03/18/2026- AGT Hourly Customer Specific Operational Flow Order
SEV 4/5
Operational Alert
Until Further Notice
Algonquin Gas Transmission has issued a Customer Specific Hourly Operational Flow Order effective March 18, 2026 and running until further notice (notice end date listed as June 16, 2026). The OFO restricts customer-specific hourly nominations system-wide with a No DP threshold of 25% / 250 MMBtu and a daily No DP threshold of 5% / 500 MMBtu. No restoration timeline is provided, indicating an open-ended system stress event on one of New England's two primary supply pipelines.
Algonquin Customer Specific Hourly OFO active system-wide until further notice -- expect significant widening at Algonquin Citygate versus Henry Hub, with spillover tightness at Iroquois Zone 2 and Tennessee Zone 6 if cold weather demand persists through the notice window.
Reroute: Limited to None: Algonquin and Iroquois are the two primary pipelines serving New England; if Iroquois is simultaneously stressed, there is zero reroute for core New England deliveries. Algonquin is the dominant supply path for CT, RI, MA, NH, and ME, and no alternate pipeline can replace constrained volumes at those delivery points.
