Cross-modal utilization potential of generation and storage capacities for grid services

In this research project, scientists of the Reiner Lemoine Institute investigate how energy generation and storage facilities as well as flexible consumers of the rail, road and waterway modes of transport can be used to provide grid services and thus support safe, efficient and economical grid operation.

Energy resources can stabilize the power grid

Due to the increased use of volatile renewable energy sources and the electrification of other sectors, the electricity grid is facing major challenges. The existing power grid must be used efficiently, generation and consumption must always be balanced and the stability and quality of the power supply must be guaranteed at all times. To make this possible, the flexibility of energy generation plants, storage facilities and consumers can be used to provide grid services.

Focus on energy generation systems and storage facilities

The focus of the investigation is on energy systems of the transport carriers, such as photovoltaic and wind power plants, wind turbines, charging infrastructure, battery storage, pumping stations and electrolysis plants. As part of the project, the project team is developing the technical, economic and legal framework conditions under which the systems can provide grid services. In addition, the scientists will select model regions in coordination with the Federal Railway Authority, in which they will carry out a detailed inventory of the energy systems and storage capacities and quantify the potential for the provision of grid services. For this purpose, various sources are evaluated and compiled and interviews are conducted with experts.

Recommendations for action to exploit the potential

Using the research results, the RLI scientists are working with the project partner IKEM to develop specific recommendations for the provision of grid services in the transport sector. These include recommendations for legislative amendments, technical guidelines and a presentation of the economic potential.
