Abstract. Selected solar-hybrid power plants for operation in base-load as well as mid-load were analyzed regarding supply security (due to hybridization with fossil fuel) and low CO2 emissions (due to integration of thermal energy storage). The power plants were modeled with different sizes of solar fields and different storage capacities and
