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.
