FERC authorizes 1st stage of TransCanada pipeline company's Northeast expansion

The Federal Energy Regulatory Commission granted authorizations to Portland Natural Gas Transmission System LP for the first phase of a three-phase natural gas pipeline system expansion in New England.

FERC issued an order amending Natural Gas Act authorizations and a presidential permit that allowed Portland Natural Gas Transmission System, or PNGTS, which is majority owned by TransCanada Corp.'s TC PipeLines Intermediate LP, to operate phase I of its Portland XPress project. The commission issued the order on Oct. 26.

Phase I required FERC to increase the certificated gas transportation capacity on the PNGTS wholly owned system from Pittsburg, N.H., to Westbrook, Maine, by 39,841 Mcf/d and the certificated capacity on the system it jointly owns with Maritimes & Northeast Pipeline LLC from Westbrook to Dracut, Mass., by 1,641 Mcf/d. The changes in authorizations also allow PNGTS to increase the import and export capacity at border crossing facilities near Pittsburg on the international border with Canada.

PNGTS applied for the first phase of the project in April. The first two phases do not involve construction. The third phase will consist of a new 6,300-horsepower compressor unit at a compressor station in York County, Maine, and modifications to infrastructure at the Westbrook compressor station in Cumberland County, Maine, and the Dracut metering and regulating station in Middlesex County, Mass.
