Iroquois Gas Transmission

Operational Flow Order

SEV 4/5
Operational Alert Until Further Notice

Iroquois Gas Transmission has declared an Operational Flow Order (OFO) effective January 15 gas day, in effect until further notice, for all points south of MLV-12, citing expected high volumes and adverse weather. All point operators must adhere strictly to scheduled volumes to maintain pipeline pressure; no unscheduled OBA gas is available, and Flow Control will be activated if necessary. The OFO has no stated end date and directly restricts flexibility for power plants and distribution customers in the New York and southern New England service area.

Iroquois OFO south of MLV-12 with no restoration timeline restricts delivery flexibility into the NYC metro and southern New England market; Iroquois Zone 2 basis has been running at -0.140 vs Henry Hub as of 2026-08-27 but expect significant bullish pressure on Zone 2 and Algonquin Citygate as the OFO tightens operational flexibility during a high-demand weather event with zero unscheduled gas available.
Reroute: Limited to none: Algonquin Gas Transmission serves overlapping southern New England and Connecticut markets, but if Algonquin is simultaneously stressed during the same weather event, there is effectively no reroute for affected Iroquois delivery points south of MLV-12, including Long Island and NYC metro customers.

Iroquois Gas Transmission

Operational Flow Order

SEV 4/5
Operational Alert Until Further Notice

Iroquois Gas Transmission has declared an Operational Flow Order (OFO) effective February 23rd gas day, valid until further notice, for all points south of MLV-12. The OFO is driven by expected high volumes and forecasted weather conditions, requiring all point operators to adhere strictly to scheduled volumes to maintain pipeline pressures; OBA gas is suspended and Flow Control may be activated. No end date has been specified, introducing sustained supply risk for New York and New England markets downstream of the affected segment.

Iroquois OFO south of MLV-12 with no restoration timeline tightens deliveries into New York and New England; Iroquois Zone 2 basis was -0.140 vs Henry Hub on 2026-08-27 (five-day average -0.190), and this open-ended OFO with weather-driven demand pressure is bullish for Zone 2 and Algonquin Citygate -- expect basis to widen further as unscheduled flexibility is eliminated and power plant burn nominations are constrained.
Reroute: Limited to none: Algonquin Gas Transmission provides partial alternative supply into New England and New York markets, but Algonquin and Iroquois are the two dominant pipes serving these markets and Algonquin is frequently simultaneously constrained during high-demand weather events, leaving minimal reroute headroom for volumes south of MLV-12.
