Governor Kim Reynolds says hundreds of thousands of Iowans remain without power a day after the derecho storm with hurricane-force winds swept through the state — and it may be several days before service is fully restored. At mid-day (Tuesday), the governor indicated an estimated 450-thousand Iowa homes and businesses had no electric service.“At our peak last night, there were 550,000 households without power,” Reynolds says. “Linn County had 97% without power at one point, as well as Marshall County.” The power grid has been seriously damaged in Linn, Marshall and Scott Counties.“For example, more than 22 of the large, lattice transmission towers were directly impacted,” Reynolds says. Iowa Utilities Board chairwoman Jeri Huser says service will be restored as soon as utility companies can safely do so.“Some areas of service can expect to be without power for several days as debris is cleared and downed power lines are replaced,” Huser says. Iowa utility companies are activating their mutual aid agreements with utility and tree companies in other states, to get more crews into Iowa to deal with the situation.“Utility companies have reported to the IUB and have indicated that the storm damage was one of the most destructive of record,” Huser says. Alliant Energy has announced service to neighborhoods, industries and businesses will be restored systematically. The first priority has been getting hospitals, nursing homes, fire and police departments and water systems back online.
