The largest investment in north Scotland’s electricity network since the hydro development era of the 1950s. SHE Transmission is undertaking a major strengthening of its power network serving the north of Scotland to accommodate the rapid growth in generation of electricity from renewable sources. The Caithness Moray HVDC Link enables a future with more renewable power feeded into the Scottish grid.
The subsea link will connect the electricity grid on either side of the Moray Firth in Northern Scotland using HVDC Light technology. It has the capacity to carry up to 1,200 MW (megawatt) of electricity, equivalent to the electricity needs of about 2,000,000 Scottish people.
As part of the project, ABB will design, engineer, supply and commission two landbased 320 kV HVDC Light converter stations, one rated 1,200 MW at Blackhillock in Moray and another rated 800 MW situated at Spital in Caithness. ABB’s scope of supply also includes submarine and underground cables covering a total transmission length of nearly 160 kilometers.
Furthermore, the link benefits from a five year service agreement, which includes 24/7 phone support, training, remote access, grounds maintenance, spare parts and facility management, and preventive and corrective maintenance.
