Scottish and Southern Electricity Networks Transmission (SSEN Transmission), the wholly-owned subsidiary of SSE, has completed the construction, commissioning and energisation of the new Caithness-Moray electricity transmission link.
The link uses HVDC (High Voltage Direct Current) technology to transmit power through a 113km subsea cable beneath the Moray Firth seabed between new converter stations at Spittal in Caithness and Blackhillock in Moray. Constructed over a period of four years, the project also involved work at eight electricity substation sites and has also required two overhead electricity line reinforcement projects. The Caithness-Moray link provides up to 1,200MW of capacity to transmit power from the increasing sources of renewable energy from across the far north of Scotland. The link has already enabled turbines from Beatrice offshore wind farm (588MW on completion) and Dorenell onshore wind farm (177MW on completion) to connect to the national grid with a further 100MW of onshore generation in Caithness and Ross-shire due to connect in the coming months.
