About the project 

Due to the projected increase in renewable energy generation in Argyll, a need has been identified for the upgrade and reinforcement of the electricity transmission network on the Argyll peninsula to ensure supply and support the transition to net zero emissions. 

As described during the development process for the Inveraray – Crossaig overhead line rebuild, the replacement overhead line is being built at a higher 275 kV voltage, initially operating at 132 kV between Inveraray and Crossaig.

As future renewable generation connects to the electricity network and the operating voltage is required to increase to 275 kV, substations along the route will also require to be replaced in order to accommodate this voltage increase.

We are therefore proposing to construct and operate four (4) new 275 kV electricity substations at the following locations: 

• in the vicinity of the existing An Suidhe substation;
• in the vicinity of the existing Crarae substation;
• in the vicinity of Craig Murrail, north of Lochgilphead; and
• in the vicinity of the existing Crossaig substation. 

Once the 275kV Substations are constructed, the existing 132kV An Suidhe, Crarae and Crossaig substations will be decommissioned.

As part of our Winter 2021 project consultation we held a webinar on 14th December 2021,  inviting statutory consultees, community council members and local elected members to discuss our proposals ahead of our planning application process. Please see a recording of the webinar adjacent for more information.
