Decision needed on the North-South interconnector

IBEC has welcomed the recent publication of the Expert Commission Review in relation to the Meath-Tyrone (North-South) 400 kV Interconnection Project.

This vital infrastructure project is urgently needed to help Ireland to meet its legally-binding targets on renewable energy while also maintaining a secure supply of electricity.

The Commission’s report broadly confirms the findings of earlier studies - namely, that overhead AC lines represent by far the most cost effective option for this particular project. The best alternative option, using underground DC cables, would be at least three times more expensive to construct and might well also result in a higher risk of electricity network breakdowns.

Erik O’Donovan of IBEC’s Energy and Environment Policy Unit said - “A North-South interconnector is vital for the future electricity needs of the island of Ireland. The Meath-Tyrone project will benefit domestic and commercial electricity customers - not only by enhancing energy security, but also by enabling more efficient power generation, thereby keeping down costs.

"An unnecessary additional capital spend of €333 million is unwarranted, particularly in the current economic context. It would also set an unwelcome precedent that could hamper the continued roll-out of grid infrastructure to support further investment in clean energy over the coming decade.“

Mr O’Donovan added - “The Government needs to make an early decision to proceed on this aspect of the project. We would also encourage it to develop national planning guidelines on the development of other critical infrastructure projects of this type.”
