project background
Project Background
  • SCE is proposing to construct The Eldorado-Ivanpah Transmission Project to access new solar generation near the southern California-Nevada border.
  • The Eldorado-Ivanpah Transmission Project will consist of replacing existing 115 kV line with a new double-circuit 220 kV transmission line, construction of a new 220/115 kV Substation, installation of telecom, and Light & Power to new Substation.
  • SCE filed an application in May 2009 with the California Public Utilities Commission (CPUC) for a Certificate of Public Convenience and Necessity (CPCN) for the Eldorado-Ivanpah Transmission Project.
project description substations
Project Description Substations
  • Construction of a new 220/115 kV substation (Ivanpah) approximately 7 miles west of the California/Nevada border in the Ivanpah Dry Lake area.
    • Ivanpah Substation will serve as a collector hub for the solar generation projects.
    • Designed to allow up to four 220/115 kV transformers (A-banks)
    • Initially two 220/115 kV transformers with an SPS
  • Eldorado Substation
    • Expand existing switchrack and install two new 220 kV positions at Eldorado Substation to support connection of new transmission lines
    • Remove existing 220/115 kV transformer bank at end of North 220 kV bus
project description transmission
Project DescriptionTransmission
  • Removal of approximately 35 miles of the Eldorado leg of the existing Eldorado-Baker-Cool Water-Dunn Siding-Mountain Pass 115 kV line.
  • Construction of approximately 35 miles of a new double-circuit 230 kV transmission line with bundled 1590 ACSR conductor.
    • Initially only one side of the double-circuit would be strung to support the first set of generation interconnections request
    • The new double circuit 220 kV line would be constructed in mostly existing right-of-way. Additional easements may be required due to narrow width of the existing right-of-way along portions of the route and for some line crossings
  • Re-route remaining portion of Eldorado leg of Cool Water-Baker-Dunn Siding-Mountain Pass 115 kV line into new Ivanpah Substation.
    • New Baker-Cool Water-Dunn Siding-Mountain Pass-Ivanpah 115kV line
