Tennessee

Although it lifted a meter-specific Balancing Alert OFO, Tennessee cited high temperatures across much of its system in saying a systemwide Imbalance Warning would become effective Wednesday. The action requires “all delivery and receipt point operators to match physical flow to scheduled volumes regardless of cumulative imbalance.” Later the pipeline also said that due to anticipated hot weather, it was issuing an OFO Action Alert for market-area Zones 5 and 6 that would take effect Thursday.

Southern California Gas declared a high-linepack OFO for Friday, setting the tolerance for positive daily imbalances at 10%.

Citing a need to maintain linepack and protect system integrity, Tennessee issued Monday a Balancing Alert OFO for market-area Zones 5 and 6, saying shippers in those zones were required to maintain an actual daily flow rate not exceeding a tolerance of 2% of scheduled quantities or 500 Dth, whichever is greater, for underdeliveries into the system and overtakes from the system.

Southern California Gas did not extend a high-linepack OFO beyond Saturday.

Citing limited operational flexibility to manage imbalances over the long holiday weekend, Tennessee issued a systemwide Balancing Alert for Saturday that required all delivery point operators to keep actual daily takes from the system equal to or greater than scheduled quantities, and all receipt point operators to keep actual daily receipts into the system equal to or less than scheduled quantities. The requirement applied in each case regardless of the operator’s cumulative imbalance position.

Tennessee lifted Monday a systemwide Imbalance Warning that had been implemented two days earlier.

Tennessee lifted Friday an Imbalance Warning for Zones 5 and 6, but asked customers to stay in balance.

The Line 523F-100 line-lowering project is being extended by one week through March 18 due to severe weather resulting in delays, Tennessee said. The work, previously projected for completion by Friday (March 11), is causing suspension of physical flow at the Thomas Cenac 1 (CI) and Lapeyrouse Plant Dehydration meters.

Neither Southern California Gas (SoCalGas) nor Pacific Gas and Electric extended their high-linepack OFOs beyond Saturday.
