Saturday

Citing limited operational flexibility to manage imbalances, Tennessee said a systemwide Imbalance Warning will go into effect Saturday and require all delivery point operators “to keep actual daily takes out of the system equal to or greater than scheduled quantities regardless of their cumulative imbalance position. All receipt point operators are required to keep actual daily receipts into the system equal to or less than scheduled quantities regardless of their cumulative imbalance position.” If compliance is not sufficient, Tennessee said, it may take further actions, including contract- or meter-specific OFOs to maintain operational integrity.

Two days after ending a previous one, Pacific Gas and Electric issued a new systemwide Stage 2 high-inventory OFO for Saturday on its California Gas Transmission system with $1/Dth penalties for exceeding a daily positive imbalance of 5%.

Florida Gas Transmission ended Saturday an Overage Alert Day that had been in effect continuously since July 8.

Questar said the first phase of a pressure uprate in its ML 68 segment was progressing on schedule and was expected to be completed by the start of last Saturday’s gas day. “No special restrictions will be in place until the next phase of the work begins” Tuesday, the pipeline said.

CIG declared a force majeure following an engine turbocharger failure at its Laramie East Compressor Station. Effective with Saturday’s gas day CIG was reducing station capacity form 770 MMcf/d to 680 MMcf/d until further notice. Currently the capacity is fully subscribed at the 770 MMcf/d level, the pipeline said.

Pacific Gas and Electric kept a systemwide Stage 2 high-inventory OFO that it had initiated Saturday on its California Gas Transmission system in effect through Monday but ended it for Tuesday.

Florida Gas Transmission ended a lengthy period of Overage Alert Days Saturday.

Southern California Gas declared a high-linepack OFO for Saturday, with Buy-Back penalties applying to deliveries exceeding 10% of nominated quantities.

After ending a high-linepack OFO Friday, Southern California Gas issued another one for Saturday, retaining the same 10% tolerance for positive daily imbalances.
