LCG, August 7, 2025--Portland General Electric (PGE) today announced the completion of three, four-hour lithium-ion utility-scale battery energy storage systems (BESS) in Oregon, adding 475 MW and more than 1.9 GWh of dispatchable capacity to serve the Portland metro area. Each of these BESS facilities can deliver power during peak demand or when other electric generating facilities are limited, which improves system flexibility, reliability and costs.

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.
