CAPACITY REDUCTION: GTN – Flow Past Kingsgate (Posted: 8/24/26)

SEV 4/5Maintenance2.550 Bcf/d10 days

Summary

Gas Transmission Northwest (GTN) has declared an unplanned maintenance outage at Unit 5D affecting Flow Past Kingsgate (LOC #3500), effective 8/26 through 9/4/2026. Available capacity is reduced to 2,550 MMcf/d (2.550 Bcf/d) for the duration. GTN explicitly warns that Firm Primary, Firm Secondary, and Interruptible curtailments are anticipated, and the Reservation Charge Crediting Mechanism has been activated.

Trading note

GTN unplanned outage at Kingsgate restricts 2.550 Bcf/d of Western Canada/PNW corridor capacity through 9/4; with Firm Primary curtailments possible and GTN Kingsgate basis already deeply negative (most recently -1.710 vs HH as of 2026-08-21), expect the constraint to tighten PG&E Malin and downstream California basis materially over the 8/26-9/4 window.

Reroute potential

Limited: GTN is the primary Western Canada-to-Pacific Northwest corridor feeding California via Malin; Ruby Pipeline (monitored) and Northwest Pipeline (monitored) provide partial Rockies-origin alternatives but cannot replace WCSB volumes at equivalent scale, and simultaneous system stress on any of these pipes would further limit relief.
