The Dudgeon Offshore Wind Farm generates sufficient electricity to power more than 410,000 UK homes. This electricity has to be transmitted from the wind farm to an onshore substation from where it can then enter the National Grid.
A seabed cable transmits this electricity from the offshore substation to landfall at Weybourne Hope in North Norfolk. From there an underground cable carries the electricity to a new substation constructed on the outskirts of the village of Necton, near Swaffham in the Breckland district of Norfolk. The cable is 30 miles long. and it is buried in ducting at a depth of 1.4 metres under land belonging to 44 individual landowners.
