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.

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.

Facts

Connection

  • New 150 kV underground cable
  • New and reconfigured high power stations
  • 2018 ready

 

 

Construction

  • 58 Km new 380 kV connection
  • Of which 9.3 Km underground cabling
  • 32 Km 150 kV underground cabling
  • Remove old 150 kV connection (pylons)

About the project

Making the grid future-proof

TenneT is constructing the Randstad 380 kV high-voltage connection to make sure the grid is “future-proof”. We have decided to undertake this project for various reasons. The highly urbanized western part of the Netherlands (i.e. the Randstad conurbation) produces a large and growing amount of electricity (e.g. at the Velsen and Maasvlakte power plants and by the horticultural industry), but is also a major importer of electricity (via the subsea BritNed cable between the UK and the Netherlands). It is important that this electricity can be transported via a reliable grid within the Netherlands and throughout Europe.

Transmission capacity

The demand for transmission capacity has increased due to the liberalization of the European energy market. This has resulted in more electricity being transmitted across longer distances. The Randstad 380 kV connection will also help us to connect offshore wind farms to the onshore grid, and accommodate the growing share of renewable electricity generated using solar panels, for instance.

New substations at Beverwijk and Vijfhuizen

There are a number of high-voltage substations along the Beverwijk–Vijfhuizen route that convert electricity from 380 kV to 150 kV for regional distribution, and that monitor and safeguard grid stability. A new 380 kV high-voltage substation is constructed for this purpose at Beverwijk and Vijfhuizen.

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).

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.

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.
