Nocturnal electricity production under full load by means of thermal salt reservoirs

Electricity generation by the power plant each year
Heat transfer oil, heated by solar radiation, generates steam in a heat exchanger, which, as in conventional power plants, drives a steam turbine. In this way, electricity is produced by a generator, and fed into the grid. At the same time, a thermal store (salt store) is charged during the day. It ensures that electricity can still be produced after sunset.
