Right here, right now? The role of spatio-temporal minimum renewable shares for energy system transformation pathways
Energy system optimization models are important tools to provide insights
regarding trade-offs and interrelations in cost-efficient transformation
pathways towards a climate neutral energy system. Using an optimization model
of the European electricity system, we study the influence of either an
emission cap or temporally resolved minimum renewable generation shares as
means to power system decarbonization. Such minimum shares serve as a stylized
representation of novel, more granular procurement or certification schemes for
renewable power generation. We observe that decarbonization through minimum
shares results in a significant increase in system costs compared to the least
cost solution obtained through a direct implementation of the corresponding
emission reduction as a cap. Nevertheless, these shares provide direct
incentives for expanding renewable generation and storage technologies, thus
acting as an additional, potentially more robust decarbonization mechanism
