Ein zukunftsfähiges Strommarktdesign für Deutschland

The Federal Republic of Germany is pursuing the goal of achieving climate neutrality within the next 20 years. This requires the complete decarbonization of the electricity sector. For this, fossil-fuel power generators are to be completely eliminated from the market and replaced by renewable energies. To make this possible, an electricity market design is required that establishes the necessary framework. This study provides a comprehensive overview of the challenges and solution options that arise for today's electricity market design in the course of the transformation to an electricity system with 100% renewable energies in Germany. Various methodologies were applied for this purpose, with a focus on in-depth literature research. A comprehensive analysis of the entire market was created from previous academic studies, which mostly focus on individual aspects of electricity market design. The results provide a classification of various discussed solution instruments based on their advantages and disadvantages. Furthermore, the results provide information on the urgency of the various challenges and show the extent to which they are addressed by the considered solution options. Particularly in the area of ​​long-term refinancing of renewable energies, it became clear that there are significant uncertainties, which are primarily due to the uncertainty regarding the development of hydrogen prices. Urgent action is needed here.
