Abstract:
Das Erneuerbare-Energien-Gesetz wird zurzeit heftig diskutiert. Es hat zwar eine stark zunehmende Stromerzeugung aus erneuerbaren Energiequellen ermöglicht, wird aber mit Strompreiserhöhungen und Ineffizienzen in Verbindung gebracht. Die Autoren fordern eine grundsätzliche Anpassung der Energiemarktordnung.
Abstract (Translated):
The German electricity market is changing fundamentally as renewable energy replaces conventional sources. Simultaneously, regional imbalances between generation and consumption are appearing. The authors sketch a new market design for the German electricity market, jointly taking into account the efficient expansion of renewables and the grid's stability. A premium paid in addition to the spot market price promotes renewable electricity. Furthermore, they propose to split the German electricity market into a small number of price zones to cope with insuffi cient transmission capacities. By systematically strengthening regional and temporal price signals, the authors expect a notable cost reduction of the energy transition to be achieved.
