Warwick Energy is considering a second site for substation near Swaffham.
This is the reason why the company is launching public consultations prior to submitting application for the full planning permission, reports EDP24.
If approved, the substation will connect GBP 1.5bn Dudgeon offshore wind farm to the grid.
A proposal for the substation nearby Little Dunham, as well as onshore cable plans, was rejected.
The Dudgeon wind farm is located approximately 32km offshore of the north Norfolk coast, with the town of Cromer being the closest settlement on land. Depending on the size of wind turbine generators installed offshore, the Dudgeon project could have a total installed capacity of up to 560MW.
