TL 6931 Fire Hardening / Wind Interconnect Project

(Application No. A.12-12-007 - closed)

Last Update: March 18, 2014 – Commission Order of Dismissal of Application 12-12-007 (see Other Documents Available below)


Welcome to the California Public Utilities Commission (CPUC) website for the environmental review of the proposed construction of the San Diego Gas & Electric (SDG&E) Transmission Line (TL) 6931 Fire Hardening / Wind Interconnect Project located in southeastern San Diego County, California. An application for this project was submitted to the CPUC on December 13, 2012 (Application A.12-12-007). This site provides access to public documents and information relevant to the California Environmental Quality Act (CEQA) review process.


SDG&E filed an application for a Permit to Construct the TL 6931 Fire Hardening / Wind Interconnect Project with the CPUC. The CPUC is the CEQA lead agency for this project. The project proposes to fire harden 5.2 miles of the existing 69 kilovolt (kV) wood pole power line (TL 6931) as well as provide a new 138 kV generation interconnection circuit to Boulevard East Substation. The project is needed to fire harden existing facilities in a high fire risk area of eastern San Diego County. As proposed by SDG&E, the project would fire harden the existing system by replacing the existing 69 kV wood pole structures with steel poles that include 138 kV class insulators and vertical spacing. The proposed project would also provide the interconnection facilities for the Shu’luuk Wind Project proposed on the Campo Indian Reservation, if approved. If not approved, this project would allow a vacant position for the addition of a second circuit when needed in the future. The environmental review for the Shu’luuk Wind Project is in process and is being conducted by the Bureau of Indian Affairs (see related links).

The proposed project is located south of I-8 and Old Highway 80 and traverses the Live Oak Springs and the Boulevard community areas in southeast San Diego County, California, approximately 10 miles north of the United States-Mexico border, 15 miles west of the Imperial County border, and 50 miles east of downtown San Diego. The location of the proposed project is shown in the Project Location Map.
