NOTICE OF FORCE MAJEURE ANR Pipeline Company – Southeast Area – Patterson Compressor Station

SEV 4/5Force Majeure1.403 Bcf/d10 days

Summary

ANR Pipeline has declared a Force Majeure at Patterson Compressor Station (Unit 1) in Jefferson Parish, Louisiana due to an unexpected equipment failure, effective September 25, 2026 through October 4, 2026. The outage reduces capacity across multiple interconnects including Shadyside/TGP (443 MMcf/d curtailed, leaving 30 MMcf/d), Weeks ISLA/LIG PL (260 MMcf/d curtailed), Patterson to Col Gulf (143 MMcf/d curtailed, leaving 0 MMcf/d), Shadyside/Sonat (281 MMcf/d curtailed), and others, totaling approximately 1.403 Bcf/d of combined capacity reductions across listed locations. ANR has flagged RCC eligibility per Tariff Section 6.36 if primary firm service cannot be scheduled.

Trading note

ANR Patterson FM removes approximately 1.403 Bcf/d of aggregate Gulf Coast northbound/interconnect capacity through Oct 4, with Patterson to Col Gulf reduced to zero and Shadyside/TGP slashed from ~473 to 30 MMcf/d; expect bullish pressure at ANR La. and Midwest delivery basis while Henry Hub and Gulf Coast onshore basis softens as northbound takeaway tightens.

Reroute potential

Moderate: TETCO (monitored), Trunkline/TGC (monitored), and CGT (monitored) serve overlapping Gulf Coast northbound corridors, but the scale of reductions across multiple interconnects -- particularly Patterson to Col Gulf zeroed out and Shadyside/TGP cut to 30 MMcf/d -- will stress available alternative capacity and may not fully offset firm service impacts.
