Abstract: Energy storage is an important option to enable a higher share of variable renewable electricity such as wind and solar, in the energy system. Pumped hydropower storage (PHS) is currently the only storage technology able to provide the large storage needed for accommodating renewable electricity under the 2020 EU energy targets. Moreover, the transformation of an existing water reservoir into a PHS facility has a much smaller environmental and social impact compared with most new hydropower plant in Europe. The JRC collaborated with University College Cork (UCC) in Ireland to develop a GIS-based methodology and model to assess the potential for transforming single reservoirs into PHS systems. Then the JRC organised a multi-disciplinary expert workshop to validate the methodology and model, provide a set of recommendations for the improvement of the effectiveness and efficiency of the methodology, address the issue of data availability in the Member States, and share and disseminate the methodology among relevant stakeholders, such as policy makers, industry, research, etc. This report presents the results of the workshop which concluded that the assessment of the potential for PHS is different when its purpose is site assessment or policy planning and decision-making; and that the use of geographical information systems models is effective, efficient and convenient for both purposes whereas what differs is the intensity of the use of the tools, the detail of the data needed and the assumptions behind the model and methodology. The restriction to PHS development imposed by the different types of nature protection areas (NPA) is different in different countries. Also, laws and perceptions change with time and as PHS projects take a long time to realise the scientific assessment of European or national potential cannot take current NPAs and laws into account with the same weight as the site assessment for a proposed PHS project. Country and European assessment is heavily dependent on the assumptions taken. For example, sensibility analysis showed that enlarging the maximum distance between two reservoirs from 5 to 20 km increased the theoretical potential for Croatia from 60 GWh to nearly 600 GWh.
