Balallan Switching Station and 132kV OHL

About the Project

The development of onshore renewables on the Isle of Lewis, particularly wind power, has driven a requirement to reinforce the electricity transmission network on the island. Key benefits of these works will include the connection of local renewables, planned and future, onto the network as well as improving the security of the electricity network on Lewis.

To support the connection of the Uisenis Wind Farm, located to the south of Stornoway, the following works have been identified:

• The construction of approximately 25km of new 132kV overhead line (OHL) to replace the existing line linking Lewis and Harris
• The construction of a new Gas Insulated Switching Station near Balallan, to facilitate the connection of the Uisenis wind farm onto the electricity transmission network
• The removal of the existing 132kV OHL between Balallan and Stornoway Grid Supply Point
• Connections of the OHL at Balallan, Stornoway Grid Supply Point and the new Arnish substation

Why is the Project Required?

The works are required to meet the needs of renewable developers on Lewis looking to connect to the GB Transmission System, and form part of our proposed transmission link from the Western Isles to the Scottish mainland.

3D Visualisation of the Project 2018

In partnership with specialist company 3DW, we have created a video which allows stakeholders to visualise the new Balallan 132kV Switching Station and Balallan – Stornoway 132kV Overhead Line Replacement. It has been created to increase the transparency of our plans and was on display at the public exhibition held in Stornoway in 2018.

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.
