NB Power says the aftermath of Arthur is the worst event for outages in the history of the provincial utility.
At the peak, about 140,000 customers were left in the dark in New Brunswick and the majority of those were in the Fredericton region.
Officials in the provincial capital estimate more than 2,000 trees either came down or were damaged during the storm and that has created havoc for power crews.
A spokesperson for NB Power anticipates that 80 percent of customers will have electricity back by Wednesday.
In the meantime, a number of public buildings have been turned into recharging stations for medical devices, mobile phones and tablets/laptop computers.
UPDATE – Eight days after Arthur, NB Power is still reporting about 4,000 outages, mostly in Greater Fredericton, due to a tangled mess of downed trees and power lines.
