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 around 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.

Doetinchem - Wesel 380 kV

With three connections with Germany, two with Belgium, one with Norway and one with the England, the Dutch electricity network is an important link in the North European electricity grid. The new line between Doetinchem in the Netherlands and Wesel in Germany is necessary to allow further development towards a Northwest European electricity market, to safeguard the reliability of the electricity system and to exchange sustainable electricity.

About the project

Production and consumption of electricity is increasing

At present, the transmission capacity of the Dutch grid is insufficient to accommodate the growth in electricity production and consumption in the long term. With three cross-border electricity connections (“interconnectors”) with Germany, two with Belgium, one with Norway, and one with the United Kingdom, the Dutch grid constitutes an important “power hub” within the Northern European grid. A new Dutch-German interconnector is necessary for three reasons:

Further integration of the North-West European electricity market

An integrated North-West European electricity market is an important aim of both the European Commission and the Dutch Ministry of Economic Affairs, because electricity can then be generated at the most cost-efficient location. The new interconnector will enable the Netherlands to play a leading role in the integrated market.

Maintaining the security of supply

If a failure occurs at a large power station in the Netherlands, other power stations must be able to cope with the loss in capacity immediately. Usually this is done by a power station in the Netherlands or another country. Consequently, it is important to have sufficient cross border high-voltage connections.

More capacity for the transmission of renewable electricity

Recent years have seen a significant increase in the amount of renewable electricity generated using wind turbines and solar panels. This is obviously a positive development. If there is no wind, however, or if the wind speeds are too high, wind turbines are inactive. Similarly, solar panels will generate little or no electricity on a cloudy or foggy day. In such situations, alternative sources must be deployed quickly in order to meet the demand for electricity. This is another reason why it is necessary to increase the existing number of cross-border high-voltage connections.

The Doetinchem–Wesel electricity connection will be the fourth interconnector between the Dutch and German high-voltage grids. The importance of the interconnector has been recognized by the EU, which has designated it as a “Project of Common Interest”.

Zuid-West 380 kV Oost

The Ministry of Economic Affairs and the Ministry of Infrastructure and the Environment are cooperating with TenneT in working out a route for the new high-voltage line between Borssele and Tilburg. The line is necessary because the present high-voltage line no longer meets the requirements for a future-proof high-voltage grid. The line consists of two sections called Southwest 380 kV West (Borssele-Rilland) and Southwest 380 kV East (Rilland-Tilburg).

Randstad 380 kV Noordring

By means of the Randstad 380 kV project, we are preparing for the future. This is essential for various reasons. The west of the Netherlands is both a large and growing producer of electricity (Velsen, Maasvlakte and commercial market gardeners) and a big importer of electricity (by means of a cable between Great Britain and the Netherlands). The line consists of two sections, namely the North Ring and the South Ring.

Diemen - Lelystad - Ens

The existing 380 kV Diemen-Lelystad-Ens line will be made suitable to transmit more electricity (including sustainably generated energy). The production of renewable energy, both wind energy and solar energy, exhibits peaks and dips and requires the transmission of electricity over longer distances. This makes it necessary to increase the transmission capacity of the line.
