Northern Ireland Electricity (NIE) has released video footage of its emergency teams struggling in deep snow to restore power to thousands of homes.
"NIE emergency crews worked round the clock since Friday morning responding to network faults caused by prolonged blizzards", the electricity company said.
The firm thanked its customers for "all your patience" during its power restoration efforts over the weekend.
Over 140,000 customers have been affected by the severe weather since it began Thursday night, and around 50 properties remain without power, NIE added.
The wintry conditions are now expected to last well into April with this month on track to become the coldest March since 1962.
A group of students from Wolverhampton who were stranded in extreme snow in Scotland for more than three days tell their story of survival.
Cold weather can pose a real health risk to older and disabled people, but everyone can gain from preparing their homes for the cold.
