Atlantic Bridge

The Atlantic Bridge Project will transport significant and diverse natural gas supplies to the New England states and the Canadian Maritime provinces.

The project is expected to provide reliability of energy throughout the region, and help 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.

Our goal is to place all the Atlantic Bridge facilities into service as soon as possible to meet the needs of the region. The first phase of Atlantic Bridge, providing 40,000 dekatherms per day of incremental firm transportation service, began operating in November 2017.

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. We anticipate placing Atlantic Bridge fully into service in the second half of 2020, following completion of the Weymouth Compressor Station, which will facilitate delivery of much-needed natural gas to project customers in Maine and Atlantic Canada.

Weymouth Compressor Station Construction Updates

Having received all necessary approvals, Algonquin Gas Transmission began construction activities for the Weymouth Compressor Station on Dec. 4, 2019.

Algonquin is committed to ensuring the site meets applicable environmental regulations, and to ensuring any work at the site is conducted safely, 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 construction 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.

Our goal is to place all the Atlantic Bridge facilities into service as soon as possible to meet the needs of the region. 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.

As the project proceeds, we will continue our commitment to responsible development, reliable operations and respectful, ongoing engagement with the communities we serve.
