The project will promote California clean energy consumption in renewable wind, solar and geothermal energy sources by 2012, during expected project completion. The renewable energy sources via Imperial Valley will be transported to electricity customers throughout San Diego, a plan that will reduce energy bills and provide hundreds of jobs in the community. The ‘superhighway’ is expected to carry at least 1000 megawatts of renewable energy in the 500-kilovolt grid, powering up to 650,000 homes.
