There's been a massive drop in the number of buildings across Dublin without power.
Teams have been working through the night and will continue to work until all faults are fixed.
Operations manager Derek Hynes says "our bigger concern is the safety of our staff and then the safety of other members of the public."
"We have been working through the night, and will continue to work to try and have everyone's power restored hopefully by this evening", he said.
