The Electrical System connects the offshore array to the onshore grid connection point at the existing National Grid substation at Bicker Fen.
The power generated by the offshore wind turbines is collected by the offshore substation platforms and transformed to a suitable voltage for export, before being exported by sub-sea and underground cabling.
The Electrical System covers the offshore export cable, the underground landfall infrastructure to the north of Anderby Creek, an underground onshore cable system and a new substation near Bicker Fen, ensuring the connection of the offshore turbines to the national grid onshore and ultimately into UK homes.
For further background on the selection of Bicker Fen as the grid connection point, the process carried out to select the site and route for the electrical system infrastructure, and further design developments please click here.
The consent application for the electrical system was accepted by the Planning Inspectorate (PINS) on 21 May 2015. A formal examination of the application was conducted and concluded on 3 March 2016.
