Years of roadwork ahead for Dublin’s electrical upgrade

Dubliners will face a “considerable amount of roadwork” for several years when a project to lay up to 50km of underground power cables gets underway by 2024.

Electricity operator EirGrid plans to embark on a major multi-year upgrade of the capital’s power grid, which will see the replacement of underground wiring, some of which is up to 50 years old.

Technical studies have identified the need to replace the cables linking the substations at North Wall and Poolbeg; Finglas and North Wall; Poolbeg and Carrickmines; and two cables linking Inchicore and Poolbeg.

A new connection linking Carrickmines and Inchicore is also required, along with a possible requirement for cables to feed potential new substations to the north and west of the city.

EirGrid chief executive Mark Foley said the work is necessary to meet renewable energy targets and growing energy demand in the capital.

“EirGrid needs to meet Dublin’s growing and changing electricity needs. This includes the electrification of transportation systems, vehicles, heating, and the development of housing, offices, and large energy users,” he said.

“We also need to accommodate new, clean sources of electricity, such as wind, to help Ireland transition to a low-carbon future.”


In an effort to minimize disruption, the “Dublin Infrastructure Forum” has been established involving a number of organizations including ESB Networks, Gas Networks Ireland, Irish Water and Dublin Bus. However, Foley said the work would inevitably affect to residents and businesses.

“We are now looking at options on how we can do this and what areas may be affected. We know that there will be a considerable amount of roadwork required to complete the works. We also understand that electrical infrastructure projects like these affect local residents and businesses.”

EirGrid will be holding a series of webinars for the general public, community, and business community in the coming weeks. From these, a community forum and a business forum will be established.

“We will give back to the communities as part of our community benefit policy while the works are being carried out. Our support will focus on community, sustainability and biodiversity issues,” said Mr. Foley.

The webinars will be held on May 31 at 7 pm for the general public, June 1 at 12:30 pm for businesses, and June 2 at 7 pm for community organizations. Details will be available in advance at
