Dataset for TradeRES scenarios The TradeRES project created four central scenarios of the future European power system. “Scenario” within TradeRES refers to a structured input data collection that encapsulates certain properties of the underlying future energy system. The four scenarios, abbreviated S1, S2, S3 and S4, are carbon-free by assumption and vary in terms of the flexibility of the demand-side, the variability of the supply-side and the degree of sector-coupling. In addition, TradeRES created a scenario S0 to represent an intermediate energy system on the path to decarbonisation. This scenario S0 with a 60% non-thermal renewables penetration, is considered in some case studies as a departing scenario for reference. It considers exogenous electricity generation capacities based on 2030 national energy and climate plans. In addition, TradeRES created scenarios for additional analysis where, for example, the weighted average cost of capital (WACC) or investment of technologies, the hydrogen import price or the weather year were varied. Furthermore, this database includes .sqlite-databases that correspond to publications based on applications of this database to the energy system model, whose repository is linked below. To access the complete dataset, all versions of this repository have to be used. The common data on the scenarios are given in the supplementary data file D2.1_TradeRES_Scenario_data_v3.xlsx. The table below describes the data items that are included in the data file. The report D2.1_TradeRES_A-database-of-TradeRES-scenarios_Ed3.pdf describes in more detail the scenarios and data files.
