Portland Natural Gas Transmission System (PNGTS) connects with the TQM pipeline at the Canadian border to deliver natural gas to markets in New England and Atlantic Canada in response to the growing need for transportation capacity in the region. The system provides natural gas for residential and commercial use, and electricity generating plants.

The market for natural gas in New England has been constrained by a lack of infrastructure to move natural gas, a clean, abundant and affordable fuel, to where it is needed. We are undertaking two multi-phase compression-only projects to increase New England’s natural gas supply without the need for construction outside existing facilities. These projects, Portland XPress and Westbrook XPress, valued at $130 million combined for the partnership’s proportionate share, are fully backed by fixed rate, 20+ year contracts. Earlier phases of these projects entered service in 2018 and 2019. Portland XPress Phase III went into service in November 2020 with additional phases planned to be in service in November 2021 and 2022. Together, these projects have approximately doubled the firm capacity of the PNGTS system to nearly 400,000 Dth/d.
