About the project

The  Stronelairg wind farm connection project comprises of four key elements:

  • Construction of a new substation within the Stronelairg windfarm development to channel generated power via underground cable to new Melgarve Substation (complete)
  • Construction of a new substation at Melgarve, near Garva Bridge, to facilitate the connection of Stronelairg wind farm to the National Grid (in progress)
  • Construction of a new 10km 132kV underground cable  to establish connection between the new Melgarve substation and the new Stronelairg substation (complete
  • Modify a tower on the existing Beauly – Denny overhead line to facilitate a connection to the new Melgarve Substation (complete)


Developing and building our projects in the right way

Whilst the project is moving at pace, specific care and attention is being made towards ensuring the local environment is being protected from unnecessary disturbance or damage. Protection measures implemented to date include:

  • construction of deer fencing;
  • creating and monitoring of buffer zones to protect species such as Water Voles; and
  • building sediment traps to keep watercourses clear.

Why is the project required?

As the transmission licence holder in the north of Scotland we have a duty under Section 9 of the Electricity Act 1989 to facilitate competition in the generation and supply of electricity. We have obligations to offer non-discriminatory terms for connection to the transmission system, both for new generation and for new sources of electricity demand.
The aim of the project is to enable Stronelairg wind farm to connect to our transmission network. Under our Network Operators Licence this connection should be efficient, co-ordinated and economic, whilst having the least possible impact on the environment.

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.

What are The Holford Rules?

The Holford Rules originated in 1959 as the result of work by Lord Holford, a part-time member of the Central Electricity Generating Board (National Grid's predecessor). The Holford Rules have been augmented by both National Grid and SHE Transmission plc to reflect environmental legislation and best practice in recent years. We have continued to use them as a valuable set of guidelines for reducing the impact of our assets on landscapes.
The guidance recommends appropriate application of the Holford Rules to inform routeing. These rules advocate the application of a hierarchical approach to routeing which first avoids major areas of highest amenity, then smaller areas of high amenity, and finally considers factors such as backdrop, woodland and orientation. The Holford Rules apply the term ‘amenity’ to refer to environmental designations and classifications such as Natura 2000 sites, Sites of Special Scientific Interest (SSSI), Scheduled Monuments, Listed Buildings, National Parks.
The guidance also recognises that the key effect of overhead lines is visual and it advises that the routeing of overhead lines should consider the types of mitigation (screening) that could offset any visual effects.
In their National Policy Statement EN-5, the Government has stated that the Holford Rules “should be followed by developers when designing their proposals.” Their use is therefore Government policy, rather than a voluntary choice of SHE Transmission plc.

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. 

Re-Scheduled Delivery

The planned delivery of a transformer unit between Inverness and Stronelairg Wind farm on Sunday 6 August, has been rescheduled to take place on Tuesday 8 August. The specialist deliveries are a complex and timely operations which will be under the supervision of Police Scotland and specialist haulier, Allelys. To ensure that the deliveries are made safely, and with the minimum of disruption, a rolling road block will be implemented by Police Scotland and traffic will be able to pass with care under their instruction. Delivery Route Tuesday 8 August - Depart Inverness at 05:00 Travel via A82 to Fort Augustus Turn left onto B862 at Fort Augustus and continue onto Stronelairg wind farm site, arriving at approximately 08:00 If you have any questions about the upcoming operation, please do not hesitate to contact a member of the Community Liaison Team.

Transformer deliveries

We are transporting 2 x supergrid transformers in stages over three weekends in July and August from Port of Corpach to Melgarve Substation. View the full details in our 'Project Documentation' tab.

Transformer deliveries

We are transporting 3 x transformers from Inverness to Stronelairg substation on Sunday 6th and Sunday 13th August. View the full details in our 'Project Documentation' tab.

Delivery activity

The Melgarve substation construction team are preparing for a series of important deliveries which are required to connect the Stronelairg wind farm to the national grid. The deliveries will include 10km of underground cables and two transformer units which weigh 110 tonnes. Please see 'Project Documentation' for full details..

A Walk on the wild side...

An exploration of the Spey Dam reservoir and the surrounding area with the Melgarve substation onsite Ecologist. Come and discover what monsters live in the Loch, find out if we’ve trapped any mammals and much more… please see "Project Documentation" for further details.

Cabins at Stronelairg

A unique feature of the Stronelairg site is the construction of a 70 bed camp with full catering facilities which will assist in limiting travel time to site and may also be a life line should workers become snowbound on the mountain. Camp set up has now been completed with the accommodation units occupied and the canteen having opened at the beginning of March. By mid April, there shall also be a broadband connection to provide internet connectivity to camp.

Strathmashie Road

Since meeting with community members and listening to their suggestions, the 10mph speed limit on the Strathmashie Road has been extended to the turn off from the A86 to ensure HGVs and other construction traffic is slowing on approach to site and past residential properties.

Construction commencement

Construction teams have begun mobilisation to both Melgarve and Stronelairg sites. This early phase will see the establishment of welfare facilities, delivery of equipment and the creation of secure material storage areas
