Around 528,000 homes, farms and businesses across the country are still without power this morning.
ESB Networks crews have been out since first light to continue repair works and the Network have contacted British and French utilities for help.
If you come across fallen wires or damaged electricity network, never, ever touch or approach these as they are LIVE and extremely dangerous.
Please report any damage to electricity infrastructure by calling 1800 372 999.
