    Title: Profitability of Photovoltaic-Battery Systems for Private Households

    Abstract: During my stay at the Information Systems and Science for Energy (ISS4E) Laboratory (Prof. Keshav/Rosenberg) I was involved in research on the profitability of photovoltaic-battery-systems for private households in different jurisdictions. Whereas in Germany these systems are already economically applied, their market penetration in other countries is highly uncertain. This is mainly evoked by the high German electricity tariffs (about 30 euro-ct/kWh). If, however, these systems will successfully penetrate the market, the energy system will face a game changer: The load patterns will become very flexible. Fiodar Kazhamiaka, Srinivasan Keshav, Catherine Rosenberg and I extended an existing mixed integer model. The main improvements focused on the economic part, the consideration of battery degradation and electric vehicle charging. Additionally, we discussed the applicability of these systems in developing countries with grid outages.

    Biography: Dr. Patrick Jochem (Karlsruhe Institute of Technology, KIT) is head of the interdisciplinary research group “Transport and Energy”. He studied Economics at the universities of Bayreuth, Mannheim and Heidelberg, Germany. In 2009 he finalized his PhD at KIT in Transport Economics on greenhouse gas mitigation in road transport, which was funded by the German Federal Environmental Foundation (DBU). Since 2012 he holds additionally a post-doc position at the Karlsruhe Service Research Institute (KSRI) at the KIT. In 2014, he was awarded by the Heidelberg Academy of Sciences and Humanities. He is involved in several research projects in the field of electric mobility and he has published over 100 research papers in peer-reviewed international journals and conference proceedings. He is guest Editor of the Elsevier Journal “Transport Research Part D: Transport and the Environment”. His research focus is on market penetration methods, energy system analysis, and environmental research.
