03/18/2026- AGT Hourly Customer Specific Operational Flow Order

SEV 4/5
Operational Alert Until Further Notice

Algonquin Gas Transmission has issued a system-wide Hourly Customer Specific Operational Flow Order (OFO) effective March 18, 2026, and continuing until further notice (notice end date listed as June 16, 2026). The OFO imposes a No Deficiency Point constraint of 25%/250 on an hourly basis for all customers system-wide, indicating active system stress requiring shippers to maintain balanced or surplus positions on an intra-day basis. No specific capacity volume is stated, but the 'until further notice' language and system-wide scope signal an unresolved operational constraint.

Algonquin system-wide Hourly OFO active from March 18 with no firm restoration date -- expect significant bullish pressure at Algonquin Citygate and broader New England basis as shippers scramble to comply with hourly balancing requirements, with heightened spike risk given no reroute alternative exists for core New England deliveries.
Reroute: Limited to none: Algonquin and Iroquois are the two primary pipelines serving New England; Iroquois is not reported constrained at this time but cannot absorb full Algonquin system shortfall. No meaningful reroute exists for the core New England LDC market.

Systemwide Notes:
(1) AGT has scheduled Transco Centerville receipts to the design meter capacity of 222,526 Dth/d.
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.
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. 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, meter 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.
Customers are advised that capacity may become available as the nomination and confirmation process continues throughout the day.
Please contact your Operations Account Representative should you have any questions.
