NOTICE OF FORCE MAJEURE ANRPL – Michigan Leg South – St. John Eastbound

SEV 4/5Force Majeure0.395 Bcf/d10 days

Summary

ANR Pipeline declared force majeure on its Michigan Leg South system effective October 3, 2026, due to an anomaly discovered between MLV 56 and MLV 57. Eastbound capacity at St. John (LOC #FPSTJNEB) is reduced by 395 MMcf/d (0.395 Bcf/d), leaving 930 MMcf/d available, with the constraint expected to run through October 12. ANR warns of firm primary (estimated 34% of contracted MDQ), firm secondary, and interruptible curtailments, with RCCs to be issued per Tariff Section 6.36 if primary firm scheduled quantities cannot be met.

Trading note

ANR force majeure removes 0.395 Bcf/d of eastbound Michigan Leg South capacity through Oct 12, with 34% of contracted firm primary MDQ at risk; expect bullish pressure on ANR ML 7 and Michigan/Wisconsin basis versus Henry Hub as Midwest supply tightens.

Reroute potential

Limited: TETCO (monitored), TGT (monitored), and PEPL (monitored) serve overlapping Gulf Coast-to-Midwest corridors but cannot fully replace Michigan-specific ANR Michigan Leg South deliveries; downstream Michigan LDC customers in particular have few practical bypass options.

Any reservation charge credits (RCCs) will be determined per the process set forth in the General Terms and Conditions, Section 6.36 of ANR's FERC Gas Tariff ("Tariff"). However, ANR will only issue RCCs if ANR is unable to schedule or deliver primary firm nominated capacity as a result of the outage. In the event RCCs are issued as set forth in the Tariff, shippers will receive RCCs based on its 7-day Force Majeure Average Usage Quantity, as defined in Section 6.36.2(a) of ANR's Tariff, less any scheduled quantities on the contract. By means of this notice, ANR is establishing which specific Gas Days will be included when determining a shipper's 7-day Force Majeure Average Usage Quantity pursuant to Section 6.36.2(a) of the Tariff.
