In most European countries, taxes and levies, the state-induced components of electricity prices, constitute the major share of electricity prices for consumers and are charged at a fixed rate. This study analyzes whether switching stateinduced price components to time varying rates can support the integration of variable renewables (VRE) and, thus, help to efficiently achieve the overarching goal of decarbonizing the energy system. Based on game theory and linear programming, we introduce a novel simulation model of the power market. For a quantitative case study, the model is parametrized to represent a German energy system that meets the political objective to increase the share of renewables (RE) in power generation to 80% in 2050. We find that dynamization supports the integration of VRE into the energy system. Whether dynamization is an efficient instrument to promote decarbonization as well is highly dependent on the policy framework in place.
