SDLP Opposition Infrastructure Spokesperson Mark H Durkan MLA has said the Executive must take steps to support those worst impacted by Storm Éowyn.
Around 65,000 homes remain without power and many roads are blocked by fallen trees and other debris.
NIE say it could be the start of February before all homes and businesses are reconnected.
Said the Foyle MLA: “While the majority of us are now lucky that power has been restored to our homes and local businesses, there are still a large number of people across the North living without electricity and attempting to pick up the pieces of the last few days.
“We have seen older people left living in cold homes with no power, while others have lost out as a result of their appliances shutting off.
“The Executive must ensure they are doing everything they can to support people, particularly those worst impacted by the storm.
“The clean-up from this unprecedented destruction will take some time, but the Executive should be considering every option open to them to restore power and ensure that those worst affected can be properly compensated for damage and other losses.
“There are still a number of trees at risk of falling in strong winds and public buildings, including our schools, in need of repair.
“During this process work should also be undertaken to safeguard these properties from similar damage in future.
“Given the worsening climate crisis this is unlikely to be the last time we see a weather event of this nature and we need to act now to ensure we are prepared when the next storm comes.
“I would like to pay tribute to all of Northern Ireland Electricity, Department for Infrastructure and other frontline workers who haven’t stopped over the last few days, working around the clock to restore power, fix damages and clear our roads with far fewer staff than needed for such an operation.
“We have also seen local communities step up and look after each other, whether it’s checking in on elderly neighbours or clearing local roads and paths. It’s heartening to see people pull together after such a turbulent few days.”
