OFO ALERT: Yankee Gas Critical Day declared aggravated by under-delivery effective gas day 1/2/2025 until further notice on AGT - DO NOT TAKE

Note:

· DO NOT TAKE more than 2% and, DO NOT LEAVE 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, January 2, 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 less than scheduled deliveries. The penalty shall apply to each dekatherm of actual delivery quantities that exceeds the greater of 2,000 Dth or 102% 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.

This OFO will remain in effect until further notice.

Please contact your Operations Account Representative should you have any questions.
