Subject:  Type 6 OFO Long Eff. 03-29-24
Notice Text:

Based on the current milder weather forecast and associated demand on Southern's system, effective for the start of the gas day, Friday, March 29, 2024, and until further notice, Southern is implementing a Type 6 OFO for long imbalances. In order to maintain the operational integrity of Southern's system, it is essential that Shippers and Poolers remain in balance (including their available no-notice injection entitlements).

The OFO Type 6 order will subject each Shipper/Pooler to the following tiered imbalance penalties:

Daily Imbalance Penalty

Percent of Allocated Deliveries

Per Dth

0 - 2% or < 200 dth

No Penalty

> 2 - 5%


> 5 - 8%


> 8%


Since the projected operational conditions are affected by receipts exceeding deliveries, the penalty will apply only to each Shipper/Pooler that has a net long imbalance (i.e., the party's total allocated receipts exceed total allocated deliveries including available no-notice storage injections). Southern cannot accept unscheduled imbalances and requires all customers to nominate and schedule all payback requests.


If you have any questions regarding the OFO, please call your Account Manager or Scheduling Representative.
