Lake Arthur Compressor Station Maintenance (4246), Effective October 6 – 9, 2026

SEV 4/5Maintenance0.100 Bcf/d4 days
Summary
CGT has notified customers of planned maintenance at Lake Arthur Compressor Station from October 6-9, 2026, which will reduce backhaul delivery capacity at location 4246 (Cameron LNG) from 800,000 Dth/d (design) to 700,000 Dth/d -- a restriction of 100,000 Dth/d (0.100 Bcf/d). CGT explicitly warns that curtailments to Interruptible, Secondary Firm, and Primary Firm services are anticipated, and RCC provisions have been triggered. The four-day event directly reduces feed gas deliveries to Cameron LNG, an active LNG export terminal.
Trading note
CGT maintenance at Lake Arthur restricts Cameron LNG feed gas deliveries by 0.100 Bcf/d (from 0.800 to 0.700 Bcf/d) across Oct 6-9; live capacity data confirms Cameron LNG (loc 4246, BD:DPQ:FTS-1) currently scheduled at 0.669 Bcf/d against 0.800 Bcf/d operating capacity, consistent with the constraint -- reduced LNG export pull is bearish Henry Hub and Columbia Gulf mainline basis, which has most recently traded at -0.475 vs HH (2026-09-25).
Reroute potential
Limited: Cameron LNG feed gas supply is delivered via CGT's backhaul path and there are no immediate pipeline alternatives that can directly substitute for the curtailed CGT delivery into this terminal; partial offsetting supply may be available from other feed gas pipelines interconnecting Cameron LNG, but the firm service curtailment risk limits full reroute.
