  • Caithness HVDC switching station

    To enable a proposed subsea transmission cable from Shetland to connect to the network, we are proposing to construct an HVDC switching station north of Wick in Caithness.

  • About the Caithness HVDC switching station project

    As part of its role, SHE Transmission is required to develop proposals to accommodate new sources of electricity generation seeking to connect to its network. In response to generators seeking to connect in Shetland, we are proposing to install a new High Voltage Direct Current (HVDC) transmission cable which would connect the islands to the Great Britain electricity system for the first time. HVDC technology makes it possible to transmit electricity efficiently across the distances involved in connecting Shetland, which is located about 170 kilometres north of mainland Scotland. 

    SHE Transmission has developed a proposal to provide a connection by connecting to the HVDC system that is currently being installed between Caithness and Moray. This arrangement makes use of capacity available in the Caithness-Moray subsea cable to allow onward connection to the existing onshore transmission network in Moray with minimum new infrastructure. 

    To connect with the Caithness-Moray system, a switching station is required in the vicinity of the planned cable landfall which is north of the village of Staxigoe in Caithness. The switching station would allow the flow of electricity to be managed between 3 underground HVDC circuits - one from a converter station at Spittal in Caithness, one from a converter station at Kergord in Shetland and one to a converter station at Blackhillock in Moray.

    Public consultation

    Two public consultation events will be held to display the preferred project options ahead of a planning submission to The Highland Council in September 2016

    The project development team will be hosting two open door consultation events to present our preferred options for the proposed HVDC Switching Station location and building design. Members of the public are encouraged to attend at any time to view our proposal, events will be held at:

    • Wick Assembly Rooms, Monday 27 June 1430 - 1930 
    • Staxigoe Hall, Tuesday 28 March 1430 - 1930

    Feedback submitted to SHE Transmission as part of the pre-application consultation process is not part of the statutory consultation which will be carried out by the consenting authorities. Once an application for consent has been submitted, there will be an opportunity to make formal representations to the Highland Council before it takes a decision.
