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.

A week after rescinding an Imbalance Warning for market-area Zones 5 and 6 that had been aimed at avoiding low linepack due to cold weather-related overtakes at delivery points, Tennessee said it is implementing a systemwide Imbalance Warning Friday. But this time the pipeline cited moderating weather across much of its system in asking customers to match scheduled volumes and actual flows so linepack will not reach excessive levels.
