Line Segment 455 Operational Capacity Reduction -- Force Majeure Update (Supersedes #11238)

SEV 4/5Force Majeure0.205 Bcf/d14 days
Summary
Southern Star declared force majeure on Line Segment 455 due to a mechanical turbine failure at Saginaw Compressor Station in Jasper County, Missouri, effective October 9, 2026 (ID2 cycle). Capacity reductions total 205,000 Dth/d (0.205 Bcf/d): 180,000 Dth/d at Saginaw CS (Location ID 444550) and 25,000 Dth/d at Empire Energy Center (Location ID 378502). This notice (11240) supersedes 11238 and adds a repair timeline -- contractors are scheduled to complete turbine repairs by October 26, 2026, approximately two weeks from the notice date.
Trading note
Southern Star force majeure removes 0.205 Bcf/d of Midcontinent/Kansas-Missouri capacity through approximately October 26; expect mild bullish pressure on Southern Star basis and Kansas-Missouri delivery markets, with tightening most acute at points downstream of Saginaw CS -- live data shows Saginaw CS Area Deliveries (loc 444550) running at 83.9% utilization with only 16.1% headroom, consistent with the stated constraint.
Reroute potential
Moderate: ANR, PEPL, and Southern Natural (EGT) serve overlapping Midcontinent and Kansas-Missouri markets, though Southern Star serves specific local delivery points in Missouri that may have limited bypass. PEPL Princeton Receipt (loc 17131) is posting 74.5% utilization with 25.5% headroom, suggesting some alternative capacity exists.
