Sonat implemented a systemwide OFO Type 6 for short imbalances effective Saturday until further notice. Tiered penalties of $1-15/Dth were applicable for negative daily imbalances exceeding a tolerance of 2% or 200 dekatherms, whichever was greater. Positive imbalances were unaffected. It was “highly likely” that the OFO would continue through Sunday, the pipeline said, but “too close to call” for Monday.

“The groundhog has done his thing and spring is just around the corner!” said Pacific Gas & Electric in announcing to customers Thursday that the Abnormal Peak Day (APD) window has closed for this winter. An APD occurs when the system composite temperature falls below a threshold of 27.4 degrees Fahrenheit, PG&E explained, and the probability of one prior to next winter is now nearly zero. Also, chances that Cold Winter Day conditions (a system composite temperature of 38 degrees F. or less) will strike this winter are greatly reduced, the utility added. “Accordingly, local curtailments or diversions driven by cold weather are far less likely — although still possible.”

Repairs related to a force majeure incident on its East Leg east of the Earlville (IA) Compressor Station (see Daily GPI, Feb. 6) have been completed and the segment is now back in service, Northern Natural Gas reported Friday morning. The pipeline extended a System Overrun Limitation notice for all market-area zones through at least Saturday.

ANR postponed engine maintenance at its Janesville (WI) Compressor that had been scheduled for Monday through Wednesday of this week.
