FORCE MAJEURE AT STA 542 EFF 8-25-26

SEV 4/5Force Majeure0.280 Bcf/dUntil further notice

Summary

Tennessee Gas Pipeline has declared a Force Majeure at Station 542 near DeKalb, Mississippi, effective August 25, 2026 and until further notice, after discovering a failure requiring immediate repairs on Unit 1. Units 2 and 3 at the same station have been out of service since March and April 2026 respectively, meaning all three compressor units are now offline simultaneously. Tennessee estimates the capacity impact at up to 0.280 Bcf/d, with Primary In the Path nominations on Segment 539 BH at risk of curtailment as early as the Timely Cycle for August 26, 2026.

Trading note

TGP force majeure at STA 542 removes up to 0.280 Bcf/d of northbound capacity on Segment 539 BH; with all three compressor units now offline and no restoration timeline, expect bullish pressure on Tennessee Zone 4/500 Leg basis vs Henry Hub -- Tennessee Zone 4-300 leg was already trading at a -1.360 basis vs HH as of 2026-08-24 and the loss of primary firm capacity eligibility beginning August 26 Timely Cycle could drive further widening in Southeast and downstream Northeast zones.

Reroute potential

Moderate: Southern Natural Gas (not live-monitored) and Gulf South serve overlapping Gulf Coast-to-Southeast corridors and may absorb some displaced volumes, though SNG real-time capacity is unverified and neither pipe fully replicates TGP's northbound reach into the Northeast.
