Dear Market Participants,

This is an announcement that we will be adding two new contingencies to capacity calculation in all timeframes due to the commissioning of a new substation in Tilburg. These will be considere from Bussinessday 2026-07-24 onwards.

The following CO will become obsolete:

This change concerns only the white circuit for now. When the black and grey circuits are also finalized, a new message will be published with more changed contingencies.

For more information on the new 380kV substation in Tilburg, please visit the TenneT website at Hoogspanningsstation Tilburg 380 kV | TenneT

We trust to have informed you sufficiently.
