GENERAL DESCRIPTION OF PROJECT

artist

On August 10, 2009, Abengoa Solar Inc., the sole member of Mojave Solar LLC, filed an Application for Certification (AFC) for its Abengoa Mojave Solar (AMS) project. The project is a nominal 250 megawatt (MW) solar electric generating facility located near Harper Dry Lake in an unincorporated area of San Bernardino County, CA. The project is located approximately halfway between Barstow, CA and Kramer Junction, CA, and is approximately nine miles northwest of Hinkley, CA. The project is located on approximately 1,765 acres.

The project consists of well-established parabolic trough technology to solar heat a heat transfer fluid (HTF). This hot HTF generates steam in solar steam generators, which expands through a steam turbine generator to produce electrical power from twin, independently-operable solar fields (Alpha and Beta), each feeding a 125-MW power island. Each power island has a diesel engine-driven firewater pump for fire protection and a diesel engine-driven backup generator for power plant essentials. The sun provides 100 percent of the power supplied to the project through solar-thermal collectors; no supplementary fossil-based energy source (like natural gas) is used to produce electrical power.

Through a substation located on the southern edge of the site, the AMS project interconnects to the Kramer-Cool Water 230-kV transmission line, owned by Southern California Edison.

Access to the Alpha Power Block is on Harper Lake Road approximately 6 miles north of State Highway 58.

Access to the Beta Power Block is on Lockhart Ranch Road approximately 1-1/2 miles east from the Harper Lake Road and Lockhart Ranch Road intersection.

The AMS project uses wet cooling towers for power plant cooling and owns adjudicated water rights to the Harper Valley Groundwater Basin for this purpose. The Mojave Water Agency administers these water rights. The groundwater supply is brackish and therefore not suitable for municipal supply or other potable uses. The AMS project proposes to utilize 2,163 acre-feet of water per year, for 30 years. The AMS project has rights to 10,478 acre-feet of groundwater per year.


Energy Commission Facility Certification Process

The California Energy Commission is the lead agency (for licensing thermal power plants 50 megawatts and larger) under the California Environmental Quality Act (CEQA) and has a certified regulatory program under CEQA. Under its certified program, the Energy Commission is exempt from having to prepare an environmental impact report. Its certified program, however, does require environmental analysis of the project, including an analysis of alternatives and mitigation measures to minimize any significant adverse effect the project may have on the environment.
