Blythe Energy Project Fact Sheet

Docket Number: 99-AFC-8


Applicant Blythe Energy, Limited Liability Corporation
Applicant's Website www.wisvest.com
Project Owner Effective January 5, 2000, Wisvest Coporation (a Wisconsin Corporation) acquired 100 percent of the assets and rights of ownership of Blythe Energy, LLC (a Delaware Corporation). The location of Wisvest's Home Office is:
N16 W23217,
Stone Ridge Drive, Suite 100,
Waukesha, WI 53188. The Blythe office is located at:
101 East Hobsonway, Suite C,
Blythe, CA 92225.
Project Location The proposed project is located on a 76-acre site approximately five miles west of the center of the City of Blythe, near the airport.
Project Cost $250 Million (approximately). The project will contribute to the local economy by creating 250 - 400 construction jobs and approximately 20 permanent operation and maintenance jobs.
Project Licensing The Application for Certification (AFC) was filed 9 December, 1999 and was found data adequate on 22 March, 2000. The Energy Commission's licensing process normally takes about one year after the AFC has been determined to be data adequate. Western Area Power Administration (Western) has signed a Memorandum of Understanding (MOU) to work with the Energy Commission as the lead federal agency for the purposes of National Environmental Policy Act (NEPA) compliance, as well as adherence to other federal laws, regulations, and policies pertaining to the project. The licensing process can be delayed by the applicant's request.
Project Construction If the project is approved, construction would probably start in 2001.
Commercial Operation 2003 to 2004, depending on configuration and construction start date.
Product Sales Electrical energy produced from the proposed merchant power plant will be sold into Western's distribution system pursuant to sales agreements with municipalities or other customers.
Plant Configuration The applicant proposes to construct a 520 megawatt (MW) naturalgas-fired combined-cycle power plant.
Technology The combined-cycle configuration will consist of two 170 MW combustion turbine generators (CTGs), two heat recovery steam generators (HRSGs), one 180 MW steam turbine generator (STG).
Components Other major components of the proposed project include water treatment equipment, an inlet air cooling system which will be either an evaporative type or an electric chiller type using ammonia. Exhaust stacks from the HRSGs will use selective catalytic reduction (SCR), to reduce harmful emissions. SCR requires the injection of ammonia into the stack exhaust stream. The proposed power plant will use continuous emission monitors and it will be operated from the control room which will be located in the administration building.
Emission Air emissions from the combustion of natural gas in the CTGs and duct burners will be controlled using state-of-the-art combustion technology and selective catalytic reduction (SCR). To ensure that the systems perform correctly, continuous emissions monitoring (CEM) will be performed.
Operational Service The project will provide intermediate baseload service into Western's power distribution system.
Transmission Line A new 161 kilovolt (kV) electric switch yard is proposed to be constructed on the northeast portion of the parcel. This new Blythe Energy project substation will be capable of producing power at either 161kV or 230 kV, should the power grid be upgraded to 230 kV from its present 161kV. The project proposes to interconnect with the regional electric transmission grid at the Blythe substation which is located to the east of the proposed project site within about 600 feet. The Blythe power substation is owned by Western and connects five existing 161kV transmission lines serving the region. New transmission lines to be constructed as part of the project consist of ties to the existing Parker to Blythe transmission lines immediately east of the Blythe Energy Project switchyard and north of the existing Blythe substation. The tie line to the Parker - Blythe line will be about 450 feet in length. The tie line to the Parker-Headgate-Blythe line will be about 650 feet in length. The tie line connecting to the existing Blythe Substation, using the existing Parker-Blythe line, will be about 600 feet in length.
Fuel Two alternative natural gas supply pipelines are proposed. The first alternative would be an 11.5 mile pipeline which would be constructed to connect with a high pressure gas line owned by El Paso Natural Gas Company (EPNG). This line would be microbored under the Colorado River and connect to EPNG's line in Arizona. The second alternative would be a 0.8 mile pipeline which would interconnect with the high pressure natural gas pipeline owned by Southern California Gas Company (SoCalGas).
Water Supply The proposed water supply for all plant uses is groundwater that would be supplied by wells constructed on the plant site. The power plant will require approximately 2,150 gallons per minute when the plant is fully operational. The water will be recirculated through the plant an estimated 6 to 8 times for maximum efficiency of water use.
Waste Water The Blythe Energy Project will be a "zero discharge" facility with water discharge managed on-site in lined evaporation ponds comprising a total of about 16 acres. Sanitary wastewater from sinks, toilets, and other sanitary facilities will be disposed of onsite by a septic system and leach fields.
