"It’s been a challenge," Mutch Usera, senior manager of external affairs for Black Hills Power said Friday. "The stress from the snow is causing extreme weight and the lines can snap."
He said there are three key challenges with this storm: The leaves on trees and dead pine beetle trees, the heavy snow and wind conditions.
He said the crews work to fix the issues that are the easiest and quickest to fix, and work there way to the hardest
"We have snow cats and ATVs that can get us in to some of those areas," he said. "Sometimes we have to wait until snow lightens so we can get in there and assess the damage in specific areas."
"That’s why it's really hard to tell customers when restorations will take place," Usera said.
