Power outages are being reported across the Avalon and Bonavista Peninsulas this morning and as far west as Gander.
Newfoundland Power says loss of supply from NL Hydro is the cause of the outages and about 30,000 customers are without power.
The power outages affecting many areas of St. John's began around 7:20 a.m.
Locations affected include areas of St. John's, Bonavista, Clarenville, Conception Bay North and Bay Roberts.
Newfoundland Power says rotating outages are required due to not enough available generation to meet customer demand.
