The new 69kV subtransmission line segments will provide additional connections from Riverside’s existing generation facilities to key substations to relieve the congestion (overloads) and provide sufficient power flow to meet existing electric system demand during normal and planned/unplanned outage conditions within Riverside’s electric system. In addition, the connections of the substations will allow for Riverside’s electric facilities to run effectively and efficiently. The project is designed to increase reliability and strengthen RPU’s subtransmission system.
Project construction will occur in multiple segments and will consist of the below:
Estimated Project Timelines
Mid 2019 – Early 2020
Underground conduit and structure installation.
Late 2019 – Early 2020
RPU Staging Yard construction
Early 2020 - Mid 2020
Drilled Pier Foundations for Steel Poles from RERC to Harvey Lynn Substation
Early 2021 - Mid 2022
Installation of Steel and/or Wood Poles and construction of overhead lines from RERC to Harvey Lynn Substation
Mid 2023 - Late 2024
Installation of Drilled Pier Foundations, Steel and/or Wood Poles, and construction of overhead lines from RERC to Freeman Substation.
Drilling machine utilized for the installation of drilled pier foundations
Cages installed in the ground for the drilled pier foundations
Concrete work performed for the installation of drilled pier foundations

The project is a portion of RTRP, however, construction of the 69kV lines from RERC to Harvey Lynn Substation and RERC to Freeman Substation are not dependent on Southern California Edison’s (SCE) 230kV project portion scope of work, approved by the California Public Utilities Commission (CPUC) in March 2020. The 69kV Subtransmission System Reliability project segments from RERC to Harvey Lynn and Freeman substations are necessary to improve the electric system reliability within the City. For additional information regarding RTRP, visit the RTRP page.
The project route was proposed in the Environmental Impact Report (EIR) and certified by City Council on February 5, 2013. Within the EIR, Project Alternatives related to the 69kV Subtransmission Line Routes were reviewed, evaluated and the environmentally preferred/superior low-cost alternative was recommended/approved. The following factors were considered during the process:
Significant visual impacts to designated Scenic Roadways
Significant construction impacts to traffic
Effects to existing infrastructure
Number of schools, homes, and day cares adjacent to the routes
Utilization of existing subtransmission lines

Should your landscaping be impacted during construction, all reasonable efforts will be made to restore the site to its original state.
The CPUC does not consider EMF to be an environmental issue in the context of CEQA because there is no agreement among scientists that EMF creates a health risk, and because CEQA does not define or adopt standards for defining any potential risk from EMF.
