The ESB has said fewer than 2,000 homes are now without power after adverse weather conditions last night and this morning.
Earlier up to 5,000 homes and businesses were affected by outages due to storm damage.
Around half of the outages were in Enniscorthy, Co Wexford.
A quarter of the outages were in Bandon, Co Cork, while the remainder were in small patches around the country.
ESB crews are working to restore full power to those affected.
