The U.S. Forest Service has blessed San Diego Gas & Electric's proposed $1.9 billion, 120-mile Sunrise Powerlink transmission line, which the utility says will increase the reliability of the power grid and transport renewable energy such as solar, wind and geothermal power from remote areas in southern California's Imperial Valley to residences and businesses in the San Diego region. When completed in 2012, the 500kV Sunrise Powerlink electric superhighway" will have the capacity to carry at least 1,000mW of clean power, or enough energy for 650,000 homes. Details
