The objective of this report is twofold. On one hand, to review the current cooperative initiatives that have been launched over the past years in the European Union, study their characteristics and achievements and outline the lessons learned. On the other hand, to assess competitive dispatchable RES technologies that could be utilised for achieving high RES penetration scenarios, especially if the long-term European decarbonisation strategy for 2050 is considered. To this end, three technological options are studied: CSP with storage, PV with storage and offshore wind with storage. According to the report’s results, CSP with storage seems a competitive option against the other two technologies, considering the provision of ancillary services and for storage capacity over 4 hours.
