DRA represents ratepayers in transmission proceedings to determine if an electrical corporation satisfies the fundamental requirement for all Certificate of Public Convenience and Necessity (CPCN) applications and that it makes a “showing that the present or future public convenience and necessity requires or will require such construction.”
In CPCN proceedings for major transmission lines, DRA traditionally focuses on issues relating to the determination of “need” for a proposed project, including cost-effectiveness, long-term planning, reliability requirements, and compliance with state policy and related CPUC directives.
Statewide Transmission Issues
Rule 21- Distributed Generation Interconnection Rules
The CPUC is examining the need to update Rule 21 due to the recent increase in the number and types of requests to interconnect within the state's network.
Pacific Gas and Electric Company (PG&E)
In December 2010, PG&E submitted to the CPUC an Application requesting a Permit to Construct the Shepherd Substation Project, which would result in a new 135 MW substation near Clovis, California.
Southern California Edison (Edison)
Edison claims that the Alberhill project is needed to address future overload of the existing two 500 kV/115 kV transformers in the Valley Substation that feed the Valley South 115 kV system due to increased electoral demand on the Valley South 115 kV System.
Edison is seeking a Certification of Public Convenience and Necessity (CPCN) from the CPUC to construct the Devers Palo Verde #2 transmission project, located in Riverside County, California - estimated to cost customers approximately $945 million.
In June 2007, Edison filed an Application with the CPUC to construct Segment 4-11 of the Tehachapi Renewable Transmission Project. In November 2011, the CPUC granted Chino Hill’s motion to stay the construction of Segment 8A, which traverses that community.
San Diego Gas & Electric (SDG&E)
SDG&E requested to combine over 70 existing use permits and easements into one master permit for project costs of more than $400 million, including distribution line facilities, access roads, and other ancillary and appurtenant facilities within Cleveland National Forest (CNF).
SDG&E requested the CPUC to allow it to enhance the South Orange County transmission and substation infrastructure, claiming that the project would increase electric network reliability and reduce the risk of a potential system-wide outage in the South Orange County area.
