Three types of cables would be used:
• Inter-array cables connecting groups of turbines to the offshore substations
• Export cables for transmitting electricity from the offshore substations to shore
• Onshore cables to connect to the onshore substation

The wind turbines would be connected to each other by buried inter-array cables that carry the electricity to offshore substations where the voltage is increased. Up to six export cables would then carry the power from the offshore substations to shore, a distance of around 50km (31 miles). Cables will typically be buried at a depth of between 0.5m and 3m, subject to local conditions.

The export cables would be connected to a proposed new onshore substation at Cleve Hill, near Graveney in Kent.
