Notice of Staff Workshop on
Clarification of Data Requests, Data Responses
Issue Resolution and Project Schedule for the
Abengoa Mojave Solar project

The California Energy Commission staff will conduct a workshop for the proposed Abengoa Mojave Solar project to discuss the clarification of staff's data requests, applicant's expected data responses, work towards resolving outstanding issues and discuss project scheduling. All interested agencies and members of the public are invited to participate.

The workshop will be held:

FRIDAY, January 15, 2010
Beginning at 10:00 AM

A lunch break will be scheduled
from 12:00 PM to 1:00 PM

California Energy Commission
Hearing Room B
1516 9th Street
Sacramento, CA 95814-5512
(Wheelchair Accessible)

Call-in Number (toll free): 1-888-913-9966 (pass code: 14037)


The purpose of the workshop is to allow staff, the applicant, interested agencies, and the public to ask for clarification of staff's outstanding data requests and discuss the applicant's responses (expected receipt in late December). The workshop will also focus on resolving project issues and the project schedule. Subjects to be discussed include: Air Quality, Biological Resources, Cultural Resources, Geology, Hazardous Materials, Land Use, Public Health and Soil & Water Resources. Other technical areas of the data requests may be discussed as necessary.

The status of the proposed project, copies of notices, an electronic version of the AFC, and other relevant documents are also available on the Energy Commission's Internet web site at:

Project Location

The proposed project site is approximately nine miles northwest of the town of Hinkley in unincorporated San Bernardino County, approximately halfway between the city of Barstow and Kramer Junction (Highway 395 / Highway 58 junction). Project access is provided by Harper Lake Road, which is located approximately twenty miles west of Barstow along the Highway 58 corridor. The project site is approximately six miles north of where Harper Lake Road intersects with Highway 58. The existing Solar Electric Generating Stations VIII and IX facilities, owned by NextEra™ Energy Resources, are located immediately northwest of the project site. The project site is comprised of private property that was historically used as the Lockhart Ranch complex.

Project Description

The proposed AMS project is a solar electric generating facility with two units on separate solar fields totaling approximately 1,765 acres. An additional 81 acres shared between the units would be utilized for improvements designed for receiving and discharging offsite drainage.

The project would utilize solar parabolic trough technology to activate a heat transfer fluid, which, when heated, is used to create steam that is used to drive steam turbine generators. The sun would provide 100 percent of the power supplied to the project. The project would have a combined nominal electrical output of 250 megawatts (MW) from twin, independently-operable solar fields, each feeding a 125-MW power island. Natural gas from an adjacent pipeline will be used for the project's ancillary equipment, such as the auxiliary boilers. Each power island would also contain a diesel engine-driven firewater pump for fire protection and a diesel engine-driven backup generator for power plant essentials.

The AMS project proposes to connect to Southern California Edison Company's Kramer-Cool Water 230-kV transmission line which is adjacent to the southern border of the proposed project site. All project-related transmission facilities would be within the project boundaries except the connection to the existing transmission line adjacent to the site. The AMS project proposes to use wet cooling towers for power plant cooling and owns or has rights to adjudicated water rights to the Harper Valley Groundwater Basin for this purpose. This groundwater is considered brackish and/or not suitable for municipal supply or other potable uses. Water from onsite groundwater wells would be treated and used for the cooling tower makeup, process water makeup, and other industrial uses such as solar collector array washing.

If approved, construction of the generating facility, from site preparation and grading to commercial operation, is expected to take place from the fourth quarter of 2010 to the fourth quarter of 2012 (24 months total). If approved, the applicant anticipates that the project would be on line and in commercial service by the fourth quarter of 2012.
