Summary
Gas Transmission Northwest has updated the capacity restriction at Station 6 CFTP (Loc #954690) associated with the Starbuck Outage and Bypass Installation, reducing available capacity to 1,550 MMcf/d (1.550 Bcf/d), down from the previously posted 1,600 MMcf/d. The restriction is in effect from 08/18/2026 through 08/29/2026 and GTN has flagged it as Critical with anticipated Firm Primary, Firm Secondary, and Interruptible curtailments. This is a first-time initiation notice (Revision 1, not a stale revision), reflecting an update to the capacity figure that accompanies the original outage posting.
Trading note
GTN Station 6 CFTP constraint at 1.550 Bcf/d through 08/29 with firm curtailment exposure; GTN Kingsgate basis has averaged -1.585 vs Henry Hub over the five trading days ended 2026-08-17 (most recently -1.565 on 2026-08-17), and further tightening of this Western Canada/PNW import corridor should pressure Kingsgate and PG&E Malin basis higher as downstream California supply diminishes.
Reroute potential
Limited: GTN is the primary Western Canada-to-Pacific Northwest corridor; Northwest Pipeline (NWP) provides partial Pacific Northwest alternative but does not fully replicate Canadian supply volumes into California, and Ruby Pipeline serves a different Rockies-to-Malin path that may absorb some displaced demand at premium.
