What onshore work is required?

The onshore construction works will comprise of a landfall and Transition Joint Bay (TJB) site(s), the laying of cables, and the construction of an onshore substation(s), adjacent to Carrickmines, Poolbeg or any other connection point as agreed by Eirgrid.

The onshore cable routes to get to the substation will be chosen based on a number of factors, with the goal being to reduce the cable installation nuisance as much as possible.

All sites related to the works required at the landfall and along the cable route will be restored to their original condition following the completion of the works.

The only onshore works that will be visible after completion will be the onshore substation. There are ongoing works to find the best location for this substation, subject to the constraints of the existing electricity grid system in Dublin. The two main sites currently being investigated are at Carrickmines and Poolbeg. The substation will be located as close as possible to existing ESB structures.
