The Eldorado-Ivanpah project will consist of several components, including a new 220/115 kilovolt Ivanpah substation in eastern San Bernadino County; an upgrade of 36 miles of transmission line between the new substation and the Eldorado substation in Clark County, Nevada; installation of telecommunication infrastructure; and system upgrades to ensure reliability.
The upgrade will create added transmission capacity that could be used by proposed solar energy projects in the area. The transmission line and substation will be constructed within an existing designated utility corridor.
The BLM issued a Record of Decision on the proposal on May 25, 2011. The applicant, Southern California Edison, is also seeking approval from the California Public Utilities Commission.
