  Welcome to the California Public Utilities Commission (CPUC) website for the 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 the northwest corner of Los Angeles County, California, near the cities of Bakersfield, Arvin and Tehachapi and nearby communities of Grapevine and Gorman. It would begin at the Kern River Substation located 13 miles northeast of Bakersfield, and would extend south to the Gorman Substation, about two 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 has submitted a Permit to Construct (PTC) application for the project to the CPUC on February 28, 2022. These files can be viewed by following the links below under Environmental Review.

The project will be reviewed under the California Environmental Quality Act (CEQA). The CPUC will prepare an Environmental Impact Report (EIR) as the CEQA lead agency

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.

PROJECT SCOPING: Tentatively Scheduled for Summer 2022

The public scoping period is tentatively scheduled for Summer 2022. Please check back for updates.

Project Information

Please review the following for information about the project:
  1. Kern River TLRR Project Fact Sheet

  2. Project Map


SCE is proposing to construct and operate the project. The project would be located in Kern County, to the east of the City of Bakersfield. SCE is required to file an application for a PTC with an accompanying Proponent's Environmental Assessment (PEA) with the CPUC for the project. The project would involve the rebuild of 65.3 miles of existing 66 kV subtransmission circuits by removing and replacing existing subtransmission towers and poles; removing and replacing existing conductor; installing Optical Ground Wire; and modifying existing substations facilities associated with the line.


Proponent's Environmental Assessment and Application

SCE has filed their PTC application and PEA (and appendices) on February 28, 2022. See links for review below:

The CPUC has conducted a completeness/deficiency review of the PEA from February 28, 2022 through March 29, 2022. The deficiency letter #1 and responses are provided below.
