Advanced Notice of Road Closures

SSEN Transmission would like to make you aware of some upcoming planned road closures in the area. As part of the ongoing work at Carradale substation, we will be transporting grid transformers along the B842 between the substation and the start of the Cross Kintyre haul road. To allow these abnormal loads to be transported safely, this section of road will be closed by Police Scotland for approximately 20 minutes on the following day:

Monday 15th August 2022

At the present time we do not have specific details regarding the times of these road closures. If you would like any further information please do not hesitate to get in touch with the Community Liaison Manager, Caitlin Quinn (Caitlin.Quinn@sse.com, 07901135758).

 

About the project

The aim of this project is to reinforce Carradale Substation in order to enable renewable generation connection requests. The project elements include:

  • Replacement of two 60 MVA rated transformers replaced with two 120MVA transformers by the end of 2020
  • Replacement of two 90 MWA rated transformers replaced with 120MVA transformers by Summer 2022
  • Minor modifications  to existing equipment to accommodate the larger transformer size, including earthing, fencing, positioning and substation equipment works.
  • Associated 33kV cabling works will also be required to enable the connection of contracted renewable developments in the area.

 To undertake the works, a site compound will be required for the duration of the project. This will be implemented in advance of construction and installation works and decommissioned once all necessary works are complete. The compound will comprise of site welfare and laydown facility and will be situated in close proximity to the existing grid supply point. Enabling works are due to take place throughout the end of 2019 into early 2020. 

 

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.

Requests have been made to National Grid by a number of wind farm developers in Argyll and Bute for grid connections in the Argyll and Kintyre area. We are responsible for providing the infrastructure required to connect the wind farms to the electricity network. In order to facilitate these connections, reinforcement of the existing transmission network, owned and operated by Scottish Hydro Electric (SHE) Transmission is required.

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 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.

Argyll and Bute Information Sharing Webinar

On Wednesday 17th March, SSEN Transmission hosted an Argyll and Bute Information Sharing Webinar, to provide local stakeholders with an interest in future electricity network plans for Argyll and Bute the chance to join us to hear about our stakeholder-led plans for the future and receive an update on the current construction and operation activities in the region. For those who were unable to attend, we have uploaded a recording of the session which you can view by clicking on the adjacent video.

Notice of Road Closure - Dec 2020

As part of our ongoing Carradale Substation Project, we will soon be assembling the first transformer on site. The delivery of the transformer will mean a section of the B842 will be closed between approximately 9.30am – 11.00am on Monday 14th December 2020. To find out more, please see our full notice on the Project Documentation tab. For any questions, please do not hesistate to contact the project Community Liaison Manager.

Preliminary Construction Activity

Work is due to commence on the Carradale Substation this week with activity contained to the substation compound where our contractors Omexom are due to be on site, breaking out existing concrete bases. This work will continue into W/C 24th Feb, where field drainage will commence in the North field. Once drainage is completed, a hard standing area for welfare will be created in North field which will require HGV stone deliveries for around a fortnight from W/C 9th March. Welfare will then be delivered to site and set up, which will involve HGV deliveries of cabins and a new passing place will be created which will require temporary road works on the B road, likely in the form of stop go boards.

Carradale Community Open Day - Planning for Your Future

Representatives from SSEN Transmission were kindly invited to attend the Carradale Community Open Day by East Kintyre Community Council and attended to present plans for the Carradale Substation Project. Staff members enjoyed a warm welcome and a chance to meet with many of the local community members whilst also having a chance to find out more about upcoming development plans in East Kintyre.
