About Transnet BW

Guaranteeing economic strength and quality of life

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.

About Transnet BW

A young company with solid roots

TransnetBW GmbH was launched in March 2012 when the former EnBW Transportnetze AG – itself founded in 1998 – was spun off to form a separate company. In doing this, the Baden-Württemberg energy provider EnBW was following the European Commission’s requirements for the liberalisation of the energy market. The aim was to ensure the economic independence of the transmission grid operators and enhance competition.

Over the last five years, our workforce has grown in number from barely 340 to the current total of 1,205 employees. That is further proof of the growth and economic success of our youthful enterprise.

The heart of the transmission grid

Securely operating the transmission grid is of utmost importance in our work. Grid service and system management ensure that works in substations or on masts are synchronised with our main control centre, which controls the entire grid.
