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

SEV 4/5Force Majeure0.395 Bcf/d cut (capped at 0.930 Bcf/d)29 days

Summary

ANR Pipeline has extended its Force Majeure at St. John Eastbound (LOC #FPSTJNEB) on the Michigan Leg South through October 31, 2026, pushed back from the prior end date of October 19. The FM was originally declared on October 3 due to an anomaly between MLV 56 and MLV 57, reducing eastbound capacity by 395 MMcf/d (0.395 Bcf/d), leaving 930 MMcf/d available. Firm Primary curtailments of approximately 34% of contracted MDQ remain in effect, with RCC eligibility active under ANR Tariff Section 6.36.

Trading note

ANR FM at St. John Eastbound removes 0.395 Bcf/d of Michigan Leg South eastbound capacity through Oct 31 (extended from Oct 19); live data shows 0.977 Bcf/d operating capacity with 0.642 Bcf/d scheduled on TD1 against the 0.930 Bcf/d post-FM ceiling, consistent with the stated constraint, and pre-event flow averaged ~0.67 Bcf/d (0.60-0.77 range) on TD1 -- the 0.930 Bcf/d cap sits above recent scheduled flow but well below normal operating capacity, with firm primary shippers taking a ~34% MDQ curtailment signaling real tightness at ANR ML 7 Michigan delivery points.

Reroute potential

Limited: TETCO, TGT, and PEPL serve overlapping Midwest/Michigan markets but ANR Michigan Leg South is a specific geographic corridor; partial reroute may be possible via TETCO or PEPL for some Michigan deliveries but full offset is unlikely given the firm primary curtailment level.

Notice Text
Since the last posting, ANR is extending the Force Majeure capacity constraint at St. John Eastbound (LOC #FPSTJNEB) through 10/31 (previously 10/19).

*Previous Posting*

This is to notify all contracted parties of ANR Pipeline Company ("ANR") that pursuant to Section 6.7 of ANR's FERC Gas Tariff, ANR has declared a Force Majeure event in effect for natural gas transactions in the Michigan Leg South area due to an anomaly discovered between MLV 56 & MLV 57. As a result, capacity will be reduced as follows: 

10/3 (Intraday) - 10/19  St. John Eastbound (LOC #FPSTJNEB) 395 MMcf/d (leaving 930 MMcf/d)

ANR anticipates this posting may result in Firm Primary, Firm Secondary and Interruptible curtailments. Estimated impact to Firm Primary as follows:

34% - Based on the Current Contracted MDQ

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.
