This module covers the regulatory side of energy grids. It is structured along the multi-layered regulatory sphere of the energy sector. After a theoretical introduction into the theory and instruments of regulation, it starts on the European level, dealing with EU Energy policy and regulation. It follows the national level, looking into the national transposition of EU regulatory law and the practical regulation on national level. It then goes on, focusing on the regulation management on business level. Students will be able to critically reflect on the current theory and practice of regulation in Germany and Europe in both the electricity and gas sectors, to assess the significance and effects of regulation on the energy system on the one hand and on companies on the other, and to present options for optimizing regulation management.
