Making the grid future-proof
TenneT is constructing the Randstad 380 kV high-voltage connection to make sure the grid is “future-proof”. We have decided to undertake this project for various reasons. The highly urbanized western part of the Netherlands (i.e. the Randstad conurbation) produces a large and growing amount of electricity (e.g. at the Velsen and Maasvlakte power plants and by the horticultural industry), but is also a major importer of electricity (via the subsea BritNed cable between the UK and the Netherlands). It is important that this electricity can be transported via a reliable grid within the Netherlands and throughout Europe.
The demand for transmission capacity has increased due to the liberalization of the European energy market. This has resulted in more electricity being transmitted across longer distances. The Randstad 380 kV connection will also help us to connect offshore wind farms to the onshore grid, and accommodate the growing share of renewable electricity generated using solar panels, for instance.
New substations at Beverwijk and Beverwijk
There are a number of high-voltage substations along the Beverwijk–Vijfhuizen route that convert electricity from 380 kV to 150 kV for regional distribution, and that monitor and safeguard grid stability. A new 380 kV high-voltage substation is being constructed for this purpose at Beverwijk.
The new Vijfhuizen substation will be located on the south side of industrial estate “De Liede”, in the triangle formed by the existing 150 kV transformer substation, Spaarnwouderweg, and the N205 secondary road.
The two transformer substations at Vijfhuizen and Beverwijk must be completed before the Beverwijk–Bleiswijk connection can be taken into operation.
