The energy transition requires a broad and transparent discussion on how quickly and at what cost the 1001TP3 supply of renewable energies should be achieved. The choice of expansion concepts for the generation, transport and storage of energy depends on this, which will have a significant impact on the costs and duration of the energy transition from a technological and economic perspective. The acceptance of the population affected by the construction measures can have a cost-reducing and accelerating effect in the positive case, but can also have a cost-driving and delaying effect in the negative case. The overall aim of the project was to use a simulation and optimisation model to depict the complex interplay of technological-economic, socio-ecological and political-legal conditions of the electricity supply and, on this basis, to model development paths for a 100% renewable electricity supply. The aim of the project was to integrate social-ecological key factors and success factors of participation into the previously purely technical-economically orientated electricity market model "renpass" of the University of Flensburg. This in turn was to enable the presentation of differentiated development options for the energy transition using the example of individual hotspot regions for a 100 % renewable electricity supply in 2050. This methodological development was carried out in close cooperation with practice partners and a scientific project advisory board.
