Citing lower linepack and its limited operational flexibility to manage market-area imbalances, Tennessee declared an Imbalance Warning in downstream Zones 5 and 6 Thursday. It requires all delivery point operators to keep actual daily takes out of the system equal to or less than scheduled quantities, and all receipt point operators to keep actual daily receipts into the system equal to or greater than scheduled quantities. Both conditions apply regardless of cumulative imbalance positions.

Multi-dollar leaps reigned again in the Northeast, while the rest of the market saw gains ranging from about a nickel to nearly 30 cents.
