A judicial review at the High Court in Belfast has upheld Planning Approvals for the North-South Interconnector project.
SONI, the electricity transmission system operator for Northern Ireland, has welcomed the decision and says it will "continue our engagement with landowners and communities".
SONI added that the "North-South Interconnector will be a key enabler for economic growth as part of a green recovery" and is "one of the key safeguards Northern Ireland needs to provide long term security of supply".
At a meeting with Monaghan County Council in April, EirGrid's chief infrastructure officer, Michael Mahon, said the company would seek to assign contractors following the outcome of the judicial review, following which they would approach landowners.
Meanwhile, at the most recent meeting of the Local Authority, councillors passed a motion of no confidence in EirGrid over its handling of the North-South Interconnector.
