Southern California Edison's Sandlot (formerly called Water Valley or Lockhart) Substation Project

(Application A.11-05-006, filed May 5, 2011)

Welcome to the California Public Utilities Commission (CPUC) website for the California Environmental Quality Act (CEQA) review of proposed construction of Southern California Edison's (SCE) Sandlot Substation Project. An application for this project was submitted to the CPUC on May 5, 2011 (Application A.11-05-006). This site provides access to public documents and information relevant to the CEQA review process.

Background Information

Background

SCE's application requests a Permit to Construct a new substation (Sandlot Substation) and related facilities in San Bernardino County as required to interconnect solar power generated by the 250-megawatt (MW) Abengoa Mojave Solar Project (AMSP) to the electric grid. The proposed Project includes the following major components:

  • A 220 kV substation (Sandlot Substation) to loop the AMSP into SCE's existing Cool Water-Kramer No. 1 220 kV transmission line;
  • Two generation tie (gen-tie) line connections to connect the AMSP into the proposed substation;
  • Approximately 3,000 feet of new transmission line segments (two line segments of approximately 1,500 feet each), connecting the new Sandlot Substation to SCE's existing 220 kV Cool Water-Kramer No. 1 transmission line.
  • One 12 kV distribution line to provide light and power to the proposed substation as well as temporary power for the construction of the Sandlot Substation and AMSP facilities.
  • Three fiber optic communication routes and related infrastructure to connect the proposed substation to SCE's existing telecommunications system.

Location of the Proposed Project

Mojave Solar LLC will develop the AMSP on approximately 1,765 acres of private land in San Bernardino County, California, of which the proposed Sandlot Substation would be constructed on 8-to-10 acres. Interconnection of the AMSP to SCE's adjacent power lines would occur on and adjacent to the AMSP site. The fiber-optic telecommunication system diverges from the AMSP/Sandlot Substation site into three directions covering approximately 85 miles of corridors: Approximately 31 miles of new fiber-optic cable to be installed between the proposed Sandlot Substation and the existing Tortilla Substation, located to the southeast in the City of Barstow; approximately 16 miles would be installed between the Sandlot to Kramer substations, including approximately 7 miles of which would cross BLM-administered lands within an existing transmission line corridor; and approximately 38 miles between the Kramer and Victor substations, including approximately 8.5 miles that would cross BLM lands. The Sandlot Substation site and most of the fiber optic corridors are located within unincorporated San Bernardino County. Portions of the proposed fiber optic line pass through the city limits of Adelanto, Victorville and Barstow.

Other Documents Available

Environmental impacts of the Project were analyzed in large part by the California Energy Commission (CEC) in its September 2010 Commission Decision pursuant to its licensing of the AMSP and by the U.S. Department of Energy (DOE) and the U.S. Department of the Interior Bureau of Land Management (BLM) in the Environmental Assessment (EA) prepared pursuant to these agencies' consideration of Mojave Solar LLC's applications for a loan guarantee for the AMSP and right-of-way for the installation of the approximately 17 miles of the 85-mile proposed fiber-optic telecommunication network that crosses BLM-administered lands. However, additional analysis is required of the Project (specifically the telecommunications links) to satisfy the CPUC's obligation under CEQA to consider SCE's application for a Permit to Construct. Prior analyses of Project components are summarized and incorporated by reference in the IS/MND, and access to them is provided below.
