Project Details

  • Operator: TC Energy[2]
  • Owner: Enbridge (38.89%)[2]
  • Capacity: 210 million cubic feet per day[3]
  • Length: 188 miles / 302.6 km[3]
  • Diameter: 24-inches[3]

  • Start Year: 1999

Background

The Portland Natural Gas Transmission System is a 295-mile interstate natural gas pipeline system originating at TransCanada's TQM pipeline at the Canadian border, shares facilities with the Maritimes and Northeast Pipeline from Westbrook, ME to Dracut, MA where it ultimately connects with the Tennessee Gas Pipeline System. The pipeline has a capacity of 168 million cubic feet per day at the Canadian border and increases to 210 million cubic feet per day from Westbrook, ME to Dracut, MA.[2]

Expansion Projects

Westbrook Xpress Project, Phase 2

The expansion project does not involve adding any additional miles of pipeline. The increased transmission capacity will effect New Hampshire and Maine, USA and Quebec, Canada.[4]

According to the U.S. Energy Information Administration, as of April 2021 the project was under-construction.[5]

Westbrook Xpress Project, Phase 2 Project Details

  • Operator: Portland Natural Gas Transmission System[4]
  • Owner:
  • Capacity: 63 million cubic feet per day (MMcf/d)[4]
  • Length: 0.0 new miles of pipeline[4]
  • Status: Construction[5]
  • Start Year: 2021[4]

Portland Xpress Expansion Project

The expansion project will add an additional compressor station to the pipeline, resulting in additional transmission capacity. The increased transmission capacity will effect New Hampshire and Maine, USA and Quebec, Canada.[4]

According to the U.S. Energy Information Administration, the project entered partial service in August of 2020, with full service by the end of 2020.[6]

  • Operator: Portland Natural Gas Transmission System[4]
  • Parent Company:
  • Capacity: 24 million cubic feet per day (MMcf/d)[4]
  • Length: 0.0 new miles of pipeline[4]
  • Status: Operating[6]
  • Start Year: 2020[4]
