Solar Project in Pahrump Valley Inyo County

Hidden Hills

In August 2011, BrightSource Energy filed an Application for Certification with the California Energy Commission for the development of a two 250 megawatt (nominal) solar power plants (500 megawatts nominal combined) in California’s Inyo County. If approved, the Hidden Hills Solar Electric Generating System (SEGS) will use BrightSource’s proprietary LPT solar thermal energy system and its next generation 250 megawatt solar plant design, which reduces land use by 33% or more compared to a typical photovoltaic (PV) farm and parabolic trough solar thermal plant.

The permit application before the California Energy Commission is currently in suspension for this project.

Project Overview

A 500 megawatt solar complex using mirrors to focus the power of the sun on solar receivers atop power towers.

  • Located on 3,280 acres of private land in Inyo County, CA, adjacent to the California/Nevada border, approximately 18 miles south of Pahrump, NV and 45 miles west of Las Vegas, NV.
  • The electricity generated by the two plants is enough to serve more than 178,000 homes in California during the peak hours of the day.
  • The complex will reduce carbon dioxide (CO2) emissions by more than 17 million tons over its 30 year life cycle.
  • Preliminary economic studies of the Hidden Hills SEGS project indicate that it will create more than 2,300 construction jobs at the peak of construction and approximately 100 operations and maintenance jobs.
  • Construction wages are expected to reach nearly $160 million, with total employee earnings estimated at nearly $550 million. The project will also generate over $300 million in local and state tax revenues.
