Dr.-Ing. Dipl.-Wirt.Ing. Thiemo Pesch

Dr.-Ing. Dipl.-Wirt.Ing. Thiemo Pesch studied Electrical Engineering and Information Technology with a focus on Electrical Power Engineering at RWTH Aachen University and Chalmers University of Technology, Gothenburg, Sweden. In addition, he completed the diploma programme Management, Business and Economics at RWTH Aachen University. Afterwards, he wrote his doctoral thesis, supervised at RWTH Aachen University, on the subject of “Multiscale Modelling of Integrated Energy and Electricity Systems” at the Institute of Energy and Climate Research – Systems Analysis and Technology Evaluation (IEK-STE) at Forschungszentrum Jülich. The focus of the work was on the development of high-resolution models for the European electricity market and the German transmission grid as well as their coupling with a holistic energy system model. During this time, he already managed various third party projects. Since 2019, he has been working at the Institute for Energy and Climate Research – Energy Systems Engineering (ICE-1) of Forschungszentrum Jülich, where he is the head of the Energy Grids department since end of 2020. Since 2022, he is also head of the High Performance Computing department.
