In a statement, Duke Energy said a majority of customers are expected to have power returned no later than Friday evening, Oct. 4. However, repair efforts are so widespread that very few areas have been assigned estimated times of restoration.

There are lots of areas across the South Carolina Upstate and North Carolina mountains where we’re going to have to completely rebuild parts of our system, not just repair

Duke Energy expects to restore most of those remaining outages by Friday night, though some of the hardest hit regions are still inaccessible.
