CAPACITY REDUCTION - Southeast Area – Eunice Compressor Station
SEV 4/5
Maintenance1.611 Bcf/dUntil Further Notice2 Days
ANR Pipeline has planned maintenance at Eunice Compressor Station in the Southeast Area on 3/18-3/19, resulting in curtailments across eight interconnect locations totaling approximately 1.611 Bcf/d of reduced capacity. Affected locations include major interconnects with TGP (443 MMcf/d reduced to 30 MMcf/d), Sonat/SNG (377 MMcf/d reduced to 110 MMcf/d), Weeks Island/LIG (270 MMcf/d reduced to 40 MMcf/d), and Col Gulf (143 MMcf/d reduced to 0 MMcf/d). ANR explicitly anticipates Firm Primary, Firm Secondary, and Interruptible curtailments, meaning all service classes are at risk.
ANR Eunice CS planned outage removes approximately 1.611 Bcf/d of Southeast Area capacity for 3/18-3/19, with firm primary curtailments explicitly anticipated; expect tightening at Transco Zone 4, SNG/Sonat, and TGP Southeast interconnects, with bullish basis pressure across Gulf Coast-to-Southeast delivery corridors.
Reroute: Limited: the Eunice CS constraint simultaneously affects ANR interconnects with both SNG/Sonat and TGP -- the two primary competing Southeast pipelines -- reducing the ability of shippers to reroute curtailed volumes; TETCO and CGT provide partial Gulf Coast northbound alternatives but are unlikely to absorb the full 1.6 Bcf/d reduction.

NOTICE OF FORCE MAJEURE ANRPL – Michigan Leg South – St. John Eastbound
SEV 4/5
Force Majeure0.395 Bcf/dUntil Further Notice10 Days
ANR Pipeline has declared force majeure on the Michigan Leg South segment due to an unexpected gas leak between MLV 56 and 57, reducing St. John Eastbound capacity by 0.395 Bcf/d (leaving 930 MMcf/d available) from June 25 through July 3. Intraday on June 24, no incremental volumes will be scheduled at St. John Eastbound. ANR warns of potential Firm Primary, Firm Secondary, and Interruptible curtailments, noting up to 34% impact against contracted MDQ though current nominations show 0% firm impact.
ANR force majeure removes 0.395 Bcf/d of Michigan Leg South eastbound capacity through July 3; expect bullish pressure on Chicago Citygate and Midwest basis with potential firm curtailments if nominations increase toward contracted MDQ levels.
Reroute: Moderate: TETCO (monitored), Trunkline/TGC (monitored), and PEPL (monitored) serve overlapping Gulf Coast-to-Midwest corridors, though ANR is a high-capacity pipe and partial reroute may not fully offset the 0.395 Bcf/d loss on this specific Michigan Leg segment.
