"Residents and business owners have been so patient, but this has been massively inconvenient for them," Eastland general manager Brent Stewart said.
"We wanted to not only make sure the power supply was secure, but also get it back up and running again as quickly as possible.
"Today's conditions have been ideal for installing the new conductors next to the live ones, which is the tricky part of the process that required the power to be off."
Eastland had expected it would take until 2pm today to make the final repairs to the lines.
"On behalf of Eastland Network and the crews, I'd like to thank this very special community of ours, which has rallied round in challenging circumstances," Stewart said.
The company offered its condolences to Anderson and Solouota's families.
