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.
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.
