REELCOOP stands for REnewable ELectricity COOPeration, and will address 5 areas: photovoltaics (PV), concentrated solar power (CSP), solar thermal (ST), bioenergy and grid integration. REELCOOP will develop decentralised (distributed) building integrated PV systems and ST/biomass micro-cogeneration systems, as well as centralised generation of electricity in hybrid solar/biomass power plants. This is in accordance with the EU SET-Plan approach of developing a European electricity grid able to integrate renewable and decentralised energy sources.The overall aim of REELCOOP will be to significantly enhance research cooperation and knowledge creation on renewable electricity generation, involving Mediterranean partner countries (MPC), while at the same time developing and testing new renewable electricity generation systems. The proposed systems will be developed in European organisations with collaboration of MPC partners, and tested under real-life operating conditions in the MENA region, thus establishing a cooperation network amongst partner countries.Three novel prototype systems will be developed and tested, being representative of both micro (distributed) and large (centralised) scale approaches to electricity generation: prototypes 1 and 2 are representative of typical micro-generation systems, while prototype 3 is representative of a large scale power plant on a reduced scale. The development of the 3 prototypes will also contribute to bring to the market energy efficient, renewable electricity generation systems. The environmental sustainability and economics of the prototype systems will be assessed, and the results obtained will be disseminated to industry and research, as proof-of-concept of renewable electricity generation solutions. Grid integration will also be assessed. The prototype systems will have a great potential for exploitation/commercialization. The commercialisation of the systems will bring economic and environmental benefits to the EU.
