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.

Zuid-West 380 kV West

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).

Facts

Construction

  • 48 kilometer 380 kV connection between Borssele and Rilland

Afbreken

  • 21 kilometer 150 kV connection between Willem-Anna-Polder and Rilland
  • 21 kilometer 380 kV connection in the 'Zak van Zuid-Beveland'
  • 131 pylons

Planning

  • 2016 Start build substation Rilland
  • 2017 Start build Borssele Rilland
  • 2020 Start build Rilland Tilburg

About the project

New high-voltage line between Borssele and Tilburg

For some time now, the Ministry of Economic Affairs and the Ministry of Infrastructure and the Environment have been working with TenneT on a route for the planned new high voltage line between Borssele and Tilburg.

The existing Borssele–Tilburg line has insufficient future-proof connection capacity for new large-scale conventional electricity generation and large-scale offshore and onshore wind energy projects. This applies not only to future projects in the Borssele region but to the entire province of Zeeland, including Zeelandic Flanders (the part of the province bordering Belgium, which includes a large industrial zone near Terneuzen).

TenneT is obligated by law to connect new energy suppliers to the grid. This requires an expansion of the existing 380 kV line between Borssele and Tilburg with a second 380 kV connection.

Risks if the situation remains “as is”

Currently, the full capacity of the high-voltage grid in the Borssele region is utilized for electricity transmission. This means that maintenance work can no longer be carried out on the high-voltage lines without imposing significant production restrictions. It is not possible to coordinate simultaneous maintenance work on production units and the high-voltage grid without considerable economic impact, and long-term postponement of maintenance work may eventually jeopardize the security of supply.

The new South-West 380 kV high-voltage connection is therefore essential in order to prevent problems affecting the electricity supply in the Netherlands. The major power failure on 27 March 2015 in North Holland province has once again demonstrated the importance of a robust electricity grid to the functioning of modern society.

Subprojects

The project is divided into two subprojects: South-West 380 kV West (Borssele–Rilland) and South-West 380 kV East (Rilland–Tilburg). We will also construct a new 380 kV high-voltage substation at Rilland.

This is a separate project with its own planning procedure and integration plan. The South West 380 kV East and South-West 380 kV West connections will then be linked up to this new high-voltage substation.

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.
