UPDATE - Station 160 Job 1211814 Planned Outage Maintenance Summary
Transco has updated the planned maintenance schedule at Station 160 (Mainline MP 1369.45) for Job 1211814, removing the May 28 cleaner tool run from the work scope. Pig run activities remain scheduled for May 21, June 2, June 4, and June 9, 2026. On those activity dates, design capacity of 2.221 Bcf/d is reduced to 1.947 Bcf/d available for primary firm service, representing approximately 0.274 Bcf/d of constrained capacity and an estimated 5-10% cut to primary firm shippers.
Transco mainline constraint at MP 1369.45 removes approximately 0.274 Bcf/d of primary firm capacity on discrete pig run dates through June 9, expect modest bullish pressure on Transco Zone 4 Southeast basis and downstream markets on affected days.
Reroute: Limited: Southern Natural Gas (SNG/EGT) provides a partial alternative for Southeast markets but carries significantly less capacity than Transco; Tennessee Gas Pipeline serves overlapping Northeast markets but cannot fully offset Transco mainline constraints at this volume level.
