Summary
Rockies Express is restricting Segment 250 capacity to 1.085 Bcf/d westbound-to-eastbound (West to East direction) effective timely cycle Gas Day September 3, 2026, until further notice, due to an ongoing operational issue at Bertrand Compressor Station (Update #17). At this restriction level, primary firm, secondary firm, and ITS/AOR service classes are all explicitly at risk of curtailment. No restoration timeline has been provided.
Trading note
REX Segment 250 restricted to 1.085 Bcf/d eastbound with primary firm at risk -- a multi-week unresolved constraint with no end date; REX Zone 3 delivered basis has averaged -0.313 vs HH over the five trading days ended 2026-09-01 (most recently -0.285 on 2026-09-01) and should widen further bearish as eastbound throughput remains capped, while Rockies/Cheyenne Hub faces bearish pressure from trapped westbound supply; Trailblazer shares Bertrand CS and is not an independent reroute.
Reroute potential
None: Trailblazer Pipeline (TPC) shares Bertrand Compressor Station with REX and is simultaneously constrained by the same facility -- the two are not independent reroutes for each other. The REX/TPC SALINE and TPC/REX LONE TREE WELD REC interconnects are both shown at 100% utilization (0.642 Bcf/d and 0.579 Bcf/d respectively, zero headroom) in current capacity data, corroborating the constraint.
