Description of the project

Electric storage systems are a key technology for a decentralized energy supply and hence for the transition to renewable energy. In medium-sized enterprises, an important sector in the German economy, electric storage systems are installed rarely. The project DABESI (»Datengetriebene Auslegung und Betriebsführung von dezentralen Elektrischen Speichern in produzierenden mittelständischen Industriebetrieben«) aims for an econimical optimization of the electric consumption in medium-sized enterprises by the use of electric storage systems.


To this goal five steps are panned:

  • Analysis of higly resoluted load data to identify the potential for electric storage systems as well as systematic inefficiencies

  • Development of a generic model for the optimal sizing and selection of storage technology under consideration of economical and company-specific conditions

  • Conception of versatile operation control strategies for electric storage systems with the help of self-learning algorithms if applicable

  • Development of a system architecture which allows to scale and combine storage technologies freely and the exchange of storage systems

  • Sizing, installation and testing of storage systems in selected enterprises
