Algonquin’s Reliable Affordable Resilient Enhancement

The Northeast has endured some of the highest energy prices in the nation; the combination of high demand, colder-than-normal temperatures and system constraints have resulted in considerable economic strain on households and businesses throughout the region.

Algonquin Gas Transmission, LLC has proposed a new enhancement that will help provide stability in the marketplace. Algonquin’s Reliable Affordable Resilient Enhancement (AGT Enhancement) is the first step in alleviating the bottleneck of pipeline constraints that have plagued the region, helping to enhance peak-day capacity.

This is a targeted enhancement of existing pipeline infrastructure which is designed to upgrade the existing system within, or adjacent to, existing rights-of-way. AGT Enhancement will center around already existing infrastructure and will not require construction at any existing compressor stations or construct any new compressor stations.

Within Massachusetts, pipeline enhancements will occur in the towns of Mendon, Bellingham, Franklin and Wrentham. Upgrades in Rhode Island will take place in Cumberland, Little Compton, Tiverton and Burrillville.

Algonquin is proposing the following as part of the project:

• Replacing approximately 8.25 miles of existing 16-inch diameter natural gas transmission pipeline known as the G-1 pipeline through Worcester and Norfolk Counties, Massachusetts and Providence County, Rhode Island.
• Extending our 12-inch diameter G-2L pipeline approximately 2.2 miles in Newport County, Rhode Island.
• Installing approximately 3 miles of 36-inch diameter pipeline in Providence County, Rhode Island tying into our Burrillville discharge.
• Completing software modifications at our existing compressor station in Cromwell, Connecticut.

Subject to receipt of all necessary regulatory approvals, this work is expected to take place in 2028, with an in-service date expected in late 2028.

As part of the commitment to being good neighbors, Algonquin is engaging with community members, advocacy groups and local officials to understand any questions and incorporate feedback into project planning and execution.
