Project Vitals

Location: Imperial Valley near the Mexican border, eight miles southwest of El Centro

Electricity Production Capacity: 200 megawatts

Company: CSOLAR Development, LLC (CACA-523359) and SDG&E Company (CACA-51645)

Acreage: 947 acres

Status: BLM approval on July 14, 2011. CSOLAR Development, LLC submitted two right-of way (ROW) applications. The first application was to construct, operate and maintain a 230 kV transmission line, and the second application was for a road ROW across Federal lands along the Westside Main Canal. The electric generating facility would connect to the Imperial Valley Substation via 230 kV transmission line and access to the facility would be along the Westside Main Canal. 

The site of the solar energy facility is located on 946.6 gross acres of privately-owned, formerly undeveloped and agricultural lands. It is located in the unincorporated Mount Signal area of the County of Imperial, approximately eight miles southwest of the City of El Centro and south of the community of Seeley. The transmission lines and access road are located within the Yuha Desert, and within BLM's Utility Corridor "N" of the California Desert Conservation Area Plan. Imperial County is located in Southern California, bordering Mexico, west of Arizona, and east of San Diego County.

The 230 kV transmission line (CACA-51645) was demolished in the fall of 2013 and the Right-of-Way (ROW) was assigned to San Diego Gas & Electric Company. This ROW is currently undergoing reclamation, re-vegetation, and monitoring.

The access road to the private land solar project (CACA-523359) is currently in use by the solar facility and will remain so for the duration of the grant.

Electrical Transmission Connection: 230 kV line crossed BLM land and interconnected with the Imperial Valley Substation.  Electricity is currently routed north along an Imperial Irrigation District transmission line.

By the Numbers:

  • The solar project generates enough electricity to power approximately 60,000 homes
  • The private land parts of the project generates an estimated $3 million in local tax revenue
  • Up to 250 construction jobs and 4-5 permanent jobs have been created
  • Photovoltaic technology is being utilized
