Ridgeline Tie-In Maintenance (HartSEG & 4166), July 14-31, 2026

SEV 4/5

Maintenance 0.345 Bcf/d 18 Days

CGT has issued a Critical notice for planned Ridgeline Tie-In maintenance on Mainlines 200 and 300 from July 14-31, 2026. Backhaul capacity through HartSEG will be reduced from design capacity of 2.545 Bcf/d to approximately 2.200-2.400 Bcf/d (a loss of roughly 0.145-0.345 Bcf/d), with the midpoint loss near 0.245 Bcf/d. Additionally, the City of Gallatin (meter 4166) will be taken to zero capacity July 14-23. CGT explicitly warns that Interruptible, Secondary Firm, AND Primary Firm service curtailments are possible, triggering a high-severity assessment despite this being planned maintenance.

CGT planned maintenance removes up to 0.345 Bcf/d of backhaul capacity through HartSEG July 14-31, with explicit primary firm curtailment risk flagged -- expect bullish pressure on Transco Zone 4 Southeast basis and tightening at Henry Hub as Gulf Coast-to-Appalachian backhaul throughput is reduced.

Reroute: Moderate: Texas Eastern (TETCO) and Trunkline (TGC) serve overlapping Gulf Coast northbound corridors and may absorb some displaced volumes, but the explicit primary firm curtailment warning suggests CGT system utilization is high enough that partial reroute on competing pipes may not fully offset the constraint.

Notice Text:
Columbia Gulf Transmission, LLC (CGT) notifies customers that based on forecasted colder temperatures and increased market demand across the system, a change to the AutoPAL limits is necessary. Effective Evening Cycle for Gas Day Friday, January 23, 2026, and continuing until further notice, the following AutoPAL limits will be implemented:

AutoPAL Parks:  25,000 Dth (currently 5,000 Dth)

AutoPAL Loans:  3,000 Dth (currently 5,000 Dth) 

As a reminder, these limits will be applied to each pool (P20, P30) beginning with the Evening Cycle for each Gas Day. AutoPAL quantities in excess of the posted limits will be force-balanced based on each pool’s rankings. Therefore, customers are encouraged to update their pool rankings accordingly. 

Please continue to monitor the AutoPAL availability, which is located at the bottom of CGT’s Daily Capacity Posting, and contact your Customer Services Representative with any questions.

Notice Text:
The authentication issue affecting access to the TC eConnects application has now been resolved.

Earlier, TC Energy was aware of a service disruption with our authentication vendor, Okta, which prevented some users from logging in. This issue has since been addressed, and normal access to TC eConnects has been restored.

If you continue to experience login issues, please contact the EBB Security group at 832-320-5291 or 832-320-5150 for assistance.

Thank you for your patience.
