Power outages in north Dublin, Offaly, Waterford and Mayo - but most significant fault not caused by weather
Up to 1,000 homes and businesses are without electricity this morning.
The ESB is reporting power outages in Malahide and Fairview in north Dublin, in Bannagher, Co Offaly, in Kilmeaden, Co Waterford and in Westport, Co Mayo.
700 of those affected are in Malahide, where there was a single tripping fault.
The ESB says the issue was probably not caused by rain last night.
Service should be restored to homes in Dublin this morning, and in other parts of the country by the afternoon.
