APS cuts power in northern Arizona as wildfire risk spikes near Flagstaff

Power went out across northern Arizona at 9 a.m. April 22, and for anyone headed toward Flagstaff or the Grand Canyon, the shutdown had immediate travel consequences: no guaranteed charging, shaky communications, and the kind of lodging, food, and fuel disruption that can turn a normal drive north into a scramble.

Arizona Public Service cut service to about 6,000 customers in high fire-risk communities around Flagstaff and another 150 customers in and around Grand Canyon National Park, excluding Grand Canyon Village. The affected areas included Doney Park, Timberline, Fernwood, Mormon Lake, Cosnino, Sunset Crater, Walnut Canyon and Valle. APS said the public safety power shutoff was meant to keep electrical equipment from starting or feeding a wildfire as strong winds, dry vegetation and low humidity lined up across the region.

That matters on a trip because the outage did not just hit houses. It hit the infrastructure travelers lean on in Coconino County: motel front desks, campground check-ins, gas pumps, food stops, phone charging, refrigeration and roadside communications. Grand Canyon National Park posted its own outage alert for some areas of Grand Canyon Village and Desert View, warning of a 12 to 24 hour interruption beginning at 9 a.m. The National Weather Service Flagstaff office had a Wind Advisory in effect from 8 a.m. to 8 p.m., which only sharpened the risk.

APS later said the shutoff was the first time weather conditions had been extreme enough to trigger a PSPS in its program, which the utility created in 2024 as part of its Comprehensive Wildfire Mitigation Plan. The company said the decision was tied to the specific power lines and equipment facing the highest wildfire risk under the forecast conditions, and noted that it maintains more than 38,000 miles of power lines as part of its mitigation work.

Service came back in stages as crews patrolled the lines and checked for damage or debris. APS restored Valle at 2:20 p.m., then locations in and around Grand Canyon National Park at 4:30 p.m., and said the remaining Flagstaff-area customers were back by about 6:45 p.m. Grand Canyon National Park was already under Stage 2 fire restrictions as of April 11 because of depleted water reserves available for fire suppression, which made the shutoff part of a much larger spring access picture: dry, windy, and one spark away from a far bigger problem.
