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).

Our grid

TenneT manages the high-voltage grid in the Netherlands and large parts of Germany. TenneT transmits electricity at 110,000 volts (110 kV) and higher. With over 22,000 kilometres of high-voltage lines, we cross borders and connect countries.

Electricity market

The energy sector is developing rapidly. The process of European market integration began some years ago. Its purpose is to create a single European market that enables market parties to trade gas and electricity across national borders easily and efficiently.

Transparency data

We provide transparency data on our operations on our Dutch and German transparency page and on ENTSO-E.

New, high-capacity lines are required to bring the energy produced in Lower Saxony and Schleswig-Holstein to the consumers. The grid connection points Halbemond and Emden/Ost should therefore be connected in the future by a 380 kV line.

About the project

All German nuclear power plants should be shut down by 2022. Germany would like to sustain itself in the future without nuclear energy and produce energy more extensively from renewable sources. In addition to solar energy, a particular focus is placed here on power from wind turbines. The share of wind energy in electricity production is therefore constantly increasing. No other German state has as many wind turbines as Lower Saxony.  

Because the grid region of TenneT ranges from Schleswig-Holstein in the north to Bavaria in the south, TenneT has a special role to play in the energy transition.
