Pacific Gas & Electric issued a systemwide Stage 2 high-inventory OFO for Saturday. It carried penalties of $1/Dth for exceeding a 10% tolerance on positive daily imbalances.

Late Thursday afternoon CIG declared a Strained Operating Condition (SOC) that took effect Friday until further notice. Ongoing primary FT requirements had resulted in “extremely high load factor operations” for its system, CIG said, and storage inventories were at or near its reservoir guidelines. “Therefore, CIG’s ability to absorb imbalances caused by mismatches between scheduled receipts and deliveries or those imbalances arising from variations in actual gas flow from scheduled quantities is extremely limited,” the pipeline continued. During the SOC shippers must keep receipts and deliveries in balance, it said, and storage customers should adjust flowing supplies to ensure that injections remain at or below current Available Daily Injection Quantity (ADIQ) limits. Injection rates in excess of ADIQ and/or inventory levels in excess of Maximum Available Capacity will be subject to unauthorized overrun charges. Capacity for interruptible injections will not be available. See the bulletin board for further details.

Noting that its storage capacity is fully subscribed under firm services, TGT notified Interruptible Storage Service (ISS) customers Friday that they have through Oct. 31 to remove all of their ISS volumes. TGT said it was providing more than the tariff-mandated minimum 30 days’ notice “to allow ISS customers as much time as practicable to manage their storage withdrawals.” They will be subject to an OFO penalty for all quantities remaining in ISS accounts at the end of the Oct. 31 gas day, TGT said.

Citing the current inventory level and projected injection rates at its Clay Basin storage facility, Questar said Friday it would stop accepting ISS injection nominations Saturday (Sept. 8). In addition, customers were required to begin withdrawal of all ISS working gas Saturday and complete the process within 30 days. Customers are permitted to transfer ISS volumes to any FSS accounts they may have.

Northwest completed anomaly repairs south of the Muddy Creek Compressor Station in time to restore the Muddy Creek South Constraint Point to design capacity Friday. A repair-related restriction had been expected to continue through Sept. 10 (see Daily GPI, Aug. 24). Northwest has scheduled mainline pipe replacements between the Pleasant View and La Plata B compressor stations for Tuesday through Thursday this week. At the same time it will be installing a new meter station and control valves at La Plata/Ignacio meter stations. Available capacity at Pleasant View and La Plata B will be reduced to zero during the work. If primary nominations do not net to zero, Northwest said, it will declare a deficiency period and allocate nominations accordingly.

Southern California Gas ended maintenance on a glycol heater at its Goleta storage field, which began Aug. 27 and caused a 340 MMcf/d loss of withdrawal capacity, as expected Friday (see Daily GPI, Aug. 31).

Northern Natural Gas declared force majeure late Friday afternoon at the Kansas Gas/NNG Rice County point due to a leak in the valve casing. Point capacity is zero from Friday through this coming Wednesday, when Northern expects to complete repairs.
