The visit, composed by twelve clusters belonging to different European countries: Germany, Bulgaria, Poland, Czech Republic, France and several regions of Spain (Catalonia, Aragon and the Canary Islands), aimed to offer attendees – all of them cluster managers – a global vision about the ecosystem of clusters in Catalonia and Spain, and foster the exchange of good practices. It should be noted that the members of the INNODROP project were invited to join the CLUSGRID consortium to increase the impact of the study. During the visit, the members of the consortium had the opportunity to learn about Clusters policy in Catalonia from Emma Vendrell, of ACCIÓ, to study first-hand several clusters of very different typology, both by topics, by origin and by structure. As well as this, the group had the chance to learn in depth about Solartys and its ecosystem of clusters. Mr. Jordi Giral from CITCEA – Polytechnic University of Catalonia gave an overview on the Smart Grid sector. Study visit was also an excellent possibility to discuss the outcomes of the two case studies elaborated after the on-line training.
