FORCE MAJEURE ON MUSKRAT EFF 10-9-26

SEV 4/5Force MajeureUntil further notice

Summary

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).

Trading note

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 potential

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.
