East Tennessee Natural Gas

08/04/2026- Wartburg to Topside 3100-1 Unplanned Outage

SEV 3/5
Capacity Constraint 91 Days

East Tennessee Natural Gas has declared an unplanned outage on its 3100-1 Line Valve Section 1 between Wartburg Compressor Station and Topside, caused by third-party activity. Effective immediately, ETNG is lowering line pressure on the affected segment until remediation is complete, with one meter (MR 59337 - Ariana Energy Morgan Co. 9) taken out of service. ETNG states it does not anticipate nomination reductions through Wartburg at this time, but the notice end date extends through November 2, 2026, suggesting an extended remediation window.

Unplanned third-party damage on ETNG 3100-1 reduces operating pressure on the Wartburg-Topside segment through early November 2026; no stated volume loss but pressure reduction affecting downstream meters warrants monitoring for escalation to nomination curtailments, with bullish implications for local Southeast Appalachian basis if nominations are later impacted.
Reroute: Moderate: Transco and Columbia Gas Transmission (TCO) serve overlapping Southeast and Appalachian markets, though East Tennessee serves specific local distribution points in Tennessee with limited bypass for directly affected meters on this segment.
