As part of the rapid transformation of European power generation from a system dominated by fossil generation to a largely decarbonized system necessary to reduce greenhouse gas emissions, combined heat and power (CHP) is a fundamental pillar of future system design. These flexible, highly efficient plants, which can be designed in a decentralized manner, serve as a bridge between the electricity and heat sectors and can achieve particularly high efficiencies through the parallel generation of electricity and thermal energy for district heating and process heat. In the future scenarios for a low-emission German power generation, CHP generation therefore plays an important role and an increasing relevance of flexible generation from CHP plants in an energy system characterized by the volatile energy sources wind and solar is to be expected.

Contents of the work

The aim of this thesis is to investigate the influence of CHP plants and their restrictions due to the necessary heat supply on the electricity market. For this purpose, an overview of the technological and economic fundamentals of CHP generation in Germany shall be gained at the beginning with the help of a literature research. With this knowledge, an integration of CHP plants into a market simulation of the electricity market will be carried out, which will allow a model-based investigation of the question. For this purpose, first a model for the determination of regional heat demand will be created using meteorological data, which will provide the basis for the deployment restrictions. In a second step, these constraints will be integrated as technical boundary conditions into an existing market simulation model and the resulting influences on different scenarios of the future energy system will be investigated.


  • Basic knowledge of energy economics and interest in questions concerning the German and European energy transition
  • Previous knowledge in optimization and/or modeling is advantageous, but not necessary
