SEV 4/5Force Majeure1.100 Bcf/d cut (capped at 1.100 Bcf/d)9 days
Summary
Transwestern Pipeline has declared a Force Majeure effective Gas Day October 24, 2026 due to a compressor station mechanical failure at Station 3 in Leupp, AZ. The Mainline Thoreau West System capacity is reduced to approximately 1.1 Bcf/d until further notice, with a currently stated end date of November 2, 2026. This is an unplanned event on a major westbound supply artery serving Arizona and California SoCal border markets.
Trading note
Transwestern FM at Station 3 (Leupp, AZ) caps Thoreau West System at 1.1 Bcf/d; expect bullish pressure at SoCal Border and Arizona delivery points as westbound capacity is constrained, while Permian/Waha and San Juan basin points face bearish pressure from backed-up supply -- no pre-event baseline available to quantify the net reduction from the stated 1.1 Bcf/d ceiling, and EPNG is the only partial reroute for California markets.
Reroute potential
Moderate: EPNG serves overlapping SoCal border and Arizona markets and is the primary competing pipeline; however, if EPNG is simultaneously constrained, California supply reroute drops to none. TW and EPNG together represent the two dominant westbound arteries from the Permian and San Juan basins.
