North South 400 kV Interconnection Development

This project proposes the addition of a new 400 kV overhead line to our grid, connecting the electricity grids of Ireland and Northern Ireland. This proposed line would run through counties Monaghan, Cavan and Meath in Ireland, and Armagh and Tyrone in Northern Ireland.

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

Meetings can also be arranged in Navan on request.
