Some 59,000 homes, farms and businesses are without power on Wednesday morning as a result of damaging winds from Storm Barra.
Counties along the western seaboard from Donegal to Kerry have been most affected.
The ESB has said while poor weather conditions may hamper repair in some areas, ESB Networks will be doing everything it can to restore power to the majority of these customers by the end of Wednesday.
However, it warned that some customers may potentially be without power into Thursday.
ESB is asking the public to report any fallen wires to them on 1800 372 999.
There has been no major damage reported on Irish farms. However, some roofs have blown off sheds in parts of the country and fallen trees are blocking roads.
