Northern Natural Gas allowed a System Overrun Limitation for all zones to expire Saturday.

Tennessee will implement Imbalance Warnings in downstream market-area Zones 5 and 6 Saturday, saying it has limited operational flexibility to manage imbalances there over what is predicted to be a cold long holiday weekend. All delivery point operators in the zones will be required to keep actual daily takes out of the system equal to or less than scheduled quantities regardless of their cumulative imbalance position. Receipt point operators must keep actual daily receipts into the system equal to or greater than scheduled quantities regardless of their cumulative imbalance position.

Saying it needed to protect system integrity and due to excessive hourly takes exceeding scheduled quantities, Tennessee issued meter-specific Balancing Alert OFOs Monday affecting two LMSMA contracts (71054 and 943030). They are required to maintain an actual daily flow rate not exceeding 2% or 500 Dth, whichever is greater, of scheduled quantities.

Tennessee lifted Thursday an OFO Action Alert for all balancing parties in Zones 5 and 6.

Tennessee lifted Wednesday an Imbalance Warning in Zones 0, L, 1, 2, 3 and 4 but continued to request that all parties match physical flow with scheduled quantities.

Saying it had limited operational flexibility to manage imbalances in upstream Zones 0, L, 1, 2, 3 and 4 over the long holiday weekend, Tennessee issued an Imbalance Warning for shippers in those zones effective Friday until further notice.

Receipt point operators must keep actual daily receipts into the system equal to or less than scheduled quantities regardless of their cumulative imbalance position.

Tennessee lifted Wednesday a longstanding Imbalance Warning in upstream Zones 0-4 but said it continues to request that all parties match physical flow with scheduled quantities.

Citing forecasts of cold weather in market-area Zones 5 and 6 limiting its operational flexibility to manage imbalances, Tennessee said it implemented an Imbalance Warning in those zones at the start of Friday’s gas day. All affected delivery point operators were required to keep actual daily takes out of the system equal to or less than scheduled quantities regardless of their cumulative imbalance positions, while receipt point operators had to keep actual daily receipts into the system equal to or greater than scheduled quantities regardless of their cumulative imbalance positions.
