Greenlink has appointed WSP to its €400M (£353M) electricity interconnector linking Wales and Ireland.
The 500MW 200km high voltage direct current (HVDC) link is being developed by Greenlink Interconnector and will include 205km of underground and submarine cable.
Greenlink includes of a converter station at each end, connected by two electricity cables and a fibre optic cable. The cables will run underground and under the sea from the Great Island substation in County Wexford to Freshwater West beach in Wales, before continuing to run underground to the Pembroke substation.
WSP will support Greenlink through the final cost and technical assessments for Ofgem and CRU and will run the procurement process for the HVDC system, including the underground and submarine cable.
Greenlink project director Simon Ludlam said: “Greenlink represents significant inward investment at a local level on both sides of the Irish Sea, as well as supporting the UK and Ireland’s national energy security and low carbon strategies. In awarding this contract to WSP we are pleased to be able to draw on their experience and expertise as we continue to progress the development of the project.”
Construction is due to start in 2020.
The project is predicted to save Irish consumers around £705M (€800M) over its lifetime, whilst also improving Great Britain’s access to Ireland’s significant renewable energy generation and increasing security of supply for both countries.
