CPUC Approves PPAs between SDG&E and Soitec for 155 MW of Solar CPV Projects
LCG, November 17, 2011--The California Public Utilities Commission (CPUC) approved last Friday Power Purchase Agreements (PPAs) between San Diego Gas and Electric (SDG&E) and Soitec Solar Development, LLC, a subsidiary of Soitec. The PPAs are associated with five solar power projects that have a combined electric generating capacity of 155 MW. The CPUC also approved an option agreement for the right of SDG&E to purchase additional capacity from Soitec.
The five solar projects will employ Soitec's Concentrix™ concentrator photovoltaic (CPV) technology and are located in San Diego County, California. Soitec claims that its CPV technology can achieve a module efficiency that exceeds 30%, which is substantially greater than traditional solar PV modules that do not concentrate the sun's rays.
The Soitec technology uses Fresnel lenses to concentrate sunlight onto high-efficiency, triple-junction solar cells (GaInP/GaInAs/Ge) in which three different types of solar cells are stacked on top of one another. Each cell type is designed to convert a certain range of the solar spectrum: short wave radiation, medium wave radiation and infrared. The solar modules that incorporate the Fresnel lenses and solar cells are mounted on a two-axis tracking system that follows the sun throughout the day.
The CPV modules will be manufactured in a new Soitec factory planned for the San Diego area.
California passed a Renewable Portfolio Standard (RPS) that requires utilities to increase their electric supply procurement of eligible renewable generating resources, including a target requirement of 33 percent in 2020.
