At least 10,000 households are without power and flights have been cancelled as a result of Storm Hannah, which arrived in the south west from the Atlantic this evening.
ESB Networks says the areas most affected include the Iveragh and Dingle peninsulas and areas of west Cork including Macroom.
The damage is mainly due to trees falling on overhead lines.
ESB Networks repair crews are being dispatched to the affected areas.
It is expected that as the storm continues to track across the country, further outages are likely.

Local councils prepare for Storm Hannah
Carmel Kirby, director of services at Clare County Council, is urging people to tie up any loose belongings ahead of expected high winds.
Ms Kirby said the local authority's teams would only be able to respond to "very severe incidents" this evening, and urged people to stay inside their homes until the worst of the winds had passed.
Senior Engineer at Cork County Council, Aidan Weir, said the public was being advised to stay away from the coast, particularly in the southwest.
He said: "We're advising motorists to take caution and we will have crews and contractors on standby to deal with fallen trees."
Mr Weir added that there was no concern for flooding of the River Lee as "conditions for tide and surge are favourable".
Meanwhile, Kerry County Council has set up a helpline for those affected by Storm Hannah. The number is 066-7183588.
