Sheirdrim Wind Farm Connection Virtual Consultation


Thank you to those who participated in our recent virtual pre-application consultation exhibition. This has helped us to gain views and feedback on our proposals for the Argyll and Kintyre 275kV Substations and the proposed Sheirdrim Wind Farm Connection Project. 

Live IM chats with the project team were held on the 8th and 9th December 2021 via our virtual consultation room which is still available to view, or you can click here to view our consultation booklet. 

Our consultation period closed on Monday 10th January and all feedback received will be collated, reviewed and included in a report on Consultation.

If you have any queries about the virtual consultation that took place, or if you would like us to send you a paper copy of the consultation booklet, please contact the Community Liaison Manager.



About the project

We are developing a project which will seek to connect Scottish Power's Sheidrim Wind Farm located west of Claonaig, in Argyll to our SSEN Transmission network

The 84MW windfarm requires a single circuit 132kV overhead line (OHL) connection from the windfarm substation compound to the existing Crossaig 132kV substation, which will be approximately 11km in length.

The proposed project would involve:

  • A possible underground cable (UGC) from the Sheirdrim Wind farm Substation Compound, extending approximately 2 km before converting to overhead line. 
  • Between 8 - 11 km of trident wood poles or steel lattice structures to carry a single circuit 132kV overhead line.
  • Install a 120MVA 132/33kV transformer; a Gas insulated substation (GIS) 33kV transformer Circuit Breaker; and a 33kV Switch Disconnector 
  • Felling commercial forestry to create an operational corridor to enable the safe operation and maintenance of the overhead line.
  • Associated works will include creation of temporary laydown areas for materials and welfare facilities, installation of permanent and temporary access tracks and drainage infrastructure

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 Transmission network upgrades paid for?

Investments in projects are made by SHE Transmission plc. Electricity transmission companies are authorised to recover the costs of such investments through 'use of system' charges which are levied by National Grid Electricity Transmission plc on generators and suppliers of electricity. Suppliers recover their costs from all electricity customers. In order to protect the interests of customers, the transmission companies have to demonstrate to the energy regulator, Ofgem (Office for Gas and Electricity Markets) that proposed investments are necessary, are efficient and are economical so that the charges which are ultimately levied on all electricity customers are justified.

This means SHE Transmission is subject to a funding mechanism established by Parliament and regulated by Ofgem. Cross subsidies between different businesses in the SSE group is not permitted.

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.

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. 

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.

Virtual Consultation

We are launching a pre-application consultation exhibition to gain views and feedback on our proposals for the Argyll and Kintyre 275kV Substations planning application. Alongside this we shall also be introducing and seeking views on the proposed Sheirdrim wind farm connection project. SSEN Transmission would like to invite you to attend our virtual consultation events where you can view our proposals online using our virtual consultation room. To find out more, please visit the project overview section of this website.
