High Desert Power Project Fact Sheet

Docket Number: 97-AFC-1

Applicant: High Desert Power Project, Limited Liability Company.

Project Co-Sponsors: Inland Energy - Newport Beach, California
Constellation Power Development - Baltimore, Maryland
Project Location: The proposed project will be located on a 25 acre site within the northwest corner of the city of Victorville, on a portion of the Southern California International Airport (SCIA), formerly George Air Force Base. Please see maps.
Project Cost: $250 to $350 Million. The project will contribute to the local economy by creating 350 construction jobs and 20-25 permanent jobs depending on plant configuration.
Project Licensing: Application for Certification filed June 30, 1997. The Energy Commission licensing process normally takes about one year but can be delayed by applicant request or by the Commission seeking additional information. Please see schedule.
Project Construction: If project is approved, constuction starts in 2000.
Commercial Operation: 2001 to 2002 (depending on configuration and construction start date).
Product Sales: Electrical energy produced from the proposed merchant power plant will be sold in California's newly created electricity market pursuant to sales agreements with municipalities or other customers. The project may be modified in the future to provide steam, hot water, or chilled water to other industrial operations at the SCIA site.
Project Configuration: The applicant has identified two alternative natural gas-fired design configurations: two combined cycle configurations rated at 720 MW and 678 MW, respectively.
Technology: The first combined cycle configuration will consist of three "F" class combustion turbines (160 MW each) and three steam turbines (86.5 MW each), and the second combined cycle configuration will consist of two "G" class combustion turbines (236 MW each) and two steam turbines (115 MW each).
Components: Other major components include water treatment equipment, inlet air evaporative coolers, heat recovery steam generators, steam turbines, cooling towers, selective catalytic reduction (SCR) and aqueous ammonia storage and handling equipment, exhaust stacks, continuous emission monitors, control room and administrative building, and step-up transformers.
Operational Service: The project will provide intermediate baseload service to the California electricity system.
Transmission Line: A new electric 230 kilovolt switch yard will be constructed on the eastern end of the project site. A 7.3 mile transmission line will need to be built to connect the project with the 230 kV Victor Substation. The line routing will follow existing transmission line corridors where possible. The line will be configured to minimize electromagnetic fields (EMF). New circuit breakers would need to be added at the Victor Substation.
Fuel: A 2.75 mile natural gas pipeline will be constructed by Southwest Gas Company to provide fuel for the project.
Water Supply: Potable water will be provided by the Victor Valley Water District, and will enter at the southeast corner of the site. The applicant has examined two sources of cooling water for the combined cycle configurations: ground water from future wells to be drilled in the area, or from the Mojave River Pipeline Project.
Emission Controls: A dry low nitrogen oxide (NOx) combustion technology will be used on the simple cycle configuration to reduce NOx emissions from the combustion process to 9 parts per million by volume dry (ppmvd), or less, at 15 percent oxygen. The combined cycle configurations NOx emission will be controlled with the dry low NOx combustion technology and selective catalytic reduction (SCR) to 2.5 ppmvd, at 15 percent oxygen.
Waste Water: The applicant is proposing a crystallization process to produce a solid waste.
