The 6.3-megawatt Desert Green Solar Farm, located in Borrego Springs, began commercial operations in 2015 . Prior to construction, HELIX Environmental Planning installed an exclusionary fence to safeguard two protected lizard species (flat-tailed horned lizards and Colorado Desert fringed-toed lizards) and provided biological monitoring during construction of the project. HELIX biologists, with authorizations to survey for and handle flat-tailed horned lizards, monitored the fence installation and conducted clearance surveys. In addition, HELIX monitored construction activities to help ensure compliance with project requirements. The 62-acre renewable energy facility uses more than 3,500 concentrator photovoltaic (CPV) modules, made by San Diego-based Soitec Solar Development, to boost output. San Diego Gas & Electric is purchasing this output to supply power for public consumption.
