While there are several research projects on the Hungarian renewables market, until now only partial aspects of the RES-related trade-offs of the Hungarian energy market have been recognized. Due to the size and the diversity of the industry, the research has focused on one particular problem set (e.g., technology, value chain, strategy, regulatory) and only has a glimpse of some of the trade-offs. To develop the comprehensive list of the relevant RES trade-offs in Hungary we aimed to reach a common understanding across the industry actors. Hence, we used concept mapping as a mixed method and relied on the inputs of 42 respondents, who were stakeholders in the energy value chains. In the iterative process, 40 statements became part of the ‘reduced list of statements’ that consisted of the actions and the trade-offs. The statements were then evaluated by the participants. With hierarchical cluster analysis the five-cluster solution was identified as the best fit and then their labeling was discussed by the respondents. The 5 labeled and ranked clusters were: 1) Low level strategy (regulations, pricing, complexity management) (3,35/5) 2) High-level strategy (regulatory, tariff system, cooperations) (3,29/5) 3) Infrastructure development (technology, PR) (3,19/5) 4) Network optimization (network operation, resource management) (3,11/5) 5) Social aspects (stakeholder impact) (2,20/5) The linear correlation coefficients between the various subgroups were very high. Comparisons were made of industry experience (‘Juniors’, 'Mid-level', ‘Seniors’), type of affiliation (‘State controlled’, ‘Not state controlled’) and qualification (‘Economics and Management’, ‘JD’). Overall the respondent group had a strong agreement on the importance of the factors with a same trend in all cases. With the ladder graphs in almost all cases some potential disagreements could be identified. The suggested utilization of the results: 1) Inputs for relevant stakeholders to prioritize between RES technologies (e.g., National Energy Strategy). ...
