Finglas – Dublin Airport 220kV power line

EirGrid is building an electricity link called the East-West Interconnector between the electricity grids of Ireland and Britain. The Interconnector will help to ensure Ireland always has enough electricity to meet your needs into the future. It can also be used to export any excess energy that is produced here to markets in Britain.

The Project involves the laying of a 400kV electricity cable between Shotton and Barkby Beach, North Wales, across the Irish Sea, and between Rush North Beach, Co. Dublin and Woodlands, Co. Meath, Ireland.Richard Nolan Civil Engineering are involved in the installation of 20 km’s of ducting overland between Ashbourne Co. Meath and the convertor station at Woodlands and involves the laying of 2no. 200mm ducts at 250mm centres, to carry the cable, and a smaller duct in which a fibre optic cable shall be placed. The project requires significant traffic management and an extremely high standard of Health and Safety and Quality.
