West Cork’s Bere island has been left without power for over 24 hours after an undersea electricity cable was damaged.
ESB Networks said a total of 281 customers remain affected by the power outage, which also affected the Castletownbere area of West Cork.
It said it was hoped to have all supplies restored late on Friday night as crews worked to identify the fault and make emergency repairs.
The power fault was reported at about 3.30pm on Thursday and affected some properties in Castletownbere and the entire island community on Bere.
While supplies were restored in Castletownbere, the ESB said it had to commission specialist divers to inspect the undersea cable.
It said it believed the damage was caused by a fishing vessel.
