    The Cerro Dominador solar power complex can supply energy 24 hours a day manageably and efficiently, combining photovoltaic energy with concentrated solar power.

    Photovoltaic Energy

    A more mature technology, already consolidated, and a shorter installation time are some of the advantages of this energy.

    How does a Photovoltaic Plant work


    • Collection of solar energy through panels that convert sunlight, through the photovoltaic effect, into constant electrical current.
    • Conversion to alternating electric current through several groups of photovoltaic inverters from the energy generated in the panels.
    • Transportation of alternating electrical energy through an electrical network distributed by the solar field, which collects the energy from each group of inverters.
    • Coordination of the energy dispatches of the concentrated solar power and photovoltaic plants through a Control Center.
    • Interconnection of the plant to the Chilean electricity grid, through a booster substation that increases the voltage up to that of the interconnection point and a sectioning substation that connects the output of the plant with the existing power lines.

    How does a Concentrated Solar Power Plant work


    • The energy is captured through heliostats, giant mirrors that follow the path of the sun with two-axis movement. These are aimed at the receiver located at the top of the tower.
    • Absorption of radiation by heating a stream of cold molten salts to a temperature of 565°C / 1049ºF
    • Storage of hot salts in a tank system.
    • Extraction of hot salts from tanks to transfer heat to water and thus create steam.
    • Generation of electrical energy by means of a steam turbine.

    Concentrated Solar Power

    The heat storage system consists of cold and hot salt tanks which facilitate the production of energy day and night.
