In its strategic ‘energy concept’, the German government has set goals for the structure Graphic: Question, illustrated schematically. Source: Scholz, Y., DLR 2012of the German power supply system until the year 2050. These goals include the phase out of nuclear energy use until 2022 and a share of renewable energy of 80 % in the year 2050. In this project, the effects of different developments of the power sector in otherEU countries on the German power market are assessed in terms of power and money flows. In order to do so, existing energy sector scenarios that are assumed to represent the range of possible future developments are selected. An energy system model is adapted to model the operation of power plants, storage units and transmission lines in Germany and Europe. The modeling effort is supposed to enable concluding on the marginal costs of power generation in the course of a whole year in sufficient detail. The correlation between marginal costs and wholesale prices for electric power are investigated using structural econometric models, possibly with data on RE-feed-in and utilization of interconnector capacities. The results are used for the validation of the modeling results and to draw general conclusions on the formation of prices at the German power market. The results are also used for an outlook on the future development of price formation in a changed power system
