South Dunes power plant would serve Jordan Cove LNG terminal

The Oregon Energy Facility Siting Council is considering an application for a new gas-fueled power plant that would serve the planned Jordan Coven liquefied natural gas (LNG) export facility in Coos Bay, Ore.

The Department of Energy (DOE) approved the LNG project planned by Jordan Cove Energy Project L.P. and Veresen (TSX:VSN) on March 24, saying that exporting LNG from the site would not significantly hike natural gas and electricity costs for customers in the United States.

The preliminary application was filed in January. The South Dunes power plant will be a 420-MW combined cycle gas‐fired generation station with duct‐firing capability. It will be composed of six gas turbine generators and two steam generators. The unusual configuration of the plant (six turbine generators) is required in order to ensure an uninterrupted power supply to the LNG facility.

The planned Pacific Connector Gas Pipeline would enter the South Dunes site, where there is a metering station. A gas conditioning facility, powered by steam from the power plant, will remove contaminants from the gas so that they will not foul the liquefaction equipment at the LNG facility.

The power plant will receive its natural gas fuel primarily as boil off gas from the liquefied natural gas tanks, located a mile away, through a pipeline in a shared utility corridor. A double circuit 115 kV transmission line will run the one mile from the power plant to the liquefaction facility. A single circuit 115 kV transmission line will connect the power plant to a PacifiCorp substation on the site.

The proposed construction start date for the South Dunes power plant is January 2016 and the estimated completion date is May 2018. Startup and commissioning is anticipated by November 2018.

A LNG export facility that Dominion (NYSE:D) is proposing in Maryland would also be served by a new gas-fired power plant.
