  Welcome to the California Public Utilities Commission (CPUC) website for environmental review of Southern California Edison's (SCE's) Transmission Line Rating Remediation (TLRR) Gorman-Kern River 66 kV (kilovolt) Project (project). The project is located in the central portion of Kern County and northwest Los Angeles County, California, near the cities of Bakersfield, Arvin and Tehachapi and near the communities of Grapevine and Gorman. The project would begin at the Kern River Substation located 13 miles northeast of Bakersfield, and would extend south to the Gorman Substation, about 2 miles east of the community of Gorman, with a branch extending east to the Banducci Substation near the City of Tehachapi; a map is provided here. SCE submitted a Permit to Construct (PTC) application for the project to the CPUC on February 28, 2022 (A.22-02-014). The PTC application can be viewed by following the links below under Environmental Review.

The CPUC will be the lead agency for review of the project in compliance with the California Environmental Quality Act (CEQA).

This website provides access to public documents and information relevant to the CEQA environmental review process. An overview of the project is provided below. For additional information on the CPUC proceeding, contact the Public Advisor's Office.
