More than 80,000 residents in communities across Alberta lost power Sunday afternoon due to a province-wide transmission system issue. The Alberta Electrical System Operator's website reported at 2:50 p.m. two paths were out of service, one from B.C. Tara De Weerd, a spokesperson for AESO, said a lightning strike hit the B.C.-Alberta intertie — an electric power transmission line — creating a frequency issue, because so much power was being brought into Alberta at that time. Approximately 28,000 customers in Edmonton also experienced power outages in neighbourhoods across the city, De Weerd said. Fortis, an electricity distribution utility which supplies power to people outside of major centres in Alberta, said it was also impacted.
