ElMaR (Electricity Market Design and Renewables) lays the modelling foundations to be able to address key questions concerning the shift in energy generation towards more renewable energy sources. ElMaR offers an innovative energy-economy model framework, which combines and links state of the art large-scale bottom-up partial equilibrium electricity market model with top-down general equilibrium model in a multi-regional setting. The bottom-up partial equilibrium electricity market model features a detailed engi-neering representation of power generation and dispatch over a representative year. It accounts for phys-ical restrictions of the Swiss power network. For each individual hour, electricity demand, supply, dispatch and transmission can be displayed in high regional resolution. The top-down general equilibrium captures economic transactions amongst firms (industries) and households. The regional disaggregation (18 re-gions / cantons) allows the analysis of regional distribution effects of policy measures. In order to use ElMaR for the evaluation of the impact of policy measures, the parametrization of the model would have to be further refined and complemented.
