Energy systems with high shares of variable renewable power generation have an increased need for power system flexibility. In parallel, renewable energy has an important role in circular economy as circular activities such as material processing consumes power and heat. This paper examines if harnessing flexibility from circular economy processes related to upgrading of side and waste material flows increase the value of a renewable energy system. Analysis is conducted on a selected case region as the availability of both circular processes and renewable energies are region-specific depending of the local characteristics. The potential of circular economy as a demand source for abundant variable renewable energy supply is compared to a highly electrified transportation sector and to power-to-heat conversion in addition to the baseline scenario. The analysis is performed with a developed mixed integer linear programming (MILP) model in which energy system operation and selected circular material flows are simultaneously optimized.
