The use of renewable energy sources is a major strategy to mitigate climate change. Yet Sinn (2017) argues that excessive electrical storage requirements limit the further expansion of variable wind and solar energy. We question, and alter, strong implicit assumptions of Sinn’s approach and...

Die Umsetzung der Energiewende erfordert einen weiteren starken Ausbau der erneuerbaren Energien in Deutschland. Jedoch werden in der energiepolitischen Debatte immer wieder Zweifel geäußert, ob eine weitgehend auf fluktuierender Wind- und Solarenergie basierende Energieversorgung möglich...

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...

Starting from a low level, in recent years the battery-supported self-consumption of solar electricity (solar prosumage) has grown significantly in Germany. Its growth is primarily due to the opposing trends in household electricity prices and feed-in tariffs in conjunction with government...

We develop a dispatch and investment model to study the role of power storage and other flexibility options in a greenfield setting with high shares of renewables. The model captures multiple system values of power storage related to arbitrage, dispatchable capacity, and reserves. In a baseline...

The German energy transition makes it necessary to increase flexibility in the electricity system. Different forms of power storage may play a part in this, yet there is competition with other options on the production or demand side. In the short term, the further expansion of electricity...

Die Energiewende erfordert eine höhere Flexibilität im Stromsystem. Unterschiedliche Arten von Stromspeichern können hierzu beitragen, wobei sie in Konkurrenz zu anderen erzeugungs- und nachfrageseitigen Optionen stehen. Kurzfristig ist der weitere Ausbau der Stromerzeugung aus volatilen...

DSM (demand-side management) merits increased attention by power system modelers. Numerical models should incorporate DSM constraints in a complete and consistent way. Otherwise, flawed DSM patterns and distorted conclusions on the system benefits of demand-side management are inevitable....

Using electricity for heating can contribute to decarbonization and provide flexibility to integrate variable renewable energy. We analyze the case of electric storage heaters in German 2030 scenarios with an open-source electricity sector model. Making customary night-time storage heaters...

A flexible coupling of power and heat sectors can contribute to both renewable energy integration and decarbonization. We present a literature review of model-based analyses in this field, focusing on residential heating. We compare geographical and temporal research scopes and identify...
