SSE’s Caithness-Moray project is upgrading the electricity transmission system in the north of Scotland unlocking 1200MW of renewable generation across the north of Scotland. It will use High Voltage Direct Current technology to transmit electricity between Caithness and Moray. At £1.1bn the project represents the single biggest investment SSE has ever made, allowing more renewable power from the north, to connect more efficiently with the south of Scotland.
- Unlocks 1200MW of renewable generation from across the north of Scotland
- £1.1bn project, largest ever single investment undertaken by SSE Group
- First HVDC system solely in Scotland
- Over 6 million hours worked
- Largest substation in UK, equivalent to 24 football pitches
- Due for completion end of 2018
- The Caithness-Moray submarine cablewill use High Voltage Direct Current (HVDC) technology to transmit power beneath the seabed between converter stations at Spittal in Caithness and Blackhillock in Moray.
- The subsea cable, can carry up to 1,200MW of electricity between Caithness and Moray. With associated reinforcement of the existing onshore network, the project represents the largest investment in the North of Scotland's electricity network since the hydro development era of the 1950s.
