SSEN Transmission has announced an extension of the feedback period for its proposed new HVDC converter station and AC substation on Arnish Moor. Recognising the significant local interest and engagement in the project, the company has extended the consultation deadline to Thursday, November 28th.

The proposed Western Isles HVDC link is a key component of Scotland's transition to net zero emissions. The project will enable the connection of 1.8GW of new renewable energy generation to the electricity transmission network.

A second consultation event is scheduled for November, where SSEN Transmission staff will be available to answer questions and provide detailed information about the proposed site location, layout, visualisations, and connections.


The Lewis Hub, comprising a 400kV substation and converter station, is a crucial element of the Western Isles HVDC link. This project is expected to play a vital role in supporting the region's renewable energy development and contributing to Scotland's broader decarbonisation goals.

Kevin Morrison, Community Liaison Manager with SSEN Transmission, said: "We recognise the strong local interest and level of engagement in our proposals, and that is why we have extended the feedback period for our first statutory pre-application consultation until November 28, to allow more opportunity for people to have their say.

"We intend to hold a second consultation event in November and will provide further details on this to the public in due course.

"In the meantime, we encourage anyone who hasn’t yet had the chance to submit their feedback to do so, as this is a key part of our project development process. We’d also encourage people to keep informed by signing up for project updates on our website."
