The 11,000 page Environmental Impact Report conducted by the California Public Utilities Commission favored no transmission line as its first alternative. Instead, the report recommended a mix of energy sources, including local solar generation. San Diego County is one of the sunniest counties in the country and is a favorable venue for rooftop solar voltaic generation, as pointed out in a comprehensive report discussing various energy options for the region Bill Powers' Smart Energy Solutions report . The project has also generated controversy concerning the choice of route. Rather than following roads (e.g. Interstate 8) or existing transmission lines, SDG&E originally proposed to build it in wilderness, cutting across Anza-Borrego Desert State Park and Cleveland National Forest. The route approved by the California Public Utilities Commission avoids Anza-Borrego Desert State Park, and instead traverses the Cleveland National Forest and the communities of Jacumba, Boulevard, Campo, Japatul Valley, Lyons Valley, Alpine, and Lakeside. The U.S. Forest Service is currently considering a proposed plan amendment and Record of Decision that would allow the line to cross a section of the Cleveland National Forest. The project can not be built without Forest Service approval. SDG&E has stated that the Sunrise Powerlink is expected to be in service by 2012.
