Overview
This page brings together information on SSEN Transmission projects in the Crossaig area. These include:
The project will build a new 275kV substation and overhead line at Crossaig, upgrading the existing 132kV site and connecting to the Inveraray–Crossaig line. This will increase network capacity and support the export of renewable energy from the Argyll area.
High Constellation Wind Farm Connection
The project proposes a 3.9km 132kV underground cable to connect the 50MW High Constellation Wind Farm to the existing Crossaig Substation, enabling renewable energy export, subject to securing the required consents and wayleaves.
We have applied to install a 132kV AC harmonic filter at Crossaig North substation to reduce electrical disturbance and improve network reliability, along with associated infrastructure works.
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 proposals with local community councils, encourage engagement from the wider community and listen to the feedback we receive.
We will do our best to answer any questions and address issues or concerns that are raised with us.
When our project progresses into construction, we will continue working closely with the local community to ensure that our work has as little impact on the lives of those living and working in the area and as many long term positive effects as possible.

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.
