SaskPower says a fault at a substation is to blame for a power outage that - in some places - lasted as long as four hours on Sunday afternoon.

The outage was first reported at 11:39am for Raymore, Strasbourg, Watrous, Wadena, Wynyard, Viscount, Simpson, parts of Humboldt, and surrounding areas.

Less than an hour later, another outage was reported to include Kawacatoose and area.

Power was restored in all areas at approximately 4:00pm.
