Grid issues are considered a major barrier for higher penetration of intermittent energy sources especially in remote or outlying regions, including islands. STORIES action aims to increase RES-E penetration in islands, through the promotion of hybrid system of RES-storage technologies. STORIES will systematically analyse the economical conditions, market organisation, regulatory framework and existing barriers faced by these systems. STORIES aims to develop in close cooperation with policy-makers, regulators and industry a roadmap for the introduction of hybrid RES/storage systems in European islands. Ultimately, the effective involvement of the key target groups throughout the project, including local authorities, would result in an increased penetration of these systems in islands.
