Overview
Status: Early Development
About the Project
Sloy Power Station was constructed in 1950 and is located on the western shore of Loch Lomond near Inveruglas, Argyll and Bute. The site is located within the Loch Lomond and The Trossachs National Park and can be accessed from the A82.
Our substation is located to the rear of the power station building and is a four-transformer site, which connects 11kV output of the hydro-electric power station to 132kV for export to the transmission network. Sloy Power Station generates around 150 megawatts of renewable power, contributing to Scotland's Net Zero targets.
These transformers are coming to the end of their operational life and need replacing. The consequent deterioration in their condition poses a risk of failure, meaning the power station would no longer be able to generate renewable energy and poses a risk to the reliability of supply to customers.
3D Visualisation of the Project
This video allows stakeholders to visualise the new replacement substation at Sloy. It has been created to increase the transparency of our plans and was on display at the public consultation events.
Project Elements
Delivery of this proposed project includes the following elements:
- A new substation platform surrounded by 2.4 metre security fence
- A new control building and a new switchgear building
- Installation of four new 132kV/11kV transformers and two regulating transformers and an air insulated switchgear to connect them
- Installation of 132kV underground cable connecting the new substation with the existing cables to the West of the site (including beneath the railway)
- Installation of 11kV underground cable connecting the new transformers to the power station
- Removal of the old transformers and associated equipment, including any redundant overhead line apparatus
- Existing access from the A82, which may be subject to upgrade
- Temporary/permenant access tracks to facilitate development as well as site drainage infrastructure and temporary construction compounds
- Tree felling and landscape proposals under development
Why is the Project Required?
The existing transformers were installed between 1995-1998 when engineering standards were very different. Modern transformers are quieter and more efficient but also require more space around them for cooling and safe access for maintenance teams. This, together with the need to keep the power station connected to the network, means that a new substation site out with the existing substation compound needs to be found in proximity to the power station.
Community Engagement
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 proposal 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.
How we’re embracing artificial intelligence (AI)
We intend to use AI to assist our experienced teams in the analysis of your feedback, so we can categorise key points raised more quickly. You can learn more about how we’re utilising AI on this dedicated web page.

Pre Application Consultation event
Pre Application Consultation Event
SSEN Transmission would like to thank members of the public that took the time to attend our pre-application consultation event. During this event, SSEN Transmission were consulting th public stakeholders on the emerging design for a new substation and associated works, to replace an ageing substation at the rear of the Sloy Hydro Power Station.
This event was held at the following location and date:
Three Villages Hall, Shore Road, Arrochar, G83 7AB
Tuesday 6th June,
1.30pm – 6.30pm
This was an open door drop-in session, and allowed for feedback to be given to the project team on our proposals. The consultation event allowed for presentation of key project information and plans, as well as providing the opportunity for public stakeholders to ask questions directly to the project team.
If you have any questions relating to this consultation please dont hesistate to get in touch with the project Community Liaison Manager - Caitlin.quinn@sse.com -

Proposal of Application Notice
We have now submitted the Proposal of Application Notice (PAN) to Loch Lomond & The Trossachs National Park Authority under the terms of the Town and Country Planning (Development Management Procedure)(Scotland) Regulations 2013. This notice states our intent to submit a planning application to replace the four transformers to the rear of Sloy power station to a new substation sited on land south of Sloy Power Station, Arrochar, G83 7DP. -
Feedback Period Closed
The feedback period for providing comments following our virtual consultation which was held on 24th August on our proposed Sloy Power Station Transformer Replacement project is now closed. The project team would like to extend thanks to all members of the public and stakeholders who took the time to provide feedback on our proposals. All responses received will now be reviewed by the project team and there will be further consultation at a later date. -
Feedback Period Open
The project team would like to thank members of the public and interested parties who took the time to visit our online virtual exhibition on the 24th June 2021. We hope you found it informative and beneficial. The feedback period for comments and feedback on these proposals is open until Tuesday 14th September 202. -
Virtual Consultation Exhibition - August
SSEN Transmission are holding a virtual consultation exhibition to hear views and gather feedback on our project proposals to replace four transformers and associated equipment at Sloy Power Station. This is being held on Tuesday 24th August 2021 and further details will be available on the website nearer to this date.
