AGT Operational Flow Order -- EFF 5/19
This OFO does not affect the ability of AGT to receive or deliver quantities of gas for scheduled nominations to any customer or pipeline.
During the effectiveness of this OFO, all parties must be balanced such that actual deliveries of gas out of the system must be equal to or less than scheduled deliveries out of the system. The penalty shall apply to each dekatherm of actual delivery quantities that are greater than scheduled quantities plus 500 Dth or 110% of scheduled delivery quantities. The penalty will be equal to three times the arithmetic average of daily Platts Gas Daily "Daily Price Survey" posting for the High Common price for "Algonquin, city-gates" for the day on which such violation occurred as indicated in AGT's General Terms and Conditions Section 26.8. In addition, AGT will not permit retroactive nominations from upstream interconnects governed by a FERC gas tariff to avoid an OFO penalty.
AGT may be required to issue system specific and/or hourly OFO's pursuant to General Terms and Conditions Section 26.7(d) to impose further restrictions in order to maintain the operational integrity of the system.
This OFO will remain in effect until 9:00 AM CCT, May 20, 2026.
