About the project


The aim of the Dunoon Overhead Line Rebuild project is to replace the existing overhead transmission network line which connects Dunoon to the wider national grid

The existing overhead line is supported by an old design suite of metal lattice towers (often referred to as pylons) which are coming toward the end of their operational life. 

Through studies looking at reconducting the line, we have established a requirement to rebuild the overhead line with different support structures to ensure security of supply.

During the rebuild of the replacement overhead line, we will still require to maintain supply to Dunoon, and so we will required to rebuild the overhead line on an alternative alignment to the existing. As such, we will require a new Section 37 consent from the Energy Consents Unit of the Scottish Government.

The double circuit 132kV overhead line crosses from Scottish Power Energy Networks licenced area to our operational area as it crosses Loch Long from Gairlochhead. As part of the reinforcement project, we are also proposing to reconductor (replace the wires which carry current on the line) this part of the line and maintain the existing towers at either side of the crossing.

Therefore the main project elements therefore are as follows:

  • Construction of a new 132kV overhead line from the existing Loch Long crossing to Dunoon Grid Supply Point, located near Sandbank
  • Reconductoring of the Loch Long crossing
  • Decommissioning/removal of the existing 132kV overhead line
  • Associated tie in works at Dunoon Substation will also be required


Our Approach

Throughout the life of our projects, we aim to work positively with local communities and keep people informed about what we are doing. This is particularly important when we are developing a project and we want to understand what local people think about our plans.

We endeavour to take the time to discuss our proposals with local community councils and the wider affected community and to carry out engagement at key stages, listening to feedback before finalising project plans.

We aim to begin the public consultation process for these works in Autumn 2020, where we will present further information regarding our proposals and will do our best to answer any questions and address issues or concerns brought to our attention.


Who is Scottish and Southern Electricity Networks?

Scottish and Southern Electricity Networks is the trading name of Scottish and Southern Energy Power Distribution Limited, Scottish Hydro Electric Transmission plc, Scottish Hydro Electric Power Distribution plc and Southern Electric Power Distribution plc.

How are proposals scrutinised?

The Scottish Ministers are responsible for determination of applications submitted under Section 37 of the Electricity Act 1989. Both statutory consultees and members of the public have the right to submit their representations on the application. All representations will be considered by Scottish Ministers in their determination of the application.
The Office for Gas and Electricity Markets (Ofgem), as the regulator, has to approve all investment so project proposals are developed under license conditions.
Preferred route corridors chosen will comply with revised ‘Holford Rules’ which are the recognised industry approach to routeing overhead lines amended to reflect Scottish circumstances.

How and to what extent are electricity consumers' interests considered?

SHE Transmission are regulated by the Office for Gas and Electricity Markets (Ofgem), the regulator responsible for representing consumers' interests. Electricity consumer interests are therefore one of our key drivers and this is enshrined in our statutory duties under the Electricity Act.

In particular we have a statutory duty to develop, maintain and operate an efficient, economic and co-ordinated transmission system. Since the costs of these projects will ultimately be paid for by electricity consumers, we have a responsibility to take cost into account with due weighting in a comparison against other important factors.

What is the transmission network?

It’s the highest voltage electricity network in the UK – the ‘motorway network’ of the energy world. It transmits large quantities of electricity over long distances via wires carried on a system of mainly metal towers (pylons) and large substations. Transmission voltages in Scotland are 132kV, 275kV and 400kV. Larger generation schemes usually connect to the Transmission system.

The lower voltage parts of the system are called distribution networks. In Scotland, these local networks operate below 132kV whereas in England the distribution network includes 132kV. 


Stakeholder Engagement Strategy Review - Feedback

Stakeholder Engagement Strategy Review - Feedback

The following form presents an opportunity for you to directly influence the strategy – providing input into specific areas of interest – therefore, please answer as many questions as you like. The responses will be used to develop our stakeholder engagement strategy and will help us set specific targets for each objective. Please note that individual responses will not be published but the findings will be included in the final strategy.
