REVISED CAPACITY POSTING - TIM for August 14, 2026

SEV 4/5Force Majeure2.350 Bcf/dUntil further notice
Summary
CGT declares a Critical capacity constraint notice for August 14, 2026 reflecting an active force majeure at Corinth Compressor Station Unit 505 originally declared June 19, 2026, with no restoration date provided. CorinSEG is capped at 2.350 Bcf/d on the backhaul (net backhaul), and InvrnSEG is capped at 2.325 Bcf/d. A single point change from the prior posting restricts MidWestern Pipeline deliveries (Loc 4197) to 50,000 Dth/d effective ID1 for 8/13/2026. Due Shipper service is not available, indicating system tightness; no OFO has been declared.
Trading note
Active CGT force majeure limits CorinSEG backhaul to 2.350 Bcf/d and InvrnSEG to 2.325 Bcf/d on an unresolved 'until further notice' basis since June 19; Columbia Gulf mainline basis was -0.300 as of 2026-08-12 (5-day average -0.278 vs Henry Hub), and continued force majeure with no restoration timeline supports widening of Southeast delivery basis at Transco Zone 4 and TETCO M3 versus CGT mainline as northbound backhaul capacity remains constrained.
Reroute potential
Moderate: Texas Eastern (TETCO) and Trunkline (TGC) serve overlapping Gulf Coast northbound corridors and can absorb some volumes, but both are fully subscribed segments of a tight Gulf Coast system; the multi-month duration of this force majeure means alternative paths are likely already being utilized, limiting incremental reroute relief.
