Overview
About the Project
SSEN Transmission has submitted a planning application for an Alternating Current Harmonic Filter adjacent to the consented and currently under construction Crossaig North 275/132 kV substation.
In simple terms, the filter is needed to help smooth out electrical disturbance on the network. Monitoring has shown higher than expected levels of harmonic distortion at Crossaig substation which can affect how efficiently and reliably equipment operates. The proposed filter is therefore needed to help keep the electricity system running safely and reliably.
The application is for a new 132kV AC Harmonic Filter and associated works, including earthworks, temporary access, drainage, fencing and landscaping, on land to the west of the Crossaig North substation.
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.
