Transwestern said a force majeure event at Compressor Station 2 near Flagstaff, AZ, caused the station to be taken out of service for repairs during the weekend. The outage is reducing Thoreau/West system capacity from to about 1,075,000 MMBtu/d through Tuesday, the pipeline said. It expects to restore Thoreau/West to its original capacity of 1,220,000 MMBtu/d Wednesday.

Southern California Gas declared a high-linepack OFO for last Friday and Saturday, then ended it Sunday.

Effective last Friday Northwest began cutting alternate gas northbound through the Kemmerer (WY) Compressor Station to the extent that Northwest can physically move balancing gas to replenish its Jackson Prairie storage balance. Customer nomination requests from Questar‘s Clay Basin storage facility have dropped to 50,000 Dth/d, Northwest said, leaving space for it to withdraw approximately 30,000 Dth/d from Clay Basin to move north to Jackson Prairie. In addition, Northwest is trying to arrange for receipt point operators located south of Kemmerer to pay back gas that Northwest can also move to Jackson Prairie. The pipeline said it would like to move approximately 0.5 Bcf into Jackson Prairie. “Currently, Northwest has been scheduling 690,000 Dth/d through Kemmerer, of which approximately 65,000 Dth is alternate gas,” a bulletin board posting said. “To the extent Northwest cannot move balancing gas to Jackson Prairie on a given day, Northwest will schedule customers’ alternate capacity requests. Northwest is taking this action at this time in an attempt to avoid having to request primary firm shippers to leave space through Kemmerer during the summer months as Northwest had to do last year. Adequate balancing gas in Jackson Prairie reduces the impact to customers during summer maintenance, and during the winter heating season and it is critical to 1) provide reliable firm service on a peak day, 2) provide balancing flexibility to reduce the likelihood, levels and duration of potential entitlements, and 3) mitigate OFOs through Kemmerer.”

Columbia Gas increased capacity through the Delhi Constraint Point in northeast Louisiana to 1,650,000 Dth/d Monday.
