Imbalance

After allowing a previous high-linepack OFO to expire Monday, Southern California Gas (SoCalGas) declared a new one for Wednesday, setting a positive daily imbalance tolerance of 10%. However, the e-mailed OFO notice did not get sent until shortly after 7:30 a.m. CDT Wednesday morning. Spokeswoman Denise King confirmed that despite the late announcement, Wednesday was the effective date of the OFO. SoCalGas also said Wednesday it had completed the final tie-in of field Line 159 at its Goleta storage facility; the work previously had been expected to last through Friday. The early finish allowed the utility to restore 140 MMcf/d of withdrawal capacity and 60 MMcf/d of injection capacity at Goleta.

Tennessee said it will implement Tuesday an Imbalance Warning requiring customers to match physical flow with scheduled quantities in Zones 0, 1, L, 2 and 4 upstream of Station 219 to prevent imbalances that would threaten its operational integrity. “Due to mild weather, Bear Creek storage field testing and high utilization through Station 219 Tennessee does not have the ability to absorb imbalances caused by overdeliveries by receipt point operators into the system and undertakes from the system by delivery point operators,” the pipeline said.

Tennessee said Monday it was lifting a systemwide imbalance warning but continued to request that all parties match physical flow with scheduled quantities.

Tennessee implemented an Imbalance Warning for market-area Zones 5 and 6 Thursday, saying effective immediately it requested that customers match physical flow with scheduled quantities to prevent imbalances in those zones that would threaten the pipeline’s operational integrity. “Due to the emergent repair issue at Station 321 and high demand in the Northeast, Tennessee does not have the ability to absorb imbalances caused by underdeliveries by receipt point operators into the system and overtakes from the system by delivery point operators.”

Tennessee issued a systemwide Imbalance Warning, saying effective Friday it requests that customers match physical flow with scheduled quantities to prevent imbalances that would threaten operational integrity. “Due to anticipated colder weather across much of the system, Tennessee does not have the ability to absorb imbalances caused by underdeliveries by receipt point operators into the system and overtakes from the system by delivery point operators.”
