South Orange County Reliability Enhancement
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
San Clemente
Unincorporated areas of Orange County.
The Project 
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 select existing wood poles with taller
new steel poles, which enhance safety and reliability.
Reliability Benefits
Improves reliability to existing electric system
Modernizes electric transmission system and replaces outdated equipment
Meet the future energy needs of local home and business demands
Allows for operating flexibility
Meets federal reliability standards
What to Expect
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 Saturday. 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.
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.
