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).

Electricity market

Hamburg/Nord-Dollern

The existing line between the transformer substations of Hamburg/Nord in Schleswig-Holstein and Dollern in Lower Saxony is being replaced and expanded.

About the project

Increasing quantities of wind energy are being produced in the German coastal regions. In order for this energy to be transported to the point of consumption, higher-capacity power lines are required. For this reason, the existing line between the transformer substations of Hamburg/Nord in Schleswig-Holstein and Dollern in Lower Saxony is being replaced and expanded. The project has been planned in three phases. These are currently in various stages of planning and construction.
