235,000 homes, farms and businesses are without power this morning after Storm Isha brought down trees and power lines overnight.
ESB Networks is warning it could be a number of days before power is fully restored to all households.
Red and orange wind warnings are now over, but yellow alerts remain in place for counties Clare, Donegal, Leitrim, Galway, Mayo and Sligo until 7pm on Monday.
The strongest gust recorded overnight was 150 km/h in Clew Bay in Co Mayo.
Brian Tapley from the ESB, says hundreds of extra engineers have been contracted to help with the restoration efforts.
"This morning there'll be a big exercise in assessing damage and doing 'extreme danger' calls first, so any fallen conductors or anything that might be still live.
"When we assess the damage we'll also then begin fault restoration.
"We'll be bringing all available crews, we'll be mobilising them to where they're needed most, and we'll be utilising as many of our contracting partner crews as we have around the country."
