Flexibility

Citing limited operational flexibility, mild weather and testing at its Harrison storage field, Tennessee said a systemwide OFO Action Alert will become effective Thursday until further notice for all Balancing Parties. They are required to maintain an actual daily flow rate not exceeding 2% of scheduled quantities or 500 Dth, whichever is greater, for overdeliveries into the system and undertakes from it.

Saying it had limited operational flexibility to manage imbalances, Tennessee issued a systemwide Imbalance Warning effective Saturday that barred the creation of positive daily imbalances.

Citing limited operational flexibility and mild weather, Tennessee said a systemwide OFO Action Alert will take effect Saturday for all Balancing Parties. Penalties will apply to all such parties who exceed a positive daily imbalance tolerance of 2% of scheduled quantities or 500 Dth, whichever is greater. “In the event the OFO Action Alert is not sufficient to maintain the operational integrity of the system, Tennessee may issue a Critical Day or an OFO Balancing Alert,” the pipeline said.

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.

Affiliates Algonquin and Texas Eastern both reported “limited operational flexibility to manage imbalances” Thursday, and along with a request that shippers and point operators adhere to scheduled volumes, they said effective Friday no nominations for due-pipe imbalance makeups or that create due-shipper imbalances will be allowed. This restriction will remain in effect through Monday, the pipelines said.

Citing “limited operational flexibility, high storage levels and continuing mild weather,” Tennessee said a systemwide OFO Action Alert will become effective Saturday for all Balancing Parties, “including LMS-PA, SA contracts acting as balancing parties, LMS-MA and LMS-PL balancing parties.” Affected customers will be required to maintain an actual daily flow rate not exceeding 2% above scheduled quantities or 500 Dth, whichever is greater, for overdeliveries into the system and undertakes from the system. See the bulletin board for details.

Citing limited operational flexibility and continuing mild market-area weather, Tennessee said Friday an OFO Action Alert would become effective Sunday for all Balancing Parties (including LMS-PA, SA contracts acting as balancing parties, LMS-MA and LMS-PL balancing parties). The positive imbalance tolerance was set at 2% of scheduled quantities or 500 Dth, whichever is greater. In addition, Tennessee lifted Friday a force majeure declaration made Sept. 23, 2008 for three Grand Isle meters on its 524C 400, 500 and 700 lines offshore Louisiana. The force majeure remains in effect for three other meters on the 523A-100, 524C-400 and 524C-600 lines, the pipeline added. Tennessee also said Friday it had completed emergent repairs on two D Building compressor motors at Compressor Station 54 in Greenville, MS (see Daily GPI, April 13) and the station has resumed normal operations.
