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. Also known in Northern Ireland as the Tyrone to Cavan Interconnector. If approved the 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.

The Planning Appeals Commission held a Public Inquiry into our planning applications for the project at the Armagh City Hotel. During the Public Inquiry the Commissioner set an indicative timeline for a recommendation by the end of the year.
The Planning Appeals Commission held ‘Stage 1’ of its Public Inquiry in June 2016. This hearing looked at procedural and legal aspects of SONI’s planning applications.
SONI is hopeful that a planning decision will be announced in Q4 2017. Estimated construction time for the North South Interconnector Project remains approximately 3 years from the date of planning consent. Therefore based on the timelines outlined, we anticipate that it would be operational by Q4 2020.
