Supplemental information
The following changes were made on December 12, 2009: * CUT Fairmont Wind: While Fairmont has strong technical potential for wind development, there is a lack of commercial interest in developing projects in the area. In order to align Black & Veatch and commercial interest for the area, Black & Veatch reassessed the CREZ. The reassessment focused on proximity of projects to the Antelope Valley Poppy Reserve, residential encroachment and land ownership parcelization. As a result of the reassessment, Black & Veatch decided to cut four projects, representing 668 MW. These projects are largely adjacent to the Poppy Reserve, but also include one project further south that would be difficult to develop due to parcelization and residential encroachment. In addition to the project cuts, associated gen-ties were removed and the CREZ boundaries reshaped. * CUT Tehachapi Wind: Two projects in the Tehachapi CREZ were very near the Antelope Valley Poppy Reserve and were cut for many the same reasons as the projects in the Fairmont CREZ. These two projects represented 412 MW of wind capacity. In addition to the project cuts, associated gen-ties were removed and the CREZ boundaries reshaped. * CUT Palm Springs Wind: The Palm Springs CREZ includes a large amount of existing wind capacity, but over 700 MW of additional capacity was identified in RETI Phase 1. The wind industry has suggested that only 200-300 MW of additional wind are likely to be developed on the remaining land due to urban encroachment and significant siting constraints. These factors were not considered in RETI Phase 1. Four projects were cut from the Palm Springs CREZ as a result of further review. The projects were cut due to county setback requirements from two highways in the area, and agreements with two organizations in the area for a moratorium on wind development. As a result, the CREZ was cut from 769 MW to 332 MW. In addition to the project cuts, associated gen-ties were removed and the CREZ boundaries reshaped. * ADD new Westlands Solar CREZ: A new solar CREZ has been identified on the Westlands Water District property in the Central Valley. This CREZ is in a moderate solar area, but more importantly it consists of disturbed agricultural land and is adjacent to existing transmission. This CREZ will be up to 5000 MW. * ADD to Owens Valley Solar CREZ: Inyo County has requested consideration of additional lands for renewable energy development based on recently expressed commercial interest in the area. Black & Veatch had originally screened many solar sites in Inyo County due to lack of commercial interest and relatively poor economics compared to solar CREZ further south. Black & Veatch has added project some sites back to the analysis that were previously cut. The most economic projects adjacent to the existing CREZ (and existing transmission) were added. The additions increase the size of the Owens Valley CREZ from 1400 MW to 5000 MW. These new project sites are primarily located on or near Owens Dry Lake. Due to water diversions started decades ago, LADWP dried up the lake and is now responsible for extensive dust mitigation activities on the lake. LADWP has announced a 50 MW solar pilot project at the lake to test the ability of solar to control dust emissions.
