Potential for greater flexibility by linking the electricity, heating and cooling sectors



The purchase of electricity and heat in industry as well as in the commercial, trade and service sector causes around a third of greenhouse gas emissions in Germany. The goal of reducing greenhouse gas emissions requires extensive measures to increase efficiency, save energy and to expand renewable energy generation. The increasing proportion of fluctuating generation from renewable energies must be met with the targeted use and management of flexibilities in the energy system.

FlexGeber will show through three case studies how the electricity, heating and cooling sectors can be linked and how this can create potential for greater flexibility. The project will develop market and operator models that address the connectors between the sectors and enable the integration of tertiary and industrial companies into the energy industry. The flexibility options identified for the building sector are integrated into a regional and Germany-wide energy system and energy market model in order to evaluate their interaction with the energy system and the associated effects. IKEM supports the project with analyzes on the legal framework.
