Proposals submitted to renew isles power cable

Plans to replace the existing submarine electricity cable connecting Rousay and Westray, have been submitted by Scottish and Southern Electricity Networks (SSEN).

Operating as Scottish Hydro Electric Power Distribution, SSEN recently submitted the application to undertake the replacement to Marine Scotland.

According to SSEN, the existing subsea cable, which was installed back in 1983, is now reaching the end of its operational life and the energy company is proposing to install a new submarine electricity cable from Scockness on Rousay to East Sous on Westray.

The proposed replacement involves underground cabling at both shore ends with the cable then laid across the surface of the seabed.

The cable will be buried where sediment allows, with rock bags placed at regular intervals where seabed conditions are not suitable for burial.

According to SSEN, their plans would see the work completed within the first six months of next year and the project would also be scheduled to minimise disruption on local marine life, avoiding the key breeding seasons for both local seals and key bird populations.

It is hoped there will be no disruption to the power supply on the two islands, however, if there is SSEN has said it will inform those who would be affected ahead of time.

Kirstine Wood, Lead Engagement and Submarine Policy Manager, said: “We are delighted to have submitted our application to replace the Rousay to Westray submarine electricity cable which will secure electricity supplies for the island communities for many years to come.

“The proposed route and installation methods have been carefully designed to balance stakeholder feedback and environmental constraints whilst meeting electricity licence obligations.
