Greenwire will connect separate wind farms in the Midlands of Ireland to a regional collector node to harness their combined energy in a single output. The project will create 3,000 megawatts of generation capacity from a single point.
The energy captured will then be transferred by underground cabling to the Irish east coast and via two purpose built subsea cables to the United Kingdom. On reaching either of the two landing points in Wales, the electricity will be fed into the UK national grid and distributed to major load centres and cities for consumption.
The design proposed by National Grid will see a HVDC (High voltage, direct current) cable leading from Pentir near Caernarfon in north Wales to a central collection point in the Midlands. A second cable will lead from the same point to Pembroke in west Wales. Both cables will be around 150mm in diameter, and be rated at 2,500 megawatt.
