The southwestern portion of Riverside County that includes the cities of Temecula and Murrieta has experienced rapid industrial and residential growth over the past several years. The Southern California Association of Governments forecasts that over the next 20 years, the city of Temecula will have a population increase of 22,880, resulting in roughly 10,630 new residential units. Due to this expected growth, Southern California Edison’s (SCE) current forecast shows the increased demand for electrical service would exceed the designed operating limits of the existing distribution facilities serving this area as early as the summer of 2010, creating a need for increased load.
SCE is proposing to build a new substation that will maintain electrical system reliability and serve the projected increase in demand in Temecula and Murrieta as well as the new developments of Roripaugh Ranch, Rancho Bella Vista and Johnson Ranch in adjacent unincorporated Riverside County.
