Idaho City went dark early Friday morning after widespread power outages.
Dispatchers say the power went down at about 2:30 a.m.
Superintendent John McFarlane said school has been canceled at all three schools in Idaho City.
The town is home to Basin Elementary, Idaho City Middle School and Idaho City High School.
The cancellation will affect about 400 students.
Idaho Power has a crew onsite now, working to fix the problem.
