Background Information


The CPUC is prepared an Environmental Impact Report (EIR) for the Lakeview Substation Project, and during the process requested comments on the scope and content of the EIR. SCE seeks a permit to construct (PTC) the Lakeview Substation, which includes the following major elements:

  • Construction of a new 115/12 kV substation (Lakeview Substation). The Lakeview Substation would be an unattended, automated, low-profile substation constructed and operated on an approximately 5.4-acre site in the unincorporated Riverside County community of Lakeview;
  • Installation of two new 115 kV subtransmission source line segments to connect the proposed Lakeview Substation to the existing Valley-Moval 115 kV subtransmission line. One segment would be approximately 1.8 miles in length to form the new Valley-Lakeview 115 kV subtransmission line; the other would be approximately 1.5 miles in length to form the new Lakeview-Moval 115 kV subtransmission line.;
  • Construction of two new underground 12 kV distribution getaways;
  • Installation of telecommunications facilities at the proposed Lakeview Substation, including telecommunication cable (overhead and underground) to connect the proposed Lakeview Substation to the SCE telecommunications network; upgrades to the telecommunications equipment at various substations; installation of telecommunication cable at the existing Alessandro Substation; and
  • Decommissioning of two existing substations: the Nuevo Substation and the temporary Model Pole Top Substation.

The purpose of the Proposed Project is to serve the current and projected demand for electricity, and enhance reliability and system operational flexibility in the developing areas of Lakeview, Nuevo and adjacent areas in unincorporated western Riverside County.
