New underground electricity cable routes for Dublin revealed

January 30, 2024

Three major cross-city construction projects to begin this year, one of which is due to run through land at Leopardstown racecourse.

The first three routes selected for the replacement of underground electricity cables across Dublin, under a city-wide construction programme expected to take up to five years, have been revealed by EirGrid.

The operator is embarking on a major upgrade of the capital’s electricity grid, replacing 50km of underground cabling – some of which is up to 50 years old – on routes linking substations at Carrickmines and Poolbeg; North Wall and Poolbeg; Finglas and North Wall; with two routes required to link Inchicore and Poolbeg.

EirGrid last March published 12 route options for the cables, and following public consultation has chosen the final routes for the first three lines, with the two Inchicore routes due to be announced in the coming months. The work is due to start at the end of this year and be completed by 2029.
