Riverside Transmission Reliability Project (RTRP)

The Riverside Transmission Reliability Project (RTRP) provides Riverside with a critical second connection to the California grid. Riverside needs additional power capacity to serve existing and projected electrical demand and avoid blackouts. Show your support.

FAQ

Answers to the questions you may have about RTRP.


 

Why is it important?

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.
