Texas Eastern Transmission (TETCO)
Tompkinsville and Danville Compressor Stations on Line 15 Valve Sections 2 - 4 -- UNPLANNED OUTAGE
SEV 4/5
Capacity Constraintcapped at 1.528 Bcf/d, cut unknown
TETCO has declared an unplanned outage between Tompkinsville and Danville Compressor Stations on Line 15 Valve Sections 2-4, requiring an immediate pressure restriction effective Gas Day October 6, 2026. North-to-South capacity on the 30-inch system is reduced to a minimum of approximately 1.528 Bcf/d at Tompkinsville, Barton, and Danville stations, with no restoration timeline provided (UFN). Receipt meters between Berne and Uniontown compressor stations are also experiencing higher-than-normal pressures until further notice.
TETCO unplanned Line 15 outage caps southbound 30-inch system capacity to ~1.528 Bcf/d at the Tompkinsville/Barton/Danville bottleneck with no restoration date; net reduction is unquantified without a pre-event baseline for these mainline stations, but the UFN duration and unplanned nature support bullish M-3 Mid-Atlantic basis pressure and bearish pressure on Appalachian M-2 receipt points as northbound Marcellus gas is stranded.
Reroute: Moderate: TETCO M-2 volumes may seek alternative southbound or eastbound paths via TCO (Columbia Gas Transmission) or Transco, but TETCO is one of the highest-capacity Appalachian takeaway pipes and partial reroute will not fully offset a multi-station mainline restriction.

Texas Eastern Transmission (TETCO)
Tompkinsville and Danville Compressor Stations on Line 15 Valve Sections 2 - 4 -- Force Majeure
SEV 4/5
Force Majeure
TETCO has declared a Force Majeure due to an unplanned outage on its 30-inch system north of Tompkinsville Compressor Station in Kentucky, affecting Line 15 Valve Sections 2-4 and also implicating Danville Compressor Station. The restoration timeline is unknown ('unclear at this time'), and remediation plans are still being developed. No specific capacity volume has been stated in the notice, and the Tompkinsville, KY delivery meter (loc_id 70429) shows negligible scheduled flow (0.0 Bcf/d) as of 2026-10-30, suggesting the constraint is on the mainline compressor/segment rather than captured at that small delivery tap.
TETCO Force Majeure on Line 15 north of Tompkinsville, KY (UFN) restricts northbound capacity on the 30-inch system through Kentucky, bullish TETCO M-3 Mid-Atlantic basis as Appalachian-origin and Gulf Coast gas moving toward M-3 and Northeast markets faces reduced throughput; no volume quantified in notice.
Reroute: Limited to moderate: Texas Eastern (TETCO) is one of two dominant high-capacity pipelines moving gas north toward Mid-Atlantic and Northeast markets, with Transco providing the primary alternative for M-3 deliveries. However, Transco's own utilization in this corridor frequently runs high, and full reroute of any significant TETCO Line 15 volume constraint is unlikely without basis widening.

Texas Eastern Transmission (TETCO)
Tompkinsville and Danville Compressor Stations on Line 15 Valve Sections 2 - 4 -- UNPLANNED OUTAGE -- UPDATE
SEV 3/5
Capacity Constraint
TETCO is providing an update on the unplanned outage on Line 15 between the Tompkinsville and Danville compressor stations (Valve Sections 2-4), originally posted under Notice 183681. Primary Firm nomination restrictions remain in effect with no fixed end date; TETCO targets a return to service during the first week of November 2026, with greater clarity expected by October 23, 2026. No new capacity figures are provided in this revision, and the Tompkinsville, KY delivery point (loc_id 70429) shows near-zero scheduled flow (0.0000 Bcf/d) with essentially full operating capacity of 0.0038 Bcf/d available, suggesting this delivery meter does not reflect the mainline segment impact.
TETCO Line 15 unplanned outage continues to restrict Primary Firm nominations between Tompkinsville and Danville CS with no quantified volume impact stated; target return first week of November is the key date to watch for M-3 Mid-Atlantic basis relief, with no new market signal in this update.
Reroute: Limited to moderate: Transco serves overlapping Mid-Atlantic and Northeast markets and is the primary reroute option, but TETCO is a dominant high-capacity corridor and full substitution is unlikely without spare Transco capacity confirmation.
TETCO has experienced an unplanned outage at its Lebanon, Ohio compressor station, reducing east-to-west capacity through Berne, Sarahsville, and Somerset to approximately 0.579 Bcf/d and Five Points/Lebanon to 0.676-0.678 Bcf/d. Non-primary nominations at Sarahsville, Five Points, and Lebanon will be restricted beginning Gas Day August 28, 2026, with no firm end date provided. Restoration timeline is unknown; TETCO states updates will follow as repairs progress.
Unplanned Lebanon CS outage cuts TETCO eastbound capacity to 0.579 Bcf/d at the tightest point (Berne/Sarahsville/Somerset) effective August 28; with TETCO M-3 basis already at -1.160 vs Henry Hub as of 2026-08-26, further Mid-Atlantic tightening is likely while Appalachian M-2 supply backs up west of the outage.
Reroute: Limited: Transco (monitored) is the primary competing Mid-Atlantic pipeline and provides partial alternative capacity, but cannot fully replace TETCO M-3 deliveries at comparable volumes; TCO and EGTS serve overlapping Appalachian markets but do not replicate TETCO's Mid-Atlantic reach.

Texas Eastern Transmission (TETCO)
08/06/2026- TE Operational Advisory -- UPDATE
SEV 4/5
Operational AlertUntil Further Notice
TETCO has declared an operational advisory effective August 6, 2026, requiring all shippers and point operators in Market Area Zones M2 and M3 to perform to scheduled quantities due to large pipeline imbalances that Texas Eastern cannot manage with existing flexibility. The notice threatens OFOs and underperformance reductions if compliance is not achieved, and remains in effect until further notice with no restoration timeline. This is a first-revision superseding notice (prior notice 181374), indicating an escalation from an earlier advisory.
TETCO M2 and M3 imbalance advisory with OFO threat and no end date tightens Mid-Atlantic and Appalachian supply, expect bullish pressure on TETCO M2, TETCO M3, and Transco Zone 5 basis vs Henry Hub as shipper curtailments and underperformance reductions bite.
Reroute: Limited to moderate: Transco serves overlapping Mid-Atlantic markets and is the primary competing pipeline for M3 deliveries; however, simultaneous demand pressure on both TETCO and Transco in the Mid-Atlantic corridor limits the degree to which volumes can be shifted without further basis widening.
