Northern Ireland Electricity (NIE) Networks said its more than 1,550 staff and contractors have been “tirelessly” working to restore power, though some areas may not see electricity return until 10pm on Saturday.
In a statement on its website, NIE Networks said: “We continue to work tirelessly to restore power to all those still affected across Northern Ireland.
Ms Garrett said she has spent hundreds on hotel rooms for herself, her two sons aged 11 and 14, and her mother-in-law and father-in-law – while her husband has remained at home, without lights and heating, to keep the property safe.
Efforts to repair damaged power lines continue into a seventh day as thousands of homes across Northern Ireland are still waiting for their electricity supplies to be restored.
Ms Garrett estimates she has spent more than £1,500 to cover the cost of three nights at their local hotel, food waste and other daily food purchases.
