According to a study presented to the California Energy Commission July 23 by the Electric Power Group, a one-third renewable supply in 2020 in the state would be the equivalent of 26,600 non fossil-fueled MW, rising to 30,000 MW in 2030. Two-thirds of that alternative green power is needed in the Los Angeles Basin, said John Ballance, with the power group. “The transmission capacity needs to be doubled or tripled in the LA basin,” Balance said during a follow-up workshop on renewable energy at the commission. The region’s high voltage lines now can carry about 10,000 MW, he said. Meeting the increased levels of renewable loads across the state is expected to come largely from wind, followed by solar thermal plants. The break down as presented by Ballance is as follows: -Wind power: 16,000 MW; -Solar Thermal generation: 7,000 MW; -Geothermal: 3,500 MW; -Solar Photovoltaic: 2,000 MW; and -Biomass: 1,500 MW. The PV estimate, however, may be considerably off because it does not factor in the expected boom in utility-scale solar projects, including the massive ones announced by Southern California Edison and San Diego Gas & Electric. Edison proposes installing 250 MW of solar rooftop panels, largely on warehouses. The first round of installation began last week. SDG&E announced last week it planned to install 70-80 solar tracking projects over the next five years.
