The transmission system operators

The TSOs plan and maintain the extra-high voltage grid and regulate grid operations. They contribute their expertise and experience towards ensuring the secure expansion of the grid and are thus responsible for the security and stability of the German power supply system. This means they must guarantee the uninterrupted exchange of electricity across all regions using their power lines and also ensure that generation and consumption levels are balanced at all times. Over the coming decades, the main task of the four TSOs will therefore be to establish an energy supply infrastructure for Germany that is fit for the future and equipped with up to date, efficient and environmentally friendly technology.

50Hertz operates the extra-high-voltage grid in northern and eastern Germany and is extending it to meet the needs of the energy transition. The 50Hertz grid area includes the federal states of Brandenburg, Mecklenburg-Western Pomerania, Saxony, Saxony-Anhalt and Thuringia as well as the city states of Berlin and Hamburg. In these regions, 50Hertz and its employees secure the electricity supply for 18 million people around the clock. 50Hertz is thus responsible for one of the largest electricity export regions in Europe and is leading in the integration of electricity from renewable energies.

From the Control Centre in Neuenhagen near Berlin, the grid is controlled and monitored. The company’s headquarter is in Berlin.

50Hertz is responsible for connecting the German offshore wind farms in the Baltic Sea to the grid and even some Offshore-Windfarms in den North Sea. The first commercial offshore wind farm in the Baltic Sea, EnBW Baltic 1, has been officially in operation since May 2011.

From its headquarters in Dortmund, Amprion operates the extra-high voltage grid in seven German states – from the North Sea to the Alps on the border with Austria and Switzerland. Amprion transports electricity to around 29 million people and thus makes an important contribution to a stable and secure electricity supply in its grid area.

Due to its central location, Amprion performs important tasks for the integrated grid systems in Europe and also plays an important part beyond the borders of its own grid area: From its company locations in Dortmund and Brauweiler near Cologne, the company carries out vital tasks in coordinating Germany’s four control areas as well as in the field of international energy transport.

Amprion is preparing the way for the energy transition and driving forward the expansion of the grid. As part of this, several offshore wind farms in the North Sea are being connected to the transmission grid.

As a leading European grid operator, TenneT is committed to providing a secure and reliable electricity supply – 24 hours a day, 365 days a year. TenneT is the first cross-border transmission system operator to plan, build and operate a high and extra-high voltage grid in the Netherlands and large parts of Germany.

The German grid area mainly comprises the federal states of Bavaria, Bremen, Hesse, Lower Saxony and Schleswig-Holstein as well as parts of North Rhine-Westphalia. TenneT facilitates the European energy market through interconnectors to neighbouring countries. TenneT's employees ensure that more than 43 million people can rely on a stable electricity supply.

As one of the largest investors in the expansion of national and international onshore and offshore electricity grids on land and at sea, TenneT is driving energy transmission towards a climate-friendly energy system.

In Germany and the Netherlands, TenneT provides the connection capacity for offshore wind energy in the North Sea as a cross-border transmission system operator.

TransnetBW GmbH operates the electricity transmission grid in Baden-Württemberg and thus secures the electricity supply in the region, in Germany and in Europe. Among TransnetBW's customers and partners are electricity traders, power plant and distribution grid operators in Germany and abroad.

Around 80 transformers connect the TransnetBW transmission grid to the distribution grids in Baden-Württemberg. Major international industrial enterprises and more than 11 million people in Baden-Württemberg are reliably supplied with electricity around the clock via these access points. As a result, TransnetBW secures the economic strength and quality of life in south-west Germany.
