AltaLink’s substation, which supplies much of the industrial load in the area, had a significant drop in voltage shortly after 8:00 a.m. As a result, refineries in the area began flaring, which produces tall flames and causes dark smoke to come out of the stacks of the refineries. Flaring is a safety measure refineries take to burn excess hydrocarbons and release pressure in the plant.
AHS says air quality in the City of Edmonton is no longer being impacted.
