An outage left thousands of people in Calgary, Edmonton, Medicine Hat and other parts of Alberta without power Sunday evening, while a second, unrelated outage hit two Calgary neighbourhoods early Monday morning. The first outage left nearly 18,000 homes and businesses without power for approximately 17 minutes, occurring after 9 p.m. on Sunday. Early Monday morning, and until about 6 a.m., a second outage left about 1,100 homes and businesses in the Varsity and Montgomery neighbourhoods of Calgary without power. "And that really is just a safeguard measure that's built into any power system." "This is where we actually had an electrical disruption on a power system … and this system just has safeguards in place to deal with it."
