Greenlink is a proposed HVDC submarine power cable between County Wexford in Ireland and Pembrokeshire in Wales.
Project status[]
in April 2020, the company submitted three planning applications for onshore construction in Wales.[2] The project still requires planning permission and marine licences in both the United Kingdom and in Ireland, but the process of procuring construction contracts has started. Construction is planned to begin in the second half of 2020 and will take about three years. [3][4]
Route[]
The cable is proposed to run between EirGrid's Great Island substation in County Wexford, and National Grid's Pembroke substation in Pembrokeshire, with the cable making landfall at near Fethard-on-Sea in Ireland and at Freshwater West beach near Castlemartin in Wales. The total length would be 200 km (120 miles), of which 160 km (100 miles) would be under the sea.[4][1][5]
Specification[]
The HVDC link will be configured as a symmetrical monopole, with DC voltages of ±320 kV, and nominal power rating of 500 MW. The project is expected to cost €400 million.[1]
Project history[]
Subsea surveys were undertaken in 2018, and public consultations in 2019.[4]
In March 2021, the project was granted a licence to install the sea cable in UK waters, with a similar licence for Irish waters still pending. As of March 2021, commissioning of the interconnector is planned for the end of 2023.[6]
