Project 3: High-voltage connection in the Randstad conurbation

---

The route of the south ring of the Randstad 380 kV high-voltage line between Beverwijk and Wateringen was finalised in 2008. Besides a northern section totalling some 65 kilometres, the high-voltage connection also includes a southern section of approx. 20 kilometres which will run from Wateringen to Bleiswijk, and from Bleiswijk to Beverwijk. The high-voltage connection will be built largely above-ground using new, innovative Wintrack pylons. In addition, TenneT will be laying approximately 20 kilometres underground, which is regarded as extremely innovative, even in an international context. TenneT will be monitoring the behaviour of the underground cables in collaboration with Delft University of Technology.
