Proposed Portland XPress Project

More energy for New England

Portland Natural Gas Transmission System (PNGTS) is proposing Portland XPress to increase New England’s supply of energy without construction of new underground facilities. Added to existing capacity, Portland XPress will be capable of transporting 0.2 billion cubic feet a day (Bcf/d) to areas where it is in great demand.

This increase in much-needed natural gas access for New England will be achieved via modifications to the existing compressor station in Westbrook Maine and horsepower addition to the existing compressor station in Eliot, Maine. Both sites are jointly owned by PNGTS and Maritimes and Northeast Pipeline (MNE).
