ESB repair crews are working since early Friday morning to restore power to an about 1,500 customers who were without power overnight after Storm Doris swept across the country.
However, an ESB spokesman has confirmed “small pockets” of customers will remain without power for a second
At one stage on Thursday up to 56,000 homes were without power as powerful winds resulted in more than 900 individual faults across the network.
An ESB spokesman said on Friday crews had been out trying to fix the 600 faults remaining.
“The vast majority will be restored by tonight but there will be small pockets without power for a second night,” he said.
He said the areas still without power stretched from counties Mayo, Sligo, Louth, Roscommon, Leitrim, Longford and Cavan.
ESB's head of corporate communications Bernadine Maloney said the volume of faults and the nature of the terrain meant the process of restoring power was a "hard slog" for the estimated 2,000 technicians working on repairing the faults.
Householders experiencing a power cut were told to see if their fault was already logged on the powercheck.ie website, and if not, to telephone 1850 372 999.
