LCG, May 18, 2026--The U.S. Secretary of Energy today issued an emergency order to address critical grid reliability issues in the Midwest anticipated this summer. The order is in effect beginning on May 19, 2026, through August 16, 2026. The emergency order directs the Midcontinent Independent System Operator (MISO), in coordination with Consumers Energy, to ensure that the J.H. Campbell coal-fired power plant (Campbell Plant) in West Olive, Michigan shall take all steps necessary to remain available to operate and to minimize costs for the region.

LCG, May 14, 2026--The U.S. Environmental Protection Agency (EPA) announced today that it is proposing a rule to revise wastewater limits, known as effluent limitations guidelines (ELG), for steam electric power plants that will help improve grid reliability and lower electricity prices while continuing to support clean and safe water resources. If finalized, the EPA's proposal is estimated to reduce electricity generation costs by as much as $1.1 billion annually, which could provide cost-savings to American consumers.

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.
