Algonquin Gas Transmission

Weymouth Compressor Station Unplanned Outage

SEV 4/5
Compressor Issue capped at 0.020 Bcf/d, cut unknown 6 Days

Algonquin Gas Transmission experienced an unplanned outage at its Weymouth, MA compressor station on Gas Day October 16, 2026. South-to-North nominations through Weymouth will be reduced to 20,000 Dth/d (0.020 Bcf/d) on October 17, then cut to zero beginning October 18 through the duration of the outage, with an expected return to service for Gas Day October 23. The National Grid-Weymouth delivery point (loc_id 00827) showed zero scheduled throughput in the pre-event baseline (median 0.00 Bcf/d), suggesting the primary physical constraint falls on mainline south-to-north flow compression rather than the metered delivery tap itself.

Weymouth CS zero-flow restriction from Oct 18 blocks south-to-north Algonquin mainline compression for up to 6 gas days, tightening New England supply access and expect bullish pressure at Algonquin Citygate; the pre-event National Grid-Weymouth delivery meter showed 0.00 Bcf/d scheduled (loc_id 00827), so the volume impact is unquantified from posted meter data alone but the mainline compression loss is real and directionally bullish for New England basis.
Reroute: Limited to none: Algonquin and Iroquois are the two primary pipelines serving New England; Weymouth is a key mainline compression point on Algonquin's south-to-north mainline, and no bypass compressor path exists to fully replace its function for northbound flow into Boston-area markets.

Algonquin Gas Transmission

AGT Force Majeure

SEV 4/5
Force Majeure 7 Days

Algonquin Gas Transmission declared a force majeure on October 16, 2026 due to an unplanned outage at its Weymouth compressor station in the Boston/New England delivery region. The compressor station is expected to be returned to service by Gas Day October 23, 2026, a duration of approximately 7 days. No specific capacity volume is stated in the notice; pre-event flow data for the Weymouth area is not directly available in the POINT HISTORY block, so a grounded net reduction cannot be calculated.

AGT Weymouth force majeure tightens New England supply through October 23; expect bullish pressure at Algonquin Citygate as a key Boston-area compressor is offline with no reroute alternative -- Iroquois is the only partial mitigation but does not serve the same downstream points.
Reroute: Limited to none: Algonquin is one of two primary pipelines serving New England, and Weymouth compressor serves the Boston delivery area specifically; Iroquois Gas Transmission provides partial alternative for some southern New England and New York metro points but cannot replace Weymouth-dependent volumes into the Boston market.

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.

Algonquin Gas Transmission

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.
