SDG&E CPCN South Orange County Reliability Enhancement Project
In May 2012, San Diego Gas and Electric Company (SDG & E) requested the CPUC to allow it to enhance the South Orange County transmission and substation infrastructure at an estimated cost of $400 - $600 million. SDG&E claims that the project would increase electric network reliability and reduce the risk of a potential system-wide outage in the South Orange County area. Specifically, SDG&E proposes to:
- Upgrade the 138/12kV Capistrano Substation to a 230/138/12kV substation
- Replace 138kV transmission line with a 230kV double-circuit extension
- Upgrade the Talega Substation.
SDG&E estimates that 45% of the project cost will be paid for equally by all electric ratepayers throughout California, while the remaining 55% will be paid for by SDG&E’s ratepayers. This will increase SDG&E’s rates by about 1%.
DRA Policy Position
In June 2012, DRA argued that both need and cost of the project are not adequately addressed to demonstrate benefits to ratepayers and requested the CPUC to adopt a procedural schedule that provides adequate time for discovery and analysis of the SDG&E application. Additionally, customers should not pay for a project that does not meet the reliability requirements of the North American Electric Reliability Corporation (NERC) or the Western Electricity Coordinating Council (WECC).
