Simulation of proposed substation facing southwest from Olsen Road towards the proposed site.

Demand for electricity in Southern California is continually increasing. SCE’s current forecast shows that projected demand for electrical service in Simi Valley, Thousand Oaks and adjacent areas of unincorporated Ventura County will exceed SCE’s operating capacity at its existing facilities as early as summer of 2011. To keep pace with growing demand, SCE is taking steps to ensure that its electrical facilities will be able to meet the anticipated demand. SCE is proposing construction of the Presidential Substation project, which will primarily consist of a new substation and a new 66 kilovolt subtransmission line route. The project would increase electrical capacity to the area, maintain system reliability and serve the area’s projected electrical demand.
