 Thousands of Utah residents have lost power recently just as temperatures in the state were rising. Rocky Mountain Power says some outages are for planned maintenance and others may be triggered by fire sensors to prevent larger disasters. Crews shot off power to Pleasant Grove Wednesday to replace a power pole. RMP officials say customers were notified in advance of that planned outage. Residents are complaining about the high number of unplanned outages this summer. RMP says that fire sensors are highly sensitive and may set outages into motion that are necessary during fire season.
