Algonquin Gas Transmission

08/07/2026- AGT Operational Flow Order -- EFF 8/8

SEV 4/5
Operational Alert Until Further Notice

Algonquin Gas Transmission has declared a system-wide Operational Flow Order effective August 8, 2026, and lasting until further notice (notice end date listed as 11/05/2026). The OFO prohibits daily pathing exceeding 4% over scheduled quantities (500 MMBtu minimum) for all system customers, with a tighter 2% / 500 MMBtu restriction applied to customer-specific nominations. No restoration timeline is given beyond 'until further notice,' indicating an open-ended supply management event on one of New England's two dominant interstate pipelines.

Algonquin system-wide OFO effective 8/8 with no fixed end date signals tightening New England supply balance; expect bullish pressure at Algonquin Citygate and elevated New England basis vs Henry Hub, with risk of extreme spike if Iroquois faces simultaneous constraint.
Reroute: Limited to none: Algonquin and Iroquois are the two primary pipelines serving New England; if Iroquois is simultaneously constrained, there is zero reroute available and extreme basis spikes are likely at Algonquin Citygate.

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.
