Scottish Hydro Electric Transmission (SHE Transmission) has announced a public consultation to give residents details of its revised proposals on the Western Isles High Voltage Direct Current (HVDC) Link and HVDC Converter Station.

The Western Isles Transmission Link , which is required to enable the export of generated energy to the Scottish mainland, comprises a subsea electricity cable between the Scottish mainland and Lewis; a converter station on the mainland at Beauly and a converter station on Lewis.

SHE Transmission has revised its proposals for the route of the subsea cable and the site of the proposed converter station in Lewis. This had previously been proposed for location at Gravir and is now being suggested for siting at Arnish Point near Stornoway.

SHE Transmission’s project team will discuss the latest proposals and will be available to answer questions relating to the project at the event which will be held in the Garry Room of the Caladh Inn on James Street, Stornoway on Wednesday 21 October 2015 from 1:00pm to 7:30pm.

SHE Transmission Project Director Peter McKessick said:

“Following a review of our original proposals we want to update people about some planned changes to the Western Isles Link. The changes involve a change in the route of the subsea cable and a proposed new location of the HVDC converter station which was previously planned for Gravir but we are now proposing to locate at Arnish Point Stornoway.

“There are a number of benefits to siting the converter station at Arnish including the decommissioning of the existing Stornoway substation and the potential to allow a reduction of the existing wirescape near Stornoway. In addition, it could allow us to upgrade the overhead line circuit which runs down to Harris with and uprated line, parts of which could be placed underground.

“We would ask anyone who wants to find out more about our revised proposals to come along to the event on 21 October and meet our team, as the feedback we get from members of the public and statutory authorities is important and will inform how we progress our proposals and developments.”

All consultation materials will be published on the dedicated website – Comments on the process can be submitted in writing until 20 November 2015 to Neil Anderson, SHE Transmission, Inveralmond House, 200 Dunkeld Road, Perth, PH1 3AQ or by email to
