Update - Notice of Force Majeure Event - Unplanned Outage - Guillory M3681 Meter Station 2026

SEV 4/5Force Majeure5 days
Summary
Transco declared a Force Majeure event on 9/28/2026 due to integrity concerns on piping at the Guillory M3681 Meter Station (loc 9013263, Receipt, MP 473.5). The location was immediately restricted to zero scheduled capacity effective ID3 gas day 9/28/2026, with anticipated return to service October 3, 2026 -- a five-day outage. This is a revision superseding prior notice 17328542, with the key new information being the October 3 anticipated return-to-service date.
Trading note
Transco FM at Guillory M3681 receipt meter eliminates scheduling capacity at this Gulf Coast receipt point through October 2; live capacity data confirms 0 Bcf/d operating and scheduled at loc 9013263 (evening cycle 9/30), corroborating the outage, with bullish implications for Transco Zone 4 basis as Gulf Coast receipt supply is curtailed; no volume stated in the notice so system-wide impact depends on typical throughput at this meter.
Reroute potential
Limited to moderate: Transco is the dominant Southeast-to-Northeast pipeline and producers with access to alternative interconnects (Gulf South, CGT, TETCO) may be able to reroute volumes, but the specific meter restriction at Guillory M3681 eliminates that receipt point entirely for its contracted shippers.
