North-South Interconnector: EirGrid

Mr. Fintan Slye:
In order to enlarge the capacity, we are talking about doubling it. At that capacity, there are no installations worldwide of that size and we would need twice the infrastructure. Instead of one cable set in the road, we would need two cable sets in the road. We would only need one road opening or one trench through agricultural land, but the cost savings from a single mobilisation are far outweighed by the fact we need additional converter stations at each end. A converter station costs somewhere between €75 million and €100 million and additional cable sets. Cables cost in excess of €1 million per kilometre. The costs are not marginal, but potentially double.
