A new seabed export cable will bring the electricity generated by both the Sheringham Shoal and Dudgeon Offshore wind farm extensions to shore on the coast of Norfolk. Currently Equinor is looking at two landfall alternatives in Weybourne and Bacton.
From there a new underground cable will be installed to transmit that power to a new purpose built onshore substation, which will be located within a 3km radius of the existing Norwich main substation, south of Norwich. This will be the National Grid network connection point for the electricity from both wind farm extensions.
The power will be transmitted from landfall to the substation using an HVAC system which eliminates the need for any relay stations along the onshore cable route.
Equinor is currently investigating both landfall options and plans to take a decision of its preferred landfall location in 2020.
