The Federal Energy Regulatory Commission on Sept. 30 issued a final environmental impact statement on the Jordan Cove liquefied natural gas project in Oregon, with that project to be supplied with electricity from a new power plant nearby.
In May 2013, Jordan Cove Energy Project LP filed an application for its liquefaction project with FERC under Section 3 of the Natural Gas Act (NGA). Pacific Connector Gas Pipeline LP in June 2013 filed its companion application with the FERC for the supply pipeline to Jordan Cove’s liquefied natural gas (LNG) terminal under Section 7 of the NGA.
- Jordan Cove seeks authorization to construct and operate a new LNG export terminal in Coos County, Oregon. The terminal would be capable of receiving natural gas, processing that gas, liquefying it into LNG, storing the LNG, and loading the LNG onto vessels at its marine dock. Jordan Cove indicated that it could receive a maximum of 1.03 billion cubic feet per day (Bcf/d) of natural gas from Pacific Connector and produce a maximum of 6.8 million metric tons per annum (MMTPA) of LNG.
- Pacific Connector seeks a Certificate of Public Convenience and Necessity to construct and operate a new 232-mile-long, 36-inch-diameter natural gas transmission pipeline, crossing through Klamath, Jackson, Douglas, and Coos counties, Oregon. The pipeline would be designed to transport natural gas from interconnections with the existing Ruby Pipeline LLC and Gas Transmission Northwest LLC (GTN) systems near Malin, Oregon.
The proposed action analyzed in this final EIS includes the activities outlined in Jordan Cove’s and Pacific Connector’s applications to the FERC. The commission and cooperating agencies would consider the potential environmental impacts of the applicants’ proposals as disclosed in this EIS prior to making their decisions.
The main jurisdictional facilities associated with Jordan Cove’s LNG export terminal include:
- access channel from the existing Coos Bay navigation channel, and a terminal marine slip with a berth for one LNG vessel and a dock for tug and escort boats;
- LNG loading platform and transfer line;
- LNG storage system, consisting of two full-containment storage tanks;
- four natural gas liquefaction trains;
- emergency and hazard systems, plant systems, and electrical systems;
- a utility corridor between the LNG terminal and the South Dunes Power Plant;
- a pipeline gas conditioning facility;
- the North Point Workforce Housing Complex (NPWHC); and
- other security and control facilities, administrative buildings, and support structures associated with the terminal.
The non-jurisdictional facilities associated with the Jordan Cove’s LNG export terminal would include:
- South Dunes Power Plant, consisting of a nominal 420-MW natural gas–fired combined cycle system and heat recovery steam generator units;
- Southwest Oregon Regional Security Center (SORSC); and
- other security and control facilities, administrative buildings, and support structures associated with the power plant.
The main jurisdictional natural gas pipeline facilities proposed by Pacific Connector include:
- a 232-mile-long, 36-inch-diameter welded steel underground pipeline, extending between interconnections near Malin and the Jordan Cove terminal;
- the Klamath Compressor Station, at the eastern beginning of the pipeline;
- four meter stations, including the Klamath-Beaver Meter Station and Klamath-Eagle Meter Station co-located within the Klamath Compressor Station tract, the Clarks Branch Meter Station, and the Jordan Cove Meter Station;
- five pig launcher or receiver units, co-located with other aboveground facilities;
- 17 mainline block valves (MLV); and
- a gas control communication system, including 11 radio towers, co-located at other facilities.
The non-jurisdictional facilities associated with the Pacific Connector Pipeline Project include electric lines to the meter stations and compressor station.
New gas-fired plant would supply the LNG facility with needed power
Electrical power for the LNG terminal would be provided from dedicated power generation provided by the South Dunes Power Plant. This facility would be rated at approximately 420 MW and would be an independent power generation system exclusively for the terminal and associated facilities. A PacifiCorp connection would be provided by tapping the high voltage side of PacifiCorp’s Jordan Point substation, which is currently located on the planned South Dunes Power Plant site but is planned to be relocated to a position adjacent to the Jordan Cove meter station.
The PacifiCorp 115-kV feed would be transformed to 13.8-kV distribution to provide basic “house power” to the terminal and power generation sites. The South Dunes 230-kV substation would collect power from the site generators and distribute power to the Jordan Cove Project’s 230-kV substation. Each 230-kV substation would have a 13.8-kV area distribution for lower utilization voltages and power distribution within the two process areas.
The total maximum operating load of the LNG terminal would be approximately 310 MW. This electrical load would be experienced during warm weather operations when LNG compression is required and LNG vessels are being loaded. Most of the facility’s electrical load is comprised of motors, with the largest motors (the four liquefaction loop compressor drivers) rated at approximately 65,000 hp each.
The Oregon Energy Facility Siting Council was taking comment earlier this year on a draft proposed order approving a siting certificate application for the 420-MW South Dunes Power Plant project. That docket is still open, with no final decision yet.
The applicant is Jordan Cove Energy Project LP, a wholly-owned subsidiary of Veresen Inc. The South Dunes Power Plant would be located in Coos County, approximately one mile north of the city of North Bend, Oregon, on the east side of Jordan Cove on the North Spit of Coos Bay. The project would primarily be located within a fenced area on the site of a former Weyerhaeuser linerboard facility, which was closed and then demolished.
This is a natural-gas-fueled combined-cycle plant, consisting of two 210-MW blocks, with duct-firing capability. The nominal generating capacity is 420 MW for the two power blocks combined. Each power block would consist of three combustion turbine generators, three heat recovery steam generators and one steam turbine generator. Steam produced by the heat recovery steam generators would be delivered to gas conditioning systems for the Jordan Cove Energy Project (JCEP) liquefied natural gas (LNG) terminal.
Natural gas would be provided to the proposed energy facility from two sources: the Pacific Connector Gas Pipeline (approximately 4%), and boil-off gas and flash gas (approximately 96%) from the JCEP LNG terminal. The 36-inch Pacific Connector Gas Pipeline would enter the site near the southeast corner of the boundary. Natural gas would be available on a continuous basis from both sources. The total natural gas consumption is estimated at 87 million standard cubic feet per day.
