AGT Customer Specific Operational Flow Order -- EFF 4/18
In order to maintain the operational integrity of the system, Algonquin Gas Transmission, LLC (AGT) is issuing an Operational Flow Order (OFO) pursuant to Section 26 of the General Terms and Conditions of AGT's FERC Gas Tariff, effective 9:00 AM CCT April 18, 2026, for certain delivery point parties on the AGT system. AGT has contacted the affected parties.
This OFO does not affect the ability of AGT to receive or deliver quantities of gas for scheduled nominations to any customer or pipeline.
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 to avoid an OFO penalty except for primary firm no-notice nominations or shippers who can secure day ending Due Shipper supply for Due Pipe imbalances and Due Pipe supply for Due Shipper imbalances.
The individual OFO(s) will remain in effect until 9:00 AM CCT April 20, 2026.
