Submarine Electricity Cable replacement works

Fifty-nine Scottish islands are connected to the mainland electricity network via submarine electricity cables. 

As these cables naturally come to the end of their operational life, Scottish and Southern Electricity Networks make arrangements to replace them to ensure a continued reliable electricity supply to Scotland’s islands.

The introduction of Scotland's National Marine Plan (2015) means we may need to change the way we install new or replacement cables within the marine environment. 

We are committed to consulting with all parties who have an interest in how these cables are installed, from the customers who rely on the electricity to the marine users who may be impacted.


Submarine Cable Safety Event

The submarine cables team recently hosted a safety event for all our contractors. The day, which focussed on behaviours and how we all work safely, was a great success and is sumarised in the video below.

Clyde cable replacements

Following on from the pre application public consultation events in May 2018, surveys have been taking place on the proposed cable rotues for the replacements between Bute to Cumbrae and Carradale to Arran in the Firth of Clyde.


The surveys will inform the final proposals prior to submission of marine licence applications for both projects later this year.


You can view the proposals for both cable replacements in the document library.
