Operational Flow Order

SEV 4/5Operational AlertUntil further notice
Summary
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.
Trading note
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 potential
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.
