The proposed research project aims at investigating market integration in European electricity markets with a focus on Switzerland. We identify current market integration empirically based on econometric models. This requires the development of a structural multi-country system model that takes into account unilateral policy decisions and recent developments in market integration such as market coupling. In addition we will provide simulation studies to analyze companies’ future price setting and dispatch decisions contingent on Swiss policy making. Thereby we can analyze welfare optimality of Swiss policy options including renewable expansion, conventional and nuclear capacity targets, interconnector extension, energy efficiency policies as well as different antitrust policy options.The final report is available for download on the project page of Aramis.
