The ESB says it hopes to have the majority of the 8,000 homes still without power restored by this evening.
Counties Mayo, Sligo, Clare and Limerick are worst affected.
Schools are also reopening today in a number of counties, after being forced to close due to Storm Barra.
Speaking to Newstalk, Siobhan Wynne from ESB Networks says its crews are making good progress:
"The worse effected areas are still along the Western seaboard. Crews are mobilising this morning to attend the remaining faults.
"In addition to that we are now able to redeploy crews from less impacted areas to those worse affected."
She said they also have crews from Northern Ireland Electricity (NIE) helping out as they are looking to get the majority of homes back online by this evening.

In a press release released last night, ESB said: "Around 13,000 customers remain without supply, down from around 60,000 customers earlier this morning.
"While poor weather conditions have hampered repair works in some areas, ESB Networks’ crews will continue to work into the night doing everything they can to restore power to as many remaining customers as possible and crews will mobilise again at first light tomorrow.
"Following further strong winds last night and during today, counties along the western seaboard from Donegal to Kerry have been most impacted."
