Yankee Gas - AGT OFO Lifted Effective Gas Day 3/16/2026 ONLY _______________________________________________________________________________________________________________ For your information only, Pipeline communications are copied in below: Eversource Gas Supply EEGasTrading&Scheduling@eversource.com From: InfoPost@enbridge.com <InfoPost@enbridge.com> Sent: Monday, March 16, 2026 8:17 AM To: LinkSystem@spectraenergy.com Subject: Critical,OFO,20260316,AGT,006951446
Effective 9:00AM CCT, March 16, 2026, Algonquin Gas Transmission (AGT) is lifting the previously posted system wide Operational Flow Order (OFO). However, in order to maintain the operational integrity of the system, AGT is issuing an OFO pursuant to Section 26 of the General Terms and Conditions of AGT's FERC Gas Tariff effective 9:00 AM CCT, March 17, 2026, to all parties, with the exception of those Operational Balancing Agreements required by FERC regulations, on the AGT system. 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. The penalty shall apply to each dekatherm of actual delivery quantities that exceeds the greater of 500 DTH or 105% of scheduled delivery quantities. The penalty will be equal to three times the 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.
As previously posted AGT, requests that customers/point operators on AGT be aware of the impact non-ratable hourly takes from the system may have in causing delivery pressures reaching lower than desired levels. As a reminder, AGT's system is not designed to sustain delivery pressures above contract levels while making non-ratable/accelerated deliveries above scheduled quantities for more than 6 consecutive hours, to be followed by flows below scheduled quantity for the balance of any 24-hour period. Furthermore, if customers/point operators don't manage hourly takes from the system, 1) delivery pressures will be impacted and /or 2) AGT may be required to impose further restrictions or courses of action in order to maintain the operational integrity of the system. 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.
AGT requires any imbalance payback (Due Pipe or Due Shipper) to be coordinated through your Operations Account Representative. If necessary, AGT will utilize any provision of its tariff to ensure system integrity including the issuance of customer specific or system wide OFOs. This OFO will remain in effect until further notice. Please contact your Operations Account Representative should you have any questions. Please refer to the table below for the effected AGT operational areas, dates, and tolerance percentages:
