There are approximately 101,000 customers without electricity following the devastation caused to the electricity network by Storm Eowyn.
A yellow weather warning for wind is in place across Northern Ireland on Sunday.
The warning will last from 10:00 to 19:00 GMT with many areas experiencing gusts up to 40-60 mph.
It comes two days after Storm Éowyn brought winds of more than 90mph to Northern Ireland.
"Given ongoing recovery work after Storm Éowyn, impacts may be more widespread than would ordinarily be expected with winds of this strength," the Met Office said.
The managing director of NIE Networks said power has now been restored to 183,000 properties.
