SENER is world leader in thermosolar power based on number of projects carried out as well as technological ability and innovation. It has completed over 29 plants spread throughout Spain, South Africa, Morocco, and the United States, totaling over 2,000 MWe of installed capacity and saving over a million tons of CO2 per year. Among them, SENER is part of the EPC building consortium of the Solar Complex NOORo, in Ouarzazate - Morocco, the largest on the planet. SENER carries out the three phases of the solar thermal project NOORo (NOORo I, NOORo NOORo II and III).

SENER's history in solar power goes back to the 1980s, giving it a considerable technological advantage over its competitors. It has started up pioneering plants such as Andasol, the first thermosolar plant to incorporate a molten salt heat storage system, and Gemasolar, the world’s first commercially operating central tower receiver plant with this same molten salt system and the first to produce electricity for 24 hours continuously using just solar power. 

Planta termosolar NOORo I en Ouarzazate (Marruecos)As a result of this long history, SENER has been able to develop the most advanced technologies:

  • heat storage, which allows plants to continue producing power in the absence of solar radiation;
  • increased thermoelectric efficiency, with the development of central tower with molten salt receiver technology;
  • SENSOL electricity production simulation and projection software;
  • the SENERtrough®  parabolic trough and its second version, SENERtrough®-2;
  • heliostat actuators;
  • heliostat control system. 

SENER contributes with its experience in solar plants, both in parabolic trough configuration and in central tower with heliostat field configuration. Both technologies can incorporate a molten salt heat storage system, which makes it possible to continue operating in the absence of solar radiation (at night or during cloudy weather). Thanks to this storage capacity, a clean source of energy such as solar energy can become manageable, and capable of responding to the grid’s demand.

Parabolic trough technology

Captadores cilindroparabólicos SENERTrough en las plantas Valle 1 y Valle 2Parabolic trough technology consists of a series of parabolic mirrors arranged in horizontal rows that concentrate solar radiation in a central tube containing thermal oil. The hot oil is used to vaporize water, which, channeled to a steam turbine, drives a generator that injects electrical energy into the grid. Likewise, the excess power is used to heat molten salts and thus store the heat to continue to produce electricity at times of low solar radiation or at night.

SENER has completed 28 projects for plants of this kind and has developed its own trough system, SENERtrough®.

Central tower technology

Planta termosolar GemasolarSENER designed and built through to its start-up Gemasolar, the first utility scale power plant based on concentrated solar energy with central tower receiver technology and a molten salt storage system.

Thanks to its configuration, Gemasolar can continue to produce electricity for 15 hours without any sun, and therefore it is significantly more efficient than other thermosolar plants that are currently in commercial operation.

After the success of the Gemasolar plant, SENER has taken on the new challenge of designing and building the next generation of central tower plants, with 150 MWe capacity.
