As a direct successor of NSR Interreg IIIBs POWER project, it is centred on the development of a strong Offshore Wind Industry (OWI) cluster in the NSR. Core activities include a strengthened stakeholder and business-to-business network, leading to knowledge transfer and bringing together complementary expertise to create more innovation in the sector, energy grid reinforcement across the NSR, developed skills training courses (including higher education and addressing unemployment) to create benefits for restructuring regions, and raise acceptance among the wider public as a basis for wider roll-out of wind energy installations. Achievements: • Within the POWER cluster project the exhibition Fascination Offshore was organized to raise the awareness for offshore wind energy among a wide public audience,• Two major studies were conducted within the framework of the project which a) compiled experiences, challenges and recommendations with regard to the Offshore Wind Energy sector in the NSR (State of the Offshore Wind Industry in Northern Europe – Lessons learnt in the First Decade - Ecofys study) and b) presented relevant lessons to be learnt from the oil and gas industry (Overcoming Challenges for the Offshore Wind Industry and Learning from the Oil and Gas Industry),• Innovative databases were developed for raising social acceptance and providing information about the capabilities of companies related to the OWE: Web-based OWF site selection tool (WebSDSS training tool) / Interactive OWE cluster map for the NSR (POWER cluster Mapergy),• A series of OWE communities events and Business-to-Business network events were organized to arrange new business contacts and contracts (e.g. German mayors conference; Offshore Renewable Energies – regional partnership roundtable event and workshop),• Due to the participation of different educational institutions, POWER cluster contributed to skills development for people in charge of the OWE sector (e.g. Compendium in Maintenance),• With regard to the organization of the mid-term and the final conference, POWER cluster provided a platform for transnational knowledge exchange and networking as well as the dissemination of actual data and experiences regarding the OWE branch.
