Project Overview

A request has been made to National Grid by the Developer of Aberarder wind farm for connection to the transmission network. We are currently contracted to provide a 132kV connection running from the proposed wind farm.  The sole use infrastructure works involve approximately 5.25km of new 132kV overhead line to be constructed between the new wind farm substation and a new 132kV indoor switching station to be established at the Dunmaglass wind farm 132kV feeder circuit from Farigaig substation.

Why is the Project Required?

SSEN Transmission are the licensed owner of the electricity transmission network in the north of Scotland, our licence obligations include maintaining the existing network to ensure that the lights stay on and investing in the network to provide the infrastructure needed to allow generation developments to connect it.

The transmission network gathers energy in from power stations, hydro-electric generation schemes and wind farms and carries it to areas where it is to be used. We work with the Transmission System Operator, National Grid, who is responsible for operating the transmission network across the whole of Great Britain, to make sure that power flows smoothly and reliably across our network.

As part of its statutory and Transmission Licence obligations, SSEN Transmission has several duties including:

· The development and maintenance of an efficient, coordinated and economical system of electricity transmission,

· To facilitate competition in the supply and generation of electricity, and

· To ensure that the security of the network is maintained as the demand and/or generation connections change over time.

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.

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.

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.

Section 37 Application

SSEN Transmission has applied to the Scottish Ministers for consent under Section 37 of the Electricity Act 1989 to construct and operate approximately 5.25km of single circuit 132kV overhead line between the proposed Aberarder wind farm substation and the existing Dumnaglass woodpole 132kV trident line. A copy of the application, with a plan showing the land to which it relates, is available for public inspection in person, free of charge, during normal office hours at Highland Council Inverness Service Point Normal office hours Monday, Tuesday, Thursday & Friday: 9 am - 5 pm Wednesday: 10 am - 5 pm Town House Castle Street Inverness V1 1JJ and Farr Community Hall Inverarnie Park Farr IV2 6XF The application can also be viewed at Any representations to the application may be submitted via the Energy Consents Unit website at by email to the Scottish Government, Energy Consents Unit mailbox at or by post to the Scottish Government, Energy Consents Unit, 4th Floor, 5 Atlantic Quay, 150 Broomielaw, Glasgow, G2 8LU, identifying the proposal and specifying the grounds for representation. Written or emailed representations should be dated, clearly stating the name (in block capitals), full return email and postal address of those making representations. Only representations sent by email to will receive an acknowledgement. All representations should be received not later than 22nd July 2019, although Ministers may consider representations received after this date.
