Imperial Valley Solar Project
(The Imperial Valley Solar (IVS) project was originally named and referred to as the Solar Two project. The name was changed to the IVS project by the applicant after the publication of the Staff Assessment/Draft Environmental Impact Statement (SA/DEIS) in February 2010.)


CASE FILE NUMBER: CACA47740

Background

Stirling Energy Systems (SES) submitted an application to the Bureau of Land Management (BLM) for development of the proposed SES Solar Two Project, a concentrated solar electrical generating facility capable of generating 750 megawatts (MW) of renewable power.  The proposed SES Solar Two Project site is located on approximately 6,140 acres of federal land managed by the BLM and approximately 300 acres of privately owned land.  

The project site is in Imperial County, California, approximately 4 miles east of Ocotillo, and 14 miles west of El Centro. Generally, the proposed site boundary is the Union Pacific Railroad on the north and Interstate 8 on the south. The eastern boundary is approximately 1½ mile west of Dunaway Road; and the western boundary is the westerly section line in Section 22 in Township 16 South, Range 12 East. An additional 125 acre construction area is located east of Dunaway Road.

The proposed SES Solar Two Project also included an electrical transmission line, water supply pipeline, and a site access road. A new 230-kV substation would be constructed approximately in the center of the project site. This new substation would be connected to the existing SDG&E Imperial Valley Substation via an approximately 10.3 mile, double-circuit, 230 kV transmission line. Approximately 7.56 miles of the new line would be constructed offsite. Other than this interconnection transmission line, no new transmission lines or off-site substations would be required for the 300 MW Phase 1 construction. The full Phase II expansion of the project, and delivery of the additional renewable power to the San Diego regional load center, would require the construction of the 500 kV Sunrise Powerlink transmission line proposed by SDG&E. The off-site 6-inch diameter water supply pipeline would be constructed a distance of approximately 3.4 miles from the Westside Main Canal to the project boundary. The water pipeline would be routed in the Union Pacific Railroad right-of-way (ROW), or adjacent to this ROW on federal and private lands. A site access road would be constructed from Dunaway Road to the eastern boundary of the project site, generally following an existing road.


The Record of Decision was signed on October 5, 2010.  This decision approved the IVS Project Agency Preferred Alternative as analyzed in the Final EIS. The 709 MW Selected Alternative will be built on approximately 6,144 acres of BLM land, although the total public land acreage to be authorized is 6,359.56 acres. To the extent the approved alternative does not progress to construction, operation, or is proposed to be changed to the extent that it appears to the BLM to be a new project proposal on the approved project site, that proposal is subject to NEPA review.
