Riverside Transmission Reliability Project (RTRP)

Riverside Public Utilities (RPU) is proposing the Riverside Transmission Reliability Project (RTRP), which will provide needed energy resources to the city, while improving service reliability for all our customers. See a list of RTRP meeting summaries, documents and links.

On April 2, the California Public Utilities Commission (CPUC) released its Draft Subsequent Environmental Impact Report (EIR) for the Riverside Transmission Reliability Project. In keeping with the open, public nature of this process, the CPUC is now soliciting public comment on the Draft Subsequent EIR for RTRP through May 17, 2018.

The Draft Subsequent EIR is available to view on the CPUC website: http://www.cpuc.ca.gov/environment/info/panoramaenv/RTRP/index.html

Please consider submitting a comment letter before May 17, 2018 to the CPUC to express support of the RTRP Hybrid Proposal/Revised Project and its importance to Riverside’s public safety and economic future.  Linked below is a sample comment letter template for your convenience.

Comments on the Draft Subsequent EIR can be submitted in the following ways:

  1. By sending an email to the project email: riversidetrp@panoramaenv.com
  2. By sending a fax to (650) 373-1211

Letters must be submitted by May 17, 2018 in order to be included in the official record.

About the Project

The proposed RTRP would include the construction of a new double-circuit 230-kilovolt (kV) transmission line, a new 230/69 kV electrical substation, and new 69 kV subtransmission lines. The new 230 kV transmission line would connect the proposed substation, located on RPU-owned land near the northeast corner of Wilderness Avenue and Ed Perkic Street, to existing 230 kV transmission lines owned by SCE. Six new 69 kV subtransmission lines would also connect the proposed substation to RPU's electrical system.

The planned upgrades to our energy delivery system will eliminate obsolete equipment, help modernize our local energy delivery infrastructure, and help increase the energy efficiency and reliability of Riverside’s vibrant southwestern neighborhoods.

Proposed Project Map with Hybrid Alternative


Why is the RTRP needed?

Currently, all of RPU's imported energy comes through a single power connection from Southern California Edison's (SCE) Vista Substation, located in the city of Grand Terrace. Through that connection, only a certain amount of energy, 557 megawatts (MW), can reach the city.

If the electrical needs of RPU customers exceed that amount of energy, there is not any way to bring additional power into Riverside, as there are no other outside connections. While over the past ten years RPU has built a number of power generation plants within the city that can help supply extra energy in time of peak demands and emergencies, they do not provide reliable, long-term solutions to the city's capacity shortage, nor will they be enough to meet current and projected energy load growth.

The RTRP would create a second connection to outside power lines, and a second substation, that would reduce dependence on a single substation and connection, increase the amount of energy RPU could import, and provide greater flexibility to expand our energy delivery system to meet Riverside's growing energy needs well into the future.
