Algonquin joined upstream affiliate Texas Eastern in advising customers that due-shipper imbalance gas will not be available until further notice (see Daily GPI, Nov. 27). However, unlike Texas Eastern’s restriction on interruptible deliveries, Algonquin said Wednesday it “is not issuing any system restrictions at this time.”

Northwest asked shippers for a voluntary reduction in northbound nominations through the Kemmerer (WY) Compressor Station bottleneck over the four-day holiday weekend. “We have experienced drafting in the Pacific Northwest and nominations have been high through Kemmerer,” the pipeline said Tuesday afternoon. Kemmerer was scheduled at 535,000 dekatherms for that gas day compared to physical capacity of almost 500,000 Dth with mobile compression on, Northwest added. Though the forecast indicated some warming for the weekend, market-area temperatures are expected to remain cold, it said.

Sonat reported implementing Monday night a nomination enhancement allowing its SoNet Premier system to verify a shipper’s nomination “even if its contract is out of balance by less than 5 [dekatherms].” As of Tuesday a shipper could nominate out of balance by 4 dekatherms or less and the nomination would be verified and submitted successfully, eliminating the necessity to balance a contract due to minor rounding differences, Sonat said. It noted that the enhancement was “strictly for nomination purposes only and all contracts will be scheduled back into balance at the end of each nomination cycle based on the rankings provided…in the nomination.”
