Summary of services to the CSP industry

Since its inception, the Solar Thermal Energy Department of CENER has dedicated a large part of its activities to support the solar thermal power industry in Spain and worldwide. These activities can be classified into three groups: Technical assistance: Technical assistance and advice to companies to ensure the

success of commercial solar power plants projects. R&D Projects: Collaborations with companies in defining and developing R&D j p g p g

projects for development and improvement of solar thermal power technologies. Strategic Assessments: Strategic advice to institutions and companies in relation to

technology and solar thermal power industry.
