This is the bird killing plant, isn’t it?
Actually, that’s the Ivanpah Solar Thermal Plant (rather than photovoltaic cell plant), which is in the Mojave Desert close to Las Vegas. Solar thermal plants use heat derived from the sun to create steam, which is then used to turn turbines to generate AC power
This new one is in the Sonoran Desert. Photovoltaic cells generate DC power, and there are going to be inherent losses due to needing to invert the DC power to AC for transmission.
