We analyze the interactions between different renewable support schemes and the benefits of real-time pricing (RTP) using a stylized economic model with a detailed demand-side representation calibrated to the German market. We find that there are considerable differences between a market premium...

I examine the effects of increasing amounts of fluctuating renewable energy on residual load, which is defined as the difference between actual power demand and the feed-in of non-dispatchable and inflexible generators. I draw on policy-relevant scenarios for Germany and make use of extensive...

We examine the effects of future renewable expansion in Germany on residual load and renewable surplus generation for policy-relevant scenarios for 2022, 2032 and 2050. We also determine the storage capacities required for taking up renewable surpluses for varying levels of accepted curtailment....

Recent developments in electricity markets such as the increased deployment of variable renewable generation have prompted renewed interest over the role of energy storage. While storage technologies can in principle provide various benefits for the functioning of an electrical grid, many energy...

Achieving the objectives of the German governments 2010 Energy Concept and the accelerated phase-out of nuclear energy will require significant investment in restructuring energy supply. In particular, this includes investment in installations for the use of renewable energy sources in the power...

We examine the role of prosumage of solar electricity, i.e. PV self-generation combined with distributed storage, in the context of the low-carbon energy transformation. First, we devise a qualitative account of arguments in favor of and against prosumage. Second, we give an overview of...

Die Energiepolitik steht vor zwei großen Herausforderungen: Erstens wird fossile Energie in Zukunft immer knapper und teurer, und weltweite Konflikte um Rohstoffe werden weiter zunehmen. Zweitens führt die Verbrennung fossiler Energieträger, insbesondere von Kohle, zu einem Anstieg der...

Ausgehend von einem niedrigen Niveau ist die Eigenstromversorgung mit Solarenergie und Batteriespeichern in Deutschland in den letzten Jahren deutlich gewachsen. Diese Entwicklung ging insbesondere auf den gegenläufigen Trend von Haushaltsstrompreisen und Einspeisetarifen sowie eine staatliche...
