Rockies Express
[FORCE MAJEURE] HAMILTON COMPRESSOR STATION FORCE MAJEURE
SEV 5/5
Force Majeure
0.316 Bcf/d
Until 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.

[OPERATIONAL ALERT] BERTRAND COMPRESSOR STATION OPERATIONAL ISSUE - UPDATE #13
SEV 5/5
Compressor Issue
1.118 Bcf/d
Until 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.

[FORCE MAJEURE] FORCE MAJEURE - REMEDIATION - CS341-UPD2
SEV 4/5
Force Majeure
Until Further Notice
1 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 Alert
Until Further Notice
1 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 Majeure
Until Further Notice
1 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 Majeure
Until Further Notice
1 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 Majeure
Until Further Notice
1 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 Majeure
Until Further Notice
1 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 Majeure
Until Further Notice
54 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 Majeure
Until 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 Issue
0.819 Bcf/d
Until 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.
