Atlantic Bridge



The Atlantic Bridge Project enables the transportation of significant and diverse natural gas supplies to the New England states and the Canadian Maritime provinces.

The project provides reliability of energy throughout the region, and helps generate savings for homeowners, businesses, and manufacturers.

The Atlantic Bridge Project is designed to provide additional capacity on our Algonquin Gas Transmission and Maritimes & Northeast Pipeline systems to move reliable, economical natural gas into New England and to specific end use markets in the Canadian Maritime provinces.

In November 2017, the first phase of Atlantic Bridge began service, providing 40,000 dekatherms per day of incremental firm transportation service.

Project facilities in New York were placed into service in the fall of 2019, and allowed for the full project capacity to be available from New Jersey to Massachusetts. The Atlantic Bridge project was placed into full service in January 2021, following completion of the Weymouth Compressor Station, which facilitates delivery of much-needed natural gas to project customers in Maine and Atlantic Canada.

Project Information:

Weymouth Compressor Station

Algonquin Gas Transmission began construction activities for the Weymouth Compressor Station on Dec. 4, 2019, and placed the facility fully in service on January 25, 2021.

Algonquin is committed to ensuring the Weymouth Compressor Station continues to meet applicable environmental regulations, and to operating the facility safely and responsibly, with public health and safety as our priority. The Release Abatement Measure (RAM) Plan for the site of the Weymouth Compressor Station was carefully developed to ensure activities are conducted in compliance with all applicable environmental requirements.

The RAM Plan was finalized following public input and comments as part of a transparent process. Click here to view the site's RAM Plan.


FERC Applications and Certificates

The Federal Energy Regulatory Commission (FERC) is an independent federal agency that regulates the interstate transmission of natural gas and exclusively authorizes the construction of new interstate natural gas facilities. FERC is also the lead federal agency responsible for conducting environmental reviews of interstate natural gas projects in compliance with the National Environmental Policy Act (NEPA).

On January 25, 2017, FERC issued the Certificate of Public Convenience and Necessity for the Atlantic Bridge Project following a comprehensive review and evaluation by FERC that included substantial public and agency participation throughout the pre-filing process and formal application review process.

On October 22, 2015, Algonquin and Maritimes filed with FERC a formal application for a Certificate of Public Convenience and Necessity that allows the construction and operation of the Atlantic Bridge Project.

The Atlantic Bridge Project was assigned docket number CP16-9-000. You may visit FERC’s website and enter the docket number to follow the project.

On October 27, 2017, FERC granted Algonquin Gas Transmission’s request to place into service the Atlantic Bridge Connecticut facilities to provide 40,000 dekatherms per day of incremental firm transportation service. The project facilities in New York were placed into service in the fall of 2019, and allowed for the full project capacity to be available from New Jersey to Massachusetts. The Atlantic Bridge project was placed fully into service in January 2021.
