In Suffolk, our proposals include:
- a connection from the existing transmission network via the proposed Friston substation, including the substation itself. The proposed Friston substation already has development consent as part of other third-party projects. If the proposed Friston substation has already been constructed under another consent, only a connection into the substation would be constructed by Sea Link
- a high voltage alternating current (HVAC) underground cable of approximately 1.7 km in length between the proposed Friston substation and a proposed converter station
- a 2 GW high voltage direct current (HVDC) converter station up to 26 metres high plus external equipment (such as lightning protection and railings for walkways) near Saxmundham
- a HVDC underground cable connection of approximately 10 km in length between the proposed converter station near Saxmundham, and a transition joint bay approximately 900 metres inshore from a landfall point where the cable transitions from onshore to offshore technology
- a landfall on the Suffolk coast (between Aldeburgh and Thorpeness).
Our proposals in Suffolk have been developed for Sea Link as a standalone project, but also include opportunities to co-locate infrastructure for up to two further projects at the converter station, along the cable corridors and at the landfall location.
