DAA Solar Farm Grid Route

In 2024, Mainline completed the medium-voltage (MV) cable grid route from Dardistown Substation to the solar farm located adjacent to Dublin Airport. The project involved the installation, testing, and commissioning of over 30 km of 400mm² MV cable, nine joint bays with associated pit furniture, and three substation terminations (two in the solar park and one at Dardistown).

A significant portion of the route was constructed within the active airfield environment, requiring stringent safety and operational coordination. Extensive ITP documentation was submitted through the DAA’s ACC portal. The project was delivered on time and in line with all quality expectations.
