Welcome to the California Public Utilities Commission (CPUC) website for the California Environmental Quality Act (CEQA) review of the proposed construction of The Nevada Hydro Company Inc.'s (TNHC) Talega-Escondido/Valley-Serrano (TE/VS) 500 kV Interconnect Project. An application for this project was submitted to the CPUC on October 9, 2007 (A.10-07-001). The CPUC is preparing an Environmental Impact Report (EIR) for the TE/VS Project. The Notice of Preparation was issued on March 14, 2011.This website provides access to public documents and information relevant to the CEQA review process.

Background

TNHC has filed an application for a Certificate of Public Convenience and Necessity (CPCN) with the CPUC to construct the TE/VS 500 kV Interconnect Project. The CPUC is the CEQA lead agency for the TE/VS transmission line project.

The TE/VS 500 kV transmission line, as proposed by TNHC, would be a 500 kV alternating current regional interconnection transmission line with a nominal design capacity of 1,000 MW. The transmission line would provide a transmission interconnection from the proposed Lake Elsinore Advanced Pumped Storage (LEAPS) hydroelectric energy storage facility to the transmission systems of Southern California Edison (SCE) and San Diego Gas & Electric (SDG&E), and it would interconnect the SCE and SDG&E systems.

The transmission line would be approximately 32 miles long and would extend from the proposed LEAPS facility near the City of Lake Elsinore, southward to SDG&E's existing 230 kV Talega-Escondido transmission line in San Diego County, and northward to SCE's existing 500 kV Valley-Serrano transmission line in Riverside County. The interconnection with SDG&E would be between SDG&E's existing Talega and Escondido substations at a new substation adjacent to Camp Pendleton. The interconnection with SCE's network would be at a point between SCE's Valley and Serrano Substations, at a new switchyard in the vicinity of Lee Lake. In addition to the improvements described above, TNHC's TE/VS Interconnect Project would require numerous upgrades to the SDG&E and SCE systems.

Application and Proponent's Environmental Assessment (PEA)

In October of 2007, an application (A.07-10-005; A.09-02-12) and PEA for the TE/VS project were filed with the CPUC. However, on April 16, 2009, the Administrative Law Judge (ALJ) issued a decision dismissing the application without prejudice as a result of several deficiencies in the PEA:

Decision of ALJ Karen V. Clopton
Attachment 1 (26.4MB)
Attachment 2
Attachment 3
Attachment 4
Attachment 5

A new application and PEA were filed on July 6, 2010. This application and PEA were deemed complete by the CPUC on August 5, 2010. The CPUC acknowledged this with a letter to TNHC. On February 25, 2011, TNHC filed a revised Chapter 3 to replace the Chapter 3 submitted in the July 2010 PEA. This revised chapter and associated figures supersedes the earlier version of Chapter 3.

Public Scoping Meetings

The CPUC held two public meetings, on Tuesday, April 5, 2011 in Lake Elsinore, and on Wednesday, April 6, 2011 in Murrieta. These meetings gave the public and interested parties an opportunity to learn more about the proposed TE/VS Project and provided an opportunity for them to comment on the scope of the Environmental Impact Report (EIR) that is being prepared. Copies of the presentation and maps that were shown at the scoping meetings can be downloaded here:

Comments made at these meetings or submitted subsequently will be considered by the CPUC in defining the scope of the EIR. The comment period will extend to April 29, 2011.
