New Projects and Our Process


Algonquin Incremental Market (AIM) Project

Project Status: Regulatory Review

Map: Proposed Algonquin Incremental Market Expansion

  • Location: New York, Connecticut, Rhode Island and Massachusetts
  • Proposed Facilities: See detail below
  • Capacity: Up to 342,000 dekatherms per day
  • Ownership: 100 percent Spectra Energy Partners
  • Full Project Completion Date: November 2016
  • FERC Docket Number: CP14-96-000


The Algonquin Incremental Market (AIM) Project will provide the Northeast with a unique opportunity to secure a cost effective, domestically produced source of energy to support its current demand, as well as its future growth, for clean burning natural gas.

The AIM Project — an infrastructure investment that expands the pipeline capacity of our existing Algonquin Gas Transmission system — will allow abundant regional natural gas supplies from the Appalachian basin to flow reliably into the Northeast, helping to meet the increasing demand while lowering energy costs.


Recognizing the critical need for additional pipeline capacity to move these new natural gas supplies into the region, public officials and organizations from across the Northeast have expressed support for the AIM Project.



The Federal Energy Regulatory Commission (FERC) 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.

On February 28, 2014, Algonquin filed with FERC an application for authorization to construct and operate the AIM Project and was assigned docket number CP14-96-000. You may visit FERC’s website at www.FERC.gov and enter this docket number to follow the AIM Project.

In August, FERC staff issued its Draft Environmental Impact Statement (DEIS) (pdf, 20.7 MB) for the AIM Project. Reaching this significant regulatory milestone in this timeframe is great news for energy consumers in the Northeast and for our economy.

Based on this comprehensive analysis, FERC staff “determined that construction and operation of the Project would result in some adverse environmental impacts but most impacts would be reduced to less-than-significant levels.” Among the “principal reasons” cited in this comprehensive analysis are:

  • 93 percent of the project’s facilities “would be within or adjacent to existing rights-of-way” 
  • 70 percent of the project’s facilities “would replace existing Algonquin pipelines within existing rights-of-way”
  • Algonquin “would minimize impacts on natural and cultural resources during construction and operation” through specific plans to mitigate impacts

In January 2015, the New York State Department of Environmental Conservation (NYSDEC) is providing a public comment period on the applications for the Air Title V permits, 401 Water Quality Certification, Protection of Waters permit, and Freshwater Wetland permit related to the modifications at the Stony Point and Southeast compressor stations and pipeline construction within New York State.  Algonquin’s applications as filed with NYSDEC are available here:

The draft Title V permits and Permit Review Reports from NYSDEC website are available here:

From June 2013 through February 2014, Algonquin participated in FERC’s “Pre-file” process, conducting a series of activities prior to filing the formal application. During the Pre-file process, Algonquin held a number of meetings with landowners, public officials, government agencies and community members to provide information and gather input on the AIM Project. The Pre-file docket number was PF13-16-000.


  • Construction of approximately:
    • 20.1 miles of 42-inch diameter mainline take-up/relay and new pipeline in Connecticut and New York (includes a new 0.7 mile horizontal directional drill crossing of the Hudson River in New York);
    • 9.1 miles of 16-inch diameter take-up/relay pipeline in Connecticut;
    • 1.3 miles of 12-inch diameter loop pipeline in Connecticut;
    • 2.0 miles of 36-inch diameter loop extension pipeline in Connecticut; and
    • 5.1 miles of new 16-inch and 24-inch diameter lateral pipeline in Massachusetts, referred to as the West Roxbury Lateral Project. More information on the West Roxbury Lateral is available here.
  • Addition of six new compressor units, for a total of 81,620 additional horsepower, at five existing compressor stations in New York, Connecticut and Rhode Island
  • Modification to an existing compressor station in Connecticut
  • Construction of one new meter station in Connecticut and two new meter stations in Massachusetts
  • Modifications to existing meter stations in New York, Connecticut and Massachusetts

We anticipate placing the AIM Project fully into service in November 2016.
