKRAT LINE RESOLVED 10-11

SEV 2/5
lifted ✓ Restoration 2 Days

TGP is posting resolution of the force majeure declared on its Muskrat Line (Segments 509, 515, 516, 523, 524) effective October 9, 2026, which was triggered by Hurricane Isaias evacuations at the Cocodrie, Louisiana area facilities. Personnel have returned and operations are returning to normal, with full nominations scheduled to restore effective the Timely Cycle for Gas Day October 11, 2026. This is the final update for this outage; the constraint lasted approximately two gas days.

TGP Muskrat Line force majeure resolved; full scheduling through Segment 524 FH resumes October 11 Timely Cycle, removing any residual bullish pressure on Gulf Coast and Southeast TGP basis points -- no new market impact from this notice.
Reroute: Moderate: Tennessee Gas Pipeline overlaps with SNG (unmonitored), Transco, and ANR in Gulf Coast and Southeast corridors, though the Muskrat Line serves specific offshore/Cocodrie-area receipt points with limited direct bypass. Moot given the restoration.
