The transformation of Europe’s energy system creates both challenges and opportunities for the hydropower sector. Hydropower needs to seek out value within the electricity market aligned with other sources of renewable and sustainable energy, whilst operating and building plants in environmentally sensitive and acceptable ways. The call H2020 LC-SC3-CC-4-2018: “Support to sectorial fora”, item 2: “bringing together stakeholders of the hydropower sector in a forum” provides a unique opportunity to bring together the hydropower community and to develop a Research and Innovation Agenda, and a Technology Roadmap mapping implementation of that agenda. These will support implementation of research and innovation for new hydropower technologies and innovative mitigation measures. The HYDROPOWER-EUROPE project delivers these objectives through an extensive programme of stakeholder consultation. The consortium brings together six different associations and networks spanning the whole research and industry value chain. These networks, along with representatives of civil society and European and national authorities, will form the initial stakeholder consultation base. Through an extensive, cyclic programme of consultation – both online and through various regional, European and International workshops – research needs and priorities will be established supporting development of the Hydropower Research and Innovation Agenda. The consultation process also facilitates discussion around issues and perceptions affecting the implementation of hydropower in Europe. Conclusions from this will underpin development of the Technology Roadmap, addressing any issues affecting uptake of the research and innovation agenda. Finally, the HYDROPOWER-EUROPE project will also consider ways in which the forum, established through this initiative, may become sustainable beyond the 3-year project programme, so supporting uptake and implementation of the research and innovation agenda.
