While extending a systemwide high-inventory OFO through at least Friday, Pacific Gas and Electric maintained the tolerance on positive daily imbalances at Thursday’s 12% but expanded the OFO status to Stage 3 and raised noncompliance penalties to $5/Dth.

Emulating week-earlier actions, affiliated pipelines Texas Eastern and Algonquin said Thursday they have limited operational flexibility to manage imbalances, and thus would not allow any nominations for due-pipe imbalance makeups or creation of due-shipper imbalances from Saturday until the start of Tuesday’s gas day.

Southern Natural Gas noted that a shut-in test of its Muldon storage facility in Mississippi is scheduled for Tuesday through around mid-afternoon Oct. 16, during which each CSS customer will be allocated to 36% of its currently effective Daily Injection Quantity and Daily Withdrawal Quantity. Southern added that “based on historically high storage inventory levels and projected high injection requirements for the upcoming weekend,” it expects to implement a Type 6 OFO for long imbalances starting Saturday. “Further, it is also highly likely that once the Type 6 OFO is implemented it will remain in effect through the shut-in test,” Southern said.
