Resumen del contexto y de los objetivos generales del proyecto

The concentrated solar thermal accumulation in CSP makes it one of the most promising renewable alternatives to facilitate the management of the energy mix. The main application of CSP is the production of electricity, but its applications are wider and include, depending on the configuration, since heat input systems for desalination and industrial steam generation to photochemical reactors.
Among the possible actions to reduce the cost of energy production are reductions in CAPEX and OPEX of the solar field and, in turn, improving plant performance. About the 40% of the overall costs of a central tower solar plant corresponds to the solar field, which demonstrates the need to improve the relation between quality-cost from the heliostats. So that, this is the area in which cost reductions will lead to a bigger impact in reducing the cost of energy.
However, for this to become a reality, it is imperative that the solar field is as efficient as possible in both performance and cost, as well as the interrelationships of the pair solar field - receiver are optimized.

Trabajo realizado desde el comienzo del proyecto hasta el final del período abarcado por el informe y los principales resultados hasta la fecha

Tewer has proven that the existing solar fields and its performance are not properly optimised and, therefore, this is an important way to reduce the LCOE of tower technology solar plants..

Avances que van más allá del estado de la técnica e impacto potencial esperado (incluida la repercusión socioeconómica y las implicaciones sociales más amplias del proyecto hasta la fecha)

Tewer proposes a solution that will mean a spearhead in solar field optimisation, thus optimizing the costs of the solar field, making the technology more competitive. This proposal results in an effective optimisation of solar fields in such a way that the impact in the production and cost of the solar plant is positive and these changes lead to a competitiveness improvement.
