TransnetBW GmbH operates the electricity transmission grid in Baden-Württemberg. In doing so, we secure the electricity supply in the region, Germany and Europe. Our clients and partners include many electricity traders, power plant and distribution system operators in Germany and abroad.

Some 80 transformers connect our transmission grid to the distribution grids in Baden-Württemberg. Via these access points, we supply electricity to internationally renowned industrial enterprises and more than 11 million people in Baden-Württemberg – reliably and at every hour of the day. In this way, TransnetBW ensures the economic strength and quality of life in south-west Germany.

In addition, our grid carries a large proportion of the electricity consumed in Germany and throughout Europe. Thirty-five interconnection points integrate the TransnetBW grid into the national and European grids. Together with our neighbouring network partners in Germany, France, Austria and Switzerland, we also make available the transmission capacities required for cross-border electricity transmission, equitably and without discrimination.

The departments at TransnetBW involved in this project are the Strategic Asset Management, Asset Technology and System Behaviour and the System Operation.

The Strategic Asset Management has deep insight into the energy system of the future and its interdependencies. Leveraging this expertise, it plans the demand-based electricity grid – internationally, nationally, and regionally.

The department Asset Technology und System Behaviour identifies and analyses asset technologies and their impact on the network. For this purpose, it develops assessment methodologies and deploys grid data and models.

The System Operation is responsible, among other tasks, for ensuring grid security and maintaining the balance between generation and consumption in the control area. It coordinates the system operation with TSOs, connected DSOs, power plants and balancing groups and collaborates with national and international neighbors as well as the regional coordination centers TSCNet and CORESO.
