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 Baginbun Beach near Fethard-on-Sea in Ireland and at Freshwater West beach near Castlemartin in Wales. The total length would be 200km, of which 160km would be under the sea.[4][1][5]
Specification
The HVDC link will be configured as a symmetrical monopole, with DC voltages of ±320kV, and nominal power rating of 500MW. The project is expected to cost €400M.[1]
Project history
Subsea surveys were undertaken in 2018, and public consultations in 2019.[4]
