The Storm force winds associated with Storm Franklin overnight have caused damage to the electricity network, and currently 18,000 homes, farms and businesses remain without power, predominantly in the Northwest.
The EBB say crews have made progress in restoring supply to approximately 11,000 homes, farms and businesses.
The damage, mainly due to fallen trees on overhead lines as a result of the high winds, has been most extensive in counties Donegal, Sligo and Leitrim.
Most impacted areas include Milford, Ballyshannon, Donegal Town, Buncrana, Manorhamilton and Arigna.
ESB Networks is currently moving additional resources into the Northwest, including crews who were assisting in repairing damage in South Kerry, West Cork and South Wexford in the aftermath of Storm Eunice on Friday.
These crews will work through this afternoon into this evening to restore as many customers without power as possible.
The ESB are advising that if you come across fallen wires or damaged electricity network, never, ever touch or approach these as they are LIVE and extremely dangerous. Please report any damage to electricity infrastructure by calling 1800 372 999.
