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.
Cost Benefit Analysis consultation
For the past three years, we have been working collaboratively with our stakeholders to develop a Cost Benefit Analysis methodology which allows us to model the value to society of different engineering practices. We use the output to help us find the most sustainable cable installation and protection method for each cable we replace.
In response to feedback, we have strengthened the model to reflect:
• Increased health costs associated with increased fuel poverty
• Seabed natural capital value
This is an opportunity to review changes and provide feedback on the approach.
We're out and about in Orkney this week - keeping the community up to date about plans to replace the submarine electricity cable between Rousay and Westray.
