An example of the type of cable that might form part of the interconnector Shetland is not currently linked to the UK electricity transmission network. To enable the electricity generated by the Viking Energy Wind Farm – and future renewables projects – to be exported, a subsea high-voltage direct current (HVDC) cable will be laid between the islands and Caithness.
The transmission cable is not the responsibility of Viking Energy but of grid operator Scottish & Southern Electricity Networks.
Without an interconnector, many smaller renewables projects proposed for Shetland may not be able to happen. These include tidal power farms and various community-owned wind turbine developments.
