Carolina Gas Transmission (CGT) monitors system conditions and supply nominations for each cycle. If CGT determines that adverse changes have occurred in system conditions or one of the scheduling cycles, CGT may need to issue an OFO requiring shippers to take corrective actions. CGT can implement an OFO on 12 hours notice or less depending on the situation.

Shippers are encouraged to have personnel available, particularly over the weekend, in the event that it becomes necessary to implement an OFO.

Probability Codes:

Unlikely (UL) - an OFO is unlikely for this Gas Day
Too Close to Call (TCTC) - an OFO could be issued based on projected imbalance condition of the system. All Shippers should review their demand forecast and adjust supply, if needed, to remedy any projected imbalances.
Highly Likely (HL) - an OFO will be issued if the projected imbalance condition of the system does not moderate. All Shippers should take immediate effective action to remedy any imbalances.
OFO - an OFO is in effect. All Shippers should adhere to the OFO notice posted on CGT's Internet Website.

Positive imbalances - receipts are more than deliveries
Negative imbalances - receipts are less than deliveries

If you have any questions, please call your Interstate Marketing Manager.
