The cables, which together measure 18 miles in length, are approaching the end of their operational life. The cable landfalls are located at:
- Carness Bay (Mainland Orkney) to Point of Dishan (Shapinsay)
- Bay of Linton (Shapinsay) to Bay of Holland (Stronsay) across the Stronsay Firth
- Near Holm of Scockness (Rousay) to Point of Huro (Westray) across the Westray Firth
The aim of the consultations was to identify the best value method to replace the electricity submarine cables to maintain a safe and secure supply of electricity that meets the needs of island communities.
The consultation was only about the replacement of submarine cables at distribution voltages that currently serve Orkney – not the potential future development of a transmission cable.
