First prefab concrete column installed at TenneT’s Amaliahaven high-voltage substation

We recently celebrated a major milestone at the new Amaliahaven 380-kV high-voltage substation on Maasvlakte with the installation of the very first prefabricated concrete column.

As SPIE’s construction partner, Cordeel Nederland has been commissioned by TenneT to carry out the building and civil engineering works for this high-voltage substation. The project comprises three sections: two GIS buildings, a connecting building and the surrounding landscaping.

Since April 2024, we have been working on the substructure, including the prefabricated basements of the GIS buildings and the ground floor of the connecting building. For the superstructure, we opted early on for prefabricated concrete construction, enabling us to optimise planning and efficiency. The prefabricated elements are being produced at our own concrete factory in parallel with site construction.

TenneT commissioned this new substation to connect three 2GW offshore wind farms in the IJmuiden Ver Beta, IJmuiden Ver Gamma and Nederwiek 2 wind farm zones. The electricity generated by these wind farms will come ashore at Maasvlakte and be transmitted via converter stations to the Amaliahaven high-voltage substation, where it will be fed into the national high-voltage grid.

Cordeel Nederland is proud to play a key role in this part of the energy transition, which aligns perfectly with our mission.
