Delivery points included within each OFO group by segment can be found under “Other Postings” on the Southern Natural home page.


A daily entitlement report will be provided after the end of each scheduling cycle. The daily entitlement in effect after the last scheduling cycle (Intraday 3) will be the final one and will be used to determine any penalties. Maintaining deliveries within your daily entitlement at each delivery point will contribute to safe and efficient operation of the system, and also will avoid an OFO Type 3 penalty and help to minimize imbalances.


If you have questions, please contact your Account Manager or Scheduling Representative.
