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.

Services in Germany

TenneT is the driving force behind the Energiewende, the transition to a sustainable energy supply in Germany.

Transmission services

TenneT is responsible for the construction and maintenance of the high voltage grid that is used to transport large quantities of electricity in large parts of Germany. This grid functions as the “highway” of electricity transmission and connects to the lower-voltage distribution grids and to certain large industrial users. In addition, TenneT builds and maintains several cross-border interconnectors with neighbouring countries. We also play a key role in the implementation of the German energy transition. TenneT is responsible for connecting a large number of offshore wind farms and for a considerable share in building the onshore connection capacity that is required in this context. 

System services

TenneT operates the high voltage electricity system. Because electricity is hard to store, supply and demand must continuously be kept in balance. TenneT ensures this balance 24/7, 365 days a year.

Facilitating the energy market

TenneT's third task is to facilitate a smoothly functioning, liquid and stable electricity market, and to support the large-scale transition to renewables.
