New Projects - U.S.

Atlantic Bridge

The Atlantic Bridge Project, a proposed expansion of the Algonquin Gas Transmission (Algonquin) and Maritimes & Northeast Pipeline (Maritimes) systems, will connect the New England states and Maritime provinces with abundant, regional natural gas supplies.

The Atlantic Bridge Project will provide additional capacity on the Algonquin and Maritimes systems to move reliable, economical natural gas into New England and Atlantic Canada in time for the start of the 2017-2018 winter heating season. The additional supply from Atlantic Bridge will help enhance the reliability of energy throughout the region and generate savings for homeowners, businesses, and manufacturers.

Algonquin and Maritimes have signed separate long-term contracts for natural gas transportation service, beginning in November 2017, with seven shippers – four local distribution companies, two manufacturing and industrial companies, and a municipal utility located in Connecticut, Massachusetts, Maine and Atlantic Canada.

The Atlantic Bridge Project will not be designed for nor will the project be used to transport natural gas for export as liquefied natural gas (LNG). The additional supplies will be used exclusively within New England and the Canadian Maritime Provinces.

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 October 22, 2015, Algonquin and Maritimes filed with FERC a formal application for a Certificate of Public Convenience and Necessity that will allow 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.

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

Project Timeline

  • ŸPre-filed with FERC Jan. 2015
  • ŸFiled FERC application Oct. 2015
  • ŸReceive FERC certificate in second half of 2016
  • ŸIn-service in second half of 2017

FERC approved Algonquin’s and Maritimes’ request to participate in the “Pre-file” process, a series of activities which provide interested parties – including landowners, public officials, community members, government agencies and FERC staff – an opportunity to review project-related information and identify issues prior to us submitting to FERC a formal application.

The Atlantic Bridge Project was assigned a Pre-file docket number of PF15-12-000. Following the application filing, the Pre-file docket number (PF15-2-000) was converted to FERC Docket No. CP16-9-000.

FERC is conducting a comprehensive review of environmental impacts that could result from the construction and operation of the proposed facilities in accordance with NEPA. As part of its review, FERC issued a Notice of Intent to prepare an Environmental Assessment (pdf, 903 KB) and initiate a public scoping period.

During the scoping period, FERC encouraged the public and agencies to provide comments on potential environmental issues by June 11, 2015. FERC will continue to accept comments after the scoping period. Comments may be submitted verbally or in writing at the public Scoping Meetings; electronically on FERC's website using the eComment or the eFiling feature under the link to Documents and Filings; or by mail to this address:

In March, we held a series of open houses to provide information and gather input on the Atlantic Bridge Project. The project calendar lists the dates and locations of the open houses.

In early 2014, the Atlantic Bridge Project completed an open season (pdf, 4.4 MB) for customers to submit requests for additional natural gas service with a target in-service date of November 2017. We are moving forward with the Project based upon the market’s positive response to the open season.

Atlantic Bridge is designed to minimize disturbances to landowners, communities, and the environment. Proposed facilities include:

  • Construction of approximately 6.3 miles of 42-inch diameter mainline take-up and relay pipeline within Algonquin’s existing footprint in New York and Connecticut
  • Construction of a new compressor station with 7,700 horsepower in Weymouth, Massachusetts
  • Addition of two new compressor units, for a total of 14,000 additional horsepower, at two existing compressor stations in Connecticut
  • Replacement of two existing compressor units, for a total of 1,500 horsepower, at an existing compressor station in Connecticut
  • Use of reserve capacity in one compressor unit, for a total of 3,300 additional horsepower, at an existing compressor station in New York
  • Construction of a new meter station in Connecticut and modifications to existing meter stations in New York, Connecticut, Massachusetts and Maine
