Our key tasks

We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).

Offshore 2030

In the summer of 2020, the German government decided to push ahead with the expansion of offshore wind energy, not least to achieve the goals of the 2030 climate protection programme. At the same time, the federal government has also set higher targets: Thus, the originally planned capacity of 15 gigawatts (GW) for 2030 increases to 20 GW, and for 2040 even 40 GW are planned. Therefore, not only new offshore wind farms are needed, but also new lines connecting them to the transmission grid.

One of these new connections is being prepared in the BorWin6 project with 930 megawatts (MW) of transmission capacity. The route for this project runs from the seaward converter station BorWin kappa over 235 kilometres to Büttel in Schleswig-Holstein.

Especially for the upcoming grid connection projects with a capacity of 2 GW, further routes are needed in addition to those used and already planned. In the "Seetrassen 2030" project, new route corridors are to be developed for future offshore grid connection systems in Lower Saxony's coastal sea. As the connection of these future systems to the transmission grid will take place either in the control area of Amprion or TenneT, the companies jointly submitted an application for the implementation of a regional planning procedure (ROV) in December 2020. Detailed questions and answers can be found here.
