HVDC Hub project
The Offshore HVDC Hub project was
undertaken by Scottish Hydro Electric Transmission plc (SHE Transmission), with
co-funding from the European Union under the European Energy Programme for
SHE Transmission ran a Knowledge Sharing seminar in Glasgow on 20th
July 2015 to share key project outputs. A project overview paper and material
from the seminar are available at the links below.
The EU capital grant allocation in 2009 was intended to support the inclusion of an offshore HVDC hub in the route of a subsea HVDC link already in planning by SHE Transmission and which would run close to the sites of potential future offshore wind farms in the Moray Firth, northeast Scotland. The hub was intended to facilitate an economic transmission solution for the area, including offshore windfarm connections, and provide a supply-chain opportunity for deployment of offshore multi-terminal HVDC technology.
As at July 2015, SHE Transmission has an important Caithness to Moray subsea HVDC link under construction through the Moray Firth to accommodate the export of onshore renewable energy from Caithness. However, prevailing circumstances in 2012 meant that when the link design was to be finalised it was done so without the offshore HVDC hub being included. Nevertheless, the pre-construction work co-funded by the EU has delivered several outputs of value to the future development of offshore grids:
2-3 Multiterminal specification issues
2-4 National HVDC centre presentation
hub FEED output presentation
Hub seminar event
Moray Firth HVDC hub presentation
