OFO ALERT: Yankee Gas Critical Day declared aggravated by over-delivery effective gas day 10/11/2025 through 10/13/2025 on AGT - DO NOT LEAVE

Note:

· DO NOT LEAVE more than 5% and, DO NOT TAKE more than 10%
· Any related penalties due to noncompliance will be calculated in accordance with penalty provisions of Rate TRS and Rider BAL
· Yankee Gas has the right to reject intra-day nominations and implement additional tolerance tightening at any time.
· Per our tariff, Yankee Gas will not accept retroactive nominations on any day in which Yankee Gas has an OFO in effect.

In order to maintain the operational integrity of the system, 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, October 11, 2025, 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 greater than scheduled deliveries out of the system. The penalty shall apply to each dekatherm of actual delivery quantities that are less than scheduled quantities minus 500 Dth or 95% 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, October 14, 2025.
