BC Hydro says it should have Prince Rupert re-connected to the main electrical grid by 4 pm Thursday afternoon.
The city has been relying on the Rupert gas plant for power since landslides struck a number of electrical towers a week and half ago.
Community Relations Coordinator Dave Mosure says the switch has caused a few minor issues with some clocks.
Mosure says repairs were made difficult by the remote location of the damaged towers.
Mosure says the utility appreciates the patience shown by Prince Rupert customers.
