Name and Location
Caithness high-voltage, direct-current (HVDC) power transmission link project, Scotland.
Client
Scottish Hydro Electric (SHE) Transmission.
Project Description
SHE Transmission is undertaking a major strengthening of its power network serving the north of Scotland to accommodate the rapid growth in electricity generation from renewable sources.
The Caithness-Moray 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 of electricity, equivalent to the electricity needs of about two-million Scottish people.
The link will strengthen the existing grid and enable the region to harness the large roll-out of offshore wind farms and other renewable-energy projects in nearby Scottish waters.
Value
Not stated.
Duration
The link is scheduled to become operational in 2018.
