Abstract

Present energy system models are mainly based on techno-economic input parameters whereas social or political factors are neglected. This paper presents an approach to include social acceptance in energy system modelling, focusing on electricity transmission grid expansion projects in Germany. Qualitative as well as quantitative research techniques were applied: An analysis to quantify social acceptance was developed and implemented for 19 German districts (Landkreise) and acceptance-based delay assumptions for all German districts were derived. The dimension of social acceptance was integrated through years of delay. On the basis of assumed delays, different electricity grid expansion scenarios could be created. The results show that low delays can only be expected in regard to a few projects in Schleswig-Holstein. Moreover, the findings emphasize the importance of a commitment to grid expansion projects on the part of regional governments.
