Almost 500 homes and businesses remain without power this Monday morning after Storm Atiyah.
Faults are reported in Leghowney outside Donegal Town and in Annagry in the West Donegal Gaeltacht.
Many more properties around Donegal were affected by power outages on Sunday afternoon as high winds struck. South Donegal was one of the worst affected areas, with power being restored to the majority of homes by the evening.
Up to 385 properties in Annagry and Loughanure remain without electricity this morning after a power cut shortly before 11pm.
ESB is currently working on repairs and estimate that supplies will be restored by 2pm near Loughanure and 3pm in Annagry.
Meanwhile, 48 properties have no power in Leghowney outside Donegal. Power was lost before 2pm on Sunday and it is expected that supplies will be repaired by 1.52pm today.
ESB Networks is urging the public not to approach fallen wires, as they may be live and dangerous.
