The poster aims to present the European DERri Project and the up to now achieved results. DERri – Distributed Energy Resources research infrastructure – is an European funded project (Nr. 228449) coordinated by Ricerca sul Sistema Energetico RSE S.p.A., under the FP7 Research Framework Programme. 15 partners from 12 countries distributed all over Europe cooperate in the project. All partners have leading DER expertise as well as exceptional and supplementary DER research infrastructures and facilities. In addition to internal Networking Activities and Joint Research Activities, DERri provides European researchers the opportunity for free of charge transnational access to the DERri Research infrastructures. The consortium includes all the members of the Network of Excellence DERlab, with the addition of four more partners, making up an important group providing DER research infrastructures and leading DER expertise. The first research activities using the integrated structures will be described, together with the results obtained by the whole consortium in terms of improving standardisation and common approach. The Joint Research Activities (JRAs) have the double aim of improving the access of users to the research facilities, but also of developing further synergies and complementary capabilities between the partners. They will be also detailed, showing objectives, overall design and results.
