MidAmerican Energy Company dispatched additional crews to the Quad Cities area on Tuesday because ice accumulated overnight on power lines and trees and winds are forecast to increase.
Though MidAmerican Energy customers experienced some isolated outages early Tuesday, weather conditions did not substantially impact the system. However, gusty winds may cause more significant impacts to already ice-coated power lines and tree limbs.
"When ice accumulates on power lines and the wind increases, that can cause a phenomenon we call galloping. That’s what happens when wind pushes on the lines and lifts them up, in essence causing them to gallop or jump up and down," vice president of electric operations Jim Dougherty said. “We’re also concerned about ice-covered limbs that can fall onto our lines and equipment.”
The company has dispatched additional line crews and tree trimming crews to the Quad Cities as a precaution. MidAmerican Energy dispatched the additional company and contractor crews from Iowa City, Waterloo and Des Moines, and has put additional crews on standby.
