[Trailblazer Pipeline (TPC)] [OPERATIONAL ALERT] THIRD PARTY OPERATIONAL ISSUE - BERTRAND COMPRESSOR STATION - UPDATE #14
SEV 5/5
Compressor Issue0.808 Bcf/dUntil Further Notice
Trailblazer Pipeline Segment 20 remains restricted to 0.808 Bcf/d effective Gas Day June 2, 2026, until further notice due to an ongoing third-party operational issue at Bertrand Compressor Station -- now in its 14th update. Primary firm, secondary firm, and ITS/AOR quantities are all explicitly at risk of not being scheduled. No restoration timeline has been provided.
Bertrand CS constraint caps Trailblazer at 0.808 Bcf/d with firm service at risk; because REX leases capacity at the same Bertrand CS facility, these two Rockies eastbound pipes are simultaneously constrained -- expect continued bearish pressure on Rockies basin (CIG/Cheyenne Hub) as eastbound takeaway remains impaired with no reroute.
Reroute: None: Trailblazer and REX share the Bertrand Compressor Station -- the same third-party facility constraining Trailblazer simultaneously affects REX Zone 1, eliminating the primary reroute alternative for Rockies eastbound volumes.
Rockies Express
[OPERATIONAL ALERT] BERTRAND COMPRESSOR STATION OPERATIONAL ISSUE - UPDATE #14
SEV 5/5
Compressor Issue1.115 Bcf/dUntil Further Notice
Rockies Express Bertrand Compressor Station operational issue (Update #14) restricts Segment 250 West-to-East capacity to 1.115 Bcf/d effective Gas Day June 2, 2026, until further notice. Primary firm, secondary firm, and interruptible service are all at risk of not being scheduled. No restoration timeline has been provided.
REX Segment 250 constrained to 1.115 Bcf/d W-to-E with primary and secondary firm at risk; Trailblazer shares Bertrand CS and is simultaneously affected -- expect bullish pressure at Midcontinent and Chicago Citygate as Rockies takeaway is curtailed with zero independent reroute.
Reroute: None: REX and Trailblazer share Bertrand Compressor Station -- both are simultaneously constrained by the same facility, leaving no independent reroute for Rockies eastbound volumes. CIG provides limited alternative egress but cannot absorb full displaced volumes.
Rockies Express
[FORCE MAJEURE] HAMILTON COMPRESSOR STATION FORCE MAJEURE
SEV 5/5
Force Majeure0.316 Bcf/dUntil Further Notice
Rockies Express declared a force majeure at Hamilton Compressor Station effective Gas Day May 19, 2026, cutting 0.316 Bcf/d of operating capacity across Segments 360, 370, and 380 until further notice. Primary firm, secondary firm, and AOR/ITS service classes are all at risk of curtailment. This event is independent of and additive to the prior scheduled maintenance under Notice ID 13721.
REX force majeure removes 0.316 Bcf/d of westbound capacity across three segments with all service classes at risk; combined with existing Notice 13721 maintenance cuts, expect bullish pressure on Appalachian and Midwest basis (Dominion South, TETCO M2, Chicago Citygate) as Marcellus/Utica westbound takeaway tightens.
Reroute: Moderate: Rover Pipeline, TETCO M2, and TCO serve overlapping Appalachian westbound markets and may absorb some displaced volumes, but the additive impact of concurrent REX maintenance (Notice 13721) reduces available spare capacity on alternative routes.
Rockies Express
[OPERATIONAL ALERT] BERTRAND COMPRESSOR STATION OPERATIONAL ISSUE - UPDATE #13
SEV 5/5
Compressor Issue1.118 Bcf/dUntil Further Notice
Rockies Express Bertrand Compressor Station is restricting Segment 250 westbound-to-eastbound (West to East) capacity to 1.118 Bcf/d until further notice, effective Gas Day May 1, 2026. This is Update #13, indicating a prolonged unresolved operational issue with no restoration timeline. Primary firm, secondary firm, and interruptible service are all at risk of not being scheduled, indicating curtailments across all service classes.
REX Segment 250 restricted to 1.118 Bcf/d W-to-E with primary and secondary firm at risk; expect bearish pressure at Rockies basin hubs (CIG, Cheyenne) as eastbound takeaway is curtailed and bullish pressure at Midcontinent and Chicago Citygate basis points versus Henry Hub -- no restoration timeline adds further upside risk to downstream markets.
Reroute: None: Trailblazer Pipeline leases capacity at Bertrand Compressor Station on REX -- a Bertrand CS constraint simultaneously affects Trailblazer, eliminating it as an independent reroute option. CIG provides some Rockies egress southward but cannot replicate REX eastbound volumes into the Midcontinent.
Tallgrass Energy
[Trailblazer Pipeline (TPC)] [FORCE MAJEURE] REDTAIL COMPRESSOR STATION FORCE MAJEURE
SEV 5/5
Force Majeure0.030 Bcf/dUntil Further Notice
Trailblazer Pipeline declared force majeure at Redtail Compressor Station effective Gas Day April 15, 2026, reducing operating capacity to only 30 MDth/d (0.030 Bcf/d) until further notice. Primary firm, secondary firm, and interruptible service are all at risk of curtailment. No restoration timeline has been provided; end date is listed as 12/31/9000, indicating an indefinite outage.
Trailblazer FM at Redtail CS cuts operating capacity to 0.030 Bcf/d with all service classes at risk; this effectively eliminates Trailblazer as a functional eastbound Rockies takeaway path, expect bearish pressure on CIG/Cheyenne Hub Rockies basis as gas backs up in the Rockies, with offsetting bullish pressure at Midcontinent and Northern Natural Gas downstream delivery points.
Reroute: None: Trailblazer leases capacity at Bertrand CS on REX, and REX Zone 1 is the primary correlated alternative -- when Trailblazer is constrained at a compressor station upstream of Bertrand, REX may face correlated pressure; Colorado Interstate Gas (CIG) provides a partial alternative for some Rockies volumes moving south, but cannot fully absorb Trailblazer's eastbound capacity.
Rockies Express
[OPERATIONAL ALERT] BERTRAND COMPRESSOR STATION OPERATIONAL ISSUE - UPDATE #11
SEV 5/5
Compressor Issue1.103 Bcf/dUntil Further Notice
Rockies Express Pipeline has restricted capacity on Segment 250 (West-to-East direction) to 1,103 MDth/d (1.103 Bcf/d) effective March 31, 2026, until further notice due to an ongoing operational issue at Bertrand Compressor Station. This is Update #11, indicating a prolonged unresolved outage. Primary firm, secondary firm, and interruptible service (ITS/AOR) are all at risk of not being scheduled, meaning even firm shippers face potential curtailments with no restoration timeline provided.
REX Segment 250 restriction to 1.103 Bcf/d with all service classes including primary firm at risk tightens Rockies-to-Midcontinent eastbound takeaway; expect bearish pressure at CIG and Opal as Rockies basin gas backs up, with bullish signals at Midcontinent and REX Zone 3 downstream delivery points -- Trailblazer is NOT an independent reroute as it shares Bertrand CS.
Reroute: None: Trailblazer Pipeline leases capacity at Bertrand Compressor Station on REX and is simultaneously constrained by the same facility failure -- these are not independent reroute options. No viable alternative exists for affected West-to-East REX volumes.

[Trailblazer Pipeline (TPC)] [OPERATIONAL ALERT] THIRD PARTY OPERATIONAL ISSUE - BERTRAND COMPRESSOR STATION - UPDATE #10
SEV 5/5
Compressor Issue0.813 Bcf/dUntil Further Notice
Trailblazer Pipeline Segment 20 is restricted to 0.813 Bcf/d effective March 30, 2026 gas day due to a third-party operational issue at Bertrand Compressor Station, and the restriction continues until further notice. Primary firm, secondary firm, and interruptible service are all at risk of curtailment. This is Update #10, indicating an ongoing, unresolved multi-day constraint with no restoration timeline.
Trailblazer Segment 20 restricted to 0.813 Bcf/d with primary and secondary firm at risk; because Trailblazer shares Bertrand CS with REX, both pipes are simultaneously constrained -- expect bearish pressure on Rockies/CIG basis as gas backs up in the basin, with bullish pressure at Midcontinent and Chicago Citygate as eastbound takeaway remains curtailed until further notice.
Reroute: None: REX and Trailblazer share Bertrand Compressor Station -- both are simultaneously constrained by the same third-party facility, eliminating any independent reroute option for eastbound Rockies volumes.
Rockies Express
[OPERATIONAL ALERT] BERTRAND COMPRESSOR STATION OPERATIONAL ISSUE - UPDATE #10
SEV 5/5
Compressor Issue1.174 Bcf/dUntil Further Notice
Bertrand Compressor Station on REX Segment 250 remains operationally impaired, restricting eastbound capacity to 1.174 Bcf/d until further notice. Primary firm, secondary firm, and interruptible service are all at risk of not being scheduled -- a rare and serious escalation beyond interruptible-only curtailments. No restoration timeline has been provided.
REX Segment 250 eastbound restriction to 1.174 Bcf/d with primary firm service at risk signals severe Rockies takeaway constraint; expect bearish pressure at CIG/Cheyenne Hub as Rockies gas backs up, with bullish pressure at Midcontinent and Chicago Citygate as eastbound supply is reduced.
Reroute: None: Trailblazer Pipeline leases capacity at Bertrand Compressor Station on REX -- both pipes are simultaneously constrained by the same facility failure. No independent reroute exists for eastbound Rockies volumes.

[Trailblazer Pipeline (TPC)] [FORCE MAJEURE] THIRD PARTY FORCE MAJEURE - JULESBURG COMPRESSOR STATION
SEV 5/5
Force Majeure0.722 Bcf/dUntil Further Notice
A third-party force majeure at REX's Julesburg Compressor Station, effective Gas Day March 2, 2026, has reduced Trailblazer Segment 20 operating capacity to 722 MDth/d (0.722 Bcf/d) until further notice. Primary firm, secondary firm, and AOR/ITS service are all at risk of curtailment. This is Revision 3 and the force majeure remains active with no restoration timeline.
Active force majeure at the shared Julesburg/Bertrand CS facility constrains both REX and Trailblazer simultaneously to 0.722 Bcf/d on Segment 20 with no restoration timeline; expect bearish pressure on Rockies CIG/Cheyenne Hub basis as eastbound Rockies takeaway is severely curtailed with zero reroute alternative.
Reroute: None: REX and Trailblazer share the Julesburg/Bertrand Compressor Station -- this force majeure is at the shared facility, meaning both pipelines are constrained simultaneously. No independent reroute exists for Rockies eastbound volumes.
Rockies Express
[FORCE MAJEURE] JULESBURG COMPRESSOR STATION FORCE MAJEURE
SEV 5/5
Force Majeure1.045 Bcf/dUntil Further Notice
REX declared force majeure at Julesburg Compressor Station effective Gas Day March 2, 2026, reducing operating capacity through Segment 240 (west-to-east direction) to 1.045 Bcf/d until further notice. This is Revision 3 and the force majeure remains active with no restoration timeline; primary firm, secondary firm, and interruptible service are all at risk of curtailment. The end date of 12/31/9000 confirms an open-ended outage with no known resolution.
Active REX FM at Julesburg CS caps westbound-to-eastbound throughput on Segment 240 at 1.045 Bcf/d until further notice, with firm service curtailments confirmed at risk; expect bullish pressure on Midcontinent and Chicago Citygate basis as Rockies/DJ Basin gas loses eastbound takeaway, and bearish pressure at CIG/Cheyenne Hub as supply backs up in the basin.
Reroute: Limited: Trailblazer Pipeline (TPC) is the primary alternative for Rockies eastbound gas, but Trailblazer leases capacity at Bertrand CS on REX -- if the Julesburg FM affects shared infrastructure, Trailblazer reroute reliability is uncertain. CIG provides some alternative egress but does not serve the same downstream Midcontinent/Chicago markets.

[FORCE MAJEURE] FORCE MAJEURE - REMEDIATION - CS341-UPD2
SEV 4/5
Force MajeureUntil Further Notice1 Days
NGPL has declared force majeure at Compressor Station 341 (CS341) effective May 29, 2026 at 1:03 PM, with remediation expected through May 30, 2026 at 9:00 AM -- approximately 20 hours. No specific capacity volume is stated in the notice. CS341 is an NGPL system compressor station on the Gulf Coast-to-Chicago corridor; the outage constrains northbound throughput on one of the highest-capacity Midwest pipelines in the U.S.
NGPL force majeure at CS341 constrains Gulf Coast-to-Midwest throughput capacity for roughly 20 hours; expect bearish pressure at Henry Hub and Gulf Coast origin points as northbound takeaway is reduced, with corresponding bullish pressure at Chicago Citygate and NGPL Midcontinent basis.
Reroute: Moderate: ANR, PEPL, and TETCO serve overlapping Gulf Coast-to-Chicago/Midwest corridors and may absorb some displaced volumes, though NGPL is very high capacity and full offset is unlikely if the CS341 restriction is substantial.

[OPERATIONAL FLOW ORDER] SOC Declaration - System Wide Draft
SEV 4/5
Operational AlertUntil Further Notice1 Days
EPNG has declared a System-Wide Operational Flow Order (SOC Declaration) effective 05/27/2026 at 7:10 AM, running through 05/28/2026 at 9:00 AM -- approximately 26 hours. This is a system-wide draft OFO, meaning EPNG is calling on all shippers to manage linepack and nominations across the entire pipeline. No specific capacity volume is stated in the notice.
EPNG system-wide SOC OFO signals pipeline stress across the full Permian-to-SoCal/Arizona corridor; expect bearish pressure at Waha as gas is trapped in the basin and bullish pressure at SoCal Border and Arizona delivery points as westbound supply tightens through 05/28 9:00 AM.
Reroute: Moderate: Transwestern Pipeline (TW) is the primary competing pipeline for SoCal border deliveries and may absorb some diverted volumes, but spare capacity on TW is typically limited during system stress events; partial reroute only.

[FORCE MAJEURE] FORCE MAJEURE-COMP STA 168 UPD2
SEV 4/5
Force MajeureUntil Further Notice1 Days
NGPL has declared a force majeure at Compressor Station 168, effective 05/20/2026 at 1:10 PM with an end date of 05/21/2026 at 9:00 AM. CS 168 is a key compression point on NGPL's Gulf Coast-to-Chicago corridor, and the force majeure indicates an unplanned outage. No specific capacity volume is stated in the notice, but NGPL is one of the highest-throughput Midwest pipelines and any CS 168 constraint materially affects northbound flows.
NGPL force majeure at CS 168 restricts northbound Gulf Coast takeaway capacity, expect bearish pressure at Henry Hub and NGPL Texas as gas backs up on the Gulf Coast, with bullish pressure at Chicago Citygate and NGPL Midcontinent basis versus Henry Hub through 05/21 morning.
Reroute: Moderate: ANR, PEPL, and REX Zone 3 serve overlapping Chicago and Midwest markets, but NGPL is very high capacity and partial reroute through these alternatives is unlikely to fully offset the constraint during the affected window.

[FORCE MAJEURE] Force Majeure – Line 2215 – Line Damage
SEV 4/5
Force MajeureUntil Further Notice1 Days
EPNG has declared a force majeure on Line 2215 due to line damage, effective 05/15/2026 at 11:16 AM with an expected end date of 05/16/2026 at 9:00 AM -- approximately 22 hours of constraint. No specific capacity volume was provided in the notice. Line 2215 is an EPNG mainline segment carrying Permian Basin gas westbound toward SoCal and Arizona delivery points.
EPNG force majeure on Line 2215 produces a split signal: bearish pressure at Waha as Permian Basin takeaway is curtailed, with bullish pressure at SoCal Border and Arizona delivery points as westbound supply is reduced; no capacity volume stated but even partial EPNG mainline damage warrants immediate attention given typical segment throughput.
Reroute: Moderate: Transwestern Pipeline (TW) is the primary competing pipeline for SoCal border deliveries and can absorb some displaced EPNG volumes, though TW may lack sufficient spare capacity to fully offset an EPNG mainline constraint depending on utilization levels at the time.

[FORCE MAJEURE] Force Majeure - Florida A
SEV 4/5
Force MajeureUntil Further Notice1 Days
El Paso Natural Gas declared force majeure on the Florida A segment effective 05/14/2026 at 1:34 PM, with an expected end date of 05/15/2026 at 9:00 AM -- approximately 19 hours of disruption. The Florida A segment is an internal EPNG tariff designation for a Southwest/Texas corridor outbound from the Permian Basin, not related to the state of Florida. No capacity volume was specified in the notice.
EPNG force majeure on the Florida A segment tightens Permian takeaway westward; expect bearish pressure at Waha as basin gas backs up and bullish pressure at SoCal Border and Arizona delivery points -- duration is short (~19 hours) but FM status warrants monitoring for extensions.
Reroute: Moderate: Transwestern Pipeline (TW) is the primary competing pipeline for SoCal border and Arizona deliveries and may absorb some displaced volumes, but spare capacity on TW is not confirmed and a simultaneous TW constraint would eliminate California reroute options entirely.

[FORCE MAJEURE] Force Majeure - Amarillo Station Unit 1
SEV 4/5
Force MajeureUntil Further Notice1 Days
El Paso Natural Gas has declared a force majeure at Amarillo Station Unit 1, effective 05/11/2026 at 8:16 AM with an expected restoration by 05/12/2026 at 9:00 AM. The Amarillo Station is a compressor facility on EPNG's mainline in the Texas Panhandle/New Mexico corridor, a key segment for moving Permian Basin gas westward toward SoCal and Arizona delivery points. No specific capacity loss volume was stated in the notice.
EPNG force majeure at Amarillo Station Unit 1 tightens westbound Permian takeaway for approximately one day; expect bearish pressure at Waha as basin gas backs up and bullish pressure at SoCal Border and Arizona delivery points due to reduced westbound supply.
Reroute: Moderate: Transwestern Pipeline (TW) serves overlapping SoCal Border and Arizona markets as the primary competing westbound alternative, but may lack sufficient spare capacity to fully absorb EPNG Amarillo-constrained volumes for the affected period.

[FORCE MAJEURE] FORCE MAJEURE-REMEDIATION-CS341-UPD1
SEV 4/5
Force MajeureUntil Further Notice54 Days
NGPL has declared a force majeure at Compressor Station 341, effective 05/07/2026 with a stated end date of 06/30/2026. The notice is a first revision (Revision 1, Is Revision: No) and references remediation activity at CS341, suggesting an unplanned equipment failure or integrity issue requiring extended repair. No specific capacity volume is stated in the notice text.
NGPL CS341 force majeure reduces Gulf Coast-to-Midwest takeaway capacity on one of the highest-throughput Midwest pipelines; expect bearish pressure at Henry Hub and Gulf Coast origin points as gas backs up, with bullish basis widening at Chicago Citygate and NGPL Midcontinent -- no capacity figure provided to size the impact.
Reroute: Moderate: ANR, PEPL, and REX Zone 3 serve overlapping Gulf Coast-to-Chicago corridors and may absorb some displaced volumes, but NGPL is very high capacity and a large constraint is difficult to fully offset on alternative pipes.
Enable Gas Transmission (EGT)
[Enable Gas Transmission (EGT)] [Force Majeure] ALLEN COMPRESSOR FMJ
SEV 4/5
Force MajeureUntil Further Notice
Enable Gas Transmission has declared force majeure at Allen Compressor Station in Hughes County, Oklahoma, effective May 6, 2026, with no end date. The event affects EGT's West 2 Pooling Area, where primary firm nominations are expected to be scheduled at only 80-90% of MRO quantities until further notice. Nominations in the impacted area are being locked each Evening Cycle for the duration of the outage.
EGT force majeure on Allen CS curtails primary firm service to 80-90% of MRO in the West 2 Pooling Area with no restoration timeline, creating bearish pressure on Arkla Basin and Oklahoma basis as EGT volumes back up at the receipt pool with limited egress alternatives.
Reroute: Moderate: Gulf South and Southern Natural (EGT via Energy Transfer) serve overlapping Arkla Basin and Southeast corridors, but reroute depends on available capacity at interconnects downstream of the West 2 Pooling Area and may not fully absorb curtailed primary firm volumes.

[Trailblazer Pipeline (TPC)] [OPERATIONAL ALERT] THIRD PARTY OPERATIONAL ISSUE - BERTRAND COMPRESSOR STATION - UPDATE #13
SEV 4/5
Compressor Issue0.819 Bcf/dUntil Further Notice
Trailblazer Pipeline Segment 20 capacity is restricted to 0.819 Bcf/d effective Gas Day May 1, 2026, until further notice, due to an ongoing third-party operational issue at Bertrand Compressor Station (Update #13). This is the 13th update on a continuing event with no restoration timeline. Primary firm, secondary firm, and interruptible service are all at risk of not being scheduled, indicating the constraint is severe enough to threaten firm service.
Trailblazer Segment 20 restricted to 0.819 Bcf/d with firm service at risk; given REX and Trailblazer share Bertrand CS, this constraint simultaneously limits both pipes -- expect bearish pressure at Rockies/CIG basis with no viable reroute for affected volumes.
Reroute: None: REX and Trailblazer share Bertrand Compressor Station -- both pipelines are simultaneously constrained by the same third-party facility, eliminating any independent reroute option for Rockies eastbound volumes.

[FORCE MAJEURE] FORCE MAJEURE-COMP STA 168 UPD1
SEV 4/5
Force MajeureUntil Further Notice67 Days
NGPL has declared force majeure at Compressor Station 168, effective April 24, 2026, with an end date of June 30, 2026. CS 168 is a key compression facility on the NGPL mainline moving Gulf Coast and Midcontinent gas northward into Chicago and Midwest markets. No specific capacity volume is stated in the notice.
NGPL CS 168 force majeure constrains northbound Gulf Coast-to-Midwest throughput for up to 67 days; expect bearish pressure at Henry Hub as Gulf Coast gas backs up, with bullish pressure at Chicago Citygate and NGPL Midcontinent basis vs Henry Hub.
Reroute: Moderate: ANR, PEPL, and REX Zone 3 serve overlapping Chicago and Midwest markets and may absorb some displaced NGPL volumes, though NGPL is very high capacity and a large constraint is difficult to fully offset on alternative pipes.
Enable Gas Transmission (EGT)
[Enable Gas Transmission (EGT)] [Force Majeure] DELHI COMPRESSOR FMJ
SEV 4/5
Force MajeureUntil Further Notice
Enable Gas Transmission has declared force majeure at its Delhi Compressor Station in Richland Parish, Louisiana, effective April 8, 2026, continuing until further notice. The unplanned outage prevents deliveries to Gulf Run Delhi Core Delivery Point (#291856) and is expected to impact primary firm transportation services in EGT's South Pooling Area. No restoration timeline has been provided.
EGT force majeure at Delhi CS eliminates deliveries to Gulf Run Delhi Core Del with no end date, curtailing primary firm service in the South Pooling Area; expect bearish pressure on Arkla Basin and Gulf Coast basis as stranded gas backs up, with watch on Gulf Run LNG feed gas supply chain if downstream volumes are affected.
Reroute: Moderate: Gulf South and Southern Natural (EGT/Energy Transfer) serve overlapping Gulf Coast and Haynesville-area corridors, providing partial alternatives; however, the specific Gulf Run Delhi Core delivery point has no direct bypass, and volumes destined for Gulf Run interconnects (including LNG feed gas paths) cannot be fully replaced via alternate routing.
Enable Gas Transmission (EGT)
[Enable Gas Transmission (EGT)] [Force Majeure] DELHI COMPRESSOR FMJ TERM
SEV 4/5
Force MajeureUntil Further Notice
EGT declared force majeure at its Delhi Compressor Station in Richland Parish, Louisiana, effective April 12, 2026, with no end date (until further notice). The outage prevents EGT from delivering to Gulf Run Delhi Core Delivery Point (#291856), with primary firm transport service expected to be impacted. A separate balancing alert (6327) has been terminated as of April 12, indicating the operational situation may be stabilizing, but the FM itself remains active.
EGT force majeure at Delhi CS cuts primary firm deliveries to Gulf Run Delhi with no restoration timeline; expect localized tightness at the Gulf Run interconnect and potential knock-on effects for Haynesville production takeaway and LNG feed gas nominations at Gulf Coast export terminals supplied via Gulf Run.
Reroute: Moderate: Gulf South Pipeline and Kinder Morgan assets serve overlapping Haynesville corridor routes, and some volumes may be redirected away from the Gulf Run Delhi delivery point; however, the specific impact on LNG feed gas supply depends on whether downstream shippers can nominate alternate paths to Gulf Coast export terminals.
EGTS
OFO: Northern Area Conform Services
SEV 4/5
Operational AlertUntil Further Notice
EGTS has issued an Operational Flow Order (OFO) for Conform Services on its Northern Area, effective January 23, 2026 at 15:00. This is a Critical-category notice indicating active system stress requiring shippers to conform nominations to actual usage. No specific capacity volume is stated, but OFO declarations on EGTS Northern Area signal tightness in Appalachian Mid-Atlantic supply flows. Duration is indeterminate from this notice.
EGTS Northern Area OFO signals active system stress on the Appalachian/Mid-Atlantic corridor; expect bullish pressure at Dominion South and TETCO M2 basis with potential tightening at Mid-Atlantic delivery points served by EGTS and Transco Zone 5.
Reroute: Moderate: TCO (Columbia Gas Transmission) and Equitrans serve overlapping Appalachian markets and may absorb some volumes, but EGTS Northern Area OFOs during winter typically reflect system-wide tightness that limits available reroute capacity on competing pipes.
ANR Pipeline (TC Energy)
CAPACITY REDUCTION - Southeast Area – Eunice Compressor Station
SEV 4/5
Maintenance1.611 Bcf/dUntil Further Notice2 Days
ANR Pipeline has planned maintenance at Eunice Compressor Station in the Southeast Area on 3/18-3/19, resulting in curtailments across eight interconnect locations totaling approximately 1.611 Bcf/d of reduced capacity. Affected locations include major interconnects with TGP (443 MMcf/d reduced to 30 MMcf/d), Sonat/SNG (377 MMcf/d reduced to 110 MMcf/d), Weeks Island/LIG (270 MMcf/d reduced to 40 MMcf/d), and Col Gulf (143 MMcf/d reduced to 0 MMcf/d). ANR explicitly anticipates Firm Primary, Firm Secondary, and Interruptible curtailments, meaning all service classes are at risk.
ANR Eunice CS planned outage removes approximately 1.611 Bcf/d of Southeast Area capacity for 3/18-3/19, with firm primary curtailments explicitly anticipated; expect tightening at Transco Zone 4, SNG/Sonat, and TGP Southeast interconnects, with bullish basis pressure across Gulf Coast-to-Southeast delivery corridors.
Reroute: Limited: the Eunice CS constraint simultaneously affects ANR interconnects with both SNG/Sonat and TGP -- the two primary competing Southeast pipelines -- reducing the ability of shippers to reroute curtailed volumes; TETCO and CGT provide partial Gulf Coast northbound alternatives but are unlikely to absorb the full 1.6 Bcf/d reduction.
El Paso (EPNG)
[FORCE MAJEURE] Force Majeure - El Paso C Station
SEV 4/5
Force MajeureUntil Further Notice1 Days
EPNG has declared force majeure at El Paso C Station effective 04/15/2026 at 10:30 AM, with restoration expected by 04/16/2026 at 9:00 AM. El Paso C Station is a compressor station on the EPNG mainline in the El Paso/West Texas corridor, a key segment for westbound Permian Basin takeaway toward SoCal and Arizona. Duration is approximately 22.5 hours. No capacity volume is specified in the notice.
EPNG force majeure at El Paso C Station reduces westbound Permian takeaway capacity; expect bearish pressure at Waha as basin gas backs up and bullish pressure at SoCal Border and Arizona delivery points, though the short ~1-day duration limits sustained market impact.
Reroute: Moderate: Transwestern Pipeline (TW) serves overlapping SoCal Border and Arizona markets and is the primary reroute alternative; however, TW spare capacity at any given time may not fully absorb constrained EPNG volumes, particularly on short notice.

Trailblazer Pipeline Segment 20 capacity is restricted to 0.813 Bcf/d effective evening cycle April 1, 2026, until further notice due to a third-party operational issue at Bertrand Compressor Station. This is Update #12, indicating an ongoing multi-revision unresolved outage. Primary firm, secondary firm, and interruptible service are all at risk of curtailment. No restoration timeline has been provided.
Trailblazer Segment 20 restricted to 0.813 Bcf/d with primary firm at risk and no restoration timeline; simultaneous REX/Trailblazer Bertrand CS constraint removes independent reroute options, bearish pressure on Rockies/CIG basis as eastbound Rockies gas remains stranded with no alternative takeaway.
Reroute: None: REX and Trailblazer share Bertrand Compressor Station -- both pipelines are simultaneously constrained by the same third-party facility, meaning REX cannot serve as an independent reroute for Trailblazer volumes affected at Bertrand CS.

[OPERATIONAL ALERT] BERTRAND COMPRESSOR STATION OPERATIONAL ISSUE - UPDATE #12
SEV 4/5
Compressor Issue1.174 Bcf/dUntil Further Notice
Rockies Express Pipeline is restricting Segment 250 (Zone 1, West-to-East direction) to 1,174 MDth/d (1.174 Bcf/d) due to an ongoing operational issue at Bertrand Compressor Station, effective evening cycle April 1, 2026, until further notice. This is Update #12, indicating a prolonged unresolved event. Primary firm, secondary firm, and interruptible service are all at risk of curtailment at this capacity level.
Bertrand CS constraint caps REX Zone 1 eastbound at 1.174 Bcf/d until further notice, with all service classes at curtailment risk; Trailblazer shares this facility and is simultaneously constrained, leaving zero independent reroute -- expect bearish Rockies basis pressure and bullish Midcontinent/Chicago Citygate basis widening vs Henry Hub.
Reroute: None: REX and Trailblazer share Bertrand Compressor Station -- both are simultaneously constrained by the same facility, and no independent reroute exists for Rockies eastbound volumes affected by this outage.

[Trailblazer Pipeline (TPC)] [OPERATIONAL ALERT] THIRD PARTY OPERATIONAL ISSUE - BERTRAND COMPRESSOR STATION - UPDATE #11
SEV 4/5
Compressor Issue0.764 Bcf/dUntil Further Notice
Trailblazer Pipeline Segment 20 is restricted to 0.764 Bcf/d effective March 31, 2026 ID2 cycle and continuing until further notice due to a third-party operational issue at Bertrand Compressor Station. This is Update #11, indicating a prolonged unresolved outage with no restoration timeline. Primary firm, secondary firm, and interruptible service are all at risk of curtailment.
Bertrand CS restriction caps Trailblazer Segment 20 at 0.764 Bcf/d with firm service at risk; because REX also shares Bertrand CS, reroute is effectively unavailable, placing bearish pressure on Rockies basin basis (CIG/Cheyenne) with no meaningful eastbound relief valve until Bertrand is restored.
Reroute: None: Trailblazer and REX share Bertrand Compressor Station -- both are simultaneously constrained by the same third-party facility, making REX a non-viable reroute option for affected Trailblazer volumes.
Algonquin Gas Transmission
03/18/2026- AGT Hourly Customer Specific Operational Flow Order
SEV 4/5
Operational AlertUntil Further Notice
Algonquin Gas Transmission has issued a system-wide Hourly Customer Specific Operational Flow Order (OFO) effective March 18, 2026, and continuing until further notice (notice end date listed as June 16, 2026). The OFO imposes a No Deficiency Point constraint of 25%/250 on an hourly basis for all customers system-wide, indicating active system stress requiring shippers to maintain balanced or surplus positions on an intra-day basis. No specific capacity volume is stated, but the 'until further notice' language and system-wide scope signal an unresolved operational constraint.
Algonquin system-wide Hourly OFO active from March 18 with no firm restoration date -- expect significant bullish pressure at Algonquin Citygate and broader New England basis as shippers scramble to comply with hourly balancing requirements, with heightened spike risk given no reroute alternative exists for core New England deliveries.
Reroute: Limited to none: Algonquin and Iroquois are the two primary pipelines serving New England; Iroquois is not reported constrained at this time but cannot absorb full Algonquin system shortfall. No meaningful reroute exists for the core New England LDC market.
Northern Border Pipeline (NBPL)
Northern Border Low Inventory OFO
SEV 4/5
Operational AlertUntil Further Notice
Northern Border Pipeline has issued an active OFO effective immediately and until further notice due to low system inventory and linepack concerns driven by sustained cold weather. Shippers are required to stay within 5% or 25,000 Dth/day of posted nominations, with NBPL reserving the right to impose prorated meter capacity restrictions. The OFO was originally posted January 20, 2026 and this revision (Rev 3) confirms the OFO remains in effect through at least January 30, 2026.
Active NBPL OFO with no-notice curtailment authority and an 'until further notice' posture tightens Canadian gas flows into the Chicago/Midwest corridor, supporting bullish basis pressure at Chicago Citygate and NGPL Midcontinent vs Henry Hub.
Reroute: Limited: Alliance Pipeline provides an alternative Canadian border crossing into Chicago, but Alliance volumes are typically fully subscribed, especially during cold weather events, limiting meaningful displacement of constrained NBPL capacity.
Northern Border Pipeline (NBPL)
UPDATE: OFO - Under Performance, Effective ID1 Gas Day January 21
SEV 4/5
Operational Alert0.740 Bcf/dUntil Further Notice
NBPL has issued a Revision 3 OFO for under-performance, active since January 21, 2026 and continuing until further notice. Receipt capacity at Stateline is capped at 100,000 MMBtu/d and Spring Creek at 640,000 MMBtu/d, combining for approximately 0.740 Bcf/d of constrained Canadian border receipt capacity. This revision escalates prior capacity limits (Stateline was 50,000 and Spring Creek was 600,000 in the Timely cycle) and the OFO remains active with no restoration timeline, indicating ongoing supply under-delivery from the Canadian side.
Active NBPL OFO with 0.740 Bcf/d of combined border receipt capacity constrained until further notice tightens Canadian gas imports into the Midwest; expect bullish pressure at Chicago Citygate and NGPL Midcontinent basis versus Henry Hub with no defined restoration date amplifying the signal.
Reroute: Limited: Alliance Pipeline provides an alternative Canadian import corridor into Chicago but is typically fully subscribed; partial mitigation is possible but NBPL volumes cannot be fully replaced, leaving Midwest markets structurally short on Canadian supply.
El Paso (EPNG)
[FORCE MAJEURE] Force Majeure – Casa Grande C Station
SEV 4/5
Force MajeureUntil Further Notice1 Days
EPNG has declared force majeure at Casa Grande C Compressor Station, effective 03/17/2026 at 11:41 AM with an expected restoration by 03/18/2026 at 9:00 AM. Casa Grande is located in Arizona on EPNG's westbound mainline, meaning this constraint affects gas movement from the Permian/Waha origin area toward SoCal Border and Arizona delivery points. No specific capacity volume was stated in the notice. Duration is approximately one day.
EPNG force majeure at Casa Grande C Station restricts westbound flow on the Permian-to-SoCal/Arizona corridor; expect bearish pressure at Waha as basin gas backs up and bullish pressure at SoCal Border and Arizona delivery points for the next ~22 hours.
Reroute: Moderate: Transwestern Pipeline (TW) is the primary competing westbound pipeline serving SoCal Border and Arizona markets and may absorb some displaced volumes, though available spare capacity on TW will determine how fully the constraint can be offset.

[Gulf Run Transmission] [Force Maj] CGT GR FMJ
SEV 4/5
Force MajeureUntil Further Notice
Gulf Run Transmission has declared a Force Majeure at the CGT GR Meter Station (#13548) in Richland Parish, Louisiana (Zone 1), effective January 28, 2026. Nominations at this interconnect have been reduced to EPSQ (Equivalent Prior Scheduling Quantity) with no restoration timeline provided. The event is open-ended ('until further notice') and affects a key interconnect between Gulf Run and Columbia Gulf Transmission, a primary Haynesville-to-Gulf Coast backhaul route.
Gulf Run force majeure on the CGT GR interconnect removes an indeterminate volume of Haynesville supply from the Columbia Gulf Transmission corridor with no restoration timeline; expect modest bullish pressure at Henry Hub and Transco Zone 4 until flow restoration is confirmed.
Reroute: Moderate: Gulf South Pipeline and Kinder Morgan assets serve overlapping Haynesville Basin corridors and may absorb some displaced volumes, but the specific CGT interconnect serves a unique routing path and full reroute is uncertain without knowing the affected volume.

[Gulf Run Transmission] [Force Maj] CGT GR FMJ Update
SEV 4/5
Force Majeure0.200 Bcf/dUntil Further Notice62 Days
Gulf Run Transmission declared force majeure at the CGT GR meter station (#13548) in Richland Parish, Louisiana (Zone 1), effective January 29, 2026. Nominations at this interconnect are restricted to 200,000 MMBtu/day (0.200 Bcf/d), superseding the prior total shutdown under Notice #60993. The restriction runs through April 1, 2026, approximately 62 days, though the pipeline retains 'until further notice' language for updates.
Gulf Run FM at CGT GR limits Zone 1 throughput to 0.200 Bcf/d, curtailing Haynesville-origin gas moving toward Columbia Gulf Transmission and downstream Southeast/LNG markets; expect bearish Henry Hub and Haynesville basis pressure as supply backs up, with modest bullish signal at Transco Zone 4 and CGT downstream delivery points.
Reroute: Moderate: Gulf South and Kinder Morgan assets serve overlapping Haynesville corridors and could absorb some diverted volumes, but CGT GR is a key interconnect for moving Gulf Run Zone 1 gas into the Columbia Gulf northbound system; full offset is unlikely given the scale of the restriction.
Energy Transfer
[Gulf Run Transmission] [Force Maj] CGT GR FMJ Update #2
SEV 4/5
Force Majeure0.520 Bcf/dUntil Further Notice
Gulf Run Transmission declared force majeure at its CGT GR meter station (#13548) in Richland Parish, Louisiana (Zone 1), initially cutting nominations to zero, then to 200,000 MMBtu/d, and as of January 29 partially restoring to a cap of 520,000 MMBtu/d effective January 30. The end date is listed as April 1, 2026, but the notice states it remains in effect until further notice. This interconnect is a key Haynesville production outlet into Columbia Gulf Transmission, and the restriction limits approximately 0.52 Bcf/d of northbound Gulf Coast flow capacity.
Gulf Run FM caps CGT GR nominations at 0.52 Bcf/d with no firm restoration timeline, tightening Haynesville takeaway and supporting Henry Hub and Transco Zone 4 basis as supply that would otherwise flow north via CGT is constrained.
Reroute: Moderate: Gulf South and other Kinder Morgan Haynesville-area assets serve overlapping corridors, but Gulf Run is a dedicated high-capacity Haynesville egress pipe and partial reroute may not fully absorb the constrained volumes at CGT GR.

[Enable Mississippi River Transmission] [Force Maj] East Line FMJ
SEV 4/5
Force MajeureUntil Further Notice
Enable Mississippi River Transmission has declared force majeure on its East Line due to unplanned maintenance at STL Chain of Rocks (MP 100007) in St. Louis County, Missouri, effective January 21, 2026, with no restoration timeline given. Nominations at the STL Chain of Rocks delivery/receipt point will not be scheduled for the duration. MRT acknowledges firm service impacts are anticipated based on current nominations.
MRT force majeure on East Line removes a key Arkansas/Missouri delivery point with no restoration timeline and confirmed firm service impacts; expect tightening of MRT-served local distribution markets in AR/MO with limited reroute alternatives.
Reroute: Limited: MRT serves specific local markets in Arkansas and Missouri with few pipeline alternatives; ANR and Gulf South provide some overlapping supply paths but cannot fully replace MRT East Line deliveries into St. Louis County-area points.

[Trailblazer Pipeline (TPC)] [OPERATIONAL ALERT] THIRD PARTY OPERATIONAL ISSUE - BERTRAND COMPRESSOR STATION - UPDATE #7
SEV 4/5
Operational Alert0.810 Bcf/dUntil Further Notice
Trailblazer Pipeline Segment 20 capacity is restricted to 0.810 Bcf/d effective January 1, 2026 and until further notice due to a third-party operational issue at Bertrand Compressor Station. This is Update #7 (Revision 3), indicating the constraint has been ongoing since at least late December 2025 with no restoration timeline. Primary firm, secondary firm, and interruptible service quantities are all explicitly at risk of not being scheduled.
Escalation trigger present: firm service curtailment risk explicitly stated and 'until further notice' timeline active -- Trailblazer restricted to 0.810 Bcf/d at Bertrand CS tightens Rockies eastbound takeaway; expect bearish pressure at CIG/Cheyenne Hub as basin gas backs up, with REX simultaneously constrained at the shared Bertrand CS facility eliminating any independent reroute.
Reroute: None: REX and Trailblazer share Bertrand Compressor Station -- both pipelines are simultaneously constrained by the same third-party facility, meaning REX cannot serve as an independent reroute for Trailblazer volumes affected at this location.

[Trailblazer Pipeline (TPC)] [OPERATIONAL ALERT] THIRD PARTY OPERATIONAL ISSUE - CHEYENNE COMPRESSOR STATION
SEV 4/5
Compressor Issue0.674 Bcf/dUntil Further Notice
On January 20, 2026, REX experienced an operational issue at its Cheyenne Compressor Station, which directly impacts Trailblazer Pipeline's leased capacity on Segment 10. Effective January 20-21, 2026 and until further notice, Segment 10 operating capacity is reduced to 0.674 Bcf/d ratable. Primary firm, secondary firm, and interruptible service are all at risk of not being scheduled.
Trailblazer Segment 10 constrained to 0.674 Bcf/d until further notice with primary and secondary firm service at risk; expect bearish pressure on Rockies basis (CIG/Cheyenne Hub) as eastbound takeaway is curtailed, with limited Midcontinent supply relief downstream.
Reroute: None: Trailblazer leases capacity at Cheyenne Compressor Station on REX -- the same facility causing this constraint. REX is simultaneously affected per notice ID 13346 on REX's EBB, meaning REX cannot serve as an independent reroute for affected Trailblazer volumes.

[OPERATIONAL ALERT] BERTRAND COMPRESSOR STATION OPERATIONAL ISSUE - UPDATE #7
SEV 4/5
Compressor Issue1.185 Bcf/dUntil Further Notice
Rockies Express Bertrand Compressor Station operational issue restricts Segment 250 West-to-East capacity to 1.185 Bcf/d until further notice, effective January 1, 2026. Primary firm, secondary firm, and interruptible service are all at risk of curtailment. This is Revision 3 of the notice but escalation triggers are present: capacity loss exceeds 500,000 MMBtu/day, firm service is explicitly at risk, and no restoration timeline exists.
REX Segment 250 restricted to 1.185 Bcf/d eastbound with primary and secondary firm at risk; expect bearish pressure at Rockies/CIG basis as gas backs up, with bullish pressure at Midcontinent and Chicago Citygate as eastbound Appalachian and Midcontinent supply tightens.
Reroute: None: Trailblazer Pipeline leases capacity at Bertrand Compressor Station on REX -- when REX Zone 1 is constrained at Bertrand, Trailblazer is simultaneously affected and cannot serve as an independent reroute option.

[OPERATIONAL ALERT] CHEYENNE COMPRESSOR STATION OPERATIONAL ISSUE
SEV 4/5
Compressor Issue0.985 Bcf/dUntil Further Notice
REX experienced an operational issue at Cheyenne Compressor Station on January 20, 2026, reducing eastbound capacity on Segment 200 to 0.985 Bcf/d until further notice. This is Revision 3 of the notice, but the end date remains open-ended with primary firm, secondary firm, and ITS/AOR quantities all at risk of curtailment. No restoration timeline has been provided.
REX Segment 200 eastbound capacity capped at 0.985 Bcf/d with firm service at risk and no restoration timeline; expect bullish pressure on Midcontinent and Chicago Citygate basis as Rockies gas is unable to move east, with mild bearish pressure on Rockies/CIG hub as supply backs up in the basin.
Reroute: Limited: Trailblazer Pipeline serves the same Rockies-to-Midcontinent eastbound corridor, but Trailblazer leases capacity at Bertrand CS on REX -- simultaneous constraints at Cheyenne CS and Bertrand CS are correlated and cannot be treated as independent reroutes. CIG provides some partial alternative for DJ Basin volumes but cannot replace REX Segment 200 eastbound throughput at scale.
