TransCanada ready for construction on gas pipeline to serve Carty power plant

TransCanada‘s Gas Transmission Northwest LLC subsidiary filed a May 11 request at the Federal Energy Regulatory Commission for approval of a construction start on a gas lateral pipeline to serve Portland General Electric‘s new Carty power plant.

In March 2013, FERC issued a certificate of public convenience and necessity to Gas Transmission Northwest that authorized it to construct and operate the Carty Lateral Project, consisting of a new natural gas lateral pipeline and other associated facilities in Morrow County, Oregon. It will provide up to 175,000 dekatherms per day of firm transportation service to Portland General Electric’s Carty Generating Station. On Feb. 3 of this year, the commission granted Gas Transmission Northwest an extension of time, until Dec. 31, 2015, to complete these authorized activities.

The company wants, by May 18, the Director of the Office of Energy Projects to approve a construction start.

The company was approved to construct and operate approximately 24.3 miles of 20-inch diameter pipeline between its Ione Compressor Station and the Carty Generating Station. Gas Transmission Northwest would also construct and operate a tap assembly and pig launcher within the Ione Compressor Station yard or within its adjacent right-of-way and a meter station and pig receiver at the Carty Generating Station.

Portland General Electric (NYSE: POR) said April 28 in an earnings statement that construction on the Carty Generating Station is on schedule for this 440-MW, natural gas-fired baseload power plant located near Boardman, Ore. The plant is expected to be placed into service during the second quarter of 2016 at an estimated cost of $450 million, excluding allowance for funds used during construction. Carty’s gas turbine and generator have been installed and the steam turbine and steam turbine generator have been shipped. Welding on the heat recovery steam generator piping is ongoing, and the construction percentage complete is approximately 50%.
