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).

In order to ensure the security of supply for Lower Saxony in the future, the transmission capacity of the existing line must be increased by the year 2022.

About the project

TenneT is making the Stade-Landesbergen line fit for the energy transition. The existing Stade-Landesbergen line is a roughly 145 kilometre long supply line between Stade near the Elbe and Landesbergen in the Mittelweser region. Due to the increasing quantity of renewable energy being fed into the grid, the transport capacity of the line is no longer sufficient. In order to ensure the security of supply for Lower Saxony in the future, the transmission capacity of the existing line must be increased by the year 2022. The existing 220 kV line will therefore be replaced by a higher-capacity 380 kV line. The old towers and lines will be completely removed.

The approval for the Stade-Landesbergen line will be issued in two consecutive processes: The Office of Regional Development (ArL) in Lüneburg will define a “route” – i.e. the physical path of the power line – for the Dollern-Landesbergen section within a regional planning procedure. The exact location of the line within the route and thereby the precise tower locations will only be determined in the subsequent planning approval procedure. This procedure will follow the regional planning procedure and will be carried out by the Lower Saxony road construction and transportation authority in Hannover.
