The first new high-voltage tower (Wintrack mast) was installed in the village of Rilland in the Dutch province of Zeeland on 25 April. It is the first of a total of 114 Wintrack masts that will provide a new high-voltage connection between Borssele and Rilland in the coming years. Several VolkerWessels companies are involved in the project. Main contractor Van Hattum en Blankevoort is collaborating with partners VolkerInfra, KWS, Volker Staal en Funderingen and Aveco de Bondt on building the first 12 crucial mast foundations needed for the activation of the new high-voltage station at Rilland. The masts themselves will be supplied and installed by VolkerWessels Telecom. A landmark in every sense for both TenneT and Zeeland!

To enable the new high-voltage station at Rilland to be hooked up to the existing high-voltage connection later this year 12 Wintrack masts are currently being installed in the vicinity. In recent months the partners have been working hard on the foundations of the 12 masts and the ancillary works, including the construction of roads and sites and necessary temporary structures (e.g. sheet piling) along with community engagement and project management.
Landmark for the project and the province
Once this stage has been completed VolkerWessels Telecom can start erecting the masts. Each consists of several parts which will be delivered to the building site by special transport, before being lifted on top of each other one by one and assembled. Full assembly of the first Wintrack mast, consisting of two pylons, was completed on 25 April. When driving past Rilland on the A58 you can hardly miss it! As the very first Wintrack mast in Zeeland, it is a landmark for the project and province. The other 11 Wintrack masts will arise in the landscape one by one over the next weeks. You can read more about the process of constructing a high-voltage mast here.
The construction of the Rilland high-voltage station is almost complete. The 12 new masts will enable the current high-voltage connection to be hooked up to the new high-voltage station at Rilland by the end of the year, so that it can come on stream. This will create three separate connections: to Borssele, Geertruidenberg and Zandvliet (Belgium), respectively. These will replace the current single connection, making for more flexible energy distribution.
Sealing the contract
The installation of the first new Wintrack mast marked the official sealing of the contract between TenneT and the consortium consisting of VolkerInfra Rilland (VHB and KWS), VolkerWessels Telecom and SPIE Nederland. A great follow-up to the Randstad 380 kV project, which is also being realised by various VolkerWessels companies on behalf of TenneT.
The project that goes by the name of Rilland 380kV concerns the realisation of essential new connections between the existing grid to the new high-voltage station at Rilland. These connections are essential for the national and international power supply because they guarantee continuous availability of transport capacity.
A joint effort
KWS Infra Roosendaal-Sas van Gent will prepare the ground and build the roads around the new masts and the part scheduled for demolition. Van Hattum en Blankevoort will be responsible for realising the foundations and the associated civil engineering works for the 12 high-voltage masts close to the Rilland high-voltage station. The station was designed by VolkerInfra in collaboration with TenneT, while the vibro combination piles will be installed by Volker Staal en Funderingen. The masts will be supplied and installed by VolkerWessels Telecom.
