Enhancement by Compression Project

A 'Compression ONLY' ALTERNATIVE TO
PROVIDE ADDITIONAL CAPACITY TO NYC

 
 
Iroquois Gas Transmission System, LP (“Iroquois”) is proposing a ‘compression only’ enhancement of its existing system to receive an additional 125 million cubic feet per day of natural gas at Iroquois’ interconnect with the TC Energy Canadian mainline in Waddington, NY for redelivery to New York utilities.  

The ExC Project involves the addition of compression and associated gas cooling at existing Iroquois compressor station sites only.  All new facilities will be constructed entirely within Iroquois’ existing compressor station properties. No new pipeline is proposed as part of this project.

  • Addition of ~12,000 HP of compression and gas cooling at Iroquois’ Athens, NY Compressor Station
  • Addition of ~12,000 HP of compression and gas cooling at Iroquois’ Dover, NY Compressor Station
  • Addition of ~24,000 HP of compression and gas cooling at Iroquois’ Brookfield, CT Compressor Station
  • Addition of gas cooling only at Iroquois’ Milford, CT Compressor Station
  • Installation of Emission Reduction Equipment at Project Sites
  • Proposed In-Service January 1, 2027
 

New York

  • Greater supply to NYC will help alleviate the need for gas moratoriums and benefit economic development
  • Increased supply facilitates conversions from oil heat to gas heat while supplying new construction with natural gas instead of #2 fuel oil
  • Supports the intermittency of renewable energy sources

Connecticut

  • Complements the state’s zero-carbon initiatives and pursuit of off-shore wind resources
  • Reduces price volatility and lowers fuel prices for gas and electric utilities
  • Enhances electric grid reliability and resiliency with additional compression that enables fast start and quick ramping during peak periods
 

Mutual Benefits

  • Additional capacity with no new pipeline
  • Reduction in life cycle GHG emissions and air pollution
  • Increased property tax revenue for host communities
  • Construction jobs and boost to local economy during construction
  • Project related Community Grants
 

The ExC Project filed a formal application with the FERC in late January 2020, and received approval on March 25, 2022.

The FERC, as lead federal agency, made an assessment of the project from an environmental standpoint and issued a determination that the proposed project is within the public convenience and necessity. Additional information on the FERC process can be found at www.ferc.gov and by viewing the brochure: Your Guide to Electronic Information at FERC

Upon receiving all necessary permits, including state air permits, construction activities for this project are expected to begin by fall 2025/spring 2026. These activities will include mobilization of personnel and equipment, site preparation, and installation and testing of new compressor and gas cooling facilities. Construction should be completed by January 1, 2027.
