Between November 2011 and December 2013, additional HVDC cable route surveys were carried out for the Western Isles transmission reinforcement, alongside a tender revalidation process, resulting in revised cost estimates of around £750 million for the link. These further route investigations, which revealed changes in soil resistivity on the onshore portion of the cable, contributed to significant cost increases passed through to Western Isles generators under the prevailing transmission charging methodology.
