South Orange County Reliability Enhancement (SOCRE) Project
To improve safety and reliability for South Orange County’s electric utility customers, SDG&E plans to upgrade the decades-old lines, poles and substations within the cities of:
San Juan Capistrano
Unincorporated areas of Orange County
Rebuild the substation in San Juan Capistrano that was last renovated in the 1950’s;
Upgrade the transmission lines from 69kV and 138kV to 230kV in order to provide the electric reliability needed today; and
Replace existing structures with taller new steel poles, which enhance safety and reliability.
- Improves reliability to existing electric system
- Modernizes electric transmission system and replaces outdated equipment
- Meet current and future energy needs of local home and business demands
- Allows for operating flexibility
- Meets federal reliability standards
What to Expect
Minimize community impacts.
The four to five-year construction project will be phased in order to minimize community impacts as much as possible. SDG&E and contract crews will perform the majority of the work during normal business hours, Monday through Friday. Should changes to this schedule be necessary, SDG&E will notify the local residents and businesses as well as the City and other appropriate agencies.
Maximize communication with community.
SDG&E will contact all affected community members through a variety of communications means such as US Mail, email, door-to-door outreach and news media.
Residents near the substations and transmission corridors may be subjected to temporary construction-related disturbances such as noise, dust, and traffic interruption. SDG&E will notify local residents in advance as much as possible and be available to answer questions.
Construction started at the end of 2017 on the reconstruction of the San Juan Capistrano Substation and is the beginning of the four to five-year construction schedule. The project will begin with the reconstruction of the San Juan Capistrano substation. In 2018, workers will also begin removing the existing transmission structures and replace them with upgraded, modern structures.
|2012 – 2017||Project Permitting|
|2017 – 2021||Rebuild SJC Substation|
|2017 – 2021||New transmission lines - Phased completion|
|2017 – 2021||Replace existing structures with taller new steel poles|
On December 15, 2016, the CPUC approved SDG&E’s ‘Preservation Alternative’ for the SOCRE project. As conditioned in the approval, this alternative requires SDG&E to retain and restore the former utility structure located on Camino Capistrano.
