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 Transmission Line. An application for this project was submitted to the CPUC on October 9, 2007, (A.07-10-005). This site provides access to public documents and information relevant to the CEQA review process.

Background

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

The TE/VS project is necessary in order to

  1. Provide a transmission interconnection from the propsed Lake Elsinore Advanced Power Storage (LEAPS) hydroelectric facility to the transmission systems of Southern California Edison (SCE) and Southern Diego Gas & Electric (SDG&E);
  2. Interconnect the SCE and SDG&E transmission systems and facilitate wholesale bulk power transfers between those systems and from neighboring areas and those systems.

The TE/VS 500kV Transmission Line, as proposed by TNHC will be a 500 kV alternating current regional interconnection transmission line with a nominal design capacity of 1,000 MW. The transmission line will be approximately 30 miles in length and will extend from the proposed LEAPS facility in Lake Elsinore, southward to SDG&E's existing 230kV Taega-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 will be between SDG&E's existing Talega and Escondido substations at a new substation in the vicinity of Camp Pendleton. The interconnection with SCE's network will be a t a point between SCE's Valley and Serrano substations at a new substation in the vicinity of Lee Lake. In addition to the improvements described above, TNHC's LEAPS and TE/VS transmission line interconnect will require numerouse upgrades to the networks of SDG&E and SCE.

Application and Proponent's Environmental Assessment (PEA)

The application and the Draft PEA for the TE/VS project were filed with the CPUC on October 9, 2007. The documents may be viewed here. The CPUC sent a comment letter on the Draft PEA on November 16, 2007. The applicant has been revising the PEA and will file a final version of the PEA to the CPUC in February 2008.
