Bids invited for Ireland-UK undersea Greenlink interconnector

WCN Editorial Team 27 Aug 2018 EUROPE ENERGY & UTILITIES

Greenlink Interconnector, Ireland, will construct a 205km undersea electricity interconnector between the UK and Ireland and has invited bids from companies to tender for the project.

One of the important infrastructure projects in Europe, Greenlink is a privately-financed Project of Common Interest (PCI).

A PCI is a project selected by the European Commission that will have a major impact on energy markets and market integration in EU countries; promote competition and help the EU’s energy security by diversifying sources; and contribute to the EU’s climate and energy goals by integrating renewables.

The EU recognised Greenlink as a PCI following support from the Irish and UK governments. It has also received funding from the EC through the Connecting Europe Facility. The EC has re-confirmed the Greenlink project as a PCI in November 2017.

Greenlink is a proposed 500MW, 205km subsea and underground high-voltage direct current (HVDC) interconnector, with associated converter stations, between the existing electricity grid operated by EirGrid in Ireland and the electricity grid operated by the National Grid Electricity Transmission in the UK.

Irish company Greenlink Interconnector, a subsidiary of Element Power, is developing the Greenlink.

The project will link the Great Island transmission substation in County Wexford of Ireland and Pembroke transmission substation in Pembrokeshire, Wales.

Construction is due to commence in 2020 and is expected to begin operations in 2023.

The company has published a Contract Notice in the Official Journal of the European Union (OJEU) to begin procurement of the EPC contracts for the construction of the project.

Onshore, the cable will run for a length of 28km (underground) in Ireland and 6.7km (underground) in Wales. Offshore, the cable will run for an approximate length of 160km (subsea).

WSP is running the procurement process on behalf of Greenlink Interconnector.

Interested applicants should submit the completed application forms on or before 12 October 2018.

Greenlink project director Simon Ludlam said: “This is a major milestone for the project and follows our recent market consultation with the supply chain over the summer.

“We will run a competitive tender to drive down costs and ensure maximum benefit for consumers. In parallel we are running our subsea surveys that will determine the optimal cable route across the Irish Sea to inform the procurement process.

“Greenlink is looking forward to a constructive dialogue with suppliers over the next year to select its preferred bidders and move to the award of contracts for the construction phase in 2020.”
