Line Segment 455 Operational Capacity Reduction -- Force Majeure Update (Supersedes #11240)

SEV 4/5Force Majeure0.205 Bcf/d cut (capped at 0.180 Bcf/d)25 days
Summary
Southern Star has declared a force majeure at the Saginaw Compressor Station (Jasper County, MO) due to a mechanical failure of the Saginaw Turbine, reducing capacity by 180,000 Dth/d (0.180 Bcf/d) at Saginaw CS and 25,000 Dth/d (0.025 Bcf/d) at Empire Energy Center, totaling 0.205 Bcf/d. This update (superseding #11240) pushes the in-service date back to November 2, 2026, extending the outage that began ID2 cycle October 9. Live capacity data for Saginaw CS Area Deliveries (loc_id 444550) shows operating capacity at 0.180 Bcf/d with 0.143 Bcf/d scheduled, corroborating the reduced operating cap stated in the notice.
Trading note
Southern Star force majeure at Saginaw CS removes 0.205 Bcf/d of Midcontinent/Missouri delivery capacity through Nov 2; timeline extension is bearish for update direction but the sustained capacity loss is bullish for Southern Star basis -- watch for tightening in Kansas/Missouri LDC markets with limited reroute via ANR, PEPL, or Southern Star alternatives.
Reroute potential
Moderate: ANR and Panhandle Eastern (PEPL) serve overlapping Midcontinent and Midwest corridors and may absorb some volumes, but Southern Star serves specific Kansas/Missouri local markets that have limited direct bypass options.
