Greenlink is a 190 km high-voltage direct current (HVDC) submarine power cable under construction between County Wexford in Ireland and Pembrokeshire in Wales. [3]
As of May 2022, the project has reached financial close, [4] and construction has started. [5]
Offshore construction was scheduled for 2022–23. Trial operation and commissioning is planned for 2024. [6] The link is expected to be in operation by mid-September 2024. [2]
The cable will 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 will be 200 km (120 miles), of which 160 km (100 miles) will be under the sea. [7] [1] [8]
The HVDC link is to 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]
Subsea surveys were undertaken in 2018, and public consultations in 2019. [7]
In April 2020, the company submitted three planning applications for onshore construction in Wales. [9] The project still required planning permission and marine licences in both the United Kingdom and in Ireland, but the process of procuring construction contracts had started. [10] [7]
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 [update], commissioning of the interconnector was planned for the end of 2023. [11]
In January 2022, construction work on converter stations started. [5]
In March 2022, the company announced that it had reached financial close. [4]
As of September 2022, work had started on the cable route from Great Island to Baginbun with completion of the project now expected in 2024. [12]
