North South Interconnector

This project proposes the addition of a new 400 kV overhead line to our grid, connecting the electricity grids of Northern Ireland and the Republic of Ireland. It is also known in Northern Ireland as the Tyrone to Cavan Interconnector. When built, the project will start at a substation in Turleenan, Co Tyrone. It will then run into Co Armagh and then into counties Monaghan, Cavan and Meath.

If you would like more information on any aspect of the project, you can talk to our team on the ground.
