The construction of the transformer sub-station is making steady progress. Currently the electric cables are being laid inside the building and the switching equipment is being installed. Then the transformer will be installed. This will ensure that the electricity is converted to 150 kV. The transformer sub-station is connected to the regional electricity grid of Continuon. For this purpose the grid has been extended by means of a 7-kilometre long underground high-voltage cable from the transformer sub-station at Wijk aan Zee through Beverwijk to the sub-station close to the Nuon power plant in Velsen-Noord. The sustainably generated electricity gets to your home via the electricity grid.
