Newfoundland and Labrador Hydro's Sunnyside terminal station caught fire causing the Holyrood Generating Station to shut down.
Newfoundland Power on Twitter said that about 125,000 customers are affected and full restoration may not happen until Sunday.

The blackout comes as much of Atlantic Canada spent Saturday cleaning up after a powerful blizzard which is blamed for cancelled flights and dangerous driving conditions.
The weather system whipped through the Maritimes Friday before passing southeast of Newfoundland's Avalon Peninsula overnight.
