Scottish Hydro Electric Power Distribution Submarine Electricity Cables Consultation What we heard and next steps


Scottish and Southern Energy (SSE) continue the consultation over replacing submarine electricity cables.

SSE have proposed a spend of £44 million over the next eight years to replace 112km of submarine electricity cables. This cost was based on their existing engineering practice of surface laying these cables. However, policies within Scotland’s National Marine Plan may require SSE to change this practice and to protect the whole 112km. The initial high level analysis suggests costs could be in the region of £300 million.

 

SSE want to find the best value method of cable installation which satisfies all current legislation and provides a sustainable balance of health and safety, socio economic environmental and wider engineering and economic impacts. To help model this, SSE propose to use a Cost Benefit Analysis (CBA) model which will be used to demonstrate (to SSE, consumers, the regulators, Ofgem and Marine Scotland, and all users of the marine environment) the method(s) SSE propose to deploy in the future for laying and protecting cables around the coast of Scotland.

 

The public's responses to the first phase of the consultation, which closed on 13 October 2015, have been invaluable and informed:

 

the submarine cable installation methods we consider in the CBA

the benefits and drawbacks of protecting submarine electricity cables

the key impacts associated with installing submarine electricity cables

the methodology we will use to assess impacts

the methodology we will use to identify and evaluate potential impacts

 

SSE have summarised the responses and made them available on their website at http://news.ssepd.co.uk/submarinecables/ .

 

SSE will publish their methodology statement outlining where how it has changed in response to public views and the additional evidence provided to help identify and quantify impacts of different submarine cable installation methods on the 7 December.

 

SSE are also holding a series of workshops, which show how the CBA methodology will be applied to cable routes through worked examples. This will give the public an opportunity to provide face-to-face feedback on the identified impacts and method(s) for quantifying them.
