Enbridge Proposes Algonquin Pipeline Enhancements to Ease Northeast Constraints

Algonquin Gas Transmission has proposed targeted upgrades to its existing pipeline system in Massachusetts and Rhode Island, aiming to ease Northeast capacity constraints and improve peak-day gas reliability without adding new compressor stations.

(P&GJ) — Algonquin Gas Transmission, LLC has proposed a targeted enhancement to its existing pipeline system aimed at easing capacity constraints and improving peak-day reliability across the Northeast, a region that continues to face some of the highest energy prices in the U.S.

The proposal, known as the Reliable Affordable Resilient Enhancement (AGT Enhancement), is designed to address longstanding system bottlenecks that have limited natural gas delivery during periods of high demand, particularly in colder-than-normal weather. Algonquin said the project would focus on incremental upgrades to existing infrastructure rather than major new construction.

According to the company, the enhancement would take place within or adjacent to existing rights-of-way and would not require construction at existing compressor stations or the addition of new compressor facilities. The approach is intended to improve peak-day capacity while minimizing construction impacts.

In Massachusetts, the proposed upgrades would occur in Mendon, Bellingham, Franklin and Wrentham. In Rhode Island, work is planned for Cumberland, Little Compton, Tiverton and Burrillville.

Subject to regulatory approvals, Algonquin expects construction to take place in 2029, with the project entering service later that year.

Algonquin said it is engaging with community members, advocacy groups and local officials as part of the planning process to address questions and incorporate feedback ahead of final design and execution.
