Force Majeure capped at 2.800 Bcf/d, cut unknown 29 Days

GTN has extended its Force Majeure at Flow Past Kingsgate (LOC #3500) from the previously stated end date of November 7 through November 27, 2026 -- a 20-day extension -- due to the ongoing equipment failure at Wallula Compressor Station Unit A. Available capacity remains capped at 2,800 MMcf/d (2.800 Bcf/d) throughout the extended window, with Firm Primary, Firm Secondary, and Interruptible curtailments all at risk. No pre-event baseline has been provided, so the net reduction relative to normal throughput remains unquantified.

GTN FM extension adds 20 days of Firm Primary curtailment risk at Kingsgate through 11/27 at the 2.800 Bcf/d cap; bullish for Sumas, Stanfield, and PG&E Malin basis as Western Canada import pipeline capacity stays restricted well into late November.
Reroute: Limited: GTN is the primary corridor for Western Canadian gas into the Pacific Northwest and California via Malin; Northwest Pipeline (NWP) provides partial Pacific Northwest coverage but cannot replace Canadian supply volumes constrained at Kingsgate.
