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.
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;
- the molten salt solar receiver, 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;
- the heliostat designed and patented by SENER.;
- 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.
Thermal storage technology
The molten salt thermal energy storage system can be incorporated in both parabolic trough collector technology and in central tower configuration. Incorporating storage into solar-powered thermal plants makes it possible to keep operating even in the absence of solar radiation (at night time or in passing cloudy weather). Thanks to this storage capacity, a clean energy source such as solar power can be rendered manageable and stable in order to supply electricity to the network based on demand.
Parabolic trough technology
Parabolic 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.
Since 2007, SENER has implemented 27 parabolic trough power plants all across the world and has developed its own system of collectors: the SENERtrough® system. More than 2500 km of collectors have been built by SENER and are working at 100% of their capacity.
